LED street lights have quickly occupied the domestic market. While using LED street lights extensively, LED street light manufacturers cannot ignore the defects of LED lights due to technical reasons.
First of all, the heat dissipation part. Although the heat dissipation problem of LED lights has been initially solved, good heat dissipation also indicates that the weight of the entire LED lamp is too high, and the price will increase accordingly. The heavy lamp holder will still hinder the popularization of LED street lights.
Secondly, the modularization of LED lights is a major trend, and the effect is obvious to all, but its reliability still needs to be strengthened.
At present, the technology of led lights is gradually mature. The heat dissipation of led lights is well controlled so far. Even after 5000 hours of work, the luminous decay is still small, and the luminous efficiency can reach more than 70%. However, for high-power LED lamps, the heat dissipation problem is not easy to solve, and the luminous decay is large, and the luminous efficiency will drop to 30%. If you want to increase the voltage and current to improve the luminous efficiency, it is easy to cause the LED chip to be damaged.
The led lamp is energy-saving, environmentally friendly, easy to adapt to low voltage, and can also be directly matched with the solar system, without additional inverter and conversion processes, and can achieve the maximum energy utilization rate. But there are also shortcomings. Its illumination angle is small and uneven, the color rendering index is low, and the optical and heat dissipation design is complicated.
LED lights have advantages and disadvantages, but compared to traditional street lights, they are still a better light source with a wider range of applications. We believe that with the improvement of technology, LED lights will definitely become a dazzling light in the lighting industry.
