Technical meaning
- A dimmer is a lighting control device that changes light output when the connected load and control method are compatible.
- Dimming terms can describe phase-cut, 0-10 V, DALI or other control approaches, each with different compatibility requirements.
Calculation use
- Dimmer notes help note whether a lighting estimate assumes fixed output or controlled output.
- Driver and strip load calculations can include a dimming compatibility note without turning the calculation into wiring advice.
Not the same as
- A dimmer is not universally compatible with every LED lamp, driver or load size.
- A dimmer note is not an instruction to connect controls or alter wiring.
Australian context
- Australian lighting notes should name the dimming method as a compatibility item and keep any electrical work outside the public calculation.
Examples
| Example | Value | Planning note |
|---|
| Phase-cut | Leading or trailing edge | Often discussed in retrofit contexts, but compatibility depends on the load and driver. |
|---|
| 0-10 V | Control signal | A separate control method that should be matched with compatible control gear. |
|---|
| DALI | Digital control | A control ecosystem term, not a simple brightness or wattage value. |
