Accurate Lighting Design with Dialux evo: Techniques & Tips

Lighting design is a critical aspect of creating functional and aesthetically pleasing spaces. Whether you're 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.

In this guide, we'll explore 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.

Advanced Features in DIALux evo 13

The latest version, DIALux evo 13, introduces several advanced features to enhance lighting design capabilities:

1. Obtrusive Light Calculation

DIALux evo 13 allows for the calculation of obtrusive light, ensuring that lighting installations comply with relevant standards and regulations. The software can compute various parameters, including:

• Luminous Intensity (I): The amount of light emitted in a particular direction.
• Proportionality Factor (ks): A measure of glare.
• Upward Flux Ratios (Ruf, Rul): The proportion of light emitted upwards.
• Glare Rating (RG): A quantitative measure of discomfort glare.

These calculations help designers minimize light pollution and ensure the comfort of occupants and the surrounding environment.

2. BIM Integration

DIALux evo 13 offers improved integration with Building Information Modeling (BIM) systems. The software can import and export BIM data, facilitating seamless collaboration between lighting designers and other stakeholders in the building design process.

3. Enhanced Visualization

The latest version enhances visualization capabilities, allowing designers to create realistic renderings of their lighting designs. This feature aids in presenting design concepts to clients and stakeholders effectively.

Best Practices for Lighting Design

To achieve optimal lighting design, consider the following best practices:

• Understand the Space Requirements: Assess the specific lighting needs of each area based on its function and usage patterns.
• Select Appropriate Luminaires: Choose luminaires that provide the desired light output and distribution.
• Ensure Uniform Lighting: Aim for uniform illuminance levels to avoid areas of excessive brightness or darkness.
• Consider Energy Efficiency: Select energy-efficient lighting solutions to reduce operational costs and environmental impact.
• Comply with Standards: Ensure that your lighting design meets local and international lighting standards and regulations.

Conclusion

DIALux evo is a powerful tool that empowers lighting designers to create effective and compliant lighting solutions. By understanding and utilizing its features, you can enhance the quality and efficiency of your lighting designs.
