The effect of operating position of the light source on the photometric parameters

Abstract

The theses discusses how operating position and ambient temperature affect electric light sources. For the purposes of this theses, the analysis of light radiation, the description and the principle of taking measurements of light quantities are included. The work also contains the principle of function, construction and parameters of light sources. For each light source a hypothesized impact of the operating position of the light source and the impact of ambient temperature variation on radiated luminous flux are stated. For selected light sources a measurement of the impact of the operating position on the sources’ photometric parameters was taken. The output measurement data are being compared to the theoretical hypotheses. The conclusion of the thesis describes suggested recommendations for the operation of light sources based on both theoretical and practical parts of the thesis
