Abstract
PURPOSE:To prevent colour change deterioration due to pit phenomenon by forming thicker the upper part of the Nesa film in a glass bulb than the lower part and forming thinner the upper part of the phosphor film than the lower part and turning on the lamp in this state. CONSTITUTION:The thickness of the Nesa film 2 is coated on the inner surface of a bulb thicker than the lower part 1b so that the resistance of the Nesa film 2 reduces smaller at the upper part 1a in the section of a glass bulb 1. The phosphor film 3 which is coated over the film described above is thinner in the upper part and thicker in the lower part. Due to this difference in thickness, the upper part 1a and the lower part 1b and distinguished, and in use, the lamp is lighted up, keeping the upper part 1a.
