A lighting device is provided that includes an LED and an NIR filter for a control panel or a display, which does not interfere with a night vision device. The light of the LED is in an area of u′>0.19 and v′>0.46 of the u′v′ diagram of the CIE-LUV chromaticity diagram. The NIR filter exhibits descending light transmittance between 500 nm and 800 nm. The thickness of the NIR filter is chosen so that a sufficient blocking effect is provided in a range of wavelengths between 600 nm and 800 nm, so that the color coordinates of the filtered useful light are in an area with a radius of 0.04 around coordinates u′=0.19 and v′=0.49 of the u′v′ diagram.
