Features of the development of LED spotlight for local illumination of extended objects

摘要

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