Now mostly use traditional fluorescent electronic ballasts , customers prefer to directly replace traditional fluorescent tube LED fluorescent tubes, and therefore a way to directly compatible rectifier LED lamp market will be welcome .
Inductive ballast fluorescent silicon steel core with a coil voltage start to improve after the start and current limiting ; fluorescent electronic ballasts is the first low-frequency alternating current into direct current , converted to a high-frequency alternating current , the same after the high voltage start to run low voltage limiting . High efficiency of the latter than the former , such as a magnetic ballast itself consumes 20W to about 10W, plus the lamp is 30W, while the electronic ballast is 3-5W, plus a few lamps is 20 W .
Chengdu toward the moon Zyrjr07 type compatible LED power electronic rectifiers , which consists of a rectifier circuit and a LED driver circuit , the rectifier circuit is divided into 2-4 groups parallel rectifier circuit , rectifier filter unit on the distribution in each circuit , which consists of high-frequency diode in parallel then a high frequency filter capacitor connected in series with the low pressure differential transformer electronic filter which , using its charge-discharge characteristics , so that the pulsating DC voltage after rectification becomes a relatively stable DC voltage and, ultimately, 2-4 power LED lamp set , the packet the total number of LED lamp power to determine the size . After these improved LED fluorescent tube can be installed directly on the original electronic fluorescent lamps , greatly increasing the safety and convenience of using LED lamp , but this power can also be directly connected to 220 volts AC , no rectifier compatible fluorescent lights slot.
