Description
Technical field
It the utility model is related to field of backlights, more particularly to a kind of radiating subassembly of backlight.
Background technology
Liquid crystal display because can not self-luminous, so need coordinate backlight use, as market is to high brightness backlight
Pursue, more and more using LED quantity in backlight, power is also increasing, heat dispersion for high brightness backlight extremely
Close important.
A kind of heat dissipation component of backlight light source is disclosed in the utility model patent that a notification number is CN202065933U,
It sets one layer of thermal-radiating material on the outer surface of the heat radiating metal pedestal of backlight, passes through thermal-radiating material actively outwards production
The mode of raw infra-red radiation is radiated.But what the heat inside backlight was unevenly distributed, close to one end of lamp bar
Temperature is higher, and one end temperature away from lamp bar is relatively low, and the radiant power of thermal-radiating material is set, causes thermal-radiating material
Radiating efficiency it is not high.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of radiating subassembly of backlight, the radiating
