Teardown of a ikea trådfri bulb (LED1623G12)

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...

Teardown of GU10

Teardown of the GU10. This lamp is good for two reason, price(around 7€) and no potting compound. The plastic lens is just to pop out from the case. Two hooks holding it place. No potting inside. To remove the Led board two tabs must be desoldered. Ikea have also added a strip of copper, probably to solve some EMC problem. Also it easier to pop out the pcb with a machine vice and press on sides.
