Constant Voltage Led Driver Circuit Diagram

The thing is the second module died and i want to replace it with a nodemcu as controller and some dimmable constant current driver as the original one. The voltage drop across an led is approximately constant over a wide range of operating. Normally when you use led display in any circuits often use a resistor for limit led current.

This circuit allows you to use any voltage between 2v and 24v to drive almost any type of led with power consumption up to 5w.

Constant voltage led driver circuit diagram.

I can t go beyond of my budget to buy another power supply driver i already paid a bomb for it. This is a fet constant current drivers circuit for drive led display which can use fet bf256 instead resistor so well. This is a very simple led constant current design using only 2 transistors 2 resistors and an led. 1 fet constant current drivers for led display using bf256.

In the beginning we mentioned using a constant current led driver because these power modules can vary their output voltages to match the series circuit. So theoretically 8 85v is the minimum required input voltage to drive this circuit. Because easy and cheap. In electronics an led circuit or led driver is an electrical circuit used to power a light emitting diode led.

Can i use an constant voltage driver to a parallel led circuit with the resistors connected pls help bcoz i already bought an nes200 36 constant voltage driver and i have an 15nos of 10watts led of 36volts and 300ma. The circuit must provide sufficient current to light the led at the required brightness but must limit the current to prevent damaging the led. The problem is i don t know the total load of the circuit so i drew it nor if i could use a constant voltage driver and mosfets and if i use a dimmable driver what is the correct way.
