Abstract

A lighting device includes a lighting device body, a light source placed within the lighting device body, a lens mounted in the front opening of the lighting device body, and a hologram attached to at least one specific area on the lens. At least part of light emitted from the light source is refracted by the hologram and a holographic image recorded in the hologram 16 is reproduced. A desired pattern is recorded is recorded in the form of a holographic image in the hologram. Visual presentation and light distribution characteristics, like those a conventional lighting device having a pattern of lens steps physically formed in the lens surface, can be obtained without additional optical parts.
