A Practical Decision Framework (Structure, Glare, Maintenance)

Most control complaints are not about lux—they’re about how lighting changes. Specify curve and transition behavior, then verify it with a simple commissioning record.

Réponse : Avoid complaints by defining scene levels + transition times and choosing a dimming curve that matches human perception (often smoother than pure linear output).
Make it verifiable with a scene table, parameter sheet, and transition test log inside the sign-off pack.

Dans les cas suivants

Use this guide when your project includes multiple scenes (match/training/curfew) and you want transitions to feel smooth and predictable.

Typical scenarios

Multi-scene venues: frequent changes increase complaint risk.
Broadcast venues: transitions must not distract cameras.
Multi-scene controls: commissioning records are essential.
Retrofits: controls may be upgraded separately from luminaires.

Exigences clés / indicateurs clés

Use these metrics to specify and verify transitions like an engineer (not a subjective debate).

Metric	Quelles sont les conséquences ?	Pourquoi est-ce important ?	How to verify
Scene levels	Operating intent.	Defines what modes exist.	Scene table with target %.
Fade/transition time	Visual comfort.	Too fast = stepping complaints.	Parameter record + test log.
Dimming curve	Perceived smoothness.	Linear output may feel non-linear.	Curve type documented + on-site observation.
Minimum dim level	Stability.	Too low can expose driver limits.	Parameter sheet + scene verification.
Records	Repeatability	Stops “it changed later” disputes.	Sign-off pack logs.

Definitions

Dimming curve defines how control input relates to light output. Because perception is non-linear, a perceptual/log curve often feels smoother than strictly linear output.

Typical target ranges

Targets depend on venue preference. Practical approach:

Define scenes and acceptable transition behavior.
Choose a curve and verify transitions in real conditions.
Record settings in the handover pack.

Déroulement étape par étape

Engineering diagram (workflow).

Workflow: define tier → map constraints → test 4/6/8 pole options in calculation → choose option with best risk profile → lock aiming limits and sign-off deliverables.

Inputs to collect

Scene definitions and operating schedule.
Control system type and controller capabilities.
Any broadcast/user comfort constraints.

Design decisions

Select dimming curve type and default fade times.
Define minimum dim limits and acceptance notes.
Define commissioning tests and record format.

Verification & sign-off

Scene table + parameter sheet.
Transition test log with observations.

Erreurs courantes

No documented curve or fade settings.
Transitions tested only once (not in real use)
Minimum dim too low causing artifacts.
No sign-off records—settings drift later.

FAQ

Do different dimming curves affect perceived brightness?

Yes. Human perception is non-linear, so curve choice changes how ‘smooth’ transitions feel.

Will fast transitions cause complaints?

They can—especially if people notice stepping, flicker, or sudden glare changes.

How do I specify scene transitions in a tender?

Define scenes, transition times, and verification method; require commissioning tests and records.

Is linear dimming always best?

Not necessarily. Linear output doesn’t always feel linear; many venues prefer perceptual/log curves.

What should be in the sign-off record?

Scene table, transition settings, and a test log with observations and any deviations.
