The first refraction surface receives light discharging from the light source while refracting the same to form a first refracting light, the upper part of the first refraction surface further comprising a refracting structure for refracting the light emitted from the light source. The second refraction surface receives and refracts the first refracting light to form a discharging light being emitted out of the light source package structure. Wherein, an included angle is formed between the normal vector of a portion of the second refraction surface and the central axis of the light source package structure. It is noted that the aforesaid package structure can be used in various packaging for improving refraction.

Abstract: A composite optical-dividing component receives a light beam. There are mixed-bands in the light beam. The composite optical-dividing component includes a first optical-patch and a second optical-patch. The first optical-patch has multiple micro-structural lenses in an identical shape. Each micro-structural lens receives the light beam and generates a deflecting light in some degrees of condense. The second optical patch has multiple polygonal structures. Some polygonal structures are periodic and provide the function of deflection in order to receive the deflecting light and then separate multiple bands from the beam. In accordance with wavelengths in multiple bands, the bands are emitted to a target area (RGB) in a plane, respectively. Another part of the polygonal structures has the capability of light refraction, which receives the deflecting light and deflects and the rest of the bands in the beam. And it is emitted to a target area (W) in a plane.
