Patent claim: A light emitting device package comprising a body including a first side surface part a second side surface part opposite to the first side surface part third and fourth side surface parts adjacent to the first and second side surface parts and opposite to each other a fifth side surface part in which a cavity is disposed and a sixth side surface part opposite to the fifth side surface part a first lead frame having a first lead part disposed on a bottom of the cavity a first bonding part connected to the first lead part and bent to a first outer side area of the first side surface part of the body and a first heat radiating part bent from the first bonding part to a first recess of the third side surface part a second lead frame having a second lead part disposed on the bottom of the cavity a second bonding part connected to the second lead part and bent to a second outer side area of the first side surface part of the body and a second heat radiating part bent from the second bonding part to a second recess of the fourth side surface part and a light emitting chip disposed on at least one of the first lead part of the first lead frame and the second lead part of the second lead frame disposed on the bottom of the cavity wherein the first and second recesses are more adjacent to the sixth side surface part than the fifth side surface partthe first and second recesses include first and second areas inclined at a first angle from the third and fourth side surface parts and third and fourth areas inclined at a second angle from the first and second areas the first angle is an angle between a straight line extended from the third and fourth side surface parts and an inclined surface of the first and second areas the second angle is an angle between the straight line and an inclined surface of the third and fourth areas the second angle is smaller than the first angle the first heat radiating part of the first lead frame is disposed on the third area of the third side surface part and the second heat radiating part of the second lead frame is disposed on the fourth area of the fourth side surface part.

Related passage: The transparent covering materials may include diffusing agents or fluorescent materials.The diffusing agents are used for diffusing light which makes it possible to relax a directionality of the light emitted from the light emitting element and increase a view angle of the light emitting device.The fluorescent materials are used for converting the light emitted from the light emitting element and then convert the wavelength of the light which is emitted from the light emitting element and emitting out of the package.When the light emitting element emits a short wavelength visible light having ahigh energy organic fluorescent materials such as a perylene derivative or inorganic fluorescent materials such as ZnCdSCu YAGCe and nitrogencontaining CaOAl2O3SiO2 activated by Eu andor Cr are preferably employed.In the present invention YAGCe fluorescent material is preferably employed for obtaining a white light since both a blue light emitted from a blue light emitting element and a yellowish light as a complementary color of the blue light which is emitted from the fluorescent material when it absorbs a part of the blue light can be emitted by depending on a content of the YAGCe fluorescent materials thereby producing a highreliability whitetype light emitting device relatively easily.In a similar way the fluorescent material of the nitrogencontaining CaOAl2O3SiO2 activated by Eu andor Cr is preferably employed for obtaining a white light since both a blue light emitted from a blue light emitting element and a reddish light as a complementary color of the blue light which is emitted from the fluorescent material when it absorbs a part of the blue light can be emitted by depending on a content of the fluorescent materials of the nitrogencontaining CaOAl2O3SiO2 activated by Eu andor Cr thereby producing a highreliability whitetype light emitting device relatively easily.In addition when the fluorescent materials are fully settled to remove bubbles an irregular color of thelight emitting device can be suppressed.
