70W Semi-Integrated Solar Street Light** shown in the generated image above:
## Key Components & Design
* **Top-Mounted Solar Panel:**
* Features an independent monocrystalline/polycrystalline panel fixed at the top of the pole.
* Designed to be manually adjusted/tilted toward direct sunlight for maximum energy absorption regardless of pole orientation.
* **Integrated LED Luminaire:**
* Houses the **70W high-brightness LED array**, built-in **\text{LiFePO}_4 battery**, and intelligent **MPPT/PWM charge controller** inside a single weatherproof casing.
* Extends on a side-arm bracket to cast even illumination over streets and pathways.
* **Mounting Structure:**
* Heavy-duty steel pole with anticorrosive powder coating designed for wind resistance and outdoor durability.
## Detailed Specifications
| Feature | Specification |
|---|---|
| **LED Power** | 70W High-Lumen Chip Array |
| **Luminous Efficacy** | \sim 130 - 150 \text{ lm/W} (\approx 9,000 - 10,500 \text{ Lumens}) |
| **Solar Panel Rating** | 100W – 160W Mono/Poly Panel |
| **Battery Type** | Lithium Iron Phosphate (\text{LiFePO}_4), 12.8V / 40–50Ah |
| **Charging Time** | 6 to 8 hours under direct sunlight |
| **Backup / Runtime** | 12+ hours continuous per night (supports 2–3 rainy days) |
| **Operating Modes** | Dusk-to-Dawn, Motion Sensor (PIR), or Dimming Timers |
| **Protection Standard** | IP65 / IP66 Waterproof & Dustproof |
| **Recommended Height** | 6m to 8m pole height |
## Advantages of Semi-Integrated Systems
1. **Optimal Sunlight Exposure:** Unlike fully integrated ("All-in-One") lights where the solar panel is fixed horizontally on top of the fixture, semi-integrated units allow the panel to be rotated freely toward the sun.
2. **Heat Isolation:** Keeping the battery integrated inside the luminaire casing while the solar panel sits above prevents the heat absorbed by the solar panel from overheating the battery, extending battery lifespan.
3. **Easy Maintenance:** Components like the battery, controller, or light head can be serviced without disturbing the solar panel mount.
