Definitions
- This invention relates to discharge tubes, which term is understood to include both tubes of that type in which discharges take place between electrodes linked up with a high tension, and after ionization cause the filling to light, as well as tubes in which a so-called basic gas is ionized by means of a hot cathode, metallic vapors thus being induced to radiate.
- the ignition potential may be considerably reduced as compared with nickel carbonyl.
- the life of the luminous tube is, however, adversely affected thereby.
- the filling does not require to contain one of the stated metal carbonyls alone.
- the carbonyls above referred to may also be employed in mixture. It is also possible to employ for part of the filling other gases than those hitherto in use. Upon lighting the white color of the light is not changed so long as the partial pressure is maintained which is peculiar to each carbonyl. The presence of mercury does also not interfere with the pure white color of the light.
- a discharge tube having a filling which consists of nickel carbonyl and rare gases.
- a discharge tube having a filling which consists of nickel carbonyl and mercury.
- a discharge tube of the type that ionizes a basic. gas by a heated cathode comprising, in combination, an evacuated glass bulb, at least two electrodes sealed into the said bulb and separated by a gap, and a-permanent filling of at least one metal carbonyl vapor.
- a discharge tube of the type that ionizes a basic gas by a heated cathode comprising, in combination, an evacuated glass bulb, and a permanent filling of nickel carbonyl at a pressure of approximately 1.5 millimeters of mercury.
