The wind turbine or the heat flow actuated turbine type axial fan has a closed top portion and a plurality of radial discharge vanes which are overlapped at the same oblique angle with each other, and are arranged around the shaft To the airflow inlet, if there is no wind force, if the electric axial fan fan pumps the airflow to the inside of the turbine airshield, the turbine formed by the drafting blade can be rotated, and the axial airflow inlet is sent. The incoming airflow is discharged to the surroundings; The heat generating device currently disposed inside the closed space, such as a high-power lamp set, is usually composed of a heat-conductive material and has a closed top as a heat-dissipating case to facilitate heat dissipation and prevent rainwater from entering. The present invention is a heat-dissipating lamp housing on the top of the lamp. An electric axial fan driven by electric energy is used to feed the airflow into the interior of the turbine waterproof cover. When the electric axial fan is running, the airflow is converged from the outer side of the top of the sealed lamp housing to the middle of the lamp housing, and the turbine is waterproofed upward. The axial airflow inlet on the lower side of the cover is discharged to the surroundings by the radial exhausting vane of the turbine type waterproof cover. In the use of high-power lamps such as high-power LED lamp sets, the top of the LED lamp housing can be heated. The external cooling airflow cooling does not hinder the waterproof sealing effect. When the external wind power drives the turbine waterproof cover for rotation, the heat dissipation effect can be further increased.

The latter cooling fan is more difficult to prevent rainwater, and an electric axial fan with a turbine waterproof cover is not seen at the top of the lamp housing. The shell is cooled by an externally cooled airflow and has a function of preventing rain.

The new type is designed to protect the top of the enclosed heat-dissipating lamp housing of high-power lamps. The electric axial fan of the turbine-type waterproof cover of water, when the electric axial fan is energized, the top airflow flows through the closed heat-dissipating lamp shell to the middle of the top of the lamp shell, and enters the turbine-type waterproof cover upwards. The axial airflow inlet on the side is discharged to the periphery via the radial exhausting vane. In the use of the high-power lamp, the hot-cooled air-cooling type of the lamp housing can be used to form an external cooling airflow cooling effect without hindering the waterproof sealing effect. .
