摘要: An all-metal electron emissive structure for low-pressure lamps is disclosed. The consisting of one or more metal operable to emit electrons in response a thermal excitation, wherein an active region the under steady state operating conditions has temperature greater than about 1500 degree K, and cathode fall voltage discharge medium less 100 volts. A lamp including envelope, electrode structure, medium, also
