Abstract

This paper presents the reliability analysis of lighting systems, which is the first of its kind in illumination engineering. The designed lighting system is modeled as a series-parallel system with respect to reliability analysis and conditional probability technique is applied. The enumeration of the different types of failure states of the luminaires in a row are listed and the probability of failure of the row of luminaires is evaluated. The probability of failure of each row is used to determine the probability of failure of the designed lighting system. The Light Loss Factor and the Ballast Factors are used as the reliability indices of luminaire. The interior lighting of a tobacco industry is considered for the analysis which consists of 121 luminaires of 400 W High Pressure Metal Halide (HPMH), Tubular lamps with non-integral, High Bay luminaire and Universal reflector. The reliability of the designed system is found to be 96.3 percent reliable during future operation.
