Vehicular lamp having improved uniformity of light emission

摘要

In a lamp for an automobile in which the front opening edge of a lamp housing is covered with front lenses or outer lenses to form lamp chambers for accommodating therein bulbs serving as light sources. An inner lens is provided inside the front lenses or the outer lenses, and a diffusion reflection layer fabricated by roughening processing or the like is formed particularly on a part of an outer peripheral surface of a flange portion of the inner lens or the entire outer peripheral surface thereof. Light emitted by the bulb is irregularly reflected by the diffusion/reflection layer so as to prevent a portion higher in brightness than other portion from appearing in the light emitting planes of the front lenses or the outer lenses.
