The plug is locked in place by means of threaded screw heads, snug-fit, snap-on buttons or an elastic sleeve. Thus, the light emitting device can be easily replaced without any wire bonding. A plurality of the light unit can be sandwiched between the upper metal plate and the lower metal plate.Type: GrantFiled: April 15, 2005Date of Patent: October 23, 2007Inventor: Jiahn-Chang Wu

Patent number: 7153008Abstract: A LED lamp mounting assembly for use in motor vehicle lamps is described. The LED lamp mounting assembly connects a LED lamp to a pre-existing incandescent lamp socket in a motor vehicle. The LED lamp mounting assembly therefore allows a LED lamp to be operated from incandescent lamp hardware. In one embodiment, the LED lamp mounting assembled includes a LED lamp assembly, a heat sink, a cradle, printed circuit boards and an electrical connector. The electrical connector is insertable into the incandescent lamp socket and connects to the printed circuit boards. The printed circuit boards power the LED lamp assembly and the heat sink adsorbs excess heat created by the LED lamp assembly. The motor vehicle lamp becomes a LED lamp without any changes to the existing incandescent lamp hardware.Type: GrantFiled: August 18, 2004Date of Patent: December 26, 2006Assignee: Grote Industries, Inc.Inventors: William Dominic Grote, III, Kevin Scott Williams, Jay Frederick Koehler

Patent number: 6979097Abstract: The invention is a modular ambient lighting system for providing lighting to the interior of the building. The system features three separate modules: (1) a support module, (2) a power module, and (3) a light fixture body module. The support module provides an electrical connection to the building and structural connection to the ceiling of the building. An interchangeable power module fits into a recess or “foot print” in the support module. The power module includes the electrical components of the lighting system (e.g. ballast, transformer, emergency batteries, etc). An interchangeable light fixture body module houses the lamp that can be configured to deliver direct, indirect, or direct/indirect illumination. The interchangeable features of the modules offers superior flexibility because of the ease to reconfigure the electrical operation of the light system, the type illumination delivered, or the aesthetics of the light system.Type: GrantFiled: March 18, 2003Date of Patent: December 27, 2005Inventors: Thomas E. Elam, Timothy P. Scherf

Patent number: 6957906Abstract: A solid-state light source (10) that is compatible with the existing sockets normally reserved for filamented lamps (100). The solid-state light source (10) comprises a hollow base (12) formed to mechanically and electrically adapt to an existing socket normally reserved for lamps (100). A sub-assembly (14) is adapted to cooperate with and fit into the hollow base (12). The sub-assembly (14) comprises a circuit board (16) with a plurality of solid-state light sources (18) mechanically and electrically connected to one side (20) of the circuit board. Two electrical contacts (22, 24) are positioned on the other side (26) of the circuit board for connection to an electrical circuit. A light pipe (28) covers the plurality of light sources (18) and extends away therefrom to a terminal end (30).Type: GrantFiled: November 30, 2004Date of Patent: October 25, 2005Assignee: Osram Sylvania Inc.Inventors: Charles M.
