Abstract
What is BS EN 4731 - LED luminaires about ?
BS EN 4731 is an international standard that defines a measure for the spectral quality of LED luminaires in terms of the ratio of the amount of visual light emitted by the luminaire versus the amount effective for charging photoluminescent products contained in that spectrum. Fulfilment of BS EN 4731 by a LED luminaire will ensure general compatibility of the luminaire with photoluminescent marking systems. BS EN 4731 alone does not provide any means of compliance to fulfil any airworthiness requirements. For a specific aircraft installation, the spectral power distribution and illuminance at the photoluminescent marking systems are relevant.
