Cooling system and LED-based luminaire comprising same

摘要

A cooling system (1) of a luminaire (2) based on light-emitting diodes is proposed, wherein said luminaire comprises a completely closed luminaire construction (3) having a flameproof housing (4). A heat sink (5) as part of the cooling system (1) is arranged in the housing. The cooling system (1) furthermore comprises an electrically operated air circulation means (6). Such a cooling system makes it possible to compensate for the reduction of a luminous flux with minimal additional costs or minimal additional weight or a minimal additional size of the luminaire, wherein the LED lumina can simultaneously be used in hazardous areas in a wide temperature range.
