LED traffic lights are traffic signal lights that use LED (light-emitting diode) as the light source, and have the advantages of energy saving, environmental protection, long life, fast response, and bright colors. LED traffic lights are widely used in various countries and regions, but different countries or regions may have different standards or specifications to regulate their performance, quality, safety, and other aspects. According to the web pages I searched for you, here are some brief introductions of some international standards for LED traffic lights:International Electrotechnical Commission (IEC)1: IEC is an organization that develops international standards for electrical and electronic fields, and its members include national electrotechnical committees from more than 160 countries and regions. IEC has issued several standards related to LED traffic lights, such as IEC 60809:20142 “Road vehicles - Lamps - Performance requirements”, IEC 62722-2-1:20143 “Luminaires - Part 2-1: Particular requirements - LED modules”, etc.
European Committee for Standardization (CEN): CEN is an organization that develops technical standards that are followed by European countries, and its members include national standardization bodies from 33 European countries. CEN has issued several standards related to LED traffic lights, such as EN 12368:2015 “Traffic signal controllers”, EN 50556:2011 “Road traffic signal lights and variable message signs - Photometric properties of signals”, etc.
American National Standards Institute (ANSI): ANSI is an organization that develops technical standards that are followed by various industries in the United States, and its members include representatives from government, business, academia, consumers, and other fields. ANSI has issued several standards related to LED traffic lights, such as ANSI/IESNA RP-8-14 “Roadway and Public Area Lighting Design Guide”, ANSI/IES LM-79-08 “Electrical and Photometric Measurements of Solid-State Lighting Products”, etc.
