human centric lighting

Did you know that the type of light you are exposed to can have a profound impact on your health and well-being? This is especially important when it comes to lighting your home or office. In recent years, human centric lighting has become a popular topic among professionals and homeowners alike.  

But what is human centric lighting, and why should you care? In this blog post, we will discuss the benefits of human centric lighting and how you can incorporate it into your next build or retrofit! 

What is Human Centric Lighting?  

Human centric lighting, also known as circadian lighting, is a type of artificial lighting that is designed to mimic the natural light cycle of the sun. This means that the light intensity and color temperature will change throughout the day, to match our natural circadian rhythm. HCL aims is to improve user comfort, mood, and productivity. HCL is delivered via tunable light-emitting diode (LED) fixtures that are simple to adjust to imitate sunlight. 

Instead of providing constant, non-adaptive lighting regardless of activity or time of day, human centric lighting replicates the dynamic changes in light intensity and color temperature that occur throughout the day. HCL provides light that is biologically optimized to help you concentrate and be productive during the day, while also encouraging relaxation and regeneration at night. 

A holistic approach to biologically effective lighting systems considers the effects of light on both biological and emotional aspects of human physiology while also providing visually pleasant and helpful illumination.

Light and Our Circadian Rhythm 

Our circadian rhythm is our natural 24-hour sleep/wake cycle. This internal clock is affected by environmental cues, such as sunlight and temperature. When our circadian rhythm is disrupted, it can lead to a number of health problems, including fatigue, insomnia, and depression

In turn, the color of light affects the circadian rhythm, which is why human centric lighting is so important. By mimicking the natural light cycle, both daylight and evening light, we can help to regulate our internal clock and improve our overall health and well-being. 

How Light Affects Our Moods and Emotions 

It’s no secret that light can affect our moods and emotions. For example, think about how you feel when you walk outside on a bright, sunny day compared to a cloudy day. The bright sunlight can make you feel happy and energetic, while the dreary clouds can make you feel sad and gloomy. 

This is because different types of light have different effects on our brains. The bright, white light of the sun is known to boost serotonin levels and improve moods. On the other hand, the orange and red light of a sunset is known to promote relaxation and calmness. In fact, red light is one of the best colors for inducing sleep as it doesn’t disrupt your circadian rhythm.  

So, what does all this mean for human centric lighting? Simply put, human centric lighting can be used to improve the overall quality of your life. By mimicking the natural light cycle of the sun, HCL can help to regulate your circadian rhythm and promote better sleep, moods, and productivity. In addition, human centric lighting is a great way to improve the comfort and aesthetics of your home or office.

The Benefits of Human Centric Lighting 

There are a number of benefits to be gained from using human centric lighting in your home or office. Some of the most notable benefits include: 

  • Improved sleep and moods. Human centric lighting may improve sleep quality, reduce fatigue, and induce melatonin production. In addition, HCL can also help to improve moods and reduce the risk of depression. 
  • Regulated circadian rhythm. As we discussed earlier, our circadian rhythm is regulated by environmental cues, such as light. By using human centric lighting, we can help to improve our internal clock and reduce the risk of health problems caused by a disrupted circadian rhythm. 
  • Increased productivity. The right lighting can help to improve productivity levels. For example, blue light boosts alertness and focus, allowing you to work more efficiently. 
  • Enhanced comfort and aesthetics. Human centric lighting can also help to improve the comfort and aesthetics of your home or office. The right light fixtures can add a touch of luxury and sophistication to any space. 
  • Visual comfort. Human centric lighting can also help to improve visual comfort. For example, HCL can be used to reduce glare and create a more comfortable work environment. 
  • Reduced energy costs. One of the best benefits of human centric lighting is that it can help to reduce energy costs. By using the right light fixtures, you can save money on your electricity bill without sacrificing comfort or aesthetics. 

As you can see, there are a number of benefits to using human centric lighting in your space. 

Implementing Human Centric Lighting in Your Home or Office 

If you’re interested in implementing human centric lighting in your home or office, there are a few things you need to know. First and foremost, you’ll need to invest in some tunable LED lighting fixtures. These light fixtures can easily adjust to imitate the natural light cycle of the sun. 

The process of installing your lighting should begin with a consultation with a low voltage specialist. This will ensure that your fixtures are installed correctly and that you’re using the right products for your needs.  

Then, talk to your home architect about how the lighting design and layout of your home can improve with human centric lighting. It’s important to plan for your installations before you construct your new home or retrofit your existing one. If you are building from the ground up, you may want to include some special features, such as a lightwell or skylight, that can help to improve the natural light environment of your home. 

If you are retrofitting your home, you may want to consider installing a dimmable LED light fixture in every room. This will allow you to adjust the amount of light depending on your needs and preferences.  

What are Tunable LED Light Fixtures? 

Tunable LED light fixtures specifically imitate the natural light cycle of the sun. These light fixtures can easily adjust to match the color temperature of the sun at different times of day. This allows you to create a space that is comfortable and inviting no matter what time it is. 

In addition to tunable LED light fixtures, you’ll also need to purchase some light bulbs.  

Lighting Control System 

In addition, you’ll need to purchase a light control system. This system will allow you to easily adjust the color and intensity of your light fixtures. By doing so, you can create the perfect lighting environment for any time of day. 

One of the most popular light control systems on the market is the Lutron Caseta. This system allows you to control your lights from your phone or tablet. You can also create schedules, so your lights will turn on and off automatically. 

Installing a light control system is a great way to save money on your energy bill by using less electricity. And if you integrate your light fixtures with other smart home devices, you’ll have even more control over your home.  

Light Fixtures & Smart Home Automation 

Finally, you’ll need to install your light fixtures and smart home automation system. If you’re looking to go all out, you can also integrate your light fixtures with other smart home devices. This will allow you to control your lights from one central location.  

By installing a few simple devices, you can control your lighting levels and energy consumption from your phone. You can also create schedules and routines to make your life easier. 

Once you have your lighting fixtures installed, it’s important to use them correctly. Make sure that all occupants of the space are aware of how to adjust the lights and what times of day to use them.
