CIE 205 2013 Edition, January 1, 2013 REVIEW OF LIGHTING QUALITY MEASURES FOR INTERIOR LIGHTING WITH LED LIGHTING SYSTEMS
More info
Description / Abstract:
The work of the Technical Committee has focused on the
application of commercial interior LED lighting systems. Therefore,
the quality of the lighting solution is considered, not the
intrinsic quality of the product.
Lighting practice and the majority of existing lighting quality measures focus on visual performance and avoiding visual discomfort. Nonetheless, a high quality lighting installation goes beyond visibility of the task and includes visual appearance of the space (e.g. Veitch et al. 2007 and work done within TC 3-34 Protocols for Describing Lighting and TC 3-45 Luminance Based Design Approach). As the use of LED lighting systems can have a significant effect on the appearance of the room, this aspect has also been included in the Technical Committee's work.
The work of this Technical Committee did not include the review of photobiological safety requirements for LED lighting solutions. Although the committee is aware of the fact that LEDs, being bright, point-like sources, pose a potential risk for eye injury from excessive irradiation, this topic is addressed in IEC 62471/CIE S 009/E:2002 (IEC 2002) and TC 6-55 Photobiological Safety of LEDs.
