Abstract

An explosion-proof luminaire comprises a plurality of light-emitting diodes. These are assigned to a ballast for electrical power supply. A contactless power transmission device is formed between at least a group of LEDs and the ballast. This yields an explosion-proof luminaire which is simplified and improved in terms of structure and light output while permitting many possible arrangements of the LEDs in the corresponding luminaire at the same time.
