Explosion-proof LED module

摘要

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. As a result, an explosion-proof LED module can be provided whereby the manufacture of said explosion-proof LED module is relatively simple and possible in an economic manner in a short time from prefabricated parts. At the same time, the explosion-proof module is furthermore characterized in that sufficient cooling corresponding to the ignition protection type “intrinsic safety” and an embedding of the component according to ignition protection type “encapsulation” are given.

主权项

1. An explosion-proof LED module, comprising:
at least one light-emitting diode (LED); a heat sink connected to the at least one LED; and an LED cover that covers the at least one LED at least in an emission direction, wherein the LED cover extends into an insertion recess of the heat sink and is surrounded in the insertion recess by a casting compound resulting in sealing of the at least one LED relative to an outer and possibly explosive atmosphere, wherein the LED cover has a circumferential edge, particularly around an entire circumference, that sticks up in a direction of the insertion recess of the heat sink and wherein the LED cover has a number of insertion elements that stick out from the circumferential edge, wherein the heat sink has an inlay recess running at least in a longitudinal direction of the heat sink, and wherein an LED board is laid onto a cooling surface in the inlay recess, the explosion-proof LED module to replace a tube-shaped fluorescent lamp.
