Research on Energy-Saving Indicators for Urban Road LED Lighting
GUO Yanping
Abstract：By analyzing the definition and calculation methods of energy-saving indicators for road lighting,the influencing factors of energy-saving indicators are analyzed.The energy consumption differences between high-pressure sodium lamps and LED street lamps are quantitatively studied,and different LED street lamps are selected for application in typical road scenarios.The influences of luminous efficacy,photometric type,and layout method on energy consumption are analyzed and discussed.Measures to improve the energy-saving level of LED road lighting are studied,and the recommended values of power density for LED road lighting are proposed.
