Towards Human Centric LEDlighting

13 12 2015
The impact of light on our well-being has made us more aware of the different lighting solutions. By changing the intensity and colour temperature of light we can impact on mental alertness and comfort.

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.

Lighting the Learning Environments

The use of Human Centric Lighting is not only suitable for the medical-therapeutic sector, but also for school and office. It is, however, the only competent lighting design that enables the optimal utilization of new intelligent lighting solutions.

The newest way to school lighting is to move the teaching and the kids outdoors. Excellent experiences, especially from England and Sweden, have been made. If the outdoor learning is not possible one day because of the bad weather, education traditionally takes place inside the classroom.  However, ensure that the lighting inside is similar to the outside one, that is daylight simulating light, 5,500 K with high colour rendering index, over 90.

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 has been known that the full spectrum of sunlight increases the reading speed  by up to 20%, and reduces eye fatigue. So daylight is the best option for schools.

According to the most recent studies, the daily outdoor activities may reduce the need for children’s short-sightedness eyewear. This article was provided by the Journal of the American Medical Association (JAMA).

Transforming Outdoor Learning in Schools

Good lighting design always meets the customer’s individual needs. My role is to provide the best solutions. With over 30 years of experience, I served thousands of satisfied customers.

Most of my clients choose a natural daylight for the interior lighting. If you have a lighting project for your work place or home, I would like to help you to get a modern, Human-Centric LED lighting.

However, you can also choose a solution, where you can choose the light colour from e.g. 2,700 to 5,500 K.

Before you read more, here is my new article from the housing fair in Finland, with many pictures about the human centric home LED lighting.

Spectrum is the most important thing to decide on the light quality. I prefer a 5,500 K continuous daylight spectrum, however, in the evening you could choose warmer light in order to sleep better.
