HIGH-PRESSURE DISCHARGE LAMP

摘要

A high-pressure discharge lamp has a lead-through through the wall of the discharge space of the lamp which has a relatively high electrical resistance. In the operating condition of the lamp, heat is therefore evolved in this lead-through by the lamp current. As a result an end of the discharge vessel which generally includes the lead-through can be maintained at the desired relarively high temperature in a simple manner, which enhances the value of the luminous flux of the lamp.
