Patent number: 10863599Abstract: A lighting device includes a first string of light emitting diodes (LEDs) configured to emit a warm white light having a warm Correlated Color Temperature (CCT). The lighting device further includes a second string of LEDs configured to emit a cool white light having a cool CCT. The lighting device also includes green light LEDs that emit a green light. A flux of the green light is controlled based on a flux of the cool white light or a flux of the warm white light. The flux of the warm white light and the flux of the cool white light change proportionally with respect to each other.Type: GrantFiled: November 7, 2019Date of Patent: December 8, 2020Assignee: SIGNIFY HOLDING B.V.Inventors: Raymond George Janik, Russell Scott Trask, Christopher Bohler

Patent number: 7686477Abstract: An illuminated sign (88) includes a flexible electrical power cord (100) including first and second parallel conductors (112, 114) surroundingly contained within an insulating sheath defining a constant separation distance between the parallel conductors (112, 114). A plurality of light emitting diode (LED) devices (102) are affixed to the cord (100). Each LED device (102) includes an LED (104) having a positive lead (130P) electrically communicating with the first parallel conductor (112) and a negative lead (130P) electrically communicating with the second parallel conductor (114). A stencil (92) defines a selected shape, and the electrical cord (100) is arranged on the stencil (92). Power conditioning electronics (210, 220) disposed away from the stencil (92) electrically communicate with the first and second parallel conductors (112, 114) of the electrical power cord (100).

Publication number: 20070267976Abstract: A light source (10) comprises a light engine (16), a base (24), a power conversion circuit (30) and an enclosure (22). The light engine (16) comprises at least one LED (12) disposed on a platform (14). The platform (14) is adapted to directly mate with the base (24) which a standard incandescent bulb light base. Phosphor (44) receives the light generated by the at least one LED (12) and converts it to visible light. The enclosure (22) has a shape of a standard incandescent lamp.Type: ApplicationFiled: May 5, 2004Publication date: November 22, 2007Inventors: Christopher Bohler, Boris Kolodin, Emil Radkov, Srinath Aanegola, Shanton Weaver, James Petroski, Zena Brown

Publication number: 20060176187Abstract: The inventive dummy load is mounted on the input power cables of a traffic signal while managing the heat load generated by either a resistive and/or capacitive load. Using the inventive dummy load, there is no thermal path back to the light emitting diode (LED) board. The inventive dummy load may be easly installed, removed, or replaced. The dummy load can be retrofit to adapt to a new controller, either by adding to or replacing the dummy load after initial installation or by removing part or all of the dummy load. There is no need to breach the sealed lamp to adjust the dummy load. Thus, field-adjustments can be made. Further, the number of parts required to manufacture lamps for a variety of retrofit applications are reduced, which in turn reduces the cost and complexity of the lamp.Type: ApplicationFiled: January 26, 2005Publication date: August 10, 2006Inventors: Christopher Bohler, Louis Brunet
