With the Eye of a Sensor
With ”HelioJet” Spectrumcc, SCHOTT and Lufthansa Technik are introducing an innovative LED cabin lighting solution that renders light in a stable and homogeneous manner. For the first time ever, special sensor technology imitates the sensitive color perception of the human eye.

Light and colors have a profound effect on how we feel and even our ability to judge situations. If we perceive the lighting inside an airplane to be perfect, we will view the cabin as a whole as being of high quality. ”Often we don't even notice that our moods are directly related to the current lighting conditions. Our eyes, on the other hand, are extremely sensitive and register differences in color. Our brains immediately assess the results as being comfortable or uncomfortable,” Dr. Armin Plichta, General Manager of Transportation at SCHOTT Lighting and Imaging, explains. The new LED cabin lighting solution ”HelioJet” Spectrumcc (Color Control), developed by SCHOTT in collaboration with Lufthansa Technik and the sensor manufacturer MAZeT, leverages these scientific findings. This solution is based on a special optical light guide made of glass at the ends of which four LEDs – red, green, blue and white (RGBW) – each feed colored light. Up to three of these rods form one ”HelioJet” unit. Before they are emitted, the individual primary LED colors are mixed into a desired even color shade inside the light guide – an advantage over conventional LED strips that are unable to fully hide their inhomogeneous light point design despite indirect guidance of the light and diffusers.

Precise sensor and control technology measures and regulates the main color shade of each LED across all of the ”HelioJet” units. Photo: SCHOTT
