Dec 3, 2015: Today, LED lighting is been designed for various applications, and many of them are quite unique. An important LED lighting application that has been scientifically proved is for the wellbeing and mood illumination.
Of late, the trend for human-centric LED lighting is becoming popular, particularly in certain niche segments. Studies have proved that light is an effective time-cue that can efficiently set our body clocks. Researches have also proved that if human beings are exposed to wrong lighting, it can lead to a number of disorders in their systems. LED lighting designers and manufacturers are, therefore, creating LED lighting solutions that can not only give us perfect light but also enhance our mood and emotions.
LEDs are a good source of light that has the capability to be controlled to take care of our biological, emotional and visual needs. It can be easily done by changing the direction of light, luminance levels and color temperature. A LightingEurope?s study states that by 2020, LEDs will take over 90% of the human-centric lighting space. The study pointed out that human-centric lighting solutions take care of our circadian rhythm, and promote a person?s mood, emotions and health.
Potential market for LED human-centric lighting
According to industry reports, there is a huge potential global market for human-centric LED lighting and LED mood lighting, and by 2020, this share will be quite significant. As it has been scientifically proved that human-centric LED lighting has positive impact on people and children and can enhance the the ambience, it can be increasingly used in workplaces, schools, hospitals, commercial buildings, as well as at home. Therefore, it is expected that LED human-centric lighting industry will grow significantly, and will become a important segment in the coming years. In Europe, LED human-centric lighting is already showing signs of revolutionising the industry, but in the Southeast Asian countries like India, it may first pick up in the medical fields.
Western and central Europe have been predicted to be the largest markets?about 75%?for LED-based human-centric lighting by 2020. Northern Europe, southern Europe and eastern Europe will follow closely. However, In Asia, this trend is yet to gain momentum.
This market will also open up many business opportunities for many sectors like designing these complex LED lighting solutions, integrating them with software and installing them. The growth of this segment will also open up opportunities for the LED lighting manufacturers, as well as for many other sectors like engineering, architecture, software providers, solution providers, etc.
Importance of human-centric lighting
Alarming data about increase in mood disorders, anxieties and inefficiency in workplace forced researchers to wake up to the need to know the good and bad effects of lighting. Studies have established that improper lighting has negative impact on the users, like disturbance of mood and sleep cycles, increase in anxiety, even increase cancer pathologies in the long term.
How LED lighting can boost wellbeing
Human beings have a natural body clock which is controlled by natural sunlight. While, sunlight enhances the level of activity in the day, it is reduced by sunset, and finally, the body goes off into a sleeping mode.
Working on these lines, now, studies on human-centric LED lighting have opened up possibilities of linking LED controllability and psychological issues. Researchers have found that LED lighting can simulate this natural body clock, and can be controlled to imitate the effect of natural light on our body. LED lighting can be programmed to improve our wellbeing, control our sleep and waking cycles, boost concentration, etc.
LED lighting can be used to stimulate human organism biologically, leading to improving cognitive performance in office or classroom. LED lighting can also create emotionally stimulating atmosphere, which boosts positive emotions. Studies have also pointed out that LED lighting can prevent and heal chronic diseases. It can support the circadian rhythm of a person and boost her/his health and mood.
According to the LightingEurope research, human-centric LED lighting has a number of positive impacts on our body and mind. Right type of lighting helps us to sleep and rest properly, and perform with high energy when we are awake. It has enhances healing and help prevent many chronic diseases.
Light has a high spectral blue component that activates and increases the capability to improve motivation, concentrate, and perform well. If this blue component in light decreases, the body relaxes and become calm.
Lighting designers need to understand the different effects
In the past, lighting designers focused only on the visual aspects of light, as the main purpose of lighting was to enable people to see better. The visual aspects of light have a significant impact on our performance. For example, light must be bright enough to facilitate performance of out visual tasks, but if it is too bright, it can cause glare. Colour-rendering of the light is also important, especially for the doctors whole examining patients.
However, our visual needs are very different from our emotional and biological needs. While designing a lighting solution, the designer should take into consideration all these aspects of light. Lighting designers should be fully aware of these impacts and have proper guidelines work on these solutions.
Applications of human-centric lighting
Human-centric lighting enables many applications, for example, in the medical sector, in healthcare centres and commercial areas like offices, retail and education. Today, it is possible to support the natural biological rhythm at the workplace with color temperature daylight sequences, ranging from a stimulating effect in the morning to a more relaxed lunch period, and including phases of concentration in the afternoon and a soft transition to going home in the evening.
Future focus applications are, for example, manufacturing companies with multiple shifts, whereby optimized lighting systems are able to improve the sense of wellbeing and ability to concentrate.
Many institutes and firms are already developing LED lighting applications based on the concept of human-centric approaches. Fraunhofer Institute LEiDs GmbH has developed ceiling lights using RGB and white LEDs to imitate a sky with moving clouds, while a Japanese manufacturer has created pink lighting with different color temperatures to keep people more alert during the day, which, on the other hand, help to relax at night.
Human-centric lighting is an essential aspect for our wellbeing will definitely change the lighting world in the coming years.
