Abstract

The invention discloses a protective device for heat-dissipation failure on LED lighting module comprising a LED light set, a power supply unit and a cooling fan. The cooling fan connects to a main power supply circuit by a series circuit or a parallel circuit and an electrical circuit is set between the main power supply circuit and the cooling fan. Current control components, such as field-effect transistors, transfer resistor, relay or thyristor, are provided between the electrical circuit and the main power supply circuit. When the operation state of cooling fan of for LED lighting module is unusual, the current supplied by the main power supply circuit will be lowered down or shut off by actuator response of the electrical circuit and the current control components for making up light of the LED lighting set weak or none. Protective effects of preventing the LED lighting set from damage and blasting due to overheat for raising usage safety and quality of using LED lighting module so as to be provided with practical progress.
