Title:
METHOD OF MANUFACTURING FLUORESCENT LAMP AND FLUORESCENT LAMP MANUFACTURED BY ABOVE
Document Type and Number:
Japanese Patent JP2007280967
Kind Code:
A
Abstract:
To provide a method of manufacturing a fluorescent lamp by accurately and reproducibly introducing a small amount of mercury into the fluorescent lamp without using a second component, and to provide a fluorescent lamp manufactured by the method.
A device (73) is formed of a metallic container capable of retaining powder but not completely closed, and contains a TixZryHgzmercury releasing compound, wherein x and y range from 0 to 13, x+y ranges from 3 to 13 and z is 1 or 2. The device (73) is inserted into a tail (71) of a glass tube (70) which is closed at one end and is open at the tail (71) at the other end. Gas for the fluorescent lamp is introduced into the tube (70) from the tail (71), and the tail (71) is pinched off by hot compression between the tail (71) and the device (73). The device (73) is activated by heating to allow release of mercury (76) into the glass tube (70). The tail (71) is subjected to hot compression at a location closer to the tube (70) than the device (73) to make the tube (70) as a closed tube (77). The device (73) is thus enclosed in a glass vial derived from the tail (71), and detached from the tube (70).
