Working without sitting in an awkward position: the ideal desk lamp

DIn many cases, nature has succeeded quite well in allowing the creatures on this planet to cope more or less. Bats for example have a clever echolocation system to guide them across distances of up to 300 metres ahead. Moles live underground, are blind and deaf. But they have two nostrils for smelling in stereo, and so they sniff out both food and danger. The most important sensory organ in humans is the eyes, with around 80% of sensual impressions being visibly perceived. Working at a desk is a particular challenge for the eyes. In Germany, millions of people work in an office. It is hugely important for them to be equipped with adequate desk lighting, not just to sustain their powers of vision also to prevent them from assuming a constrained posture. While the lighting does not impact directly on the musculoskeletal system, it does have an influence consisting of so-called asthenopic effects (asthenopia = eye strain). Ideal lighting conditions therefore play a major role in ensuring that we work in a position that is not awkward for the body, which also has a positive effect on our well-being and work performance.

Our eyes need adequate brightness in order to see things properly. Incoming light rays pass through the cornea, pupil and vitreous body until they meet the retina. The retina contains 120 million light-sensitive rods and seven million colour-sensitive cones. These photoreceptors create an image standing on its head which then goes through neuron processing to obtain a realistic impression. In other words, the brain puts the image back from its head onto its feet.

But what happens when the desk lamp fails to comply with the requirements for modern office workplaces? It may be too bright or too dark, it may generate shadows or reflections. As a result, we tend to screw our eyes up, push pieces of paper back and forth to find some position in which we can more-or-less read them, start adjusting the computer screen or - even worse - twist our necks and end up sitting in an awkward position.

High-powered LED lamps

To avoid constrained posture and to make desk work as pleasant as possible for the eyes, the back, the spinal column and the neck, clever people have been giving lots of thought to the whole problem and developed a clever desk lighting system. The result: high-powered LED lamps. They generate a homogeneous, extensive working light and their illuminance can be adapted to the specific task in hand. Special reflectors permit glare-free working. The lamps provide a good contrast between the computer screen and the surroundings, thus permitting fatigue-free, back-friendly working.

The desk lamps have a user-friendly, easy-to-use articulated design that is easy to clean and adapts perfectly to the working environment in an office and at VDU workplaces. They are naturally flickerfree with fully variable dimming. Specially adapted colour temperatures also permit the best possible contrast sensitivity. All these advantages help to prevent a constrained posture which would be harmful to the back. This reduces the work pressure and the eyes don't tire so quickly with far less muscular tension. The illuminance at VDU workplaces should normally be around 500 lux..


Minimum requirements:

  • Statutory safety regulations must be met.
  • Special normative requirements must also be heeded.
  • It must be easy to adjust the arm with the articulation system.
  • The lamp must be easy to clean.
  • It must be possible to adapt the lamp to the working environment in the office and to the VDU workplace.
  • The lamp must satisfy the requirements for the specific task in hand,
    for example by:
    • adjustment of the illuminance
    • appropriate colour temperatures
    • homogeneous illumination
    • avoiding reflections and reflected glare
    • soft adjustment of illuminance
    • flickerfree, high-powered lamps
    • fully variable dimming
  • Optimised visual conditions avoid constrained posture - lighting must be surface-directed and homogeneous with minimum glare, for example with
    • fine adjustment of the lamp head and articulation system for near vision (viewing distance: 40-80 cm)
    • fixtures that make it possible to point the lighting to the required field of vision
    • troublefree handling as would be expected

Also appropriate:

Lamps with LED technology

  • low energy requirements
  • low heating-up of the surfaces
