Human Centric Lighting represents a new concept of lighting that is focused on the human being, which aims to make artificial light resemble natural light as closely as possible in order to improve the quality of life and the well-being of the individual in their daily lives, taking into account the diverse environments that surround them.
Light is the most important regulator of the human body and influences many moments throughout the human life cycle, from sleep to work, improving aspects such as concentration and performance.
This is why, as living beings, people need both light and darkness. There is a daytime cycle in which we have to be active and another period during which we must rest. In this regard, LED technology enables the independent control over the three dimensions that are key to lighting focused on the human being: light intensity, colour temperature and direction.
As such, a high light intensity and a colder colour temperature help to keep us energised, improving our performance and alertness. This type of lighting is beneficial during the middle of the day. By contrast, a soft light with a warm colour temperature produces a calming effect and does not disturb our sleep, which is why it is recommended for the end of the day.
The field of application of Human Centric Lighting encompasses a wide spectrum: from offices, industry and education to retail and outdoor environments and architectural spaces, among others. Every space requiring lighting can be adjusted by using the Human Centric Lighting technique, resulting in the improved health of the individual and the view of their surroundings.
The potential benefits of HCL for the individual, regardless of their age, include optimised sleep-wake cycles, daily improvements in their alertness, performance and moods, as well as responses to seasonal changes.
These benefits can be achieved thanks to the new technologies and tools that permit a better adjustment of the colour temperature of the light and of the level of illumination and distribution so that the lighting mimics natural conditions as closely as possible.
Scientific studies on HCL focus on the development of its physiological and psychological benefits on the human being through the design of different types of lighting:
The light is not static but changes throughout the day in terms of its colour and intensity. An installation of this type promotes the necessary sleep-wake rhythm.
Light with a high blue component (or cold white) and which energises the body, increasing performance as well as the ability to concentrate.
Light with a warm white tonality (with a high red component) has a relaxing effect on our body.
Light that adapts to the chromatic intensity and tonality, depending on the emotional needs of the individual.
