Document Type and Number:
Japanese Patent JP6934393
Kind Code:
B2
Abstract:
To achieve improvement on visibility when a plurality of light emission parts sequentially emit light with time difference.SOLUTION: At least three light emission parts that emit light are arranged in alignment. The light emission parts sequentially emit light with time difference in the alignment direction of the light emission parts. Two light emission parts adjacent to each other are provided as an adjacent luminous body. Between two light emission parts in at least one adjacent luminous body, a shading part that blocks light emitted from one light emission part from advancing toward the other light emission part side is provided. A difference in emission start time of two light emission parts in an adjacent luminous body where a shading part is not provided between the two light emission parts is regarded as a first time difference. A difference in emission start time of two light emission parts in an adjacent luminous body where a shading part is provided between the two light emission parts is regarded as a second time difference. The second time difference is made less than the first time difference.SELECTED DRAWING: Figure 1
