ABSTRACT:
A wide-ranged hot zone light distribution is obtained by using one hot zone light distribution lens in a simple construction. The hot zone light distribution lens has a first light reflection surface forming roughly a vertical surface and a second light reflection surface adjacent to the first reflection surface forming a line as a border at the top edge of the reflection surface in a projection direction. A hot zone light distribution includes at least a first range formed by a direct light projected from an optical fiber without being reflected on the first and second reflection surfaces, a second range formed by a reflected light projected after being reflected on the first reflection surface, and a third range formed by a reflected light projected after being reflected on the second reflection surface. The first and the second ranges are extended toward right and left directions from a horizontal center in the light distribution. The first range has a top end increasing its height toward an outside.
