Publication number: 20080278092Abstract: Power control methods and apparatus in which a switching power supply provides power factor correction and an output voltage to a load via control of a single switch, without requiring any feedback information associated with the load. The single switch may be controlled without monitoring either the output voltage across the load or a current drawn by the load, and/or without regulating either the output voltage across the load or the current drawn by the load. The RMS value of an A.C. input voltage to the switching power supply may be varied via a conventional A.C. dimmer (e.g., using either a voltage amplitude or duty cycle control technique) to in turn control the output voltage. The switching power supply may comprise a flyback converter configuration, a buck converter configuration, or a boost converter configuration, and the load may comprise an LED-based light source.Type: ApplicationFiled: May 1, 2008Publication date: November 13, 2008Applicant: PHILIPS SOLID-STATE LIGHTING SOLUTIONS, INC.Inventors: Ihor Lys, Igor Shikh

Publication number: 20080164827Abstract: Methods and apparatus for simulating resistive loads, and facilitating series, parallel, and/or series-parallel connections of multiple loads to draw operating power. Current-to-voltage characteristics of loads are altered in a predetermined manner so as to facilitate a predictable and/or desirable behavior of multiple loads drawing power from a power source. Exemplary loads include LED-based light sources and LED-based lighting units. Altered current-to-voltage characteristics may cause a load to appear as a substantially linear or resistive element to the power source, at least over some operating range. In connections of multiple such loads, the voltage across each load is relatively more predictable. In one example, a series connection of multiple loads with altered current-to-voltage characteristics may be operated from a line voltage without requiring a transformer.Type: ApplicationFiled: August 9, 2007Publication date: July 10, 2008Applicant: Color Kinetics IncorporatedInventor: Ihor A.

Publication number: 20080122376Abstract: Methods and apparatus for controlling series-connected LEDs. Two or more LEDs are connected in series between a first node and a second node, wherein a series current flows between the nodes when an operating voltage is applied across the nodes. One or more controllable current paths are connected in parallel with at least a first LED for at least partially diverting the series current around at least the first LED. A controller monitors at least one parameter representative of the operating voltage, determines a maximum number of the series-connected LEDs that can be energized by the operating voltage, and controls the controllable current path(s) so as to increase an amount of the series current that is diverted around at least the first LED when the maximum number is less than a total number of all of the LEDs connected in series. In one example, the foregoing may be implemented as an integrated circuit package to provide a lighting apparatus suitable for automotive applications.Type: ApplicationFiled: November 9, 2007Publication date: May 29, 2008Applicant: Philips Solid-State Lighting SolutionsInventor: Ihor A.

Patent number: 7358706Abstract: Power factor correction control methods and apparatus based on knowing in advance some information relating to anticipated load conditions (e.g., a desired power to be provided to a load). Based on “feeding-forward” known information about anticipated load conditions, power factor correction control loop response is significantly improved, particularly in situations in which the load power traverses a wide range in a short time period (e.g., load full off to load full on, or vice versa). As a result of improved control loop stability, smaller circuit components may be employed based on more predictable expectations for signal values, thereby reducing the cost and/or size of the implemented circuits. In one example, a processor controls both a feed-forward power factor correction apparatus and a feed-forward power driver for an LED-based light source to provide an efficient source of radiation using significantly streamlined circuits having fewer components and smaller space requirements.Type: GrantFiled: March 14, 2005Date of Patent: April 15, 2008Assignee: Philips Solid-State Lighting Solutions, Inc.Inventor: Ihor A.

Patent number: 7352138Abstract: Methods and apparatus for providing power to devices via an A.C. power source, and for facilitating the use of LED-based light sources on A.C. power circuits that provide signals other than standard line voltages. In one example, LED-based light sources may be coupled to A.C. power circuits that are controlled by conventional dimmers (i.e., “A.C. dimmer circuits”). Hence, LED-based light sources may be conveniently substituted for other light sources (e.g., incandescent lights) in lighting environments employing conventional A.C. dimming devices and/or other control signals present on the A.C. power circuit. In yet other aspects, one or more parameters relating to the light generated by LED-based light sources (e.g., intensity, color, color temperature, temporal characteristics, etc.) may be conveniently controlled via operation of a conventional A.C. dimmer and/or other signals present on the A.C. power circuit.Type: GrantFiled: April 18, 2006Date of Patent: April 1, 2008Assignee: Philips Solid-State Lighting Solutions, Inc.Inventors: Ihor A.
