%X the luminous output of the lamps in road lighting decreases at a rate that depends on the type of lamp, the ballast system and operating parameters. this cause of depreciation is considered from the design stage from the maintenance factor, once established maintenance program. this paper reviews the different sources of information available, while valuing the outcomes of the major investigations that have been used in recent times. it recognizes the data provided by lamp manufacturers as the most reliable source. technological advances introduced into the manufacturing process of these lamps in addition to extending its useful life also deliver higher lumen maintenance which potentially can increase the energy efficiency of these systems. in addition to other important advantages, leds has a good maintenance of their luminous flux the authors approach the trial elements and techniques for the use of curve fitting tool. mathematical models to predict this depreciation rate are offered.
