摘要： A light emitting diode contains a light emitting diode chip and a light directing structure disposed thereon. The light directing structure has a pair of connected hemi-ellipsoids and an interface interposed therebetween. Each hemi-ellipsoid comprises a bottom surface in a shape of an incomplete ellipse and an ellipsoidal surface connected to the bottom surface and the interface, wherein the largest vertical distance from the ellipsoidal surface to the bottom surface is longer than a height of the interface. The bottom surface has a major axis and a minor axis intersected to define a center, wherein the interface is connected to the minor axis.

摘要： A diffuser used in a backlight module including a plurality of light sources is disclosed. The diffuser according to the present invention makes a uniform light output. The diffuser includes a transparent substrate and a plurality of optical structures. The transparent substrate has an entrance surface and an exit surface. The plurality of optical structures is disposed on the exit surface, each optical structure is dented from the exit surface to the interior of the transparent substrate and forms a refractive convex within the transparent substrate, and each refractive convex corresponds to one of the plurality of the light sources. The maximum value of the included angle between the tangent to the refractive convex edge and the normal to the exit surface is smaller than 30 degrees, such that an incident light ray from the light sources refracts and deviates from the normal to the refractive convex through the refractive convex.

摘要： A white-light emitting device comprises a substrate, a short wavelength light source, a protective layer, a first structure, and a second structure. The short wavelength light source is disposed on the substrate for generating a first light, and the protective layer covering the short wavelength light source is pervious to the first light. The first structure is disposed on the protective layer for generating a second light, in which the first structure includes a first quantum well and a transmission layer. The second structure is disposed on the first structure for generating a third light. Finally, the first light, the second light, and the third light are mixed to generate a white light.
