  • Patent number: 10024513
    Abstract: Provided is a vehicle lamp unit which includes an optical system configured to form a light distribution pattern ahead of a vehicle; and a rotary light shielding member configured to block at least a part of light of a light source. The rotary light shielding member includes a spiral light shielding portion formed to change a blocked quantity of light of the light source as the rotary light shielding member rotates around a rotating axis. The light shielding portion is configured to form a plurality of light distribution patterns such that a position of a cutoff line extending in a direction crossing a horizontal direction changes in the horizontal direction. Further, the light shielding portion is configured such that a change of a position of an edge portion projected as a cutoff line becomes nonlinear in relation to a change of a rotational position of the rotary light shielding member.

    Abstract: A subsystem is disclosed providing a steerable-beam light source. An array of micromechanical reflectors may be disposed to selectively direct portions of light from a light source to selected targets in a scene, such as for providing composed illumination for still or video photography. The array of reflectors may be continuously steerable, thereby achieving more than the mere inefficient patterning of illumination light available from prior art projection approaches, but instead efficiently redirecting light to the desired regions of the scene. The subsystem may be sufficiently compact so as to permit integration with a compact camera into a cellular telephone, a tablet computer, a laptop computer, a digital still-image camera, a digital video-image camera, and so on. The array may be operated in conjunction with a camera controller to selectively illuminate one or more targets of focus or zoom, omit illumination of undesirable image regions, etc.

  • Patent number: 8235554
    Abstract: Provided is a light fixture having a first elongate body defining a mounting surface. A light module is disposed adjacent the mounting surface and includes a module body and a plurality of light emitting devices disposed on the mounting body. The light emitting device defines an emitting axis about which light is emitted. The fixture further includes a first reflector member and a second reflector member disposed on opposed sides of the emitting axis for reflecting light emanated by the light emitting devices. The first reflector member and the second reflector member are pivotable to vary the angle at which light is emitted from the light fixture.

  • Patent number: 8201980
    Abstract: A vehicle headlamp is provided with: a fixed reflector having reflecting surfaces, a respective one of which is made of a parabola-based free curved face; movable reflectors having reflecting surfaces, a respective one of which is made of a parabola-based free curved face; and semiconductor-type light sources, a respective one of which has a light emitting chip shaped like a planar rectangle. When the movable reflectors are positioned in a first location, a light distribution pattern for low beam is obtained on the reflecting surfaces of the fixed reflector. When the movable reflectors are positioned in a second location, light distribution patterns for high beams are obtained on the reflecting surfaces of the fixed reflector and the movable reflector. As a result, the vehicle headlamp enables downsizing, weight reduction, power saving, and cost reduction.

    Abstract: A lighting system (10) comprising a primary light engine (20); a secondary light engine (22); and a projection apparatus (14, 14a-b) comprising a reflector (28) configured to reflect electromagnetic radiation emitted from the primary light engine (20); a projector lens (28) configured to project at least a portion of the reflected electromagnetic radiation from the reflector (28); and a shutter (24, 24a-c) disposed between the secondary light engine (22) and the reflector (28). The shutter (24, 24a-c) is configured to selectively obscure a portion of the projector lens (28) from the reflected electromagnetic radiation and is further configured to selectively emit at least a portion of electromagnetic radiation from the secondary light engine (22) through at least a portion of the projector lens (28).

  • Patent number: 8113691
    Abstract: The present invention provides a drive system for an optical light modulation system employing multiple light modulation element pairs. The each pair is driven by a single motor which drives one axis around which one element of the first pair rotates while the other element of the first pair free floats and rotates about a second axis. While the second axis drives the rotation of the first element of the second pair and the first axis provides a rotation pivot for the second element of the second pair. Thus the two pairs share the two axises providing a more compact drive system that can be used more flexibly in an optical train of an automated multiparameter lighting system.

  • Patent number: 8038282
    Abstract: A UV module of this invention has connection block (optional), connection end cap, shutter, and exhaust end cap assemblies. The connection block has doweled or tapered bayonets for facilitated installation and removal of the UV module. The connection end cap has a drive train with sleeve bearings and/or torque limiting clutches. Each of the sleeve bearing cooperates with a poppet valve in the connection block assembly to assure fluid-tight integrity during assembly and disassembly. Each of the clutches allows for facilitated shutter synchronization and helps prevent drive train breakdown. The shutter assembly may include a novel coolant flow path cross over and/or improved positive and negative positive and negative retainers to eliminate or greatly reduce shutter binding. The shutter end caps may include coolant flow paths and mate with the shutters to achieve a fluid-tight integrity.
