Yes, PWM dimming technology is one of the most popular LED street light brightness control technologies. PWM technology uses a switching circuit to perform frequency modulation by controlling the ratio of the LED’s working time. This technology can achieve efficient brightness adjustment with a wide adjustment range, has less impact on the working life of the LED, and also has strong anti-interference ability. However, this technology requires the use of switching circuits. It may cause a certain amount of electromagnetic interference, and the problem of pulse noise needs to be improved.
I learned that the lifespan of LED street lights will be reduced if they have poor performance on heat dissipation. How do LED street lights manage to dissipate heat?
