Title:
VEHICULAR PROJECTION DEVICE, OPERATION METHOD THEREFOR, AND VEHICULAR LIGHTING FIXTURE
Document Type and Number:
Japanese Patent JP2022182192
Kind Code:
A
Abstract:
To solve the problem that intended visual effects are difficult to obtain although individual images are sequentially projected, since a road surface area allowed for projection of a certain image is limited, and also because a split number of the image is restricted.SOLUTION: A control unit 31 controls three light sources 21a-21c so as to start the projection of an image 5b to be projected secondly at a time point t4, subsequent to a time point t3 after the lapse of a period of 250/3 milliseconds from a projection start time point t1 of an image 5a to be projected first among three individual images 5a-5c. Consequently, visual effects due to projection of sequential individual images are easier to obtain compared to when starting the projection of the second individual image 5b at the time t3.SELECTED DRAWING: Figure 7
