Lighting devices refer to the significant element of many technical systems including the roadway, housing, industrial illumination, lighting systems for vehicles. The optical systems for light-emitting diodes are considered. The peculiarities of use of secondary optical elements in the form of lenses and reflectors are analyzed in order to obtain the different diagrams of radiation directivity of light-emitting diodes in space. The requirements specified for the optical elements are formulated. The peculiarities and problems connected with the estimation of secondary optical systems are considered.
