Abstract
A arc discharge headlamp system is disclosed. An arc discharge headlamp system may be formed with a lamp housing including an enclosed reflector, a double ended arc discharge lamp having a two leads at offset ends, enclosed in the reflector. A first lamp support for the front end of the lamp is coupled to the lamp housing, and a first lead connection for the lamp is coupled through a high potential conductor embedded in the lamp housing. The high potential conductor embedded in the lamp housing extends subsurface to a ballast cavity formed in the lamp housing and enclosing a ballast. The ballast is potted in the cavity to protect it. A second lamp lead extends through a second lamp support to the rear of the lamp housing to be connected to the ballast. The lamp capsule, high potential leads, and ballast are all securely enclosed as a single unit with potential leakage between elements, and with the outside prevented.
