Technical keys
THERMAL MANAGEMENT SYSTEM
The LAFS® (Lateral Air Flow System) side cooling system generates an internal convection process to reduce the temperature of thermal critical areas, where the luminaire body comes into direct contact with the PCB. Finally, the use of a graphite thermal pad in the area between the PCB and dissipation body contributes to thermal contact optimization between both elements, eliminating air gaps and improving the dissipation process in the early stages.
HEAT DISSIPATION SYSTEM
The dissipation system of the Urko floodlight is integrated by 4 equal pieces with modular design and assembled in a solid and permanent way forming a rigid set of injected aluminum EN-AC-44100 (L-2520). This dissipative assembly also constitutes the body and shape of the luminaire itself, so that the dissipative mass is very high. This, together with the hollow grid design, makes the Urko a product with very high dissipation and cooling capacity.
This design allows the implementation of a continuous thermal architecture between the PCB and the luminaire volume. The 90° perimeter arrangement of the high power LEDs allows a more homogeneous distribution over 360° so that when used as a floodlight it has a wide range of possibilities.
The complete elimination of air gaps between the PCB and the heatsink body favors thermal contact between the two elements. To achieve this, the heatsink body is initially machined and ground, thus ensuring an optimum level of flatness and surface roughness. Subsequently, the aforementioned graphite thermal pad is incorporated into the meeting area to achieve an intimate bonding level.

TECHNOLOGY TO PREVENT EXTERNAL DIRT ACCUMULATION
As in indoor use the dirt accumulation is limited (mainly dust), this feature is optional. According to the US Energy Agency, relief on the upper surface of the fixture severely hinders the dissipation process that takes place by convection, becoming a critical element for performance and life.
To overcome this challenge and to enhance the natural self-cleaning process, SETGA has equipped the Urko projector with completely uniform surfaced special pieces, installed over the dissipating fins, thus preventing dirt accumulation, and the ensuing obstruction and inefficiency of the thermal dissipation system. Those pieces cover above the fins and allow the natural flow of dissipated heat by the fins through both open sides. Customer can choose to add the cover pieces to keep it clean or to leave the dissipation fins wide open to the air.
