Abstract: An LED light source (10) comprises a ceramic substrate (20) with first and second opposed surfaces (30, 40). Pockets (50) are formed in the first surface (30) and each of the pockets includes a bottom (60) and a sidewall or sidewalls (70). A final electrical contact (105) comprised of a first electrically conductive material (57) with a coating of a second electrically conductive material (100) thereover is positioned in each of the pockets (50). An LED (110) is positioned in each of the pockets (50) and affixed to the electrical contact (105) and electrical connections (120), preferably in form of wire bonds, join the LEDs, the electrical connections (120) extending from a first LED (110) to an adjacent electrical contact (105). The ceramic substrate (20) is formed by injection molding a ceramic material and binder to form a green substrate (12) and subsequently sintering the green substrate to form the substrate (20).

Abstract: A lighting module has a base, a top, a longitudinal axis from the base's center to the top's center, and a lateral edge surrounding the axis. Solid state light sources at the base emit excitation light, having an excitation wavelength and an angular distribution centered about the axis, toward the top. A lens defines a lateral edge of the module, which extends from the base to the top and reflects the excitation light. A phosphor surface of the module, shaped as a funnel having a wide end proximate the top and a narrow end proximate the base, receives and absorbs the excitation light, producing phosphor light that exits the module through the lateral edge. The phosphor light's wavelength is greater than the excitation wavelength, and has an angular distribution at each point on the phosphor surface centered about a local surface normal with respect to the phosphor surface.

Abstract: A light emitting diode (LED) light engine includes a solid transparent dome mounted on one or more LED dies to form a base module, a flexible sheath having embedded therein a phosphor that converts light of a first wavelength range to light of a second wavelength range, the sheath being attached to the base module so that the sheath conforms to a light emitting surface of the dome. The sheath emits light of the second wavelength range when the LED is emitting light of the first wavelength range. Further sheaths may be formed each with different phosphors or phosphor blends, and one of the sheaths may be selected to cover the base module depending on the color of light to be produced by the light engine.

Abstract: A light engine kernel for a light emitting diode (LED) includes a solid body of transparent material having an index of refraction of at least 1.5. The body has a domed, light-emitting top that is an inverted parabola of revolution, a reflective sidewall that is a compound parabolic concentrator (CPC), and a cavity at a focus of the CPC that is adapted to receive an LED. The domed top may include a phosphor coating of a yellow-emitting phosphor. The cavity may be adapted to receive only a single LED or plural LEDs of the same or different colors on a board. The kernel and LED are not integrally formed, reducing thermal degradation of the phosphor coating and improving application flexibility.

Abstract: A lamp includes a linearly extending heat sink, blue-light-emitting LEDs mounted on the heat sink, and a light emitting cover mounted on the heat sink in line with the LEDs, a first portion of the cover opposite the LEDs including a phosphor that is excited by the LEDs to emit white light. The cover may be a tube with the LEDs outside the tube, a portion of the tube nearest the LEDs being transparent and receiving light from the LEDs. The tube may include reflectors that are attached to an exterior surface of the tube to hold the tube on the heat sink. Alternatively, the cover may enclose the LEDs on the heat sink, where a portion of the cover has an interior surface that reflects light from the LEDs to the first portion. The lamp may include electrical connections that allow for multiple lamps to be connected in series.

Abstract: The seal temperature of a reflector lamp having a ceramic metal halide light source is reduced by a light absorbing layer which is provided in a region of the outer jacket adjacent to the electrode seal. Light reflected within the neck cavity of the reflector lamp impinges on the light absorbing layer and is absorbed before it can reach the electrode seal which is at least partially located in the neck of the reflector. The heat from the absorbed light is conducted into the base of the lamp to be dissipated in the socket.

Abstract: A ceramic discharge lamp, and method of operating same, is provided which contains a cavity between a clear sapphire tube and a PCA cap. During lamp operation, the cavity holds the molten salts to act as a constant temperature reservoir of the molten salts. By manipulating the shape of the cap, for example the curvature of the internal dome, or by building in an offsetting lip, the volume of the cavity can be controlled. By adjusting the thickness of the adjacent cap walls, or by the addition of exterior heat sinking or radiating features on the cap, the temperature of the salt reservoir can be further controlled. The reservoir facilitates providing materials for the plasma at a constant pressure, but without letting the fill condensate flow over and coat the light emitting portions of the clear sapphire transmission cavity wall.
