A kind of electrodeless lamp temperature control method and device

Abstract

The invention discloses a temperature control method and device for an electrodeless lamp, comprising: connecting a mercury electrodeless lamp with a high-frequency electromagnetic coil, and connecting a circuit to make the mercury electrodeless lamp work normally; inputting different frequencies and Power, respectively measure the cold end temperature of the mercury electrodeless lamp when the mercury electrodeless lamp is working normally; control the cold end temperature of the mercury electrodeless lamp to the preset threshold range, and measure the radiation intensity of the mercury electrodeless lamp within this temperature range, And the optimal cold junction temperature is calculated when the strongest radiation intensity is reached. The invention accurately measures and controls the temperature of the cold end of the mercury lamp, so that excess mercury is stored in the cold end, the temperature of the mercury electrodeless lamp is constant, the saturated vapor pressure in the bulb is stable, and the temperature of the mercury electrodeless lamp is selected at the optimum temperature, greatly improving the radiation The efficiency improves the pumping capability of the high-frequency electrodeless mercury lamp and the performance of the mercury ion microwave frequency standard.

Description

technical field [0001] The present invention relates to the technical field of electric lighting. More specifically, it relates to a temperature control method and device for an electrodeless lamp. Background technique [0002] With the development of science and technology, people put forward higher and higher requirements for the accuracy of time. The atomic frequency standard uses the frequency of the transition of the atomic energy level as a reference to measure the time, and a high-precision time standard can be obtained. The traditional atomic clocks are cesium fountain clocks, rubidium clocks and hydrogen masers. The mercury ion microwave frequency standard has high reliability, and the volume is similar to that of rubidium bells. It can achieve the high accuracy of hydrogen masers, and has significant advantages in future time-frequency applications. [0003] The physical system of mercury ion microwave frequency scale includes ion trap trapping and buffer gas co...
