Fitout articles and articles of equipment for kitchens or laboratories with a lighting element
A fitout article or article of equipment for a kitchen or laboratory is provided. The article has a lighting and separating element. The separating element in a region of the lighting element has light transmittance of at least 0.1% and less than 12%. The lighting element in the interior emits light that passes through the separating element and to the exterior. The separating element has a glass or glass-ceramic substrate having a CTE of 0 to 6 ppm/K and has a colour locus in the CIELAB colour space with the coordinates L* of 20 to 40, a* of −6 to 6 and b* of −6 to 6. D65 standard illuminant light, after passing through the separating element, is within a white region W1 determined in the chromaticity diagram CIExyY−2° by the following coordinates: White region W1 x y 0.27 0.21 0.22 0.25 0.32 0.37 0.45 0.45 0.47 0.34 0.36 0.29.
