Teardown of a ikea trådfri bulb (LED1623G12)

Teardown of a Ikea Trådfri bulb.

Steps performed to take out the electronics:
  • To remove the sphere i cut the plastic just where the base starts.
  • Next step is to remove the LED ring on the aluminium PCB, just desolder the two tabs and remove screws.
  • Next step is a little bit harder, here i used a vice and deformed the base to get the "heat spreader" off
  • The E27 cap was removed by cutting the cap and use a plier.
  • The electronics with the potting compound can be removed from base by using a vice again to deform base.
  • Remove the potting compound is relative easy, it have a structure of dried clay and a removable type.
  • Now the PCB is clean  

The lamp seems fine from a electronic and heat perspective.
All electrolytic capacitor is marked 130°C and the casting compound is probably to spread heat to base aluminium case and electronic isolation.
The led ring is two serie connected strips of 9 leds each. The Aluminium PCB also has heating compound between the PCB and the "heat spreader".
The Zigbee module is the same as the remote with 5buttons or the PIR sensor.

  1. The GU10 warm white are cheaper (£7 in the UK) even easier to take apart. You can disassemble them non-destructively with just a couple of small screwdrivers. Not even any potting compound.

    1. I think the GU10 was not available when i performed the teardown.
      But thanks to the tips, the cost is similar in sweden.

    Thank!
