The original street lamps in Jintan District were mainly high-pressure sodium lamps. Long-term operation has led to serious light decay and high energy consumption, which not only affects nighttime driving safety, but also restricts the sustainable development of the city. Donlim Power focuses on user pain points and launches a comprehensive solution of "intelligent dimming + on-demand lighting" based on the programmable technology of the MXG series power supply. Through core functions such as positive and negative logic dimming and timing control, the illumination is dynamically adjusted based on parameters such as road grade, traffic flow, and ambient brightness. While ensuring nighttime traffic safety, the overall energy-saving efficiency is increased by more than 40%, making each street lamp a "thinking energy-saving guard."
