Hi fredericjulien13,

to calculate the output of 5 mm LEDS for cm2 you take the output of one LED and
multiply it by 4 because you get 4 LEDs in a Square Centimeter. So if the LED
puts out say 14 mw that would be 56 mw.

the only way to get that much out of a RED 5 mm LED is to get to the high power
metal ones or LUxeon type. they make nice power arrays with multiple LEDs on a
metal back that can put out out tons of light.

Look for Luxeon Floods
http://www.google.com/search?hl=en&q=Luxeon+Floods&btnG=Google+Search

The LED units I make put out about 25 mw per cm2 for the 660 red. I can get
stronger ones for the 6235 or 630nm




Take care,
  V

Hi Paul,

those are nice LEDs I have some of them. but the 500 mw figure is not the output
of the LEDs that is how much energy they can dissipate basically and does not
indicate their output. I think lots of manufacturers might use that figure to
tell the output of their LEDs.
At the most those 10 mm LEDS might put out 30 mw, but probably more like 15 to
20.

For red 5 mm LEDs you might get around 6 to 7 mw output, blue ones con put out
around 14 mw, infrared ones at 880 nm put out around 6 and ones around 850 can
put out about 12 to 14 mw

So if you see figures up there in the triple digits for 5mm LED output they are
bogus. A plastic LED can't put out that much without burning up.

I send most of the LEDS I use to somebody that has a machine that measures the
actual output of the light. And those are the figures I get back.

So when you read various websites with them telling you they have high figures
for the output you better check close what numbers they are publishing. the
dissipation figure is not the output, that is how much energy the LED can
dissipate in heat and light without it burning up. And if you put a bunch of
LEDs together in an array the figure changes because now to dissipate that much
you have to put fans on there to remove the heat. Or run them for only a short
amount of time.

  V

hello,

I need to create a device for phototherapy for skin treatment.
I've seen many on internet but the values given in technical
caracteristics are strange and seems unreachable like in the siloueth
tone device: http://www.silhouet-tone.com/product/specialized/soli-tone-
2500/soli-tone1.html or the Omnilux revice:
http://www.phototherapeutics.co.uk/index.asp?AccessID=&sectionID=15

they give an output of 105 mW/cm2 in red 630 nm ? but, it seems that
they use 5mm LED but even with the brightest I've found I connot reach
that level. to reach such level I have to use High power LEd like
LUXEON K2 but the heat dissipation is a real problem.

did someone know what kind of LED are used for those application.

Hi Saralou,

Most likely you have the 470 nm wavelegth on that panel.

no way to measure it without some expensive equipment.

Blue light destroys antibiotic-resistant staph infection


www.chinaview.cn 2009-01-30 06:31:44 Print

WASHINGTON, Jan. 29 (Xinhua) -- Two common strains of methicillin-resistant Staphylococcus aureus, commonly known as MRSA, were virtually eradicated in the laboratory after being exposed to a wavelength of blue light, according to a paper published online on Thursday ahead of print in Photomedicine and Laser Surgery.

Antibiotic-resistant bacterial infections represent an important and increasing public health threat. At present, fewer than 5 percent of staphylococcal strains are susceptible to penicillin, while approximately 40 percent to 50 percent of Staph aureus isolated have developed resistance to newer semisynthetic antibiotics such as methicillin as well.

Researchers from the New York Institute of Technology had previously demonstrated that a process called photo-irradiation using 405-nm light destroys MRSA strains grown in culture. In the current study, the authors exposed bacterial colonies of MRSA to various doses of 470-nm light, which emits no UV radiation.

The two MRSA populations studied -- the US-300 strain of CA-MRSA and the IS-853 strain of HA-MRSA -- represent prominent community-acquired and hospital-acquired strains, respectively.

The authors report that the higher the dose of 470-nm blue light, the more bacteria were killed. High-dose photo-irradiation was able to destroy 90.4 percent of the US-300 colonies and the IS-853 colonies. The effectiveness of blue light in vitro suggests that it should also be effective in human cases of MRSA infection, and particularly in cutaneous and subcutaneous infections.

Blue light destroys antibiotic-resistant staph infection

     WASHINGTON, Jan. 29 (Xinhua) -- Two common strains of methicillin-resistant

Jaap, in the meantime what about looking on Bevan Potter's site for Cansema?
Naturally, it is sold for animals, but I can attest to the fact that it
works on skin cancer in humans also.
http://www.centreforce.com/
Bevan Potter himself had skin cancer cured by Cansema after repeated
operations on his head failed to eliminate it.  There are photos on a link
from the left hand margin "My Photos".
I got our Cansema from a vet in WA, but it was made in Qld and I think
originated from Centreforce.

Hi stevewonder5000,

All my arrays are not pulsed, they are steady on.

I am aware of the various frequencies to pulse LEDs for various healing modes.
there are the Nogier frequencies for example.

I have looked into that and did offer a pulser for my units in the past. but
many people could not get it to work with their computers. so I discontinued it.
will be offering it again in the future when I get the circuit modified a little
to work with more computers.

Pulsing the LEDS has a different effect than the steady on LEDS. there is place
for both of them I chose the steady on because you get more light in a shorter
time. that is in itself one way that the LEDS heal, the pulsing mode triggers
something else entirely, and can be done with sound also.


Take care,
  V

Dear V.
I am urgently interested in your 660 nm led array. We already use the vastly
overpriced
Healthlight.com led system but found out that it is not 660nm. That wavelength
appears to
be the best one to treat skin-cancer ( on our pet we intend ) in combination
with a PDT
sensitizing cream. Here in Australia no one knows the real thing so we have to
experiment.
The skin-cancer on our cat is to complicated for surgery being in and around her
ear. Our
only question to you is : in the wound / skin treatment you know about ... how
close does
the LED array have to be for good result ... or better said how  far before not
effective
anymore., and how deep does the light penetrate?
Since your 96 LEDs array is a square box it would be impossible to be at the
same distance of
every part of the cat's skull. Is a flexible pad an option?

Hi zanaglen,

Well I was going to make a website that covers all that. basically its all the
things on the website plus there are smaller versions of those with only 56 LEDs
in them. then I have a variety of larger panels both flexing and rigid panels,
with either or both 660 red and 880 infrared. ranging from 500 LEDs up to 2700
LEDs or more, I also make color therapy panels with 6 colors, and 3 color panels
and 12 color ones. I have made a variety of custom panels for people. Also made
a few custom panels for science outfits for research, and ones for people with
Rosacea.

for some companies I make special exclusive items one is a Dentaray. which is an
LED for use on the teeth or gums and single LED wand for use in frequency
machines specifically designed for the machine. And one doctor ordered a bunch
of hand held mixed 660/880 units for his website product line.

So I do some wholesale and some retail.

Take care,
  V

Hi A,

I do not think so because he IR penetrates quite deep. you can put it on the
side of your head for example and it will still get through to the eye. it can
go right through bone. So even if you look up or to the side the IR will still
go right into the eye through the side of the eyeball if its not covered with
foil. the good part is that it has a narrow beam so you can be quite precise on
where it goes, for example shining it right below the eye with the edge of the
array at a downward slight angle will miss the eye itself., it comes out in a
pretty straight line out the front so even being off angle a bit from the beam
and its gone. Let me know if this helps

Take care,
  V

Hi Cyteen,

Yes but they are made to protect from UV ( ultraviolet) and the LEDS put out IR
(infrared) I don't think the will protect unless you add the foil. Because Foil
blocks Infrared which may go right through the UV filter they put on those.

Hi realdoggymouse,

Well the RED led can speed up hearing by twice if you can get the light to the
area. And it does it by stimulating the cells to produce  more ATP which is
their energy source.

the infrared 880 increases circulation.

I can't say if your conditions would be helped or not as I am not a doctor.

Take care,
  V

Hi realdoggymouse,

Well it depends on the color of the LED, the 660 LED can go about 1/2 to 3/4
inches. the infrared 880 can go up to 3 inches.

But then a blue LED has almost no penetration. So it depends on what laser you
are talking about. What color and what power level.

Thanks, does this mean the LED can penetrate the skin like a laser?
I'm confused because many of the studies talk about lasers.  I'm
curious if the LED can heal tendinopathy or vascular problems.
Thanks again.

Hi realdoggymouse,

Well there are a few differences, One is that a laser can operate at a much
higher power level than an LED, does not mean that all of them do however, most
small lasers put out 5mw or less, LEDs can do mare than that. A laser puts all
the light on one small spot so the concentration is much greater, but then if
you have  treat a large area it may take a long time. LED can cover a large area
at once. You can get LED units much more readily than laser units.
Leds are safer there is no over doing it in most cases. with a laser you have to
know how much time to use it so you don't over do it.
A strong laser can be expensive compared to an LED unit also.
LED units can be made in more variety of colors for various applications than
lasers can.
So it all depends on what you want to do and how much you want to spend. If you
have a serious inner ear problem for example a laser may be best due to its
ability to keep the light focused and higher power, but if you want to sooth
sore muscles then an LED unit will probably work better.
It all comes down to the right tool for the right job.

Oh and a laser has a more precise frequency than an LED, a narrower range.
