<p>In accordance with the present invention, the electrode which functions as a hot cathode during turn-on of a hot cathode type low pressure rare gas discharge lamp is heated at a temperature not lower than 800°C and not higher than 120°C. Therefore, though the lamp has an ordinary simple structure, its service life characteristics are not lowered and its brightness distribution characteristics can be improved. The lamp of this invention can be ideally used as a light emitting source for OA equipment.</p> |
