Visual ergonomics: light for GOOD vision

Light plays a key role in creating an ergonomically designed workspace. Until now, however, not all managers have had this on their agenda.

Ergonomic workspaces are playing an increasingly important role in today’s working world. Desk-sharing work­stations enable different users to adjust the height of the table, the sitting position and the position of the screen.

Acoustic systems are installed to absorb high levels of sound, and better ventilation and air conditioning systems help to improve the air quality. Lighting, which is also an important part of the workspace economy, often tends, however, to be ignored.

Why do we need “good” light?

The most recent scientific research has revealed that simply having bright light is by no means sufficient to guarantee good vision. This is particularly significant when making a comparison between people of different age groups. As a result of the lens becoming darker with age, a sixty-year-old requires two to two-and-a-half times stronger light than somebody in their mid-twenties in order to achieve comparable vision.

Each individual’s biorhythm influences the requirement for light

Everyone has a personal daily rhythm which is circadian. This means that it is controlled by light and is roughly synchronised with day and night. Modern LED lamps can almost completely reproduce the sunlight’s colour. They have a biological effect on the production of the hormone melatonin and can therefore provide the user with the same biological impulses in enclosed areas as sunlight does in the open air.

In this way, artificial biological light can strengthen the inner clock and thus counteract the consequences of a disturbed circadian rhythm, such as insomnia, irritability and lack of concentration. It ensures a deep and healthy sleep and promotes well-being as well as performance in the workplace.

Planning regulations are too short-sighted

Existing planning regulations for renovated and new buildings contain some gaps. They do not fulfil the require­ments of agile working, as they only include a single source of light which cannot be adapted to individual needs. They do not allow for the fact that each user requires a different light intensity. And they do not take account of the most recent findings about the biological effect of light.

Wellbeing and performance as a result of visual ergonomics

Visual ergonomics offers flexible workplace lighting. In the same way as an office chair can be adapted to a user’s requirements, light can also be flexibly adapted to the situation in the workplace. The level of illumination is as much a part of this as the colour temperature.

All of the lamps from the LUCTRA® range allow the colour and brightness of the light to be adjusted. Depending on the model, the light can be controlled on the touch panel directly on the lamp or automatically via the app. Not only that, the presence and luminosity sensor integrated in LUCTRA® VITAWORK® enables energy savings of up to 80%.


About LUCTRA®:

LUCTRA® is the brand for good light in the office or at home. For this purpose, the table, floor and mobile lamps included in the range provide light which not only illuminates, but also makes people happy, more efficient and simultaneously less tired. This works, because it transmits the right impulses for every situation.

To accomplish this, the professional, biologically effective LED lamp system takes advantage of the latest scientific findings on the effect of light on human beings. It follows the principle of Human Centric Lighting, for short HCL, by focusing on human beings with their personal lighting needs for healthier and more efficient working and living. LUCTRA® light can almost perfectly simulate natural daylight and thus supports the user’s personal inner clock.

LUCTRA® has already received numerous renowned design prizes such as the German Design Award and was brought to market in 2015 by the long-established company DURABLE Hunke & Jochheim GmbH & Co. KG. This company has been dedicated to professional work for almost a century: to its organisation, its processes and its equipment. DURABLE currently employs 700 workers worldwide and has its Head Office in Iserlohn/Germany. All LUCTRA® lamps are assembled manually by expert staff at the LUCTRA® production plant in Kamen (North Rhine-Westphalia, Germany).
