Abstract: An explosion-proof LED module has at least one light-emitting diode, a heat sink connected to this and an LED cover that covers the LED at least in the emission direction. The LED cover extends into an insertion recess of the heat sink. In this insertion recess, the LED cover is surrounded by a casting compound resulting in sealing of the LED relative to an outer and possibly explosive atmosphere.
