Abstract: An integrated LED light system (100) including a printed circuit board (110, 410) and a submount (120, 420) mounted on the printed circuit board (110, 410). System (100) further includes an array of LEDs (125, 425) in electrical communication with the submount (120, 420) to receive forward currents. The array of LEDs (125, 425) includes one or more LEDs for emitting one or more color of lights in response to a reception of the forward currents from the submount (120, 420). System (100) additionally includes a heatsink (130, 430) supporting the printed circuit board (110, 410) to conduct and dissipate heat away from the printed circuit board (110, 410), the submount (120, 420), and the LED(s) (125, 425). System (100) further includes a reflector cup (140, 440) mounted on the printed circuit board (110, 410) and in optical communication with the LED(s) (125, 425) to focus the at least one color of light.

Abstract: An optical system (100, 200) and method of use includes at least one light source (105, 106, 107, 211, 302), each of which transmit light substantially of a particular wavelength range in a substantially randomly polarized state or an unpolarized state. The optical system (100, 200) includes a reflective polarizer (108, 204, 305) coupled to the light source, and an element (101, 102, 103, 201, 202, 203, 301) that redirects the reflected light through the light source and onto the reflective polarizer. Illustratively there is substantially no optical distance between the light source (105, 106, 107, 211, 302) and the element (101, 102, 103, 201, 202, 203, 301). An optical package, which recycles reflected light is also disclosed.

Abstract: The invention provides an apparatus that illuminates a rod (130) comprising a plurality of light emitting diode chips (110), the light emitting diode chips (110) forming at least one multi-chip package; at least one reflector (120), the reflector optically connected to the multi-chip package (110); and an output rod (130), the output rod optically connected to the reflector (120).

Abstract: According to this invention, a side-emitting illumination device for uniformly distributing light is composed of an LED light source, a light-transmitting rod which permits total internal reflection, and outcoupling material affixed to an outer surface of the rod. Light enters the rod at one end and travels along the rod by total internal reflection. Light that hits the outcoupling material is angularly distributed based on the width of the outcoupling material.

Abstract: A light source includes an array of LED components in each of a plurality of colors such as red, green, and blue in the entrance aperture of a tubular reflector which has an exit aperture, an optic axis extending between the apertures, and a reflective circumferential wall extending between the apertures to reflect and mix light from the array of LED components. At least a portion of the circumferential wall of the reflector body has a polygonal cross-section taken normal to the optic axis, and at least a portion of the cross-section taken parallel to the optic axis includes segments of a curve joined one to the next to form a plurality of facets for reflecting light from the LED components to said exit aperture. Preferably, the segments of the curve included in the cross-section of the reflector body taken parallel to the optic axis are contiguous, linear trapezoidal facets.
