Product Introduction
◎Lamp pole anti-corrosion: Adopting a triple anti-corrosion system of "hot-dip galvanizing + powder coating + cathodic protection" and Q345B high-strength alloy base material, it achieves an anti-corrosion life of more than 20 years. Through IP68 sealing and modular design, it balances weather resistance and maintenance convenience.
◎Outdoor adaptation: With IP65 waterproof and dustproof performance, wide-temperature components (-40℃ to +70℃), 12-level wind-resistant structure and lightning protection design, it meets the needs of extreme environments such as extreme cold, high temperature, typhoons, and high salt spray.
◎Intelligent control: Equipped with an MPPT microcomputer controller, it realizes 99% charging efficiency, three-stage intelligent charging management, light-sensing adaptive dimming, and fault self-diagnosis, reducing operation and maintenance costs and extending battery life by 3 times.
High-Strength Anti-Corrosion Lamp Pole
As the supporting structure of street lights, lamp poles must withstand long-term natural challenges such as wind, sun exposure, rain erosion, and salt spray corrosion. The 90W Solar Street Light adopts a triple anti-corrosion system of "hot-dip galvanizing + powder coating + cathodic protection" combined with high-strength alloy materials to achieve an anti-corrosion life of more than 20 years.
Advanced Alloy Base Material: Dual Protection of Impact Resistance and Fatigue Resistance
The main body of the lamp pole is made of Q345B low-alloy high-strength structural steel, with a yield strength of 345MPa, 1.5 times that of ordinary Q235 steel.
◎Impact resistance: Maintains good toughness at -20℃, capable of resisting impacts from hailstones and flying stones (tested to withstand a 5kg weight falling from a 3-meter height without deformation);
◎Fatigue resistance: After 100,000 bending tests (simulating 10 years of wind sway), the residual deformation is less than 0.2%, ensuring no loosening during long-term use;
◎Lightweight design: Under the same strength, the pole weight is 20% lighter than traditional steel, reducing transportation and installation costs.
Triple Dynamic Anti-Corrosion Process
◎First Layer: Hot-Dip Galvanized Anti-Corrosion Layer
The entire lamp pole is immersed in 550℃ molten zinc solution to form a zinc-iron alloy layer with a thickness ≥85μm.
360° all-round coverage: Including hidden parts such as inner walls, flanges, and weld seams;
Sacrificial anode protection: The zinc layer corrodes first, protecting the base material from damage (anti-corrosion life up to 15 years);
Salt spray resistance test: Passed 1000-hour neutral salt spray test (ISO 9227 standard) with no red rust on the surface.
◎Second Layer: Outdoor-Grade Powder Coating
A polyester powder coating is sprayed on the galvanized layer, forming a 0.1mm dense coating after curing at 200℃.
UV aging resistance: Using imported light stabilizers, the color difference ΔE is <3 after 5 years of outdoor use (imperceptible to the naked eye);
Chemical corrosion resistance: Resists erosion from acid rain, bird droppings, and cleaning agents;
Self-healing function: Minor scratches can automatically close through thermal expansion and contraction, preventing penetration of corrosive media.
◎Third Layer: Cathodic Protection Enhancement
A magnesium alloy sacrificial anode block is embedded at the bottom of the lamp pole, which continuously absorbs surrounding corrosion current through electrochemical principles, especially suitable for coastal high-salt-spray areas. Test data shows that this design extends the lamp pole's life to 25 years in marine climates.

Intelligent Microcomputer Controller
Equipped with an MPPT microcomputer controller, it maximizes energy utilization efficiency and minimizes operation and maintenance costs through functions such as three-stage charging algorithm, light-sensing adaptive dimming, and fault self-diagnosis.
MPPT Charging Technology: 30% Higher Power Generation Efficiency
The controller adopts Maximum Power Point Tracking (MPPT) algorithm, which real-time monitors the voltage and current of the solar panel and dynamically adjusts charging parameters to ensure:
◎Charging efficiency: Up to 99% (traditional PWM controllers only 75-80%);
◎Low-light startup: Can start charging under 500lux illumination (traditional solutions require 1000lux);
◎Fast charging: 80% battery capacity in 3 hours.
Test data shows that under the same sunlight conditions, the daily power generation of this product is 28% higher than traditional solutions.
Light-Sensing Adaptive Dimming: On-Demand Energy Allocation
The controller has a built-in high-precision photosensitive sensor, which can automatically adjust LED brightness according to ambient light:
◎Late-night mode (0:00-5:00): 30% brightness to meet basic lighting needs;
◎Early-morning mode (5:00-7:00): 70% brightness, suitable for morning exercise and commuting;
◎Full-bright mode (18:00-23:00): 100% brightness to ensure safety during peak hours.
