摘要：
A discharge lamp uses resonance lines which are emitted by ions in an excitation state and has a high short wave ultraviolet ray output. The lamp is provided with a pair of electrodes, having a reciprocal spacing of equal to or smaller than 12 mm, and is of the electrode-stable type. As the major emission material, cadmium is encapsulated in a quantity permitting a partial pressure P in operation of 3.times.10.sup.3 Pa to 1.3.times.10.sup.5 Pa. The lighting operation is performed in a state in which a lamp current J.sub.L fulfills the following condition (a):0.7
