CATHODE WITH INTEGRATED GETTER AND LOW WORK FUNCTION FOR COLD CATHODE METHODS FOR MANUFACTURING SUCH A CATHODE

Document Type and Number:

WIPO Patent Application WO2005048293

Kind Code:

A3

Abstract:

There are disclosed several embodiments of a cathode (11; 20; 30) for cold cathode lamps having the surface at least partially coated with a layer of a getter material (15; 26; 31), which allows to achieve a reduction of the value of the work function of the cathode (11,20,30) and therefore a reduction of the power consumption of the lamp.
