Led tube lamp with multi-driving mode

A light-emitting diode (LED) tube lamp, comprising:

• a lamp tube, configured to receive an external driving signal;
• a rectifying circuit, configured to rectify the external driving signal to produce a rectified signal;
• a filtering circuit, configured to filter the rectified signal to produce a filtered signal;
• an LED lighting module, comprising a driving circuit and an LED module, the driving circuit configured to receive the filtered signal in a first driving mode to produce a first driving signal for driving the LED module to emit light;
• a mode switching circuit, configured to receive the filtered signal as a second driving signal in a second driving mode for driving the LED module to emit light, wherein the first driving mode and the second driving mode are determined according to the external driving signal;
• and
• an auxiliary power module coupled to the filtering circuit, and configured such that when the first driving signal or the second driving signal is unable to drive the LED module to emit light, the auxiliary power module provides auxiliary power for the LED module to emit light,
• wherein the mode switching circuit is on a printed circuit board and is electrically connected to the LED module on a bendable circuit sheet in the LED tube lamp, wherein the bendable circuit sheet is disposed below the printed circuit board to be electrically connected to the printed circuit board by soldering.
