  • Lamp for a precision approach path indicator
    Patent number: 12291353
    Abstract: A lamp for a precision approach path indicator comprising at least two radiation sources emitting electromagnetic radiation of different wavelengths, a beam of radiation of a first wavelength and a beam of radiation of a second wavelength, and a partition for separating the beam of radiation of the first wavelength from the beam of radiation of the second wavelength. The lamp is further provided with an offsetting element that offsets at least one of the beams essentially towards the other of the beams by a width to compensate for the obstruction created by the partition.
