1. A light fixture comprising a light source, a driver module and a sensor module, the driver module comprising:
a driver arranged for powering the light source,
a driver module enclosure, at least partially encapsulating the driver, having at least one ingress protecting surface area and arranged for providing ingress protection for at least the driver,
a power input terminal, electrically coupled to the driver, arranged for receiving an input power from the light fixture, a power output terminal, electrically coupled to the driver, arranged for providing a first output power to the light source through conductive power transfer,
a wireless power transmitter circuit arranged for wirelessly transferring a second output power through a part of the ingress protecting surface area to the sensor module, thereby providing operating power to the sensor module;
an intra-module communications circuit, arranged for wirelessly transmitting data between the driver and the sensor module;
a communications module, the communications module including,
a module-to-device communications circuit, arranged for communicating with a device external to the light fixture,
a communications module enclosure, at least partially encapsulating the module-to-device communications circuit, having at least one ingress protecting surface area and arranged for providing ingress protection for at least the module-to-device communications circuit,
a wireless power receiver circuit, electrically coupled to the module-to-device communications circuit, arranged for wirelessly receiving power from the driver module; and
a first communications module intra module communications circuit, arranged for wirelessly transmitting data between the communications module and the driver module;
a communications module wireless power transmitter circuit arranged for wirelessly transmitting an output power through the surface area of the communications module enclosure to a sensor module; and
a second communications module intramodule communications circuit, arranged for transmitting data between the module-to-device communications circuit and the sensor module.
