Constant current high voltage dimmable led driver



  • Hello everyone,

    I've been playing with MySensors mainly with relays, bounce door sensors and rgb led 12v driver.

    Today I would like to "MySensorize" a dimmable dual channel ceiling light I've just received.

    Here are some pics of these 2.4 Ghz led driver, providing 240mA@130-185V

    The receiver is on the yellow PCB and my goal is to find how to replace this specific part with an arduino.
    I've found it receives 5V DC

    The 2 channels correspond to 1 warm and 1 cold led strips.
    If I can find how to PWM the green board with your help, I will then work on code for piloting it with a dual monostable button (one for on-off-dimming long press and the other for switching between warm/cold/natural)

    The ceiling lights itself is this one

    it has a lot of spare splace so it's easy to include the arduino.

    Hope someone has ideas of how to PWM it.

    Thanks
