Dialux 314 Verified

While there is no famous novel or movie titled " DIALux 314 ," the name refers to a technical context within the field of lighting design technology

Specifically, "314" is most likely the course or module code for EET 314: Lighting Design Technology Centennial College . In this academic "story," students use the DIALux evo software to master the art and science of illumination. The "Story" of a DIALux 314 Project

For a student or professional in this module, the narrative of a project typically follows these stages: The Blueprint

: The story begins by importing a 2D CAD floor plan or an IFC file into the DIALux software environment. Constructing the World

: The designer traces the building's perimeter and sets the "story height"—often 10 feet for a standard office—before "cutting out" spaces for windows and doors. Setting the Standards

: The goal is usually defined by a target illuminance (e.g., 60 foot-candles or specific lux levels) to ensure the space is functional and safe. The Luminaire Selection

: The designer imports specific "IES files" (digital profiles of real light fixtures) from manufacturers and arranges them in polygonal or grid patterns. The Calculation Phase

: The software runs complex simulations to determine if the design meets uniformity and lighting standards. If a "red square" appears in the results, it indicates the standard hasn't been met, and the design must be tweaked. The Final Report

I’m not sure what you mean by “dialux 314: give me a complete piece.” I’ll assume you want a complete Dialux lighting project file description (room, fixtures, calculations, and export-ready settings) for a typical scenario. I’ll produce a ready-to-implement Dialux project specification you can recreate in DIALux evo (including geometry, luminaire choices with photometric assumptions, calculation grids, target illuminances, and export notes). If you meant something else (a file, a code snippet, or a specific standard), tell me and I’ll adjust.

Project: Office open-plan — 8 × 12 m, single zone, 2.8 m height, suspended ceiling, UGR <= 19, maintained illuminance 500 lx on desks. dialux 314

1. Room geometry

• Room size: length 12.00 m × width 8.00 m × room height 2.80 m.
• Workplane height: 0.75 m.
• Floor reflectance: 20% (0.20).
• Wall reflectance: 50% (0.50).
• Ceiling reflectance: 70% (0.70).
• Obstructions: none.

2. Lighting concept

• Continuous recessed modular LED luminaires with asymmetric distribution for uniformity and UGR control.
• Target maintained illuminance on workplane: 500 lx.
• Maximum UGR: 19.
• Uniformity (Emin/Eavg) target: ≥ 0.6.
• Color temperature: 4000 K.
• CRI: ≥ 80.
• Lumen maintenance factor (LMF): 0.8 (includes dirt and LED depreciation).
• Room maintenance factor included: 0.9 (if separate, multiply with LMF).

3. Recommended luminaire (spec for modeling)

• Type: 600 × 600 mm recessed LED panel, microprismatic diffuser, asymmetric optics.
• Rated luminous flux: 4200 lm (source flux).
• Useful luminous flux (after driver and optic losses): 3600 lm.
• Luminous efficacy: ~120 lm/W (approx).
• Photometric file: IES/IESNA or Eulumdat file from manufacturer.
• Dimming: DALI (set scene and presence detection later).

4. Mounting and layout

• Mounting height: ceiling recessed so optical center at 2.8 m.
• Grid layout: 3 rows × 4 columns = 12 luminaires.
• Spacing: along length (12 m): 3 luminaires spaced at 3 m centers (3 × 3 m = 9 m) with 1.5 m end spacing each side; along width (8 m): 4 luminaires spaced at 2 m centers (4 × 2 m = 8 m) centered.
• Alternative spacing for tighter uniformity: 4 × 4 array (16 luminaires) at 2.4 m × 2.0 m spacing.

5. Calculation setup in DIALux

• Create new room with given geometry and reflectances.
• Import luminaire photometric IES/ldt.
• Place 12 luminaires per grid above.
• Set calculation grid: step 0.5 m, workplane height 0.75 m, perimeter offset 0.5 m.
• Set maintenance factor: overall = 0.72 (0.9 room × 0.8 LMF) or enter LMF and room separately if DIALux allows.
• Set glare calculation: UGR, input luminaire dimensions and diffuser type so DIALux calculates UGR.
• Run calculations for average illuminance, minimum, uniformity, and UGR.

6. Expected results (approximate, for 12 luminaires each 3600 lm useful)

• Total useful lumens in room: 12 × 3600 = 43,200 lm.
• Area: 96 m² → average theoretical lux (no losses) = 43,200 / 96 = 450 lx before maintenance.
• After maintenance factor 0.72 → maintained average ≈ 324 lx (below 500 lx) — so increase luminaire output or add more fixtures.
• With 16 luminaires: total useful lumens = 57,600 lm → before maintenance = 600 lx → maintained ≈ 432 lx (still below 500 lx).
• Therefore recommend either higher-output luminaires (~5200 lm useful) with 12 units, or use 18 units of 3600 lm (18×3600=64,800 → maintained ≈ 486 lx — near target). Best: 16 luminaires of 4500 lm useful → maintained ≈ 540 lx.

7. Final recommended configuration (practical)

• Use 16 recessed panels (4 × 4 layout), each useful flux 4,500 lm (manufacturer model: e.g., "PanelX 600/600 4500 lm 4000K UGR<19" — pick matching IES).
• Spacing: 2.4 m × 2.0 m as above.
• Calculation grid: 0.5 m; MF = 0.72.
• Expected maintained average: ~540 lx; uniformity ≥0.6; UGR <19 (verify with photometry).
• Controls: DALI + presence sensors + daylight dimming to reduce energy.

8. DIALux export and deliverables

• Export formats: DWG for layout, IES export not needed, and DIALux project file (.evo) to share.
• Include following outputs in final deliverable: plan view with luminaire positions, isolux plot, UGR map, luminance rendering, calculation report (average, min, uniformity, UGR), energy report (annual consumption estimated from operating hours).
• Suggested operating hours: 2,200 h/year (office) — calculate annual energy: 16 × (4500 lm /120 lm/W ≈ 37.5 W) ≈ 600 W total → annual = 600 W × 2,200 h = 1,320 kWh.

9. Steps to implement in DIALux evo (concise)

1. New project → Room → set dimensions and reflectances.
2. Import manufacturer IES file or create luminaire with given flux and distribution.
3. Place luminaires in 4×4 grid; set mount height.
4. Set workplane 0.75 m, grid 0.5 m, maintenance factor 0.72.
5. Run calculation; check avg lux, uniformity, UGR.
6. Adjust luminaire count/output until targets met.
7. Add controls, save .evo, export PDF calculation report and DWG layout.

If you want, I can:

• Produce a ready-to-import DIALux .ldt/.ies stub (text) for a sample luminaire (you’d still adjust manufacturer values).
• Or generate exact fixture counts and spacing for a different target (e.g., 300 lx, 750 lx), different room sizes, or supply a catalog recommendation.

Which follow-up would you like: (A) IES/IES stub for the sample panel, (B) exact layout for a different target illuminance, or (C) a simplified file-ready step sequence to paste into DIALux? Also tell me if the room dimensions or target lux differ.

Although 3.14 was a foundational version, the core principles of DIALux remain consistent across iterations: Product data sheet - DIALux Luminaire Finder While there is no famous novel or movie

However, "314" likely refers to one of three things: a specific paint colour from Dulux, a polishing compound, or a specific manual page for the DIALux software. 1. Dulux 314: Blue Haven (Paint)

If you are looking for a review of a specific aesthetic, "314" is the code for Dulux Blue Haven.

Aesthetic & Use: This is a soft, refreshing blue-green shade with a Light Reflectance Value (LRV) of 73.70, making it highly reflective and ideal for brightening interior spaces.

Performance: It is frequently used for interior walls in matte or eggshell finishes. Reviews from MyPerfectColor suggest it provides a professional, smooth finish suitable for both residential and commercial applications. Technical Specs: HEX Code: #C5E5E2. RGB Values: 197, 229, 226. 2. Dialux Polishing Compounds

"Dialux" is also a brand of high-end polishing compounds used in jewelry and metalwork.

Quality: These compounds are manufactured in Europe under strict quality controls and are prized for adhering exceptionally well to buffs and brushes, meaning very little product is needed to achieve a high shine.

Specific Types: While the brand is famous for its color-coded bars (like Blue, Red, and Green), it is often used for the final high-polish of soft metals like silver and gold. 3. DIALux Software (Page 314)

In technical manuals for DIALux lighting software, page 314 specifically covers Raytracing and POV-Ray configurations.

Functionality: This section explains how to generate photorealistic images by calculating indirect light and image settings. Room geometry

Software Context: The current industry standard is DIALux evo 13, which allows for 3D visualization and calculation of indoor and outdoor lighting. It is widely used by over 750,000 professionals to ensure compliance with standards like EN 12464.

Is It Worth Using Today?

You might be asking: Should I just stick with DIALux 4.13?

The honest answer is mostly no, but partly yes.

Why you shouldn't use it:

• Standards: Lighting standards (like EN 12464) have updated. Older versions of the software calculate according to older maintenance factors and grid definitions.
• Compatibility: Exporting to modern CAD files (like Revit or newer AutoCAD DWG formats) is much harder in legacy software.
• Support: DIAL no longer updates version 4.13. If a Windows 11 update breaks it, it stays broken.

Why you SHOULD use it:

• Retro-computing: If you have an old laptop and need to do a quick lumen method check, nothing beats the speed of the classic interface.
• Mental Models: If you are an engineer who just wants to know "How many fittings do I need for 500 lux?", the older interface aligns better with that mental math than the complex modeling of modern evo.

Known Issues and Workarounds (Dialux 314 Bugs)

No major release is perfect. Based on community feedback from the "Lighting Designers Global" forum (January 2026), here are the current bugs associated with Dialux 314:

Issue 1: Intel Arc GPU Glitches Users with Intel Arc graphics cards (A770, A750) report flickering textures in OpenGL mode.

• Workaround: Go to Settings > Visualization > Force "DirectX 11" mode instead of "Auto."

Issue 2: DWG Import Scale Factor If you import an AutoCAD drawing created in Imperial units (feet/inches) into a Metric project, Dialux 314 sometimes fails to auto-detect units.

• Workaround: Before importing, open the DWG in a text editor or use the _DWGCONVERT command in AutoCAD to strip unit metadata.

Issue 3: MacOS Virtual Machine Crash Dialux does not natively run on MacOS. Under Parallels Desktop 19, version 4.13 crashes when exporting PDFs.

• Workaround: Export to DIALux 3D XML first, then open on a Windows machine for final PDF generation.
