BIOS SkyBlue™

We have evolved with blue sky and daylight as natural cues to keep our body clocks aligned with the 24-hour day. Healthy contrast between daylight and darkness allows our circadian rhythms to function as designed. While this natural lighting cycle is healthy, hospital lighting typically feels anything but natural. BIOS SkyBlue technology bridges the gap, stimulating the circadian response while maintaining the appearance of white light in familiar color temperatures.

NEW!! A second generation of BIOS technology– with improved color consistency, higher efficiency, and more control options –has expanded the Axis Lighting offerings 

Axis partnered with BIOS to seamlessly integrate SkyBlue technology in Axis luminaires, with the aim to create environments that improve alertness and promote better sleep, health and well-being. This is especially important in healthcare settings, where daily schedules and life events vary greatly among its diverse populations, and require tools to create circadian-supportive environments for both day-active and 24-hour applications.

Axis now offers……more design flexibility.

Axis now offers a Dynamic solution that works specifically with select BalancedCare products, which we call DynamicCare™ for BalancedCare. We also offer a BIOS tunable white option (BTW), which allows independent control of spectrum and intensity.  More options – more design flexibility.

What You Don’t See Can Help You The Benefits of Natural Light without Compromised Light Quality

To the naked eye, the white light produced by a BalancedCare™ luminaire with SkyBlue option may appear identical to the white light from traditional LEDs, but the actual spectrum is different. Luminaires with SkyBlue deliver greater melanopic content. This effect is reflected in higher melanopic ratios that contribute to higher Equivalent Melanopic Lux (EML), Melanopic Equivalent Daylight Illuminance (MEDI), and Circadian Stimulus (CS) calculations, three current circadian lighting metrics. When compared to traditional LEDs, SkyBlue technology can also achieve equivalent circadian impact at lower illuminance levels, resulting in better visual comfort.

The Science Behind the Solution How Does it Work?

BIOS SkyBlue lighting solutions deliver the health-enhancing blue-sky wavelength of the light spectrum. Recently discovered photo receptors in the human eye – photosensitive retinal ganglion cells or ipRGCs – contain the protein, melanopsin, which is highly sensitive to that blue-sky wavelength. When melanopsin is stimulated by light, the ipRGCs send a signal to the body’s master clock, telling it to reset its cycle for the next 24 hours. That signal triggers a variety of biological processes, including essential hormone production (e.g. early morning cortisol for alertness and nighttime melatonin to promote sleep). As a result, SkyBlue, with its 490 nm peak in the light spectrum, can help provide an effective stimulus during the day to promote healthy circadian rhythms. SkyBlue also peaks in the far-red wavelengths (near 660 nm) to help healthcare professionals better discern veins and visually diagnose and treat diseases through skin, such as cyanosis.

    Maintains appearance of white light at each CCT while imperceptibly delivering a spectrum with greater melanopic content.
  • Static system supports proper daytime circadian stimulus

    The static spectrum delivers a steady but imperceptible blue-light boost to white light throughout the day, in choice of 3000K, 3500K, or 4000K.
  • Dynamic system for 24-hour facilities - like hospitals
    Dynamic system for 24-hour facilities – like hospitals
    The dynamic spectrum contains full SkyBlue content and uses integral Bio-Dimming™ module to gradually remove the “blue,” while keeping light output constant; use where full light output is desired as the day progresses while minimizing circadian impact in the evening.
