A self-powered luminant banner is provided, including at least a brace, at least a blade, and a controller. The blade is attached to the brace with at least one side. The blade further includes at least an embedded piezoelectric transducer and at least a luminous element attached to the blade. The piezoelectric transducer embedded in the blade has related circuitry for electrically connecting to the controller so that the controller can power the luminous element and control the luminance of luminous element or store the excessive power. When the banner of the present invention is deformed or vibrates due to the airflow, the embedded transducer will transforms the mechanical energy into electrical energy to power the luminous element. In comparison with the conventional banner that requires extra lights connected to a power cable, the self-powered luminant banner of the present invention is both convenient to use and cost-effective, as well as provides safer application.
