COMPARATIVE PERFORMANCE ANALYSIS OF DIFFERENT LIGHTING SOURCES

Abstract

We consider four different types of bulbs: incandescent, fluorescent, halogen and LED. Their
positive and negative characteristics are given. In particular, typical schemes of their connection are
provided. Charts of dependence of the light flux on the capacity of various kinds of lamps are drawn
up. Their analysis is performed to identify the most effective light source. For this economic calculation
of electricity costs during one year, taking into account the guaranteed lamp life and its price
was performed. We studied the emission spectrum of the considered types of lamps and revealed the
variants closest to radiation of the sun as the most comfortable for eyes. The ripple factor of different
lamps that negatively affects general human health was considered. The obtained results were
compared to SP 52.13330.2016 and allowed us to come to a conclusion that LED lamps are not only
the most economically profitable and reliable, but also provide the most comfortable conditions for
living quarters, especially in the offices and reading rooms, and are the optimal light source in case
of proper design and location.
