摘要 |
A head lamp in which the sub-lamp luminous intensity distribution pattern is designed to control light from a discharge bulb by a plurality of reflective surface elements constituting the reflective surface of a reflector even in such a state that the reflector has been subjected to aiming adjustment. A reflective surface element (22As1) which is positioned in the outermost side portion out of a plurality of reflective surface elements (22As) constituting the horizontal cut-line forming area (22A) of a reflector reflective surface (22) has a concave horizontal sectional shape and rays of the light reflected from the reflective surface element (22As1) are made to horizontally cross each other so as to form a luminous intensity distribution pattern (PA1). Thus, the reflector is aimed to the left and with the luminous intensity distribution pattern (PA1) as a leftover luminous intensity distribution pattern on a oblique cut line side with respect to the original luminous intensity distribution pattern when the light reflected from the left-hand end portion of the reflective surface element (22As1) is shaded by an extension (28), part of the hot zone (HZ) of a sublamp luminous intensity distribution pattern (P) is formed therewith. <IMAGE> |
