Spectral radiation distribution

Light is nothing more than wavelengths, whereby each wavelength has a different spectral color. White light, on the other hand, is made up of several spectral colors with different intensities. Depending on the type of lamp, the spectral radiation distribution also changes, since not every light source has the same spectral colors. However, the more colors the spectrum of a lamp has, the better its color rendering.

For example, temperature spotlights such as incandescent lamps have a very continuous color spectrum, which covers a variety of colors. In the case of fluorescent tubes, on the other hand, some colors are more represented than others, which makes their spectrum less continuous, and in daylight the short -wave blue spectral colors dominate. The LED technology now manages to reproduce all spectral colors. Each lamp has a typical specific spectral radiation distribution, which is important for color rendering.
