How to use human centric knowledge to your advantage

How can the new science knowledge on circadian rhythms be best translated into new products and real health and wellbeing benefits?

Human centric lighting and circadian rhythms have become much more common terms over the period of the last year. But, despite the rise in awareness, not everyone knows how best to use this new knowledge when designing new lighting fixtures. At Lux’s upcoming Lighting Fixture Design Conference we intend to close the gap between know-how and real-world application. 

Elliet Jones and Graham Dean of Helvar will discuss how the science can be best translated into new products and real health and wellbeing benefits to a building’s future occupants.

Just last month Lux caught up with Professor Russell Foster who is credited with discovering light sensitive ganglion cells in the retina of the eye, which influence the body’s internal clock.

Professor Foster told Lux that the lighting industry needs to take a much more ‘dynamic’ approach to lighting workplaces and needs to work in a more determined fashion to define what a space is being used for and then light it accordingly.

‘If you a designing spaces where people need to be particularly alert, you could install blue-enriched light for that purpose.’

The research is not only pertinent to the morning, but can also be used to improve rest at night. This is certainly the case on hospital wards, which are often lit throughout the night.

‘If you go into an intensive care unit it is kept constantly lit. This means your internal clock cannot lock onto a signal meaning it will start to drift and physiology will start to fall apart. All in people that already vulnerable.’

Foster went on to advise the industry to adopt a much more nuanced attitude towards the research.

‘We do now know that the rods and cones in the eye can modulate the light sensitive ganglion cells. So we need to see some more research and I don’t think we should just run in and put blue lights all over the place.’

Rather than simply sticking to a blue light good, red light bad maxim Professor Foster, suggested that more dynamism and research is instead required.

  • The LED revolution has concluded, prices are falling and the industry’s attention is turning to the digital world, to the internet of things and smart cities. Lux’s curated and timely   Lighting Fixture Design conference  will help lighting industry professionals to map out a strategy for the new digital lighting world and help them to take advantage of the changing scene. The event will take place in London on the 21 – 22 of February 2017 at the Cavendish Centre .
