摘要：

With the continuous expansion of the scale of urban lighting, LED (light-emitting diode) lamps with a long life, high luminous efficiency, in many cities gradually popularized into the practical stage. In the traditional AC power system, the driving power of LED is the main failure point of LED lamps, and it has a huge maintenance cost. Aiming at this problem, this paper presents a scheme of DC power supply system forLED road lighting, and analyzes the key problems such as DC protection and power supply distance, and makes anenergy efficiency comparisoncomparison with sodium lamp and AC power supply LED lamps.It is concluded that the DC power supply system is a reasonable choicefor urban lighting.
