Of the workplace to the rest home, the importance of the dynamic

lighting

Introduction

It makes more than about twenty years than the world of the lighting is conscious of the role which plays the light on our body.

The luminothérapie applied to the seasonal affective disorder in the countries of the Northern Europe is a completely normal prescription today. Other pathologies can be treated (blue light of the premature children) or decreased by a supplementary contribution of light. Lighting designers we are not therapists and without speaking about treatment we can, and I shall tell, we have obligation, to work on the wellbeing of our users.

We do not take into account any more only a level of illumination for the realization of a task but also the whole visual environment in particular to avoid dazzles, reflections and the other nuisances, to us to integrate also the new knowledge of light effect on our body.


Workplace without daylighting

After a first essay of dynamic lighting in our laboratory in 2004, we have, further to a redistribution of premises, to realize a new installation in a place practically without light of day dedicated by our PhD students.

These last ones when they are not only on the ground of their researches or in the analyse laboratories, but calculate, consult, read and draft their thesis in them offices.

It is not because they are young, healthy and for duration limited among us that they do not have to have a decent atmosphere for their work.

Report on the programmed dynamic lighting

I was able to notice, further to a first programming with the reactions of the users the real effects of the variations of illumination as the temperature of colour, with the request, at the end of afternoon, to return to a colder, stronger light, rather similar to that of the beginning of the afternoon (500 lux, 5500 K). Indeed, our students work in a continuous and steady way, from morning till evening, and they felt with the shift of emphasis, as an invitation to return at home,


The case of Alzheimer units

These persons live most often in a reduced space. They can be subject at instants of strong nervousness as unlike a big apathy.

The life in this units follows rules as any community: survey, toilet, lunch, activities, etc.. Bright ambience

can contribute to create a favourable climate.

Lighting training in Alzheimer unit

We were able, by means of the French association of the lighting, at the end of 2007, to go up a training in a rest home wth an Alzheimer unity. Our public, nurse's and nursing aides, has very well reacts to this contribution of knowledge and was able, between two sessions, to realize an audit of the place preparing them to take their place within the committee for reorganization programmed by these spaces.


PropositionsOf these experiments have can retain the following propositions:

• Workshops, provided or not with daylight, need a stimulating environment, a cold lighting adorned us the most adapted. We suggest using fluorescent lamps of type 850 or 950 if the local is without contribution of natural light.

• The places of devoid work totally of daylight, for a prolonged activity, would win to follow our biorhythm by a programmed dynamic lighting. We propose lamps equipped with fluorescent lamps of type 965 and 930 with illumination control and programmation

• The retreat places (included Alzheimer’s disease), where residents are often inactives, would win they to give the possibility to the staff to use the light as a tool to reconstruct a visual environment adapted at the present, stimulating or restful moment. We propose also lamps equipped with fluorescent lamps of type 965 and 927 with local commands, without programmation.

Conclusion

If the programmable dynamic illumination, in certain cases, as the buried workplaces is to envisage, he must be in other cases, as hospital units, manipulated directly par not too much treating, it becomes then a tool in the service of the of the wellbeing of all.
