Abstract: A white light LED assembly has at least two kinds of light-emitting units. The units can be a white light-emitting unit composed of red, green and blue LEDs, a white light-emitting unit composed of a blue and yellowish-green LEDs, a white light-emitting unit composed of a blue LED and yellow phosphor, or a white light-emitting units composed of UV LED and red, green and blue phosphors. The white light LED assembly according to the present invention has satisfactory efficiency and color rendering property as well as flexible phosphor usage.

Abstract: A BLU module has a plurality of BLUs assembled together. Each of the BLUs includes a light guide, a light source structure adjacent to the light guide, and a heat conduction member contacting the light source structure. The light guide has a light-emitting surface arranged on a top thereof and a bottom surface opposing the light-emitting surface, the light-emitting surface being larger than the bottom surface so that that light guide defines a first cavity formed therebetween. The light source structure is received in the first cavity. The light guide in two adjacent BLUs of the module defines a second cavity opposite the first cavity for receiving an adjacent heat conduction member of a prior adjacent light guide. The module is provided with a variable size with the BLUs assembled together to meet requirements.
