摘要
A compact PAPI having a semiconductor light source and finely distribution of lights is herein proposed. The novel PAPI includes two artificial light sources each with a plurality of semiconductor emitters as well as two concave and two planar reflectors, one for each artificial light source. The concave reflectors collect light emitted by the plurality of semiconductor emitters of the first and second artificial light sources and gather the collected light to the planar reflectors as output of the PAPI.
