Hello, I am a recent graduate and I recently joined a company that makes street lighting lamps. All good and beautiful until I was told that I had to look for a driver for LEDs that would convert a direct current of 12 to 24 volts into a direct current of 36 volts. The main question is what device do I need to control the power? For example, the LEDs would draw 36 volts, how I can change the output current so that they can adjust the power they consume, for example 50w or 30w. The power supply would be made by two 12v batteries connected in series, which output 4 amps at 24v. Any links would be helpful, thanks!
I would look for something (the key words: boost or step up, current source, Led driver) like DC-DC 8.5-48V To 10-50V 10A 250W Continuous Adjustable High Power Boost Power Module Constant Voltage Constant Current Non-Isolation Step Up Board

Firstly, terminology: Current is measure in Amps, not Volts and we use caps because those units are named after people - Ampere and Voltaire. Also W for Watts. Pardon my pedantry ...
Secondly, search the internet for a "DC to DC converter". Try to find one with a smooth output - cheap converters can have a chopped output waveform which is not really "DC".
There's some converters here:

Good luck ...
