Heat dissipation
Most people see led profiles as pieces of aluminium, whose only purpose is to show a led strip in a more or less fancy manner. The truth is,
esthetic is one of the purposes of the led profile, but the concept of led profile itself goes way beyond that!
Led strips with lighting performances of 100, 140 and even 180 lumen per watt have increasingly gained popularity on the market. Since the heat
levels generated by these led strips are very high, the lifetime of the led will shorten, unless we use a better heat dissipation system.
By correctly designing a led profile, we can enhance its heat dissipation ratings up to 30% more when compared to a non-optimised profile, which
has the same aluminium content.
Optimum ventilation through thermal conduction (therefore implying the highest values of absorption of the heat generated by the led) will be
achieved with the led profile by settling a balance between the amount of aluminium covered by the profile and the geometry of its design. On
the matter of design, protruding surfaces and channel-shaped areas are elements of utmost importance in order to avoid resistance against the
distribution of thermal energy.
When our led profiles are being designed, these and other issues such as, for instance, accuracy of the finishes are taken into account (an
anodising process will always provide higher levels of stable heat dissipation to the profiles when compared to a lacquering process). By doing
so, we manage to achieve functional profiles, which are also competitive in terms of pricing.
Table of contents covering the heat dissipation ratings for our most popular profiles:
All measurements have been registered under 25˚C temperature and once the working
temperature has become stable (after 45 minutes).
The indicated values have been obtained by combining a led profile with the ecoled
item Zafiro, the latter having as values of power and stabilization temperature 14.4W/m
and 38˚C respectively.
*With special mention to the Detroit profile, whose values have been obtained by
combining it with the ecoled item Cíes, the latter having 49˚C as stabilization temperature
and a PCB thickness of 5mm.
