Natural light changes colour throughout the day – from a morning sunrise glow, to a bright midday sun, to a rich warm sunset. We have the technology to change the colour of artificial light in our homes – Human centric lighting*.
The human biological clock is closely tied to the day/night cycle of the Earth – circadian rhythm, and is pivotable for our body’s release of various hormones including melatonin that regulates sleep, and cortisol for healing. We know that light has a significant influence on the human biological clock and our health.
As much as technology can benefit us, it can disrupt our natural biological clock. We have too little of the right type of light during the day, and too much of the wrong type of light at night. Exposure to televisions, LED lights, computer screens, and mobile devices that emit blue (cool) light at night can disrupt our biological clock, delaying the natural sleep pattern.
Currently, lights are specified to be a particular colour temperature – typically warm white, or cool white. As a general rule, warm light is more suitable for a home because it is best for the worst case scenario. Up until now we have had limited control of light – we switch on/off, and dim.
LED lights are now available that can reproduce a range of colour temperatures (tuneable white light), and even the whole colour spectrum. Together with a compatible lighting control system we can automatically regulate light to achieve specific objectives.
With a human centric lighting system, artificial light can automatically mimic natural light. As natural light changes throughout the day and night, so too can the colour and intensity of artificial light – re-aligning our circadian rhythm to our biological clock.
A human centric lighting system can also manipulate artificial light. When we require higher levels of concentration and alertness, we can adjust the colour temperature to provide a cool light. When we want to relax or provide a more calm environment, we can adjust the colour temperature to provide a more warm light.
A better light
Lighting and control technologies have evolved to provide better user experiences. With careful consideration and expert consultation, light can be more organic and integrate better in our smart homes to provide greater levels of comfort.
For the ultimate lighting experience, let me show you how.
*Human centric lighting is also known by other names such as circadian lighting, bio-rhythmic lighting, tuneable lighting etc.
