Nowadays, improve the efficiency and reduce active loss are very important target for any electric company. One of the methods to reach this target is using appropriate street lighting and tunnel lighting systems. Control of lighting, appropriate products of lighting system, and management of the luminaire dimming will used to improve the efficiency of lighting network. Studying the lamp efficiency of low pressure sodium, LED, high pressure sodium, compact fluorescent lamps, etc. Case study and calculations of active losses in lighting system of 30 luminaire are presented in this chapter. The results discuss the impact of type and number of luminaires, distance between poles, and dimming ratio on the outdoor lighting efficiency and values of active loss in lighting network which is part of distribution networks.
