I bought a IKEA Jonisk lamp to have in my living room, but when i powered the lamp up with a 60W bulb it become hot as ****. I started to figure out how to convert it to a LED-lamp instead.
I found a company that sells high powered LED modules (www.leds.de
). I ordered 3 SEOUL P5 RGB LED that already was mounted on a PCB. For controlling the LEDs I choose a PIC16F628A and 3 TLE4242G constant current sources. After that I found a remote controlling kit laying around in a box, so I added it to the project. By controlling the current sources with a uP and PWM, I now can blend the lamp to almost any color I want. And it use much less power now and generates almost no heat.
This project was not supposed to be on Instructables.com from the beginning so there is a lack of photos in the instructable.
