Abstract
In a hollow cathode lamp comprising, in a bulb having a light exit port, a hollow cathode and an anode opposed to the light exit port, which comprises a tubular hood having a tubular shape, having one open end connected to the hollow cathode, having another open end opposed to the light exit port, and having an opening formed in a peripheral side face thereof, and an electron supply disposed at a position to front on the opening, discharge making use of thermoelectrons is implemented between the electron supply and the anode.
Claims6
A hollow cathode lamp comprising, in a bulb having a light exit port, a hollow cathode and an anode opposed to said light exit port, said hollow cathode lamp comprising:
- a tubular hood having a tubular shape, having one open end connected to said hollow cathode, having another open end opposed to said light exit port, and having an opening formed in a peripheral side face thereof;
- and
- an electron supply disposed at a position to front on said opening,
- wherein discharge making use of thermoelectrons is implemented between said electron supply and said anode.
A hollow cathode lamp comprising, in a bulb having a light exit port, a hollow cathode and an anode opposed to said light exit port, said hollow cathode lamp comprising:
- a tubular hood having a tubular shape, having one open end connected to said hollow cathode, having another open end opposed to said light exit port, and having a slit formed in a peripheral side face thereof;
- and
- an electron supply disposed at a position to front on said slit,
- wherein discharge making use of thermoelectrons is implemented between said electron supply and said anode.
