ABSTRACT:
An automobile headlamp with a reflecting surface comprising a plurality of light distribution steps arranged on the surface. Out of the plurality of light distribution steps 12a constituting the reflecting surface 12, the light distribution steps 12aA, 12aB positioned at upper left and upper right corners with respect to an optical axis Ax of a reflector 10 are formed so that luminous fluxes of reflected light from upper areas A1, B1 thereof and luminous fluxes of reflected light from lower areas A2, B2 thereof can emit downward with broken lines interposed therebetween. As a result of this construction, even if headlamp parts forming accuracy requirements are not adequately met, undesired upward emitting of the luminous fluxes of reflected light from the upper areas A1, B1 is prevented. Further, by forming the upper areas A1, B1 and the lower areas A2, B2 of vertically long single light distribution steps 12aA, 12aB, respectively, not only division of the reflecting surface 12 into small segments can be minimized, but also steps between the upper areas A1, B1 and the lower areas A2, B2 are eliminated, so that the likelihood that upward scattered light will be generated is excluded.
