Patent number: 7241021Abstract: An emergency information lighting system (100/200/300), comprising a primary light source (110/210/310) and a housing (112/212/312) for the primary light source (110/210). The housing (112/212/312) includes a first wall (120/220/320) with indicia openings (126/226/326) which correspond to emergency information. The primary light source (110/210/310) emits primary light, which passes through the indica openings (126/226/326) to display the emergency information to a viewing environment. The housing (112/212) or a bulb (316) incorporates a phosphorescent material (132/232/332) which, in the absence of the primary light, emits passive light to display the emergency information to the viewing environment.Type: GrantFiled: February 10, 2005Date of Patent: July 10, 2007Assignee: Avery Dennison CorporationInventor: Michael E. Hannington

Patent number: 7226195Abstract: A compact and cost-efficient lamp assembly includes cold-cathode fluorescent lamps in a variety of edge-lit display sign applications specifically, in edge-lit emergency lighting signs. The lamp assembly includes in one self-contained module a lower housing unit and an upper housing unit shaped to cover the lower housing unit. The lower housing unit is divided into a lower frame and an upper frame disposed on top of the lower frame. The upper frame has at least two inverters disposed within. The lower frame is a parabolic shape reflector frame supporting at least two cathode lamps in line with the two inverters, each of which is connected to each lamp for providing high voltage to power up the lamps. Additionally, an edge-lit panel having a front and back side is disclosed in the present invention. The backside includes a semi-transparent frosted surface with a white opaque lamination glued on the frosted surface.Type: GrantFiled: July 23, 2004Date of Patent: June 5, 2007Assignee: Thomas & Betts InternationalInventors: Radu C. Rapeanu, Viorel Mirica, Zhigang Xing, David Blier

Patent number: 7204050Abstract: An exit device includes an electroluminescent exit sign assembly, preferably mounted on a push rail actuator of the exit device. An electroluminescent illuminator, an opaque material and a transparent protective cover form the electroluminescent sign assembly. The push rail actuator operates a latch mechanism and opens an associated exit door when pressure is applied. An inverter may be located within the exit device to power the electroluminescent illuminator with an AC or voltage. The electroluminescent sign assembly is preferably removable for repair or replacement without removing the exit device from the exit door and is located within a surface cavity in an electrically insulating touchpad on the exit device actuator. Additional transparent nonconductive material surrounds the electroluminescent material to provide further electrical insulation.Type: GrantFiled: December 29, 2003Date of Patent: April 17, 2007Assignee: Sargent Manufacturing CompanyInventors: Thanasis Molokotos, Daniel J Picard

Patent number: 7114840Abstract: An exit sign comprising a housing and a plurality of red and green color LEDs having the capability of being selectively activated to produce either red light or green light. The plurality of LEDs are mounted in a mutual lighting association in the housing. A switch is manually operable to selectively activate the plurality of red color LEDs to produce the red light and in the alternative, to selectively activate of the plurality of the green color LEDs to produce the green light. Means for passing light from the selected red light or selected green light in the form of indicia symbolizing an exit enables viewing by an observer, such means include a stencil having four independent letters forming the word EXIT. DC circuitry is in operative electrical connection with the plurality of LEDs. A source of DC electrical power activates the DC circuitry.Type: GrantFiled: January 23, 2004Date of Patent: October 3, 2006Inventor: Douglas Hamrick

Patent number: 7047679Abstract: A mold for stepwise molding, using two different plastics, signage composed of a plurality of symbols surrounded by a continuous matrix including a first mold member having a first cavity defining surface including at least one first gate for admitting a first plastic, and a second mold member movable with respect to the first mold member having a second cavity defining surface confronting the first cavity defining surface. The cavity defining surfaces are spaced from each other by a predetermined distance to define a first cavity receiving the first plastic. The second mold includes lateral surfaces defining at least some of the plurality of symbols. At least one second gate is provided in the first mold member, each second gate admitting a second plastic only when a second cavity is defined so that at least a portion of the lateral surfaces defining at least some of said plurality of symbols are retained in position as the second plastic is injected.Type: GrantFiled: October 28, 2002Date of Patent: May 23, 2006Assignee: L. L. Culmat, L.P.Inventors: J. Larry Underwood, Ricky W. Tumlin
