Document Type and Number:
WIPO Patent Application WO/2018/225254
Kind Code:
A1
Abstract:
The present invention makes it possible to be quickly in a stable light emitting state without deteriorating cooling efficiency even at a time when the ambient temperature is low. The present invention has: a plurality of kinds of solid-state light source elements (102-107) that respectively generate light having different colors; a circulation path (100), wherein the plurality of kinds of solid-state light source elements (102-107) are attached, and the solid-state light source elements (102-107) and a heating medium circulating in the circulation path are thermally coupled to each other; a temperature detection unit (101) that detects the temperature of the heating medium; and a control unit (115), which circulates the heating medium in the circulation path (100) when the control unit receives a start command, and which sequentially starts the plurality of kinds of solid-state light source elements (102-107) in accordance with a temperature increase detected by the temperature detection unit (101).
