# Industrial Specification: Outdoor Solar Bollards

## 1. Technical Definition
Self-contained outdoor lighting fixtures powered by solar energy, designed for pathway, landscape, and architectural illumination.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-50°C ambient temperature, 0-100% relative humidity, 0-2000 m altitude**. Failure boundary: **Lithium-ion battery thermal runaway at 60°C cell temperature, PV panel efficiency drops below 5% at 85°C junction temperature, LED driver failure at 90°C junction temperature**, Mechanism: **Arrhenius equation degradation (10°C rule doubles failure rate), Shockley-Queisser limit (33.7% theoretical max PV efficiency), lithium-ion SEI layer decomposition at 60°C**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$  
> **Engineering Impact**: Governs heating element sizing for shrink tunnels/sealers.

- **Caution**: 
- **Caution**: 

### Q: What is the typical illumination duration for these solar bollards?
**A**: Our solar bollards provide 8-12 hours of illumination per full charge, depending on sunlight exposure and battery capacity settings.

### Q: Are these solar bollards suitable for all weather conditions?
**A**: Yes, with IP65 or higher IP rating, aluminum alloy housing, and polycarbonate components, they're designed to withstand rain, snow, and extreme temperatures.

### Q: How does the motion sensor feature work with solar power?
**A**: The motion sensor activates high-brightness mode when movement is detected, then returns to energy-saving mode, optimizing battery usage while providing security lighting.
