Patent number: 8246209Abstract: An exemplary illumination device includes a light source and a light-pervious light guiding barrel. The light source is configured for emitting light along a given light path. The light-pervious light guiding barrel receives the light source therein, and the barrel includes light guiding regions with different light directing and/or reflecting capabilities. In addition, the barrel is rotatable relative to the light source such that each of the light guiding regions can be selectively placed on the light path to direct and/or reflect the light from the light source.Type: GrantFiled: December 28, 2009Date of Patent: August 21, 2012Assignee: Foxsemicon Integrated Technology, Inc.Inventor: Chih-Ming Lai

Patent number: 8235554Abstract: 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.Type: GrantFiled: October 16, 2009Date of Patent: August 7, 2012Assignee: Intense Lighting, LLCInventor: Thomas F. Steinkraus

Patent number: 8201980Abstract: 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.Type: GrantFiled: October 21, 2009Date of Patent: June 19, 2012Assignee: Ichikoh Industries, Ltd.Inventors: Yasuhiro Ookubo, Toshiya Abe

Publication number: 20120081902Abstract: 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).Type: ApplicationFiled: September 30, 2010Publication date: April 5, 2012Applicant: OSRAM SYLVANIA Inc.Inventors: Thomas Tessnow, Michael D.

Patent number: 8113691Abstract: 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.Type: GrantFiled: March 11, 2008Date of Patent: February 14, 2012Assignee: ROBE Lighting s.r.o.Inventor: Pavel Jurik

Patent number: 8038282Abstract: 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.Type: GrantFiled: December 7, 2007Date of Patent: October 18, 2011Assignee: Air Motion Systems, Inc.Inventor: Michael L. Claeys
