Abstract
An automotive headlight with a high-pressure gas discharge lamp arranged inside a reflector contains an electronic ballast in a housing for operation of the high-pressure gas discharge lamp. The housing dissipates heat generated by the electronic unit in particular and possibly also by the high-pressure gas discharge lamp and provides an electromagnetic shield against any resulting electronic radiation. Cooling ribs may be provided on the housing to aid in heat dissipation.
