IEC TR 62778
Application of IEC 62471 for the assessment of blue light hazard to light sources and luminaires
|Publication Date:||1 June 2014|
|ICS Code (Lamps and related equipment):||29.140|
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.
