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. © 2013 Optical Society of America.

The article considers parameters of light-emitting diode modules (LEDM) with a thermosiphon heat pipe for luminaires with a luminous flux of 10-30 klm intended for external illumination, including illumination of streets highways (class A1 of category A). The results of preliminary tests of LEDM experimental samples of 35-100 W power are presented. A version of a road luminaire formed of several such LEDMs is considered.
