Custom Diffuser for LED lighting.

So after watching:

Where BRS investigates the Philips Coral Care LED light.

They came across with a significant breakthrough with how Philips implemented a diffuser for the LED's to blend the LED's together.

Basically they put a frosted glass plate on the bottom to diffuse the LED's and blend them for almost perfect uniformity. Something no other manufacturer has done.
They came away from the test pretty blown away by this, and said they're positive other manufacturers in the future are going to copy it.

I'm thinking of attempting something on my new 420 gallon build with the G4 Pro's I'll be using.

Basically have a piece of tempered starphire glass frosted and acting as a diffuser for these lights.

Make a mounting bracket which will have the G4's standing off of the glass on architectural standoffs, and then that pane of tempered glass would would be suspended at whatever height I choose.

I own a signshop and have various frostings including colored frostings available to try, including some with different opacity's.

I would be able to make it look pretty gorgeous.

Of course the lighting itself would have safety hookups incase the glass broke, however I would make sure the pane was a sufficient thickness. Plus we hold so much water on a glass pane, I'm not really concerned about the weight of some lights.

3 Radion G4 Pro's diffused to provide better uniformity.

The only issue I forsee is the Philips uses a substantial array of LED's in a large area, whereas the Radions or others use pucks. This could be fixed by simply raising the Radions higher up from the glass.

What are you thoughts, suggestions.

Thanks.
 
Try it and if you can make it work well, you have a new income stream around here :)

The only issue I see is that the other LEDs, like Radions, that weren't designed with a diffuser in mind have the LEDs pretty close together. The CoralCare has the LEDs spaced out pretty nicely to create a big blanket of light after the diffuser.
 
There is geometry to consider..

White Diffusers for heavy to medium diffusion of the beam.
Tough Spun Diffusers for light diffusion that also adds a subtle texture to the beam.
Tough Silk Diffusers that offers heavy to medium diffusion and directionality control of the beam.

Each type offers some differences.. between diffusion and linear transmission..

Point is diffusion needs to be measured as to how much light is also lost over the target area..

I have the ability to obtain tons of different frostings and types with varying opacity's & colors as well as printing them. Maybe make the glass so you can slide in different films for diffusion to figure out which is the best without having to apply it.
 
Diffusers over light sources... Now why didn't someone think of that.. Oh wait.. Nothing new.. :)
I used the same concept on the first DIY LED light I did over 10 years ago.. Worked pretty well..

Not sure how this sarcasm benefits anything. I never suggested I was doing something that's never been done. Diffusers existed before we were both born.

Please share your findings and what you discovered.

An actual contribution would be great.
