| 20090272989 | LIGHT EMITTING DEVICE HAVING STACKED MULTIPLE LEDS - A light emitting device and method of producing the same is disclosed. The light emitting device includes a heterostructure having a plurality of light emitting diodes (LEDs) stacked one on top of another. | 11-05-2009 |
| 20090272997 | LED STRUCTURE TO INCREASE BRIGHTNESS - A light emitting semiconductor device comprising an LED having an emission aperture located on a surface of the LED and the emission aperture has a size that is smaller than a surface area of the LED where the emission aperture is formed. The device further includes a reflector surrounding both side walls, a bottom surface, and portions of a surface of the LED where the emission aperture is formed or surrounding the bottom surface and portions of the surface of the LED where the emission aperture is formed so that an area on the surface uncovered by the reflector is the emission aperture and is smaller than the area of the LED. Alternatively, in the light emitting semiconductor, the surface of the LED substantially aligned with the emission aperture may be roughened and the surface of the LED beyond the emission aperture may be smooth. The surface of the LED beyond the emission aperture may also be covered by a low loss reflector. | 11-05-2009 |
| 20090273001 | WIRE BONDING TO CONNECT ELECTRODES - A light emitting apparatus includes a semiconductor layer having an electrode with two traces physically separated from one another. The light emitting apparatus further includes a wire bond electrically connecting the two traces. | 11-05-2009 |
| 20100051983 | POLARIZATION RECYCLING OPTICS FOR LEDS - An integrated multi-layer apparatus and method of producing the same is disclosed. The structure comprises an LED configured to emit first and second polarized light, and a polarizing layer configured to pass a first polarized light and reflect the second polarized light back to the LED, wherein the LED is further configured to randomly scatter the second polarized light reflected from the polarizing layer and redirect the scattered light back to the polarizing layer. | 03-04-2010 |
| 20100053980 | OPTICAL PLATFORM TO ENABLE EFFICIENT LED EMISSION - An integrated multi-layer apparatus and method of producing the same is disclosed. The apparatus comprises an LED, a beam shaping layer, and a refracting layer between the beam shaping layer from the LED. The refracting layer may have an index of refraction lower than the index of refraction of the LED and the beam shaping layer. | 03-04-2010 |
| 20110073893 | LED STRUCTURE TO INCREASE BRIGHTNESS - A light emitting semiconductor device comprising an LED having an emission aperture located on a surface of the LED and the emission aperture has a size that is smaller than a surface area of the LED where the emission aperture is formed. The device further includes a reflector surrounding both side walls, a bottom surface, and portions of a surface of the LED where the emission aperture is formed or surrounding the bottom surface and portions of the surface of the LED where the emission aperture is formed so that an area on the surface uncovered by the reflector is the emission aperture and is smaller than the area of the LED. Alternatively, in the light emitting semiconductor, the surface of the LED substantially aligned with the emission aperture may be roughened and the surface of the LED beyond the emission aperture may be smooth. The surface of the LED beyond the emission aperture may also be covered by a low loss reflector. | 03-31-2011 |
| 20110103071 | OPTICAL PLATFORM TO ENABLE EFFICIENT LED EMISSION - An integrated multi-layer apparatus and method of producing the same is disclosed. The apparatus comprises an LED, a beam shaping layer, and a refracting layer between the beam shaping layer from the LED. The refracting layer may have an index of refraction lower than the index of refraction of the LED and the beam shaping layer. | 05-05-2011 |
