20100270908 | FLUORESCENT LAMP COMPATIBLE LED ILLUMINATING DEVICE - A fluorescent lamp compatible LED illuminating device ( | 10-28-2010 |
20100181591 | LED ILLUMINATION DEVICE USING DIFFRACTION MEMBER - An object of this invention is to provide an LED illumination device that can substitute for a fluorescent light and obtain uniform light with high efficiency. The LED illumination device comprises an LED with a thin-plate-shaped semiconductor element body transmitting the light generated in a PN junction area in a thickness direction and emits it from the surface, a surface electrode that covers the surface of the semiconductor element body, and columnar dielectric antennas that penetrate the surface electrode in the thickness direction and that condense the light transmitted in a body of the semiconductor element and emit it outside, a diffraction member that is arranged on a luminous surface side of the LED and that diffracts and disperses the light emitted by the LED, and a diffusion member that is arranged outside the diffraction member and that diffuses the light dispersed by the diffraction member and emits it outside. | 07-22-2010 |
20100176411 | FLUORESCENT-LAMP-TYPE LED LIGHTING DEVICE - To provide a fluorescent-lamp-type LED lighting device that has a large amount of light intensity and that can replace a highly efficient existing lighting device, the fluorescent-lamp-type LED lighting device comprises an LED ( | 07-15-2010 |
