Full Spectrum LEDs and Indoor Daylight Support for Health and Wellbeing
Daylight is the preferred light source of choice for human centric lighting applications in the built environment, as the human visual system and physiology has evolved under this environmental condition. Conventional white LED light sources pump on blue (≈450nm) and show an unbalanced spectrum with a prominent peak in the shortwave region of the visible spectrum. This disturbed emission might be associated with several discomfort and health issues. Innovative technologies in optoelectronics based on purple dies and multiple phosphors offer an emission very similar to daylight, particularly indoor after the glazing media.
We propose to consider the light provided by full spectrum LEDs as indoor daylight in building standards and regulations.
