Description

Product Introduction

Energy Saving and Environmental Protection: Utilizes monocrystalline silicon solar panels with ultra-high conversion efficiency, paired with MPPT controllers and long-life lithium iron phosphate batteries. The BMS system ensures wide-temperature operation, significantly reducing grid dependence. The wire-free design minimizes construction carbon emissions.
Excellence in Optical Performance: Uses imported high-color-rendering LED chips (Ra≥90), combined with optical lenses and reflector cups, to achieve a visibility distance of over 500 meters under strong or backlight conditions. The dual-layer optical structure with specific wavelength packaging ensures a signal visibility distance of 200 meters in harsh weather like thick fog-twice that of traditional traffic lights.
Reliable Operation in All Climates: IP65-protected aluminum alloy housing, supplemented by nano-coatings, three-proof paint circuit boards, independent heat dissipation air ducts, and 10kV lightning protection modules, adapts to extreme temperatures (-40°C to 85°C), high salt fog, and strong UV environments.
Power Supply Safety Redundancy: Parallel dual-battery packs enable seamless fault switching. Supercapacitors ensure continuous power supply for ≥0.5 seconds. It also supports mains access and manual switching to guarantee stable power supply in extreme weather.

Energy Saving and Environmental Protection

● Integrated Photovoltaic-Energy Storage Design

Uses monocrystalline silicon solar panels (conversion efficiency ≥21.5%) and MPPT controllers, paired with lithium iron phosphate battery packs (cycle life ≥3000 times) to achieve all-weather efficient power generation and energy storage.

The BMS system ensures stable battery operation in -20°C to 60°C environments, reducing grid dependence by over 90%.

● Full-Lifecycle Carbon Emission Reduction

Annual power generation per system is approximately 1200kWh, equivalent to reducing 1.1 tons of CO₂ emissions. Over a full lifecycle (10 years), it can reduce emissions by 11 tons-equivalent to planting 600 trees.

Its wire-free design avoids road excavation, further reducing construction carbon emissions.

Optical Performance

● Ultra-High Color Rendering LED Light Source

Uses imported high-color-rendering LED chips (Ra≥90), combined with optical lenses and reflector cup design, to ensure clear signals under strong or backlight conditions. Visibility distance remains over 500 meters even under direct noon sunlight.

● Enhanced Penetration Technology

Dual-layer optical design (anti-UV high-transmittance PC cover + nano anti-reflective coating) and specific wavelength packaging (red light 590-620nm, green light 520-550nm) significantly enhance signal penetration in fog, rain, and snow. In thick fog, the visibility distance reaches 200 meters-twice that of traditional traffic lights.

System Reliability

● All-Climate Protection

IP65-protected aluminum alloy housing, nano-coatings, three-proof paint (moisture/dust/salt fog)-coated circuit boards, and independent heat dissipation air ducts ensure stable operation in -40°C to 85°C environments, salt fog corrosion (≥1000 hours), and UV aging (≥5000 hours).

Built-in lightning protection module (surge protection ≥10kV) withstands lightning strikes and grid fluctuations.

● Redundant Power Supply Assurance

Parallel dual-battery pack design enables seamless switching to backup batteries in case of main battery failure.

Built-in supercapacitors provide ≥0.5 seconds of continuous power supply. Supports external mains interfaces and manual switching of power modes in extreme weather.
