Description
MCPCB-5050CL-20STR: This Aluminium PCB is very flexible. It is designed to take 1 led, with 5.0 × 5.0 mm base, so will suit Cree JR5050, and numerous other 5050* leds with the same base dimensions. The Led voltage will dictate the operation of the chip. This version comes with in series resistor pads so leds can be current limited if to be driven from Constant Voltage Source. Board is usable with the wide range of 5050 led voltages including, 6, 9, 12, 12, 24, 30 and 36Volt
*Please check manufacturers data sheets to ensure compatibility with this PCB foot print
Thermal Path :
Dielectric under the thermal pad of LED
The MCPCB-5050CL-20STR module requires careful attention to mounting and cooling to ensure that the junction temperature of the LED is kept well below the maximum rating as specified in the LED documentation published by Led Manufacturers
For optimal cooling, we recommend that the module be mounted to a suitable heat sink (aluminium Flat plate is perfect but will thickness will depend on the total power used) that is exposed to open air. The module can be mounted to a heat sink in various ways
Before fastening the module to the heat sink, ensure that the two mating surfaces are perfectly flat and clean in order to maximise heat transfer to the the sink.
The bottom of the LED MCPCB is electrically neutral, so it is not necessary to electrically isolate the base from the cooling surface.
Please note the use of Thermal Adhesives makes the PCB unlikely to be removed for servicing. Please consider this if removal of the board is desired as another TIM may be a better choice.
Optics Support:
The board can fit a range of optics from 10mm-30mm arrays, check our Optics category
Optics can be adhered to PCB with adhesives
Assembly Guide for Optics: Ledil have a good generic guide on assembly of Leds/Optics, adhesives etc. Download
Termination:
The ends of the PCB of has Anode and Cathode pads. The PCB can be standalone or wired in groups in Series or parallel.
