IPC: F21S8/10
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To improve the visibility of a pedestrian on a road shoulder. SOLUTION: A reflecting surface segment 86 for improving the visibility of a pedestrian on a road shoulder is formed on a part, out of a reflecting surface 40, up to a predetermined distance T3 and down to a predetermined distance T2 from a horizontal line HL-HR adjacent to a part 85 where the maximum luminous intensity band 89 in a predetermined luminous intensity distribution pattern LP of a low beam and a predetermined luminous intensity distribution pattern HP of a high beam.  As a result, because part of light from a light source bulb 5 is reflected toward the road shoulder side of a traveling lane by the reflecting surface segment 86 for improving the visibility of a pedestrian on the road shoulder independent of the maximum luminous intensity band forming part 85, the visibility of a pedestrian 70 on the road shoulder of the traveling lane by the low beam is improved without adversely affecting the predetermined luminous intensity distribution pattern LP of the low beam and the predetermined luminous intensity distribution pattern HP of the high beam.
