Patent number: 6886962Abstract: In a shielded reflective LED, each of light sources can be surface-mounted substantially without being influenced by heat distortion based on the difference in thermal expansion coefficient between resin and metal because the light source is so small-sized that only one light-emitting element is sealed with a resin. Moreover, variations in luminous intensity and chromaticity of each of light-emitting elements used in three-color light sources can be examined in advance. Hence, well-matched three-color light sources can be mounted in combination so that display unevenness of a full color display can be reduced greatly. Further, the surface of the substrate portion on which the light source is fixed is silk-screen-printed in black. Hence, external light which enters the device through the optical opening portion when the device is turned off is reflected by the reflecting mirror and absorbed to the surface of the substrate portion.Type: GrantFiled: June 26, 2002Date of Patent: May 3, 2005Assignee: Toyoda Gosei Co., Ltd.Inventor: Yoshinobu Suehiro

Patent number: 6851832Abstract: LED tube light housings configured to control and orient the lateral position of inserted LEDs on a wiring harness. An LED tube light housing includes a first end, a second end, an inner surface, and an outer surface. First and second sections are generally formed inside the housing. The first section is configured in the form of a cavity for providing a vertical orientation of one or more LEDs. At least the top of the first section, e.g., the cavity, is transparent, translucent, or the like, to permit light emitted from LEDs contained therein to pass therethrough. The remaining portion of the housing may be transparent, translucent, opaque, or a combination thereof. The second section is configured to contain therein electrical components of the wiring harness. No printed circuit board portions are included in the wiring harness.Type: GrantFiled: May 21, 2002Date of Patent: February 8, 2005Inventor: Dwayne A. Tieszen

Patent number: 6851835Abstract: A light assembly is configured to produce a large area of light emission from an LED light source. The LED light source is mounted within a concave reflector and oriented to face the rear of the reflector. A compound reflecting surface diverts axial light from the LED away from the axis of the reflector to avoid blockage by the LED support structure. A peripheral reflecting surface redirects the diverted light. The LED light source may be a linear array of LEDs aligned with a linear focal axis of the reflector.Type: GrantFiled: December 17, 2002Date of Patent: February 8, 2005Assignee: Whelen Engineering Company, Inc.Inventors: Todd J. Smith, Jon H. Lyons
