Continuous LED spectrum (3000K)
In daily life, continuous spectra such as the warm white light of incandescent lamps or the neutral white light of daylight are our references for the natural rendition of colours. A wide, balanced spectrum such as that of ERCO warm white LEDs achieves authentic, familiar colour rendering on exhibits and has a low damage factor.
Continuous LED spectrum (4000K)
In exhibitions with a strong ingress of daylight, spectra creating similar colour impressions have proved their worth. Here again, a bright balanced spectrum is important for faithful colour rendering.
Modelled LED spectrum (2700K)
By combining differing LEDs and via the composition of the phosphors, spectra can be modelled that have a high colour rendering index but that lessen the authentic visual experience of art due to the oversaturation of individual colours. For example, high radiation intensity in the red spectral range gives red tones an especially intensive appearance. In such situations the human eye sometimes has difficulty differentiating between individual nuances of red.
RGB LED spectrum (2700K)
Superimposing red, blue and green colour stimuli generates a white colour impression. However, the white light of RGB LED luminaires has large gaps in its spectrum. In accordance with the three spectral colours contained, only colours with red, green or blue components can be rendered. An RGB spectrum is therefore unsuitable for museum lighting. Only a further white LED (as used in RGBW luminaires) enables a balanced spectrum, the light colour of which can also be modified.
