Abstract: 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.

Abstract: 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.

Abstract: An LED display lamp for generating an illumination of a pattern replicating a recognizable shape. The lamp has a base and an elevated light source above the base comprising a group of LEDs connected in series and mounted on one side of a generally flat substrate. A drive circuit drives the LEDs, with the drive circuit being electrically connected to the base. A plurality of the groups of LEDs is employed, depending on the recognizable shape being replicated. Multiple patterns can be separately mounted on each side of the substrate, with the patterns on each side being the same or unrelated to one another.

Abstract: 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.
