    Abstract: A solar simulator for testing photovoltaic cells is disclosed herein. The solar simulator includes a housing having an opening through which light is emitted. The solar simulator employs a plurality of concave cylindrical mirrors and a plurality of flat mirrors that reflect and redirect images of an illuminated light source such that an observer at a target area outside the housing will perceive multiple instances of the illuminated light source. The housing also contains a flat top cover mirror and a flat bottom cover mirror that function to reflect additional light through the opening and toward the target area.

    Abstract: A hollow edge-type backlight module with a light-emitting array and a display apparatus containing the same are disclosed. The hollow edge-type backlight module mainly utilizes a hollow reflection structure to replace a light-guide plate structure, and forms a light-emitting unit by collaborating with an edge-type light source, and forms a light-emitting array by appending together a plurality of light-emitting units. The reflection structure of each light-emitting unit has a horizontal surface and a reflective surface connected to the horizontal surface, wherein there is an angle included between the reflective surface and a surface extended from the horizontal surface, and the light source is disposed adjacent to the horizontal surface. A diffuser of the hollow edge-type backlight module is disposed above the reflective surface and the horizontal surface, and the diffuser, the light source, the horizontal surface and the reflective surface define at least one air cavity.

  • Patent number: 8192053
    Abstract: A high-intensity light source is formed by a micro array of a semiconductor light source such as a LEDs, laser diodes, or VCSEL placed densely on a liquid or gas cooled thermally conductive substrate. The semiconductor devices are typically attached by a joining process to electrically conductive patterns on the substrate, and driven by a microprocessor controlled power supply. An optic element is placed over the micro array to achieve improved directionality, intensity, and/or spectral purity of the output beam. The light module may be used for such processes as, for example, fluorescence, inspection and measurement, photopolymerzation, ionization, sterilization, debris removal, and other photochemical processes.
