LED backlight module
First Claim
1. A light-emitting diode (LED) backlight module comprising:
- a diffusion plate;
at least an optical device provided underneath the diffusion plate and having a first reflection surface;
at least a light-emitting diode provided underneath the at least an optical device, for emitting light to the first reflection surface where first reflection of the light is performed; and
a second reflection surface provided underneath the at least a light-emitting diode, for receiving the light of the first reflection and performing second reflection of the received light.

Abstract
A LED backlight module including a diffusion plate, at least an optical devices, at least a light-emitting diode and a second reflection surface is provided. The optical device is provided underneath the diffusion plate and has a first reflection surface. The light-emitting diode is provided underneath the optical device, for emitting light to the first reflection surface where first reflection of the light is performed. The second reflection surface is provided underneath the light-emitting diode, for receiving the light of the first reflection and performing second reflection of the received light. By controlling light paths of LED with the optical devices, light emitted from LED may be leaded to a specific direction instead of directly emitting from a front surface of LED, so as to achieve the performance of color-mixing and uniform distribution.
