ma sta certificazione la daranno per qualche motivo immagino... non si tratta solo di non guardare diretto il led...
CREE, che certifica i suoi led, nel documento
http://www.cree.com/products/pdf/XLamp_EyeSafety.pdf
scrive
"All light sources have the potential to be harmful to both the skin and the eyes through UV, blue light (410
0 nm) and IR emission. Independent photobiological testing of Cree visible light LED lamps has confirmed that the only health risk of visible light LED lamps significant enough to warrant advisory is viewing blue light with the eyes. LED lamps that emit blue light may be called multiple names, such as Blue, Royal Blue or Dental Blue. In addition, many white LED lamps, including Cree’s, are based on blue LED die and contain significant blue light content. Therefore, Cree has tested its Royal Blue, Blue and White LED lamps for eye safety. Cree’s testing to date indicates that Royal Blue and Blue (450
5 nm dominant wavelength) LED lamps pose a higher eye safety hazard than White LED lamps. Other colors of LED lamps, such as Green or Red, do not pose a defined eye safety risk. Regardless of LED color, Cree advises users not to look directly at any LED lamp."
quindi, non guardando direttamente i CREE dovremmo stare tranquilli, ma possiamo dire lo stesso di altri prodotti privi di certificazione?
Ad esempio, voi sapete se Satisled certifica i suoi prodotti?
