Definitions
- This invention relates to electric discharge tubes and more particularly to electric discharge tubes having a positive column light for lighting purposes.
- Discharge tubes of this kind have the disadvanta e that if for any reason the temperature 0 the tube becomes too' low (for example by reason of a low temperature of the surrounding open air), the vapour pressure of the mercury may acquire such a low value that the mercury practically no longer takes part in the discharge and theblue mercury light changes to the red neon light.
- a gaseous fill-- ing is introduced into a discharge tube with positive column light, which gaseous filling comprises arggn and mercury vapor.
- the gaseous filling may consist of ar on, kr ton, xenon and mercury vapor.
- referabl y a gaseous filling of argon and mercury, the argon pressure of whlch is above 4 millimetres of mercury will be used.
- Discharge tubes according to the invention are capable of still producing mercury li ht at temperatures at which a discharge tu e having positwo light and filled with neon and mercury alread produces neon light. This is a very remar able phenomenon, as the exciting potential of argon is lower than that of neon.
- an argon mercury ciency of discharge tubes according to the invention will likewise be greater than that. of discharge tubes having a positive light and a gaseous filling of neon and mercury.
- A' discharge tube for positive column light the gaseous filling of which comprises argon and mercury vapor.
- a discharge tube for positive column light the gaseous filling of which consists o argon, krypton, xenonand mercury vapor.
- a discharge tube for ositive column light, the gaseous filling 0 which consists o argon having a pressure above 4 millimetres of mercury pressure and of mercury vapor.
