Abstract:
To provide a light-emitting device which is configured to emit fluorescence when a fluorescence source receives excitation light from an excitation light source, and which is capable of emitting fluorescence of desired intensity without requiring a process in advance.SOLUTION: A light-emitting device (10) is provided, comprising an excitation light source (11), a fluorescent layer (122), a photosensitive element (13), and an adjustment unit (14). If an intensity phase of received fluorescence is the same as that of excitation light, the adjustment unit (14) increases intensity of the excitation light per unit area at the fluorescent layer (122), and reduces the intensity if otherwise.SELECTED DRAWING: Figure 1
