Ceiling

Ceiling illumination to emphasise room height

With ceiling illumination, either light is shone to illuminate the ceiling in its own right or the ceiling is merely used as a reflector for general lighting. The ceiling is primarily emphasised, when it has an intrinsic communicative value, e.g. due to architectonic structures. Illuminating the ceiling to provide indirect general lighting requires it has a high reflectance. It should be noted the ceiling will then be the brightest surface in the room and will therefore be emphasised.

The luminaires for ceiling washlighting can be suspended from the ceiling or mounted on the walls. As linear luminaires, light structures act as independent architectural elements, whereas ceiling washlights are more secondary to the architecture. Light structures emit diffuse light with low brilliance.
The choice of luminaire type is dependent on the ratio of room area to room height. In low rooms with large floor areas an even illumination of the ceiling using light structures presents itself as the best option. Ceiling washlights require a large distance from the ceiling due to their asymmetric light distribution.

The prerequisite for ceiling illumination is a sufficiently high room in order to achieve an even distribution of light. Ceiling washlights should be mounted above eye-level. The distance from the ceiling depends on the level of evenness required and should be at least 0.8 m.

Luminaires for lighting support structures can be mounted on the structure itself, on the walls or in the floor. A washlighting illumination adds emphasis to the whole ceiling surface. Narrow-beamed luminaires accentuate the support structure in particular.
The selection of the type of luminaire is dependent on the scale and the proportion of the support structure. Spotlights can also be attached directly to components of the support structure. The arrangement of the luminaires should be oriented around the design of the support structure. Ceiling washlights require a large distance from the ceiling due to their asymmetric light distribution.
