Abstract

Lighting technology is advancing far faster than the metrics used to

define lighting and we have a rare opportunity to redefine lighting

for the better. In this talk we will dig deep into existing lighting

metrics and regulations and question if they need to change to be

more human centric.

The problems lighting industry metrics and regulations have caused in artificially

lit environments.

How we ‘unlearned’ the importance of natural light.

Why and how some widely used metrics such as UGR (unified glare rating) may

no longer be fit for purpose when using LEDs instead of legacy light sources.

Why designing luminaires for with LEDs requires new optical approaches and

form factors.

Insight into why the lighting industry needs to go beyond technological

improvement and put the human at the centre of lighting design.
