Patent application number | Description | Published |
20080233661 | Methods and Systems For Lithography Alignment - Methods and systems for lithographically exposing a substrate based on a curvature profile of the substrate. | 09-25-2008 |
20120113639 | LIGHT EMITTING DIODE DEVICE WITH EFFECTIVE HEAT DISSIPATION - The present disclosure relates to light emitting diode (LED) devices and methods for fabricating the same. An LED device includes a housing adapted to combine a heat sink with a vapor chamber to form an enclosed space interposed therebetween. The LED device includes light emitting diode modules attached to the housing adjacent to the vapor chamber. The vapor chamber is adapted to uniformly disperse heat generated from the LED modules within the enclosed space to form a uniform temperature field on the heat sink to thereby provide effective heat dissipation. | 05-10-2012 |
20120292655 | LIGHT EMITTING DIODE CARRIER - A light emitting diode (LED) carrier assembly includes an LED die mounted on a silicon submount, a middle layer that is thermally conductive and electrically isolating disposed below the silicon submount, and a printed circuit board (PCB) disposed below the middle layer. The middle layer is bonded with the silicon submount and the PCB. | 11-22-2012 |

20130155673 | LED LIGHTING APPARATUS WITH FLEXIBLE LIGHT MODULES - The present disclosure involves a street light. The street light includes a base, a lamp post coupled to the base, and a lamp head coupled to the lamp post. The lamp head includes a housing and a plurality of LED light modules disposed within the housing. The LED light modules are separate and independent from each other. Each LED light module includes an array of LED that serve as light sources for the lamp. Each LED light module also includes a heat sink that is thermally coupled to the LED. The heat sink is operable to dissipate heat generated by the LED during operation. Each LED light module also includes a thermally conductive cover having a plurality of openings. Each LED is aligned with and disposed within a respective one of the openings. | 06-20-2013 |
20130242550 | CHANGING LED LIGHT OUTPUT DISTRIBUTION THROUGH COATING CONFIGURATION - The present disclosure provides a lighting instrument. The lighting instrument includes a recessed light fixture, for example a troffer light or a batten light. The light fixture includes a plurality of light-emitting diode (LED) devices located on a board. The light fixture also includes a diffuser cap located on the board and housing the LED devices therein. The diffuser cap includes a plurality of coating regions. Each coating region is coated by a film containing white particles. The white particles can reflect and diffuse light emitted by the LED devices. The film in each coating region has a different white particle concentration level than other coating regions. | 09-19-2013 |
