What is the effect of temperature and voltage on UV lamps

by:Tepro     2021-06-12
As we all know, ultraviolet light is a kind of invisible light, which has a certain sterilization effect. Therefore, ultraviolet light tubes are often used for disinfection in life, especially in medicine. It is generally believed that the bactericidal effect of ultraviolet light depends on its ultraviolet radiation intensity, but professional research has shown that other environmental factors will also greatly affect the bactericidal effect of ultraviolet lamps. As we all know, ultraviolet light is a kind of invisible light, which has a certain sterilization effect. Therefore, ultraviolet light tubes are often used for disinfection in life, especially in medicine. It is generally believed that the bactericidal effect of ultraviolet light depends on its ultraviolet radiation intensity, but professional research has shown that other environmental factors will also greatly affect the bactericidal effect of ultraviolet lamps. In an indoor environment, the temperature will often change within a certain range. If the voltage is kept at a constant 220v and the radiation intensity of the ultraviolet lamp is measured by an experimental testing instrument, we can find that the temperature changes in the range of 16 to 26 degrees Celsius, and the value of the ultraviolet radiation intensity will increase from 87.6 uW/cm2 to 95.5 uW/cm2. This can be a good proof that the higher the ambient temperature, the higher the UV radiation intensity value, which directly improves the sterilization and disinfection effect of the UV lamp. If we change the experimental conditions, keep the ambient temperature constant at 20 degrees Celsius, and change the working voltage of the ultraviolet lamp. Experiments show that when the working voltage is changed from 190V to 230V, the ultraviolet radiation intensity value will increase from 59.8 uW/cm2 at 190V to 99.5 uW/cm2 at 230V. Therefore, we can conclude that under the condition of constant ambient temperature, the radiation intensity of the ultraviolet lamp will increase with the increase of the power supply voltage. Through the above analysis, we suggest that when using UV lamps, we should pay attention to changes in ambient temperature and power supply voltage. Under normal circumstances, it is best to keep the indoor temperature above 20 degrees Celsius and the voltage to be stable at 220V, so as to ensure that the UV lamp can work under better conditions and have a good sterilization effect. If you have other questions about UV lamps, please consult with UV manufacturers.
