ReluxEmergencyCalc
The Emergency Distance Calculator – Building safety is no accident; it is the result of precise calculations. Our ReluxEmergencyCalc is a specialised API service that takes the complex task of safety lighting calculation out of the hands of architects, electrical planners, and especially manufacturers of emergency luminaires.
Two Modes – One Solution
Supports either the EN 1838:2018 or EN 1838:2024 standard
Escape Route Mode
Perfect for corridors and rescue paths. The tool calculates optimal spacing in axial and transverse directions
Area Lighting
For anti-panic lighting. The tool calculates optimal spacing in axial and transverse directions
Intelligent Technology, Easy to Use
1. Upload Data: Send the light distribution curve of your luminaire (LDT file as Base64) to the service.
2. Set Parameters: Define mounting heights (e.g., 2.5 m to 20 m) and maintenance factors (e.g., 0.8).
3. Receive Results: Within seconds, the API delivers exact distance data in JSON format:
- Distance from luminaire to luminaire (Axial and Transverse)
- Distance from luminaire to wall (Axial and Transverse)
