Colour mixing in the colour triangle

Coloured lamps or sheathing the T16 light source in coloured film produces coloured light. Special coloured films that emit especially intense, pure light were developed for CIELOS. They are available as accesso- ries in the three primary colours red, green and blue. Any other coloured film suitable for use in luminaires can also be used. The luminaire lives up to the promise of its elegant external appearance. The low-profile front made of glass and sheet steel conceals state-of-the-art technology. All the electrical components are integrated in the basic unit – the fully Intermediate hues can be mixed by using lamps of various col- ours (red, green, blue) or several light colours (warm, intermediate or cool white).

Multicoloured

Because of their high satura- tion, the three primary colours red, green and blue (RGB) open up a wide dynamic range and the possibility of producing any desired colour within the primary-colour tri- angle by mixing colours. Add- ing the three primary colours together produces white. The multicoloured CIELOS’s strength lies in its vivid col- ourfulness and radiance.

Monochrome

Both options are possible here: either select a light colour in the white range of the Planckian curve (white light source with appropriate colour temperature) or one of the primary colours red, green or blue.

Bicoloured

Smooth to the touch, high-quality appearance, strength, no yellowing and no greenish hue, no electrostatic charge and no fire risk: its countless aesthetic and functional advantages make glass the architect’s material of choice. Bicoloured luminaires produce all the colours located on the line that connects two colour locations (linear mixing). Results are highly variable, depending on the particular combination.

stance, from a warm 2,700 K to a somewhat cooler 6,000 K. White plus one colour Combining white with one colour makes it possible to mix white light to any selected colour. Colour plus colour Mixing two colours makes it possible to obtain mixtures located on the line that con- nects these colours in the colour triangle. enclosed double diffuser cham- ber and the layer of glass on top of it distribute light evenly and uniformly. Even CIELOS with a mounting height of just 80 mm achieves a high level of uniform- ity, thanks to clever arrangement of the light sources.
