  • Patent number: 10300841
    Abstract: In a vehicle lamp device, light emitted by a LED enters a concentration element of a lens and is irradiated from an irradiating face of the concentration element. The reflecting face of the concentration element surrounds a central axis of the concentration element. Light that enters the concentration element is reflected by the reflecting face toward a central axis side of the concentration element, and light reflected by the reflecting face is irradiated from the irradiating face. The concentration element is thus able to efficiently concentrate light emitted by the LED.

  • Patent number: 9033518
    Abstract: An illumination system includes a first light source, a first rotation wheel, a first phosphor element, and a light combining element. The first light source is capable of emitting a first color beam. The first rotation wheel is disposed on a transmission path of the first color beam and includes a first transmissive region and a first reflective region. The first transmissive region is capable of allowing the first color beam to pass through so as to form a first color transmissive beam. The first reflective region is capable of reflecting the first color beam to form a first color reflective beam. One of the first color transmissive and reflective beams excites the first phosphor element to form a second color beam. The light combining element combines the second color beam and a beam originating from the other one of the first color transmissive and reflective beams.

  • Publication number: 20150109782
    Abstract: An LED luminaire includes a thermal management system and features minimal glare while allowing for use of traditional luminaire housing. The luminaire of the depicted embodiments comprises a luminaire housing, an LED light module, an LED driver, a diffuser, and reflectors. The LED light module comprises at least one LED array, a primary thermal interface, and a secondary thermal interface. These thermal interfaces, particularly when used in conjunction with a conductive housing, allow for optimal thermal management by utilizing both natural convection and conduction to remove the heat from inside the luminaire into the surrounding air. Additionally, in certain embodiments, the position of the LED arrays within the housing in combination with the reflector design creates an optical path resulting in an indirect light source that minimizes glare, while providing a uniform distribution of light, unlike traditional LED luminaires.

  • Patent number: 8979316
    Abstract: A LED array spot illuminator for providing light along an optical axis comprises a substrate and at least one array of multiple LED chips without individual packaging supported by the substrate, wherein the LED chips emit light within the same or different wavelength ranges and are distributed laterally with respect to the axis over a light-emitting area. The LED chips have light emitting surfaces for emitting light in directions transverse to the area. An optical device collects and directs light emitted by the LED chips of the at least one array along the axis. An aperture passes the light emitted by the LED chips of the at least one array along the axis, wherein light collected by the optical device and passed by the aperture forms a beam of light illuminating a spot. Electric current is supplied to the multiple LED chips, causing them to emit light. Light emitted by the multiple LED chips that passed through the optical device and the aperture form a beam of light illuminating a spot.
