Problems solved by technology

The above three kinds of LED street lights represent the mainstream of LED lighting technology on the market, including tunnel lights and street lights. Secondary optical processing components, such as secondary optical lenses or reflectors, the structure of the lamp is complex and affects direct heat dissipation; on the other hand, the existing technology uses profiles as the main heat dissipation components, and profiles are mostly processed by extrusion. Due to technical reasons , the cooling fins cannot be processed very thin, and the spacing of the cooling fins cannot be set very small, so the total effective cooling area is small and the cooling effect is limited
