BIOLOGICAL LIGHTING featuring Bios®

Human Circadian Rhythm

LED FOR CIRCADIAN RHYTHM

THE 3RD RECEPTOR AND CIRCADIAN RHYTHM

PHOTOSENSITIVE RETINAL GANGLION CELLS
  • Does not contribute to sight (only rods and cones do)
  • Converts light into signals that stimulate biological processes
  • Melanopsin response during daytime drives circadian entrainment, signaling a whole host of biological processes to occur at the correct time. CCT DOES NOT
  • This leads to more energy during the day and more sleep at night.

Bios®: CIRCADIAN REGULATION SPEC

The ALPHABET Downlights Biological Series featuring BIOS® is redefining Circadian Rhythm LED by providing high melanopic lux (EML) in a desirable color temperature.

  • Patented SkyBlueTM technology provides spectrum important for circadian regulation and entrainment
  • Ideal spectrum for daytime light exposure without sacrificing preferred color temperature
  • Fills the “green gap” from traditional LED lighting
  • Color Rendering between 85 and 90 (CCT dependent)
  • Full CCT offering in 3000K, 3500K, 4000K, and 5000K
  • Spectral output designed to offer maximum protection from dangerous “Blue Light Hazard”
  • Each light engine is factory calibrated for consistent color point
  • Contributes towards satisfying WELL BUILDING STANDARD circadian lighting specs

WHAT DOES BIOS® SERIES FOR CIRCARDIAN REGULATION DO?

Circadian Rhythm is the human body clock that operates critical functions including the production of testosterone, growth hormone, cortisol, and melatonin. These hormones have a direct influence on a body’s overall functionality in key areas including:

  • Sleep
  • Cognition
  • Performance
  • Alertness
  • Metabolism

LIGHT IS THE STRONGEST TIME CUE FOR THE CIRCADIAN SYSTEM

Light signals the body clock whether it is night or day and therefore if it should be awake, alert, restful or regenerative. Photobiologists discovered a light-sensitive protein in the eye’s retina called Melanopsin that detects intensity or changing levels of light. This photoreceptor projects to a different, non-visual part of the brain where our circadian clock is located. So when sunlight gets brighter in the morning, melanopsin becomes very active and triggers the brain’s body clock, or suprachiasmatic nucleus, to shift into an active day pattern.

Bios®: CIRCADIAN REGULATION SPEC

The spike at 490nm and suppressed Blue Hazard Zone at 440-470nm allows for enhanced performance, energy and focus to the occupants. Bio process entrainment for a true Circadian Rhythm alignment with minimal “Blue Light Hazard”, saving your eyes from Macular Degeneration.

SPD of Bios versus Melanopsin and Blue Light Hazard Chart CIRCADIAN RHYTHM

BAD: Blue Light Hazard Zone 408nm to 480nm

GOOD: LEDRA BIOS Spike at 490nm for Sky Blue Melanopsin response

NO EFFECT: Color tuning or CCT changing

LEDRA BIOS DOWNLIGHTS

LEDRA limits BLH found in standard LED and daylight while spiking the beneficial 490nm sky blue

Reduces risk of eye damage while stimulating performance, alertness, focus during the day
