The rapid development of semiconductor light sources has resulted in the appearance on the illumination-engineering market of powerful LEDs nominally from 5 to 50 W. High luminosity, a wide range of color temperatures, long service life, the possibility of program control, and acceptable price—these are the advantages of LEDs that make it possible to convert from devices with traditional light sources to energy-efficient LED devices. The efficiency of a lighting device used in a specific illumination task is determined not only by the luminosity, but also by the efficiency of its optical part, as well as the design of the lamp housing and the cooling system. This paper presents techniques for carrying out optical calculations and optimizing the optical system, using LED lamps as examples. A heat-pipe cooling system for powerful LEDs is analyzed.
