Patent number: 7090382Abstract: A modular pole system and light fixture is disclosed including an internal skeletal structure and an external plastic shell. The external plastic shell may slide over the assembled internal skeletal structure and may be a singular unit. The internal skeletal structure may be an upwardly extending tapered pole which is held in place by a base and post which also provides a static structure acting as a passive defense mechanism.Type: GrantFiled: February 7, 2005Date of Patent: August 15, 2006Assignee: Genlyte Thomas Group LLCInventors: Eric O. M. Haddad, Donald Fentress

Patent number: 6965195Abstract: A cover member is adhered onto a substrate on which an EL element is formed with a filler as an adhesive. Further, a sealing member is provided so as to cover a side surface (an exposing surface) of the filler, and a frame member is adhered using the sealing member. With this structure, the EL element is completely sealed by the filler, and shut from moisture and the like from the outside. Thus, deterioration of an EL layer due to oxidization can be prevented.Type: GrantFiled: February 15, 2001Date of Patent: November 15, 2005Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Shunpei Yamazaki, Yasuyuki Arai, Mayumi Mizukami

Patent number: 6955449Abstract: A LED symbol signal with LEDs arrayed to correspond to a desired symbol. A mask defines the desired symbol. A diffusion surface on the cover diffuses the display aspect, obscuring the individual LEDs. The mask is spaced a distance from the diffusing surface. The more aggressive the diffusion pattern the closer the mask is spaced to the diffusion pattern. Preferably, the ratio of the pitch of the optical elements to the width of the symbol at the diffusion surface is less than 1:2, preferably less than 1:4, more preferably less than 1:6 and most preferably approximately 1:10.Type: GrantFiled: March 13, 2003Date of Patent: October 18, 2005Assignee: GELcore LLCInventor: Patrick Martineau

Patent number: 6830364Abstract: A vehicle light assembly includes a reflector having apertures formed in a circumferential wall thereof which are configured to accept light emitting diodes therethrough in an orientation generally perpendicular to the circumferential wall. The reflector includes a reflective protuberance, which is typically multi-faceted, extending upwardly from an interior surface of the reflector and generally centered with respect to the light emitting diodes. Each facet of the protuberance directs light from the light emitting diodes to an upper lens. Multiple ridges extend upwardly from the interior surface of the reflector at approximately forty-five degree angles with respect to the light emitting diodes for directing the light emitted from the light emitting diodes to the lens. The configuration of the reflector enables the use of fewer light emitting diodes.Type: GrantFiled: March 5, 2003Date of Patent: December 14, 2004Inventor: Zorak Ter-Oganesian

Patent number: 6821002Abstract: This invention combines a lampbox and lampshade. The lampbox lampshade provides a uniform illumination for the transmitted light viewing of photographic slides removably attached to the outside of the lampshade. Optimum viewing conditions are insured by the fact that no surfaces are interspersed between the surface of the slides and the eye of the viewer. The normal functions of a lampshade are not affected.Type: GrantFiled: April 28, 2003Date of Patent: November 23, 2004Inventor: Paula A. K. Morgen

Patent number: 6808289Abstract: A flexible light emitting diode (LED) lamp. The flexible LED lamp includes a base, an LED lamp head, and a flexible mid region disposed between the base and the LED lamp head. The LED lamp head is detachable or replaceable to obtain different colors, upgrade to improved LED lighting technology, or replace a defective component. The LED lamp head includes one or more LEDs coupled to a printed circuit board and a lens to spread the light generated by the LEDs to provide a larger area of illumination. The base of the flexible LED lamp has a clip to couple an object, such as a music stand, table or a book case. The flexible mid region allows the LED lamp head to be moved into a position where illumination is desired.Type: GrantFiled: June 12, 2002Date of Patent: October 26, 2004Assignee: RPM Optoelectronics, LLCInventor: David Reed

Patent number: 6796680Abstract: A strip lighting device includes an elongate housing, a plurality of light sources arranged at intervals within the housing, and a fastener for fastening the elongate housing to a surface. The elongate housing overlies the plurality of light sources and diffuses, disperses or scatters light from the light sources such that individuals of the plurality of light sources are substantially not distinguishable when the housing is viewed from the outside.Type: GrantFiled: January 28, 2000Date of Patent: September 28, 2004Assignee: Lumileds Lighting U.S., LLCInventors: David Field Showers, James Berry Quantrell, Kenneth Robert Goddard, Malcolm Wesley Oldis

Patent number: 6752523Abstract: A vehicle lamp that uses a special LED made of: translucent block body, an LED chip embedded in the translucent block body, a semi-spherical shape condenser lens provided on the front end surface of the translucent block body and positioned in front of the LED chip, and a reflector provided inside the translucent block body and forwardly reflects the light from the LED chip. The vehicle lamp includes a front lens disposed in front of the special LED so that the front lens is positioned where the direct light from the LED chip and the reflection light reflected by the reflector start to intersect with each other.Type: GrantFiled: October 22, 2002Date of Patent: June 22, 2004Assignee: Koito Manufacturing Co., Ltd.Inventor: Daisuke Takahashi
