- This application is a co'ntinuation-in-part of our application Ser. No. 256,006', filed May 23', I972, now abandoned.
- the lamp of this example thus provides improved ultra-violet emission at high power from a small source which can be run from a conventional mains supply. It has the advantage that it can operate either in the horizontal or vertical position as desired.
- Such a mercury arc tube as described in Examples 1 and II containing a magnesium halide, of lower or higher wattage rating, can be designed for use as a source of visible radiation where the arc tube is contained within an outer envelope having a phosphor coating such as magnesium fiuorogermanate or yttrium vanadate to utilise the ultra-violet radiation generated and excite these phosphors to generate visible light.
- a phosphor coating such as magnesium fiuorogermanate or yttrium vanadate to utilise the ultra-violet radiation generated and excite these phosphors to generate visible light.
- a lamp as claimed in claim 1 said lamp further having a phosphor-coated outer envelope for emitting visible radiation, and in whichsaid atmosphere in said lamp further comprises trace additions of a halide of at least one of the metals in the group comprising aluminium, tin, iron, zinc, yttrium, chromium, bismuth and cadmium.
- An ultra-violet emitting mercury vapour discharge lamp comprising! an ultra-violet transmitting lamp envelope;
