# Industrial Specification: Solar Table Lamps

## 1. Technical Definition
Portable lighting devices that convert solar energy into electrical power to illuminate indoor or outdoor table surfaces.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-5.0 lux (illuminance at 1 meter distance)**. Failure boundary: **Solar irradiance below 100 W/m² for 72 consecutive hours**, Mechanism: **Photovoltaic cell bandgap energy (1.1 eV for crystalline silicon) insufficient to overcome diode forward voltage drop (0.6-0.7 V) at low photon flux density**.

### 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.

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: How long does the solar table lamp take to fully charge?
**A**: Charging time varies by solar panel wattage and sunlight conditions, typically ranging from 6-10 hours under direct sunlight for a complete charge.

### Q: What is the average runtime on a full battery charge?
**A**: Runtime depends on battery capacity (mAh) and light output settings, but most models provide 8-12 hours of illumination at medium brightness.

### Q: Can these solar table lamps be used indoors without sunlight?
**A**: Yes, they can be charged via USB as a backup, and the light sensor automatically adjusts brightness based on ambient light conditions for optimal indoor use.
