AI Technical Summary
The existing streetlights are not securely connected to the poles, making them prone to displacement. They also have poor heat dissipation, which causes the lamps to shake and become damaged. In severe cases, they may even fall off. Prolonged operation can also lead to increased heat in the lamps, affecting their lifespan.
A long-life, high-heat-dissipation LED street light head was designed, which adopts a connecting block, a locking mechanism and a heat dissipation mechanism. The thickness of the heat sink is optimized by gradient material distribution to form a thin three-dimensional shape. Combined with the light reflection path, the heat dissipation effect is improved, and the locking mechanism is used to securely connect the lamp body to the lamp pole.
This achieves a stable connection between the lamp body and the lamp post, improves heat dissipation, extends the lifespan of the LED street light, and enhances the aesthetic appearance and functional adaptability of the lamp head.
