  • Patent number: 6828170
    Abstract: A semiconductor optical radiation package includes a leadframe, at least one semiconductor optical radiation emitter, and an encapsulant. The leadframe has a heat extraction member, which supports the semiconductor optical emitter and provides one or more thermal paths for removing heat generated within the emitter to the ambient environment, as well as at least two electrical leads for providing electrical coupling to the semiconductor optical radiation emitter. The encapsulant covers and protects the emitter and optional wire bonds from damage and allows radiation to be emitted from the emitter into the ambient environment. The semiconductor optical radiation package provides high emitted flux and is preferably compatible with automated processing techniques.

  • Patent number: 6737629
    Abstract: Light sensors having a wide dynamic range are used in a variety of applications. A wide dynamic range light sensor includes an exposed photodiode light transducer accumulating charge in proportion to light incident over an integration period. Sensor logic determines a light integration period prior to the beginning of integration and the charge is reset. Charge accumulated by the exposed light transducer over the light integration period is measured and a pulse having a width based on the accumulated charge is determined.

  • Patent number: 6672745
    Abstract: A vehicle system is disclosed that includes a vehicle lamp assembly including a plurality of LEDs that emit white light so as to function as an illuminator light. The lamp assembly also may include a plurality of LEDs that emit colored light, such as red or red-orange, so as to function as a signal light. Alternatively or additionally, the lamp assembly may include a camera of a vehicle imaging system. The lamp assembly may serve as a center high mounted stop light or as a tail light. The system also includes a controller that rapidly pulses the LEDs on and off at a rate that is imperceivable by the human eye. The pulsing intervals of the LEDs may be related to the readout intervals of the camera sensor array. In this manner, the LEDs may be pulsed on during camera readout so as to increase their intensity while the camera is capturing an image, or may be pulsed off during camera readout to prevent feedback glare from interfering with image capture by a highly sensitive image sensor array of the camera.

  • Patent number: 6650457
    Abstract: A mirror assembly includes a housing, an angularly adjustable power pack, wires for supplying power and mirror angle control, an electrochromic mirror subassembly including a heater, and a turn signal device. The components include individual connectors that plug into a multi-prong connector on the bundle of wires, or that piggyback into each other. Optionally, the heater incorporates an internal wire with end connectors for communicating power to opposite sides of the heater, and also includes layers of light-transmitting/diffusing material for diffusing light passing from the turn signal device through the diffusing material. A printed circuit board fits into a pocket in the panel-shaped carrier, and an integral retainer releasably secures the printed circuit board. The power pack is attached to the carrier via a ring of resilient fingers, and a continuous hoop flange prevents distortion of the carrier and in turn of the glass elements in the mirror subassembly.

  • Patent number: 6616312
    Abstract: A lighting apparatus for a vehicle includes a light source attached inside the vehicle, such as to an “A” pillar adjacent a front of a side window of the vehicle, where the light source is oriented to direct light toward a ground area adjacent the vehicle for security and convenience. Variations include also reflecting a portion of the light from the light source off an outside rearview mirror onto the ground area, and also directing a portion of the light toward an area inside the vehicle.

  • Patent number: 6523976
    Abstract: An illuminator assembly, having a plurality of LEDs on a vehicular support member in a manner such that, when all of the LEDs are energized, illumination exhibiting a first perceived hue, e.g., blue-green, and projected from at least one of the LEDs overlaps and mixes with illumination exhibiting a second perceived hue, e.g., amber, which is distinct from said first perceived hue and which is projected from at least one of the remaining LEDs in such a manner that this overlapped and mixed illumination forms a metameric white color and has sufficient intensity and color rendering qualities to be an effective illuminator.

  • Patent number: 6471362
    Abstract: An electrified rearview mirror includes a housing supporting a rearview mirror subassembly, and a bezel attached to the housing. The bezel includes a section of material defining a plurality of three-sided button openings on a face of the bezel, with the openings extending onto a bottom wall of the housing. A push-button is pivotally supported in each opening, with the hinge axis of the push-buttons being at a low position on the respective buttons so that the buttons are not accidentally depressed when the mirror housing is grasped by a vehicle driver to adjust an angle of the mirror. The bezel and buttons include pairs of tabs and mating slots that form a quick-attach bottom pivot, and further include stops and hooks at their top that form stroke-limiting mechanisms for controlling button movement. The buttons can be operably snapped into position on the bezel with minimal assembly time.
