取光源として脚光を浴びている。In this rare gas discharge lamp, a xenon gas discharge is generated by applying a high frequency high voltage (eg, 2500 Vp-p at 25 KHz) to the external electrodes C and D, and an emission line (147 nm) of the xenon gas causes a light emitting layer. B is excited to emit light, and the light is emitted from the opening P between the ends Ca and Da of the external electrodes C and D. In particular, since mercury is not used in this rare gas discharge lamp, the rise of the light amount after lighting is steep, and the light amount reaches almost 100% almost at the time of lighting. For this reason, it has recently been spotlighted as a document reading light source for facsimiles and the like.
