Title:

LIGHT EMITTING DEVICE AND METHOD FOR MANUFACTURING LIGHT EMITTING DEVICE

Document Type and Number:

WIPO Patent Application WO/2022/270474

Kind Code:

A1

Abstract:

The present invention makes it possible to output processing light and guiding light using a simple configuration. A laser device 1A comprises: light emitting elements LD1 to LD3; a processing power supply 31 for supplying power for outputting processing light from the light emitting elements LD1 to LD3; a processing relay 40 for controlling the power supply from the processing power supply 31 to the light emitting elements LD1 to LD3; a guiding power supply 32 for supplying power for enabling output of guiding light from the light emitting elements LD1 to LD3, the guiding light being visible light of an output safe for the human body; a guiding relay 42 for controlling the power supply from the guiding power supply 32 to the light emitting elements LD1 to LD3; and a controller 10 which, when the processing light is output, controls the processing relay 40 and the guiding relay 42 so that power is supplied from the processing power supply 31 to the light emitting elements LD1 to LD3, and which, when the guiding light is output, controls the processing relay 40 and the guiding relay 42 so that power is supplied from the guiding power supply 32 to the light emitting elements.
