High-brightness LED lamp aluminum substrate

The invention relates to the technical field of aluminum substrates, in particular to a high-brightness LED lamp aluminum substrate which comprises an aluminum substrate body, two fixing blocks are fixedly mounted on the outer wall of the aluminum substrate body, mounting mechanisms are arranged on the two fixing blocks, and the aluminum substrate body is composed of a plurality of aluminum substrate ring pieces, a ventilation plate and a flexible connector. A control device is arranged on the back of the ventilation plate and comprises an air cylinder and a rotating mechanism, the rotating mechanism can adjust the orientation of the aluminum substrate body, ventilation holes are formed in the ventilation plate, and the ventilation holes suck air or spray air in the front-back movement process of the air cylinder so that dust on a lampshade and dead bodies of small insects can be cleaned. According to the LED lamp, the process of installing the aluminum substrate body is easier and more convenient, convenience is brought to installation personnel, meanwhile, the installation is stable, the LED lamp is safer in the long-time use process, and the lamp cover can be kept clean while illumination can be conducted only in a specific range.
