ABSTRACT:
A fluorescent lamp device includes a transparent sealed container which is filled with a working gas, an electron emitting unit which extends into the container and which is operable to emit electrons that interact with the working gas to generate short-wave ultraviolet energy, and a light emitting member which is disposed in the container and which is made of an insulator material. The light emitting member has an external surface coated with a layer of fluorescent material that converts the ultraviolet energy into visible light.
