Hey Everyone what's up.

This is my DIY Studio Light Project which basically is a do-it-yourself studio light that is made from a custom 3D Printed body and a custom PCB which were both provided by PCBWay.

Question;
Is it better to Buy an expensive Studio Light or Make your own DIY Studio Light with custom 3D Printed parts and PCB?

Well, the goal for making this project was just that, I wanted to make a DIY Studio Light for my current "Maker Setup" as the lighting in my lab bench is not very great.

Project's video-

Commercially available light costs above 50$ (good ones) but why spend money on them when you can make your own Studio Light, Body can be made from a 3D Printer and the circuit can be manufactured by a PCB manufacturer.

But an Important question  "Do these LEDs produce a lot of heat?"

Yes, these LEDs produce a lot of heat so why I'm not using MCPCB (metalcore) instead of FR4 (fiberglass) for making a better-LED PCB that can disperse heat better than FR4 Board.

You see, I have added lots and lots of Via in this PCB, these Via will conduct heat from the top side and transfer that heat to the bottom portion which will result in Heat getting Disperse equally. Then at the backside, there's a 12V Mini DC FAN which cools down the PCB heat.

Apparently, Metal PCBs or MCPCBs are not $$$ wallet-friendly and if I have used a metal PCB in this project, I also have to use another FR4 board for LED Driver IC setup. So I saved a lot by making a single PCB that contains the LEDs and Driver IC setup.

Also, the Body of this light is made from PET-G which is quite a durable plastic so overall, this DIY Studio Light can sustain heat.

So in this post, I'm gonna show you guys the whole building process of this DIY Studio Light, so tight your seat belts and enjoy the ride.

    Basic Structure

    Main Schematic (PDF is attached) is not very complex. The PCB contains two LED Driver IC setups both with their LOAD (LEDs) connected separately.

    Their Input side is connected with each other which is the common Input VCC and GND. we will supply 12V to these two terminals to run this board.

    PCB Designing

    With the Schematic, I prepared the PCB in my CAD software.

    The board outlines were already designed in the Fusion360, I used its measurements as a reference to make the PCB.

    I placed LEDs at the center of the board and maintained an equal distance between them, to keep things symmetrically accurate.

    Also, I've placed lots of Vias in this PCB. Vias cover almost 70% of this PCB and they are here for Conducting heat as well as connecting one side with another side of the board.

    Anyways, after finishing the PCB, I exported its Gerber data and send it to PCBWay for samples.
