Abstract:
The publication of IEC 62471 "Photobiological Safety of Lamps and Lamp Systems" heralded a new framework for the evaluation of the photobiological safety of non-laser sources of optical radiation. In Europe, a legal impetus was provided through its’ harmonisation to the EU Low Voltage Directive. Issues with the application of IEC 62471, in the case of sources intended for lighting applications, have led to the development of a new approach for these products through the revision of lamp and luminaire standards to provide a consideration of photobiological safety and the implementation of IEC/TR 62778 where required.
