With our multi-channel LED engines any light spectrum can be recreated, including Sunlight. Light spectra have effects on human cognition, emotions, attention, productivity, hormones and affect our circadian rhythms. Our light engines can be programmed to positively affect our health and productivity in different situations.
The highest fidelity light
Our LED modules surpass the highest standards regarding spectral accuracy. This is accomplished by combining our multi-wavelength LED engines with an integrated spectral feedback, being able to guarantee spectral errors lower than 1% and color stabilities within 1-step McAdam ellipse (∆uv < 0.001) over their lifetime.
Real time calibration
Our spectrally tunable LED modules are provided with a control feedback through spectral and temperature sensors to account for wavelength shifts, flux fluctuations and include an overheating protection in case of a bad heatsink dimensioning or harsh conditions.
Human, animal, plant and object centric lighting
The project was funded by the FP7 program of the European Commission (www.hi-led.eu). With a budget near 5M€, Hi-LED has developed a family of IoT-connected smart LED modules with embedded spectral algorithms, which offer natural illumination patterns that can be used to foster our health and biology, among other things. A succinct summary of the main scientific results obtained with our LED modules can be found here.
The National Gallery (London, UK) is using our lights to study the color perception of paintings under different illuminations (i.e. spectral compositions) and the damage potential of different light patterns on pigments. In this video, our LED modules are used by the NG scientists to illuminate the “The Rape of Sabine Women” by Peter Paul Rubens under different light spectra. This was a life event posted on Facebook by the National Gallery to celebrate the British Science Week.
Human Centric Lighting
Sunlight changes in light intensity and spectral composition partly define the circadian cycle of living beings. The scientific evidence on the relation of light and the synchronization of our circadian system is unequivocal, as are the risks that a disrupted circadian system can pose to our health. Can you imagine a bright future were smart light engines dynamically adapt their spectral output to match our needs? We do.
