Deviations in luminous flux and hue occur during LED production, but color compensation technology allows luminaire manufacturers to provide color-constant products for demanding applications, writes Thomas Schielke of ERCO Leuchten.

Lighting designers have always used colored light to add emphasis or provide atmospheric effects. This was done using colored lamps or luminaires with color filters, but thanks to electronically controlled RGB color mixing luminaires it is now possible to produce any color of light with LEDs.

Using color compensation, the luminaire manufacturer is able to compensate for the deviations in luminous flux and hue due to the manufacturing tolerances of LEDs, and thus to satisfy the highest demands of designers for uniformity, e.g. for colored wallwashing (see figure 1).
