PROBLEM TO BE SOLVED: To provide a lamp unit for an automobile, capable of emitting various colors of light by mixing a plurality of colors of light, having a simple and low-cost structure, and capable of uniformly mixing light from respective light sources without causing separation. SOLUTION: This lamp unit 1 for an automobile enables various colors of light unparalleled as an automobile lamp to be realized by adjusting the light-quantity mixing ratio of light from a plurality of light sources 3R, 3G, 3B. The plurality of collectively disposed light sources 3R, 3G, 3B are covered by a shading part 5 around a fixed axis 0, the light from the light sources 3R, 3G, 3B is thereby guided to a translucent light mixing/radiating part 4 neighboring in the direction of the axis 0 and mixed there, and the mixed light is radiated from a light radiating surface 15 formed on an outer circumferential surface of the light mixing/radiating part 4, Because the light sources 3R, 3G, 3B are covered with the shading part 5 in the radiating directions of light, colors are prevented from being seen separated and various colors of light can be uniformly mixed. |
