摘要： A light-emitting diode with an improved service life is provided. The diode is formed from a transparent outer shell that contains a heat-resistant encapsulant at least partially surrounding a light-emitting diode clip. The first encapsulant is compressed between the outer shell and a second encapsulant when it is sealed into the outer shell by the second encapsulant.

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 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.

摘要： A light source having first and second phosphor-converted component light sources is disclosed. The first component light source includes a first LED that emits light at a first wavelength and a first luminescent conversion material layer that converts light of the first wavelength to light of a first output wavelength, and the second component light source includes a second LED that emits light at a second wavelength and a second luminescent conversion material layer that converts light of the second wavelength to light of a second output wavelength that is different from the first output wavelength. The first and second LEDs are constructed in the same material system, preferably in the same batch of wafers on the fabrication line. A controller generates a current through each of the first and second LEDs that results in the light source generating light that is perceived to be a predetermined color.

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.
