Paper Abstract

LEDs have many advantages over traditional lighting, such as high brightness, small size, broad range of wavelengths being emitted and ability to be placed with high density over flat or even-shaped surface. This offers promising choice for many industrial and consumer applications and especially important for machine vision applications, where bright and homogeneous illumination offers better visibility of features of interest. This can be obtained both with multicomponent source configuration and analysis of distribution of optical energy density and color on an illuminated surface. Required illuminating properties are produced by multicomponent source with certain structure and power configuration. In this paper it is shown how to obtain required color and energy distribution on the surface of interest by varying parameters of multicomponent source (matrix dimension, the distance between elements in the matrix, the distance between the source and illuminated surface, etc.). Superposition of individual elements spectra is also taken into account. This paper has proposed technique of the RGB multicomponent source simulation, which provides homogeneous illumination on a flat surface of interest both in optical energy density and color. The ripple of luminance on the surface shouldn't exceed the value of 2%.
