Abstract: A cathode-ray tube ultraviolet light source includes a metal housing provided with a light-transmissive window, a heatsink disposed within the metal housing, a phosphor having a first surface and an opposing second surface, wherein the second surface of the phosphor is in thermal contact with the heatsink, and an electron gun capable of developing an electron beam to impinge upon the first surface of the phosphor, whereby light emitted from the second surface of the phosphor is directed through the light-transmissive window.

Abstract: A cathode-ray ultraviolet light source comprising: an elongated glass envelope having a first end and second end, the glass envelope defining an evacuated volume; an electron gun positioned within the evacuated volume proximate to the first end and being capable of developing an electron beam; a target disposed within the evacuated volume between the first and second end of the glass envelope, the target comprising a phosphor material covered with a reflective metal film; and an electron beam focusing and deflecting mechanism disposed within the evacuated volume between the electron gun and the target to direct the electron beam towards the reflective metal film of the target.
