Human Centric Lighting (HCL) refers to lighting concepts that take into account not only the visual but also the biological effect of light on people. General lighting with variable light colour plays a central role in such applications which are often based on the so-called circadian sequence – the spectral change of daylight from sunrise to sunset. ERCO now presents recessed luminaires with tunable white technology precisely for this purpose. As part of the Quintessence range, they offer proven product and design quality as well as visual comfort of the highest level.
Day begins with the tinge of morning dawn. At noon when the sun is at its zenith, sunlight and the light of the sky blend to form a radiant bluish white that shifts back to a warm orange in the evening until sunset. Mankind has developed according to this eternal cycle. That our internal clock and other biological functions are controlled and influenced by the spectral components in light is now considered to be standard scientific knowledge.
Human Centric Lighting (HCL) concepts aim to utilise these findings for architectural lighting to improve the well-being of people in buildings. However, the mere use of individual products is not enough: holistic HCL solutions consist of several networked components. This is the only way to synchronise and selectively control parameters such as light intensity, the direction of light and, above all, the colour temperature of the light sources.
For the central component of general lighting in such HCL concepts, ERCO now provides lighting designers with flexible and high quality tools: the Quintessence recessed luminaires with tunable white technology. These offer all the features that have made Quintessence a benchmark for downlights: for example ERCO darklight reflectors for maximum visual comfort, aluminium housings designed as heat sinks for optimum thermal conditions and mounting rings for quick and easy installation with covered mounting or optionally for installing flush with the ceiling.
