Abstract: A backlight module is provided. The backlight module has a reflective chamber and a light source. The reflective chamber includes a bottom reflector, a top reflector, at least a light entrance, and a plurality of light emitting openings disposed on the top reflector. The light source is disposed corresponding to the light entrance. The number of the light emitting openings per unit area in a region near the light source is less than the number of the light emitting openings per unit area in another region far from the light source.

Abstract: An LED light module of uniformly mixed light is provided. The LED light module has a plurality of shifted-disposed LED packages, arranged as a polygon, disposed on a substrate. Each of the shifted-disposed LED packages includes a base, and an LED die disposed aside from a center of the base. The light emitted from the shifted-disposed LED package is asymmetrically dispersed and is tilted to a predetermined direction. Therefore, the lights from the shifted-disposed LED packages are centralized and uniformly mixed as white light.

Abstract: A diffuser plate with higher light diffusion efficiency and brightness applied to backlight module of Liquid Crystal Display TV (LCD TV) for providing uniform light is disclosed. An optical lens with a diffusion layer is disposed on one side of the substrate. The diffusion layer is arranged above the optical lens for enhancing diffusion effect. The other side of the diffuser plate can be a plane or having a lens structure. By Lenticular lens, the homogeneity of emitted light is improved so as to reduce the amount of diffusion particles being added into the diffusion plate Therefore, the light transmission is increased and the brightness is enhanced. Meanwhile, ability of shielding lamps is considered and Moiré effect is eliminated. Moreover, the diffusion layer is co-extruded on surface of the Lenticular lens together with the substrate so that the device is easy to be produced.
