Abstract

This paper discusses a method for forming files in the IES and LDT formats for LED illuminator devices, based on the use of the zemax modelling medium. The file structure and the means of modelling the components of the optical part of the device are considered. A process is demonstrated for forming IES and LDT files, using as examples an industrial-type lighting fixture and a floodlight projector. The results of calculations carried out in the illumination-engineering program DIALux are compared with the use of models obtained by photometric measurements and modelling in zemax.
