Abstract

PURPOSE:To obtain the maximum value of effective ultraviolet ray energy amount as well as good light source for light room film by hastening the rise-up of luminous intensity by enclosing mercury, a rare gas, together with iron, lead, and mercury iodide under a specific condition. CONSTITUTION:Mercury, a rare gas, iron, lead, and mercury iodide are enclosed in a luminous tube. And, the tubular ratio load of luminous tube is set up to approx. 45-80W/cm<2>, the amount of iron iodide formed in the luminous tube is set up to 1.5X10<-7>-5.0X10<-7>mol/cc, and the formation ratio of lead iodide to iron iodide is set up to approx. 0.1-1. Thus, the maximum value of ultraviolet rays energy can be obtained and also the rise-up of the luminous intensity can be accelerated, so that a lamp suitable for the light source of light room film can be obtained.
