# How to Use Laser for Accurate Aiming and Focusing on Sports Fields with DIALux
## 🎯 Laser Aiming in Sports Lighting: A Quick Overview
Laser aiming is the **top choice** for precisely positioning LED sports lighting. It guarantees accurate light distribution and uniform coverage across playing fields.
## 🔧 Must-Have Equipment
- Laser pointer (300m+ range)
- DIALux-generated X,Y coordinates
- Torque wrench & socket wrenches (for fixture setup)
## 📐 DIALux Design Steps
1. **Set up coordinates**: Origin (0,0,0) at center; X (length), Y (width), Z (height) axes.
2. **Calculate aiming points**: Based on fixture position, beam angles, lux levels, uniformity (U1/U2), and glare limits (<60°).
## 🎯 Laser Aiming Methods
### Method 1: Coordinate-Based (Recommended)
1. Mount laser to fixture via aiming mount (no wobble!).
2. Loosen fixture hardware for adjustability.
3. Aim laser at DIALux coordinates; tweak fixture until spot hits target.
4. Tighten hardware, recheck alignment.
### Method 2: Orient-Tilt (Alternative)
- Adjust via Z-plane (orient) and Y-plane (tilt) angles.
- Less precise due to installation variables.
## 📊 Why DIALux Integration Matters
- Delivers exact aiming coordinates and optimal beam angles.
- Recommends mounting heights (70-100ft) and pole positions.
- Features: Sports templates, photometric tools, 3D visuals, compliance checks (FIFA/UEFA), and aiming ray exports.
## ⚡ Key Specs
- **Laser**: 300m+ range, daylight-visible green, <5mm deviation at 100m.
- **Sports Standards** (example):
| Application|Avg Lux |Uniformity (U1/U2) | Beam Angles |
|----------------|---------|---------------------|-------------|
| FIFA Grade 1 | 750+ | 0.4/0.6+ | 12°-60° |
| FIFA Grade 2 | 500+ | 0.4/0.6+ | 15°-45° |
| FIFA Grade 3 | 300+ | 0.4/0.6+ | 20°-60° |
## 🔍 Success Tips
- **Accuracy**: ±2° max deviation; coordinates within 0.5m of target.
- **Challenges**: Watch for pole/ground variations, wind, and daylight laser visibility.
## 🛠️ Best Practices
- **Pre-install**: Verify DIALux design; test lasers.
- **During install**: Use calibrated lasers; work systematically; double-check.
- **Post-install**: Verify with light meters; document final coordinates.
## 📈 Quality Results
Laser + DIALux = ±5% illuminance accuracy, on-spec uniformity, 60-80% faster commissioning, and fewer adjustments. Perfect for pro-level play, spectators, and broadcasts!
