Abstract

Light guiding plates coupled with fluorescent lamp are modern solutions in construction of general-purpose luminaries. Thanks to such a solution, large illuminating surfaces are created, characterized by constant luminance. Providing that the total height of such a device is relatively small, fluorescent lamps with high luminous efficacy might be used successfully. The problem related to the influence of the fluorescent lamp light color on attenuation of the luminous flux in the light guiding plates is relatively seldom approached. Theoretical calculations of the absorption index are presented in the paper, along with their verification against exemplary light guiding plates made from methyl polymethacrylate and type T5 fluorescent lamps with varying light color.
