20090322224 | STARTING AID FOR HID LAMP - An arc discharge light source ( | 12-31-2009 |
20090322225 | Starting Aid for HID Lamp - A high-intensity discharge lamp includes a discharge vessel made of an insulator, and a cathode and anode. A V-shaped gap is provided between the anode and a first region of the vessel directly adjacent to where the anode separates from an interior surface of the vessel. A secondary cathode is provided on an exterior surface of the vessel at the first region, where the secondary cathode is positioned so that the V-shaped gap and the first region are between the secondary cathode and the anode. An electric field at the first region produces a dielectric barrier discharge (DBD) which generates ultraviolet (UV) and vacuum ultraviolet VUV photons that impinge on the cathode and initiate a breakdown between the cathode and anode. | 12-31-2009 |
20110043119 | Method of Starting an HID Lamp and Ballast Incorporating Same - There is provided herein a method for starting a high intensity discharge lamp and a ballast incorporating the same. In a preferred embodiment, the method comprises the steps of: (a) obtaining a cumulative probability function of breakdown times, P(t), for the lamp at a voltage, V; (b) determining a minimum pulse length, T | 02-24-2011 |
20120062112 | APPARATUS, SYSTEM, AND METHOD OF CONTROLLING IGNITION TIMING OF A HID LAMP USING A THIRD ELECTRODE - A high-intensity discharge (HID) lamp comprising a discharge vessel including a first and a second end region and defining an arc chamber containing an arc generating medium, a cathode and an anode in the first and the second end regions of the discharge vessel, respectively, the cathode and the anode each comprising a terminal end disposed within the arc chamber and separated by an arc gap, and an electrically conductive starting aid configured to initiate a dielectric barrier discharge (DBD) with the anode at or after a voltage across the first and second electrodes reaches an open circuit value. A ballast may control power provided to the HID lamp. | 03-15-2012 |
20120306380 | MULTIMODE COLOR TUNABLE LIGHT SOURCE AND DAYLIGHTING SYSTEM - Described herein are day lighting systems that utilize a combination of at least one natural light source with at least one multimode artificial light source. Also disclosed are methods for designing and operating such systems. | 12-06-2012 |
20120306381 | MULTIMODE COLOR TUNABLE LIGHT SOURCE - Described herein are ambient lighting devices, methods, and systems that utilize at least one multimode artificial ambient light source, a control unit, and a remote image sensor. The control unit couples to at least one artificial ambient light source and is configured to output at least one control signal to the at least one artificial ambient light source. The at least one multimode artificial ambient light source is configured to output light of varying color and color temperature in response to said at least one control signal. The remote image sensor couples to the at least one control unit and is configured to detect at least one color and intensity characteristic and output an output signal to the at least one control unit, based on said color and intensity characteristic detected. | 12-06-2012 |
20130002144 | MULTIMODE COLOR TUNABLE LIGHT SOURCE AND DAYLIGHTING SYSTEM - Described herein are day lighting systems that utilize a combination of at least one natural light source with at least one multimode artificial light source. Also disclosed are methods for designing and operating such systems. | 01-03-2013 |
20140232292 | ILLUMINATION TECHNIQUES AND DEVICES - Illumination techniques and related devices are disclosed. In some cases, a lighting device configured as described herein may include a front luminaire configured to emit white light and a back luminaire configured to emit colored light. The lighting device can be operatively coupled with controller circuitry programmed or otherwise configured, for example, with one or more algorithms which control the light output of the front and/or back luminaire so as to provide tunability. In some cases, device output may be controlled so as to: (1) simulate lighting conditions/patterns corresponding to the daytime/nighttime on Earth; (2) support/alter physiological processes; and/or (3) provide a specific ambient lighting for a given space. In some instances, a system of multiple such lighting devices can be provided, and in some cases, communication between constituent lighting devices may be provided. In some instances, the lighting device may be mountable as a sconce or other lighting fixture. | 08-21-2014 |
