The present invention addresses the problem that the road surface area allowed for projecting an image is limited, there is a restriction on the number of parts into which the image can be divided, and it is hard to achieve an intended visual effect even if individual images are sequentially projected. A control unit (31) controls three light sources (21a to 21c) so that, among three individual images (5a to 5c), projection of an image (5b) to be projected second is started at a time point (t4) later than a time point (t3) at which a period of 250/3 milliseconds has elapsed from a projection start time point (t1) for an image (5a) to be projected first. Consequently, the visual effect of sequential projection of individual images is more easily achieved than when the projection of the second individual image (5b) is started at the time (t3).

ARRANGEMENT OF LIGHT SHAPING OPTICAL ELEMENTS FOR AUTOMOTIVE SIGNAL LIGHTING

A vehicle includes individual light sources that are separated in space from neighboring light sources. Collimators can collimate light emitted from the light sources, and a first diffusing surface is configured to receive the collimated light and to diffuse the collimated light in a first direction transverse to a first propagation direction of the collimated light. A second diffusing surface is configured to receive the light diffused by the first diffusing surface and to diffuse the received light in a second direction transverse to a second propagation direction of the collimated light.
