Description

A kind of radiating subassembly of backlight
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 Component can effectively make the uniform heat distribution inside backlight, improve the radiating efficiency of thermal-radiating material.
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, the Heat Conduction Material being arranged on the inner surface of the metal frame, it is arranged on the metal frame side Heat Conduction Material on lamp bar.
Further, the thermal-radiating material is additionally arranged on the inner surface of the metal frame, and the Heat Conduction Material is set On the thermal-radiating material of the metal frame inner surface.
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 Heat Conduction Material is graphite flake or copper foil.
Further, the lamp bar is pasted onto on the Heat Conduction Material of the metal frame side.
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.
Brief description of the drawings
Fig. 1 is the schematic diagram of radiating subassembly provided by the utility model;
Fig. 2 is the schematic diagram of another radiating subassembly provided by the utility model.
Embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
As shown in figure 1, a kind of radiating subassembly of backlight, including the metal frame 1 with bottom surface and side, be arranged on it is described Thermal-radiating material 2 on the outer surface of metal frame 1, the Heat Conduction Material 3 being arranged on the inner surface of the metal frame 1, it is arranged on Lamp bar 4 on the Heat Conduction Material 3 of the side of metal frame 1.
It is provided with Heat Conduction Material 3 on the inner surface of the metal frame 1 of the radiating subassembly, then the lamp bar 4 is arranged on described On Heat Conduction Material 3, heat caused by the lamp bar 4 is conducted in the plane using the Heat Conduction Material 3, made in backlight The even heat of portion everywhere, the thermal-radiating material 2 on the outer surface of metal frame 1 is recycled to carry out heat loss through radiation to backlight, The radiating efficiency of the thermal-radiating material 2 can be effectively improved.
More preferably, it is described to lead as shown in Fig. 2 the thermal-radiating material 2 is additionally arranged on the inner surface of the metal frame 1 Hot material 3 is arranged on the thermal-radiating material 2 of the inner surface of metal frame 1, to increase the radiating surface of the thermal-radiating material 2 Product, improve the heat dispersion of backlight.
Preferably, the thickness of the thermal-radiating material 2 is 5 ~ 10 μm, and thermal conductivity is 30W/mk or so, optimal to be received for carbon Mitron ink.
The Heat Conduction Material 3 preferably has the material of Thermal conductivity, such as copper foil etc., especially with excellent planar The material of heat conductivility, such as graphite flake etc..
The lamp bar 4 is preferably but not limited to be pasted onto on the Heat Conduction Material 3 of the side of metal frame 1 by heat-conducting glue 5;Institute Stating lamp bar 4 includes wiring board 41 and some luminescent devices 42 being arranged on the wiring board 41, and the wiring board 41 is away from institute The one side for stating some luminescent devices 42 is pasted onto on the Heat Conduction Material 3;The wiring board 41 preferably FPC, the photophore Part 42 is preferably LED.
Embodiment described above only expresses embodiment of the present utility model, and its description is more specific and detailed, but simultaneously Therefore the limitation to the utility model patent scope can not be interpreted as, as long as using equivalent substitution or the form of equivalent transformation institute The technical scheme of acquisition, it all should fall within the scope of protection of the utility model.
