Abstract: An optical sheet is disclosed in the present invention and comprises a substrate, a reflective layer and a plurality of pixels. The reflective layer is disposed on the substrate. The pixels are composed of several quantum dot fluorescent powders respectively and arrayed on the reflective layer. In addition, a method for manufacturing the above optical sheet, a light emitting diodes module and a display using the above optical sheet are also disclosed in the present invention.

Abstract: A package structure applied for method for a solid-state lighting apparatus is disclosed in the present invention and at least comprises a frame, a light emitting member, an encapsulant and a plurality of fluorescent powders. The light emitting member is disposed in the frame. The encapsulant is provided to fill the frame for packing the light emitting member therein, and the fluorescent powders are dispersed in the encapsulant. Furthermore, there is a plurality of scattering particles doped into the encapsulant.

Abstract: Disclosed are compositions and synthetic methods of phosphors that can be efficiently excited by blue light. The wavelength of the blue light is between 400 nm to 480 nm. The phosphors contain garnet fluorescent material activated with cerium, which contain Ba, Y, Tb, Lu, Sc, La, Gd, Sm, or combinations thereof, and Al, Ga, In, or combinations thereof. In addition, the phosphors are easily and quickly prepared in a large amount. The phosphors have high thermal stability and high emission intensity, therefore, being high of value in industry for utilization.

Abstract: A solid state lighting luminaire, which comprises a solid state light source, an encapsulated structure, and a first phosphor, is provided. The encapsulated structure encapsulates the solid state light source and has an outside illuminating surface. The first phosphor is patterned to cover a portion of the outside illuminating surface for down-converting the illumination from the solid state light source.
