Title:
LIGHT-EMITTING MODULE
Document Type and Number:
WIPO Patent Application WO/2024/038804
Kind Code:
A1
Abstract:
Provided is a light-emitting module capable of radiating light that is adjusted to a prescribed color. The light-emitting module comprises: a light source that includes a plurality of light emitting units which include a first light emitting unit that emits light having a first chromaticity and a second light emitting unit that emits light having a second chromaticity different from the first chromaticity, and each of which has a light emitting surface; a lens that transmits the light from the light source; a drive unit that can change the relative positions of the light source and the lens in a direction crossing the optical axis of the lens and/or the relative inclinations of the light emitting surfaces and the optical axis of the lens; and a control unit that is capable of controlling light emission of each of the plurality of light emitting units and operation of the drive unit, wherein the control unit performs control so as to cause the plurality of light emitting units to emit light during the operation for changing the relative positions and/or the relative inclinations by the drive unit, and so as to overlap, in an irradiated region, the positions of at least a portion of the light from the first light emitting unit that has passed through the lens prior to the operation and at least a portion of the light from the second light emitting unit that has passed through the lens after the operation.
