Philips Lumileds signs up with MechaTronix for partner LED coolers

With the launch of the newest generation Philips Lumileds Luxeon Chip-On-Board (COB) LED modules there was an immediate need for a wide range of standard LED coolers
In the cooperation with MechaTronix Philips Lumileds found a practical and easy way to launch a wide range of standard LED coolers fitting mechanically with the various dimensions of the Luxeon COBs and matching the cooling capacities needed for the whole series
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
