Hi all!

I am opening this thread to announce my latest and patent pending development that is a LED diffused ring light illuminator.
Problems with the LED ring lights and critics about their glare, distracting hotspots and streaks of light have been discussed in older threads of this forum. At the time of reading those posts I thought in some solutions but had not the opportunity to make my move until the past year.

All the effort was aimed to combat those pinpoints of LED light that can be painfully bright and annoying, specially when you are engraving on shiny surfaces or setting diamonds because they cause too much sparkle on gemstones.

Along the past months I developed six versions of the ring light illuminator (with some sub-versions too!) and built the first one and the last one. The first one was nice but very expensive to produce. From that point I kept iterating until I found a design with the same optical performance but with less parts and easier to build.
Finally I made the 7th version, the last and production one, which is entirely CNC mechanized in 6082 aluminium alloy anodized in black.

28 medium power SMD LEDs are mounted on a gold plated aluminium circuit board. I designed the LLE (LED Light Engine) in a way that the LEDs are working in a medium-high range of their power but without pushing them to their limits. This should assure that the LEDs will last thousands of hours. The LEDs I have chosen comply with the LM-80 standards so the lifetime expectancy should be more than 60,000 hours but the more important data is that they will still have a lumen maintenance of 96.2% after 10,000 hours of continued use.

Special care was taken in every detail of this state-of-the-art ring light, even in the time invested looking for a good and very flat actuator capable of withstand the pass of the time and a heavy use. This switch is rated to 1 million actuations, way far of some crap you can find over there.

All in all, the DLI-W01 ring light will give you a soft an evenly distributed dimmable light, with a CRI (color rendering index) of 80 or better and 6500º K of color temperature (Daylight), with enough power to work at about eight inches in the case of 0.4x Barlow lens users, for a long time, without maintenance and consuming only 12W.

Dimensions.
Ring Light: 60mm ID. 120mm OD.
Power unit: Aprox. 170 x 80 x 30 mm.
Linking cable: 750 mm.

I made just a few units to test how much interest would be in this product so please, let me know here or by a PM if some of you would like to buy one. Price and shipping information will be provided privately to comply with the forum rules.

Cheers! :)

texascowboy, the internal diameter of the ring light is 60 mm so it can be attached to any microscope that has a objective diameter of 60 mm or less. Unfortunately I do not know the diameter of all microscopes objectives but I know that it will work on Nikon SMZ, Leica A60 and Seizz Stemi 2000. It is necessary an adapter to be attached to a B&L StereoZoom 4.

Looks like you have a nice product there.
The glass on my Leica mz6 is 50 mm so I assome it would slip around.
My AO is smaller I'm sure.
I think you've made it a good size for versatility.

Thank you Chujibear.
The ring light has three screws to center it at the time of attaching the unit to the microscope objective so no chance of slipping around at all.
60 mm of internal diameter seems to be a standard for most ring lights illuminators. The adjusting screws can take an objective of 30 mm or even less.

I am interested also. I have a Leica A60 and Leica S6E. Will it fit both? I live in Australia, hope that is not a problem. Thank you.

The voltage here is 240 volts, i also hope this helps.
Sorry just noticed in a picture it states it is multi voltage. I am viewing this on a small tablet.

This week started well with that I get home a new workbench made by MPF in Italy
And today I got magically good ring light from Artesa Spain
I have thought that the Leica lighting with diffusor has been good.
but this is almost ridiculously good.

You are welcome Joacim and many thanks to you for your confidence. Much appreciated!
Your new bench and setup look great. I am really glad that my ring light fulfilled your expectations. Enjoy it!
