Lighting design is a critical aspect of creating functional and aesthetically pleasing spaces. Whether you are designing for residential, commercial or industrial environments, achieving optimal lighting requires precise planning and calculation. One of the most powerful tools available for this purpose is DIALux evo, a professional lighting design software that allows designers to plan, calculate and visualize light for indoor and outdoor areas.
This guide explores how to effectively use DIALux evo for lighting design and lux calculation, ensuring your projects meet both functional and regulatory requirements.
What Is DIALux Evo
DIALux evo is a free professional lighting design software used by engineers, electricians and lighting designers worldwide. It enables users to plan, calculate and visualize lighting for various environments, from entire buildings to individual rooms, car parks and street lighting. With real luminaires from over 390 renowned manufacturers, DIALux evo offers a comprehensive platform for lighting design.
Getting Started With DIALux Evo
1. Installation and Setup
Download and install the latest version of DIALux evo from the official website. The software is available in multiple languages and is compatible with various operating systems. Once installed, launch the application and set up your workspace according to your project requirements.
2. Creating a New Project
Start a new project by selecting the appropriate template based on your design needs. DIALux evo offers templates for different types of spaces, including offices, classrooms and outdoor areas. Customize the layout by adding walls, windows and other architectural elements to match the real-world dimensions of your project.
3. Importing CAD and BIM Data
For complex projects, DIALux evo supports the import of CAD and BIM data, allowing you to integrate architectural models directly into your lighting design. This feature enhances accuracy and streamlines the design process.
Understanding Lux Calculation
Lux is the unit of illuminance, measuring the amount of light that falls on a given surface area. Accurate lux calculation is crucial to ensure that spaces are adequately lit and comply with lighting standards.
1. Illuminance Calculation Methods
DIALux evo provides several methods for calculating illuminance.
- Lumen method: calculates the average illuminance on a workplane based on the total luminous flux emitted by the luminaires and the room's dimensions
- Point-by-point method: determines the illuminance at specific points within a space, offering detailed analysis for critical areas
- Ray tracing method: simulates the path of light rays to calculate illuminance, accounting for reflections and surface properties
2. Factors Affecting Illuminance
Several factors influence illuminance levels.
- Luminous flux: the total amount of light emitted by a light source
- Room geometry: the dimensions and layout of the space
- Reflectance: the ability of surfaces to reflect light
- Luminaires' positioning: the placement and orientation of light fixtures
3. Maintenance Factor and Design Factor
To account for the gradual decrease in illuminance over time due to lamp aging and dirt accumulation, DIALux evo incorporates maintenance and design factors.
- Maintenance factor: represents the expected decrease in illuminance over time
- Design factor: adjusts the initial illuminance to compensate for future losses
