Title:
LIGHT EMISSION MODULE
Document Type and Number:
WIPO Patent Application WO/2023/145248
Kind Code:
A1
Abstract:
A light emission module (100) includes: a substrate (110); a plurality of light sources (120) that are fixed on the substrate (110) and the outputs of which can be individually controlled; light blocking members that are disposed among the plurality of light sources (120); a first lens (131) that is disposed above the plurality of light sources (120) and on which light generated by each of the light sources (120) is incident; and a drive unit (140) that can rotate the substrate (110). The plurality of light sources (120) include a first light source and a second light source. An angle formed by the optical axis of first light generated by the first light source and emitted from the first lens (131) and the rotation axis (D3) of the substrate (110) is different from an angle formed by the optical axis of second light generated by the second light source and emitted from the first lens (131) and the rotation axis (D3). The second light can be radiated in a first circular orbit centered on the rotation axis (D3).
