's.Backlight and LCDs, which are combined, constitutes LCD MODULE.LCD backlight is the uniform photograph of a plane
Bright device, cathode fluorescent tube or LED light bar as light source are arranged in the both sides or one side of whole backlight.Cold-cathode lamp
Pipe is line source, and LED is spot light, and this light source, which is converted to area source, needs to use light guide plate.Light guide plate is typically by high printing opacity
The acrylic plastics of rate are made, and surface unusual light is smooth, so that most of internal light can be regular on its flat surface
Total reflection, without injecting to outside light guide plate.The bottom of the light guide plate of liquid crystal display is printed on the site of white.In leaded light
Plate is printed on the position of site, the no longer regular total reflection of light but can be to projecting above light guide plate.Control each position net
How much irradiant the density can control light guide plate of point is in this position.The light guide plate mesh point of sophisticated design can allow two
The paving of the incident uniform light in side is dispersed in whole plane.Blooming piece can be placed again above light guide plate, and these diaphragms play
Even light, and wide-angle light is converged for effects such as front observations.
But some drawbacks in use be present in traditional LED backlight module, such as：Traditional LED backlight module
Some heats can be all given out in use, if these heats are discharged not in time, the easily projection to light produces certain
Adverse effect, causes the projection of light uneven, makes imaging effect poor.
Utility model content
The purpose of this utility model is to provide a kind of Multifunctional LED backlight module, to solve to carry in above-mentioned background technology
The problem of going out.
To achieve the above object, the utility model provides following technical scheme：A kind of Multifunctional LED backlight module, including
Metal shell, reflector plate, LED light bar and radiator fan, the lateral edges of metal shell one are fixedly welded with retainer plate, described solid
Ding Quan tops uniformly offer screwed hole, and the screwed hole internal whorl is connected with bolt, and the metal shell bottom even is set
Heat emission hole is equipped with, the metal shell inwall fixed placement has reflector plate, is provided between the reflector plate and metal shell scattered
Hot chamber, the reflector plate top are installed with LED light bar, and the LED light bar top is fixedly installed light source, the reflector plate
Top and metal shell are fixedly connected with blooming piece, and the metal shell side is fixedly installed fresh air inlet, outside the metal
Shell is fixedly connected with discharge pipe away from fresh air inlet side, and the exhaust vent other end is installed with radiator fan.
Further, the reflector plate periphery is arranged to arc groove.
Further, the reflector plate is fixed on metal shell by LED light bar.
Further, the heat dissipation cavity is uniformly arranged on reflector plate surrounding.
Further, the heat emission hole is arranged on the metal shell between LED light bar.
Compared with prior art, the beneficial effects of the utility model are：
By offering fresh air inlet in metal shell side, heat dissipation cavity is provided between reflector plate and metal shell, with
And it is fixedly connected with discharge pipe in side of the metal shell away from fresh air inlet and is installed with radiating in the discharge pipe other end
Fan, it can be reached by the hot-air inside lasting extraction heat dissipation cavity to the lasting radiating inside reflector plate.
