Patent number: 7244045Abstract: An illuminated novelty device includes a plurality of light emitting diodes (LEDs). An elongated light bar can be mounted to each of the LEDs. The light bars have a light receiving end and a light emitting end and are mounted to respective LEDs at the light receiving end. The light bars are formed from a light transmissive material. Conductors extend between and connect the LEDs. The LEDs are spaced from one another along the length of the conductors. The LEDs, the elongated light bars and the conductors define an LED assembly. A power source is operably connected to the LED assembly and a switch is operably connected between the power source and the LED assembly. The power source and switch are maintained in a housing. A light transmissive sheath has the LED assembly fitted, at least in part, within it. The sheath has a first end mounted to the housing and a second free end.Type: GrantFiled: May 17, 2005Date of Patent: July 17, 2007Assignee: Chemical Light, Inc.Inventors: Michael L. Schrimmer, Ronald E. Gilley, Ching-Hui Lee

Patent number: 7232240Abstract: An apparatus provides a safer, high brightness glare or illumination source. The apparatus comprises a laser to emit a light beam, and a magnifying telescope, including a negative lens to expand the light beam and a positive lens to collimate the expanded light beam. The apparatus also includes a holographic diffuser to receive the collimated light beam and to produce a diffused light beam. The diffused light beam has an extended cross section and provides an extended glare source at increased power down range.Type: GrantFiled: May 6, 2005Date of Patent: June 19, 2007Assignee: Northrop Grumann CorporationInventors: William D. Kosnik, Brenda J. Novar, Victor I. Villavicencio

Patent number: 7222987Abstract: A connector for connecting a plurality of light strings mainly includes a female socket and a male socket with a plurality of terminal receivers and conductive pieces respectively. The terminal receivers and the conductive pieces are connected with the light-string conducting wires or the control lines of the light strings. Thereby when the male/female sockets are joined together, the light string can be extended or a working module controller for the light string can control more light-strings. The female socket includes a waterproof stopper inside to stabilize the conducting wires going through the female socket and also to provide a waterproof function. A joint nut is set outside of the male socket to reciprocally join with the female socket, so that the male/female sockets will not separate from each other arbitrarily.Type: GrantFiled: May 13, 2005Date of Patent: May 29, 2007Inventor: Wei-Jen Tseng

Patent number: 7195374Abstract: A luminaire for distributing light rays from a light source may include a region configured to contain a lamp. The region may extend along a longitudinal axis of the luminaire. The luminaire may include first and second reflector portions disposed along the longitudinal axis. The first reflector portion may be configured to direct light rays in a direction away from the ceiling, and the second reflector portion may be configured to direct light rays in a direction toward the ceiling. The light source may be between the second reflector portion and the ceiling, with the second reflector portion defining a cusp disposed at a first side of the light source. The first reflector portion may extend through the second reflector portion and beyond the light source to a second side of the light source opposite to the first side.Type: GrantFiled: March 11, 2005Date of Patent: March 27, 2007Assignee: Honeywell International, Inc.Inventors: Robert J. Saccomanno, Ivan B. Steiner

Patent number: 7118265Abstract: Disclosed are an optical member (100), a backlight assembly (500) and a liquid crystal display device (800) using the optical member. The optical member (100) includes an optical body (110) and a first fixing part (120). The optical body varies optical characteristic of first light incident into thereto to exit a second light. The first fixing part (120) is protruded from at least one side face of the optical body (110), and including a fixing hole (122) and a vibration attenuating means (124). The fixing hole (122) is elongated in a main expansion direction of the optical body (110), and the vibration attenuating means (124) is formed on an inner of the fixing hole to attenuate external vibration applied to the optical body (110). The fixing hole (122) allows movement of the optical member (100) in accordance with expansion of the optical member (100) caused by heat, thereby preventing wrinkles from being created on the optical body.Type: GrantFiled: December 30, 2002Date of Patent: October 10, 2006Assignee: Samsung Electronics Co., Ltd.Inventor: Chun-Hyun Cho
