Day and night, you sometimes spend hours at your desk without stopping to work. This is why artificial light is very important in our ability to maintain all of its concentration. Bulb, orientation, brightness and lamp model, here’s how to stay efficient at work.
inadequate lighting of the work space can lead to fatigue and eye irritation as well as headaches. But with a good level of lighting, the number of errors and accidents decreases and visual fatigue is reduced ”. All the more reason to detail what good lighting in an office area is.
What you should know about lighting an office area
In an office, as in any living room, priority must obviously be given to natural lighting . But even by placing your work space near a window, it will have to remain functional when the weather is gloomy or when night falls early.
Before dwelling on the quality of this artificial lighting, it is advisable to make a point on the number and the type of lamps which it is advised to install. Because it will first be a question of not being satisfied with a single desk lamp , because it would generate contrasts with the surrounding darkness which would quickly tire your eyes.
Multiplying the light sources is therefore absolutely essential to allow variations in use depending on the hours of the day and the desired working conditions. Because light must not only ensure visual comfort, but also create an atmosphere. To stimulate alertness and activity, we will seek a high degree of brightness. And for a more intimate atmosphere, conducive to reflection, we will opt instead for a soft and subdued light.
Ideal lighting should therefore include at least two desk lamps, but also at least one ceiling lamp with uniform light distribution. But if the number of lamps is important, their location, their orientation and the quality of the light they diffuse are also. Especially since these other precautions may vary significantly depending on other more individual criteria, such as the type of activity practiced, the interior design conditions, but also your own personality.
If your office lighting should be chosen to suit your needs, it must finally be scalable and can be adjusted to suit all situations. Dimmers, beam tilt, articulated arm, it’s up to the light to adapt to you, and not the other way around!
What orientation for a desk lamp?
The first question to ask is to place and orient a lamp. Are you right or left handed? If you are right-handed, place your desk lamp to your left to limit the gray areas when you write. And if you’re left-handed, do the exact opposite. Then direct the light flow towards the center of the work area while preventing it from crossing your field of vision.
Do you work on a computer? If this is the case, you will need to install a low intensity lamp near, on the side or back of the device, to avoid tiring your eyes. In the ceiling , avoid spots and prefer a uniform light scattering suspension.
In any case, always pay attention to direct glare and do not direct any light beam into your line of vision. Finally, glare can also be annoying: therefore avoid lacquered office surfaces such as shiny work rugs and choose mat coverings instead.
What light intensity?
To answer this question, you have to start by looking at the type of work you need to do. The more it involves precision and thoroughness, the greater the light intensity required.In most situations, the office lighting for a workstation must ensure a minimum of 250 lux and be able to be raised to 500 lux according to need. But certain particularly precise works, such as watchmaking for example, may require an increase of more than 1000 lux.
Care should also be taken to avoid excessively large differences between the level of lighting in the work area and its environment. Because too large a gap would cause certain fatigue, by urging the eyes to adapt to this difference in intensity.
What bulb for a desk lamp?
This is the sinews of war when it comes to artificial light, a good bulb must above all limit glare. Instead of the classic LEDs which give off annoying blue light for working, prefer white light models or halogen bulbs for the quality of light given off. Because you should know that the color of a light source has a huge influence on visual comfort. Warm shades (yellow, orange) have a color temperature below 3300 ° K when cold shades (white, blue) rise above 5300 ° K.
According to the office quality of life observatory: “ For office activities, we would rather recommend bulbs with a color temperature between 3000 and 4000 ° K. »In general, powerful lighting (greater than 500lux) should have cold tones while weak lighting (less than 300lux) should rather provide warm tints. Finally, avoid placing a compact fluorescent bulb within 30 cm of you.
What model of lamp for the office?
Beyond its design, a desk lamp must above all be practical, efficient and functional. Being able to direct but also to move the luminous flux is therefore essential to any good work light. Articulated arm, swivel head, or even retractable lampshade, it is a question of being able to be accompanied by a beam of light precisely targeted on all the work area.
Finally, if it is often recommended to opt for luminaires with dimmers to adapt your visual comfort, this is particularly true for desk lamps. On the ceiling, a pendant lamp or a high floor lamp will be less aggressive than spotlights and must above all be dressed so as to diffuse the light evenly.
What about your screens?
Unless there is technological resistance, most offices today are equipped with at least one screen. Laptop or desktop computers, televisions, or touch pads, these new work supports have a special relationship with light. Because if they are more readable in the dark, it is not a question of consulting them in the dark! It is therefore advisable to limit the reflections because they reduce the contrasts and therefore the readability of these screens. We will therefore move them a little away from natural or artificial lights and we will arrange them perpendicular to them.
Finally despite their name, so-called fixed screens can still pivot slightly to adapt to the direction of light depending on the time of day. It suffices to install them on a support or a turntable specially designed for this purpose
