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 electrode10is mounted on a periphery of a transmission member30, the anode electrode15is also mounted on a domain opposite to a light transmission member30, and the surface16aof the fluorescent material16to be mounted on a top layer of the anode electrode15is formed with a concave face. In accordance therewith, even when the cathode electrode10is offset mounted on a periphery of the light transmission member30it can be caused to precisely face the surface16aof the fluorescent material16and the excitation light from the entire face of the surface16aof the fluorescent material16can made incident onto the light transmission member30without interference from the cathode electrode10or the like.
