The LED tube can be used directly behind the fluorescent lamp rectifier, without the need to modify the original fluorescent lamp circuit. LED tubes are divided into LED tubes that look like fluorescent tubes and are becoming more and more popular among customers. Such LED tubes are similar in appearance and length to conventional fluorescent tubes. They are usually the same as the physical dimensions of fluorescent tubes described in the standard NEMA C78.81. According to the way they are used, they can be divided into three categories, type A, Type B and typeC LED tubes; after corresponding confirmation or modification of the original fluorescent lamps, such as removing the original fluorescent lamp rectifiers, rewiring the original lamp holders, etc., so as to replace the original fluorescent lamps . Type B tube-high-voltage tube, the LED drive circuit is built into the LED tube, integrated LED tube, the input line of the LED driver is connected to the pin inside the tube, so the pin of the tube can pass The lamp socket of the lamp is directly connected to the mains. You can only apply for R/C type B lamps. The product category is OOLV2, which can cooperate with IFAR certification and meet the standards. Type C lamp-usually a low-voltage lamp, which needs to be used with an external LED driver. Only R/C type C lamps can be applied for. The product category is OOLV2. It can cooperate with IFAR certification and meet the standard UL1598C. After corresponding confirmation or modification of the original fluorescent lamp, such as removing the original fluorescent lamp rectifier, replace the original There are lamp holders and LED drive wiring on the lamp, so as to replace the fluorescent tube of the original fluorescent lamp.
