Finally finished my homemade multi-radiance LED therapy device.
10 660nm Red LEDs
10 880 Infrared LEDs
Pulsing at 50hz

Can be worn on the knee, ankle, wrist and elbow to help reduce inflammation by increasing microcirculation to ligaments and tendons to aid in healing.

re: Finally finished my homemade multi-radiance LED therapy device.
What's the theory behind this?

Reduce inflammation by improving microcirculation to the ligaments and tendons.

My wife’s vet clinic has them for pets and the same company sells them for human usage but the specs are identical. They bought one big device for the clinic and 3 travel versions they could rent out to clients.

One client had it rented for a month and bought it outright because it helped their pets tremendously with joint pain/arthritis. Pets don’t know WTF is going on so there is no placebo effect.

The one they sell to us cost $2500. I built it at a cost less than $20.

Here is a link discussing the benefits of LED therapy from one that manufactures them.

Joovv

If anyone wants the plans, I can sketch it out at send a pic of it. I used an LM555 chip and RC circuit for the 50hz pulse.

50 HZ LED device
LM555 Chip
R1 at 220 ohm
R2 at 200 ohm
C1 at 47 uF
C2 at 10 uF
660 nm Red LEDs
880 nm IR LEDs
9V battery (I'm upgrading it to a plug-in 9VDC source in the next week or so)

For a 250 HZ device, you need R1 at 36 ohm, R2 at 43 ohm. Everything else remains the same.

I built one with 10 660 nm & 10 880 nm, but you can adjust this per your design. I created a 4x5 design with the LEDs in a symmetrical pattern.

Also, since I wanted it flexible and needed to be insulated, my base is a mountain bike tire split and cut as needed.

You can also do this in an arduino chip without using the RC design.

re: Finally finished my homemade multi-radiance LED therapy device.
I upgraded to an AC/DC adapter and pumped too much current through it and it fried the LEDs after a few minutes.

It was starting to burn.

Rebuilt the LED assembly quickly.

Pencil sketch.

Shows a 555 chip, where to land everything on the 1-8 pins and all components.

LED bank can vary. I have mine as 4x5. And I don’t have a switch, I have a quick male/female disconnect.

One less thing to solder.

I'm ordering at 9V 500mA AC/DC adapter. I think that's low enough so that it won't fry the components.

re: Finally finished my homemade multi-radiance LED therapy device.
I did the math on parts to build one, and it came out to just under $11.00.

I did buy enough to make several more. I'm building two more over the weekend.

re: Finally finished my homemade multi-radiance LED therapy device.
The 9V 500mA AC/DC adapter appears to be working well.

It isn't burning my skin and isn't frying the LEDs.

So if you guys design it with a 9V AC/DC adapter with a max output of 500 mA, it'll replace burning through 9V batteries.

re: Finally finished my homemade multi-radiance LED therapy device.
Day 5 Update

I've used it 2-3x per day around 10 min per session after I finished it on Sunday. I managed to get through a long snatch workout a few days ago without my knee bothering me at all, and, previously, high impact movements like C&Js and Snatches would irritate it during the workout.

Sure, it could be placebo affect, but the irritating pain that has been bothering me for a couple of years is down considerably even with me continuing daily workouts.

The upgrade to an AC/DC adapter will guarantee constant output compared to using a 9V battery which will start to fade when the battery loses power.

If this continues, and the pain goes away completely over the next few months, I'll try to get a follow-up MRI to the one I had 16 months ago to see if the low grade tendonosis is still present.

Not to be mean here, but a heating pad does the same thing...

re: Finally finished my homemade multi-radiance LED therapy device.
The LED therapy is different: It’s a cold activation that penetrates deeper vs topical heat (from a pad).

quote:

Infrared LED pain relievers, in the form of cushions, pads or mattresses, can be more effective than the use of traditional heating pads. Originally developed by NASA, the FDA-approved light therapy is used for temporary relief of aching joints and muscle pains, increased blood circulation and relaxed muscles. Since traditional heating pads are non-infrared, they are usually only surface deep, and lack the depth to reach the areas that hurt deep down. A study at Children’s Hospital of Wisconsin in Milwaukee showed the LED technology reduced painful inflammation by up to 37 percent.
quote:

According to NASA news, biologists have found that cells exposed to near-infrared light from LEDs, which is energy just outside the visible range, grow 150 to 200 percent faster than cells not stimulated by such light. The light rays increase energy inside cells that speed up the healing process.

Can you sell those or is it patented?

Setting up the patent on this design but it's going through some testing with friends on various issues.

If you want me to build you one, add gmail.com to my user name. We can work out a price via email. It takes about 4 hours for me to fabricate the device.

Testing this on my neck as well.

I’ve had disc issues over the years.

re: Finally finished my homemade multi-radiance LED therapy device.
Ordered some high power LED emitters to try and build one that is around 15W vs the 4.5W device I currently have operating.

Parts will be in by Friday.

It'll use less LEDs, 5 660nm RED and 4 940nm IR, but they all have forward current capabilities of 1-1.5A max. The previous LEDs are 200mA forward current max.

Yours is still coming J!

According to on of the Guru's on photomodulation you have the intensity correct but they flicker. The sun is better.

But most of us work inside and we can't be out sunning ourselves every day.

..and I purposely pulse the LEDs because your body will slowly adapt and you will stop seeing positive effects from a steady illumination.

re: Finally finished my homemade multi-radiance LED therapy device.
The 660nm emitters showed up yesterday.

Man, those frickers are tiny! I thought soldering shite to traditional LEDs sucked. This shite will make me go blind and I already have the LED lamp/magnifying glass combo to work on small stuff.

Is this comparable to whatever Planet Fitness’s Beauty Angel (?) produces?
