Hello,
I want to control industrial LEDs powered by 24V from an Arduino output. (Here is the diagram of the LEDs)
I thought of putting a booster, but I do not know how it works or if there is a better solution.
Thanks for your help.

I know but I did not choose the correct section, sorry.
OK, first things first.
This is a LED beacon operating on 24 V DC. LEDs are polarity-sensitive, so which connections must be positive and which negative? This one says it will run on AC.
There is no electronic component called a "booster". 
The simple solution would be to use the arduino to drive relays. A quick look on amazon shows that there are opto-isolated relay boards with 24v relays, so the same power source used for the LEDs could be used to power the relay board.
Transistors could be used, but you would need to have more detailed specifications on the LEDs to design it properly.

Thank for your response, attached the led's datasheet.
I want the simplest solution to do that
When I talk about a booster it i like the attachment to go from 5V to 24V.
Thank you for your help.

No, you didn't.
You don''t (except in very strange circumstances) go from 5 to 24 V.
You use a mains power supply to provide 24 V, then you use a switchmode "buck" regulator to drop the 24 V to 5 V for the Arduino.
You may actually find a mains power supply which just provides 24 V and 5 V in the first place.
Ok, thanks for your response.
So, if I understand correctly I have to connect the main power supply delivering 24V to a relay and the relay will be controlled by the arduino to activate or not the arrival of 24V on the circuit.
