A RING LIGHT is a circular photographic electronic light that fits around a camera lens or surround the camera . Unlike spot light sources, a ring light provides even light with fewer shadows as one light source compensates for the other visible in the resulting photographs because the origin of the light is very close and surrounds the optical axis of the lens.Lester A. Dine was the inventor of ring light in 1952 for use in dental photography,but now is commonly used for portraits, macro, and fashion photography.
this is just a prototype which I made & the second version will be developed soon.
Step 1: Parts Needed
You will need below parts
20x 5 Watt SMT leds
1x Voltage step down Buck converter
I used a 3mm thich 8.5 inch aluminium utensil lid
Mains cable wires
20Volts 3Amps Laptop power supply
Step 2: Cut a Circle Inside the Aluminium Lid
I cut a 4 inch diameter circle in aluminium lid on a lathe machine
sanded up the sharp edges with a sand paper to smooth the sharp edges
took the 5 watt smd leds applied thermal grease and placed it in circle.
took a acrylic piece cut a 4 inch diameter circle.
now after this if you want to replicate it the same way then need to use the exact measurement of your lens and then cut a circle inside so that it can fit just above your lens
With my luck I got the acrylic piece exactly fitting on my lens.
Step 4: Solder the Leds
Once the leds are placed you need to solder place it in parallel
Positive & GND IN parallel.
recomend to use thick gauge wire and solder in
Step 5: Circuit Diagram
Please check this circuit Diagram for reference.
Step 6: Adjusting the Power Supply
Connected the leds to variable power supply & multimeter to check the optimum voltage
with powersupply of 20 volts and connecting a buck converter to it it was coming to 11.8volts with 2amps current.
Step 7: Attaching the Ring Light to the Camera
So once its done then need to take few rubberbands and stick it to the acrylic cutout like how i have done
recomend to use a spebb7 or epoxy glue or use hot glue(hotglue not much reliable).
and then connect the power supply.
Step 8: Test Photos
So first thing I did is clicked some macro photos and turned out really good.
Can also be used for vlogging, video making, potrait shots
Step 9: Review & Improvisation
The Rig turned out really nice however there are few things which I noticed which I would like to tell you.
Heating because the aluminum lid was thin so the Picture what you see above is the second version of it in which I used a thicker plate ( Instructables for the ring light ver2.0 will be uploaded really soon).
