Abstract
An LED tube lamp includes a lamp tube having two pins to receive an external driving signal; a rectifying circuit coupled to the two pins to rectify the external driving signal; a filtering circuit coupled to the rectifying circuit to filter rectified signal; and an LED lighting module coupled to the filtering circuit to receive the filtered signal to emit light. The LED lighting module further has a driving circuit and an LED module, the driving circuit includes a controller and a conversion circuit coupled to the filtering circuit to receive and convert filtered signal into driving signal to drive the LED module. The LED tub lamp further includes an over voltage protection circuit coupled to the filtering circuit for detecting the filtered signal, the over voltage protection circuit clamps the filtered signal when determining the filtered signal is higher than a defined over voltage protection value.
