LED street lights are more humane
The general production method of domestic manufacturers is close-packed high-power and high-efficiency LEDs, coupled with outsourcing LED drive power supplies. Early products mostly advertised how high their luminous efficiency is and how long the LED life span is. But in fact, the life of LED does not represent the life of the lamp, and high luminous efficiency does not mean energy saving. In practical applications, we often encounter the phenomenon that the lighting effect of the LED street lamp is reduced a lot or even goes out after the lamp is turned on for a long time. Since the light distribution of LED lamps directly determines the lighting in practical applications, we should use the value of W/km to measure the energy-saving level of the product. LED street lights are products with the highest technical requirements. Batwing's light distribution, lightning protection, heat dissipation of high-power products, drive power, waterproof and dustproof, high and low temperature application environment, and the way of lighting the main and secondary roads all determine the quality of the product.
Due to the high brightness of LEDs, people are susceptible to interference from street lamp glare during driving, which should be avoided in actual design. Early selection of sodium lamp as the ideal street light source, one of the considerations is that the double yellow lines of yellow light are sensitive to human eyes and have strong fog penetration ability. But now the color temperature of LED products can be selected from low to high specifications, so that the right color temperature can be selected more correctly in combination with the light and dark visual environment of the human eye. Coupled with ensuring that there is no light pollution caused by upward light, it has the function of intelligent lighting control to reduce consumption when the traffic is idle in the middle of the night, which can further achieve the effect of energy saving and emission reduction.
