PROBLEM TO BE SOLVED: To provide a vehicular lighting fixture capable of satisfying desired light distribution standards with two light emitting elements.SOLUTION: A vehicular lighting fixture 1 is constituted which includes a pair of left and right LEDs 5L, 5r, a center reflector 6A reflecting light from the respective LEDs 5L, 5R, and side reflectors 6BL, 6CL and 6BR, 6CR arranged on both left and right sides of the center reflector. A reflecting surface of the center reflector 6A is a parabolic cylinder surface including, as its focal line L, a horizontal line passing the respective centers of the LEDs 5L, 5R, reflecting surfaces of the side reflectors 6BL, 6CL and 6BR, 6CR are curved surfaces obtained by sweeping a parabola, having its focus at an end point P1 or P2 of a light emission surface of an LED on a side farther from the side reflector, in a lateral direction, and the LEDs 5L, 5R are arranged where light emitted from the LED 5L or 5R on a side closer to each side reflector, reflected by the reflecting surface of the side reflector, and projected on a screen has an intensity at 6D which is 1/2 or less as large as an intensity at 2.5D.SELECTED DRAWING: Figure 6 |
