The present invention relates to a light emitting device.
In general, various light emitting chips are used in a light emitting device. For example, a light emitting diode (LED) generates a small number of carriers (electrons or holes) injected using a pn junction structure of a semiconductor, and recombines them. The element using the phenomenon which emits light by this is used. Light emitting diodes consume less power and last several to several tens of times as compared to conventional light bulbs or fluorescent lamps, and are superior in terms of power consumption reduction and durability. In addition, it can be installed in a narrow space and has a strong resistance to vibration.
Since such light emitting diodes can irradiate light with high efficiency at low voltage, they are used in home appliances, electronic displays, display papers, and various automation devices. Recently, in accordance with the trend toward miniaturization and slimming of devices, light emitting diodes are also manufactured in a surface mount device (SMD) type to be directly mounted on a printed circuit board. In particular, in recent years, a light emitting device has been proposed in which a lead frame is used as a substrate substrate without using an insulator substrate and a molding part is directly formed on the lead frame.
However, due to the structure of the molding part formed only on the upper surface of the lead frame, there is a problem in that the molding part is easily spaced apart from the lead frame by external factors such as an elevated ambient temperature during the reflow process, so that an interface between the lead frame and the molding part is opened.

The lead frame unit 10 is a means for applying external power to the LED chip 130 as the LED chip 130 is mounted or electrically connected through a wire 150. A separate supporting means for supporting the unit 10, for example, an insulator substrate is not provided, and the lead frame unit 10 made of metal serves as the substrate at the same time. For example, the lead frame unit 10 includes a first lead frame 110 and a second lead frame 120 provided to be spaced apart from each other by a predetermined interval. In this case, the first and second lead frames 110 and 120 may be formed in a block shape instead of a plate shape.
In addition, at least one fixing space 20 penetrating the body in the vertical direction is formed in the first and second lead frames 110 and 120, respectively.
The fixed space 20 is formed by filling the fixed space 20 with a molding resin for forming the molding part 140 when the molding part 140 is formed on the upper surfaces of the first and second lead frames 110 and 120. As the molding resin filled in the upper surface of the first lead frame 110 and the second lead frame 120 and the molding resin filled in the fixed space 20 are integrally molded, the molding portion ( 140 is a means to firmly adhere.
As shown in the drawing, the fixed space 20 may include a region in which the first and second lead frames 110 and 120 face each other and an edge region on both sides of each of the first and second lead frames 110 and 120.

In this case, the external fixing holes 111 and 121 may preferably have stepped portions 113 and 123 formed on the sidewalls of the lower fixing holes 111 and 121 so that the area of the lower portion is wider than the top thereof. Therefore, the molding part 140 formed on the upper surfaces of the first and second lead frames 110 and 120 extends to the external fixing holes 111 and 121, and the molding part 140 formed at the lower portions of the external fixing holes 111 and 121 is formed. Interrupted by the stepped portions 113 and 123 to physically prevent the molding unit 140 from being spaced apart from the first and second lead frames 110 and 120. As such, the method of widening the area of the lower portion of the molding part 140 formed in the external fixing holes 111 and 121 than the upper portion is not limited thereto, and may be modified and implemented in various ways. Modifications according to this will be described later.
The light emitting diode chip 130 is a means for generating light by application of an external power source, and may be selectively adopted among chips that emit light in the infrared region from the infrared region. The light emitting diode chip 130 is mounted on the first lead frame 110 and is electrically connected to the second lead frame 120 through a wire 150. The wire 150 is formed of gold (Au) or aluminum (Al) through a process such as a wire bonding process.
The molding unit 140 is a means for encapsulating and protecting the LED chip 130 and the wire 150. The forming method and shape may be variously implemented. For example, a mold having a cavity having a polygonal shape or a hemispherical cross section may be formed, and the mold may be formed by a transfer molding method in which a molding resin is filled into a cavity of the mold and molded. In the present embodiment, a portion of the upper surface of the first lead frame 110 and the second lead frame 120 and the outer fixing hole (111, 121) by using a mold formed with a cavity so that the molding resin is filled in the transfer molding method Mold. Thus, the molding part 140 is integrated in the peripheral area and the fixed space 20 in which the light emitting diode chip 130 and the wire 150 are provided among the upper surfaces of the first lead frame 110 and the second lead frame 120. Is molded into.
The molding resin forming the molding part 140 may have a relatively high hardness and be formed of a transparent silicone resin or an epoxy resin. However, the present invention is not limited thereto, and any material may be used as long as the resin is transparent enough to transmit light depending on the use of the light emitting device. In addition, various kinds of phosphors (not shown) may be mixed to convert various wavelengths of light emitted from the light emitting diode chip 130 to realize various colors.

In this embodiment, the inner fixing holes 115 and 125 of various shapes such as circular, elliptical, and square are formed. In this case, as in the stepped portions 113 and 123 formed in the external fixing holes 111 and 121 in the first fixing hole 115 and 125, the side portions of the inner fixing holes 115 and 125 may have a lower area than the upper portion. As the forming parts 117 and 127 are formed, the molding part 140 may be interrupted by the stepped parts 113, 117, 123 and 127 to prevent the molding part 140 from being spaced apart from the first and second lead frames 110 and 120.
In the fixed space 20 presented as in the second embodiment, it is preferable to simultaneously form the external fixing holes 111 and 121 and the internal fixing holes 115 and 125, but only the internal fixing holes 115 and 125 without forming the external fixing holes 111 and 121. It will be able to form a fixed space 20 by forming.

For example, the third lead frame 170 is further spaced apart between the first and second lead frames 110 and 120, and the LED chip 130 is mounted on the third lead frame 170. In this case, it is preferable to insulate the bonding surface of the LED chip 130 and the third lead frame 130.

Similarly to forming the third lead frame 170, the outer fixing hole 171 and the inner fixing hole 175 is formed, and the stepped portions (173, 177) in the outer fixing hole 171 and the inner fixing hole 175 As it forms, the adhesion between the molding part 140 and the lead frame part 10 is improved. In addition, reflectors 160 may be formed on the first and second lead frames 110 and 120.
9 is an embodiment in which the shape of the fixed space is modified, and the area of the upper part when the external fixing holes 111 and 121 and the internal fixing holes 115 and 125 formed in the first and second lead frames 110 and 120 are formed. Instead of forming stepped portions 113, 117, 123, and 127 to widen the area of the lower portion, inclined surfaces 118, 119, 128, and 129 are formed in the outer fixing holes 111, 121, and the inner fixing holes 115, 125 so as to gradually widen the area from the upper side to the lower side. It was. The inclined surface 160 is not limited to the entire inner wall of the fixed space 20 as shown, but may be formed only in a portion of the inner wall of the fixed space 20. Accordingly, the molding part 140 is spaced apart from the first and second lead frames 110 and 120 by a partial shape of the molding part 140 which is filled and formed in the external fixing holes 111 and 121 and the internal fixing holes 115 and 125. Can be prevented.
