Many tier A LED brands like Cree, Citizen and Tridonic have recently boosted their offerings in COB LED packages with new models performing lumen outputs from 10,000 all the way up to 20,000 lumen. As ECO partner of most A LED brands MechaTronix took up the glove to develop a range of high power passive LED coolers.

Five months ago MechaTronix announced their first off-the-shelf high bay LED cooler for designs up to 10,000 lumen with the ModuLED Mega LED heat sink design. Now a second platform of standard LED coolers launches for high bay and industrial LED designs up to 15,000 lumen.

The ModuLED Giga is a passive high bay LED cooler in a diameter of 152mm and height 150mm with an optimal thermal performance of 0.46°C/W. In this compact dimensions 100W of dissipated power, equivalent to 150W electrical power, would lead to a temperature rise of 40°C over the ambient temperature.

The modular design of the ModuLED Giga allows direct mounting of a wide variety of LED modules direct on the LED cooler, without the need of extra drilling and tapping. Most suitable LED engines for high bay designs over 10,000 lumen like the Cree CXA3070 or CXA3590, Citizen Citiled CLU56 third generation, Edison Edipower III HM high power or Tridonic Talexx Stark FLE can be fixed immediately to the ModuLED Giga. Besides modularity on use of LED modules, also on driver and optics flexibility the ModuLED Giga is one-of-a-kind. Creating a flush-look with using the Mean Well HBG-160 high bay led driver on the top, or adding an external driver box for your other driver of choice, it is all standard foreseen.

Optics wise MechaTronix has developed standard optic adaptors which allow immediate implementation of a variety of lenses and reflectors. On the same optic adaptor a wide score of lenses as well as reflectors in aluminium and polycarbonate can be mounted. Design wise MechaTronix has follow here the most common industrial standards one available optics for high bays.

Since thermal validation in this extreme high power range is primordial, MechaTronix performs extended lab tests with combination of each high power COB package in combination with the LED cooler and publishes these results per brand in a thermal compatibility matrix. Small variations like size of the board, pressure of the fixation from the board to the LED cooler, internal junction to case thermal resistance and the use of perfect thermal interface material have such a big thermal impact in this extreme power designs, that MechaTronix advices to ask for consultancy in case of new designs.
