Abstract
Provided herein is a light-emitting apparatus which is capable of causing the light emitted at the entire face of a fluorescent material to be exteriorly emitted with no interference and with enhanced light emission efficiency, thereby attaining an exteriorly radiated high brightness light. A cathode electrodeis mounted on a periphery of a transmission member, the anode electrodeis also mounted on a domain opposite to a light transmission member, and the surfaceof the fluorescent materialto be mounted on a top layer of the anode electrodeis formed with a concave face. In accordance therewith, even when the cathode electrodeis offset mounted on a periphery of the light transmission memberit can be caused to precisely face the surfaceof the fluorescent materialand the excitation light from the entire face of the surfaceof the fluorescent materialcan made incident onto the light transmission memberwithout interference from the cathode electrodeor the like.
