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.

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.
