REVOLUTIONARY TECHNOLOGY

BIO-OPTIMISED PRO-COGNITIVE INTERIOR LIGHTING

A short video about us

We supply biologically optimised pro-cognitive patent-protected lighting systems

Spectrasol is a supplier of biologically optimised pro-cognitive patent-protected lighting systems, whose authors and advocates are leading Czech experts, scientists and recognised authorities in lighting and lighting technologies. In fact, light fundamentally affects our feelings, performance and health. If today, people are intensely engaged in what the society breathes, drinks and eats, concentration on the influence and potential of light comes into play as another key opportunity that can influence and control our body, mind and mood.

Interior environments will feel like the outdoors

Spectrasol pro-cognitive and regenerative full-spectrum LED light source imitates natural sunlight

People are spending more and more time indoors under insufficient artificial lighting. This shift in light exposure is rather unfortunate because the human body is evolutionarily adapted to full-spectrum sunlight which has an essential impact on health, performance and the general mental state.

Our revolutionary pro-cognitive lighting technology, which is based on human biorhythms, ensures that the properties of artificial lighting match the properties of natural light from the Sun.

During the day, our pro-cognitive LED sources emit a high proportion of cyan and neighbouring blue and green wavelengths. These wavelengths are faithfully represented just like in the Sun’s daylight. They entrain the human circadian rhythm and stimulate the body to full alertness and activity as well as support cognitive performance and overall vitality of the human body. At the same time, they promote the secretion of the hormone serotonin during the day, which in turn promotes melatonin secretion at night and supports the resulting regenerative and immune processes of the body during sleep.

Spectrasol ligthing thus improves the life, health and performance of people, creates a more stimulating, performance-efficient and attractive environment to organisations as well as better work or study results and prosperity.

WHY Spectrasol

Daylight at noon constitutes of bright white light with a continuous spectrum spanning across the UV region, the entire visible spectrum as well as the photobiomodulation region (deep red and near infrared spectrum). The emission continues deeper into invisible infrared and radio wavelengths.

The unique benefits of Spectrasol lighting

  • Pleasant and uniquely comfortable white light approaching the biological effectiveness of the sun (its circadian efficiency was evaluated in an experiment at Prague secondary schools according to the CIE at 97% efficiency of the sun) (CIE, POSITION STATEMENT ON NON-VISUAL EFFECTS OF LIGHT, 2019)
  • Naturally stimulates the body and works to improve overall physical and mental health, vitality and immunity.
  • Does not damage the eye through the so-called Blue Light Hazard (aktivní link na Blue light Hazard subpage) (also known as Harmful blue light effect, hereafter referred to as BLH)
  • Regenerates the retina of the eye in real time and repairs damage caused by light source emission in the BLH area (aktivní link na Reparation Efficiency subpage)
  • Increases yield/man-hour (aktivní link na Pro-cognitive effectiveness subpage) – supports cognitive performance, alertness, concentration and emotional attunement (as evidenced by our own research studies, i.e. 10-20% improvement in cognitive tests results at Prague grammar schools as well as a 100%+ increase in the rhythmic amplitude of melatonin secretion levels among the residents of the Home for the Elderly in Beroun, Czech Republic).
  • The product represents the top trends seen in lifestyle and lighting industries:
    • the trend of a healthy lifestyle and care for physical and mental health
    • the growing trend of protection against BLH
    • the business trend in lighting towards biologically optimised lighting

How does Spectrasol work?

Technical features of the product and its innovative elements

  • The Spectrasol light source provides high-quality white light with a uniquely balanced spectral composition in the visible range of the sunlight spectrum (90% radiation match in the range 440-670 nm).
  • The intensity of the emitted light in the procognitive region (460-500 nm with a maximum at 480 nm) is equalized. Existing white light sources have a standard prominent drop in this area and/or suffer from high radiation intensity in the BLH region (415-455 nm) (CIE opinion on Blue light hazard of 2019).
  • Does not emit concentrated energy in the blue-violet risk wavelength range of BLH
  • The intensity of the emitted light is also enhanced in the photobiomodulation region (670 nm) supporting retinal regeneration
  • Available in surface-mounted, embedded and suspended versions
  • The luminaire consists of a simple system of standard LED chips mounted on common PCBs without a control system
  • It is compatible with common lighting control systems, e.g., DALI
  • The effectiveness of the product is verified by experimental research of the Czech Technical University, the Czech National Institute of Mental Health as well as other independent scientific institutions

Implementation

The potential for a wide range of applications

The need for a full-spectrum light exposure when indoors during the day is unquestionable as evidence by a peer-reviewed research that stood the test of time and meta-anlyses across varied fields such as general medicine, chronobiology, cancer, diabetes and sleep research among others. As such, the application of the Spectrasol luminaire is extremely broad and versatile. The luminaire profoundly improves the indoor environments across industries, organisations and other facilities such as:

  • administrative and production facilities,
  • teaching and training facilities,
  • service and dispatch centres,
  • laboratories and development workplaces,
  • hospitals and operating rooms (ORs)
  • shops and service establishments,
  • social facilities,
  • offices and public administration buildings,
  • home and other interiors.
