摘要： A polarized light emitting diode (LED) includes a marker indicating a polarization direction. A package for the LED also includes a marker indicating the polarization direction. The markers on the LED and package are used for mutual alignment, wherein the LED is attached in a favorable orientation with respect to a package, so that the polarization direction of emitted light from the package is apparent. The marker is placed on the LED before die separation and the marker is placed on the package before alignment. The marker on the LED comprises a photolithographic pattern, an asymmetric die shape, a notch on the die, or a scratch on the die, while the marker on the package comprises an electrode shape or pattern, an asymmetric package shape, a notch on the package, or a scratch on the package. Finally, the LED or package may be installed in an external circuit or system that also indicates the polarization direction.

摘要： A device for displaying images positions a luminescent material between a light source and a liquid crystal display (LCD). The light source, which comprises one or more nonpolar or semipolar III-nitride based light emitting diodes (LEDs), emits a primary light having a specified polarization direction and comprising one or more first wavelengths. This primary light emitted by the light source is a linearly polarized light that eliminates any need for a polarizer. The luminescent material, which comprises one or more phosphors, is optically pumped by the primary light and emits a secondary light having the polarization direction of the primary light, wherein the secondary light is comprised one or more second wavelengths that are different from the first wavelength. This secondary light emitted by the luminescent material is a colored light that eliminates any need for a color filter. The LCD receives the secondary light and displays one or more images in response thereto.

摘要： An off-axis cut of a nonpolar III-nitride wafer towards a polar (−c) orientation results in higher polarization ratios for light emission than wafers without such off-axis cuts.

摘要： A lighting apparatus for emitting polarized white light, which includes at least a first light source for emitting primary light comprised of one or more first wavelengths and having a first polarization direction; and at least a second light source for emitting secondary light in the first polarization direction, comprised of one or more secondary wavelengths, wherein the first light and the secondary light are combined to produce a polarized white light. The lighting apparatus may further comprise a polarizer for controlling the primary light's intensity, wherein a rotation of the polarizer varies an alignment of its polarization axis with respect to the first polarization direction, which varies transmission of the primary light through the polarizer, which controls a color co-ordinate or hue of the white light.
