Comparative performance analysis of different lighting sources

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.
