DIY IKEA Tradfri lamp
I have been diy'ing for a long time, but sharing hasn't been my top priority.
Nevertheless, with the pressure suffered from my coworkers, I decide to bring it online.
On my first post I will try disassemble a IKEA Tradfri bulb, reusing zigbee board to power a LED strip
Starting with a IKEA Led bulb and a led strip
At this point I have connected the bulk to the mains power and I got disappointed, no power on secondary.
In conclusion
Bulb disassembly was a pain and the result was far from expected, as, after I tear it apart, very low voltage was being given from secondary, 0.5V, too low to power led amplifier.
Perhaps I have made some short while separating it from rubber insulation, perhaps it was just my somehow short knowledge on electronics. As far as my feelings concern it is just a blown fuse.
Never mind, I will be back to her soon.

On first approach I have cut the bulb where both plastics join, this way I'm trying to avoid cutting led board
Job done, lets remove leds board.
Bad luck, It is quite different from pictures I've seen on the web, the core is isolated with a aluminium metal case, believe it is part of heat sink.
I have decided to cut it a little below. but the metal case is all around. I had a really bad time breaking it apart.
Finally I'm in, and with it I get more bad news, there is some kind of rubber past all around, good news for IKEA, it looks they did a excellent job insulating electronics
Finally...

Dumb question, but did you check the dim level or if it was off maybe?
ReplyDeleteI had the same idea with the strips. I will get it an give you some feedback if it works.

Yes, I did, the secondary (12 V) circuit is dead, zigbee chip still responds ok, my next idea is to use chip only and build a pwm circuit to power the led strip, the main problem might be with overall power, since I have 12 meters is 10W strip. Probably I will end with tree segments with led amplifiers in between.
