Abstract: Light-emitting devices and/or systems are described. In some embodiments, light-emitting devices and/or systems can recycle at least some light generated by a light-generating region of the light-emitting device. In one embodiment, a light-emitting assembly comprises an illumination component having at least one light input surface and at least one light emission surface, a solid-state light source configured to emit at least some light into the at least one light input surface of the illumination component, a polarization manipulation region configured to alter a polarization of light in a different way for light impinging on different locations of the polarization manipulation region, and a polarizer configured to receive at least some light emitted via the at least one light emission surface of the illumination component and further configured to output light having a first polarization and return, to the polarization manipulation region, light having a second polarization.

Abstract: Light-emitting devices and/or systems are described. In some embodiments, light-emitting devices and/or systems can recycle at least some light generated by a light-generating region of the light-emitting device. In one embodiment, a light-emitting device comprises a semiconductor light-emitting material stack including a light-generating region and a light emission surface, wherein the light-emitting material stack has a first refractive index at the light emission surface. The light-emitting device further comprises a polarizer and a material region having a second refractive index and at least partially disposed between the light emission surface of the light-emitting material stack and the polarizer, wherein the second refractive index is less than 0.7 times the first refractive index. In one embodiment, a polarizer is disposed over a light emission surface of a light-emitting material stack within a minimum distance of greater than zero and less than 2.5 microns.

Abstract: Thermal management of display systems including LCD systems is provided. The LCD systems may utilize LEDs as a light source. The LEDs may be supported on a heat pipe. The heat pipe facilitates conduction and dissipation of heat generated by the LEDs which may otherwise damage components of the display system.
