Title:
LIGHT-EMITTING MODULE
Document Type and Number:
WIPO Patent Application WO/2024/053465
Kind Code:
A1
Abstract:
Provided is a light-emitting module capable of controlling a region that is partially irradiated with light within a region to be irradiated. This light-emitting module comprises: a light source that is provided with a plurality of light-emitting units each including a light-emitting surface; a first lens that transmits light from the plurality of light-emitting units; a drive unit that varies the relative inclination between the optical axis of the first lens and the light-emitting surfaces; and a control unit capable of controlling light emission of each of the plurality of light-emitting units and the operation of the drive unit. The light-emitting surfaces of the light-emitting units adjacent to each other are disposed with a predetermined space therebetween when viewed from above, a region to be irradiated is irradiated with the light transmitted through the first lens, and the control unit is capable of controlling the operation of the drive unit so as to compensate for the illuminance of a region corresponding to the predetermined space within the region to be irradiated in a predetermined period.
