Patent number: 8702289Abstract: A lighting unit can form a plurality of light distribution patterns without use of a shield and without an act of shielding light from a light source. The lighting unit can include a laser diode, a fluorescent member with a fluorescent portion configured to receive blue light from the laser diode and emit white light, and a projector type lens configured to project the white light. The fluorescent member can be rotated around a rotation shaft perpendicular to the optical axis of the projector type lens and shaped such that when the fluorescent member is rotated by a predetermined angle by the driving member and viewed from the projector type lens, a plurality of contours of the fluorescent portion can be changed according to the predetermined angle.Type: GrantFiled: October 31, 2011Date of Patent: April 22, 2014Assignee: Stanley Electric Co., Ltd.Inventors: Takashi Sato, Takao Saito

Patent number: 8672514Abstract: In one aspect, a lighting system is disclosed that includes an inner reflector extending from a proximal end to a distal end along an axis, where the proximal end is adapted to receive light from a light source and the distal end provides an exit opening (aperture) for the received light. The system can further include an outer reflector that is axially positioned relative to the inner reflector. The inner and outer reflectors are coupled for axial movement relative to one another to change the flood spread of the light exiting the lighting system.Type: GrantFiled: January 17, 2012Date of Patent: March 18, 2014Assignee: Fraen CorporationInventors: John R. Householder, Carlton S. Jones

Patent number: 8672496Abstract: A mirror ball adapted to engage the socket of a ceiling mounted electric light fixture in order to be suspended and powered therefrom. A tubular stem having a proximal portion threaded in the manner of an Edision screw is provided extending downward from the fixture to a lower base. A lightweight mirrored sphere or globe having a void through its (vertical) polar axis is rotatably engaged on the stem and retained in place by the lower base which houses power systems, a controller and a motor engaged to an annular gear at the lower pole of the mirrored sphere in order to slowly rotate the globe. A power supply is used to reduce line voltage to 12 v DC to drive the motor and operate one or more LED lighting elements directed at the mirrored surface and mounted at the ends of one or more arms radiating from the lower housing.Type: GrantFiled: April 20, 2012Date of Patent: March 18, 2014Inventor: Mona O'Kane

Publication number: 20140071697Abstract: The invention relates to a folding reflector (1) having shade spokes (5) that are annularly hinged on a bearing body (7), by which spokes a reflecting cover (3) can be mounted. The reflector is characterized in that the ends of the shade spokes (5) that turned toward the linkage thereof extend beyond said linkage respectively and in that, due to the effect on said sections (9) of the shade spokes (5) extending beyond the linkage, said sections can be moved into the mounting position and back.Type: ApplicationFiled: March 6, 2012Publication date: March 13, 2014Applicant: BRON ELECTRONIK AGInventor: Francois Portmann

Publication number: 20140022794Abstract: A novel lens arrangement features a first lens which is configured to be fixed to a light source and features an aspherical convex exit surface for transmitting light which received from the light source. A second lens is arranged to the optical axis of the first lens and features an aspherical concave entry surface which is arranged to receive light which transmitted by the first lens and which has substantially the same shape as that of the exit convex surface of the first lens. The first and second lens are configured to be moved along the optical axis in respect to each other between a minimum extended position, wherein the exit surface of the first lens is nested into the matching concave entry surface of the second lens, and maximum extended position, wherein second lens lies at the focal point of the first lens.Type: ApplicationFiled: July 20, 2012Publication date: January 23, 2014Applicant: LEDIL OYInventor: Petri Laukkanen

Patent number: 8628224Abstract: An articulating accessory cartridge for use in theatrical and commercial lighting fixtures in which optical accessories are utilized. The cartridge includes an outer member removably insertable in the fixture and an inner member telescopically retained in the outer member. One or several optical accessories can be removably received and retained in the inner member in an axial stack, depending upon effects desired. The inner cartridge member is telescopically extended before the cartridge is mounted on the fixture. As the cartridge is inserted, the uppermost accessory engages the end of a reflector associated with a light source in the fixture. Continued insertion of the cartridge results in telescopic retraction of the inner cartridge member, depending upon the number of accessories in the stack, until the outer cartridge member is fully seated. The accessories are held against the end of the reflector for optimal efficiency of the lighting and lighting effects.Type: GrantFiled: October 27, 2011Date of Patent: January 14, 2014Assignee: Lighting Services, Inc.Inventors: John Speidel, Vincent Gennarelli, Frank Reidmiller, Peter Eagleton, Jose Cadena, Scott Wisniewski
