Group: Moderator Hero Member Posts: 1737	A little off topic but I think some members may find this project interesting. A mate I met through business networks introduced me to this therapy. I intend to test them for use during meditation as well. Here is the research I have done so far. My NIR LEDs arrived today. ------------------------ 945e4acdfb0547ee98f0f10248515df6.pdf (69.94 kB - downloaded 75 times.)

(aliexpress) I've also bought solderless connectors as I'm looking at the viability for those with a soldering iron to DIY.

Group: Renaissance Man Hero Member Posts: 2752	Hey Guys. Since my stroke I’ve completely lost confidence in my judgement…. The LED strip is 5 M long and labelled 24 Volts. It has been made up from shorter strips, soldered together. Am I correct in thinking that this is the working voltage, no matter the number of LED’s used? I don’t want to burn the $#!t out them….

Cheers Graham. Infrared LEDs have a forward voltage of 1.2 volts at about 20 mA. So you are looking at no less than 20 LEDs in series. (20 x 1.2 = 24 volts. For longevity, I would use a couple more. If you have more than 20, then parallel each 20 (or more LED strips) up. Or you could have 10 (or more) LEDs per strip and work on 12 volts. Again because 12-volt systems can go as high as 14 volts, I would use a couple more LEDs per strip for safety. In practice LEDs have a lot of tolerance for slight overvoltage - but the problem is you can't see infra-red. If you use your smartphone camera, you may be able to detect when they are on and see how "bright" they really are. An afterthought: You could use a visible LED in parallel across two of your infrared LEDS as a visible indicator that your system is working. If the voltage is too low then parallel the visible LED across three infra-red LEDs. « Last Edit: 2024-05-17, 01:39:17 by Aking.21 » --------------------------- Electrostatic induction: Put a 1KW charge on 1 plate of a capacitor.

If you got the 850nm you can see them dimly lit on 12v.

On closer inspection the LED’s are running in parallel with the supply rails, each with its own SMD resistance. We powered up the entire strip and you can see a faint Red glow and feel the heat being generated. Luckily the strip can be cut at 100 mm intervals so we are printing a skull shaped cap to put 200 mm lengths into it. More to come, cheers Grum. --------------------------- Nanny state ?

I've wired mine up but not sure about the hat I've just made some IR glasses. Took an old pair of specs and just stuck a 100mm section across the lenses. Want to see if it improves my vision.

We weren’t sure about the angle of these particular LED’s so opted for a tighter grouping. My major damage is confined to my right hand and arm with a lesser injury to my right leg. From this I concluded that I needed to concentrate on the Parietal lobe?? Luckily I’m seeing the Neurologist later this month so I can confirm this and make any changes later. I have only had one 15 minute session so far, just about to do my second day’s therapy. No change noticed as yet. Cheers Grum. --------------------------- Nanny state ? Left at the gate !!

It gets very annoying this time of year trying to work with my hands. One day when out mowing had it go up to my elbows. I'm pretty healthy otherwise I cured it purely by accident. I was working on my cuticles and fingernails because I discovered I had developed vertical ridges on my fingernails. ie a sign of aging. I also worked on the rest of my fingers. I had suffered from "white finger" for some time - another sign of aging. My first surprise came a couple of winters ago when I had to remove snow from my car. I was surprised when I got inside to discover my hand and fingers a very healthy red colour. Previously I would get in from the cold and bathe my hands in warm water in the sink and suffer excruciating pain as the circulation recovered. (I have told my doctor about this cure.) I would recommend a half hour at a time working on the extremities. So that would be both hands and also toes. The high-frequency massacres the bugs in your body which I assume also includes bacteria sticking to the inside of blood vessels - hence the improvement in circulation. I also use it on my head, which is why I posted here. A healthy blood supply is essential for a healthy body- no matter what your age. I originally bought the device because I watched this video. https://www.youtube.com/watch?v=zHaSDDnWeG4&list=PLZNpOcwXLSyZKHccI_RPCvFn04XbS4GHT&index=39 If you cure your Reynauds, please let us know.

Group: Renaissance Man Hero Member Posts: 2752	It would appear that the 810 nm LED’s are just right for maximum bone penetration. I found some reference to pulsing. Would this unit from eBay be suitable for driving the LED array? Quote from the article…. In a 2007 study of embolic strokes in rabbits, behavioral analysis 48 hours after embolization showed improvement in rabbits treated 6 hours after embolization with pulse wave near infrared light therapy at a frequency of 300 µs at 1 kHz or at a frequency of 2 ms at 100 Hz [12]. Improvement was also seen in those treated at 12 hours post-embolization time with pulse wave near infrared light therapy at a frequency 2 ms at 100 Hz, but no improvement was seen with continuous wave near infrared light therapy at either time point [12]. https://tinyurl.com/2j34hfzr Cheers Graham. --------------------------- Nanny state ?

Group: Tech Wizard Hero Member Posts: 1130	Hi Graham, IF this is the unit you refer to https://www.ebay.co.uk/itm/335338875812/ then its specs say the Load carrying capacity is 30 mA. So in case one string of the series LEDs needs say 24V at 20 mA, then this unit cannot supply more than 1 string's current because of the additional strings come in parallel with the 1st one, demanding 2x 3x 4x 20 mA current from the output of the unit. A solution would be to use a power MOSFET as a separate switch for the LED strings, you put the 4 paralleled strings between the drain pin and the positive 24 V supply rail, the negative rail is connected to the source pin. And the gate-source pins receive the output from the unit but the supply voltage for the unit should be below 20 V to observe the gate-source +/- 20V max specs. But there are MOSFETs types with 25 or 30 V max V_GS if you wish to use such. IT is possible this MOSFET could be built into the box of the unit so a single power supply of 24 V would be needed.

Group: Renaissance Man Hero Member Posts: 2752	Many thanks Gyula. I finally received my LED power supply on Saturday. I decided to go for the 200 W version which covers the 70 W total of my 5 metre string. The number of LED’s is 300. Verpies surmised a 2 ms on period and 8 ms off. With the LED’s running at a 100 Hz pulse frequency? Due to the reasonable price of the unit I will order one, perhaps you’d be willing to aid me further when it arrives? Kind regards.
