Abstract: A circuit includes an input and an output, and an electronic light generator drive portion that is coupled to the input and drives the output. In one configuration, the circuit includes a further portion that is coupled to the input and that tunes a resonance at the input to a first frequency, the further portion having an additional portion with a resonance that is tuned to a second frequency different from the first frequency, and that effects damping of the first frequency at the input. In a different configuration, the drive portion includes an electronic switch coupled to the output of the circuit, and a further portion coupled to the input and having a phase tracking portion, the phase tracking portion tracking a phase of a signal at the input and producing a control signal that is used to control the electronic switch.

Abstract: The present light bulb uses electronic light generating sources and serves as a replacement for incandescent lamps or other lamps or so-called “light bulbs.” The light bulb is comprised of a plurality of individual light sources, such as light emitting diodes (LED's), capable of emitting white light or blue light or light of any other desired color. These light emitting elements are enclosed in an outer bulb housing that may include an optical tuning element and provided with the proper base for connection to a power source, e.g. a socket. The light bulb is characterized by a housing having a round top and a somewhat funnel-shaped side wall connected to the base. The side wall is constructed with the desired angle of taper in order to obtain the desired angle of dispersion of the light. The interior of the tapered portion is provided with a mirrored surface so as to reflect light in the interior of the bulb and thereby obtain a wide angle of dispersion.

Abstract: A device has an electrical connector, a radiation generator, and a flexible carrier with circuitry that is operatively coupled between the connector and the radiation generator. In response to electrical power received through the connector, the circuitry energizes the radiation generator, and the radiation generator emits radiation. In a different embodiment, a device has an electrical connector, a radiation generator, and a member with circuitry embedded therein. The circuitry is operatively coupled between the connector and the radiation generator. In response to electrical power received through the connector, the circuitry energizes the radiation generator, and the radiation generator emits radiation.

Abstract: A device has a plurality of light emitting diodes (LEDs), heat conducting structure that includes a heat pipe and that carries heat from the region of the LEDs to a further location spaced therefrom, and heat dissipating structure that accepts heat from the heat conducting structure at the further location and that discharges the heat externally of the device. In a different embodiment, a device has a radiation generator, a thermal spreader that receives heat emitted by the radiation generator, heat conducting structure that carries heat from the thermal spreader to a location spaced therefrom, and heat dissipating structure that accepts heat at the location from the heat conducting structure and that discharges the heat externally of the device.
