DIY Photography LED Light

Introduction: DIY Photography LED Light

DIY Photography LED Light
Photography is an art that requires patience and dedication to master.People Who are Photography field or just do it as a hobby very well know that Light plays a crucial role in the end result of your photo.
I am not a photographer but I do love making projects. For that, I require a good lighting source so everything looks perfect and real.
So I decided why not build a photography light that could fulfil all my needs.

Step 1: Gather Your Parts

Gather Your Parts
Go ahead and buy out these products:
  • 50W DriverLess LED
  • Aluminium Heatsink
  • M3 nuts and bolts
  • Thermal Compound
  • Spray Paint
  • Wires
All the stuff you can buy from your local hardware store.
But the thing that you may not find is the LED itself. I have included the link. So go and purchase the Item.


Step 2: Working and Choice of LED

Working and Choice of LED
The main aspect is which LED to Buy because there are so many options out there and it may drive you crazy.
So, the point is How to buy this led.
While selecting LED for your lighting needs make sure it follows these parameters.
  • The Power of LED Required
Now, this completely depends on your preference as You may be a 20W ,30W or even a 100W. This all depends on your needs. 
  • The Colour of LED
Next, comes the colour. Now here also you have a lot of options to consider. You can buy a Cool White LED, Warm White LED or you may go crazy and buy an RGB LED. 
  • Power Source
Selecting the right Power source for your LED's is quite Important. Now, this has to be chosen carefully.
You may go for a battery source, AC- DC adapter, or you may also buy an SMPS Power supply. But needless to say that all these Power sources are bulky when it comes to their portability.
As the technology is evolving, Now we have a driverless led that doesn't need any sort of Power regulation or ac - dc conversion. It directly runs from the mains wiring.
Now while buying this LED make sure that the voltage source is compatible with your country's mains voltage.
I have chosen a 220V one as In India We have 220V mains.

Step 3: Preparing the Base

Preparing the Base
Now this build is pretty straight forward and anyone can do it without any problem.
First cut a piece of an aluminium heatsink according to your need.
After Cutting the Aluminium Heatsink to the desired length use bastard File to remove any sharp edges and corners that the piece has.

Step 4: Making Holes and Painting

Making Holes and Painting
Next, use the  LED itself as a template and traced out the holes and outlines on the aluminium heatsink.
After the Holes were marked use a drill machine to make four Holes on the aluminium Heatsink where the LED will fit.
Next, use some transparent adhesive tape to cover the area where the LED will sit. This is important that you do not paint this area as it will reduce the thermal heat dissipating ability of the Heatsink.
Now use  box cutter to cut the excess tape from the template.
Then  sand the surface of the aluminium heatsink so that  it appears uniform.
Next use  black colour spray paint and gave it two coats of it and let it dry for 30mins.
After drying it overnight, examine the piece for any mistakes that you have made.

Step 5: Fixing the LED and First Test Run

Fixing the LED and First Test Run
Now use Thermal compound and applied it to the place where led will fit.
Apply a generous amount of it as it will help transfer the heat better and your LED will run Cooler and safer
Now use 4 M3 hex nut and bolt and fix the LED onto the aluminium piece
Make sure You Secure it very tight so that it makes a good contact with the aluminium piece.
Now solder The Live and Neutral wires to the Pads marked With L and N on the LED.
TIP: - Use a good Thermal Capacity Soldering Iron as the aluminium substrate on the LED will absorb heat a lot and you may find that you have a cold solder joint.
After This, connect the LED to the mains supply and turned on the switch.

Step 6: FINISH

In the end, fix the whole assembly on the place of your choice.
 It can run for  maximum from 5 to 10mins. During this time the Aluminium Heatsink gets quite warm. If you want it to run for a longer time than you can attach a fan and a bigger heatsink to it.
