Topic: Arduino with Philips LED (Read 3098 times) previous topic - next topic


I am quite new to electronics and recently i've been playing with an Arduino UNO. I am trying to connect a Philips 423244 10-Watt 60-Watt  to the Arduino. Can anyone roughly explain to me what additional equipments do i need and how the block diagram should be? Do i need a LED driver/transistor for the dimming to work?


Do i need a LED driver/transistor for the dimming to work?

You need a matching LED driver with a PWM input.

What's the voltage requirement for that light? Got a spec?

Did you mean "current"?

10 W LED light bulb  reference diagram;-

This is not Philips diagram which I do not know, and it is better not. Philips LED Bulb better use Philips/NXP chipset.


No pwm dim support

Right...it's not a "LED" at all, it's a complete "bulb" with built in current regulator circuit.

PWM isn't going to work (could even damage it).

The only way to dim it with an Arduino would be a digital variac (or a normal light dimmer moved by a servo motor...)

Two types LED bulb;

  • 1. Standard, use diagram I list above which IC is working as 80~230 V AC. The Bulb still has 110/220 V version  since Cx voltage.

  • 2. Dimmable, working fine with variac.
