Summary:PROBLEM TO BE SOLVED: To provide a fluorescent lamp with improved life. SOLUTION: This fluorescent lamp 10 is formed by winding a coil 30 using first, second, and third materials 45, 46 and 50. The third mandrel has a diameter of at least 1.0 mm. The coil is wound around the second mandrel to provide at least 80 turns per inch (TPI). The third mandrel is larger than in conventional coils, allowing about 50% more electron emitter material 32 than can be loaded on a conventional coil. This has been found to lead to substantially increased lamp life, about 50% longer for a diameter of 1.25 mm than for a coil with a diameter of about 0.86 mm. COPYRIGHT: (C)2003,JPO
