Provided herein is a light-emitting apparatus capable of achieving both improved durability and higher brightness with an inexpensive and simple construction. A heat resistant glass substrateis mounted in a vacuum chamber, and while an anode electrode(and a light emitter) is mounted on the glass substrate, the glass substrateis separated from a glass substrate. This precisely protects the vacuum chamberfrom thermal damage due to light emission upon excitation, even when the current density between the cathode electrodeand the anode electrodeis controlled at a high level to cause the light emitterto emit light at high brightness. Accordingly, this eliminates the need to make the entire vacuum chamberexcessively heat-resistant, permitting construction from an inexpensive material such as soda-lime glass; consequently both improvements in the durability of the light-emitting apparatusand enhancement in brightness thereof can be accomplished with an inexpensive and easy construction.

Light-emitting apparatus having a heat-resistant glass substrate separated through a vacuum layer from a glass substrate used as the light projection plane

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.
