Abstract
An arrangement for emitting light includes a hermetically sealed casing with a window, a layer of a fluorescent substance arranged within the casing covering at least a major part of the window, an electron emitting cathode arranged within the casing, and an anode. The casing is filled with a gas suitable for electron avalanche amplification. In operation, the cathode and anode are held at an electric potential such that said emitted electrons are accelerated and avalanche amplified in the gas. The layer of the fluorescent substance is arranged to emit light through the window in response to avalanche amplified electron bombardment and/or ultraviolet light emitted from the gas.
