Photobiological Safety of Lamps and Lamp Systems (IEC/EN 62471) for LEDs

Evaluating the photobiological safety of lamps and lamp systems, including LEDs, to IEC/EN 62471 is a legal requirement for lighting products sold in Europe. Photobiological testing relates to the optical radiation effects of LED and traditional lighting on human eyes. As LEDs become widely used, assessment of the unique “blue light” hazard is critical. The Photobiological Safety of Lamps and Lamp Systems (IEC/EN 62471) for LED Lighting white paper provides an overview of exposure limits, measurement techniques, classification of hazards, and manufacturer obligations including labeling requirements.
