MADE BY NETHERLANDS

Modest and honest human design resulting from co-innovation and the cohesion of public space. This is the Dutch essence of Lowlander. Very much in keeping with the origin of ancestral light bodies, the cylindrical geometry creates a light atmosphere characterized by precision and optical control.

Technical keys

Compact heat dissipation system

The Lowlander heat dissipation system is made of a single, compact piece of EN AC-44100 cast aluminium. Continuous thermal dissipation between the PCB and the exterior improves the conductivity of the lamp. The perimeter arrangement of high power lower LEDs and the central position of the upper beaconing LEDs enables the integration of both systems into a single optical group, separating the opposing heat flows. The complete elimination of air gaps between the PCB and the dissipation body enhances thermal contact between both elements. To achieve this, the body is initially machined and straightened, for a flat, rough surface. A thermal graphite pad of graphite completes the union.

TECHNOLOGY TO PREVENT EXTERNAL DIRT ACCUMULATION

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 Celtika luminaire heat sink with a completely uniform and curved upper surface, thus preventing dirt accumulation, and the ensuing obstruction and inefficiency of the thermal dissipation system. Finally, baffles located on the lower front and rear surface of the optical area prevent dirty liquid flowing from the upper area of the body to the lenses, thereby preserving optical system efficiency (lm/W).

INNOVATION IN THE OPTICAL SYSTEM ENHANCES FINAL PRODUCT PERFORMANCE

he redefined composition of the optical system delivers a 55% reduction in reflection levels, a significant drop when compared with market standards that apply a secondary lens scheme and a tempered glass cover. HTS technology enables optical performance levels similar to those obtained with a direct lens system, increasing the overall efficacy of the luminaire (lm/W) by 8%.
