Based on technical academic and professional documentation, "DIALux 314" typically refers to the EET 314: Lighting Design Technology
course, which uses DIALux software for complex lighting simulations and technical reporting.
Below is a structured "solid paper" overview covering the technical implementation and calculation methodologies relevant to this specific level of lighting design.
Technical Overview: Lighting Design and Simulation in DIALux Objective:
To design and validate energy-efficient lighting systems that meet international standards (such as EN 12464-1 ) using computer-aided 3D simulation. ResearchGate 1. Geometric Modeling and Environment Setup
The first stage involves constructing a precise 3D model of the interior or exterior space. Geometry Definition:
Designers input room dimensions (length, width, height) and incorporate architectural elements like windows and doors. Surface Reflectance: Accurate simulation requires assigning reflectance values ( ) to surfaces (walls, floors, ceilings). Standard values: Ceiling (0.7), Walls (0.5), Floor (0.2). Furnishing Influence:
Adding 3D objects (desks, cabinets) is critical as they create shadows and influence the overall uniformity of light ( cap U sub 0 ResearchGate 2. Luminaire Selection and Photometric Data
Lighting quality is determined by the "photometric file" associated with specific luminaires. IES/LDT Files:
These digital files contain the luminous intensity distribution of a lamp. Dialux uses this data to calculate how light spreads across the space. Light Loss Factor (LLF):
A maintenance factor (usually 0.8) is applied to account for the depreciation of lamp output and dirt accumulation over time. 3. Calculation and Analysis Methodologies dialux 314
DIALux performs complex radiosity or ray-tracing calculations to provide precise metrics. IntechOpen Illuminance ( Measured in , this defines the amount of light falling on a work plane. Uniformity ( cap U sub 0 The ratio of minimum illuminance to average illuminance ( ). A higher ratio (e.g., is greater than 0.40 ) ensures visual comfort and reduces eye strain. Unified Glare Rating (UGR):
A metric used to predict the psychological discomfort caused by luminaires in the field of view. ResearchGate 4. Comparative Analysis: Manual vs. Software
Professional reports often compare software results with the Lumen Method manual calculation:
cap N equals the fraction with numerator cap E cross cap A and denominator cap phi cross n cross cap C cap U cross cap L cap L cap F end-fraction : Number of luminaires. : Target illuminance. : Luminous flux per lamp. cap C cap U : Coefficient of Utilization.
While manual methods provide a baseline, DIALux is preferred because it accounts for complex room shapes and object reflections that manual formulas cannot capture. ResearchGate Conclusion
While there is no specific industry document titled "Dialux 314," the number commonly appears in the DIALux evo
community as a specific case study or tutorial step, most notably in tutorials for creating curtains and complex lighting concepts
Below is a "useful story" or workflow based on these common DIALux teaching modules, specifically focusing on the advanced "Case Study 31" (often mistyped as 314) and the process of building stories in professional lighting design. The Lighting Designer’s Challenge: A Case Study
Imagine you are tasked with designing the lighting for a modern office building. You aren't just placing lights; you are creating an environment that balances productivity with aesthetic comfort. 1. Building the Story (Literally)
Before the light hits the floor, you must build the "story" (floor) of the building. In DIALux evo, this involves: Importing Plans If you meant DIALux evo 14 (newer, BIM-based)
: Bringing in CAD floor plans to trace the building's outline. Creating New Storeys
: Navigating to "Story and Building Construction" to add levels. A new story often starts with the same footprint as the floor below, which you then modify by adding points
to adjust the shape for balcony overhangs or tiered designs. 2. Mastering the Details (The "314" Connection) Advanced users often look for specific tutorials like "Case Study 31: Creating a Curtain" to add realism to their simulations. Curtains and Daylight
: Adding textures like curtains isn't just for looks; it significantly affects how daylight is calculated within the room. Uniformity Check
: A critical part of the "story" is ensuring the light is evenly distributed. Designers use DIALux to calculate the uniformity ratio
(minimum vs. average illuminance) to prevent harsh shadows or "hot spots" that cause eye strain. 3. The Final Presentation
Once the simulation is complete, the story moves to the client. Using DIALux Pro Features , designers can: Export to PowerPoint/Word
: Skip the manual paperwork and generate high-quality presentations for quotations. Raytracing
: Create photorealistic images that show the client exactly how the light will bounce off the furniture and walls. Key Learning Resources

4 Dialux evo for beginners: Create a new storey for the first floor
Main features difference:
If you are determined to try the classic software, you can often find legacy versions on the official DIAL website in their "Downloads" archive or through lighting manufacturer websites.
However, if you are looking for the 3.14 version number specifically, you won't find it because it doesn't exist! The jump from DIALux 3.0 went straight to DIALux 4.0.
Strictly speaking, there is no official “DIALux 314” release. The number refers to the final stable builds of DIALux version 3.14 (part of the classic DIALux 3 series). Released over a decade ago, this version represented the peak of the “old school” DIALux—before the complete architectural overhaul that became DIALux evo.
While DIALux evo focuses on 3D building modeling, intuitive terrain, and real-time visualization, DIALux 3.14 was a number-crunching beast. It looked like a spreadsheet married a CAD program, and it was glorious.
One of the most celebrated updates in Dialux 314 is the Plugfinder function. This tool automatically detects the driver and control gear of DALI systems. Instead of manually inputting 20 parameters for each luminaire, Dialux 314 reads the device's electronic signature.
You might be asking: Should I just stick with DIALux 4.13?
The honest answer is mostly no, but partly yes.
