The air holes 21 are located above the arc-shaped water storage tank 7 .

The heat-dissipating aluminum profile is provided with a heat-dissipating cavity, and is provided with communicating holes and ventilation holes, which will have the effect of an air circulation cycle while the aluminum profile dissipates heat, and the heat will be taken away through the circulation, increasing the heat dissipation efficiency and improving the heat dissipation effect; further , due to the setting of air holes and connecting holes, if it is used outdoors, there will be a problem of rainwater penetration. The setting of the water baffle can prevent rainwater from dripping down along the water baffle and prevent it from entering the LED lamp; further, There is an arc-shaped water storage tank. When it is installed outdoors, part of the water will be stored in it when rainwater enters, which can accelerate heat dissipation when the light is on; further, each air hole is set above the arc-shaped water storage tank. Can maximize water storage.
