Traffic lights mainly consist of four parts: the light head, the light pole, the control system, and the power supply system.
Lamp Head: Contains red, yellow, and green LED or halogen bulbs. Modern lamps often use high-brightness LED modules, featuring energy saving and a long lifespan (typically over 50,000 hours). The lampshade is made of polycarbonate with a light transmittance of ≥80% and includes a glare shield.
Lamp Pole: Commonly made of steel octagonal or round poles, 6-12 meters high, with a hot-dip galvanized surface (zinc layer ≥80μm) and powder-coated for corrosion protection. Some intersections use cantilever structures with crossarm lengths up to 15 meters, requiring wind load testing (wind resistance ≥40m/s).
Control System: Includes traffic signal controllers (core is PLC or microcontroller), vehicle detectors (inductive loop/radar), communication modules (4G/fiber optic), etc. Must comply with GB25280-2016 standard, supporting multi-time-period timing schemes and remote control.
Power Supply System: Primarily 220V AC mains power, equipped with UPS backup power (≥2 hours of runtime). Solar power (≥400W photovoltaic panel power) is optional for some remote areas.
Additional components may include countdown displays, pedestrian crossing buttons, and mounting positions for surveillance cameras. The entire system must be IP65 certified, with a typical operating temperature range of -40℃ to +75℃. We currently offer traffic light poles, octagonal monitoring poles, and other traffic facility products made of high-quality steel, with an IP65 protection rating and an operating temperature range of -45℃ to 65℃. Lifetime after-sales service is provided.
