Patent number: 7364312Abstract: A light source lamp, in which reduction of the available amount of illumination light on an illuminated region side can be reduced or suppressed, heightens light utilizing efficiency. The light source lamp has a light emitting tube having a luminous part in which a pair of electrodes arranged along an illumination light axis are built, an ellipsoidal reflector which reflects light from the luminous part and emits its reflection light as illumination light to an illuminated region side, and an auxiliary mirror which is arranged on the illuminated region side of the luminous part, has a reflection concave surface of a nearly hemispherical shape, and reflects the light from the luminous part on the ellipsoidal reflector. A center Q of curvature of the auxiliary mirror is arranged in a position distant from a center P of the luminous part to the illuminated region side along the illumination light axis.Type: GrantFiled: December 1, 2004Date of Patent: April 29, 2008Assignee: Seiko Epson CorporationInventor: Koichi Akiyama

Patent number: 7364314Abstract: Optical structures and methods for manufacturing the same includes, in one embodiment, a substrate and a plurality of two-sided optical components disposed along the substrate. Each component includes optical microstructures on each side. At least a portion of one side of at least some of the components is air-backed and the other side of the at least some of the components is substantially wetted-out by a material. Retroreflective optical structures, threads, or fibers and manufacturing methods for forming same are also provided. Optical structures are provided that include a plurality of microstructures enclosed within an outer layer that is formed from a single substrate. An apparatus and method are also provided for forming an optical structure comprising injecting a material into a mold to form the optical structure, forming the optical structure into a desired geometric shape, and sealing ends of the optical structure.Type: GrantFiled: December 9, 2003Date of Patent: April 29, 2008Assignee: Reflexite CorporationInventors: Robert B. Nilsen, William P. Rowland

Patent number: 7364315Abstract: A tubular Electro-Luminescent light device offers desired bending directions with super brightness based on the predetermined width of a panel incorporated with a proper inverter system. The panel has a much narrower width than a tube means containing the panel to allow the panel to bend in any direction and angle within the tube means to provide desired light effects. The panel can be flat or twisted within the tube means, which in turn may have a desired colored, transparency, wall thickness, diameter, shape, or length. The device may incorporate non-elastic means, magnetic means, a tube holder, sensor means, and/or integrated circuit to add a wide variety of features.Type: GrantFiled: June 14, 2002Date of Patent: April 29, 2008Inventor: Tseng-Lu Chien

Patent number: 7364317Abstract: In an object verifier having a housing and an object holder, an object may be placed in the object holder for observation by an operator. The object is illuminated using a collimated beam of white light that is generated by a light generator. The collimated beam of white light is passed through a beam splitter with the two portions of the collimated beam of white light presented to the object at a 90 degree angle one from the other. The interior of the housing includes a reflective surface for maximal illumination of the object. The observer may view the illuminated object through a viewing window and/or through a magnification window. The magnification window provides for the viewing of the object in greater detail.Type: GrantFiled: December 8, 2005Date of Patent: April 29, 2008Inventors: Joel N. Bock, Ronald R. Erickson, Eliezer D. Sandler

Patent number: 7364319Abstract: A personal light including a battery power source connected in series with a light-emitting diode (LED) light source and a switching mechanism configured for non-contact actuation are disposed within an environmentally sealed chamber. A reflector is employed to maximize reflection of light emanating from the LED and a lens having an anti-reflective coating thereon associated with the LED opposite the reflector to enhance the light output and magnify the narrow beam of the LED. The switch employs an actuation mechanism exterior to the chamber to activate and deactivate the light.Type: GrantFiled: October 6, 2005Date of Patent: April 29, 2008Inventor: Robert L. Canella

Patent number: 7364320Abstract: A handheld flashlight includes a head that pivots relative to a body. Three legs pivotally connect to the body and open into a tripod to support the head in an elevated position. The legs are spring-biased toward the open tripod position and are selectively held closed by a detent mechanism. In the closed position, the legs form a flashlight handle that is aligned with an illumination direction of the head and is shaped and sized to be held in the hand of an operator. Each of the three legs contain battery source holders for battery sources that connect to each other in parallel. Diodes are disposed in series with each battery source to prevent the parallel battery sources from discharging each other.Type: GrantFiled: April 7, 2006Date of Patent: April 29, 2008Assignee: The Stanley WorksInventors: Gary Van Deursen, Joseph Martone, Vincent Cook, Michael Kwok Ying Chan
