Introduction
Higher luminous flux and improved efficiency mean that LEDs are being increasingly used as light sources in luminaires. To ensure that they are used safely, safety standards have been developed, as for conventional light sources. One aspect of light source safety is photobiological safety.
This is concerned, for example, with the impact that radiation emitted by a light source has on the human eye. LED light sources are no different from other light sources in this respect but were covered in the past by standards developed for lasers. That situation has now been rectified in the case of LED light sources for general lighting service, i.e. it has been technically and normatively acknowledged that LED light sources of this kind have no relationship with lasers.
Remark This paper looks at the legal basis and conformity assessment for line-voltage operated luminaires for general lighting service. Comparable safety requirements exist for luminaires for special purposes or with operating voltages outside the scope of the Low Voltage Directive but the special – at times differing – regulations and conformity assessment procedures relating to them are not examined here.
