DC operated alkali metal vapor arc discharge lamp |
| abstract |
(57) [Summary] [Purpose] In an arc discharge lamp of alkali metal vapor that operates at direct current and uses an amalgam of mercury and an alkali metal such as sodium, during operation of the lamp, mercury and alkali in the arc discharge Prevents electrophoretic separation of metals. [Structure] The ratio of the pressure of the alkali metal vapor at the cathode and the anode is set to 5 or less, and the temperature at the cathode end is 50 ° from the temperature at the anode end. Make it higher. The lamp is designed so that the value of the electrophoretic drive parameter (CDP) is smaller than 150. C DP is defined as the product of the arc current in amps and the arc gap length in centimeters divided by the square of the inner diameter of the arc tube in centimeters. |
