態で前記光源５）を点灯すればよい。The headlamp according to the present invention is configured as described above, and when illuminating the passing beam, the threaded rod 6 is rotated to the right (clockwise), and as shown in FIG.
The lower half portion 1a of the +Q reflector 1 is moved back to a predetermined position, and at the same time the lower half portion 1b is moved forward.In this state, the light source 5) may be turned on.

パターンＰになる。At this time, the focal position of the upper part 1a of the reflector 1 is A
111", the light source 5 is located in front of this focal position Δ, and the light ray 5a incident on the upper half 1a from the light source 5 becomes downward reflected light, while the light ray below the reflector 1 The focal position of the half part 1b moves to point 8, and the light source 5 is positioned behind this focal position B.
The light ray 5b incident on the lower half portion 1b from the light source 5 also becomes downward reflected light. Therefore, when these reflected lights are projected onto a screen, a light distribution pattern P of passing beams is obtained as shown in FIG.

のりフレフタ−位置に戻せばよい。To change from this state to the traveling beam irradiation state, rotate the threaded rod 6 to the left (counterclockwise) to move the upper half 1a of the reflector 1 forward and move the lower half back to its original position. All you have to do is return it to the glue flutter position.

に示すような走行ビームの配光パターンＱになる。At this time, as shown in FIG. 4, the focal position of the upper half part 1a and the focal position of the lower half part 1b of the reflector 1 both coincide with the position of the light source 5, and this light source 5 is centered on the focal point 1: Since the light source 5 protrudes forward and backward from the bottom, the incident light from the light source 5 to the upper half 1a (13) and the lower half 1b is reflected with a slight vertical shift centering on the light ray parallel to the optical axis C. When this reflected light is projected onto a screen, it becomes a traveling beam light distribution pattern Q as shown in FIG.

極めて顕著である。(Effects of the Invention) As explained above, according to the present invention, the headlamp flaper is divided into upper and lower parts, and these parts are moved along the optical axis to shift the focus position, thereby reducing the difference between the passing beam and the traveling beam. Since the beam can be switched for irradiation, only one light source is required, and a discharge tube can be used as the light source, which increases illuminance and has an extremely significant effect.
