Description

Product Introduction

◎Advantages of monocrystalline silicon solar panels: Solar Security Street Lights adopt M10 monocrystalline silicon cells, achieving an actual conversion efficiency of 22.1% through technologies such as PERC. They generate 35% more electricity than traditional polycrystalline silicon, perform better in extreme environments such as high temperatures, low light, and impact resistance, and have a lifespan of over 25 years.

◎High-density LED lamp bead matrix: 144 CREE XP-G3 LED chips paired with PMMA lenses achieve 20,000 lumens of brightness, CRI 82 color rendering, and 160lm/W luminous efficiency. Compared with traditional solutions, the brightness is increased by 150%, the lifespan is extended by 3.3 times, and it supports intelligent dimming and anti-glare design.

◎System energy efficiency and cost comparison: The combination of monocrystalline silicon and LED matrix increases the average daily power generation by 78%, reduces the battery capacity by 50%, and combined with the 10-year maintenance-free feature, the total cost over 10 years is 49% lower than that of traditional solutions, with an investment payback period of only 2.8 years.

Monocrystalline Silicon Solar Panels

Solar Security Street Lights use monocrystalline silicon cells. Through PERC (Passivated Emitter and Rear Cell) technology, 12BB (12 busbars) design, and anti-PID (Potential Induced Degradation) coating, they achieve a laboratory conversion efficiency of 23.5% and an actual working condition efficiency of 22.1%, which is more than 35% higher than traditional polycrystalline silicon.

◎Frame: Anodized aluminum alloy, corrosion resistance grade WF2 (can resist 5% salt spray concentration environment), with a lifespan of over 25 years.

High-Density LED Lamp Bead Matrix

Security lighting needs to meet three core requirements: high brightness (>10,000 lumens), high color rendering (CRI>85), and long lifespan (>50,000 hours).

Solar Security Street Lights use CREE XP-G3 LED chips + PMMA (polymethyl methacrylate) lens arrays. Through 144 lamp bead zoning control, 90° beam angle, and intelligent dimming strategy, they achieve a peak brightness of 20,000 lumens, a coverage radius of 15 meters, and a luminous efficiency of 160lm/W, saving 75% energy compared with traditional high-pressure sodium lamps.

(1) Lamp Bead Performance

Model: CREE XP-G3 S5 (cool white 6500K)

Luminous efficiency: 160lm/W (industry average 120lm/W)

Color rendering index: CRI 82 (traditional sodium lamp CRI <20)

Lifespan: L70 (brightness attenuation to 70%) >100,000 hours (estimated by TM-21 standard)

(2) Optical Design

Lens material: PMMA (light transmittance 93%), with AR (anti-reflection) coating on the surface, light loss <5%;

Beam angle: 90°×120° batwing light distribution, road surface uniformity >0.7 (national standard ≥0.4);

Anti-glare: Using cut-off lampshade, UGR (Unified Glare Rating) <16 (road lighting standard ≤22).

(3) Intelligent Dimming Strategy: On-Demand Lighting and Maximum Energy Efficiency

◎Time mode: Automatically turn on/off according to sunrise/sunset time, supporting time-segmented brightness adjustment (e.g., reducing to 50% after 22:00);

◎Environmental mode: Detect ambient brightness through a photosensitive sensor, and automatically increase brightness by 20% on cloudy and rainy days;

◎Motion mode: Integrate millimeter-wave radar to trigger full-power lighting (20,000 lumens) when detecting humans/vehicles, and resume 2,000 lumens energy-saving mode when no one is present;

◎Energy efficiency improvement: The comprehensive dimming strategy reduces the average daily power consumption by 65%, and the battery life is extended by 2.9 times under the same battery capacity.
