Pursuit, more and more using LED quantity in backlight, power is also increasing, and heat dispersion is for high brightness backlight
It is most important.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of backlight.The lamp bar energy of the backlight
Area of dissipation is enough effectively increased, improves radiating efficiency.
Technical problem to be solved in the utility model is achieved by the following technical programs：
A kind of backlight, including glue frame, the light guide plate that is arranged in the glue frame, the bottom surface of the glue frame is in the leaded light
Lamp bar groove is recessed before the incidence surface of plate, lamp bar is provided with the lamp bar groove；It is provided between lamp bar and the lamp bar groove
Thermal conductive material layer.
Further, the thermal conductive material layer is metal material or thin-film material.
Further, the thermal conductive material layer is stainless steel plate, aluminium alloy plate, copper coin, graphite flake, nano-sized carbon copper foil, received
One kind in rice aluminium foil.
Further, fixed between the lamp bar and thermal conductive material layer by heat conduction glue.
Further, the bottom surface of the lamp bar groove is designed for hollow out.
Further, an at least optical film is provided with the exiting surface of the light guide plate.
Further, it is provided with reflector plate in one side of the light guide plate away from exiting surface.
Further, it is provided with anti-dazzling screen on the glue frame.
The utility model has the advantages that：Added between the bottom surface of the lamp bar of the backlight and the lamp bar groove
One layer of thermal conductive material layer, heat caused by the lamp bar can be quickly and evenly transmitted to the surface of whole thermal conductive material layer,
The area of dissipation of the lamp bar is effectively increased, and heat is distributed more uniform, improves the radiating of the backlight
Efficiency.
Brief description of the drawings
Fig. 1 is the schematic diagram of backlight provided by the utility model；
Fig. 2 is the schematic rear view of backlight 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 backlight, including glue frame 1, the light guide plate 2 that is arranged in the glue frame 1, the glue frame 1
Bottom surface is recessed lamp bar groove 11 before the incidence surface of the light guide plate 2, and lamp bar 3 is provided with the lamp bar groove 11；The lamp
Thermal conductive material layer 4 is provided between bar 3 and lamp bar groove 11.
One layer of thermal conductive material layer 4 is added between the bottom surface of the lamp bar 3 of the backlight and the lamp bar groove 11, can be by institute
The surface that heat caused by lamp bar 3 is quickly and evenly transmitted to whole thermal conductive material layer 4 is stated, effectively increases the lamp bar 3
Area of dissipation, and heat is distributed more uniform, improve the radiating efficiency of the backlight.
The lamp bar 3 includes wiring board 32 and some side-emitting LEDs 31 being arranged on the wiring board 32, if described
The light-emitting area of dry side emitting led 31 towards the incidence surface of the light guide plate 2, by heat conduction glue consolidated by the thermal conductive material layer 4
It is scheduled on the wiring board 32 of the lamp bar 3, then is fixed on by glue or double faced adhesive tape etc. in the lamp bar groove 11.
The thermal conductive material layer 4 is metal material or thin-film material, such as stainless steel plate, aluminium alloy plate, copper coin, graphite
One kind in piece, nano-sized carbon copper foil, nanometer aluminium foil.
As shown in Fig. 2 the bottom surface of the lamp bar groove 11 designs 12 for hollow out, make the thermal conductive material layer 4 and the backlight
Outer air directly contacts, and accelerates radiating efficiency.
It is provided with an at least optical film 5 on the exiting surface of the light guide plate 2, in the present embodiment, the light extraction of the light guide plate 2
Diffusion barrier, lower bright enhancement film and upper bright enhancement film are disposed with face, certainly, the number amount and type of the optical film 5 should regard demand
Depending on, it is not limited；Reflector plate 6 is provided with the one side of the light guide plate 2 away from exiting surface；It is provided with the glue frame 1
Anti-dazzling screen 7, the two-sided equal toughness of anti-dazzling screen 7, the one side backwards to the glue frame 1 is black, towards the one side of the glue frame 1
For white, black or other colors.
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.
