Abstract: There is herein described a patterned thin-film wavelength converter (100,200) which comprises a substrate (104) having a first patterned surface with a first pattern, and a thin film (106,206) deposited on the first patterned surface. The thin film consists of a wavelength converting material and has a second patterned surface that is distal from the substrate. The second patterned surface has a second pattern that is substantially the same as the first pattern of the substrate. An advantage of the patterned thin-film wavelength converter is that post-deposition processing is not required to produce a textured surface on the wavelength converting material. A method of making the patterned thin-film wavelength converter is also described.

Abstract: A laser-activated remote phosphor (LARP) target comprising a substrate 8114), a dichroic filter(120) disposed on the substrate, a phosphor converter (102) disposed on the dichroic filter, and an aperture structure (230) disposed on the phosphor converter. The phosphor converter comprises a luminescent material that at least partially converts a primary laser pump light (110) into a secondary light (108) having a different peak wavelength. The dichroic filter substantially transmits the primary laser pump light and substantially reflects the secondary light. The aperture structure covers the lighting emitting surface except for an aperture (240) in the aperture structure whereby a substantial portion of secondary light passes through the aperture in the aperture structure for coupling into an optical system.

Abstract: There is herein described a light source that homogenizes the light produced by a large area array of forward directed LEDs (102) mounted on highly reflective substrate (106), while achieving a low-profile form factor and maintaining high efficacy. The LED light source employs a diffuser (120) comprised of two diffusing layers: a low scattering diffusing layer (118) bonded to the LEDs (102) and a high scattering diffusing layer (114) that is bonded to the low scattering diffusing layer (118). The LED light source achieves good diffuse illumination with a thin diffuser by making use of a light channeling effect between the highly reflective substrate (106) and the high backscattering from the high scattering diffusing layer (114).

Abstract: A wavelength-conversion plate is described herein. The wavelength conversion plate may include a converter of a first ceramic material and a reflector of a second ceramic material. The first ceramic material converts the primary light emitted by a light source such as a light emitting diode (LED) into a secondary light and the second ceramic material reflects the secondary light emitted by said converter. Preferably, the converter is inlaid into the reflector so that the reflector surrounds an outer edge of the converter. Such a configuration has an advantage of reducing unwanted side emissions from the converter.

Abstract: There is herein described a light source comprising a semiconductor device emitting a primary light, a thermally conductive optic having a reflective coating and a wavelength converter having a front surface and a rear surface. The optic is mounted to the rear surface of the wavelength converter and the primary light impinges on the wavelength converter in an emission region. The wavelength converter converts at least a portion of the primary light into a secondary light that is emitted from the front and rear surfaces of the converter and the optic reflects secondary light emitted from the rear surface back into the emission region. The light source may be used in either transmissive or reflective configurations.

Abstract: There is herein described a method for forming a ceramic wavelength converter assembly which achieves a direct bonding of an alumina-based ceramic wavelength converter to an alumina-based ceramic substrate such as polycrystalline or sapphire. The method comprises applying a silica-containing layer between the converter and the substrate and then applying heat to bond the converter to the substrate to form the ceramic wavelength converter assembly. Because direct bonding is achieved, the ceramic wavelength converter may operate at much higher incident light powers than conventional silicone glue-bonded converters.

Abstract: The present disclosure is directed to orientation-independent device configuration and assembly. An electronic device may comprise conductive pads arranged concentrically on a surface of the device. The conductive pads on the device may mate with conductive pads in a device location in circuitry. Example conductive pads may include at least a first circular conductive pad and a second ring-shaped conductive pad arranged to concentrically surround the first conductive pad. The concentric arrangement of the conductive pads allows for orientation-independent placement of the device in the circuitry. In particular, the conductive pads of the device will mate correctly with the conductive pads of the circuitry regardless of variability in device orientation. In one embodiment, the device may also be configured for use with fluidic self-assembly (FSA). For example, a device housing may be manufactured with pockets that cause the device to attain neutral buoyancy during manufacture.

Abstract: The present disclosure is directed to light converter assemblies with enhanced heat dissipation. A light converter assembly may comprise a confinement material applied to at least a first substrate and a phosphor material also deposited on the first substrate so as to be surrounded by the confinement material. The first substrate may be hermetically sealed to a second substrate using the confinement material so that the phosphor material is confined between the substrates and protected from atmospheric contamination. The substrates may comprise, for example, sapphire to allow for light beam transmission and heat conductance. Confinement materials that may be employed to seal the first substrate to the second substrate may include, for example, silicon or a metal (e.g., silver, copper, aluminum, etc.) The phosphor material may comprise, for example, at least one quantum dot material.
