Computer modeling and calculation of LED lighting systems

The article describes the optical system for the light-emitting diodes. Analyzed the features of the secondary use of the optical elements in the form of lenses and prisms for different LED emission patterns in space. Formulated the requirements imposed on the optical elements. The paper considers the problem of designing modern lighting devices and optical systems. Analysis of the development of lighting devices shows that the main stage in their development is the calculation of the optical system, the results of which largely determine the lighting fixtures and functional characteristics. Application and development of specialized software for the calculation and simulation of lighting devices significantly facilitates and speeds up the process of their design. The paper presents a mathematical model developed by the software system, described in the hierarchical structure of the simulation geometry of lighting devices. Building an extended triangulation grid facilitates the approximation of smooth surfaces of the optical element and the photometric body. The software package is carried out modeling of LED optical systems and luminaires based on them using surface models, ray tracing and calculation of photometric body.

Key words
