Upgrading my LED ceiling light
After two years in operation, the LED current source in my LED ceiling light caused some problems. The LEDs connected to this current source were flickering. So I had to take everything apart, to substitute the defect current source. I also upgraded the numbers of LEDs. 12 white 3W LEDs were already installed, I added 3 white 10W LEDs (Bridgelux ES Array). They have been kindly provided by Farnell.com.

I also used new current sources from Mean Well – MW LPC-35-700. Rated current: 700mA, DC voltage range 9 ~ 48V.

Altogether there are 15 LEDs with a total power of 66W installed in this lamp – shinging so bright to turn the night into day around my PC desk.
Nice build. I’ll probably adapt something similar pointing towards the ceiling for indirect lighting…
