Patent number: 6805458Abstract: A showerhead (802, 804) or faucet (12, 602, 702) includes a water outlet (16, 606, 706, 802) for emitting a water flow (22, 610, 710) and a handle (18, 20, 604, 704, 830) for controlling the water flow (22, 610, 770). At least one LED (42, 242, 342, 442, 542, 544, 546, 624, 658, 730, 810) is arranged on or in the showerhead (802, 804) or faucet (12, 602, 702) and viewable by an associated user thereof. A light-transmissive encapsulant (630, 660, 732) seals the at least one LED (42, 242, 342, 442, 542, 544, 546, 624, 658, 730, 810) and transmits light produced by the at least one LED (42, 242, 342, 442, 542, 544, 546, 624, 658, 730, 810) to the associated user. A controller (550) produces a controller output for controlling the LED light emission responsive to at least one of a water flow rate, a water flow temperature, an ambient light level, and a position of the handle (18, 20, 604, 704, 830).Type: GrantFiled: August 15, 2002Date of Patent: October 19, 2004Assignee: GELcore LLCInventors: Robert J. Schindler, Srianath K. Aanegola, Greg E. Burkholder, Frank P. Dornauer, Mitchell J. Hart, Kerry D. Moore, James T. Petroski, Tomislav J. Stimac

Patent number: 6799864Abstract: A light module includes a light emitting diode assembly defining a front side light emitting diode array and a rear side. The rear side is in thermal communication with a thermally conductive spreader, and a thermally conductive core is in thermal communication with the conductive spreader. The thermally conductive core includes an electrical conductor in operative communication with the front side light emitting diode array, and a plurality of appendages disposed about the thermally conductive core such that they are in thermal communication with the conductive spreader.Type: GrantFiled: May 24, 2002Date of Patent: October 5, 2004Assignee: GELcore LLCInventors: Christopher L. Bohler, Anthony D. Pollard, Greg E. Burkholder, James T. Petroski, Mathew L. Sommers, Robert F. Karlicek, Jr., Stanton E. Weaver, Jr., Charles A. Becker

Patent number: 6787999Abstract: A lamp (10) includes an optics module (12) and an electronics module (14, 60, 70). The optics module (10) includes a plurality of LEDs (76) arranged on a printed circuit board (18) and having a plurality of input leads, and a heat sink (22) having a conduit (40) for the input leads. The plurality of LEDs (16) thermally communicate with the heat sink (22). The electronics module (14, 60, 70) is adapted to power the plurality of LEDs (16) through the input leads. The electronics module (14, 60, 70) has a first end (52) adapted to rigidly connect with the heat sink (22), and a selected electrical connector (50, 62, 72) arranged on a second end for receiving electrical power. The electronics module (14, 60, 70) further houses circuitry (80) arranged therewithin for adapting the received electrical power (82) to drive the LEDs (16).Type: GrantFiled: October 3, 2002Date of Patent: September 7, 2004Assignee: GELcore, LLCInventors: Tomislav J. Stimac, James T. Petroski, Robert J. Schindler, Greg E. Burkholder
