Abstract
The utility model provides an integrated backlight module. One corner of the bottom face of a light guide plate is provided with a right-angle concave groove, one side face of an LED (Light Emitting Diode) light source is clung to one side face of the right-angle concave groove, the bottom face and the other side face of the LED light source are clung to a heat dissipating sheet, the front face of the LED light source and the other side face of the right-angle concave groove are arranged face to face, and the heat dissipating sheet has a right-angle structure, so that the LED light source is closed in the right-angle concave groove. The integrated backlight module has the advantages that the LED light source can be effectively protected, and the LED light source and the heat dissipating sheet are structurally integrated, so that the structure is simpler, and the cost is reduced.
Description
Technical field
The utility model relates to the LED lighting field, and a kind of integrated backlight module that uses led light source specifically is provided.
Background technology
In widely used LED lamp box backlight module, LGP and led light source are independent separately, need respectively assembling during use, also need add various assembly structures, carry out the processing of section bar, not only process comparatively inconvenience of installation procedure, and cost is higher, therefore, need to a kind ofly can realize LGP and led light source integral structure, convenient use, compact conformation, cost-effective technical scheme.
The utility model content
The purpose of this utility model provides a kind of integrated backlight module easy for installation.The technical scheme that the utility model provides is as described below.
A kind of integrated backlight module, comprise led light source, fin and LGP, wherein, LGP one jiao of bottom surface be provided with a right angle groove, a side of described right angle groove is close in one side of described led light source, described fin is close in the bottom surface of described led light source and another side, and the front of described led light source is over against the another side of described right angle groove, and described fin has a right-angle structure described led light source is closed in the described right angle groove.
Wherein, described fin is L shaped, and the one side of being close to led light source is concordant with the bottom surface of described LGP, and another side extends to a side of described LGP and protrudes from described LGP.
Wherein, described fin is the right angle U-shaped, and its bottom surface is not close to part and two sides of led light source and is close to respectively bottom surface and two sides of described LGP, and protrudes from two sides of described LGP.
Wherein, described fin is the right angle U-shaped, and its bottom surface is not close to part and two sides of led light source and is close to respectively bottom surface and two sides of described LGP, and flushes in two sides of described LGP.
The utility model is designed to bottom surface of light guide plate and the corresponding structure of led light source, fin also has this design simultaneously, so just led light source can be embedded in LGP and the fin, and fin is in the outside of LGP, can also will extend along the LGP sidewall or concordant with sidewall, enlarge like this area of fin, also can better realize heat radiation.The utility model has the advantage of not only and effectively led light source is protected, and with the LGP of traditional separate type, led light source, heat radiating fin structure is realized integrated, so that structure is simpler, saves cost, and is easy to use.
