20140084809 | VARIABLE-BEAM LIGHT SOURCE AND RELATED METHODS - Light sources with arrangements of multiple LEDs (or other light-emitting devices) disposed at or near the focus of a reflecting optic and controllable individually or in groups facilitate varying the angular distribution of the light beam (e.g., the beam divergence) via the drive currents supplied to the LEDs. | 03-27-2014 |
20140217896 | METHOD AND DEVICE FOR REMOTE SENSING AND CONTROL OF LED LIGHTS - A control system is disclosed for determining an actual temperature of a light emitting diode. The control system uses conductor that supply power to the light emitting diode to supply a pulse to the light emitting diode. The pulse is determined along with a reaction caused by the pulse and the information gained is used in determination of the light emitting diode die temperature which can then be used in controlling current to the light emitting diode to control the temperature of the light emitting diode. | 08-07-2014 |
20150009677 | VARIABLE-BEAM LIGHT SOURCE AND RELATED METHODS - Light sources with arrangements of multiple LEDs (or other light-emitting devices) disposed at or near the focus of a reflecting optic having multiple segments facilitate varying the angular distribution of the light beam (e.g., the beam divergence) via the drive currents supplied to the LEDs. | 01-08-2015 |
20150143773 | RECESSED CAN DOWNLIGHT RETROFIT ILLUMINATION DEVICE - In various embodiments, an illumination device includes driver and LED lighting modules collectively sized to fit within a recessed-can lighting fixture constructed for use with incandescent or halogen bulbs, thereby facilitating LED changeover without removal and replacement of the fixture. | 05-28-2015 |
20150354781 | LIGHT SOURCE FOR UNIFORM ILLUMINATION OF AN AREA - A light source (e.g., a linear LED array or other light-emitting devices) may be coupled with multiple reflectors for providing uniform illumination on a target surface. | 12-10-2015 |
20150379594 | LIGHTING AUDIT AND LED LAMP RETROFIT - Embodiments of the invention provide systems and techniques for analyzing an existing light fixture in its installed environment and, based on the sensed location of the light and its environmental illumination pattern, identifying at least one LED retrofit fixture that may be used to replace the existing light fixture. | 12-31-2015 |
20160066386 | METHOD AND DEVICE FOR REMOTE SENSING AND CONTROL OF LED LIGHTS - Thermally managing at least one light-emitting diode (LED) receiving an operating current and/or an operating voltage and being operable at an operating temperature includes determining a current thermal operating point of the LED, obtaining a thermal operating range of the LED, and calculating a new operating point of the LED based on the current thermal operating point and the thermal operating range, wherein the new operating point is within the thermal operating range. A control signal is generated that adjusts power delivered to the LED to cause the LED to operate at the new operating point. Detection of the operating temperature of the LED may be based on the magnitude of a current pulse superimposed on the operating current provided to the LED and the magnitude of the voltage pulse across the LED resulting from the applied current pulse superimposed on the operating current. | 03-03-2016 |
20160097511 | LIGHT SOURCE FOR UNIFORM ILLUMINATION OF A SURFACE - Devices and methods for uniform illumination of a target surface are disclosed. A device assembly has a light source configured to be coupled to a mounting surface, and at least one reflector. The reflector is configured to be coupled to at least one of the light source or the mounting surface, and interposed between the light source and the mounting surface, the reflector having a reflective surface area and a plurality of curved reflective segments. The reflector is shaped and arranged relative to the light source such that the reflector directly intercepts and reflects a portion of light emitted by the light source to the target surface to thereby cause substantially uniform illumination of the target surface. The target surface has a surface area that is greater than the reflective surface area of the at least one reflector. | 04-07-2016 |
