The following parameters are for reference only.Specific parameters can be customized according to actual needs.

Traffic Signal Light Technical Parameters

1.Basic Parameters

Light Source Type:Mainstream LED(long lifespan,low power consumption)'Single light power is 1-3W,and total lamp power(sum of red/yellow/green color) is ≤15W.

Luminous Flux:Red ≥ 150lm,yellow ≥ 200lm,green ≥ 250lm(ensuring clear visibility at long distances).Light intensity distribution complies with GB 14887 standard,with vertical/horizontal viewing angles≥30° and no blind spots.

Color Temperature/Wavelength:Red 620-660nm,yellow 585-595nm,green 500-560nm.High monochromatic purity prevents color mixing for accurate signal recognition.

Light-Emitting Surface (LES) Size:Standard Φ200mm(main intersection signals) and Φ100mm(pedestrian crossing signals).LES transparency is ≥ 90%with no obstructions to light output.

2.Structural Safety Parameters

Lamp Body Material:Lamp housing is made of ABS engineering plastic (impact-resistant) or aluminum alloy (rust-proof).The lampshade is polycarbonate (pc)for impact resistance and UV protection.

Protection Class:IP65 for the entire lamp (resistant to heavy rain and duat);IP54 for terminal blocks(splash-proof) to prevent short circuits caused by rainwater  infiltration.

Wind Vibration Resistance:Wind resistance ≥ Grand 12 ---lamp poles are mostly Q235 steel with a well thickness of 3-6mm,ensuring no shaking under strong winds.Vibration resistance ≥ Grade 6 to withstand road vibrations.

3.Electrical Control Parameters

Input Voltage:AC 220V±10% (compatible with municipal power grids),operating frequency 50Hz.Standby power consumption ≤ 1W for low controller energy use.

Lighting Mode:Constant current driving is supported to avoid brightness changes caused by voltage fuctuations.Flashing frequency is 50-60 times per minute (for warning modes,eg.yellow flash signals).

Control Method:Wired control (connected to traffic signal controllers for timing-based switching) and wireless linkage (eg,with pedestrian request buttons or vehicle detectors) are supported.Switching response time ≤ 0.5s with no delay.

4.Environmental Adaptation Parameters

Operating Environment:Works at -40℃ to 70℃ (adapting to severe cold in northern regions and high temperatures in southern regions) and humidity ≤ 95% (no condensation ).Functions normally in harsh weather like heavy rain and sandstorms.

Service Life:LED ligght source lifespan ≥ 50,000 hours (usable for over 11 yeara at 12 hours of daily operation);controller lifespan ≥ 8 years.

Weather Resistance:The lampshade resists UV aging (no yellowing or cracking after 5 years of exposure).The lamp body is corrosion-resistant,passing a 48-hour salt spray test for suitability in coastal areas.
