| 20080310156 | Led illuminating device - A LED illuminating device includes an illuminating unit and a shell having a top side and chamber. The illuminating unit includes a PCB supported by the shell and one or more LED modules electrically and spacedly mounted on the PCB disposed in the chamber. Each of the LED modules includes a red LED, a blue LED and a green LED which are symmetrically arranged in a triangular manner side by side. The wires are emerged from two ends of the shell in a horizontal plane parallel to an adhesive layer so as to adapt for electrically linking two neighboring LED modules with each other in a flat plane manner. Finally, it reduces unnecessary length of the wire and minimizes the size of the device by decreasing the overall volume. | 12-18-2008 |
| 20090027901 | Outer case of LED module - An outer case of a LED module includes a top case and a bottom case to receive the LED module therebetween. The top case has a plurality of through holes and a plurality of blocks spacedly protruding from an inner side of the top case. The bottom case has a plurality of corresponding clip holes spacedly formed thereat, wherein the blocks are detachably engaged with the clip holes respectively to detachably couple the top case with the bottom case so as to form a cavity therebetween for receiving the LED module at a position that portions of LEDs are protruded through the through holes respectively. Two wire holes are formed at two sides of the top case when the top case is coupled with the bottom case for guiding wires of the LED module extending out of the cavity through the wire holes respectively. | 01-29-2009 |
| 20100072491 | LED chip module - A LED chip module comprises a base board comprising a PCB circuit therein; and a LED chip mounting on the base board comprising a supporting frame comprising a case having a peripheral wall defining an inner room therein, and a plurality of pairs of pins provided at both sides of the case, wherein each pair of pins extending through the peripheral wall of both sides of the case respectively from the inner room of the case to the outside of the case connecting with the PCB circuit; and a LED circuit is disposed in the case, which comprises a plurality of LEDs and a plurality of pairs of conducting wires, wherein each pair of conducting wire have one end connecting to the both sides of a LED respectively, and has another end connecting to a pair of pins in the inner room of the case respectively. | 03-25-2010 |

| 20080290257 | Automatic Gain Control in Photodetectors - The amount of gain applied to a photodetector such as a photomultiplier tube (PMT) is limited to an amount that does not cause the applied PMT bias voltage to overdrive, hence damage, the PMT. Techniques for limiting the PMT gain are implemented in a way that does not interfere with the precision with which the PMT gain may be established (by selection of a reference level) below that limited level. | 11-27-2008 |
| 20090279089 | Detection System for Birefringence Measurement - A method of controlling a light beam in an optical system includes a light source that directs a collimated light beam along a path, through a sample, and toward the active area of a stationary detector. The method includes the step selectively moving a lens into the path of the light beam for spreading the beam in instances where the path of the beam is altered by the sample between the source and the stationary detector The detector, therefore, is held stationary. Adjustment means are provided for increasing the intensity characteristic of the light that reaches the detector to account for a decrease in intensity that occurs when the lens is in the path of the light beam to spread the beam. | 11-12-2009 |
| 20090323064 | Measurement of Linear and Circular Diattentuation in Optical Elements - A system for measuring linear or circular diattenuation in an optical element includes a sample rotation stage for securing an optical element sample; a light source module for generating a source light beam and a detector module. The light source module and detector module are arranged with the sample rotation stage between them, thereby permitting the source light beam to propagate through a sample that may be secured in the sample stage and to the detector module. Linear motion control of the light source module and the detector module, as well as tilt control of the light source module, the sample rotation stage and the detector module is provided, thereby to facilitate detection, by the detector module of the modulated light intensity information corresponding to a diattenuation characteristic of the optical sample secured in the sample stage. | 12-31-2009 |
