Hi there. I have a LED strip that comes with a rectifier. So it changes the 220VAC to 220 VCC. LED strip works in 220VCC.
I need to find a dimmer that works for this kind of LED strip and is Home Assistant compatible (and works unde WiFi/BT/Thread). Any ideas?
Thank you very much.
Things don’t match here. 220VAC rectified doesn’t make 220VDC.
It’s better that you post more details about your device/circuit.
Hi. It comes with a rectifier that converts from 220 VAC to 220 VDC. I tested with a multimeter and seller told me the same.
Then it has some voltage regulation circuit, not than just rectifier. 220VAC rectified gives >300VDC.
But the point is same, you should provide more info to get reliable answers.
Hello Juanpermon,
Well I can tell you one thing for sure, the LED’s don’t run at 220 volts. That is fed thru circuitry that brings the voltage down to less than 5 volts on each of the LED’s. The only kind of ‘dimmer’ you use there should be specialized and built for the circuit involved.
What ever you are thinking about doing, don’t do it…
Yeah, I know, 220VDC is a very dangerous situation. LEDS run on this voltage for sure, I tested it.
The only plausible solution I can’t think of is buying their official dimmer remote control and control it with ESPHome with an IR sensor.
LEDs are current controlled, voltage is not relevant as long as it’s higher than the sum of LED forward voltages in series. High voltage drivers are commonly available, but you need to dig information about the current.
I don’t think I can follow you here…
Simply, LEDs are current controlled, not voltage. You need to find out how many milliamps.
If you are looking for help here, you should post what you have, model, link to the device, photo of the labels etc…
Depending on what kind of light you have and how its fed that is not true.
For example if you have a led strip those tend to be constant voltage fed. 12 or 24V DC most of the times. Single led lights tend to be in mA and are in series and will need a constant current driver.
So its VERY important to know how the light source needs to be fed according to its maker specification. Dont make assumptions with knowing what is EXACLTY there.
The picture you posted is a constant VOLTAGE driver, so you are contradicting yourself right there. Its even says MAX 1,1A so it will vary depending on the load.
As for the OP: Post some specs about the driver and ledstrip. Otherwise this will end in tears.
I didn’t propose that driver, it was just an example of high voltage driver, showing that 220vdc LEDs are not something weird.
Even 12v or 24v strips are current controlled by the strip circuit.
Voltage control of LED is extremely difficult because the range is just some millivolts and temperature dependent.
