  • Patent number: 8965596
    Abstract: A solar string includes first and second solar modules coupled to first and second filters by an electric transmission line. The second solar module includes a solar panel including a plurality of photovoltaic cells configured to convert photon energy to electrical energy. A processor is coupled to the solar panel and is in communication with the first solar module. The processor is configured to monitor an output of the solar panel and to transmit a status signal including an environmental condition of the second solar module to the first solar module by way of the electric transmission line. The first and second filters are configured to pass electrical power to a central inverter of a solar array in which the solar string is disposed and to prevent the status signal transmitted from the second solar module to the first solar module from being transmitted to the central inverter.

  • Patent number: 7367708
    Abstract: A direct type backlight unit includes a metal housing having a base, at least one metal supporting pin and a buffer element. The metal supporting pin is formed integrally on the base and protrudes upwardly therefrom for supporting an optical film disposed upon the backlight unit, and the buffer element is disposed between the metal supporting pin and the optical film so as to prevent the metal supporting pin from damaging the optical film.

  • Patent number: 6874900
    Abstract: A panel light source device comprises light sources, a light guide, and a reflector. The light guide defines a bottom surface and a top surface, and comprises grooves disposed on the bottom surface for receiving the light sources and pairs of first inclined surfaces disposed on the top surface and corresponding to the groove. The grooves and the first inclined surfaces cooperate with each other to transmit the light from the light source into the light guide. The reflector is disposed on the bottom surface of the light guide and covers the light source.
