Description of drawings
Fig. 1 is the structural representation of the utility model side entering type LED-backlit module.
The specific embodiment
Below with reference to accompanying drawing, the specific embodiment of the present utility model and embodiment are described in detail, described specific embodiment is not for limiting the specific embodiment of the present utility model only in order to explain the utility model.
As shown in Figure 1, Fig. 1 is the structural representation of the utility model side entering type LED-backlit module, this side entering type LED-backlit module is used for being installed in LCD TV and shows module, be arranged in the back side of frame bracket 160, concrete, this side entering type LED-backlit module comprises LED assembly 110, backboard 120, reflector plate 130, LGP 140, with blooming 150, wherein, described LED assembly 110 is arranged on the madial wall of described backboard 120, described reflector plate 130 abuts on the bottom surface of described backboard 120 inboards, described LGP 140 be placed on described reflector plate 130 above, described blooming 150 be arranged on described LGP 140 above, center position to LCD TV on the madial wall of described middle frame bracket 160 is extended with a circle card platform 165, the end face edge of described blooming 150 is stuck in the back side of described card platform 165, is provided with offside reflection adhesive tape 180 in described LED assembly 110 side of frame bracket 160 in described.
Because the designing requirement that the LCD TV module is ultra-thin and cost control, the thickness of described LGP 140 is thinner usually, and that existing LED has usually is bigger luminous lower, so the light that existing side entering type LED-backlit module makes LED send is difficult to all incide in the described LGP 140, cause the optical efficiency of going into of LED 111 to reduce the brightness of having lost the LCD TV module.And the offside reflection adhesive tape 180 in the utility model side entering type LED-backlit module can reflect the light that described LED111 sends to described blooming 150 1 sides, to go into to inject in the described LGP 140 to the light that described blooming 150 1 sides are sent, promote the optical efficiency of going into of described LED 111 thus.
