Abstract

480,225. Discharge lamps. DESMAREST, H. G. G. May 1, 1937, No. 12462. Convention date, May 2, 1936. [Class 39 (i)] [Also in Group XX] A screen for complementing the radiation from a lamp containing mercury vapour or a rare gas such as argon, helium, or neon, comprises a transparent support carrying one or more layers of colloidal rubber covered with a finely-crystalline, luminescent metallic salt, e.g. a sulphide such as zinc sulphide. When several layers are used, they may be covered by different luminescent salts. The screen material may be applied to the lamp bulb or tube, or a surrounding bulb or and may enclose the light-source wholly-or in part. The screen layer is protected by varnish or a colourless envelope.
