Abstract：The purpose of this study is to enhance the performance of low-pressure mercury lamps(LPMs)under low-temperature conditions and develop a quartz insulation sleeve that can be filled with gas.It's found that the optimal mercury vapor working temperature for low-pressure mercury lamps is 125.9℃,at which the 254 nm UV irradiance reaches its peak.In the temperature range from-20℃to 20℃,different gases filled in the sleeve can adjust the lamp surface temperature to optimize the mercury vapor temperature to the optimal working temperature.The results show that Argon(Ar)at-20℃and-10℃is beneficial for insulation and improving irradiance.At 0℃,10℃and 20℃,filling with air or nitrogen helps maintain the efficient and stable operation of the lamp.
