Electric discharge tube, method of manufacturing the tube, stroboscopic device using the tube and camera |
摘要 |
An electric discharge tube withstands a large electric input, and has a small size. This discharge tube provides a small photographic strobe device and a small photographic camera. The discharge tube includes a glass bulb having a wall thickness ranging from 0.2 to 0.6 mm and filled with rare gas, a pair of main electrodes provided at both ends of the glass bulb, respectively, a trigger electrode formed on the outer surface of the glass bulb, and a film of silicon dioxide having a thickness ranging from 0.05 to 0.11 mum formed inside of the glass bulb. An electric power not larger than 0.90 Ws/mm<3 >with respect to the inner volume of the glass bulb is applied between the main electrodes.
