POLYDOR
Description:
Square recessed lighting fixture with 1 main lightsource (headlight) and an optional backlight. The fixture is available in textured
white or textured black finish. The POLYDOR can be easily installed in various ceiling systems.
Equipped with the PORIFERATM led technology from TAL.
The led module is completely implemented in the center part and the design gap can be illuminated by a backlight.
Thanks to the PORIFERATM technology the POLYDOR combines efficient energy consumption with long lifetime.

Porifera
Porifera is a unique system for cooling powerleds and other electronic components through aluminium foam. The unique
properties of this aluminium foam allow for a much higher cooling performance compared to conventional cooling bodies. LED
light fixtures that make use of Porifera technology have greater efficiency, made possible through the following characteristics :
-
-
Large cooling surface : the foam has an extremely high surface aspect ratio thus creating a large surface within a small
volume. The larger the cooling surface, the more heat can be dissipated.
Low mass per volume : the aluminium foam is very thin which brings the great advantage that the heat is transferred
immediately to the environment (air) and is not first stored in the material itself like in conventional systems. Such
traditional systems have a radiator effect i.e. the material fully heats up and only then interacts with its environment. So
the thicker the material, the slower it cools down. The low mass per volume of Porifera results in a low heat capacity. It
reacts almost instantly to temperature changes which results in very short transient regimes, making it a very
controllable heat exchanger.
Porous : the open cell structure allows for a free flow of air through the mazes of the foam thus securing an optimal heat
exchange with the environment.
Isotropic : the interconnected bubbles form a convoluted path for any gases or liquids flowing through them. Such a
complex path continually brings the gases into contact with the metal walls. This results in outstanding convective heat
transfers. An additional advantage of this isotropic structure is that heat is distributed evenly in a three-dimensional
manner, so the performance is independent of the direction of the convective flow.
Cooling LED fixtures with Porifera is much more efficient than cooling with conventional cooling elements thus providing increased
life span as well as improved efficiency.
An LED’s life span and its efficiency are directly correlated with its junction temperature. This correlation follows an exponential
line i.e. more efficient cooling has an enormous impact on these factors.

Aluminium
Porifera is a passive cooling system that brings all the advantages of an active cooling system without the downsides : greater
efficiency without the need for maintenance and completely noiseless.
Advantages :
-
Longer LED life span
Improved LED efficiency
