Abstract

An LED lamp, an integrated circuit and a power supply module thereof are provided. The LED lamp includes and LED module, two end caps, two rectifying circuits, a pi filter circuit, a conversion circuit, a control circuit, a mode switching circuit, and a mode determining circuit. Each end cap has two conductive pins for receiving an external power, and at least one pin is set to a floating state. The control circuit can temporarily cause a current path to be conducted according to a signal received from a first pin, detect whether the LED lamp is properly connected according to signal received from a second pin, and output a control signal through a third pin after the LED lamp is determined to be properly connected such that the conversion circuit generates the driving signal with a steady current which makes the LED module emitting steady light.
