Abstract. 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.
Keywords: LED, pencil beam, extra narrow-angle spotlight, LED spotlight.
