The present invention provides an LED lighting module with radiating and automatic power-off functions. The module includes a power supply element, an LED element and radiating member as well as a circuit linking them. The circuit linking the power supply element, LED element and radiating member is a serial loop, so that the power supply element, LED element and radiating member are combined into a single loop circuit. The LED elements will be automatically turned off if the radiating member is burnt to prevent the overheating problem of LED elements and to prolong the service life with improved applicability.
