  • LED lamp with reflector and multicolor adjuster
    Patent number: 6149283
    Abstract: A lighting device has a support that can be screwed into a standard 120 volt light socket. A ring with multiple, alternating color, circumferentially spaced LEDs, is connected to the support and a reflector is provided over the ring for reflecting light from the LEDs past the ring. A power supply circuit is connected to the LEDs for powering the LEDs to emit light. The light can be white if the LEDs are a combination of red, blue and green or other white-forming combinations, or the power circuit can selectively power subsets of the LEDs to produce and desired color. The same circuit can be used to vary the intensity of the light in the manner of a dimmer.
