PROBLEM TO BE SOLVED: To provide a vehicular light-emitting device in which even when many light sources radiate beams at different angles, and beam patterns are overlapped, the beam patterns can be matched to each other.SOLUTION: A vehicular light-emitting device includes: a light source 100 that when setting a first virtual line connecting from the center of a beam patten to the circumferential part of the beam pattern, and a second virtual line forming a preset angle to the first virtual line, forms a beam pattern so that the respective virtual lines have mutually different lengths; a diffuser 200 that receives light L of the light source 100, and diffuses the received light L so as to reduce the length difference between the first virtual line and the second virtual line, and beam guide 300 that guides a light movement route so as to collect the diffused light within a preset range.SELECTED DRAWING: Figure 3 |
