ABSTRACT:
A lens for a light distribution has an incident surface and an exit surface, where the exit surface is an aspheric surface so that an aberration of the outer periphery in the horizontal direction can be larger than an aberration of the outer periphery in the vertical direction of the exit surface. Among light distributions formed by an outgoing light emitted from the exit surface, a light distribution in the horizontal direction blurs on the peripheral portion but a light distribution in the vertical direction does not blur on the peripheral portion.
