摘要： A high pressure sodium lamp is provided with an outer envelope (1,2) containing a rare gas at a pressure of approximately one atmosphere. A metallic reflective layer (5) is disposed on a portion (2) of the outer envelope for defining a reflector. The lamp comprises a discharge device (10) mounted within the outer envelope and provided with a pair of conductors (14,15). The pair of conductors (14,15) are configurated to have a breakdown voltage between them greater than a certain value and to maintain the breakdown voltage between the conductors and the metallic reflector greater than the certain value.
