摘要：<p>PURPOSE:To prevent an irregularity in brightness on a display portion by laminating a light guiding plate, a hologram, a low-refraction factor layer, and an irregular reflection layer into a luminescence section, and combining the luminescence section with a thin rectangular body structure and two light sources in a high-mount stop lamp. CONSTITUTION:This lighting fixture for a vehicle is provided with two light sources 3, 4, and the light emitted from the light sources 3, 4 is fed to a thin luminescence section 5 within the prescribed range near to the center of a vehicle. The thin luminescence section 5 is constituted of a light guiding plate 10, a hologram 11, a low-refraction factor layer 12, and an irregular reflection layer 13. The hologram 11 is constituted of the right and left holograms 11a, 11b. The holograms 11a, 11b reflectively diffract the light entering under the conditions of the prescribed wavelength and the prescribed incidence angle among the light emitted from the light source 3 and fed via the light guiding plate 10 so that the light proceeds with total reflection in the light guiding plate 10 and proceeds to the light sources 4, 3. The undiffracted light and the light not satisfying the conditions goes out to the rear of the vehicle.</p>
