RE: [LEDeffects] wich type of LED necessary for phototherapy treatment for skin rejuvenation

Here’s a link for 10mm leds they are 130,000mcd, 500mw and at 620nm. It’s an ebay store called shop4leds. I bought some of these and they are super bright.

Subject: [LEDeffects] wich type of LED necessary for phototherapy treatment for skin rejuvenation

 

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.

best regards

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...

Hi Paul, Yeah and the spec sheets are often not correct. typically some manufactures over state their specs by several factors in some cases, particularly some...

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...
