Abstract:
A headlight device comprising:a high voltage electric-discharge lamp having a shape elongated in a direction from front to back;a reflector having a curved surface for reflecting light emitted from the high voltage electric-discharge lamp, the reflector being disposed to include the high voltage electric-discharge lamp within a space in front of the curved surface;a control circuit for energizing the high voltage electric-discharge lamp; anda shade covering a front side of the high voltage electric-discharge lamp for intercepting light emitted directly forward from the high voltage electric-discharge lamp and at least one support plate connected to the shade for mounting the shade on the reflector, wherein at least a part of said shade and the support plate are made of a metallic material that is not electrically connected to a high voltage side of the electric-discharge lamp, and said part of said shade is grounded through the support plate to intercept electromagnetic noise emitted forward from the high voltage electric-discharge lamp.
