Abstract
The utility model provides an integrated backlight module for an LED (Light-Emitting Diode) light source. The integrated backlight module comprises an LED light source, a heat radiation fin and a light guide board, wherein the LED light source is embedded inside the heat radiation fin and is tightly adhered to the bottom face of the heat radiation fin; the heat radiation fin and a right-angle groove or the bottom face of the light guide board are adaptive to each other in shape, so that the LED light source is sealed between the heat radiation fin and the light guide board; and the LED light source is not contacted with the light guide board. The integrated backlight module for the LED light source provided by the utility model has the advantages that on the one hand, the LED light source can be effectively protected; and on the other hand, the light guide board, the light source and the heat radiation fin, which are separated in prior art, are integrated, so that the structure is simpler and the cost is saved.
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-backlit 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 carry out the integrated design of the two structure, easy to install and use, and save manufacturing cost.
The utility model content
The purpose of this utility model provides the integrated backlight module of a kind of led light source easy for installation.The technical scheme that the utility model provides is as described below.
The integrated backlight module of a kind of led light source, comprise led light source, fin and LGP, wherein, described led light source embeds described fin inside and is close to the bottom surface of fin, the right angle groove of described fin shape and described LGP or bottom surface adapt in order to described led light source is closed between fin and the LGP, and described led light source does not contact with described LGP.
Wherein, described fin shape is side by side and shares two right angle U-shapeds of a side, and described led light source is close to the bottom surface of right angle U-shaped and positive towards described LGP end face.
Wherein, described fin shape is L shaped, the one side of being close to the led light source side is concordant with the bottom surface of described LGP, another side extends to a side of described LGP and protrudes from described LGP, the front of described led light source is towards a side of described LGP, and this side has the indent slope and the slope is provided with reflector.
Wherein, described fin wraps up the four sides of described LGP fully for " mouth " shape.
Wherein, described fin is " mouth " jaggy shape with three of described LGP complete parcels, and one side be not exclusively to wrap up.
Wherein, the medial surface of described fin is provided with bayonet socket, bayonet socket can limit and inlay card on 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 and effectively led light source is protected on the one hand, on the other hand with the LGP of traditional separate type, light source, heat radiating fin structure is realized integrated, so that structure is simpler, saves cost.
