    Abstract: An apparatus and method is characterized by providing an optical transfer function between a predetermined illuminated surface pattern, such as a street light pattern, and a predetermined energy distribution pattern of a light source, such as that from an LED. A lens is formed having a shape defined by the optical transfer function. The optical transfer function is derived by generating an energy distribution pattern using the predetermined energy distribution pattern of the light source. Then the projection of the energy distribution pattern onto the illuminated surface is generated. The projection is then compared to the predetermined illuminated surface pattern to determine if it acceptably matches. The process continues reiteratively until an acceptable match is achieved.

  • Patent number: 9099568
    Abstract: A layer of microscopic, 3-terminal transistors is printed over a first conductor layer so that bottom electrodes of the transistors electrically contact the first conductor layer. A first dielectric layer overlies the first conductor layer, and a second conductor layer over the first dielectric layer contacts intermediate electrodes on the transistors between the bottom electrodes and top electrodes. A second dielectric layer overlies the second conductor layer, and a third conductor layer over the second dielectric layer contacts the top electrodes. The devices are thus electrically connected in parallel by a combination of the first conductor layer, the second conductor layer, and the third conductor layer. Separate groups of the devices may be interconnected to form more complex circuits. The resulting circuit may be a very thin flex-circuit.

  • Patent number: 9081175
    Abstract: The present invention relates to a fluorescence observation device, a domed base and a fluorescence microscope. The fluorescence observation device includes a dome, a multi-angle light-emitting unit and a controller unit. The dome includes a transparent thermal insulation layer and a heat sink layer. The multi-angle light-emitting unit includes multiple directional narrow light field electro-luminescence devices thermally connected to the heat sink layer and adapted to emit light at different angles to pass through the transparent thermal insulation layer. The narrow light field electro-luminescence devices are selectively activated to emit light by the controller unit, so that the illumination angle of the multi-angle light-emitting unit can be adjusted. The fluorescence observation device can be combined with a base to constitute the domed base. Alternatively, narrow light field electro-luminescence devices are mounted on the base.

  • Patent number: 9029898
    Abstract: The present invention relates to a light emitting diode (LED). The LED comprises an LED die, one or more metal pads, and a fluorescent layer. The characteristics of the present invention include that the metals pads are left exposed for the convenience of subsequent wiring and packaging processes. In addition, the LED provided by the present invention is a single light-mixing chip, which can be packaged directly without the need of coating fluorescent powders on the packaging glue. Because the fluorescent layer and the packaging glue are not processed simultaneously and are of different materials, the stress problem in the packaged LED can be reduced effectively.
