The rotary-type photoelectric separation heat dissipation LED floodlight provided with the protection pendant chain comprises an LED light supply, an LED power supply, a floodlight shell body and a floodlight lampshade. The LED power supply comprises a circuit board, a power supply box body and a power supply box cover. A vacant unit is installed on the circuit board independently and vertically. At least three groups of connecting holes used to fix the power supplies are arranged on a baseboard of the power supply box body, and each group of connecting holes is formed by a same bar-type hole and a same U-shaped hole. The vacant unit in the rotary-type photoelectric separation heat dissipation LED floodlight provided with the protection pendant chain can independently change, and further improves heat dissipation effect. The mounting holes of the power supply comprise bar-type holes and U-shaped holes, a plurality of mounting ways are increased, and therefore rotary-type photoelectric separation heat dissipation LED floodlight provided with the protection pendant chain is applied to various mounting situations.
