Correct lighting positively influences Health and the Environment. Ergonomic lighting adjusts daily rhythms, improves well-being and boosts job performance. Efficient lighting reduces energy consumption and limits costs and environmental impact.
Vision is our most important sense and represents more than 80% of sensory perception. As we age, the eye changes and our eyesight diminishes.
Light resets our biological clock and regulates our daily rhythms including alertness, hormone production and activity.
- The lens becomes yellow, harder and more difficult to focus.
- The eye is less able to adapt from areas of light to areas of dark.
- There is clouding of the inner eye which reduces light transmission and increases glare sensitivity.
Individual control over workspace lighting increases well-being and productivity.
- Blue wavelengths, which are present in cool white light, have the greatest affect on our daily rhythms.
- Human Centric Lighting (HCL) solutions, which copy the daylight effect, affect our concentration, motivation, well-being and productivity.
- Direct glare from a lightsource or window, or indirect glare from a reflective surface, may cause health-related problems. Asymmetric task lights cast light at an angle to reduce light reflections, and thereby glare, from the worksurface.
- Incorrect seating positions adapted in order to see better may cause neck, back or shoulder pains, and sore eyes.
- Frequent changes in the peripheral field of vision generate stress.
Correct lighting simplifies orientation and increases perceived safety.
- Different work requires different lighting environments.
- Dimming allows variation in the light which the eye appreciates during the workday.
- An ergonomic task light ensures optimal workspace lighting by providing individual adjustability.
Energy-efficient luminaires save cost and help the environment.
- Light shows the way and eases orientation.
- Light improves contrast reduction by making it easier to differentiate between an object and its background.
- An environment with direct/indirect lighting is preferred by most employees as the direct illumination creates shadows and the indirect illumination creates good contrast through a diffuse light.
Clever lighting solutions are necessary to comply with the environmental requirements of the future.
- The efficacy of the lightsource is determined by how much light is produced for each watt used. This is known as lumens per watt or lm/W.
- LED lightsources found in energy-efficient task lighting are more efficient than the fluorescent tubes most common in general lighting.
- The combination of luminaire design, lightsource, and optics determines the efficiency and light quality of a task light.
- National regulations, such as LEED, dictate requirements for energy classes (e.g. energy expenditures in office environments).
- Energy-efficient luminaires, sensor technology and controls systems may reduce energy use in buildings by up to 90%.
