Abstract
Various variants of LED modules for local illumination are analyzed. The possibilities for approximation of LED luminous-intensity curves and for calculations of these curves in the TracePro system are considered. A method to calculate the illuminance of a 2D area via the 1D distribution of the illuminance along a line is proposed. A comparative analysis of the uniformity of the illumination and of the energy consumption is performed in the case when LEDs with different concentrations of luminous fluxes are employed. A possibility for rotation of LEDs via various optical systems for scattering and focusing of luminous fluxes is considered. In addition, the possibility of improving the uniformity of illumination through a decrease in the size of LED modules and a variation in the current of rotated LEDs is analyzed.
