PROBLEM TO BE SOLVED: To solve a problem that a lighting surface becomes speckled by strong ly receiving a direct light from a LED lamp and the number of use is increased to generate a cost up since a radiation angle is narrow at a vehicle lighting fixture adopting a conventional LED lamp as a light source. SOLUTION: According the present invention, the LED lamp 2 is covered, from a radiation direction side, by radially combining a plurality of elliptical reflection surfaces 3 formed by a rotation ellipse surface making the LED lamp 2 as a first focus and making an axis Y approximately perpendicularly crossing an optical axis X of the LED lamp as a long axis; a paraboloidal reflection surface 4 formed by a rotated parabolic surface, in which a radiation direction is approximately parallel to the optical axis of the LED lamp, making a second focus as a focus corresponding to the second focus of the respective elliptical reflection surface 3 is provided; and a light distribution formation lens 5 is provided at a radiation direction side of he paraboloidal reflection surface 4. Thereby, an area of a light collected at a front side of the LED lamp can be enlarged with uniform brightness to solve the problem. |
