<p>In the conventional lighting equipment for vehicle using LED lamp, as the LED lamp irradiation angle is narrow, an optical irregularity making the luminescent surface spotted is generated, resulting in a feeling of wrongness of the viewer. Means to Solve the Problem. A LED lighting equipment 1 for vehicle of the present invention, comprising at least one light emitting unit 3 wherein an LED lamp 2 is disposed approximately at the focus of one hyperboloid, a reflection surface of hyperboloid 4 defined by the other hyperboloid comprising a transmission portion 4a disposed in an appropriate range near the optical axis is arranged in the LED lamp 2 optical axial direction, and a refection surface of paraboloid of revolution 5 having the approximate focus at the focus of said the other hyperboloid focus is arranged at the side of said LED lamp 2, allows to enlarge the irradiation angle at the reflection surface of hyperboloid 4, and to emit light in a larger area. <IMAGE></p> |
