LIGHTING FIXTURE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To effectively use light from a light source bulb. SOLUTION: A rhomboid reflecting element 51 group has reflecting surfaces to reflect light L1 from a light source bulb F as parallel light L4 in a vertical direction and as diffused light is a horizontal direction. As a result, the light L1 from the light source bulb F is reflected by the rhomboid reflecting element 51 group, and diffusedly reflected light diffusedly reflected in a range of diffusion required for horizontal light distribution out of the reflected light is radiated through a lens 2 to the outside as it remains almost intact, while the parallelly reflected light L4 parallelly reflected vertically out of the reflected light is diffused in a range of diffusion required for vertical light distribution by a lens elements 20 of the lens 2 and radiated as diffused light L5 through the lens 2 to the outside. In this way, the light L1 from the light source bulb F is effectively used.
