Abstract

PURPOSE:To make it possible to light a lamp stably without lowering luminous intensity after lighting and without needing time until it reaches the normal lighting condition by arranging the shape of a lamp bulb that the sectional area of a coil arranging part for applying electromagnetic field may be the maximum. CONSTITUTION:A lamp bulb 1 is formed of translucent quartz and rare gas and luminous substance are charged inside it, and a coil 2 for applying electromagnetic field is wound round the periphery of a part where the sectional area of the bulb 1 becomes maximum. By putting A part and B part closer to each other, which become positions farthest from a part where high frequency energy is input into a lamp bulb 1, like this, the tube wall temperature of A part and B part can be elevated higher and vapored luminous substance can be prevented from condensing. Accordingly, the lamp lights up stably without lowering the luminous intensity after lamp lighting-up and without needing time until it reaches the normal lighting condition.
