The technical development status of LED street lights

The LED street lights currently launched have a variety of product appearances, the arrangement and quantity of LED luminous particles, the external dimensions and internal designs of the rectifier circuit.

The power supply assembly also has its own integrated power supply and external power supply, and the heat dissipation technology has its own advantages, which brings great inconvenience to the operation and maintenance work after popularization, and does not meet the standardization and universal design of municipal utilities in principle.

Optical design and heat dissipation are the main technical problems faced by LED street lights. At present, the radiation forms of LEDs are Lambertian, side-fired, bat wing, rectangular, butterfly wing and concentrating type. Through the secondary optical design, the illumination range and luminosity curve of the LED can meet the needs of road lighting.

China's LED road lighting market mainly relies on government demonstration project procurement, which is highly dependent on policies. In addition to the impact of the performance and installation cost of LED street lights on its marketization, a sound market environment and mature business development model have also become the key to whether the market can maintain a healthy development.

With the continuous maturity of technology, the energy-saving effect of LED street lamps has become increasingly prominent, especially the intelligent control characteristics of LED not only strengthen the advantages of LED street lamp products, but also greatly enhance the energy-saving space of road lighting systems. Therefore, under the current background of energy saving and emission reduction, local governments have widely promoted LED street lamp products.

Benefiting from favorable factors such as government procurement of key projects and the continued large-scale promotion of LED street lighting construction, the LED street lighting series index has shown a continuous upward trend recently, which has greatly stimulated the LED street lighting market.
