Abstract

PURPOSE: To obtain this lamp that the quantity of ultraviolet rays with not more 2500Å wavelength radiated is large and is suitable for the printing, transcription, etc. of a LSI, etc., by perfectly preventing the existence of halogen gas in a bulb, and by enclosing a specified quantity of zinc and rare gases with specified pressure.
CONSTITUTION: The existence of halogen gas 1 completely obviated in a bulb 1, to which a pair of electrodes 8, 9 are mounted, and 10-4W1mg zinc per 1cc inner volume of the bulb and rare gases with 1W10 atmospheric pressure are enclosed. For example, the anode 8 and the cathode 9 are installed into an approximate Rugby ball-like quartz bulb 1, and 0.1mg/cc zinc and xenon gas with 5 atmospheric pressure at 25°C are enclosed in the bulb 1, thus preparing this short arc type discharge lamp of 25V operating voltage and 500W consuming power. Consequently, this discharge lamp can be obtained which the quantity of ultraviolet rays with 2140Å wavelength radiated is large and the accuracy of finishing can be improved and working hours can be shortened when using this lamp for the printing, transcription, etc. of a LSI, a super-LSI, etc.
