An LED lamp that can take the place of incandescent lamps. An elevated light source is positioned above a screw-type base. A first plurality of LEDs is connected in a series on one side of a flat substrate and a second plurality of LEDs, equal in number to the first, is connected in series on an opposite side of the substrate. Each LED of the first and second plurality of LEDs is mounted proximate a heat sink and a drive circuit is provided for the LEDs, with the drive circuit being located proximate and electrically connected to the screw base.

LED lamp

A method of forming a light bulb core, and a light bulb or lamp incorporating the core. The method includes forming a heat sink having at least six working facets located equally on opposite sides of a central plane, and then mounting a light source on each of the working facets. The light sources are mounted on circuit boards, each circuit board corresponding to a respective one of the working facets. The boards are then applied to respective working facets. The bulb is composed of a screw base, an external heat sink mounted in the screw base, and the light bulb core mounted in and extending from the external heat sink. The light source comprises a plurality of light emitting diodes.

High intensity LED replacement of incandescent lamps

An LED lamp for replacement of directional incandescent lamps. The lamp comprises a screw base, a plurality of LEDs located in a first position, and a driver for the LEDs located in a second position separate from the first position. A lamp housing is secured to the screw base, with the LEDs and the driver being located in the lamp housing. A heat spreader is mounted in the lamp housing in proximity to the LEDs to remove heat therefrom. The heat spreader can also remove heat from the driver, or the driver can be located in proximity to the screw base and in thermal connection therewith so that heat is transmitted through the screw base.

Multiple films of red-green-blue (RGB) luminescent silicon nanoparticles are integrated in a cascade configuration as a top coating in an ultraviolet/blue light emitting diode (LED) to convert it to a white LED. The configuration of RGB luminescent silicon nanoparticle films harnesses the short wavelength portion of the light emitted from the UV/blue LED while transmitting efficiently the longer wavelength portion. The configuration also reduces damaging heat and/or ultraviolet effects to both the device and to humans.

The invention disclosed herein is a dynamic dummy load to allow a phase control dimmer to be used with LED lighting. The invention includes providing a dynamic dummy load to provide a load to the dimmer when the LED electronics do not provide sufficient load due to start up issues or ringing in the circuit, the dynamic dummy load providing a reduced flow of current when the LED and its converter electronics provide sufficient current draw from the dimmer. The system generally includes a power source electrically connected to a phase control dimmer, the phase control dimmer electrically connected to converter circuitry to convert the AC power output of the dimmer to DC power output for powering the LED lighting, a dynamic dummy load electrically connected in parallel with the converter circuitry, the dummy load varying its current draw in response to operation of the converter circuitry.

Dimming circuit for LED lighting device with means for holding TRIAC in conduction
