Patent number: 9730294Abstract: A lighting device with a drive device for dimming light-emitting diodes. The drive device comprises a dimming component that operates a switch in response to both a change in an input power signal and a system temperature. In one example, the dimming device can include a waveform generator that generates a signal with a waveform having levels that change in response to changes in temperature. The waveform defines the time during which the switch is open and closed, thereby determining the period of time the LEDs are energized. By operating the LEDs in this manner, the drive device effectively dims the LEDs to reduce the operating temperature and cool the LEDs.Type: GrantFiled: November 7, 2011Date of Patent: August 8, 2017Assignee: GE LIGHTING SOLUTIONS, LLCInventor: Bruce Richard Roberts

Patent number: 9332602Abstract: A system and apparatus including a light emitting diode (LED) driver provides an operating DC voltage to a plurality of LEDs connected in series (LED array) for providing illumination. A rectifier circuit and a filter are coupled to an AC power supply and provide a rectified and filtered DC source voltage to a transformerless voltage boost circuit, which provides the operating DC voltage to the LED array. A hysteretic self-oscillating circuit drives the transformerless voltage boost circuit at an oscillation frequency. A tap is connected between two LEDs in the LED array, which provides an auxiliary DC voltage, which is used to power the oscillating circuit and which eliminates the need for the LED driver to have a conventional transformer or auxiliary DC-DC power converter. The transformerless voltage boost circuit includes an inductor, a capacitor, a diode, and a switch wherein the switch is controlled by the oscillating circuit.Type: GrantFiled: December 12, 2013Date of Patent: May 3, 2016Assignee: GENEREAL ELECTRIC COMPANYInventors: Bruce Richard Roberts, Shahzil Rana
