Before we can respond to the details, it is important to know the difference between indirect and direct light. Indirect lighting Reflecting on the walls and ceilings and thereby creates a uniform light distribution that illuminates the room without hard shadows or glare effects. This ensures a soft, inviting atmosphere. Direct lighting In contrast, the light focuses on certain work areas - ideal for tasks that require a high concentration. A combination of both types of lighting enables flexible adaptation to different activities and preferences. However, the most effective light source is even more important: that daylight. Natural light from the outside increases the general illuminance in the room and has a positive impact on our mood and health. Maxify daylight by Desks Set up near windows and ensures a good distribution of the light, so it should always be a priority when planning the office lighting. Because the sun does not work reliably at the desk every day, artificial lighting is required that reliably steps in - and all the important ones light technology quality features fulfilled.

Lighting level
The illuminance, measured in Lux, indicates how bright an area is illuminated. For office workstations, a value of at least 500 lux is recommended to relieve the eyes and improve the readability in the workplace. Higher values ​​of up to 1,000 lux can additionally promote concentration and well -being - especially with detailed tasks. This recommended illuminance does not have to be reached in the entire room. It is sufficient if it is available directly at the workplace. In the ambient area - i.e. in the rest of the room - the light intensity should not be below 300 lux, so that the environment remains pleasant and eye -friendly. In the case of partial surface -related lighting, such as a desk lamp, an area of ​​at least 60 × 60 cm with around 750 lux should be illuminated. Ideal if the light is to be flexibly adapted to different tasks or individual eyesight.

Luminance density distribution
The light density describes how bright individual surfaces appear in the field of vision - and thus how pleasant the light is for the eye. Luminaire density conditions of about 3: 1 between the work surface and the surrounding area as well as 10: 1 between the screen and another environment are optimal. Reflection levels of:

• 0.7 to 0.9 for the ceiling,
• 0.5 to 0.8 for the walls
• 0.2 to 0.4 for the soil,
• 0.15 to 0.75 for work surfaces - as matt to silk matt as possible

Glare and reflection
Good office lighting avoids direct glare (e.g. by non -shielded light sources) and reflex fade (e.g. by shiny surfaces). Adjustable blinds, partitions or matt screens can help to minimize these problems. In order to reduce disturbing light sources in the field of vision, the so-called UGR value (unified glare rating) should be less than 19. Reflections often arise from windows or lamps that are reflected on screens or smooth surfaces. This can not only worsen aperture, but also the contrast of the screen display. Therefore, you should avoid shiny displays, transparent prospectus cases or high-gloss surfaces in the workplace. The placement of the lights also plays a role: open lights in which the light source is visible should also not hang directly above the workplace. And the daylight also has its pitfalls: desks should be aligned in parallel to the window front in order to avoid glare due to light from behind or from the front. Adjustable blinds or sun protection systems help to regulate too strong brightness - and ensure that dazzling sunlight stays outside, while pleasant daylight can work inside.

Light direction and toilet
Shadows also have their right to exist in the office - as long as there are not too many or too few. Because without a certain amount of shade, the eye lacks spatial orientation, but too strong or hard shadows disturb the concentration. The solution: A broad light distribution that offers direct/indirect lights. For jobs with special requirements - for example through technical devices or special activities - you should select lights with a suitable light intensity distribution.

Light color and color rendering
The light color, expressed in Kelvin, influences the atmosphere and can promote well -being and productivity. Warm -white light (up to 3,300 K) creates a cozy atmosphere, while cold white light (over 5,300 K) can support the concentration. The color rendering (CRI) is also important because it determines how natural and lively colors appear under the artificial light. A high CRI value (over 80) is essential for an accurate color perception.

Flicker
Even if we do not always consciously perceive it - flickering light can heavily use and leads to headaches, concentration problems and faster fatigue in the long run. Such flicker symptoms arise especially with outdated lighting technology. Modern lights remedy with electronic ballasts that ensure even lighting.
