Material avoids the setting area of lamp bar, can prevent the thermal-radiating material of low heat conductivity and increase the heat between metal frame and lamp bar
Resistance.
Technical problem to be solved in the utility model is achieved by the following technical programs：
A kind of radiating subassembly of backlight, including the metal frame with bottom surface and side, it is arranged on the outer of the metal frame
Thermal-radiating material on surface and inner surface, the Heat Conduction Material on the thermal-radiating material for the inner surface for being arranged on the metal frame,
The lamp bar being arranged on the Heat Conduction Material of the metal frame side；Inner surface of the thermal-radiating material in the metal frame side
On avoid the setting area of the lamp bar, the Heat Conduction Material is set directly at the metal on the setting area of the lamp bar
On the inner surface of frame side.
Further, the thermal-radiating material is carbon nanotube ink.
Further, the thickness of the thermal-radiating material is 5 ~ 10 μm.
Further, the thermal conductivity of the thermal-radiating material is 30W/mk.

Further, the lamp bar is pasted onto by heat-conducting glue on the Heat Conduction Material of the metal frame side.
The utility model has the advantages that：Heat conduction material is provided with the inner surface of the metal frame of the radiating subassembly
Material, then the lamp bar is arranged on the Heat Conduction Material, using the Heat Conduction Material to heat caused by the lamp bar flat
Conducted on face, make the even heat of backlight various places inside, recycle the thermal-radiating material on the metal frame outer surface
Heat loss through radiation is carried out to backlight, the radiating efficiency of the thermal-radiating material can be effectively improved；And by the heat radiation material
Material avoids the setting area of the lamp bar, can prevent the thermal-radiating material of low heat conductivity and increase the metal frame and the lamp bar
Between thermal resistance.
