Description

Technical Field

[0001] The utility model relates to the technical field of deuterium lamps, in particular to a deuterium lamp. Background Art

[0002] A deuterium lamp, also known as a gas tritium light source, is a device that uses the β decay characteristics of tritium gas to emit light. It consists of a borosilicate glass shell or tube coated with zinc sulfide phosphor inside. When tritium gas decays, the released electrons hit the phosphor and stimulate it to emit light.
