With the current lumen boost of many tier 1 LED manufacturers, the demand raised exponentially for ultra-low profile LED coolers for use in height restricted down light applications Although the increase in
lumen per watt and internal efficacy of recent led COB modules has made the use of passive LED cooling much more likely, most standard LED coolers in the market aimed for classic designs where the cooling surface was created by a smaller diameter with a bigger height MechaTronix now launches the ModuLED Mega 13420
With a diameter of 134mm and a height as low as 20mm, this LED cooler performs a thermal resistance of 1.32°C/W or the equivalent of 5.000 lumen The challenge in this ultra-low LED cooling profiles comes from the spreading of the heat source to the rest of the design Creating enough basic cooling surface in a wide diameter low profile LED cooler is not that hard But the LED COB areas have been shrinked over 40% in the last two years to obtain an easier light image control with secondary optics Also the power density on that area has significantly increased from 25 watts in a 28x28 package to recently 50 watts and more With this major change in light engine approach, the spreading resistance of a low-profile LED cooler becomes the focus point to guarantee the life span of the lighting design
We're really sorry...
...we don't currently have that one in stock
Please add your email and we'll notify you when it's back
