Abstract: A light concentrating module includes an optical film having a light incident surface and a light outgoing surface facing the light incident surface, an optical wedge element having a first surface, a second surface facing the first surface and having an angle with respect to the first surface and a third surface adjacent to the first and second surfaces, and at least one photoelectric chip disposed near the third surface. Light from a light source penetrates the optical film, and the light enters the first surface of the optical wedge element by an appropriate incident angle and has total reflection between the first and second surfaces, whereby the light propagates in the optical wedge element, and the light leaves the optical wedge element from the third surface and is received by the photoelectric chip.

Abstract: A light concentrating module includes an optical film having a light incident surface and a light outgoing surface facing the light incident surface, an optical wedge plate having a first surface, a second surface facing the first surface and having an angle with respect to the first surface and a third surface adjacent to the first and second surfaces, and at least one photoelectric chip disposed near the third surface. Light from a light source penetrates the optical film, and the light enters the first surface of the optical wedge by an appropriate incident angle and has total reflection between the first and second surfaces, whereby the light propagates in the optical wedge, and the light leaves the optical wedge from the third surface and is received by the photoelectric chip.

Abstract: A flexible light emitting device including at least one light source and a flexible light guide is provided. The flexible light guide has at least one light emitting surface and at least one light incident surface. Moreover, micro-structures are located on at least one surface of the flexible light guide except the light incident surface. The light source is disposed beside the light incident surface of the flexible light guide. When the light of the light source is incident into the flexible light guide, the total reflection would be destroyed due to the micro-structures, and thus the light could emit out of the flexible light guide from the light emitting surface.

Abstract: A passive optical device includes a first substrate, a second substrate, a stabilized liquid crystal (LC) layer and a surface micro-structure layer. The stabilized LC layer is disposed between the first substrate and the second substrate and has a polarization beam-splitting function via an aligning direction of liquid crystal molecules. The surface micro-structure layer is disposed on an exterior surface of at least one of the first substrate and the second substrate and used to produce a light-collecting effect.

Abstract: A light source apparatus including a light emitting module and a reflection microstructure layer is provided. The light emitting module emits a light. The reflection microstructure layer is disposed at the base of the light source apparatus and reflects an incident light emitted by the light emitting module in substantially a same direction.

Abstract: An optical element is provided in the present invention, which comprises an element body and a plurality of microlens elements. The element body has a first surface disposed thereon. The plural microlens elements are arranged two-dimensionally on the first surface. The size and shape for each microlens elements may be different from each other and the arrangement for the plural microlens elements on the first surface may be random and arbitrary so that the optical element of the present invention are capable of performing light diffusion and light-redirecting effects without generating interference fringes.

Abstract: A light guide plate with a light emitting surface, a bottom surface and at least one light incident surface being connected with the light emitting surface and the bottom surface is provided. The light guide plate is a superposition of a plurality of layers substantially parallel to the light emitting surface. A plurality of stripe-shaped light-controlling structures are formed on the light emitting surface and a plurality of light-reflecting structures are formed on the bottom surface. The light guide plate provides a surface light source with high brightness and excellent uniformity in a direction perpendicular to the light emitting surface.
