UV sterilization lampuv bulb,uv light,uv lamp As a simple and easy-to-use disinfection equipment, it is widely used in health and epidemic prevention, biopharmaceuticals, food research and other departments. Through research, it has been found that the intensity of ultraviolet light sources is not only related to ultraviolet lamps, but alsouv bulb,uv light,uv lamp The quality of the tube itself is related not only to temperature and humidity, but also to the ballast.
According to the UV disinfection regulations issued by the Ministry of Health, when the power supply voltage is 220V, the UV radiation intensity of 253.7nm wavelength shall not be less than 70 μ W/cm2, and the level of UV intensity directly affects the disinfection effect.electronic ballastIt has the advantages of energy saving and consumption reduction, rapid low-voltage start-up, high power factor, etc., and has become a replacement product for fluorescent lamps. However, it is not suitable for ultraviolet sterilization lampsuv bulb,uv light,uv lamp However, it has not been widely applied, mainly due to high costs and a relatively high failure rate. In addition, many commercially available products have poor quality and low power factor. But we found through experiments that replacing the same lamp tubeelectronic ballastAt this time, power consumption can be reduced by more than 25%, while radiation intensity can be increased by more than 12%, and the service life of the lamp tube can be greatly extended. Especially for some old lamps that use inductive ballasts but do not meet the disinfection requirements for radiation intensity and need to be replaced, as long as the radiation intensity is above 60 μ W/cm2, they can basically meet the usage requirements when using electronic ballasts. Electronic ballasts do not have high requirements for power supply voltage. As long as the power supply voltage is higher than 180V, the minimum standard radiation intensity of 70 μ W/cm2 can be achieved. Replacing traditional inductive ballasts with electronic ballasts, although the one-time investment is relatively high (the electronic ballast we used in our experiment was around 30 yuan), has significant potential economic benefits in the long run. If a hospital has 100 light tubes and uses them for 2 hours a day, then after switching to electronic ballasts:
Based on a 25% energy saving and a lamp lifespan of 1000 hours, it can save nearly 350 yuan in electricity bills annually.
Based on a cost of 85 yuan per lamp tube and a lifespan extension of at least 100 hours, a savings of 900 yuan can be achieved. However, these 100 lamp tubes can save over 1200 yuan during their service life. And 100 electronic ballasts are worth only 3000 yuan. If the value of the inductive ballast is further removed, the total investment will be smaller and the investment can be quickly recovered.
Using electronic ballasts can significantly increase radiation intensity and prolong lifespan while reducing power consumption.
