Abstract
A light source inside a back light module comprising a red light-emitting diode, a green light-emitting diode, a blue light-emitting diode, a diffusion device, some supporting elements and reflectors is provided. The red, green and blue light-emitting diodes mount on a holder. The diffusion device is set up over the holder. The diffusion device comprises a transparent body and a plurality of fine particles distributed within the transparent body. The supporting elements are positioned between the diffusion device and the holder. The reflectors are attached to the surface on each side of the holder and the diffusion device. Red, green and blue lights from various light-emitting diodes are thoroughly mixed inside the diffusion device to form a uniform white light.

8. A light source inside a back light module, comprising:
-
at least a first light-emitting diode having a first optical axis;
at least a second light-emitting diode having a second optical axis;
at least a third light-emitting diode having a third optical axis, wherein the first optical axis, the second optical axis and the third optical axis are not parallel to one another;
a diffusion device set up over the first light-emitting diode, the second light-emitting diode and the third light-emitting diode such that the first optical axis, the second optical axis and the third optical axis all converge towards the diffusion device; and
reflectors attached to the surface of the diffusion device such that the uncovered portion of the diffusion device constitute a light-incident surface and a light-emitting surface. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
