With the continuous expansion of the application field of ultraviolet germicidal lamps, in order to maximize the development of the use of ultraviolet germicidal lamps, thereby improving market competitiveness and driving the economy of enterprises, the current ultraviolet germicidal lamps are equipped with electronic ballasts, making ultraviolet sterilization The lamp has achieved more powerful functions. Generally speaking, when the power supply voltage is 220v, the ultraviolet radiation intensity of 253.7nm wavelength shall not be lower than 70μw/cm2, and the level of ultraviolet intensity directly affects the effect of disinfection. Because electronic ballasts have the advantages of energy saving and consumption reduction, rapid low-voltage start-up, and high power factor, they have become the replacement products of fluorescent lamps, but they have not been used in ultraviolet germicidal lamps. high. In addition, many products on the market are not of good quality and have low power factor. However, we can find through experiments that when the same lamp is replaced with an electronic ballast, the power consumption can be reduced by more than 25%, while the radiation intensity can be increased by more than 12%, and the life of the lamp is greatly extended. Especially for some old lamps replaced by inductive ballasts but the radiation intensity can not meet the disinfection requirements, as long as the radiation intensity is above 60μw/cm2, when the electronic ballasts are replaced, the requirements can basically be met. At the same time, the electronic ballast does not have high requirements for the power supply voltage. As long as the power supply voltage is higher than 180v, the minimum standard radiation intensity of 70μw/cm2 can be achieved. Replacing traditional magnetic ballasts with electronic ballasts, although one-time investment is relatively high, in the long run, its potential economic benefits are very considerable. Comprehensive analysis, because it can better save costs, improve utilization, and provide users with more convenient and efficient services, it is reasonable to believe that ultraviolet germicidal lamps with electronic ballasts will be an inevitable trend of development.

Ballasts common problem met in usage and guarantee for quality
Question 1: Why ballast hasn't reaction?
Solutions: To check if the ballast is powered on. The input voltage value is consistent
with ballast's rating input voltage value, or not. To check if the power cord is correctly
Question 2: Ballast is powered on, but lamp isn't lit.
Solutions: Check the product specification,and to be sure the lamp is matched with
ballast Check if the lamp is correctly connected with ballast.
Question 3: The temperature of ballast enclosure is high.
Solutions: Due to the ballast is a kind of power product, heating is a normal
phenomenon. As long as the temperature of ballast enclosure is below
70℃ , the ballast can operate normally. If the customer thinks it's
over-heating, they may adopt air cooling.
Question 4: UV lamp tube's lightness is not enough, and lamp is red.
Solutions: To check if the lamp tube is match with ballast. To check if the environment
temperature is low, that may cause the lamp
Question 5: tube to be red, due to power is not enough.
lamp tube turns to black.
Solutions: To check if the lamp tube is match with ballast. To check if lamp is powered
on-off frequently. If the lamp need to be powered on-off frequently, the
customer should choose preheat type ballast.
