Dustproof and waterproof multipurpose LED-light power source assembly and dustproof and waterproof LED light

摘要

A dustproof and waterproof multipurpose LED-light power source assembly comprises a heat sink, a heat-dispersal fan, a circuit board driver module, an LED light source module, a power-source casing top cover and a power-source casing bottom cover. The LED light source module comprises plural LED chips and an LED heat-dispersing substrate. The heat-dispersal fan is a dustproof and waterproof fan. The heat sink comprises a baseboard to which the LED heat-dispersing substrate is fixedly connected and conducts dispersed heat. At the center of the top of a heat-dispersal member, a space is provided to accommodate the heat-dispersal fan. The power-source casing bottom cover is positioned above the heat-dispersal fan and is fixedly connected to the heat sink. The power-source casing top cover and the power-source casing bottom cover are hermetically connected one to the other. A waterproof bolt assembly is connected to the top of the power-source casing top cover.
