Led Street Light 300w

Product Introduction

◎Breakthrough in lamp bead technology: The 300W LED street light uses 1,200 high-power lamp beads, achieving a luminous efficiency of 180lm/W through three-dimensional arrangement and liquid cooling. With a lifespan exceeding 100,000 hours, it saves 40% energy compared to traditional high-pressure sodium lamps and reduces maintenance costs by 80%.

◎Dominance of monocrystalline silicon: The monocrystalline silicon solar panels boast a mass-produced efficiency of 23.5%, significantly outperforming polycrystalline silicon in low-light performance and temperature adaptability. With a degradation of <15% over 25 years and a levelized cost of energy (LCOE) as low as 0.18 yuan/kWh, they are ideal for high-density energy demand scenarios.

◎Intelligent energy management: The MPPT controller enables three-stage charging and dynamic power adjustment, ensuring over 8 hours of operation during rainy days. Paired with a supercapacitor backup power supply, it guarantees stable performance in extreme weather conditions.

◎Extreme environment adaptability: Technologies such as UV-resistant lamp covers, electric heating films, and nano-hydrophobic coatings have been validated in the Qinghai-Tibet Plateau, coastal typhoon belts, and desert regions, extending the lifespan by three times compared to traditional street lights.

Quantity and Quality of Lamp Beads

1.Technological Breakthroughs in 300W High-Density Lamp Bead Array

Using 1,200 high-power LED chips (0.25W per chip), three-dimensional arrangement and liquid cooling heat dissipation achieve a luminous efficiency of 180lm/W, with three major performance leaps:

◎Luminous efficiency improvement: The overall luminous efficiency of the lamp reaches 180lm/W (industry average is 150lm/W), outputting 54,000 lumens at 300W power, with illuminance uniformity >0.7 (complying with CJJ45-2015 Urban Road Lighting Design Standard);

◎Heat dissipation revolution:Vacuum copper-plated substrate: Thermal conductivity >400W/(m·K), 3 times higher than aluminum substrates;

◎Microchannel liquid cooling technology: Built-in nanofluid circulation pipeline, thermal resistance <0.1℃/W, junction temperature stable below 65℃;

◎Intelligent temperature-controlled fan: Automatically starts when ambient temperature >40℃, noise <35dB (equivalent to library environment).

2.Lamp Bead Quality Control System

◎Incoming material inspection:

Spectral analyzer verifies wavelength consistency (±1nm);

High-low temperature impact test (-40℃ to 125℃, 100 cycles).

◎Production monitoring:

AOI automatic optical inspection identifies false solder joints;

Integrating sphere tests luminous flux of each lamp bead (error <3%).

◎Finished product verification:

Salt spray test (5% NaCl solution, no corrosion for 480 hours);

Vibration test (5-500Hz random vibration, no damage for 2 hours).

Monocrystalline Silicon Solar Panels

Analysis of Monocrystalline Silicon Technical Advantages

Adopting 210mm large-size monocrystalline silicon wafers (M12 specification) and PERC+SE technology, achieving four major performance breakthroughs:

◎Conversion efficiency: Laboratory efficiency exceeds 26.2% (mass-produced version reaches 23.5%), 25% higher than polycrystalline silicon;

◎Low-light response: Maintains 18% conversion efficiency under 200lux illuminance (polycrystalline silicon only 12%);

◎Temperature coefficient: Power attenuation rate -0.34%/℃ (polycrystalline silicon is -0.45%/℃), significant advantages in high-temperature environments;

◎Attenuation control: First-year attenuation <2%, 25-year linear attenuation <15% (complying with IEC 61215 standard).

 

Structural innovation

◎Bifacial power generation design: The back uses transparent conductive oxide (TCO) glass, which can absorb ground reflected light, with a comprehensive power generation gain of 8-25%;

◎Intelligent light tracking system: Through a dual-axis tracking bracket (optional), the solar panel is always perpendicular to the sun's rays, increasing daily power generation by 30-40%.
