People-centered lighting design

Today, people spend most of the day in our jobs, exposed to artificial lighting and with hardly any access to natural light. That is why we know, from Luxes, the importance and responsibility we have when it comes to offering lighting solutions. Light affects humans directly, as it is the main environmental stimulus involved in the synchronization of the circadian rhythm.

But let’s start from the beginning
What is the circadian rhythm?

Circadian rhythms are physical, mental, and behavioral changes that follow a 24-hour cycle. The word circadian means “about a day” and comes from Latin: “circa” (around) and “diem” (day). The main factors that affect this cycle are light and dark. Most of the vital functions of the human being obey this rhythm.

On the other hand, we have biological clocks, which are molecular mechanisms that serve to adapt certain behaviors to different phases of the day or year. They are responsible for regulating the cycle of circadian rhythms. This clock is located in the brain, specifically in a region called the hypothalamus. Signals from the hypothalamus are transmitted to different areas of the brain, which respond to light, including the pineal gland. In response to light, the pineal gland stops producing melatonin, a hormone that causes drowsiness. After dark, the level of melatonin in the body tends to increase, making it feel sleepy.
The circadian rhythm in humans implies that, during the 24 hours of the day, there is a time destined for rest and another for activity. This rhythm begins when the sun rises, during the early hours of the day. As the position of the sun begins to rise and the temperature of the light becomes colder, we are more active, alert and productive. To better understand this concept, let’s look at the example shown below of this cycle in a human being.

Human Centric Lighting
People-centered lighting design

Human Centric Lighting is a lighting solution designed with the aim of creating an environment, usually of work, that simulates the changes of natural light, with its visual, biological and emotional effects. The focus of this lighting concept is on health, well-being and the proper performance of human activities. This effect of natural light is achieved by adapting the color temperature and lighting levels. These changes in color temperature are made by a smart light source, usually a device with LED technology. For example, in the morning a neutral or cold white light should be used to improve people’s effectiveness and alertness. On the other hand, during the night no blue light should be used to improve sleep. If we talk in Kelvin, a very sunny day with totally clear skies would correspond to about 6000K while a very cloudy day could reach 12000K.

The Human Centric Lighting, is designed mainly for offices since it is the place where we spend most of the day, but its scope of application ranges from offices to industry, education, hospitals or retail.

One of the sectors with the most boom of these luminaires are hospitals, due to the health benefits. LCH can be effective in reducing therapy times and improving the effectiveness of medications. Studies carried out on the impact of light in hospitals and doctors support the growth of this market. The benefits of this people-centered lighting are many more. HCL optimizes sleep-wake cycles, improves alertness, increases performance and improves mood, among others.

In LUXES we design, manufacture and offer solutions in lighting systems with HCL technology, we have a wide range of recessed, surface and suspended luminaires with intelligent control systems. Our recessed luminaires with HCL technology are fully integrated into the architecture of the space where they are located, providing the benefits of different color temperatures throughout the day. We also have linear and curved systems, versatile and efficient, which combine their characteristics, with clean and minimalist designs integrating HCL technology and thus achieving excellent light quality.

Declare is a product labeling program based on the Red List Label for material evaluation.

The LBC Red List of the Living Building Challenge (LBC) represents materials, chemicals and elements that pose risks to human health and the ecosystem and that their production should be phased out.

At Luxes we are pleased to announce that our luminaires are Declar certified and comply with the Living Building Challenge.

As a result of the hard work of our engineers, Luxes lighting systems offer state-of-the-art LED performance, while combining varied design options, to meet specific lighting needs in different applications.
