Abstract: A discharge bulb is equipped with an arc tube main unit including in a ceramic tube a discharge light emitting chamber where electrodes are provided face to face and a luminescent material is filled, with substantially the lower half of the outer peripheral surface of the ceramic tube covered by a light shielding ember. Light to be emitted from the ceramic tube is also emitted from the upper part and directed to the efficient reflecting surface of the reflector thus raising the luminance intensity of the headlamp. In the process of light distribution design of the reflector, the size of the rectangular light source image to be projected (stuck) along the cutoff line is made slimmer (narrower). By perform light distribution design (of the effective reflecting surface) so as to allow the maximum luminance part to approach the cutoff line, the hot zone gets closer to the cutoff line position with improved long distance visibility.

Abstract: An arc tube for a discharge bulb is provided for use in a vehicular lighting system. The arc tube includes a closed glass bulb that is pinch-sealed at opposite ends. Inner ends of a first electrode and a second electrode extend into the closed glass bulbs from the ends of the closed glass bulb. The atmosphere inside the closed glass bulb includes a starting rare gas, a primary light-emitting metal halide, and optionally, a buffer metal halide. The distance between the inner ends of the electrodes is between about 0.3 and 1.8, and the inner diameter of the closed glass bulb at a middle portion is between about 1.5 mm and 2.7 mm. Accordingly, a stable discharge is produced using between 15 W and 30 W of power.

Abstract: In a discharge lamp device, the arc tube body is configured by welding and integrating shroud glass with an arc tube so as to enclose a discharging portion, and a rearward elongating portion of the arc tube that elongates in the rear of the shroud glass is inserted and held into an opening of an insulating plug which is made of synthetic resin. A UV blocking film is formed on the outer surface of the rearward elongating portion of the arc tube. UV components of leakage light from the rearward elongating portion are cut off, and the amount of ultraviolet rays to which the resin layer in the opening is exposed is reduced. The UV blocking film is in the opening, and hence cannot be seen through a front lens.
