Abstract: A light emitting device is produced using a plurality of light emitting diodes within a light mixing cavity formed by surrounding sidewalls. The sidewalls may be integrally formed as part of a surrounding heat sink or alternatively may be an insert into a cavity within a heat sink. The reflective sidewalls may be coated with a diffusing material and/or covered with one or more phosphors. Multiple phosphors are located at different locations of the cavity, e.g., on the sidewalls, a window covering the output port, or on a reflector attached to the bottom of the cavity. The light emitting diodes may be positioned rotationally symmetrically around the optical axis on a board.

Abstract: A light emitting device is produced using one or more light emitting diodes within a light mixing cavity formed by surrounding sidewalls. The light emitting device includes a light adjustment member that is movable to alter the shape or color of the light produced by the light emitting device. For example, the light adjustment member may alter the exposure of the wavelength converting area to the light emitted that is emitted by the light emitting diode in the light mixing cavity. Alternatively, the height of a lens may be adjusted to change the width of the beam produced. Alternatively, a movable substrate with areas of different wavelength converting materials may adjustably cover the output port of the light mixing cavity to alter the color point of the light produced.

Abstract: An LED module includes an upper housing with in internal cavity and a lower housing. At least one light emitting diode is held in the LED module and emits light into the internal cavity, which is emitted through an output port in the upper housing. An optical structure, which may be disk or cylinder shaped may be mounted over the output port and light is emitted through the top surface and/or edge surface of the optical structure. The lower housing has a cylindrical external surface, which may be part of a fastener, such as screw threads, so that the LED module can be coupled to a heat sink, bracket or frame. The light emitting diode is thermally coupled to the lower housing, which may serve as a heat spreader. Additionally, a flange may be disposed between the upper housing and lower housing.

Abstract: A solid state illumination device includes a semiconductor light emitter mounted on a base and surrounded by sidewalls, e.g., in a circular, elliptical, triangular, rectangular or other appropriate arrangement, to define a chamber. A top element, which may be reflective, may be coupled to the sidewalls to further define the chamber. The light produced by the semiconductor light emitter is emitted through the sidewalls of the chamber. The sidewalls and/or top element may include wavelength converting material, for example, as a plurality of dots on the surfaces. An adjustable wavelength converting element may be used within the chamber, with the adjustable wavelength converting element being configured to adjust the surface area that is exposed to the light emitted by the semiconductor light emitter in the chamber to alter an optical property of the chamber.

Abstract: Low profile, side-emitting LEDs are described that generate white light, where all light is emitted within a relatively narrow angle generally parallel to the surface of the light-generating active layer. The LEDs enable the creation of very thin backlights for backlighting an LCD. In one embodiment, the LED emits blue light and is a flip chip with the n and p electrodes on the same side of the LED. Separately from the LED, a transparent wafer has deposited on it a red and green phosphor layer. The phosphor color temperature emission is tested, and the color temperatures vs. positions along the wafer are mapped. A reflector is formed over the transparent wafer. The transparent wafer is singulated, and the phosphor/window dice are matched with the blue LEDs to achieve a target white light color temperature. The phosphor/window is then affixed to the LED.

Abstract: An injection device 100 comprises a housing 102 which is adapted to receive a fluid container 120. The housing 102 is also adapted to hold the fluid container 120 stationary relative to the housing 102 during use of the device 100. The injection device 100 also comprises a discharge nozzle 128 which is movable between a first retracted position in which the discharge nozzle 128 is contained within the housing 102 and a first extended position in which the discharge nozzle 128 has moved relative to the fluid container 120 and extends from the housing 102 through an exit aperture 138 of the housing 102. The fluid container 120 and discharge nozzle 128 are in fluid communication with each other in the first extended position. Extension of the discharge nozzle and expulsion of a predetermined and fixed quantity of fluid can be achieved in a single continuous action.

Abstract: Various embodiments of corner-coupled backlights are described, where one or more white light LEDs are optically coupled to a truncated corner edge of a solid rectangular light guide backlight. The one or more LEDs are mounted in a small reflective cavity, whose output opening is coupled to the truncated corner of the light guide. The reflective cavity provides a more uniform light distribution at a wide variety of angles to the face of the truncated corner to better distribute light throughout the entire light guide volume. To enable a thinner light guide, the LED die is positioned in the reflective cavity so that the major light emitting surface of the LED is parallel to the top surface of the light guide. The reflective cavity reflects the upward LED light toward the edge of the light guide.
