Abstract
There is provided a lighting device 100 comprising a light source, a driver arranged for powering the light source, which is separated in space from the light source. The lighting device has two separate heat sinks, a light source heat sink 112 to which the light source is thermally coupled, and a driver heat sink 115 to which the driver is thermally coupled. The light source heat sink and the driver heat sink are separated by an air gap 114 to provide thermal decoupling of the light source heat sink and the driver heat sink.
