Description

Product Introduction

Large-scale solar street lights use high-power LED modules and precision optical design to achieve high-brightness, long-distance, and wide-coverage lighting effects, significantly superior to traditional street lights.
Industrial-grade LED chips and full encapsulation technology are adopted to balance high luminous efficiency, low light decay, and wide temperature range stability, meeting the long-term operation needs in extreme environments.
The fully sealed structure and high-strength materials, certified with IP65 waterproof and dustproof ratings, ensure stable operation of the equipment in extreme conditions.
Through environmental sensing and adaptive algorithms, demand-based lighting, remote monitoring, and fault early warning are realized, reducing operation and maintenance costs.

Wide-Area Lighting and High-Brightness Output

Core Parameters of Lighting Performance

Indicator	Parameter	Technical Advantages
Light Source Power	150W–300W (expandable to 500W)	Supports multi-bead parallel connection to meet high-brightness needs of main roads, ports, and squares.
Luminous Flux	≥24,000lm (150W) to ≥80,000lm (500W)	Brightness increased by 200% compared to traditional high-pressure sodium lamps at the same power, with 60% energy consumption reduction.
Average Illuminance	≥30lux (main road standard)	Meets the requirements of Class I roads in CJJ 45-2015 Urban Road Lighting Design Standard.
Irradiation Range	Diameter 40–60m (beam angle 120°×60°)	Single lamp covers 1,200–2,800 m², reducing lamp post density and installation costs.
Color Rendering Index (Ra)	≥80 (customizable Ra≥90 version available)	Simulates natural light, enhancing night driving and pedestrian safety while reducing traffic accident rates.
Color Temperature	4000K–6500K (adjustable)	Supports switching between cool white (5700K) and neutral light (4000K) for different scenarios.

Optical Design Breakthroughs

Asymmetric Light Distribution Lens:

Uses free-form surface lens technology to precisely control the beam angle at 120°×60°, creating rectangular light spots to avoid light pollution and energy waste.

Multi-Stage Reflector Structure:

Utilizes a nanoscale electroplated reflective layer to increase light utilization to over 95%, a 20% improvement over traditional street lights.

Dynamic Spot Compensation:

Supports intelligent angle adjustment (±15° pitch angle) to adapt to different road slopes and widths.

High-Quality LED Beads

Core Parameters of LED Beads

Indicator	Parameter	Technical Advantages
Chip Type	Customized high-power LEDs (e.g., Cree XP-G3, Lumileds Luxeon TX)	Electrostatic resistance >8kV, reducing risks of lightning and surge damage.
Luminous Efficacy	≥190lm/W (industry average: 120–150lm/W)	Brightness increased by 30%–50% at the same power, reducing requirements for solar panels and battery capacity.
Light Decay Rate	≤2%/10,000 hours (L70 standard)	Lifespan >60,000 hours, supporting 10 years of maintenance-free operation.
Operating Temperature	-40℃ to +85℃ (luminous efficacy fluctuation <5% across full temperature range)	Adaptable to extreme cold (e.g., Siberia) and high-temperature (e.g., Middle Eastern deserts) environments.
Protection Process	Full-potting silicone + ceramic substrate	Sulfide-resistant and salt spray corrosion-resistant, suitable for coastal and industrial pollution areas.
Drive Mode	Constant current drive (efficiency ≥95%)	Supports PWM dimming and overvoltage protection to prevent bead overheating and damage.

Optimized Bead Layout

Honeycomb Array Design:

Divides the single-lamp module into 16–32 independent light-emitting units, where a single bead failure does not affect overall lighting. MTBF (mean time between failures) >100,000 hours.

Intelligent Zoning Dimming:

Uses multi-channel driver chips to divide the lamp panel into 4–8 independent zones, dynamically adjusting brightness based on traffic and pedestrian distribution (e.g., reducing brightness to 50% when no vehicles are detected).

IP65 Protection Rating

Technical Analysis of IP65 Protection

Dustproof Design

● Ultrasonic welding + sealing rubber rings provide dual protection at lamp body joints, preventing dust from entering the interior.

● Compliant with IEC 60529 standards, capable of continuous operation in sandstorms (wind speed >20m/s).

Waterproof Design

● Terminal interfaces use IP68 waterproof connectors, supporting short-term immersion (1m water depth, 30 minutes).

● Independent sealing of the battery compartment and controller compartment prevents condensate from eroding circuits.

Anti-Corrosion Design

● Lamp body adopts 3mm-thick aluminum alloy die-cast housing with surface anodizing, resistant to salt spray corrosion for >1,000 hours.

● Fasteners use 316L stainless steel to avoid rust and breakage.

Extreme Environment Test Validation

High-Temperature and High-Humidity Test

Continuous operation for 1,000 hours at 85℃/85%RH results in light decay <3% and insulation resistance >100MΩ.

Low-Temperature Impact Test

After standing at -40℃ for 24 hours, the lamp beads light up normally without cracking or dark areas when powered on immediately.

Vibration Test

Passes GB/T 2423.10 standards (frequency 10–55Hz, amplitude 1.5mm) with no structural looseness or changes in optical performance.

Product Advantages

Large-scale solar street lights achieve wide-area lighting, high reliability, and environmental adaptability through high-power light sources, efficient photovoltaic components, and high-protection designs, meeting the needs of high-load scenarios such as main roads, industrial zones, and ports.
