  • Smart integrated semiconductor light emitting system including nitride based light emitting diodes (LED) and application specific integrated circuits (ASIC)
    Patent number: 8933467
    Abstract: A light emitting diode (LED) system includes a substrate, an application specific integrated circuit (ASIC), and at least one light emitting diode (LED) that includes a Group-III nitride based material such as GaN, InGaN, AlGaN, AlInGaN or other (Ga, In or Al) N-based materials. The light emitting diode (LED) system can also include a polymer lens, and a phosphor layer on the lens or light emitting diode (LED) for producing white light. In addition, multiple light emitting diodes (LEDs) can be mounted on the substrate, and can have different colors for smart color control lighting. The substrate and the application specific integrated circuit (ASIC) are configured to provide an integrated LED circuit having smart functionality. In addition, the substrate is configured to compliment and expand the functions of the application specific integrated circuit (ASIC), and can also include built in integrated circuits for performing additional electrical functions.

  • LED LAMP
    Publication number: 20140175966
    Abstract: A lamp comprises an LED light source for emitting light. A combined heat sink and reflector is thermally coupled to the LED light source. The heat sink and reflector comprise an internal surface for reflecting the light and an exterior surface. The internal surface and the external surface are uncovered such that heat is dissipated from the interior surface and the exterior surface.
