20090079325 | FLUORESCENT LAMP AND PROCESS FOR PRODUCING THE SAME, AND ILLUMINATOR - A fluorescent lamp according to the present invention includes: a glass tube | 03-26-2009 |
20090218927 | FLUORESCENT LAMP, LUMINAIRE AND METHOD FOR MANUFACTURING FLUORESCENT LAMP - A fluorescent lamp is configured so that a glass bulb has a phosphor film formed on its internal face, and a rare gas and an amalgam pellet are enclosed therein. The amalgam pellet contains zinc, tin, and mercury as principal components, one amalgam pellet is enclosed in the glass bulb, and the amalgam pellet has a weight of not more than 20 mg. The fluorescent lamp satisfies the relationship expressed as: 45×(1−A)≦x≦55×(1−A), 75A≦y≦85A, 45−30A≦z≦55−30A, and x+y+z≦100, where x represents a content of zinc contained in the amalgam pellet in percent by weight, y represents a content of tin therein in percent by weight, and z represents a content of mercury therein in percent by weight. This configuration allows the fluorescent lamp to be characterized in that an amount of released mercury that is necessary for the first lighting of the fluorescent lamp is secured, and that the phosphor film is less prone to being peeled due to the amalgam. | 09-03-2009 |
20110068687 | BULB-SHAPED LAMP AND LIGHTING DEVICE - [Problem to be Solved] To provide a bulb-type lamp that can achieve improvement in the heat dissipation properties and size/weight reduction simultaneously, and that can lighten thermal load on a lighting circuit. | 03-24-2011 |
20120002421 | BULB-SHAPED LAMP AND LIGHTING DEVICE - A bulb-type lamp having both heat dissipation and size/weight reduction properties with a lower thermal load on a lighting circuit. An LED module is mounted in a case with a base member to allow dissipation of heat. An LED mount member closes another end of the case and allows conduction of heat to the case. A lighting circuit receives power via the base member. The lighting circuit is disposed inside a circuit holder. An air space exists between the circuit holder and both the case and the mount member. The lighting circuit is isolated from the air space by the circuit holder. A relationship 0.5≦S | 01-05-2012 |

20120155061 | LED MODULE, LED LAMP, AND ILLUMINATING APPARATUS - To constrain reductions in luminous efficacy while enhancing the color rendition index, the LED module includes a blue LED, at least one variety of phosphor particles excited by the outgoing light from the blue LED, and neodymium glass particles that include neodymium ions absorbing the outgoing light from the phosphor particles in a predetermined wavelength band. | 06-21-2012 |
20120300432 | LED LAMP, LED ILLUMINATION DEVICE, AND LED MODULE - An LED lamp provides a strong red color with a natural appearance. The LED lamp is provided with an LED module and a filter. The LED module includes a blue LED with a main emission peak in the 440 nm to 460 nm wavelength band, a green/yellow phosphor that is excited by light emitted by the blue LED, and a red phosphor that is excited by light emitted by at least one of the blue LED and the green/yellow phosphor. The filter reduces the spectral radiation intensity of at least a portion of the 570 nm to 590 nm wavelength band among light emitted by the LED module. | 11-29-2012 |
