Non-visual effects of light depends critically on the intensity, the duration and the spectral composition of the light. Also the prior light exposure and the timing of the exposure determine the kind and size of the non-visual effects that can be achieved.
Human centric lighting is becoming more common. The new technology updates enable cost effective and user friendly solutions. Human Centric Lighting is the inclusion of visual and non-visual (biological) needs of humans in the design of lighting applications.
The lighting is changing quickly. For the new lighting projects is LED lighting today the best option. LED prices have dropped and the quality is improved.
Lighting can be used to increase the labor productivity, the welfare of the people, comfort and safety. You can also use new technologies to improve energy efficiency.
Light with a high spectral blue component activates and increases the capability for performance and concentration. If this blue component in light decreases, the body relaxes and changes over to a calm phase. Light control offers further positive effects on the human biological rhythm. It is able to improve motivation, the ability to concentrate and therefore productivity as well, and it provides ideal support with intellectual tasks.
George Brainard, the director of the Light Research Program at Thomas Jefferson University, hopes his research on how the colour of light is interpreted by our eyes will be able to get patients out of the hospital sooner.” Maybe the order should be changed, so that millions of suffering people could benefit earlier from his findings as soon as possible.
The use of Human Centric Lighting is not only suitable for the medical-therapeutic sector, but also for office, school and industrial areas. It is however only competent lighting design that enables the optimal utilisation of the new intelligent lighting solutions.
If you have a lighting project for work place or home, I like to help you to get a modern, Human-Centric LED lighting.
Good lighting design meets always the customer’s individual needs. My role is to provide the best solutions. With over 30 years of experience, there are thousands of satisfied customers.
Most of my clients have decided to choose a natural daylight for interior lighting.
Hoever, you can also choose a solution, where you can choose the light colour from e.g. 2700 to 5500 K.
Spectrum is the most important thing to decide the light quality. I prefer 5500 K continuous daylight spectrum, however in the evening you could choose warmer light in order to sleep better.
Good daylight spectrum
Bad, non-continuous spectrum
Some benefits for human-centric lighting
To promote the safety for the working environment lighting and ergonomics.
The school’s main goal is to get the pupils to learn. So the Human Centric Lighting is very important in schools.
However, most of the schools are illuminated by a traditional, warm, tired light (mostly 3000-4000 K).
It is known that the full spectrum of sunlight increases the read speed of up to 20%, and reduces eye fatigue. So daylight is the best option for schools.
According the newest studies the daily outdoor activities may reduce the need for children’s short-sightedness and eyewear. This article was the Journal of the American Medical Association (JAMA).
