Traditional LED and electrical lighting can negatively affect health

Light is an essential component of human life, and artificial lighting has evolved over thousands of years. Currently, six billion people worldwide have access to electric lighting, and 90% of the United States population spends under three hours with exposure to natural light every day. Previous research had shown that there are adverse health effects that come with using even what is considered our most efficient LED lighting technology. Electric lighting can cause disruption to the circadian rhythm, visual fatigue, tiredness, and depression. The materials used to produce conventional technology are also toxic and rare, causing a negative environmental impact.

Innovation mimics natural daylight and improves circadian rhythm

Researchers at the Georgia Institute of Technology have developed a light converter using thermally activated delayed fluorescence (TADF) molecules that mimics natural daylight so closely that the differences are visually imperceptible. The utilization of this invention reduces circadian rhythm disruptions and visual fatigue associated with poor lighting, thereby improving mood and psychological state.

Utilizing a blend of molecules that exhibit delayed fluorescence and a photopolymer resin, this technology creates light converters that produce white light that approximates daylight so closely that it has surpassed all currently available devices. These light converters are operated in a way that offers a solution perfectly suited for applications requiring circadian and human-centric lighting that is stable, high-yield, and energy-efficient. This technology is adaptive to various daylight conditions including weather, time of day, and latitude, and if implemented, those spending most of their time in artificial lighting could receive immense health benefits. This invention's utility is underscored by its theoretical ability to be utilized for all indoor lighting systems, resulting in an expansive range of potential applications.
