<p>PROBLEM TO BE SOLVED: To perform display observing an unlit time display part, by constituting a lighting fixture from a hologram film for diffracting nearly parallel light from a light source device, provided along the surface of an outer lens, toward the radiation direction of a vehicle lighting fixture. SOLUTION: A light source device 4 is provided on a limited position, where an unlit time display part 2 is not hindered from being looked through, in a condition where an outer lens 3 is peeping in from a radiation direction Z side between the display part 2 and the outer lens 3. At unlit time of the light source device 4, such as the daytime, external light passes through the transparent outer lens 3 and a hologram film 5 to reach the display part 2 to make illumination. When the light source device 4 is lit at night, since the light is incident into the film 5 at a set angle, the light is diffracted toward the radiation direction Z to achieve a light fixture function. Such constitution makes a lighting fixture effectively and practically use a space for the vehicle lighting fixture by making the lighting fixture functions as the lighting fixture at night, and as a display part for an ornament, etc., in the daytime.</p> |
