LED lighting as a strategy for a healthy living environment

Technology can be used to make lighting more energy-efficient and have longer life-spans. These form important elements for reducing the impact on the environment, although much more is possible. Lighting could also contribute towards a more sustainable living environment. These are interesting strategic directions for lighting manufacturers. Using LEDs in combination with other technologies indeed creates a whole range of possibilities.

Sustainability itself doesn't sell. A product that consumes less and lasts longer is also not going to easily sell itself. Therefore more is needed. Via a number of blogs we are seeking out potential strategies that could contribute to linking sustainability strategies with healthy business. We always use examples.   

Lighting and well-being

The influence of lighting on personal well-being is a possible strategy. Light has visual (sunlight), emotional (shape and colour of the light), as well as a biological (IR and UV light and dynamically visible light) impact on people. Also indoors. Lighting manufacturers can respond to this with their products. Though the question arising here concerns the ways in which lighting can actually improve our living environment. 

By way of open innovation, manufacturers Fairwind, Artelight and Luceinvento came up with the idea of tackling the issue of air quality for interiors. Air quality for interior spaces is extremely important, certainly where such spaces are concerned with healthcare. Combined solutions involving lighting could be very interesting for these sectors. The requirements include low maintenance, good lighting quality and the removal of germs. 

They are developing a method where both lighting and air quality are addressed together with a 'hygienizing' lamp. Fairwind already produces customised lighting solutions that harmonise with their surroundings, moreover, these solutions can also adapt to specific circumstances and times of day. The LEDs used for the lighting mimic natural light as far as possible. 

Control over lighting and air

New functionality for lighting that meets the requirements found in the health sector could involve purifying the ambient air via photocatalysis using TiO2 and UV LEDs, combined with LEDs that radiate light in the visible spectrum. UV waves carry more energy than visible light waves. The catalyser absorbs only part of the wave lengths. Once the TiO catalyser is stimulated, it creates hydroxyl radicals and very fine oxygen ions. This reaction breaks down contaminating molecules into harmless CO2 and water. This is how the air is purified.



Such lighting solutions represent simple applications with minimum maintenance, which simultaneously support well-being by controlling several ambient elements, namely light and air. Technological advancements guarantee longer service life, higher efficiency and cheaper LED equipment that is generally smaller thanks to the more compact dimensions of light fittings. 

The 'H lamp' is currently still being tested, thought it is expected to be put on the market at the beginning of 2016.

Possible applications for such lighting are initially hospitals, doctor and dentist surgeries and waiting rooms, with day nurseries for children being another one of the possibilities. 

A forthcoming blog will illustrate that it is also possible to create a sustainability strategy with 'interconnected products'. 

The first of the LED Events takes place in the Elewijt Center (Elewijt - Zemst) on 2 December when Thomas Vandenhaute from Sirris will be making a presentation titled, ‘The role of technology in the sustainability strategies of the lighting sector'. Further examples and a strategic framework will be presented.
