Cree Luxeon LED bulb repair
How to fix MR16 type 12V LED bulb by Avi
Don’t trash it, don’t make the situation worst. You can contribute to keep our planet cleaner.
You can repair it and I’ll show you how.
These kind of bulbs uses few Cree led components and in most cases one of the leds fails which causes the bulb to stop emitting light or emit a very dimmed light. Replacing the faulty led will usually solve the issue and allow further use of the bulb.
This page will show how I replaced a fault internal led and fixed the bulb.
DISCLAIMER – Important!
- Phillips head screwdriver
- Solder iron and soldering accessories
- Working Cree / Luxeon led (this could be taken from another fault bulb)
- Thermal grease / heatsink compound
Pay attention to wire colors and position on the PCB. You don’t want to blow this part.
Leds driver PCB (small one) can now be removed which will release the leds PCB.
Note that in some models the rear part of the leds PCB is made of metal to allow proper cooling.
This part is attached to the metal housing with a thermal grease. If this is the case, clean the grease to allow easy handling. You’ll need to apply new grease when assembling.
Desolder the fault led and solder a good one keeping the same polarity.
Do not forget to add thermal grease to the rear of the PCB, these leds are sensitive to heat.
Pay attention to the closing force of screws. Don’t use excessive force !
Have fun and enjoy your lighting, Avi
