Modules for providing intrinsically safe electrical output power and explosion-proof luminaires

摘要

The present invention relates to an explosion-proof luminaire (22) or a module (10) for an explosion-proof electrical device. The module 10 is designed to convert each non-intrinsic safe input power on the input 11 to an intrinsic safe output power on each of the plurality of outlets 17. [ A corresponding electrical load, for example the light emitting diode arrangement of the at least one light emitting diode 21, can be connected or connected to each outlet 17. The outlet 17 may be connected in parallel or in series between the first inlet connection 12 and the second inlet connection 13 of the inlet 11. At least one current monitoring device 27 monitors the output current IA. At least one voltage monitoring device 27 monitors the outlet voltage UA. As soon as the outlet voltage UA exceeds the voltage limit and / or the outlet current IA exceeds the current limit, the safety switch 16 is switched to the disconnected state by the control circuit 28.
