1. Brightness Selection Standards
1. Illumination (Lux) Requirements
| Area Type | International Standard Illuminance Range | Uniformità (Uo) |
|---|---|---|
| Departure/Arrival Halls | 150-300 lx | ≥0,4 |
| Taxiway | 50-100 lx | ≥0.6 |
| Runway Edges | 20-50 lx | ≥0.7 |
| Stair/Step Areas | 200-300 lx | ≥0.5 |
| Baggage Sorting Area | 300-500 lx | ≥0.6 |
Basis: FAA AC 150/5345-7E and CIE 115:2010 recommendations, glare should be avoided (Threshold Increment TI ≤ 15%).
2. Luminous Flux (Lumens) and Luminous Efficiency
- Light Source Selection: LED fixtures with luminous efficacy ≥ 150 lm/W (solar systems should prioritize high efficiency with low consumption).
- Luminous Flux Calculation: Based on area size and target illuminance, formula: Total Lumens = Area (m²) × Target Illuminance (lx) ÷ Maintenance Factor (0.7-0.8).
2. Temperatura del colore e indice di resa cromatica
1. Color Temperature (CCT)
- Taxiway/Runway: 5000-6000K (cool white light with high contrast for obstacle recognition).
- Terminal Building Interior: 4000K neutral white (balancing comfort and visual clarity).
- Rest Areas/Passages: 3000K warm white light (reducing visual fatigue).
2. Indice di resa cromatica (CRI)
- Security Check Area/ID Verification Area: Ra ≥ 90 (accurately restoring color details).
- Other Areas: Ra ≥ 80 (meeting basic color rendering needs).
3. Pole Height and Material Design
1. Pole Height
| Area Width | Recommended Pole Height | Spaziatura di installazione |
|---|---|---|
| Taxiway (30-60m wide) | 12-18m | 30-50m (symmetrical lighting) |
| Terminal Perimeter Road | 8-12 mesi | 20-30m |
| Pedestrian Path/Stairs | 4-6 mesi | 10-15m |
2. Material Selection
- Pole: Hot-dip galvanized steel (corrosion resistant) or aluminum alloy (lightweight, wind load resistant ≥ 40m/s).
- Solar Bracket: Anodized aluminum + stainless steel bolts (suitable for high humidity environments).
4. System Design and Continuous Operation
1. Solar Power Supply System
- Continuous Lighting Days: At least 5 days (backup for rainy weather), equipped with lithium iron batteries (cycle life ≥ 5000 times).
- Component Power: Calculated based on daily charging efficiency ≥ 20%, formula: Solar Panel Power = Daily Consumption (kWh) ÷ (Peak Sunlight Hours × 0.8).
2. Intelligent Control Optimization
- Automatic Dimming: Through light sensors + microwave radar sensing, full power during peak human flow, reduced to 30% during idle periods.
- Monitoraggio remoto: Integrated KNX/EIB protocol (reference FAA case), supports fault alarm and energy consumption analysis.
5. Costo e ritorno sull'investimento (ROI)
| Progetto | Cost Composition | Periodo di ammortamento |
|---|---|---|
| Investimento iniziale | Fixtures + Poles + Solar System: $200-$400/set | 3-5 years |
| Operation and Maintenance Costs | Annual maintenance fee <$50/set (LED lifespan 100,000 hours) | |
| Energy-saving Benefits | 70%-90% energy savings compared to traditional grid systems |
Nota: According to IEA data, airport lighting accounts for 15%-20% of total energy consumption, and intelligent control can further reduce electricity costs by 30%.
6. System Optimization Recommendations
- Glare Prevention Design: Use cut-off fixtures (beam angle ≤ 60°) to avoid affecting pilots’ visibility.
- Redundant Configuration: Set up dual circuits for key areas (such as runways) to ensure system reliability.
- Maintenance Convenience: Modular fixture design that supports quick replacement (reference IEC TS 62100 cable standards).
