摘要: A lighting apparatus having wavelength-converting materials formed in a carrier layer is disclosed. In one embodiment, the lighting apparatus has a light source attached to a substrate that is assembled in a housing. The light source is configured to emit a substantially narrow band light that is transformed into broad-spectrum white light by the wavelength-converting materials positioned on the carrier layer. The wavelength-converting materials and the carrier layer are distanced away from the light source, such that the carrier layer is thermally isolated from the light source.

摘要: An eye detection system for safe detection of the eye positions of a subject estimates the distance from the eye detection system to the subject and reduces the power level of at least one primary light source of the eye detection system if the subject is too close to the eye detection system. If the subject is not too close to the eye detection system, the power level of the at least one primary light source of the eye detection system is increased, provided the power level is below a predetermined maximum power level. Primary light from the at least one primary light source reflected from the subject is sensed by an imager to obtain one or more images, from which the eye positions of the subject are estimated.

摘要: A lighting device having a light source, light pipe, and a light-dispensing element is disclosed. The light source emits light at a first wavelength and transmits that light to the light pipe. The light dispensing emitter includes an extended section coupled to the light pipe that emits light along the extended section, the extended section having a side surface through which light exits from the extended section. The extended section can include a medium that is transparent to light of the first wavelength and a plurality of scattering centers, the extended section having a shape such that light that is not scattered by the scattering centers is trapped within the extended section by internal reflection. The extended section can also include a light conversion material that converts light of the first wavelength to light of a second wavelength.

摘要: A light source having a plurality of dies mounted on leads that are partially enclosed in a plastic body is disclosed. Each die is powered by first and second contacts. One contact is connected to the lead on which the die is mounted. Light from the LED exits the die through the top surface. Each lead includes a layer of metal of substantially constant thickness. The layer includes a boundary, a die mounting region within the boundary and a heat transfer region within the boundary. The boundary increases in a dimension perpendicular to a line connecting the die mounting region and the heat transfer region. The leads are arranged such that the die mounting regions are proximate to a first point and oriented such that the lines radiate from the first point. The light source can be manufactured using conventional lead frame techniques.

摘要: A packaged circuit and method for packaging an integrated circuit are disclosed. The packaged circuit has a lead frame, an integrated circuit chip, and an encapsulating layer. The lead frame has first and second sections, the first section including a lateral portion, a chip mounting area and a first extension. The integrated circuit chip is mounted in the chip mounting area and is in thermal contact with the chip mounting area. The encapsulating layer has top, bottom, and first and second side surfaces. The first extension is bent to provide a first heat path from the chip mounting area to the bottom surface. The heat path connects the heat chip mounting area to the bottom surface without passing through the first and second side surfaces and provides a heat path that has less thermal resistance than the heat path through either the lateral portion or the second section.
