Technical meaning
- An LED driver supplies the electrical output form that a compatible LED load needs, such as constant voltage or constant current.
- Driver ratings usually include output voltage or current, rated power, load range and sometimes dimming or control method.
Calculation use
- LED strip driver estimates compare connected load with rated capacity before adding a headroom allowance.
- Driver notes help separate load sizing from dimming compatibility, voltage drop, heat, enclosure and licensed electrical checks.
Not the same as
- An LED driver is not chosen by wattage alone; output type, rating range and compatibility still matter.
- A driver sizing estimate is not a wiring direction and does not settle installation, enclosure or protection requirements.
Australian context
- Australian public lighting tools should keep driver load arithmetic distinct from electrical installation work and project documentation.
Examples
| Example | Value | Planning note |
|---|
| Constant voltage | 12 V or 24 V | Common for LED strip load estimates when the strip voltage and total watts are known. |
|---|
| Constant current | mA output | Common in dedicated LED fittings where the driver and LED module are matched. |
|---|
| Dimmable driver | Control method named | The dimming method must be compatible with the control gear and load range. |
