LIGHT SOURCE FOR HEADLIGHT AND HEADLIGHT |
摘要 |
In an LED2 having a directionality in an emission direction of emitted light, light emitted from a light emitting surface of the LED 2 is refracted by a semi-cylindrical concave lens 3 to be enlarged in the circumference direction of an optical axis of a headlight 1; thus, even when the LED2 is applied to a headlight that is constituted by optical members that are similar to optical members that are compatible with conventional light sources having no directionality, such as an incandescent lamp, a discharge lamp and the like, it can be used as a light source for headlight that is capable of illuminating the right and left directions ahead of a vehicle with a sufficient brightness. |

1. A light source for headlight to be used for a headlight provided with an optical member that irradiates light to the front side of a vehicle, comprising:
a light emitting element having a light emitting surface that is substantially planar and elongated in an optical axis direction of the headlight; and a semi-cylindrical concave lens having a focal axis in substantially the same direction as the optical axis direction of the headlight, wherein the semi-cylindrical concave lens is placed between the optical member and the light emitting element. |
