20090035885 | METHODS OF FORMING LIGHT-EMITTING STRUCTURES - Methods of forming light-emitting structures, as well as related devices and/or systems are described. In some cases, the methods utilize a layer transfer and/or layer separation step(s) used to form such structures. | 02-05-2009 |
20090157567 | LED LIGHTING SYSTEM - A method for optimizing an LED lighting system cost includes steps of determining LED costs, power source costs, and total costs associated with a plurality of LED quantities, and identifying a lowest total cost as an optimal cost. A LED lighting system includes an LED operated by a constant-current driver at less than its maximum current capacity. A programmable controller including a feedback routine is used to compensate for intensity drift as an LED ages. Other embodiments of LED lighting systems include multiple LEDs producing light having various spectrums to optimize the lighting system efficiency and the effectiveness. A charge controller including an MPPT routine is advantageously employed with a LED lighting system powered by a limited-capacity power source. | 06-18-2009 |
20090236506 | LIGHT-EMITTING DEVICE ON-WAFER TEST SYSTEMS AND METHODS - On-wafer test systems and methods for light-emitting devices, such as light-emitting diodes (LEDs), are provided. The test system may be designed, for example, to characterize the light output from the LED die (e.g., power in Lumens). | 09-24-2009 |
20090284161 | LIGHT-EMITTING DEVICES - Light-emitting devices, and related assemblies, systems and methods are described. Specifically, at least some of the embodiments relate to light-emitting devices including proximate switching element(s). The switching element(s) control the current, or power, supplied to the light-emitting devices. | 11-19-2009 |
20100260945 | SYSTEM AND METHODS FOR OPTICAL CURING USING A REFLECTOR - Systems and methods for curing a curable coating with electromagnetic radiation are provided. The system may include a reflector having a focusing reflective surface, a source focal region, and an object focal region. An array of UV LEDs may be positioned within the source focal region to emit an electromagnetic radiation toward the focusing reflective surface. The focusing reflective surface can reflect light emitted by the array of UV LEDs toward the curing surface located within the object focal region of the reflector. | 10-14-2010 |
20110121703 | THERMAL MANAGEMENT SYSTEMS FOR LIGHT EMITTING DEVICES AND SYSTEMS - One or more embodiments presented herein include a light emitting system and/or device that can include a thermal management system. The thermal management system can provide for transport and/or dissipation of heat generated by a light emitting device. | 05-26-2011 |
20110240961 | LIGHT-EMITTING DEVICES FOR LIQUID CRYSTAL DISPLAYS - Light emitting devices, and related components, processes, systems and methods are disclosed. | 10-06-2011 |
20120195068 | LIGHT-EMITTING DEVICES FOR LIQUID CRYSTAL DISPLAYS - A lighting system includes a panel having an edge, the edge having a thickness defined between a front surface of the panel and a back surface of the panel, the panel configured to propagate light therein. The lighting system further includes a first light emitting diode (LED) light source and a second LED light source disposed in serrated arrangement along the edge of the panel so that light emitted from respective light emitting surfaces of the light sources impinges on the edge of the panel and enters the panel through the edge and so that the light emitting surfaces lie in respective planes that are not parallel. | 08-02-2012 |
