Document Type and Number:
WIPO Patent Application WO/2021/079758
Kind Code:
A1
Abstract:
The present invention provides a light-emitting device for emitting fluorescence upon receipt of excitation light from an excitation light source at a fluorescent source, such that the light-emitting device emits fluorescence at a desired intensity irrespective of pretreatment. The light-emitting device has an excitation light source, a fluorescent layer, a light-receiving element, and an adjustment device. The adjustment device increases the intensity of the excitation light per unit area on the fluorescent layer if the phase of the intensity of the received fluorescence and the phase of the intensity of the excitation light are the same, or decreases the intensity if otherwise.
