Abstract
A light-emitting device includes a light-emitting portion that emits fluorescence in response to excitation light incident on a surface of the light-emitting portion, and a reflector that defines a light-emitting region on the surface of the light-emitting portion, the fluorescence being emitted from the light-emitting region. The excitation light has a top-hat energy intensity distribution on the surface of the light-emitting portion.
Claims5
A light-emitting device comprising:
- a light-emitting portion that emits fluorescence in response to excitation light incident on a surface of the light-emitting portion;
