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.

The purpose of this work is to study the state of the problem of transition of local lighting fixtures in Ukraine to LED counterparts. At present, there is almost a complete abandonment of the use of traditional light sources, due to the low light output of these sources, low service life, environmental considerations, and so on. However, the main requirement for lighting fixtures of any type is the compliance of their light distribution with the visual tasks that will be assigned to them during operation. As for most outdoor and indoor lighting fixtures, they are, in fact, certified, and their light distribution is given in one form or another either in the passports of the device, or in technical descriptions of relevant products on the websites of manufacturers or in catalogs. As for local lighting fixtures – table lamp fixtures, such information is not provided to the buyer. However, there are generally accepted recommendations for the light distribution of such lamps. Namely - the light distribution should be uniform and direct illumination on the work surface should be close to 200 lux. If you deviate from these requirements, the consumer may face problems such as visual impairment and stooping. As the volume of production of local lighting fixtures is significant, the authors set themselves the task of understanding whether modern models of these fixtures meet these standards. The paper presents data on the systematic study of the light distribution of local lighting fixtures for a considerable period of time. It is shown that the first samples of LED lights did not meet the requirements for their light distribution, which was confidently provided by lights based on compact fluorescent and halogen lamps. But gradually the light distribution of LED-lights approached the cosine and today for the vast majority of LED local lighting fixtures on the market it can be stated that their light distribution is absolutely adequate and further use of traditional light sources for local lighting can be completely stopped. It is also noted that the vast majority of modern table lamps are equipped with dimmers, what allows to flexibly adapt local lighting modes to solve specific visual problems in addition to other energy savings.
