Personal Good Light: the second LED revolution

Updated: Sep 17

Around the year 2010 LEDs became the lighting industry’s main light source. The trigger for this transition was energy saving. Their introduction was one of many enormous contributions from the lighting industry to fight global warming. Lighting systems became an integral part of smart buildings and sometimes even the backbone. This enabled several additional features like connectivity, LiFi, presence detection, indoor positioning, asset tracking and management, information about the use of buildings or streets, etc. This is the first LED revolution and it’s in full swing.

The second LED revolution is the introduction of ‘good light’. This will be even more impactful because it affects the billions of people that have to live and work inside. We spend more than 90% of our lives indoors where we are to a large extent deprived of natural daylight. Science is very clear about this: we need daylight to synchronise our biological clock. Lack of exposure to daylight causes poor quality sleep which can make us unfit and subject to mood swings.

The second LED revolution is focussed on health and wellbeing. People need daylight. The lack of natural daylight in buildings can be compensated with Personal Good Light. This will make the lives of billions of people healthier. It will bring them better sleep, more energy during the day and an improved mood. Upgrading the current ambient lighting systems and adding Personal Good Light is an obvious way to go to improve the life quality of billions! Join the movement of Good Light.
