How to Make a 50W LED portable 12v DC

How to Make a 50W LED portable 12v DC

In this tutorial for making a 50w LED movable and work only with 12v DC We need

1- 50w LED (Floodlight)

2- 12V battery

3- fan for cooling down LED (this is CPU fan)

4- 12v to 30v Dc to Dc converter 

Also you can see this link to learn how to draw dc to dc converter circuit  (Dc to Dc converter ) 

And this video help you to complete your project 

And this is some photo of the project 

How to make Dc to Dc converter

How to make Dc to Dc converter

Some timeyou have 12v battery and you make a project it need more than 12V so you can convert 12v to any voltage you need
For this circuit you need
1- Transformer

2- Two Power MOSFET

3- Pwm controller  (TL494)

4- some resistors and capacitors 

This is a Dc to Dc converter circuit

You can see this video it help your circuit step by step
