The Road

High-quality street lighting improves visual perception of the road and provides for a significant decrease in the number of road accidents. It has been established that the total number of accidents can be reduced by 30% for national roads and by 45% for especially hazard areas (e.g., at intersections). Doubling of the average luminance of the road surface significantly reduces the number of accidents in the dark and twilight. Sufficient street lighting contributes to: reducing electricity consumption; decreasing operating costs; improving the environmental situation; promoting business, tourism and investment activity; decreasing the number of criminal offenses. The analysis of recent research and publications helped choose the best European practices which can be used to improve the outdoor lighting in Ukraine. The street lighting network is continuously growing and being modernized. Different types of light sources are being used in the network to illuminate the city. Today, high-pressure lamps (HPS) are leading. They are increasingly replaced by LED light sources. Not a small share is accounted for by metal-halide lamps. The smallest number of light sources in the street lighting system, high-pressure mercury and compact fluorescent lamps (CFLs). To increase the efficiency of the street lighting system and reduce energy consumption for its operation, measures for its reconstruction and modernization are required. For this purpose, it is necessary to address the following problems: high level of obsolescence and physical wear and tear of system elements; inefficient use and high losses of electricity at the stages of transportation and consumption, due to the use of obsolete and worn-out equipment; suboptimal distribution of the utility capacity, which leads to ineffective use of the existing lighting system; low efficiency of the street lighting control system, due to the lack of electric meters and remote monitoring and control of the street lighting. Introduction of energy-saving types of light sources is one of the ways to modernize the existing street lighting system. It is necessary to replace old lighting fixtures, which have already exhausted their life span, by new energy-saving light sources (replace CFLs by LEDs), use automatic control systems. All this in turn will help reduce energy costs by 60%. To improve energy efficiency of the street lighting system, it is also recommended to carryout the replacement of electromagnetic ballasts by electronic ones. The employment of electronic ballasts, e.g., in case of using HPS 250 lamps, allows to save approximately 255 kWh/year. Considering that the price per kW of electric energy is UAH 2.68, one luminaire helps save the amount of UAH 683.4 per year.

Switching Method

Energy-saving street lighting (ESSL) system is one of the promising approach to support smart city in the future. The technology that evolves with the advance in low energy microcontroller and wireless communication has become the foundation in the development of ESSL system. This paper presents initial development for ESSL system focusing on the Malaysia environment. The system utilizing Waspmote as a main part of sensor node, zigbee for communication and PIR sensor for motion detection. Deployment of sensor node at real environment also been discussed in this initial develompent. The sensor node can be used to control the brightness of the street light and the developed system found to save energy through the switching method of street light.

This paper is concerned with the automation in street lighting system. The projected work describes the automatic working of street lights according to seasons and timing of a day. The system comprises of microcontroller, GPS, RTC to implement the work. Projected work overcomes the drawbacks of previous systems like is error in timing, by using the information about time with the help of GPS. Microcontroller takes the data and accordingly operation of lighting on/off is performed. RTC comes into action in case of any interruption. The system works without any operator. The developed have some advantages like energy saving as lights are on according to timings and increase in life of luminaire.

The Cost

The light emitting diode (LED) street lighting systems based on solar photovoltaic technology have been used for some time. In this paper, we present an analysis aiming at assessing the feasibility and economic performance of a solar-powered street lighting system for a 1km road. The present study introduces the architecture of a classical solar-powered LED street lighting system and estimates the total investment cost for a 1 km highway with 2 lanes. The cost comparison of solar-powered LED lighting and sodium lamps using grid was carried out. The calculations show that the energy saving effect of solar-powered LED lighting systems is obvious but the initial investment of solar-powered LED systems is more than sodium lighting systems using grid. The investment cycle is about 2.2 years under the current conditions.

Proper street lighting has psychological, ecological and economic functions. Not only does it provide safety in settlements at night, but it also makes streets friendlier. Inadequate quantity and quality of street luminaries can cause troubles in the ecosystems of settlements. Public lighting management is the responsibility of local governments, and therefore it matters how much the operation and maintenance burden the budget. The modernisation of the obsolete street lighting system and the installation of a reliable and energy-saving (cost-effective in the long run) system is taking place in more and more places. Large cities (domestic cities with county rights) deserve special attention due to the concentration of the population, functions and through them the concentration of environmental impacts.
