The third and fourth protrusions  21  and  22  may have a width ‘a’ of a portion exposed to the outside of the second side surface S 2  greater than a width of a portion disposed inward the second side surface S 1 . The outer width ‘a’ of the third and fourth protrusions  21  and  22  may be a length in the second direction.

Since the outer width a of each of the first to fourth protrusions  11 ,  12 ,  21 , and  22  is greater than the interval c, the bonding force at the outside of each of the frames  111  and  112  may be improved. The width a may be in the range of 100 micrometers or more, for example 100 to 600 micrometers. The interval c may be in the range of 350 micrometers or less, for example 50 to 350 micrometers or 50 micrometers to 200 micrometers. The ratio a/c may be 0.5 to 1.8, and when smaller than the range, the function and rigidity of each protrusion  11 ,  12 ,  21  and  22  may be degraded, and when larger than the range, the coupling force with the body may be reduced. 
     Here, the minimum width a 1  of the portion of the first to fourth protrusions  11 ,  12 ,  21 , and  22  that is coupled to the body  113  is smaller than the outer width a and may be more than 100 micrometer. When the minimum width a 1  is smaller than the above range, the frames  111  and  112  may be bent or twisted due to pressure in the injection molding process. The portion having the minimum width a 1  may correspond to the first and second recesses  15  and  25  in the second direction. The first to fourth protrusions  11 ,  12 ,  21 , and  22  may protrude from the first and second side surfaces S 1  and S 2  to a predetermined length f, and the length f may be 150 micrometers, for example, in a range from 50 to 150 micrometers. Each of the protrusions  11 ,  12 ,  21 ,  22  may be exposed for the test function. The protruding length f of the protrusions  11 ,  12 ,  21 ,  22  may be provided as a process margin during cutting, and each protrusion  11 ,  12 ,  21 ,  22  may be protrude outward from each of the side surfaces S 1  and S 2 , and the bonding force may be improved. 
     The first and third protrusions  11  and  21  may be spaced apart from the third side surface S 3 , and the second and fourth protrusions  12  and  22  may be spaced apart from the fourth side surface S 4 . The first to fourth protrusions  11 ,  12 ,  21 , and  22  may have a distance b spaced apart from the third or fourth side surfaces S 3  and S 4  of the body. The spaced distance b may be greater than or equal to 0.5 mm or greater than the outer width a of each of the protrusions  11 ,  12 ,  21 , and  22 . That is, satisfies b&gt;a, and the difference between b and a may be 0.1 mm or more. By the b&gt;a, the body  113  or the reflective portion  110 A may support the outer side of each of the protrusions  11 ,  12 ,  21 , and  22 , so that the protrusions  11 ,  12 ,  21 , and  22  are covered. 
     The third step portion  33  may be provided around the first recess  15 , and the fourth step portion  37  may be provided around the second recess  25 . Accordingly, the area of the injection gate may be increased. The outer portions of the first to fourth protrusions  11 ,  12 ,  21 , and  22  may have a stepped structure or may not have a stepped structure, but are not limited thereto. 
     The lower portion of the package body  110  may include recesses  15  and  25  in regions adjacent to the first and second side surfaces S 1  and S 2  opposite to each other. The first frame  111  may include a first side portion disposed on the first side surface S 1 . The first side portion may include a plurality of protrusions  11  and  12  and a first recess  15 . The second frame  112  may include a second side portion disposed on the second side surface S 2 . The second side portion may include the plurality of protrusions  21  and  22  and the second recess  26 . The first recess  15  may include the first recess  15  concave in the direction of the second side surface S 2  from the first side portion. The second recess  25  may be concave in the direction of the first side surface S 1  at the second side surface portion.

     The first recess  15  may be adjacent to the first side surface S 1 , and the second recess  15  may be adjacent to the second side surface S 2 . Each of the first and second recesses  15  and  25  may be spaced apart from the third and fourth side surfaces S 3  and S 4  by the same distance. The first recess  15  may be disposed below the center region of the first side surface S 1 , and the second recess  25  may be disposed below the center region of the second side surface S 2 . 
     The first recess  15  may be disposed outside the first direction of the first frame  111 . The first recess  15  may be adjacent to the first side surface S 1  of the body  113  and disposed between the first and second protrusions  11  and  12 . The first recess  15  may overlap the body  113  in the third direction. A portion of the body  113  may be exposed to the first recess  15  through the first and second protrusions  11  and  12 . The body  113  may be disposed along the side of the first frame  111  without protruding from the first recess  15  disposed in the region between the first and second protrusions  11  and  12 . The bottom of the body  113  exposed on the first recess  15  may be rough or concave. 
     The first recess  15  may be connected to the first open region  15 A opened in the first direction between the first and second protrusions  11  and  12  disposed outside the first side surface S 1 . The width or the interval c of the first open region  15 A in the second direction may be smaller than the lengths d 1  (d 1 &gt;c) of the first recess  15  in the second direction. The length d 1  is greater than or equal to two times the interval c, and is provided larger than the particle size of the epoxy molding compound, and is injected in the upper direction of the body and an injection efficiency of the molding compound injecting in the periphery direction of the cavity through the first recess  15  may improve. 
     The length d 1  in the second direction of the first recess  15  may be wider than the widths d 2  (d 1 &gt;d 2 ) in the first direction. When the width d 2  of the first direction is increased, it may be difficult to secure a distance between the bottom of the cavity  102  and the first recess  15  and moisture may penetrate after injection molding. When the width d 2  of the first direction is too small, it may not be possible to provide a space for the injection gate. 
     The second recess  25  may be disposed outside the first direction of the second frame  112 , and the second recess  25  is adjacent to the second side surface S 2  of the body  113  and may be disposed between the third and fourth protrusions  21  and  22 . The second recess  25  may overlap the body  113  in the third direction. A portion of the body  113  may be exposed to the second recess  25  through the third and fourth protrusions  21  and  22 . The body  113  does not protrude from the second recess  25  disposed in the second open region  25 A between the third and fourth protrusions  21  and  22 , and the body  113  may be disposed along the side surface of the second frame  112 . The bottom of the body  113  exposed on the second recess  25  may be rough or concave. 
     The second recess  25  may be connected to the second open region  25 A opened in the first direction between the third and fourth protrusions  21  and  22  disposed outside the second side surface S 2 . The width or the interval c of the second open region  25 A in the second direction may be smaller than the length d 1  (d 1 &gt;c) of the second recess  25  in the second direction. The length d 1  is greater than or equal to twice the interval c, and is provided larger than the particle size of the epoxy molding compound, and the injection efficiency of the molding compound injected in the upper direction of the body and a periphery direction of the cavity through the second recess  25  may improve. 
     The length d 1  in the second direction of the second recess  25  may be wider than the widths d 2  (d 1 &gt;d 2 ) in the first direction. When the width d 2  of the first direction is increased, the distance between the bottom of the cavity  102  and the second recess  25  may be narrowed, so that moisture may penetrate after injection molding. When the width d 2  of the first direction is too small, it may not be possible to provide a space for the injection gate. In the first and second recesses  15  and  25 , the length d 1  in the second direction may be 1.6 times or more, for example, 1.6 times to 2.2 times longer than the width d 2  of the first direction. The width d 2  of the first direction may be 0.5 mm or less, for example, in the range of 0.25 mm to 0.5 mm. The widths d 1  and d 2  of the first and second directions may be the widths of the regions excluding the stepped portions. 
     The first and second recesses  15  and  25  may be disposed not to overlap the bottom of the cavity  102  in the third direction. The outer width or the interval c adjacent to the first and second side surfaces S 1  and S 2  in the first and second recesses  15  and  25  may be narrower the inner width d 1  adjacent to the cavity  102 . 
     The length d 1  of the first and second recesses  15  and  25  in the second direction may be greater than the interval c, and the difference between the length d 1  and the interval c may be 2×a 2 . The length a 2  may be a length in which the first to fourth protrusions  11 ,  12 ,  21 , and  22  extend in the first and second open regions  15 A and  25 A. The length a 2  is a length in the second direction and may be provided as a passage for injecting the epoxy molding compound. The length a 2  may extend to the minimum width a 2  on both sides of the second direction than the distance c. The ratio of the minimum width a 2  to the interval c may range from 0.5 to 1. The minimum width a 2  may be at least 80 micrometers, for example, in the range of 80 micrometers to 120 micrometers. When the minimum width a 2  is smaller than the range, it may be difficult to secure the injection passage of the epoxy molding compound, and when it is larger than the range, the improvement of the molding injection efficiency may be insignificant. That is, the minimum width a 2  may be equal to or larger than the particle size of the epoxy molding compound. That is, the minimum length a 2  is a length extending from the protrusions  11 ,  12 ,  21 , and  22  to both sides of the first and second recesses  15 ,  25  and may be obtained as ½ of d 1 - c . The minimum width a 2  may be obtained as a-a 1 . The minimum width a 2  may be a width of a region where the first and second recesses  15  and  25  and the protrusions  11 ,  12 ,  21 , and  22  overlap each other in the first direction. 
     The width or depth of the third and fourth steps portions  33  and  37  in the first and second recesses  15  and  25  may be at least 80 micrometers, for example, in the range of 80 to 150 micrometers. The width or depth of the third and fourth stepped portions  33  and  37  may be formed within the range in consideration of the distance to the bottom of the cavity  102 , or when the width or depth of the third and fourth stepped portions  33  and  37  is in the second direction different from the cavity  102 , the width or depth of the third and fourth stepped portions  33  and  37  may be formed deeper than the depth of the first direction. 
     Referring to  FIGS. 2 and 3 , each of the first and second protrusions  11  and  12  and the third and fourth protrusions  21  and  22  may include a corner C 11 , and the corner C 11  may be provided in a curved or curved shape having a curvature and may be contacted with each of the first and second recesses  15  and  25 . Since the corners C 11  are provided in the curved shape, the pressure transmitted during the injection of the epoxy molding compound may be dispersed or the injection efficiency may be improved. 
     The outer side surfaces of the first recess  15  and the second recess  25  may include a round portion C 12  having a curve shape or curved shape that is convex in the second direction. The round portion C 12  may be disposed at a boundary portion between the outer side of the first recess  15  and the second recess  25  and the inner side surfaces of the first to fourth protrusions  11 ,  12 ,  21 , and  22 , respectively. The round portion C 12  may be formed in a curve shape or curved surface convex in the second direction. Since the round portion C 12  is provided in a curve shape or curved shape, the pressure transmitted during the injection of the epoxy molding compound may be dispersed, and the protruding portions of the first to fourth protrusions  11 ,  12 ,  21 , and  22  may prevent bending or boiling problems and may improve the injection efficiency of the epoxy molding compound. 
     The depth e from the first and second side surfaces S 1  and S 2  of the package body  110  to the ends of the first and second recesses  15  and  25  may be 250 micrometers or more, for example, in the range of 250 to 400 micrometers. when the depth e of the first and second recesses  15  and  25  exceeds the above range, the package size may be increased or the distance from the cavity bottom may be shortened, when it is smaller than the above range, the first and second recesses  15  and  25  may not be used as a gate region. 
     The first and second recesses  15  and  25  may be spaced apart in the first direction. The first recess  15  may be concavely disposed from the first side surface S 1  of the body  113  to a direction of the second side surface or in a direction the second frame  112  on a lower portion of the first frame  111 . The second recess  25  may be concavely disposed in the direction of the first side surface or in the direction of the first frame  111  from the second side surface S 2  of the body  113  on the lower portion of the second frame  112 . 
     The interval between the first and second recesses  15  and  25  may be spaced greater than the bottom width of the cavity  102  in the first direction. This is because when the interval between the first and second recesses  15  and  25  is narrower than the bottom width of the cavity  102 , the region into which the liquid body material is injected is not uniformly distributed or the area of the frames  111  and  112  is decreased, and a securing a moisture proof path adjacent to the cavity  102  may be a difficult problem. 
     The height or thickness of the first and second recesses  15  and  25  may be in a range of 40% or more, for example, 40% to 60% of the thicknesses of the first frame  111  and the second frame  112 . When the thickness of the first and second recesses  15  and  25  exceeds the range, the frame stiffness may be reduced. When the thickness of the first and second recesses  15  and  25  is smaller than the range, the implantation efficiency may decrease. The thickness of the first frame  111  and the second frame  112  may be 200 micrometers or more, for example, in the range of 200 to 350 micrometers. 
     Here, when the length of one side of the package body  110 , for example, the length in the second direction of the first and second side surfaces S 1  and S 2  is y 1 , the y 1  may range from 2 mm to 5 mm. This length y 1  may vary depending on the size of the light emitting device  120  and the number of mounted light emitting devices. 
     Referring to  FIGS. 4 and 5 , a portion of the body  113  overlaps with the body  113  in a region between the first and second protrusions  11  and  12  and may be disposed between the first recess  15  and the first side surface recess S 1 . 
     A portion of the body  113  overlaps with the body  113  in a region between the third and fourth protrusions  21  and  22  and is disposed between the second recess  25  and the second side surface S 2 . Herein, when a portion of the body  113  may be disposed between the first and second protrusions  11  and  12  and between the third and fourth protrusions  21  and  22 , the portion of the body  113  may protrude in a stepped structure with respect to a bottom of the body  113 . 
     The light emitting device  120  may be disposed on the second frame  112 . When the light emitting device  120  is a vertical chip, the light emitting device  120  may be electrically connected to the second frame  112  by a conductive layer. When the light emitting device  120  is a horizontal chip, the light emitting device  120  may be attached to the second frame  112  with a conductive or insulating adhesive. The light emitting device  120  may be connected to the first frame  111  by a wire  127 . Alternatively, the light emitting device  120  may be connected to the first frame  111  and the second frame  112  by wires. The conductive layer may be bonded between the second frame  112  and a lower electrode of the light emitting device  120 . The conductive layer may include one material selected from the group including Ag, Au, Pt, Sn, Cu, or an alloy thereof. The material constituting at least one of the second frame  112  and the lower electrode and the material of the conductive layer may be combined with a compound. The compound may include at least one of Cu x Sn y , Ag x Sn y , and Au x Sn y , and x may satisfy the condition of 0&lt;x&lt;1, y=1−x, x&gt;y. For example, the conductive layer may be formed using a conductive paste. The conductive paste may include a solder paste, a silver paste, or the like, and may include a multilayer or a single layer composed of a multilayer or an alloy composed of different materials. For example, the conductive layer may include an SAC (Sn—Ag—Cu) material. 
     A protection device may be disposed on at least one of the first frame  111  and the second frame  112 . The protection device may electrically protect the light emitting device  120 . The protection element may be implemented as a thyristor, a Zener diode, or a transient voltage suppression (TVS), and the Zener diode protects the light emitting device  120 A from an electro static discharge (ESD). 
     The light emitting device package may be mounted on a sub-mount or a circuit board. However, in the conventional light emitting device package is mounted on a sub-mount or a circuit board, a high temperature process such as a reflow may be applied. At this time, in the reflow process, a re-melting phenomenon occurs in the bonding region between the lead frame and the light emitting device provided in the light emitting device package, thereby weakening the stability of the electrical connection and the physical coupling. 
     However, the first bonding portion  121  and the second bonding portion  122  of the light emitting device according to the embodiment may receive driving power through the frames  111  and  112  and the conductive layer. The melting point of the conductive layer may be selected to have a higher value than the melting point of other bonding materials. Accordingly, the light emitting device package according to the embodiment does not cause re-melting even when bonded to a main substrate through a reflow process, so that the electrical connection and physical bonding force may not degraded. In addition, according to the light emitting device package according to the embodiment, the package body  110  does not need to be exposed to high temperatures in the process of manufacturing the light emitting device package. Therefore, according to the embodiment, the package body  110  may be prevented from being damaged or discolored due to exposure to high temperature. 
     According to an embodiment, the first and second recesses  15  and  25  are disposed in opposite regions of the lower portion of the package body  110  or opposite regions of each of the frames  111  and  112 , respectively, so that the light extraction efficiency may be improved.

     The light emitting device  120 A may be disposed on the package body  110 , the first frame  111 , and the second frame  112 . The light emitting device  120 A may be disposed on the body  113 . A conductive layer may be disposed between the first frame  111  and the first bonding portion  121  of the light emitting device  120 A and between the second frame  112  and the second bonding portion  122  of the light emitting device  120 A. 
     At least one or both of the first frame  111  and the second frame  112  may have an upper recess in which an upper portion is concave, and the upper recess may be a recessed region lower than the upper surface of the first frame  111  and the second frame  112 .

     Referring to  FIG. 7 , the light emitting device package may include an upper recess in at least one or both of upper portions of the frames  111  and  112  and upper portions of the body  113 . A first upper recess R 1  may be disposed the upper portion of the body  113 . The first upper recess R 1  may be disposed between the first frame  111  and the second frame  112 .

The first upper recess R 1  may be disposed under the light emitting device  120 A. The first upper recess R 1  may be provided to overlap the light emitting device  120 A in the third direction. The length of the first upper recess R 1  in the second direction may be longer than that of the second light emitting device  120 A. 
     The first resin  130  may be disposed in the first upper recess R 1 . The first resin  130  may be disposed between the light emitting device  120 A and the body  113 . The first resin  130  may contact the lower surface of the light emitting device  120 A. A portion of the first resin  130  may be disposed in the first upper recess R 1 .

A portion of the first resin  130  may be disposed between the first bonding portion  121  and the second bonding portion  122 . For example, a portion of the first resin  130  may be in contact with a side surface of the first bonding portion  121  and a side surface of the second bonding portion  122 . 
     The first resin  130  may be disposed in the first upper recess R 1  to provide a stable fixing force between the light emitting device  120 A and the body  113 . For example, the first resin  130  may directly contact the upper surface of the body  113  and the lower surface of the light emitting device  120 A.

     Referring to  FIGS. 10 and 11 , gates may be coupled through the first and second gate regions  10  and  20 , and a liquid body material may be injected. Accordingly, a reflective portion  110 A having a body  113  and a cavity may be formed to be combined with the frame portions  111 A and  112 A. The first and second gate regions  10  and  20  may be disposed on opposite sides to improve the injection efficiency of the liquid material. That is, the first and second gate regions  10  and  20  may be disposed in the farthest region on a straight line connecting the centers of both sides of the body  113 , so that the injection efficiency of the body due to the injection of the liquid is increased, and the injection efficiency of the body may be improved and the process may be simplified. In addition, the gate region is not disposed in the region between the first and second frame portions  111 A and  112 A, thereby preventing the center of the package body from being damaged when forming the body.

The description of the light emitting device  120 A will be described with reference to  FIGS. 6 to 9 . 
     The light emitting device  120 A may be disposed on the first frame  111 , the second frame  112 , and the body  113 . The light emitting device  120 A may be disposed in the cavity  102 , and the reflective portion  110 A may be disposed around the light emitting device  120 A. 
     An inner surface  103  of the cavity  102  may be inclined with respect to the horizontal bottom of the body  113 .

The inner surface  103  of the cavity  102  may include a first inner side surface S 11  and a second inner side surface S 12  in a direction in which the body  113  disposed between the first and second frames  111  and  112  passes. The first inner side surface S 11  and the second inner side surface S 12  may face each other. The first inner side surface S 11  and the second inner side surface S 12  may be inclined with respect to the bottom of the package body  110  or the horizontal cavity bottom. The first inner side surface S 11  corresponds to the third side surface S 3  of the package body  110 , and the second inner side surface S 12  may correspond to the fourth side surface S 4  of the package body  110 . 
     In the light emitting device  120 A, the first bonding portion  121  may be disposed between the light emitting structure  123  and the first frame  111 . The second bonding portion  122  may be disposed between the light emitting structure  123  and the second frame  112 . The first bonding portion  121  and the second bonding portion  122  may include a metal material. 
     The light emitting device  120 A may include one or a plurality of light emitting cells therein. The light emitting cell may include at least one of an n-p junction, a p-n junction, an n-p-n junction, and a p-n-p junction. The plurality of light emitting cells may be connected in series with each other in one light emitting device. Accordingly, the light emitting device may have one or a plurality of light emitting cells, and when n light emitting cells are disposed in one light emitting device, the light emitting device may be driven at a driving voltage of n times. For example, when the driving voltage of one light emitting cell is 3V and two light emitting cells are arranged in one light emitting device, each light emitting device may be driven at a driving voltage of 6V. Alternatively, when the driving voltage of one light emitting cell is 3V and three light emitting cells are arranged in one light emitting device, each light emitting device may be driven at a driving voltage of 9V. The number of light emitting cells arranged in the light emitting device may be one or two to five. 
     Referring to  FIGS. 16, 22, 23, 29, and 30 , the first resin  130  may be disposed between the body  113  and the light emitting device  120 A and may include an adhesive material. The first resin  130  may be adhered to the light emitting device  120 A and the body  113  and the first bonding portion  121  and the second bonding portion  122  of the light emitting device  120 A. 
     Referring to  FIGS. 15 and 16 , the light emitting device package  100 A may include a first upper recess R 1 . The first upper recess R 1  may be provided in one or a plurality in the body  113  or the upper portion of the body  113 . The first upper recess R 1  may be provided in the body  113  between the first through hole TH 1  and the second through hole TH 2 . The first upper recess R 1  may be provided in the body  113  between the first frame  111  and the second frame  112 . The first upper recess R 1  may be recessed in a direction of a lower surface on an upper surface of the body  113 . 
     The depth of the first upper recess R 1  may be smaller than the depth of the first through hole TH 1  or the depth of the second through hole TH 2 . The depth of the first upper recess R 1  may be determined in consideration of the adhesive force of the first resin  130 . In addition, the depth of the first upper recess R 1  may be determined by considering the stable strength of the body  113  and/or by the heat emitting by the light emitting device  120 A to prevent cracking of the light emitting device package  100 A. 
     The depth of the first upper recess R 1  may be in the range of 100 micrometers or less, for example, in the range of 15 to 100 micrometers, and in the case where the depth of the first upper recess R 1  is smaller than the range, the resin supporting force may be lowered, and when it is greater than the range, the rigidity of the body  113  may be degraded and the improvement of the supporting force may be insignificant and may cause light leakage through the body  113 . 
     The width of the first upper recess R 1  in the first direction may be smaller than an interval between the first bonding portion  121  and the second bonding portion  122  in the X direction of the light emitting device  120 A, and may be provided in the range of 140 micrometers or more, for example, in the range of 140 to 160 micrometers. 
     The length of the first upper recess R 1  in the second direction is smaller than the length of the light emitting device  120 A in the second direction, so that the first resin  130  may be function as a supporting protrusion under the light emitting device  120 A. The length of the first upper recess R 1  in the second direction may be longer than the length of the second light emitting device  120 A to strengthen the adhesive force in the second direction with respect to the light emitting device  120 A. 
     The depth of the first upper recess R 1  and the width in the first direction may affect the forming position and the fixing force of the first resin  130 . The depth and width of the first upper recess R 1  may be determined so that sufficient fixing force may be provided by the first resin  130  disposed between the body  113  and the light emitting device  120 A. 
     A top view shape of the first upper recess R 1  may be a polygonal shape, for example, a triangular, rectangular, or pentagonal shape. As another example, the top view shape of the first upper recess R 1  may be circular or elliptical. The first upper recess R 1  may be provided in a shape capable of receiving and supporting the first resin  130  before curing. A cross-section shape of the first upper recess R 1  may be a polygonal or a curved shape, for example, a triangular shape, a square shape, or a hemispherical shape. The structure of the first upper recess R 1  may be provided in a structure in which the supporting force does not decrease while reducing the influence on the body  113 . 
     The first upper recess R 1  may have an upper width greater than a lower width in the first direction. The first upper recess R 1  may have the upper width greater than the lower width in the first and second directions. The first upper recess R 1  may have a shape in which the upper width is wider than the lower width in the first direction. Since the first upper recess R 1  has a polygonal shape and the upper width is wider than the lower width, the first upper recess R 1  may be provided as an inclined surface. Accordingly, the first resin  130  may be guided and supported in the first upper recess R 1 . 
     The body  113  may include projections P 1  and P 2  that protrudes further from the bottom of the cavity  102  than the bottom of the cavity  102 . The cavity  102  may include a first projection P 1  and a second projection P 2 . The first inner side surface S 11  may include the first projection P 1 . The second inner side surface S 12  may include the second projection P 2 . The projections P 1  and P 2  may be disposed to correspond to at least one of the side surfaces of the light emitting device  120 A in the second direction, or may correspond to the side surfaces of the second direction. 
     The first projection P 1  may be disposed on the body  113  and the first inner surface S 11 . The first projection P 1  may be disposed on a boundary region between the body  113  and the first inner side surface S 11 . The second projection P 2  may be disposed on the body  113  and the second inner side surface S 12 . The second projection P 2  may be disposed on a boundary region between the body  113  and the second inner side surface S 12 . The first and second projections P 1  and P 2  may overlap the body  113  between the first frame  111  and the second frame  112  in a vertical direction Z. The first and second projections P 1  and P 2  may be formed on both ends of the body  113  and the first and second frames  111  and  112  at the bottom of the cavity  102 . Since the first and second protrusions  11  and  12  are formed on the body  113  and the first and second frames  111  and  112 , the rigidity of the body  113  between the first and second frames  111  and  112  may be strengthened. Therefore, the breaking strength of the light emitting device package  100 A may be improved. 
     The first projection P 1  may protrude toward the direction of the center of the cavity  102  or the direction of the light emitting device  120 A from the first inner side surface S 11 . The first projection P 1  may be adjacent to the first side surface of the light emitting device  120 A and may be spaced apart from the first side surface of the light emitting device  120 A. The second projection P 2  may protrude toward the direction of the center of the cavity  102  or the light emitting device  120 A from the second inner side surface S 12 . The second projection P 2  may be adjacent to the second side surface of the light emitting device  120 A and may be spaced apart from the second side surface of the light emitting device  120 A. The first and second side surfaces of the light emitting device  120 A may be opposite sides. 
     The distance between the first projection P 1  and the first side surface of the light emitting device  120 A may be smaller than the minimum distance between the first inner surface S 11  and the first side surface of the light emitting device  120 A. The distance between the second projection P 2  and the first side surface of the light emitting device  120 A may be smaller than the minimum distance between the second inner side surface S 12  and the second side surface of the light emitting device  120 A. The first and second projections P 1  and P 2  protrude to correspond to the first and second side surfaces opposite to each other of the light emitting device  120 A, and are disposed on the body  113  and the first and second frames  111  and  112 . By being formed in, the rigidity of the body  113  between the first and second frames  111  and  112  may be strengthened. Therefore, the breaking strength of the light emitting device package  100 A may be improved. 
     The projections P 1  and P 2  face two opposite sides from each other in the light emitting device  120 A in the second direction, and may be contacted the reflective portions  110 A having the first and second frames  111  and  112  and the cavity  102 . The projections P 1  and P 2  may be formed of or integrally formed with the same material as the body  113  and the reflective portion  110 A. 
     The distance m 2  between the first and second projections P 1  and P 2  may be smaller than the linear distance m 1  between the first and second inner side surfaces S 11  and S 12 . The straight line distance m 1  between the first and second inner side surfaces S 11  and S 12  It may be a minimum distance in the second direction Y from the bottom of the cavity  102  in the region except for the first and second projections P 1  and P 2 . The straight line distance m 1  between the first and second inner side surfaces S 11  and S 12  may be greater than the length in the second direction of the light emitting device  120 A. 
     A bottom width of the first projection P 1  may be smaller than the minimum distance between the first light emitting device  120 A and the first inner surface S 11  in the second direction. A bottom width of the second projection P 2  may be smaller than a minimum distance between the first light emitting device  120 A and the second inner side surface S 12  in the second direction. 
     The bottom width k 2  of the first projection P 1  may be greater than a width k 1  of the upper surface of the body  113  between the first and second frames  111  and  112  in the first direction. A bottom width of the second projection P 2  may be greater than the width k 1  of the upper surface of the body  113  between the first and second frames  111  and  112  in the second direction. Accordingly, the first and second projections P 1  and P 2  may contact the upper surface of the body  113  and the upper surfaces of the first and second frames  111  and  112 . Since the first and second protrusions  11  and  12  are in contact with the upper surfaces of the body  113  and the first and second frames  111  and  112 , a rigidity of the body  113  disposed between the first and second frames  111  and  112  may be strengthened. Therefore, the breaking strength of the light emitting device package  100 A may be improved. 
     A width in the second direction at the bottom of the projections P 1  and P 2  may be provided at least 30 micrometers or more to secure a contact area between the body  113  and the frames  111  and  112 . The distance between the projections P 1  and P 2  and the light emitting device  120 A may be spaced at least 50 micrometers or more, thereby reducing interference when mounting the light emitting device  120 A and reducing the influence of light distribution. 
     The body  113  disposed between the first and second frames  111  and  112  may have the width of the upper surface and a width of the lower surface thereof. As another example, the width of the upper surface of the body  113  may be larger than the width of the lower surface thereof. As another example, the body  113  may have an upper surface width smaller than a lower surface width. 
     The first and second projections P 1  and P 2  and the body  113  may be formed of the same material. In this case, the first and second projections P 1  and P 2  may be integrally formed on the body  113 . As another example, the first and second projections P 1  and P 2  and the body  113  may be different resin materials. In this case, bottom surfaces of the first and second projections P 1  and P 2  may be in contact with an upper surface of the body  113  with an interface. The first and second projections P 1  and P 2  may strengthen a strength of the body  113  between the first and second frames  111  and  112  when the reflective portion  110 A and the body  113  are integrally formed of the same material. 
     Here, in the bottom of the first projection P 1 , an area of the bottom of the first projection P 1  overlapping with the upper surface of the body  113  in the vertical direction may be larger than an area of a region overlapping with the upper surface of the first frame  111  in the vertical direction. In the bottom of the first projection P 1 , the area of the bottom of the first projection P 1  overlapping the upper surface of the body  113  in the vertical direction may be larger than an area of the region overlapping the upper surface of the second frame  112  in the vertical direction. In the bottom of the second projection P 2 , an area of the bottom of the second projection P 2  overlapping with the upper surface of the body  113  in the vertical direction may be greater than the area of the region overlapping with the top surface of the first frame  111  in the vertical direction. In the bottom of the second projection P 2 , the area of the bottom of the second projection P 2  overlapping the upper surface of the body  113  in the vertical direction may be larger than an area of the region overlapping the upper surface of the second frame  112  in the vertical direction. Accordingly, the first and second projections P 1  and P 2  have an increased contact area between the body  113  and the first and second inner side surfaces S 11  and S 12  and the first and second frames  111  and  112 , and may be supported by the first and second frames  111  and  112  to enhance the center-side rigidity of the light emitting device package. 
     As shown in  FIG. 18 , a height k 4  of the first and second projections P 1  and P 2  may be less than or equal to a depth k 3  of the cavity  102  based on a bottom of the cavity  102  or the upper surface of the frames  111  and  112 . Here, the depth of the cavity  102  is a straight line distance from the upper surface of the frames  111  and  112  to the upper surface of the reflective portion  110 A. The height k 4  of the first and second projections P 1  and P 2  may be in a range of 30% to 100% of the depth k 3  of the cavity  102 , and when smaller than the range, the bearing force may decrease. The height k 4  of the first and second projections P 1  and P 2  is lower than the height of the reflective portion  110 A (that is, a 3 ) or equal to the height k 3  of the reflective portion  110 A as shown in  FIGS. 27 and 28 . 
     As shown in  FIG. 18 , the inner surface on the side cross-sections of the first and second projections P 1  and P 2  convexly protrudes toward the light emitting device  120 A from the inclined surfaces of the first and second inner surfaces S 11  and S 12 , and may increase the overlapping area with the bottom of the cavity  102 . Accordingly, the breaking strength of the package may be improved by the first and second projections P 1  and P 2 . As another example, as shown in  FIG. 5 , the inner side surfaces of the first and second projections P 1  and P 2  may be provided to be inclined to the bottom of the cavity  102  and may reflect light emitted from the light emitting device  120 A. The inclined angles of the first and second projections P 1  and P 2  may be greater than the inclined angles of the first and second inner surfaces S 11  and S 12  based on the bottom of the cavity  102 . Accordingly, the light incident from the light emitting device  120 A may be reflected in the upward direction, and the breaking strength of the package may be increased. 
     The distance m 3  between the first upper recess R 1  and the first and second projections P 1  and P 2  may be greater than a distance between the first and second projections P 1  and P 2  and the light emitting device  120 A. As shown in  FIG. 15 , when the first upper recess R 1  does not protrude outward from the region of the light emitting device  120 A, the distance m 3  may have the above relationship. Since the first and second projections P 1  and P 2  enhance the strength of both ends of the body  113 , the length of the first upper recess R 1  in the Y direction may be longer. Even if two or more upper recesses R 1  are arrange positioned as shown in  FIG. 20 , the breaking strength of a package may be prevented from being lowered. As shown in  FIG. 20 , the minimum distance m 3  between the two recesses R 1  and R 2  and the first and second projections P 1  and P 2  may be less than a distance between the light emitting device  120 A and the first and second projections P 1  and P 2  and the light emitting device. As shown in  FIG. 20 , when a portion of the recesses R 1  and R 2  protrude outside a region of the light emitting device  120 A, the distance m 3  may have the above relationship. As shown in  FIG. 20 , the first and second projections P 1  and P 2  are disposed closer to the recesses R 1  and R 2  than the light emitting device  120 A, so that the strength of the body  113  may be supported by the recesses R 1  and R 2 . 
     Referring to  FIGS. 16 to 18 , the light emitting device package  100 A according to the present invention may include at least two through holes. The through hole may include, for example, a first through hole TH 1  and a second through hole TH 2 . Each of the first and second frames  111  and  112  may include first and second through holes TH 1  and TH 2 . 
     The first and second through holes TH 1  and TH 2  may be provided in one or plural in the first and second frames  111  and  112 , and may be provided through the upper and lower surfaces of each frame in the Z direction. By exposing the first and second bonding portions  121  and  122  through the first and second through holes TH 1  and TH 2 , a conductive material filled in the first and second through holes TH 1  and TH 2  is be provided through electrical path and heat dissipation path. 
     As shown in  FIG. 16 , the width W 1  of the upper regions of the first and second through holes TH 1  and TH 2  in the X direction may be provided to be smaller than or equal to the width of the first and second bonding portions  121  and  122 . The widths of the first and second through holes TH 1  and TH 2  in the X direction may be the same or different from each other. Widths of the first and second bonding portions  121  and  122  in the X direction may be the same or different from each other. 
     The width W 1  of the upper region of the first and second through holes TH 1  and TH 2  in the X direction may be equal to or smaller than the width W 2  of the lower region. Since the width W 1  of the upper region of the first and second through holes TH 1  and TH 2  is equal to or narrower than the width W 2  of the lower region, it is possible to prevent the rigidity of the frames  111  and  112  from being lowered and may provide in an electrical path. 
     The length of the upper regions of the first and second through holes TH 1  and TH 2  in the Y direction may be smaller than or equal to the length of the first and second bonding portions  121  and  122 . The lengths of the first and second through holes TH 1  and TH 2  in the Y direction may be different or the same from each other. The lengths of the first and second bonding portions  121  and  122  in the Y direction may be different or the same from each other. 
     The upper area of each of the through holes TH 1  and TH 2  may have a range of 30% or more, for example, 30% to 100% of an area of the lower surface of each of the bonding portions  121  and  122 . In addition, the through holes TH 1  and TH 2  and the bonding portions  121  and  122  may have regions facing each other. Therefore, the first bonding portion  121  of the light emitting device  120 A and the first frame  111  may be attached by a material provided in the first through hole TH 1 . The second bonding portion  122  of the light emitting device  120 A and the second frame  112  may be attached by a material provided in the first through hole TH 1 . 
     The distance from the upper region of the second through hole TH 2  to an end of the side surface of the second bonding portion  122  in the X direction may be provided at 40 micrometers or more, for example, in a range of 40 to 60 micrometers. When the distance is 40 micrometers or more, a process margin may be secured so that the second bonding portion  122  is not exposed from the bottom surface of the second through hole TH 2 . Also, when the distance is less than 60 micrometers, an area of the second bonding portion  122  exposed to the second through hole TH 2  may be secured. Since the resistance of the second bonding portion  122  may be lowered, current input may be smoothly inputted into the second bonding portion  122  exposed by the second through hole TH 2 . 
     The first and second through holes TH 1  and TH 2  may have vertical side surfaces with the same width as the upper region and the lower region. Alternatively, the first and second through holes TH 1  and TH 2  may have a curved surface in which the width of the upper region is greater than the width of the lower region and the periphery surfaces of the through holes TH 1  and TH 2  are convex. 
     As another example, the through holes TH 1  and TH 2  may be provided in a shape in which the width of the X or Y direction gradually decreases from the lower region to the upper region. As another example, the periphery surface between the upper and lower regions of the first and second through holes TH 1  and TH 2  may be a plurality of inclined planes having different slopes, curved surfaces having curvatures, or curved surfaces having different curvatures. 
     An interval between the first through hole TH 1  and the second through hole TH 2  in the lower region of the first frame  111  and the second frame  112  may be provided, for example, in a range of 100 micrometers or more, for example, 100 micrometers to 600 micrometers. The distance between the through holes TH 1  and TH 2  may be a minimum distance for preventing an electrical short between the electrodes when the light emitting device package  100 A may be mounted on a circuit board or a sub-mount. The interval between the through holes TH 1  and TH 2  may vary depending on the size of the light emitting device  120 A. 
     As shown in  FIGS. 15 and 16 , the light emitting device package  100 A according to the embodiment may include a first conductive layer  321  and a second conductive layer  322 . The first conductive layer  321  may be spaced apart from the second conductive layer  322 . 
     The first conductive layer  321  may be provided in the first through hole TH 1 . The first conductive layer  321  may be disposed under the first bonding portion  121 . The width and length of the first conductive layer  321  in the X and Y directions may be provided smaller than the width and length of the first bonding portion  121 . 
     The first bonding portion  121  may have a width in the X direction perpendicular to the Z direction in which the first through hole TH 1  is formed. The width of the first bonding portion  121  may be larger than the width W 2  of the first through hole TH 1  in the X direction. 
     Each of the frames  111  and  112  and the bonding portions  121  and  122  may be combined by an intermetallic compound layer. The intermetallic compound may include at least one of Cu x Sn y , Ag x Sn y , and Au x Sn y , and the x may satisfy a condition of 0&lt;x&lt;1, y=1−x, and x&gt;y. 
     The conductive layer  321  may be provided as a conductive material in at least one or both of the through holes TH 1  and TH 2 . The conductive layer  321  disposed in the first through hole TH 1  is in contact with the lower surface of the first bonding portion  121  and the first frame  111  and may be electrically connected to the first bonding portion  121 . The conductive layer  321  disposed in the second through hole TH 2  is in contact with the lower surface of the second bonding portion  122  and the second frame  112  and may be electrically connected to the second bonding portion  122 . The conductive layer  321  disposed in the first and second through holes TH 1  and TH 2  may be filled in a range of 30% or more, for example, 30% to 100% of the volume of the through holes TH 1  and TH 2 . When it is smaller than the above range, the electrical reliability may be lowered. When it is larger than the above range, the bonding force with the circuit board may be lowered due to a protruding of the conductive layer. The material of the conductive layer  321  will be described with reference to  FIG. 9 . 
     The bonding portions  121  and  122  of the light emitting device  120 A may be formed with an intermetallic compound (IMC) layer formed between the conductive layer  321  and the frames  111  and  112  by a forming process the conductive layer  321  or a heat treatment process after the conductive layer  321  is provide and the material constituting the conductive layer  321 . The intermetallic compound layer will be referred to the description of the first embodiment. 
     An alloy layer may be formed between the conductive layer  321  and the frames  111  and  112 . The alloy layer may be formed on the surfaces of the through holes TH 1  and TH 2  of the frames  111  and  112 . The alloy layer may include the intermetallic compound layer having at least one selected from the group consisting of AgSn, CuSn, AuSn, and the like. 
     Here, an alloy layer may be formed by bonding between the material constituting the conductive layer  321  and the metal of the frames  111  and  112 . Accordingly, the conductive layer  321  and the frames  111  and  112  may be physically and electrically bonded stably. The alloy layer may include at least one intermetallic compound layer selected from the group including AgSn, CuSn, AuSn, and the like. The intermetallic compound layer may be formed by combining a first material and a second material, the first material may be provided from the conductive layer  321 , and the second material may be provided the bonding portions  121  and  122  or the frames  111  and  112 . The intermetallic compound layer may have a higher melting point than other bonding materials. 
     The depths of the first and second through holes TH 1  and TH 2  may be equal to the thicknesses of the first and second frames  111  and  112 . The depth of the first and second through holes TH 1  and TH 2  may be equal to the thickness of the body  113 . For example, the depth of the first through hole TH 1  may be provided in a range of 180 micrometers or more, for example, 180 to 300 micrometers. 
     When the depth of the first upper recess R 1  is t 1  and the depths of the through holes TH 1  and TH 2  are t 2 , for example, the thickness difference of the depth t 2 −t 1  may be selected at least 100 micrometers or more. This is to consider the thickness of the injection process that may provide a crack free of the body. According to an embodiment, a ratio t 2 /t 1  of t 1  depth to t 2  depth may be provided as 2 to 10. For example, when the depth of t 2  is provided at 200 micrometers, the depth of t 1  may be provided at 20 micrometers to 100 micrometers. 
     The light emitting device package  100 A according to the embodiment of the present invention may include a molding member  140 . The molding member  140  will be referred to the description of the first embodiment. 
     When the light emitting device package  100 A is bonded to a main board through a reflow process, re-melting does not occur, and thus, electrical connection and physical bonding force are not degraded. In addition, the package body  110  does not need to be exposed to high temperature in the process of manufacturing the light emitting device package. Therefore, the package body  110  may be exposed to high temperature to prevent damage or discoloration. Accordingly, the selection range for the material constituting the body  113  may be widened. 
     The body  113  may include a first upper recess R 1 , and the projections P 1  and P 2  may be in contact with the body  113  and the frames  111  and  112 . Accordingly, the strength of the body  113  between the frames  111  and  112  may be prevented from being lowered. It may also improve the breaking strength in the center region of the package. 
       FIGS. 20 and 21  are plan views and E-E side cross-sectional views showing modified examples of the light emitting device package according to the embodiment. 
     Referring to  FIGS. 20 and 21 , the light emitting device package  100 A includes first and second projections P 1  and P 2 . The first and second projections P 1  and P 2  may be disposed at both ends of the body  113  disposed between the plurality of frames  111  and  112 . The first and second projections P 1  and P 2  may contact both ends of the body  113  and upper surfaces of the plurality of frames  111  and  112 . The first and second projections P 1  and P 2  may improve the breaking strength in the third direction of the light emitting device package  100 A. An interval between the first projection P 1  and the second projection P 2  may be longer than the length of the light emitting device  120 A in the second direction. 
     The body  113  disposed between the plurality of frames  111  and  112  includes a plurality of upper recesses R 1  and R 2 . A portion of each of the plurality of upper recesses R 1  and R 2  may overlap the light emitting device  120 A in the third direction or the vertical direction. A portion of the plurality of upper recesses R 1  and R 2  partially overlaps the light emitting device  120 A, so that the first resin  130  adhered between the body  113  and the light emitting device  120 A may be introduced into the plurality of upper recesses R 1  and R 2  and combined as a support protrusion. 
     Among the plurality of upper recesses R 1  and R 2 , the first upper recess R 1  protrudes outward from the first side surface of the light emitting device  120 A, and the second upper recess R 2  may protrude outward from the second side surface opposite to the first side surface of the light emitting device  120 A. The region overlapping the light emitting device  120 A among the upper recesses R 1  and R 2  may have a length in a second direction of 100 micrometers or less, for example, in a range of 30 to 100 micrometers. Each of the upper recesses R 1  and R 2  overlaps the light emitting device  120 A at least 30 micrometers or more, thereby providing a path through which the first resin  130  disposed below the light emitting device  120 A flows, and it may be arranged smaller than the above range, to reduce the light loss. The first resin  130  may be exposed to the outside of the light emitting device  120 A. 
     In the plurality of upper recesses R 1  and R 2 , an overlapping area with the light emitting device  120 A may be reduced compared to the structure of  FIG. 15 . Accordingly, it is possible to reduce the problem that light emitted to the lower surface of the light emitting device  120 A passes through the upper recesses R 1  and R 2  to the bottom of the body, and prevents the first resin  130  from leaking out and an inflow of the first resin  130  may be guided. The first resin  130  is attached and cured between the body  113  and the lower surface of the light emitting device  120 A, and between the light emitting device  120 A and the frames  111  and  112 , and the upper recess R 1  and R 2  may strengthen the supporting force of the first resin  130  introduced and may function as a dam. 
     The minimum interval between the plurality of upper recesses R 1  and R 2  may be smaller than the length of the second direction of the light emitting device  120 A, and the maximum interval may be greater than the length of the second direction of the light emitting device  120 A. Accordingly, the first resin  130  under the light emitting device  120 A may easily flow into the recesses R 1  and R 2  and may reduce light loss. 
     Each of the plurality of upper recesses R 1  and R 2  may have a top view shape in a triangular, square, or pentagonal shape. As another example, the upper recesses R 1  and R 2  may have a top view shape in a circular shape or an ellipse shape, and may provide a shape capable of guiding the first resin  130 . The upper recesses R 1  and R 2  may have a polygonal shape or a curved shape in a side cross section, for example, a triangular shape, a square shape, or a hemispherical shape. The structures of the upper recesses R 1  and R 2  may be provided in a structure in which the supporting force does not decrease while reducing the influence on the body  113 . 
     The upper recesses R 1  and R 2  may have an upper width wider than a lower width in a first direction. The upper recesses R 1  and R 2  may have an upper width wider than a lower width in the first and second directions. The upper recesses R 1  and R 2  may have a shape in which an upper width is wider than a lower width in the first direction. The upper recesses R 1  and R 2  may have a polygonal shape and have the upper width wider than the lower width, so that the upper recesses R 1  and R 2  may be provided as inclined surfaces. Accordingly, the first resin  130  may be guided and supported in the upper recesses R 1  and R 2 . 
     The maximum interval between the plurality of recesses R 1  and R 2  may be smaller than the minimum interval m 2  between the plurality of projections P 1  and P 2 . Each of the plurality of recesses R 1  and R 2  may be adjacent to the projections P 1  and P 2  at a predetermined distance m 3  and may overlap each other in the second direction. Accordingly, the projections P 1  and P 2  may prevent the rigidity of the body  113  from which the rigidity is reduced by each of the upper recesses R 1  and R 2 . An interval m 3  between the first upper recess R 1  and the first projection P 1  may be smaller than an interval between the first upper recess R 1  and the second recess R 2 . The interval m 3  between the first upper recess R 1  and the first projection P 1  may be less than the minimum interval between the first upper recess R 1  and the first inner side surface S 11  of the cavity  102 . The interval m 3  between the second recess R 2  and the second projection P 2  may be smaller than an interval between the first upper recess R 1  and the second recess R 2 . The distance m 3  between the second recess R 2  and the second projection P 2  may be smaller than the minimum interval between the second recess R 2  and the second inner side surface S 12  of the cavity  102 . Since the first and second recesses R 1  and R 2  are disposed adjacent to the projections P 1  and P 2 , the rigidity of the body  113  in the first and second directions may be strengthened. 
     The bottom width of the projections P 1  and P 2  in the first direction may be greater than a width of the upper surface of the body  113 , and the width of the upper surface of the body  113  may be greater than a width of the upper surfaces of the upper recesses R 1  and R 2 . The projections P 1  and P 2  disposed on both sides of the body  113  in the second direction may correspond each other or face each other, or their bottom centers may be arranged on a straight line such as the center of the upper recesses R 1  and R 2 . 
     As another example, as shown in  FIG. 31 , the projections P 1  and P 2  may be disposed in opposite directions of the body  113  and may be disposed to be offset from each other, or the center of the upper recess R 1  and the center of the projections P 1  and P 2  may be arranged the same centers on different straight lines. The projections P 1  and P 2  may be displaced by the structures of the frames  111  and  112 . For example, the first projection P 1  is disposed on the body  113  closer to the first through hole TH 1  than the second through hole TH 2 , and the second projection P 2  ma be disposed on the body  113  closer to the second through hole TH 2  than the first through hole TH 1 . The first upper recess R 1  disclosed in  FIG. 31  may be disposed in one or a plurality. 
     Referring to  FIG. 32 , the light emitting device package may include through holes TH 1  and TH 2  in at least one or both of the frames  111  and  112 . One or a plurality of openings R 11  may be disposed in the body  113  between the frames  111  and  112 . The opening R 11  may be disposed between the first and second through holes TH 1  and TH 2 . The opening R 11  may be provided between the first projection P 1  and the second projection P 2 . The opening R 11  may penetrate from the upper surface of the body  113  to the lower surface. The opening R 11  may be disposed under the light emitting device  120 A. The opening R 11  may be provided to overlap the light emitting device  120 A in the third direction. As shown in  FIGS. 20 and 21 , a plurality of openings R 11  may be disposed, at least one of the plurality of openings may pass through the body  113 , and the other opening may not pass through the body  113 . The location of the opening R 11  may be disposed under the center of the light emitting device, and may be disposed to overlap at least a portion below both sides. 
     The first resin  130  may be disposed in the opening R 11 . The first resin  130  may be disposed between the light emitting device  120 A and the body  113 . The first resin  130  may be disposed between the first bonding portion  121  and the second bonding portion  122 . For example, the first resin  130  may contact the side surface of the first bonding portion  121  and the side surface of the second bonding portion  122 . When the first resin  130  is formed, the first resin  130  may be formed in the opening R 11  after a support sheet is disposed on the bottom of the package body  110 . 
     According to an embodiment of the present disclosure, the depth of the opening R 11  may be equal to the thickness of the frames  111  and  112 . A width in the first direction of the opening R 11  may be smaller than a gap between the frames  111  and  112 . The width of the opening R 11  may be provided in the long axis direction of the light emitting device  120 A. The width in the first direction of the opening R 11  may be smaller than the upper width in the first direction of the through holes TH 1  and TH 2  or the maximum width in the first direction of the projections P 1  and P 2 . The length of the opening R 11  may be smaller or larger than the length in the long axis direction of the light emitting device  120 A, for example, the length in the second direction. The opening R 11  may be provided in a narrow width toward the lower direction. 
     In the light emitting device package according to the embodiment of the present invention, an opening R 11  having a penetrating shape may be further disposed below the body  113  to strengthen the coupling with the body  113 . 
     As shown in in  FIG. 33 , the second resin  135  may be disposed around an outer periphery of the light emitting device  120 A. The second resin  135  may be adhered between the first and second frames  111  and  112  and an outer lower surface of the light emitting device  120 A. The second resin  135  may reflect light incident from the light emitting device  120 A. The thickness of the second resin  135  may be smaller than the distance between the light emitting device  120 A and the frames  111  and  112 . Accordingly, the second resin  135  may be minimized to rise up to the side of the light emitting device  120 A. 
     The second resin  135  may be formed in a continuous ring shape or a frame shape along the periphery of the light emitting device  120 A, or may be formed in a discontinuous ring shape or a frame shape spaced apart from the body  113 . 
     For example, the second resin  135  may include at least one of an epoxy-based material, a silicon-based material, a hybrid material including an epoxy-based material and a silicon-based material. The second resin  135  may improve adhesion between the light emitting device  120 A and the first and second frames  111  and  112 . 
     As shown in  FIGS. 34 and 35 , the body  113  may have only one projection P 1  disposed on a portion of the body  113 . The projection P 1  may be in contact with the upper surfaces of the frames  111  and  112  and the upper surface of the body  113  to strengthen the partial breaking strength of the partial region. In this case, the first upper recess R 1  may be disposed in the center region or the outer region of the light emitting device  120 A in the body  113 . As another example, the first upper recess R 1  may be disposed to partially protrude to the outside of the light emitting device in a region adjacent to the projection P 1 , thereby preventing the strength of the body  113  from being lowered. As another example, the first upper recess R 1  may protrude in a region adjacent to the second inner side surface S 12  opposite to the projection P 1  and partially overlap the light emitting device  120 A. By arranging the projections P 1  singly, an alignment position of the light emitting device  120 A may be set based on the projections P 1 . 
     Referring to  FIGS. 26 to 28 , the heights of the projections P 3  and P 4  may be the same as the height of the cavity. By increasing the heights of the projections P 3  and P 4 , the support force between the reflective portion  110 A and the bottom of the cavity  102  may be strengthened, thereby improving the breaking strength of the light emitting device package  100 A. The projections P 3  and P 4  may be adhered to an upper surface of the body  113  and an upper surface of the frames  111  and  112 , and disposed on the inner surfaces S 11  and S 12  of the cavity  102 . 
     The maximum width of the projections P 3  and P 4  in the first direction may be greater than one time and three times less than the upper width of the first direction of the body  113 . When the maximum width of the projections P 3  and P 4  in the first direction is smaller than the range, the improvement of the breaking strength may be insignificant. When the maximum width of the projections P 3  and P 4  is smaller than the range, the light distribution may affect and the breaking strength may limit. The first and second projections P 1  and P 2  are in contact with the upper surfaces of the body  113  and the first and second frames  111  and  112 , and thus the rigidity of the body  113  between the first and second frames  111  and  112  may be strengthened. Therefore, the breaking strength of the light emitting device package  100 A may be improved. 
     As shown in  FIG. 27 , the projections P 3  and P 4  may have the minimum interval in a second direction smaller than the minimum distance between the inner side surfaces of the cavity  102 . The width of the second direction at the bottom of the projections P 3  and P 4  may be formed to be at least 30 micrometers or more, thereby ensuring a contact area between the body  113  and the frames. The projections P 3  and P 4  may be separated from the light emitting device  120 A by at least 50 micrometers or more in the second direction, thereby reducing interference when the light emitting device  120 A may mounted and reducing the influence of light distribution. 
     Inner surfaces of the projections P 3  and P 4  may be provided as inclined regions corresponding to the side surfaces of the light emitting device  120 A. The inner surfaces of the projections P 3  and P 4  may be gradually further away from the light emitting device  120 A with respect to the side surface of the light emitting device  120 A. Inner surfaces of the projections P 3  and P 4  may improve light extraction efficiency. The inner surfaces of the projections P 3  and P 4  may increase the contact area with the molding member  140 . Here, the projections P 3  and P 4  may include a columnar shape, and the projections P 3  and P 4  may be flat surfaces. The flat upper surfaces of the projections P 3  and P 4  may be provided as a step difference from the upper surface of the reflective portion  110 A. This stepped surface may be provided as a structure on which other sheets or members may be mounted. 
     As shown in  FIG. 28 , the inner surfaces of the projections P 3  and P 4  may gradually widened as a distance from the light emitting device  120 A to the upper surface with respect to the side surface of the light emitting device  120 A. The inner surfaces of the projections P 3  and P 4  may have a curved surface concave in the direction of the inner surfaces S 11  and S 12  of the cavity. The concave curved surface may be increased a contact area with the molding member  140 . The projections P 3  and P 4  may be gradually widened further toward the upper surface with respect to the light emitting device  120 A based on the side surface of the light emitting device  120 A. 
     Referring to  FIGS. 29 and 30 , in the modified examples of the through holes of the light emitting device package, since side surfaces of the through holes TH 3  and TH 4  are formed in a curved surface, and the width or diameter thereof may gradually become smaller toward the upper direction. Or the side surfaces of the through holes TH 3  and TH 4  may be formed as curved surfaces having different curvatures, and a radius of curvature of the lower side thereof may be greater than a radius of curvature of the upper side thereof. The curved surface may be a curved surface that is convex outward from the center of the through holes TH 3  and TH 4 . The curved surface having different curvatures in the through holes TH 3  and TH 4  may have one or more inflection points. 
     According to the embodiment of the present invention, the bonding portions  121  and  122  of the light emitting device  120 A are disposed above the through holes TH 3  and TH 4  on the through holes TH 3  and TH 4 , but a portion of the bonding portions  121  and  122  or a metal conductors  51 A and  52 A may be disposed in through holes TH 3  and TH 4  as shown in  FIG. 30 . 
     As shown in  FIG. 30 , the conductors  51 A and  52 A of the bonding portions  121  and  122  of the light emitting device  120 A may be disposed less than 10% of the area of the lower surface of the light emitting device  120 A. For example, the maximum areas of the conductors  51 A and  52 A of the bonding portions  121  and  122  may be provided smaller than the upper areas of the through holes TH 3  and TH 4 . Accordingly, the conductors  51 A and  52 A of the bonding portions  121  and  122  of the light emitting device  120 A may be inserted into the through holes TH 3  and TH 4 . The lower surfaces of the conductors  51 A and  52 A of the bonding portions  121  and  122  of the light emitting device  120 A may be lower than the upper surfaces of the body or the frames  111  and  112 . The conductors  51 A and  52 A of the bonding portions  121  and  122  of the light emitting device  120 A are disposed in the through holes TH 3  and TH 4 , and may be coupled with the conductive layers  321  disposed in the through holes TH 3  and TH 4 . The conductive layer  321  may contact around the conductors  51 A and  52 A of the bonding portions  121  and  122  of the light emitting device  120 A to improve adhesion to the light emitting device  120 A. In this case, power may be supplied to each bonding portion of the light emitting device  120 A through the conductive layer  321 . The conductors  51 A and  52 A of the light emitting device  120 A according to the embodiment may be applied to other light emitting devices, but are not limited thereto.

The conductors  51 A and  52 A may be provided in a single layer or multiple layers. 
     The conductors  51 A and  52 A of the light emitting device  120 A may be formed with an intermetallic compound (IMC) layer formed between the conductive layer  321  and the frames  111  and  112  by a forming process the conductive layer  321  or a heat treatment process after the conductive layer  321  is provide and the material constituting the conductive layer  321 . The conductive layer  321  may include one material selected from the group consisting of Ag, Au, Pt, Sn, Cu, Zn, In, Bi, Ti, or an alloy thereof. However, the present invention is not limited thereto, and a material capable of securing a conductive function may be used as the conductive layer  321 . For example, the conductive layer  321  may be formed using a conductive paste. The conductive paste may include a solder paste, a silver paste, or the like, and may include a multilayer or a single layer composed of a multilayer or an alloy composed of different materials. For example, the conductive layer  321  may include a SAC (Sn—Ag—Cu) material. 
     For example, an alloy layer may be formed by bonding between a material forming the conductive layer  321  and a metal of the frame. The alloy layer may include at least one intermetallic compound layer selected from the group including AgSn, CuSn, AuSn, and the like. 
     The frames  111  and  112  according to the embodiment include first and second metal layers L 1  and L 2 , and the first metal layer L 1  may include Cu, Ni, and Ti as a base layer, and may be formed as a single layer or a multilayer. The second metal layer L 2  may include at least one of Au, Ni layers, and Ag layers. When the second metal layer L 2  includes the Ni layer, since the Ni layer has a small change in thermal expansion, even when its size or arrangement position of the package body is changed by thermal expansion, and the position of the light emitting device disposed on the Ni layer may be stably fixed by the Ni layer. When the second metal layer L 2  includes an Ag layer, the Ag layer may efficiently reflect light emitted from the light emitting device disposed on the Ag layer and improve luminous intensity. When the second metal layer L 2  includes the Au layer, bonding strength with the bonding portions  121  and  122  of the light emitting device  120 A may be improved and reflection efficiency may be improved. 
     The conductive layer  321  may be filled to 100% or less in the through holes TH 1  and TH 2 , for example, to be filled in a range of 30% to 100%. When it is lower than the above range may be reduced, the conductive properties may be lowered. 
     An alloy layer L 3  may be formed between the conductive layer  321  and the frames  111  and  112 . The alloy layer L 3  may be formed by bonding between the material constituting the conductive layer  321  and the second metal layer L 2  of the frames  111  and  112 . The alloy layer L 3  may be formed on the surfaces of the through holes TH 1  and TH 2  of the frames  111  and  112 . The alloy layer L 3  may include an intermetallic compound layer having at least one selected from the group consisting of AgSn, CuSn, AuSn, and the like.
