Abstract
PURPOSE: To make uniform the luminous intensity in the axial direction of the lamp, by sealing up in the lamp a gallium halide which emits a spectrum corresponding to the spectral sensitivity of photosensitive paper for copying.
CONSTITUTION: A luminous tube 1 is fixed in an outer tube 6 by luminous tube fixing spacers 12, bases 7, base fixing spacers 13, base clamp bands 10 and fitting screws 11. The distance between electrodes is ten or more times larger than the inner diameter of the luminous tube 1. 0.06 mg of a halide of gallium and a halide of at least one of magnesium, lead, bismuth, zinc, cadmium, tin, iron, nickel and cobalt per 1 cc of internal volume of the luminous tube 1 are sealed up therein.
