How to maximize system lifetime?
Ensure good thermal contact between module, driver and the coldest part of
the luminaire
Place module(s) and driver at a distance from each other to obtain a more
homogeneous temperature distribution in the luminaire
It is recommended that the modules are mounted on an aluminum housing that is
at least 3 mm thick; thinner housings will limit the heat flow through the housing,
while thicker housings will improve the heat flow through the luminaire, resulting
in a lower Tcase of the module
Important points for luminaire design
When multiple modules are used, it is recommended they are spread out in the
luminaire, in order to distribute the thermal load
Reflectors should be used in the design of optics
In order to accommodate every application, Fortimo LED High Brightness
Modules can be dimmed or used in pairs to optimize the lumen package
Simplify the heat path from modules to ambient air. Limit the number of thermal
interfaces in the primary heat path towards the ambient air
If thermal interfaces are inevitable, use thermal interface materials (TIM) to
ensure proper thermal contact, i.e. between module and luminaire housing
Ensure proper heat dissipation by using highly conductive materials and/
or materials of sufficient thickness to maximize effective use of the available
cooling surface
Use anodized, painted surfaces rather than blank surfaces in order to increase
the transfer of heat via thermal radiation
