What is Human-Centric Lighting?
It is known that lighting increases our body temperature by
tiring our eyes after a certain period of time. As a result of research, we
spend most of our lives indoors with artificial light. Human-oriented lighting
is an understanding of lighting that deals with all aspects of people's
comfort, creativity and physical competence indoors.
Human-Centric Lighting (HCL) can be defined as artificial
space lighting in accordance with the effects of light on humans. In lighting,
it should also be synchronized with artificial lighting where necessary, adding
sunlight to our daily lives.
We need light to see, and light affects a large part of our daily routine. From the moment we wake up until the end of the day, we plan our lives according to the state of the light. In situations where we have to work, travel or be awake at night, our biological system cannot adapt directly to this change and we are physically affected. This can lead to consequences such as sleep disturbance or stress in our body.
Why do we need human-centred lighting?
People are affected both physically and biologically by
artificial light. When constructing a light system, we need to take into
account our physical activities and biological abilities. Studies should be
carried out to ensure ideal light comfort in inadequate environments.
All living things have an internal clock called a
“circadian”, and a circadian means that, with exceptions, we wake up at sunrise
and go to sleep at sunset. Adjusting the order of sleep and wakefulness
according to the sun affects our whole life. It is very important to use HCL
solutions when designing schools, health units, workplaces and industrial
buildings where we spend our daily lives.
Natural and artificial light is one of the most important factors affecting our mood and activity level. Artificial lights applied by imitating natural light are one of the methods applied indoors to comply with sunlight. Human-optimized lights also vary according to the intensity of the sun.
When planning human-oriented lighting, there are some measures such as light spectrum, the intensity of light, timing and duration of light, distribution of light; these measures should be considered in their own way when designing each structure.
The Spectrum of Light
It has been scientifically proven that the blue wavelengths of light add activity to our business life. In our homes and workplaces, we use blue spectrum light sources in cases such as sending warnings to our bodies and staying awake. When we need to rest or relax, we benefit from the effect of yellow light.
Light Intensity
According to research, the intensity of light needed by our
body varies according to our working and resting state. In order to distinguish
such situations from each other and to provide the necessary energy savings,
human-oriented lighting solutions should be made.
Timing and Duration of the Light
With the rise of the sun, our need for artificial light decreases, and our biological clock begins. The need for artificial light begins at sunset and ends at the time of sleep. The use of natural light and the use of sunlight should be planned correctly and applied most efficiently according to our body to ensure a 24-hour cycle.
DOES DAYLIGHT DETERMINE OUR QUALITY OF LIFE?
With the increase of urbanization and the change of building
types, the place of artificial light in our lives has increased considerably.
We are now providing productivity everywhere with hybrid work and home-office
work types that have developed after the pandemic. For a productive life
without affecting our health, we need the natural effects of daylight.
Human-Oriented Lighting has a positive effect on performance. By working in offices that make insufficient use of sunlight, we are gradually moving away from the natural elimination of our body's needs. The lack of daylight in our biological rhythm can lead to biologically serious physical problems.
Aspen Lumuner LED Lighting products are designed to be integrated
into all-metal, rock wool and wooden suspended ceiling systems, especially
suspended ceiling systems. With the integration of LED lighting into suspended
ceiling plates, suspended ceilings and lighting solutions create integrity.
Thus, it provides innovative and aesthetic solutions in architectural projects.
Lumuner, The Standard Solution LED Lighting systems are adjusted according to the power and lumen values determined according to the need, the system structure can be produced in the desired colours and customized according to the suspended ceilings.
In special spaces that require volume acoustics, completely modular products are offered with perforation and grouted options. Conference rooms, call centres, hospital projects, meeting rooms, gyms, residential projects, offices and school projects are widely preferred systems.
