Relative spectral distribution of incandescent lamp

Relative spectral distribution of high-pressure discharge lamp

In most simulation modules, the quality of the colour rendition cannot yet be reproduced because the appropriate data and programs are not available. Rather than calculating the entire visible spectrum of light, the software currently only calculates certain segments: red, green and blue. Since the various types of lamp do not have a uniform spectrum, the result is different colour renditions that are not covered by the simulation programs. Consequently, specifics on the colour rendition of illuminated textiles in a shop, for example, are not possible with the current state of the art. Appropriate future functions would additionally require the definition of the spectral characteristics of both the light sources and the surfaces.
