Title:
LIGHTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/022124
Kind Code:
A1
Abstract:
This lighting apparatus (100) comprises: a light source (1); a first optical member (10) having M first segments (11) divided M times (where M is an integer equal to or greater than 2) in a rotation direction; and a second optical member (20) having N second segments (21) divided N times (where N is an integer equal to or greater than 2) in the rotation direction. M and N differ from each other. The first optical member (10) rotates at a first angle of rotation corresponding to the number of first segments (11), and the second optical member (20) rotates at a second angle of rotation corresponding to the number of second segments (21). One first segment (11) and one second segment (21), through which a light (L1) generated by the light source (1) passes, are selected by interlocking the rotation of the first optical member (10) and the rotation of the second optical member (20).
