| 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 |

The second configuration of the main body allows for controlled placement and immobilization of the device within the discharge tube when the shape memory alloy is raised above the alloy transition temperature. The device is shaped in a generally planar or non-planar configuration. | 05-16-2013 |

The diffuse reflection layer reflects the visible light and the ultrared ray back to the annularly airtight gas discharging cavity, so that the visible light and the ultrared ray are leaked out of the external surface of the glass bulb. Thereby, the original visible light unable to be used becomes usable, so that the illuminant efficiency is promoted, the operating temperature is decreased, and the using life is extended. | 07-18-2013 |
