Patent number: 8344993Abstract: A backlight device for LCD displays can include a light-emitting source of the type that includes a cold-cathode or hot-cathode fluorescent tube that is lit with a high-frequency power supply. The high-frequency power supply can be PWM-controlled to adjust the brightness. The high-frequency power supply can also be randomly phase-modulated with an irregular modulation code to light the fluorescent tube. This enables the infrared radiation from the fluorescent tube to be spread over a wider band such that the level thereof is lowered to a level that does not interfere with typical remote controls.Type: GrantFiled: August 10, 2007Date of Patent: January 1, 2013Assignee: Stanley Electric Co., Ltd.Inventors: Masayuki Kanechika, Junji Matsuda

Patent number: 8022342Abstract: A microwave source system 1 extracts power in a predetermined microwave frequency band out of thermal noise power generated by a resistor (3) by using filter means (4), amplifies the power through a first amplifier (5) and a second amplifier (7), and outputs the power. The first amplifier (5) is variably controllable in gain and control means (6) controls the gain in such a way as to maintain the intensity of the microwave power output from the first amplifier 5 at a predetermined constant value. The second amplifier (7) has a predetermined gain. The resistor (3) is attached to one of the first amplifier (5) and the second amplifier (7), for example, to the second amplifier (7). Thereby, the resistor (3) receives heat from the amplifier (7). Output of the microwave source system (1) is supplied to, for example, a microwave discharge lamp (2). The microwave source system (1) having the above configuration can be compact and inexpensive without a need for a magnetron or a high voltage power supply.Type: GrantFiled: February 27, 2007Date of Patent: September 20, 2011Assignee: Stanley Electric Co., Ltd.Inventor: Masayuki Kanechika

Patent number: 7868530Abstract: The disclosed subject matter includes a filament electrode that can include a filament coil connected with a pair of lead wires with confidence. It is possible for a fluorescent lamp using the filament electrode to emit light with a wider range while located in a thin tube. The filament electrode can include a pair of connecting pipes, a pair of lead wires located parallel to each other, and a filament coil including two connecting parts. Each of the two connecting parts of the filament coil can attach to respective ends of the pair of lead wires via the pair of connecting pipes via pressure bonding so as not to contact the connecting parts of the filament coil with the ends of the pair of lead wires located in the pair of connecting pipes and so as to align the structures. Thus, the filament electrode can be used even in a thin glass or quartz tube and can provide an effective heat-shield operation.Type: GrantFiled: December 27, 2007Date of Patent: January 11, 2011Assignee: Stanley Electric Co., Ltd.Inventors: Toshiyuki Nagahara, Koji Kikuchihara, Masayuki Kanechika

Patent number: 7775847Abstract: A method for manufacturing a hot cathode fluorescent lamp can ensure or facilitate stable initial luminous intensity and provide improved product life characteristics even when the hot cathode fluorescent lamp employs a glass tube with an outer diameter of less than 7 mm?. One end of a glass tube can be sealed with a glass bead of a mount structure. The other opening end of the glass tube can be welded with an opening end of an exhaust pipe with bent portions of lead wires being sandwiched between the opening ends of the glass tube and the exhaust pipe. After evacuating a vacuum system that is constituted by the inner spaces of the glass tube and the exhausted pipe communicating with each other, the bent portions of the lead wires which extrude outside the vacuum system can be clamp-connected to power source lines extending from an external power source. The emitter of the filaments can be activated by the generated heat of the filament.Type: GrantFiled: September 14, 2007Date of Patent: August 17, 2010Assignee: Stanley Electric Co., Ltd.Inventors: Naoyuki Matsubara, Masayuki Kanechika, Yoshifumi Takao, Kazuhiro Miyamoto, Toshiyuki Nagahara, Junji Matsuda

Patent number: 7447249Abstract: A lighting system includes a microwave resonator (2) for generating a standing microwave in the internal space, and a gas cell (6) enclosing a medium is disposed in the internal space of the microwave resonator 2. The lighting system excites the medium in the gas cell (6) by the standing microwave to generate light. The gas cell (6) is replaceably mounted on the microwave resonator (2).
