STUDY OF OPTICS FOR LED LIGHT DEVICES AND METHODS OF ITS COMPUTER MODELING

Abstract

The article discusses optical systems for LED lighting devices, the principles of the propagation of rays in lenses of various designs. 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. Considered the features and problems of calculation of the secondary optical systems. Problems and prospects of application are considered, research and computer modeling of optics, which is used to form the required light distribution in LED light devices. Computer modeling technologies and the mathematical methods that underlie them determine the possibility of developing such optical systems in lighting installations. The article considers the numerical Monte Carlo simulation method, which allows one to organize ray tracing modeling in optical systems. The TracePro software package for modeling and research of lighting devices and their optical elements allows you to automate the stage of their calculation and design, this significantly reduces the cost of developing new products. The prototyping of three-dimensional models of lens systems opens up great opportunities for manufacturers of optics for LEDs, allows research on prototypes planned for production of serial products.
