    Abstract: A hollow-cathode lamp comprises an anode (8) and a hollow cathode (14) opposed to an output window (3) in a bulb (4) having the output window (3); a cylindrical hood (20) having a hole (22) in its side and having an open end (20a) connected with a hollow cathode (14) and the other open end (20b) opposed to the output window (3); and an electron source (24) arranged to face the hole (22). A thermoelectron discharge takes place between the electron source (24) and the anode (8).

    Abstract: PROBLEM TO BE SOLVED: To provide a hollow cathode lamp capable of having high light output and preventing the stain on an inner surface of a bulb. SOLUTION: This hollow cathode lamp provided with a hollow negative electrode 14 facing to a light emitting window 3 and a positive electrode 8 in a bulb 4 having the light emitting window 3 includes a cylindrical hood 20 of an approximately cylindrical shape having one open end 20a connected with the hollow negative electrode 14, other open end 20b facing to the light emitting window 3, and a hole 22 formed on a peripheral side surface of the cylindrical hood 20, and an electron supply source 24 arranged in a position facing to the hole 22. Discharge using thermions is performed between the electron supply source 24 and the positive electrode 8.

    Abstract: PROBLEM TO BE SOLVED: To provide a hollow cathode lamp the inner surface of its bulb is hardly stained, capable of obtaining high output and can be manufactured easily. SOLUTION: A hollow cathode lamp has a hollow cathode 14 having a through hole 14h, a cylindrical anode 8 forming an almost cylindrical shape, an electron supply source 24 for generating discharge using a thermoelectron between the hollow cathode and the cylindrical anode 8 in the through hole 14h of the hollow cathode and a bulb 4 housing inside the hollow cathode 14, the cylindrical anode 8 and the electron supply source 24 and having a light emitting window 3, the cylindrical anode 8 is arranged so that one opening end 8d is opposed to one end 14u of the hollow cathode 14 and the other opening end 8u is opposite to the light emitting window 3 between one end 14u of the hollow cathode 14 and the light emitting window 3, and the electron supply source 24 is arranged on the other end 14d side of the hollow cathode 14.
