Guest guest Posted December 2, 2003 Report Share Posted December 2, 2003 I had a remarkable first try with the Infra-Red (IR) side of my Light Therapy unit. For about 2-3 years now I have been favouring a rotator- cuff injury to my left shoulder. A real deep pain...that severely affected my golf swing!! Thought I would have to live with it, since nothing I tried ever gave me relief. Last night I placed the IR side to the shoulder area, set Nogier frequency B (584Hz), and left it for 20 minutes. After that single treatment, I got up and moved my arm around. Hmmm I thought, feels pretty good. Actually, it feels fantastic. I had a good night's sleep and after waking I tried moving the shoulder around. Much to my total amazement, I had zero pain and full mobility! I was shocked. Actually, I still am. It is the most remarkable healing I have ever been witness to. And this is only with one treatment. I will continue to treat over the next week and also treat other problematic areas that have not responded to other therapies. I am going to the golf driving range today to see how the shoulder holds up under stress. But from what I can tell right now, I can say that I am 99% healed. Wow.

Guest guest Posted December 2, 2003 Report Share Posted December 2, 2003 Russ, what light therapy unit are you referring to? Have you developed one? Or is this one we can buy? ...Dean On Tuesday, December 2, 2003, at 08:07 AM, sotainstruments wrote: > I had a remarkable first try with the Infra-Red (IR) side of my Light > Therapy unit.

Guest guest Posted December 2, 2003 Report Share Posted December 2, 2003 Hi Dean, This is a new prototype unit that I am designing. I hope to have it available in few months. Cheers!

Guest guest Posted December 2, 2003 Report Share Posted December 2, 2003 Hi: Some of you may be interested in the following. For LEDs of kinds : <www.gilway.com> <www.eLumexLEDs.com> Title: About LED's,Candelas and Watts. I shall make some statements, they are at the best of my knowledge, today. Of course comments and corrections are most welcome. Visible LED's are usually specified in Candela units. This units are weighted to the human eye response. When LED's are used for tissue irradiation the important Item is the forward (Light going forward, not in all directions) radiant power, expressed in Watts (or milliwatts) and since Watts x seconds = to Joules, the dose should be expressed in Joules (watts-second). To obtain the radiant power from LED manufacturers has proven rather difficult. So here are some numbers: (Values are approximations) MGMicro LED clusters (from used traffic signals) Red probably 660nm, At 1.8 volts, 20 mA, 600 mCd, 0.65 mW 2.0 45 1000 1.37 Approximates Gilway E168 Green probably 565 nm At 2.2 Volts , 20mA, 300 mCd, 0.064 mW 2.5 45 600 0.17 Approximates Gilway E166 As can be seen from the above numbers although the red and the green have the same " brightness " (600 mCd) the power emitted by the red is 10 times that of the green. This relationship approx. holds for all reds Vs green LED's. Therefore the use of the candela measure can be misleading. Also LED's with wider view angles (2 Omega1/2) and the same Candela have more power output than narrower ones. Infrared LED's are usually specified in milliwatts per steradian . A steradian is a solid angle (3D's) which having its vertex at the center of the sphere, cuts off a spherical surface area equal to the square of the sphere radius. So in a 1 meter radius sphere an angle of 1 steradian will encircle an area of one square meter. Here care must be exercised, when the specs said an LED has a 20 mW/sr. It does not mean that if the power is measured in its center steradian angle it will be 20 mW's, The power density will be equal to 20 mW/sr only in the center one hundred of a steradian. So once again the thing that counts is: The total radiant power emitted forward. Example: Giway IR LED # E24 specified at 20 mw/sr (typical) has the following total power: At 1.4 Volts, 20 mA, 3.20 mW at zero distance from LED face. 2.54 mW at 1.0 cm (into a 1cm detector) 1.21 mW at 2.5 cm (into a 1cm detector) However if the power in the center 0.01 sr is measured and then is multiplied by 100 it will equal to 20mW/sr. In my experience irradiation with IR(880) and Red (660nm) clusters seems to help in a number of maladies. To build a powerful IR (72 LED's) cluster a kit can be purchased from the maker <www.dalewheat.com> or from BGMicro. <www.bgmicro.com> Complete kit $25.95 part # LED1069, Assembled and tested $35.95 LED 1070 . A weather resistant enclosed version for $59.95. The PCB part # LED1070, $9.95 can be used to built a RED version using Gilway #E184 LED's (660nm, 2000 mCd, min., 3500 mCd max.) Its power output at the led face is: At 1.85 V, 20 mA, 2.0 mW 2.00 V, 36 mA 3.5 mW 2.30 V, 60 mA 5.3 mW For continuous wave Operation, 200 Ohms resistors can be used. For pulsed operation the circuit provide by Walter Cook at <www.seanet.com/~waltc/page43.htm> is very useful. For extensive information on LED's and Laser Diodes, use and dosages see : Therapeutic Lasers Theory and Practice, by G. Baxter,. Churchill Livingstone, Publisher. Last Comment:, Remember that: Power Density = Irradiance = Total Incident Power / Area. [Watts / cm^2] Radiant Exposure = Energy Density = Total Incident Energy / Area. [Joules / cm^2] = [Watts-sec/cm^2] Radiant Exposure Also is equal to: Total Power Density x Total Time of Irradiation [Watts/cm^2 x Seconds] Walter's schematic produces a frequency of 7 Hz at 50% duty cycle. Baxter states that a 4Hz frequency decreases sensitivity to pain immediately, Walter's circuit can be easily altered by changing a couple of components .

Guest guest Posted December 3, 2003 Report Share Posted December 3, 2003 Hey , Wow you are a great wealth of information!! Perhaps I can pick away at your brain? BTW thanks again for the technical info on the gauss calculation. :>) I would like to calculate the Joules delivered by my LED unit. The 660nm LEDs output about 4,000 mcd each. View angle (2 Theta 1/2*) = 16, forward voltage ~2.1 Volts and recommended current drive is 20mA. I am driving them at close to 20mA (constant-current). It seems the power output is close to the example you showed here at 2.0mW. Now, I have a cluster of 60 Red LEDs spaced about 0.2 " apart. The IR LEDs are 880nm, 1.3Volts, 20mA, View Angle = 20, and output is 30mW/Sr. I am running them at 20mA as well. The cluster is also 0.2 " spacing and there are 52 LEDs. Would the mW/cm2 rating take into account the cluster of LEDs or is it referring to one LED only? I'm new to all this light stuff! What's your take on this?

Guest guest Posted December 28, 2003 Report Share Posted December 28, 2003 Well look on ebay you can get a circuit board tha will hold 72 leds and you can get a variety of leds for real cheap on other auctions. I recently bought 200 white leds on ebay for about 40 bucks that included the shipping from China which was about 20 of it. And they got here real fast. Also got 100 rea bright red leds for about 17 bucks and put it in one of the boards the hald 72 leds. man is it bright. cant look at it. run off 12 volts I just use a wall wart to run it. I think thu board runs arounh 7 bucks and the leds were 17 so tha makes 24 bucks plus a few resistor.
