摘要： A vehicle lamp having a light assembly and reflector assembly is provided. The light assembly has a light emitting diode (LED) mounted on a substrate to emit first and second solid angles. A reflective recycling surface is mounted on the substrate adjacent to the LED. The reflector assembly has a first reflector having a macro-focal reflective surface extending at the first solid angle relative to the LED and defines an output light pattern along an output optical axis. A second reflector has an ellipsoid reflective surface extending at the second solid angle relative to the LED and has a first focal point oriented at the LED and a second focal point oriented at the recycling surface. The second reflector reflects light emitted from the LED in the second solid angle back to the recycling surface. The recycling surface reflects light from the second reflector to be incident the first reflector.

摘要： A lens is provided with a light-incident face and a light-emitting face opposite the light-incident face. The lens body has a central optical axis extending in a forward direction through the light-incident face and the light-emitting face. The light-incident-face has a primary collector surface defined by a collimator profile revolved about a transverse axis perpendicular to the central optical axis. A pair of secondary collecting surfaces extend between the light-incident face and the light-emitting face, the secondary collecting surfaces oriented to reflect light internal to the lens body in the forward direction through total internal reflection. The light-emitting face is defined by a central primary collimating output surface protruding from upper and lower secondary output surfaces

摘要： A lighting system and method are provided for controlling a PWM duty cycle. The lighting system is provided with at least one device that is configured to emit light in response to receiving electrical power. The lighting system includes a power circuit and a feedback circuit. The power circuit is configured to selectively supply power to the device at a duty cycle corresponding to a first mode and a second mode, wherein the duty cycle of the first mode is less than 10% of the duty cycle of the second mode. The feedback circuit is configured to provide a feedback signal that is indicative of the energy provided to the device. The power circuit is further configured to disable power to the device during the first mode in response to the energy being greater than a threshold energy value, thereby adjusting the duty cycle.

摘要： An under-cabinet lighting fixture includes at least one bulb of less than about 35 watts contained within a housing that is devoid of any dedicated heat dissipation back vents on the back or top of the lighting unit. The lighting fixture has a reflective coating applied to the interior of the housing unit itself, which acts as a mirrored surface to reflect the bulb's illumination. A glass lens is supported by a metal frame that runs around the periphery of such lens and the lens cover itself is connected to the housing by pivoting hinges and is held in place when closed by one or more securing elements.

摘要： A headlamp for a vehicle includes a holder for a light-distribution optical fiber of the type that has an output end emanating light of known spatial-intensity distribution, an optical coupler that has an input end adjacent the holder and includes a plurality of elements, each of which is positioned to receive light from a selected area of the light of known spatial intensity distribution and to alter the intensity or spatial distribution of that light to provide a predetermined spatial intensity distribution at an output of said coupler, and a projection lens to project the predetermined spatial intensity distribution to a desired illumination pattern. The optical coupler may be in the form of a mask and one or more filters or may be a number of light-transmitting elements that carry light from one spatial part of the input to a different spatial part in the output. In general, the optical coupler alters the intensity or angular distribution of the light pattern at the input to produce a desired light pattern at the output for projection onto the road by the projection lens.

摘要： A light guide is provided having an elongate body extending in a longitudinal direction having a light transmission portion with a forward light exit surface and a reflective track extending opposite the light exit surface. A plurality of reflective elements are formed along the reflective track and spaced apart in the longitudinal direction. Each reflective element has a center segment and a pair of edge segments each oriented at a spread angle from the center segment toward the light transmission portion, thereby increasing a spread of light output in a horizontal direction from the light transmission portion.
