This information is for engineering discussion purposes and is not necessary for typical users interested in regular use of led strips.
Led strip light driver circuit diagram.
Now you ve got a fully digital controlled high power led light.
The basic principle behind the 230v led driver circuit is transformer less power supply.
12 volt led light strips.
Wiring leds in parallel.
A lot of people are now using constant voltage drivers and wiring up their cobs in parallel since the drivers are usually cheaper and people are more comfortable working with low voltages like 36v as opposed to high voltage series circuits that can be 200v.
Led driver circuits utilize such capacitors which have been a major contributor to premature failures of led lights such as discussed in this article.
The main component is the x rated ac capacitor which can reduce the supply current to a suitable amount.
These capacitors are connected line to line and are designed for high voltage ac circuits.
It is very dangerous to use 230v ac supply on breadboard.

Parallel wiring is most often used when working with constant voltage drivers.
Other popular ones you will see are using the ws2801 driver and strips using ws2812 rgb leds which have the drivers build right in the led package.

Wiring a white led strip or any other strip of single colour leds couldn t be easier simply connect your 240v mains supply ve and ve cables to the input terminals of your led transformer and connect your led strip s starter lead ve and ve again to the transformer s output terminals.
In this circuit we will drive an led directly from 230v ac mains supply.
If your micro controller is 3 3v or less.
Shown here is a strip using the lpd8806 driver.

230v led driver circuit principle.
The micro controller s output pins are only rated for 5 5v usually that s why the zener diode is important.
Adding to all of this circuit complexity and problems are rfi emissions which is a cause of electrical interference in radio devices.
These are also called individually addressable or just addressable.
