Abstract

A light emitting diode (LED) tube lamp comprises: a lamp tube; a rectifying circuit, configured to rectify an input external driving signal; a filtering circuit, configured to produce a filtered signal; a driving circuit and an LED module, the driving circuit configured to receive the filtered signal in a first driving mode for driving the LED module; a mode switching circuit, configured to receive the filtered signal in a second driving mode for driving the LED module; and an auxiliary power module configured to provide 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, and the bendable circuit sheet is disposed below the printed circuit board to be electrically connected to the printed circuit board by soldering.
