Patent number: 7839069Abstract: The orientation of fluorescent lamps is detected in a manufacturing method for a direct backlight unit that alternates orientations of adjacent fluorescent lamps. In a preparation step of the manufacturing method for the backlight unit of the present invention, a plurality of fluorescent lamps are prepared. In each of the fluorescent lamps, a length (a1) from a first sealed portion of a glass bulb (26) to a non-phosphor layer (32) area is shorter than a length (a2) from a second sealed portion to a non-phosphor layer (32) area (a1<a2). In a detection step, the difference between the lengths is detected with use of a sensor. In an installation step, the fluorescent lamps are arranged with use of the detection results so that the first and second ends alternate on a same side of a housing.Type: GrantFiled: February 21, 2007Date of Patent: November 23, 2010Assignee: Panasonic CorporationInventors: Akiko Nakanishi, Taizou Ono, Hirofumi Yamashita, Kazuhiro Kumada, Haruo Yamazaki, Shinji Kihara, Akio Kitada, Masanobu Murakami, Tomokazu Matsuura, Hiroshi Sakurai, Makoto Yokozeki, Takashi Maniwa, Shigeru Ido

Publication number: 20090096958Abstract: A cold cathode fluorescent lamp includes a glass bulb (16), a protective film (22) formed on an inner face of the glass bulb, and a phosphor layer (24) that overlaps the protective film and that contains blue phosphor particles (26B), green phosphor particles (26) and red phosphor particles (26). The glass bulb has been formed from soda glass, and the blue phosphor particles have been coated with a metal oxide (30). Also, the protective film is made of silica (SiO2). Since the protective film has been provided in the fluorescent lamp and since the blue phosphor particles, which readily deteriorate, have been coated with the metal oxide, a good luminance maintenance rate is obtained. In addition, although the glass bulb of the fluorescent lamp is made of soda glass, since the protective film is made of silica, the fluorescent lamp obtains an initial luminance equivalent to the initial luminance of a fluorescent lamp whose glass bulb is made of borosilicate glass.Type: ApplicationFiled: March 23, 2007Publication date: April 16, 2009Inventors: Tomokazu Matsuura, Akiko Nakanishi, Hideki Wada, Akio Kitada, Masanobu Murakami, Hiroshi Sakurai, Takashi Maniwa, Kazuhiro Kumada, Shigeru Ido, Makoto Yokozeki, Nozomu Hashimoto

Publication number: 20080191620Abstract: A light emitting device, with which the luminous efficiency is improved and the color non-uniformity of the emitted light is lessened. Specifically, a light emitting diode element is covered with a diffusing layer, with which a diffusing agent is added to a resin. A phosphor layer, with which a phosphor is added to a resin, is disposed on top of the diffusing layer. The light from the light emitting diode element is diffused by the diffusing layer. By exciting the phosphor layer with the light diffused by the diffusing layer and thereby making the phosphor layer emit light, the luminous efficiency is improved and the color non-uniformity is lessened.Type: ApplicationFiled: March 23, 2005Publication date: August 14, 2008Applicant: Toshiba Lighting & Technology Corp.Inventors: Takayoshi Moriyama, Akiko Nakanishi, Masami Iwamoto, Shinji Nogi, Kozo Ogawa, Keiichi Shimizu, Akiko Saitou, Seiko Kawashima, Tomohiro Sanpei, Masahiro Izumi, Masahiro Toda

Patent number: 7394189Abstract: An objective is to provide a compact self-ballasted fluorescent lamp which can reduce occurrence of a short circuit without protecting lead wires extending from each end portion of a spiral arc tube. To achieve the objective, a pair of connection pins is provided on a circuit board of the compact self-ballasted fluorescent lamp, near a periphery of the circuit board so as to oppose another pair of connection pins formed near the periphery. In this way, the pairs of connection pins can be respectively provided directly above the end portions of the spiral arc tube. Thus, lead wires extending from each of the end portions can be connected to a corresponding one of the pairs of connection pins with a relatively short distance. This prevents the lead wires from being in contact with the circuit board, thereby reducing occurrence of a short circuit.Type: GrantFiled: March 28, 2003Date of Patent: July 1, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hiroki Kitagawa, Shiro Iida, Akiko Nakanishi, Yasushige Tomiyoshi, Toshikatsu Kotaki

Patent number: 7321190Abstract: An arc tube is formed by a glass tube that is turned at a substantially middle thereof and wound around a spiral axis from the middle, to have a double-spiral structure. End portions of the arc tub are wound around the spiral axis. A holder has insertion openings formed therein in such shapes that correspond to shapes of the ends of the arc tube. The insertion openings allow the ends of the arc tube to be inserted along a bottom wall of the holder. The holder also includes guide grooves provided in the areas before the insertion openings in the spiral direction of the ends of the arc tube. The guide grooves allow the end portions of the arc tube to come in contact, and when the arc tube is rotated around the axis, guide the ends of the arc tube to the insertion openings.Type: GrantFiled: July 22, 2003Date of Patent: January 22, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Akiko Nakanishi, Yoshinori Kakuno, Shiro Iida, Kenji Itaya

Patent number: 7298088Abstract: This invention aims at providing a low-pressure mercury lamp having an improved luminous efficiency while maintaining the compactness and long life of the arc tube. This lamp comprises an arc tube formed by bending a glass tube. This arc tube is formed into a double-spiral structure comprising: a turning part located in substantially the midsection from both ends of the glass tube; a first spiral part starting from one of the ends and spiraling around the pivotal axis to reach the turning part; and a second spiral part starting from the turning part and spiraling around the pivotal axis to the other end. The glass tube has a circular shape in cross section with 7.4 mm inner diameter. This low-pressure mercury lamp is a 12 W lamp alternative to a 60 W incandescent lamp, and the bulb wall loading under steady state illumination is set at 0.103 W/cm2.Type: GrantFiled: March 17, 2003Date of Patent: November 20, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Shiro Iida, Akiko Nakanishi
