Equipped with patented full-spectrum LED technology with unique circadian effect

We produce and distribute pavilions in cooperation with the renowned Czech company Silentlab.
  • Can be used in outpatient or hospitalisation applications
  • Proven effectiveness for a range of mental disorders
  • Detailed NIMH certified methodology can be used in application
  • Circadian effect comparable to the sun
  • High representation of azure wavelengths in the 460-520 nm region providing maximum melanopic stimulation
  • Simple system for controlling time and intensity with direct wifi connection
  • Flat multi-sided distribution of therapeutic light
  • High light intensity while maintaining visual comfort

The pavilion is a large phototherapy device for promoting psychological well-being and stabilizing circadian rhythms. It is a self-contained cubic structure with a side of 2.5 meters that can be placed in a lobby area, waiting room in a mental health centre or similar institution providing inpatient and outpatient care. Inside it there is comfortable seating for up to 6 people.

The entire structure has a pleasant modern design with a combination of soft upholstered surfaces in light colours and natural wooden surfaces. The entire ceiling and half of one side wall are fitted with LED light sources with diffusers so that the whole area is lit and creates a feeling of open space, of sky, with its low, balanced brightness. The two side walls of the pavilion are open, fitted with curtains that allow creation of a private space and at the same time promote the even distribution of light.

The effectiveness of the pavilion is ensured by the combination of high illuminance, efficient spectrum and multi-directional, even light distribution in the space. To ensure good patient acceptance of the therapy, the visual comfort of phototherapy is based on the size of the illuminated area, its position in the field of view and the brightness conditions it produces.

  • A high therapeutic impact is made possible by the use of Spectrasol Therapeutic’s unique light spectrum technology (protected by patent no. 308363) with a high representation of wavelengths in the sensitivity range of ipRGC cells, which act on the circadian system. At the same time, the composition of the spectrum is beneficial for the eyes of the user due to the limitation of harmful blue wavelengths below 450 nm and the content of red wavelengths around 670 nm.

Unique spectral composition and key areas of emitted therapeutic light Spectrasol

  • Compared to commonly available phototherapy devices, the pavilion offers a spatial solution with a large-area light source that covers more than 40% of the field of view. The dominant light flux is directed from above. The large emitting area makes it possible to achieve a pleasant diffuse character of light in the space without the presence of glare from high brightness on the surface.
  • The power of the light source can be infinitely adjusted according to the therapy needs. The basic setting offers two levels. At higher power, the so-called therapeutic mode, the illuminated area reaches the average surface brightness of a summer sky. In the lower power, so-called civil mode, the brightness of the area corresponds to an overcast sky. Achieved illuminance converted to the melanopic sensitivity of ipRGC cells (melanopic EDI) corresponds to the values required in Czech and international standards for phototherapy.

Verified efficacy

The National Institute of Mental Health of the Czech Republic conducted a validation of the efficacy of phototherapy in the Spectrasol phototherapy pavilion on healthy subjects and the clinical population. The aim was to verify whether the technology affects subjective experience, cognitive function and physiological variables, both immediately after a single exposure and after regular repeated exposure. Validation was conducted in the following six areas:

  • Visual comfort
  • Affective experience and mood
  • Cognitive function
  • Sleep
  • Circadian rhythms
  • Brain electrical activity
The detailed NIMH certified methodology, available as part of the delivery, can be used in the application see. QR link on the reverse side.

This phototherapeutic device is intended for treatment provided by specialized physicians and medical professionals only.

Certified application methodology – National Institute of Mental Health

Therapy can only be carried out on the recommendation and as instructed by a specialist doctor or therapist. Violation of these instructions may cause adverse effects on the body.
The development and application methodology of this device were created in cooperation with the CTU UCEEB and the NIMH in the project No. FW02020025 funded with state support from the Technology Agency of the Czech Republic and the Ministry of Industry and Trade of the Czech Republic within the TREND Programme.
