Philips Lumileds Signs Partnership with MechaTronix for LED Thermal Management Solutions

Six passive coolers have been launched, ranging from a diameter of 50mm for the Luxeon COB 1203 and 1204, over a diameter 70mm and 99mm for the COB 1204, 1205 and 1208:
With this passive LED cooler range MechaTronix aimed at spot, track and down light designs from 600 lumen all the way up to 4.500 lumen in a small size extrusion profile. The ModuLED Xtra LED coolers are developed in this way that there is an optimal balance between creating cooling surface and leaving enough intermediate space for free air convection.

In this way MechaTronix was able to reach a ModuLED Xtra cooling performance of 1.02°C/W in a package of only 99mm diameter and a height of 80mm, and keeps the Luxeon 1208 COB running at 4.800 lumen at an ambient temperature of 40° Celsius below a case temperature of 80° Celsius.

For those applications running at an extreme high ambient temperature, two active coolers packages where designed:
The IceLED Xtra active LED coolers are developed in a package for indoor low bay use with an extremely low noise factor, this delivering a cooling performance of 0.46°C/W.
This makes them extremely suitable for spot, track and down light designs in office, shop environments and silent rooms where extra noise has to be avoided

All ModuLED and IceLED coolers are foreseen from direct mounting patterns for the various Philips Lumileds Luxeon COB’s, but also offer Zhaga book 3 mounting holes so designers can use COB LED holders if they require solderless mounting of the COB’s on the coolers

MechaTronix performs thermal compatibility tests on all combinations of the Luxeon LED COB’s with the various standard coolers:
A major point of improvement according Koen Vangorp, General Manager of MechaTronix, is the extreme low internal thermal resistance of the Luxeon COB’s. “Philips Lumileds clearly understood the mission of developing high lumen packages in combination with a low thermal resistance. Maybe it is not so obvious to understand what this means because most LED manufacturers offer an external thermal measurement point and all publish similar numbers for these, but the consequences are enormous. With these low thermal resistances from junction to case Philips Lumileds is able to keep their junctions easily 10 to 15 degrees Kelvin lower than most chip-on-board modules on the market. And that immediately affects the life time of the LED dies in a very positive way. Either designers can take advantage of this by using smaller LED coolers, or just use the same LED coolers like they did before but gain on life time.”

All MechaTronix LED coolers are off-the-shelf available through their worldwide distributor and agent network
