LIGHTING ASSEMBLY WITH AIR COOLING

摘要

A lighting device (2) generating excess heat has a cooling area cooled by a fluid flow generated by a fan device (10). A fan motor (6) driving the fan device has an electromagnetic motor circuit. Part of the electromagnetic motor circuit forms part of an electromagnetic generator circuit. The electromagnetic generator circuit supplies the lighting device. The combination of the electromagnetic motor and generator circuits provides a compact and low-cost construction which can be connected to a mains voltage without electric conversion. The lighting device may be an LED device.
