Abstract
Disclosed is a LED lamp compatible with electronic ballast. The positive and negative electrodes of LED array are connected with two pins of lamp via four diodes respectively, by this way, regardless of which pin is connected to the positive electrode, the lamp circuit can form a conductive path to power for the LED array, and consumers can install the lamp without distinguishing the positive and negative electrodes, improving the efficiency of LED lamp replacement.
