Application of IEC 62471 for the assessment of blue light hazard to light sources and luminaires*

This Technical Report brings clarification and guidance concerning the assessment of blue*light hazard of all lighting products which have the main emission in the visible spectrum*(380 nm to 780 nm). By optical and spectral calculations, it is shown what the photobiological*safety measurements as described in IEC 62471 tell us about the product and, if this product*is intended to be a component in a higher level lighting product, how this information can be*transferred from the component product (e.g. the LED package, the LED module, or the lamp)*to the higher level lighting product (e.g. the luminaire).*A summary of recommendations to assist the consistent application of IEC 62471 to light*sources and luminaires for the assessment of blue light hazard is given in Annex C.*NOTE It is expected that HID and LED product safety standards will make reference to this Technical Report.
