Abstract
In this paper the experimental and simulation analysis of a LED weatherproof luminaire is carried out. A CFD model that properly correlates with the real measurements has been created. After this, it is used as a tool to assess different design structures and new thermal solutions, showing that some LED luminaires designs create new thermal problems due to the coupling between the LED's and driver's heat. This problem must be solved or at least decreased in order to obtain higher LED lifetimes and efficiencies. This problem of thermal management is forcing engineers to come up with new solutions for weatherproof luminaires. The use of CFD simulation helps designers to properly understand the thermal behaviour and improve new designs reducing significantly prototyping costs.
