120W Solar street light

Key features:

• Medium-to-High Power Output (120W): The “120W” generally refers to the high lumen output or equivalent incandescent wattage, indicating that it provides significant brightness. Utilizing modern LED technology, it achieves this powerful illumination with efficient actual energy consumption, making it suitable for areas requiring substantial lighting without being excessively bright for residential zones.
• LED Technology: It employs energy-efficient LED (Light Emitting Diode) chips (e.g., SMD 2835, 5730, or 3030 series) which offer:
  • Long Lifespan: Typically exceeding 50,000 hours, significantly reducing maintenance and replacement costs.
  • High Efficiency: Producing more light per watt compared to traditional lighting.
  • Optimal Light Quality: Usually emitting a cool white light (around 6000K-6500K) that enhances visibility and security.
• Integrated Solar Design: This is an “all-in-one” or “integrated” unit. All necessary components—the solar panel, LED lamp, rechargeable battery, and smart charge controller—are neatly housed within a single, streamlined fixture. This design simplifies installation, as there’s no need for complex wiring to the grid or separate component mounting.
• Aluminium Casing: The use of an aluminium casing is a crucial design choice that offers several benefits:
  • Superior Heat Dissipation: Aluminium is an excellent thermal conductor, effectively dissipating the heat generated by the LEDs. This is vital for maintaining LED efficiency and extending their operational life.
  • Exceptional Durability & Corrosion Resistance: Aluminium is inherently resistant to rust and corrosion, making the light highly durable in various outdoor weather conditions, including rain, high humidity, and extreme temperatures, ensuring long-term performance.
  • Robust yet Lightweight: It provides a strong protective enclosure while being relatively light, which eases installation and reduces the structural load on mounting poles.
  • Modern Aesthetic: Contributes to a clean, contemporary, and professional appearance.
• Efficient Power Storage:
  • Solar Panel: Equipped with a high-efficiency monocrystalline or polycrystalline silicon solar panel designed to capture maximum sunlight and convert it into electrical energy.
  • Battery: Stores the generated electricity. Modern 120W units commonly utilize LiFePO4 (Lithium Iron Phosphate) batteries (e.g., 3.2V or 6.4V systems with capacities ranging from 15AH to 30AH). LiFePO4 is favored for its long cycle life, thermal stability, and consistent performance across varying temperatures, which are critical for reliable street lighting.
• Intelligent Control System:
  • Dusk-to-Dawn Operation: An integrated photosensor automatically turns the light on when it gets dark and off at sunrise.
  • Motion Sensor: Many models include a PIR (Passive Infrared) or microwave radar sensor. This allows the light to operate at a lower, power-saving dim level when no activity is detected, and then switch to full brightness when motion is sensed, optimizing battery usage and extending autonomy.
  • Remote Control: Often provided for convenient adjustment of operating modes, brightness levels, and timing programs.
• High IP Rating: Typically boasts an IP65 or IP66 rating, signifying robust protection against dust ingress and resistance to water jets, making it well-suited for exposed outdoor installation.
• Installation: Recommended mounting height generally ranges from 4 to 8 meters, depending on the desired spread and intensity of illumination.
• Long Autonomy: Designed to provide continuous lighting for several nights (e.g., 1-3 rainy days or 10-20 hours) on a single full charge, even during periods of limited sunlight.
