Both the lamp post and the elbow are hollow pipes, and the feature is that both ends of the elbow are air inlets. , the welding place at the upper end of the elbow communicates with the lamp post, there are gaps between the two side panels or four side panels of the light source installation plate and the lamp housing, and there are multiple ventilators on the two side panels or four side panels of the light source installation Holes, multiple ventilation holes on the light source mounting plate, multiple ventilation holes on the lamp post, and bent pipes form a natural heat dissipation channel. The air will take away the heat through the natural heat dissipation channel from bottom to top. The heat dissipation effect is good, and the service life of the street lamp is long. And the overall structure is stable, high strength, easy to install and maintain.

Further, the gap between the two side panels or four side panels of the light source mounting plate and the lamp housing is 5-30 mm, and a protective net is provided on the through hole of the light source mounting plate to quickly dissipate the heat inside the lamp holder to prevent Dust-proof, insect-proof, waterproof and air-permeable, which improves the service life of the lamp holder.

The lampshade adopts the shape of an airplane to make the street lamp beautiful in shape. The lower end of the lampshade is provided with a plurality of LED lamp beads, which improves the lighting range and is suitable for street lamps in various occasions.

The LED light source board is a horizontal arc-shaped board, and the LED light source board is provided with a plurality of through holes for installing LED lamp beads in a dot matrix, which improves the street lighting effect, uniform illumination, less dark lighting areas, and increases the effective irradiation area , saves energy, and enhances the internal heat circulation of the lamp head, which is convenient for heat dissipation.

The nozzle of the lamp post connected to the lamp head is provided with a protective net, which is a corrosion-resistant, fine-grained air-permeable net, dust-proof, insect-proof, waterproof, breathable, and has a long service life.

This street light uses air to circulate with the atmosphere inside the lamp post, elbow, and lamp holder to take away the heat emitted by the LED lamp, which protects the LED lamp and greatly reduces the temperature inside the lamp, improving the service life of the lamp. Stable performance and high luminous efficiency; the aircraft-shaped outer cover has excellent decoration and aesthetics, and is suitable for street lights in various occasions.
