Electrodeless lamp temperature control method and device

Abstract

The invention discloses an electrodeless lamp temperature control method and device. The method comprises the steps that mercury electrodeless lamps are connected with a high-frequency electromagneticcoil, and a circuit is connected to make the mercury electrodeless lamps work normally; different frequencies and powers are input to the mercury electrodeless lamps, and the cold-end temperatures corresponding to the mercury electrodeless lamps are measured respectively when the mercury electrodeless lamps work normally; the cold-end temperatures of the mercury electrodeless lamps are controlledwithin a preset threshold value range, the radiation intensity of the mercury electrodeless lamps within the temperature range is measured, and the optimal cold-end temperature is calculated when thehighest radiation intensity is reached. According to the method and device, by precisely measuring and controlling the cold-end temperatures of the mercury lamps, redundant mercury is stored at the cold ends, the temperature of the mercury electrodeless lamps is constant, the saturated vapor pressure in bulbs is stable, the temperature of the mercury electrodeless lamps is selected to the optimaltemperature, the radiation efficiency is greatly improved, and the pumping capability of the high-frequency electrodeless mercury lamps and the mercury ion microwave frequency marker performance areimproved.
