In order to achieve the above purpose, the utility model adopts the following technical scheme:

the energy-saving and low-consumption liquid crystal display television backlight module comprises a shell, a reflector, an LED light source, a diffusion plate, a brightness enhancement film and a diffusion film, wherein the reflector is fixedly arranged inside the shell, the LED light source is uniformly distributed and fixedly arranged on the surface of the reflector, the diffusion plate, the brightness enhancement film and the diffusion film are all arranged at an opening of the shell in an inserted manner, and the diffusion plate, the brightness enhancement film and the diffusion film are mutually attached and distributed from inside to outside.

Preferably, the periphery of the reflector is obliquely arranged, and the periphery of the reflector and the shell are hollowed out.

Preferably, the opening of the shell is provided with a slot, and the diffusion plate, the brightness enhancement film and the diffusion sheet are inserted into the opening of the shell through the slot.

Preferably, the bottom of the shell is fixedly provided with supporting legs which are obliquely arranged.

Preferably, the reflector adopts a ship-shaped structure.

Preferably, the surface of the diffusion plate is sprayed with fluorescent powder.

Preferably, the LED light source adopts an LED lamp bead.

Compared with the prior art, the utility model provides an energy-conserving low consumption LCD TV backlight unit possesses following beneficial effect:

1. the energy-saving and low-consumption liquid crystal television backlight module can enable light rays emitted by the LED light source to be softer through the diffusion plate, the brightness enhancement sheet and the diffusion sheet, so that the display effect of the energy-saving and low-consumption liquid crystal television liquid is guaranteed.

2. This energy-conserving low consumption LCD TV backlight unit, through the reflector panel that is equipped with, all be the slope setting around the reflector panel, and form the fretwork setting between the reflector panel and the shell all around, not only improved reflection of light effect, can eliminate the facula moreover.

The part that does not relate to in the device all is the same with prior art or can adopt prior art to realize, the utility model discloses can make the light that the LED light source sent softer to guarantee the display effect of energy-conserving low consumption LCD TV liquid.
