12v Led Street Light

Product Introduction

The 12V LED street light integrates advanced monocrystalline silicon photovoltaic cells, smart LED information screens, mercury-free eco-friendly light sources, and a safe 12V low-voltage power supply system. It features:

• An integrated solar power supply system (monocrystalline silicon cells + lithium battery energy storage);
• High luminous efficiency LED light sources (luminous efficacy ≥160lm/W);
• Intelligent light control, remote management, and mercury/lead-free environmental design;
• Support for 8–12 hours of continuous operation during rainy days;
• Light decay ≤10% over 5 years, with an 85% reduction in carbon emissions compared to traditional street lights.

Advanced Monocrystalline Silicon Photovoltaic Cells

• Technological Breakthroughs in Photovoltaic Cells

Monocrystalline PERC Technology: Uses 210mm large-size monocrystalline PERC cells (brands: LONGi, JinkoSolar) with a conversion efficiency ≥22.8% (5% higher than traditional polycrystalline silicon). Single panel power reaches 320W (dimensions 1956×992×35mm), supporting parallel expansion for multiple panels.

Bifacial Power Generation Design: The backside of the cells is coated with a silicon nitride anti-reflective film to utilize ground-reflected light, increasing comprehensive power generation by 10%–20%, suitable for high-reflectivity scenarios like snow or sand.

• Intelligent Charging Management

MPPT Maximum Power Point Tracking: Built-in smart controller (supporting PWM+MPPT dual modes) tracks the maximum power point of photovoltaic cells in real time, with a charging efficiency ≥97%-15% higher than traditional PWM controllers.

Multi-Stage Charging Strategy: Supports three-stage switching between constant current charging (CC), constant voltage charging (CV), and floating charging (Float), extending lithium battery life to over 8 years.

• Environmental Adaptability Optimization

PID Resistance: The cell surface uses an aluminum oxide passivation layer, enhancing potential-induced degradation (PID) resistance by 90% to ensure power attenuation ≤20% over 25 years.

Anti-Shadow Design: Through cell parallel connection + bypass diode design, it maintains ≥80% power generation efficiency even under partial shadow occlusion.

Smart LED Information Screen

● Screen Architecture and Performance

P3 Full-Color LED Screen: Uses SMD1921 lamp beads (brand: NationStar), with a pixel pitch of 3mm, brightness ≥5000cd/㎡, 16-bit grayscale display, and a refresh rate ≥3840Hz for flicker-free operation.

Split Design: The screen and street light body adopt a magnetic quick-release structure for independent maintenance and upgrades. Screen power consumption ≤80W (12V power supply), 60% more energy-efficient than traditional P10 screens.

● Intelligent Content Management

4G/WiFi Dual-Mode Communication: Built-in industrial-grade communication modules (supporting China Mobile OneNET and Huawei Cloud IoT platforms) enable remote content updates (text, images, videos), brightness adjustment, and fault alarms.

Environmentally Adaptive Display: Equipped with photosensitive and temperature/humidity sensors, it automatically adjusts screen brightness (100–5000cd/㎡) based on ambient light intensity and switches to high-contrast display mode in rainy/foggy conditions.

 

● Expanded Application Scenarios

Public Information Dissemination: Supports real-time pushing of government announcements, weather forecasts, and traffic information.

Advertising Revenue: Enables time-sharing ad placements to create additional revenue for operators.

Emergency Command: Links with public security and fire-fighting systems to automatically play escape guidelines in emergencies.

Energy-Saving and Environmental Protection Design

• Environmental Features of LED Light Sources

Mercury/Lead-Free Packaging: Uses silicone + ceramic substrate packaging, completely free of hazardous substances like mercury and lead, compliant with RoHS 2.0 and REACH regulations.

Recyclable Materials: The lamp body aluminum uses 6063-T5 recycled aluminum alloy with anodized surface treatment, achieving a recycling rate ≥95%. The PCB board uses halogen-free FR-4 substrate, emitting no dioxins when burned.

• Ultra-Low Energy Consumption and Carbon Emission Reduction

Luminous Efficacy ≥160lm/W: 37.5% more energy-efficient than traditional high-pressure sodium lamps (100lm/W), with 12V system transmission losses 60% lower than 220V systems.

Carbon Footprint Calculation: Annual power consumption per lamp ≤120kWh (12 hours of daily lighting), reducing carbon emissions by 0.12 tons/year compared to traditional street lights (based on thermal power carbon emission factor of 1kg/kWh).

• Eco-Friendly Design

Anti-Glare and Low Light Pollution: Uses batwing light distribution lenses (120°×60°) with ground illuminance uniformity U0≥0.4 and upward light flux ≤2%, avoiding interference with starry skies and wildlife habitats.

Silent Operation: Fanless heat dissipation design with noise ≤25dB(A), suitable for silent environments like scenic areas and sanatoriums.
