Abstract:
Energy-saving lamps contain a gas filling of mercury vapour and argon in a gas discharge bulb. Amalgam balls are used for filling the gas discharge bulb with mercury. Novel coated balls whose operating life in the case of automatic metered introduction is increased by coating of the balls with an alloy powder and conglutination of the amalgam balls during storage and processing is prevented are proposed.
