What is the electronic ballast in lamps and lanterns
It is possible to measure the resistance of the three ballast and see whether the ballast is damaged. You can also change the glow and see if the burner is not disconnecting, and it's always on the path. So let's do substitution. Details:
Distinguish electronic ballast from good or bad Remove the glow and turn off the power and test the ballast. If the ballast is the older inductor, the inductor can test the coil if it is burned. This kind of old-style ballast is broken, usually the coil is burned, causing no voltage on both ends of the tube, causing the lamp to burn. There will be a lot of cases for electronic ballast.
Fluorescent lamp, antiseptic lamp USES electronic ballast knowledge Electronic ballast knowledge: Use of semiconductor electronic components, dc or low frequency ac voltage into a high frequency ac voltage, drive the low pressure gas discharge lamp () the sterilization lamp, halogen tungsten lamp light source such as work of the electronic control unit. The most widely used is the fluorescent lamp electronic ballast. Electronic ballast: fluorescent lamp electronic ballast, high-pressure sodium lamp electronic ballast, metal halide lamp electronic ballast. Due to adopt modern soft switch inverter technology and advanced active power factor correction technology and electronic filtering measures, has the very good electromagnetic compatibility, reduces the ballast loss itself.
Because the gas discharge lamp (e.g., fluorescent lights, neon lights, halogen lamp, metal halide lamp, etc.) is a kind of negative resistance electric light source (characteristic curve is shown in figure 1) to make its normal and stable work, need to add a current limiting device. This limited-flow device is called a ballast Development to the present, ballast in addition to the electronic ballast of high-voltage sodium lamp, metal halide lamp electronic ballasts and other normal ballast, ballasts for electron energy saving still exist, HID ballast and so on the different application of ballast If you don't understand this kind of thing, suggest you look at the sign on the ballast, and try to choose one of the more Tw (Tw130), especially the lamp It should be noted that this is the highest working temperature of the ballast coil, at which the ballast can be connected We will continue to work for ten years.
