Claim of US Patent No. 10,798,794

1. A LED lighting assembly configured to retrofit a fluorescent tube, comprising:at least one LED; and
a driving circuit configured to drive the at least one LED, comprising:
a switch control module connected to the at least one LED and configured to receive and process an alternating current voltage signal from one side or two sides of the LED lighting assembly and control to drive the at least one LED based on a processed voltage signal;
a first impedance element disposed between first and second lamp pins on a first side of the LED lighting assembly;
a second impedance element disposed between third and fourth lamp pins on a second side of the LED lighting assembly;
a first rectifying circuit connected to the at least one LED and configured to convert a first alternating current power received from the first impedance element into a first direct current power provided to the at least one LED; and
a second rectifying circuit connected to the at least one LED and configured to convert a second alternating current power received from the second impedance element into a second direct current power provided to the at least one LED.
