“…Thus, a 46% saving in terms of electricity cost is achieved by simply replacing the luminaire, which means (considering the overall electricity+maintenance cost) a 32% saving per year per each fixture. This estimation, confirmed also by [13], is prudential as several papers claim that higher reductions in energy cost can be achieved [64,74]. In particular, Valentová et al published a report on 106 test-beds from 17 European countries, showing an average energy saving of 59% compared with that of the original installation [5].…”

“…Starting from the first papers on this topic [15][16][17][18][19][20], different remote-control systems have been proposed, which rely on the exchange of information between light fixtures and a Control Center, the latter being the management headquarter for the lighting service. An overview of early researches concerning smart street lighting systems is presented in [13].…”

“…Furthermore, dimming can enhance the lifetime of LED luminaires due to a reduced risk of overheating, which is the principal cause of abrupt LED failure." In this regard, results from a global trial of LED streetlights show that, when coupled with smart controls, LED fixtures can deliver electricity savings of up to 80% over classic lighting technologies [13].Beyond energy savings, since each smart streetlight needs to be provided with bidirectional communication capabilities, an ubiquitous city-wide communication network arises from the lighting infrastructure, reaching every location where a smart light fixture is present. Apart from enabling the remote control of each luminaire independently of the others, as well as the remote monitoring of its functional parameters (power consumption, lamp temperature, electrical parameters), this widespread network allows to collect data gathered by sensors (air pollution, vehicular traffic, water flooding, etc.)…”

Street lighting characterizes many smart city initiatives around the world. In fact, significant savings can be achieved by not only replacing traditional luminaires with low-power LEDs, but also providing streetlights with smart light controllers and network connectivity, allowing the introduction of a sensible light intensity management and reduction of maintenance costs. Moreover, if designed with a far-looking view, smart lighting infrastructure could also support city-wide Internet of Things services, becoming key enablers of the smart city revolution, also in the 5G perspective. In this paper, we provide a thorough discussion on network architectures and communication technologies that could be adopted for smart public lighting applications, showing their benefits and downsides. Starting with significant activity on research, implementation and in-field testing, we also outline the steps required for the deployment of a smart public lighting infrastructure, each discussed in accordance with the network topology considered. Finally, we introduce some additional services that a smart public lighting infrastructure could support and discuss the benefits that would arise from integration with the upcoming 5G cellular network.In this framework, the momentum for smart public lighting is mounting, as several trials and large-scale implementations showed their effectiveness [5]. In particular, LED fixtures are expected to dramatically reduce urban electricity costs, now due to street lighting for a share of 40% [6]. Smart luminaires will dynamically adapt lighting to actual needs, for instance lowering the lumen output when there are low traffic volumes and good visibility conditions are detected.Important references in this regard are the "GPP Revision of the EU Green Public Procurement Criteria for Road Lighting and traffic signals" [7], authored by the Joint Research Centre (JRC) of the European Commission, and the CEN/TR 13201 lighting standards [8][9][10][11][12], which define how to properly design lighting systems. As reported in Reference [7], "due to the multiple benefits of dimming, dimming controls must be installed in all cases unless, in exceptional circumstances, it can be demonstrated that the total cost of ownership would increase by installing dimming controls. The EN 13201 standard itself [8][9][10][11][12] recognizes that the required lighting levels are dynamic in nature and an appropriate lighting level at all times can only be ensured with adequate dimming control during off-peak hours. Dimming has obvious environmental benefits via lower energy consumption and reduced light pollution. Furthermore, dimming can enhance the lifetime of LED luminaires due to a reduced risk of overheating, which is the principal cause of abrupt LED failure." In this regard, results from a global trial of LED streetlights show that, when coupled with smart controls, LED fixtures can deliver electricity savings of up to 80% over classic lighting technologies [13].Beyond energy savings, since each smart streetlight n...

“…But, nowadays, new technology, which is called smart [1], intelligent [2],or dynamic [3] street lighting system has been developed. It is emerged as economic investment plan and adopted by governments and municipalities to reduce energy consumption by switching the lamps ON/OFF at the right time; that also, it is dynamically switching the lighting level at each light point into light output required by the lighting standards at fixed time and/or based on the activity in the area [3][4][5]. Integrated Dynamic Street Lighting System (DSLS) are available in the world in many methods for more details [1][2][3][4][5].…”

This paper studies the manner of energy consumption in Libyan street lighting systems and general road section. It also suggests proposal system with two cases of operation for an attempt to apply the energy saving program by adopting an optimum method in order to decrease the demand of energy in this section and to reduce the use of uneconomic equipment.The proposal system in this paper introduces the Light Emitting Diode (LED) street lighting technology to be used instead of traditional luminaries High Pressure Sodium (HPS). The proposed system is divided into two cases. The first case discusses the replacement of traditional luminaries (HPS) with energy saving luminaries (LED), while second case explains how integrating control node (dynamic dimmer) into LED in order to dim output lighting in streets will save more energy.This study reaches a result that a significant amount of energy of %47 (about 1092.23 GWh/year) of total energy consumed in street lighting sector could be saved if first case is applied. Moreover, it suggests that more energy of %58 (about 1380.02 GWh/year) of total energy consumed in the same sector cloud be saved if the second case is adopted.
