Abstract

PURPOSE:To improve the efficiency and the life of a halide lamp with is 400W class and less, by adjusting the minimum sectional area of a sealing portion formed between the base of a main electrode of the halide lamp and a metallic foil conductor to a predetermined range to the input of the lamp. CONSTITUTION:In a halide lamp which is 400W class and less, enclosing mercury, metal halogenide and rare gas for starting, the area S (lXt)mm.<2> of the minimum sectional part 20 of a sealing portion 2 formed between the base of a main electrode 5 and a metallic foil conductor 3 in a luminous tube 1 is adjusted to 5.6log10P- 4.6<=S<=16.6log10P-13.2 for the power input P(W) of the lamp. Then, the conduction loss of heat is reduced by adjusting thus the area S of the minimum sectional area part 20 of the sealing portion 2 conducting and emitting the heat of the main electrode 5 and the discharge space within the predetermined value. Thereby, the efficiency and the life of the lamp can be improved, and the dispersion of the light color of the lamp can be reduced.
