Healthy Light - LED Technology for Health and Care Applications

Healthy Light - LED Technology for Health and Care Applications

The right light, at any time during the day or night, is absolutely essential for health and well-being especially in health and care applications. Peter Haumer, Head of Technical Sales at Lumitech/Kiteo reveals why, besides full spectrum and high color rendering, mimicking real daylight conditions with extended daylight curves, a direct and an indirect component (CCT 1.800–16.000 K), are essential. The article discusses the benefits that can be derived from special colors for medical staff, patients and residents.

Well-Being, Light and Exhibition Lighting

Well-Being, Light and Exhibition Lighting

Commentary from LpR 71: Well-being is the state of feeling healthy and happy, a good or satisfactory condition of existence, including the emotional and psychological sphere. In 1810, Goethe published a theory based on a human-based approach, combining visual appearance with harmony, culture, sensations and psychology. His color wheel was entitled "allegorical, symbolic, mystic use of color" and was composed of six hues, i.e. red (the beautiful), orange (the noble), yellow (the good), green (the useful), blue (the common) and violet (the unnecessary). The position on the wheel was harmonically relevant and in particular the colors in opposite position generated a strong psychological contrast and were called "opposite colors". Primary colors were yellow, blue and red, and the opposites were green, violet and orange, respectively. Goethe's wheel and the particular matching of opposites soon became popular and was used by the Impressionism movement, especially by Vincent van Gogh and Claude Monet. In this artistic movement, the special impact given by the combination of opposite colors were deliberately aimed to create special psychological effects and sensations.

WHITE PAPER - The Calibration Traceability Chain of a Photometric LED Test System

FluxGage is a LED luminaire tester and provides a small and cost-effective solution for testing LED luminaires in 2π geometry. The black measurement surface and the lack of multiple reflections make the system much more predictable and allow using information about the DUT such as size, beam angle and surface reflectivity, to calculate correction factors.
