ABSTRACT:
A reflector 11 to which a discharge bulb 16 is attached is made of a conductive material, and a casing (turn-on circuit casing 30) made of a conductor is attached to a rear-side opening portion of a lamp body enclosing the reflector so that the opening is closed. A grounded shielding tube 21 is provided to enclose the discharge bulb 16, and a grounded extension reflector 3B is disposed at the opening of the reflector 11. At least the reflector 11 and the casing 30 are collectively grounded so that it becomes possible to suppress the electromagnetic waves radiated from the discharge bulb 16 to its circumference.
