Upgrading my LED ceiling light 1


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.
