The peculiarities of extra narrow-angle LED spotlight development for accent
lighting have been described. The optical layout of lighting fixture was developed. The
mathematical model that can be used to calculate the optical and geometrical parameters
of extra narrow-angle spotlight have been developed. The two actual samples with output
lens with the diameters 50 and 100 mm were developed and tested. The results of
computer simulation and actual testing the spotlight samples were compared.
