20140247596 | LED PATTERN DISPLAY LAMP - 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. | 09-04-2014 |
20130083533 | High Intensity LED Replacement of Incandescent Lamps - 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. | 04-04-2013 |
20110229995 | Silicon Nanoparticle White Light Emitting Device - 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. | 09-22-2011 |
