LED Driver

An LED driver supplies the required output form for compatible LED loads.

An LED driver is control gear for LED loads. Driver type, voltage or current rating, dimming method and load range must match the luminaire system.

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.
