“…IL lamps are also unpopular light sources, which belong to the latest generation of electric light sources of the late 20th century. Despite their extremely high durability, their relatively high price limits the range of application to the places where access to the light source is difficult (for example, due to limited accessibility to the place of luminaire installation) [5,6,11,19,27].…”

“…They have been considered among the communities of different areas such as electrical, chemical, or mechanical engineering. In the area of lighting technique, the ecological trends have also been easily visible [1][2][3][4][5][6]. Within these trends, one of the problems taken into account by researchers is the problem of light pollution, which is associated with the lighting of outdoor areas.…”

“…The areas where light pollution is easy to recognize are the green areas-for example parks, gardens, squares, or alleys. In these areas, lighting has two basic functions: functional and decorative [5,6,[18][19][20]. The purpose of functional lighting is to ensure safety for walkers; decorative lighting serves to emphasize the value of the surroundings (plants, objects, etc.).…”

The article presents the results of the studies concerning the influence of a light source installed in luminaire of opal sphere type on the light pollution effect of the night sky. It is known from literature reports that the effect of light pollution is influenced by the spectral distribution of light. Although the influence of the spectral distribution has been widely studied from different perspectives, there is still a need to study this phenomenon—for example, from the point of view of the spectral reflection properties of the ground, on which the lanterns are installed. Hence, the above-mentioned aspect was considered in the authors’ investigations. The luminaire considered has been equipped with 20 different light sources, including the latest generation of lamps (light-emitting diodes, LEDs) as well as the conventional ones. With respect to these light sources, the measurements of light distribution and spectral distribution of emitted radiation of the luminaire were performed. Having these measurement data, the simulations were carried out using the DIALux software, and the calculations were made using the specially prepared calculation tool. On the basis of the results obtained in this way this was stated that the type of light source installed in the luminaire has a significant effect on the sky glow. An important factor affecting light pollution is not only the value of the luminous flux emitted upward but also the spectral characteristics of the emitted radiation, the impact of which is most noticeable. The conclusions from the studies indicate the next steps in the analysis of the light pollution effect. These steps will be focused on extended analysis of LEDs as modern and developed light sources.

“…Nowadays, LED technology has reached levels of energy efficiency in consolidated commercial products in the range of 70-130 lm/W [5] and the latest prototypes reach up to 200 lm/W [6] with increasingly lower costs. In addition, their lifetime expectation can be up to 5-times greater than that of discharge lamps (100,000 h LED vs. 20,000 h HPS) [7].…”

LCA Case Study to LED Outdoor Luminaries as a Circular Economy Solution to Local Scale

The replacement of luminaires with discharge lamps with high luminous efficacy and long life-time LED based equipment is a reality worldwide promoted by policies that favor their gradual substitution. There is a great concern in this manufacturing industry to develop new luminaires with low environmental impact during the manufacturing and transportation processes and its end-of-life disposal (reducing greenhouse gas emissions, toxic or hazardous components, …). Life cycle assessment (LCA) is a very extended tool used to provide information on the quality and quantity of environmental impacts in the life cycle phases of any product, system, or service. This article includes all phases of the LCA analysis of a selected streetlight LED luminaire manufactured by a SME where a landfill deposit is the end-of-life scenario. In a second phase, alternatives are sought for the reuse of the most significant elements that improve its local economy. The results are classified and sorted according to the ISO 14040 standard.

“…Different methods were studied and several algorithms were developed in previous research papers in order to obtain energy efficient installations for street lighting systems. Using Sustainable Process Index methodology, a comparative study of different lighting technologies is developed in [5]. The available technologies, such as light emitting diode, compact fluorescent and high pressure sodium were analysed in order to obtain the more suitable green solutions.…”

A multi-criteria decision making approach for public lighting system selection

There are numerous and different ways to design an energy efficient street lighting system, but not always the best technical solution is the optimal economic solution as well. In this paper, we used two distinct software tools in order to obtain the optimal technical and economic solution for selecting street lighting technology. The first software used was DIALux, which is frequently applied in this field, assisting designers in choosing the most appropriate electrical installations and evaluating the technical performance of the chosen solutions. This tool determined the street lighting system variants for which there are predetermined configurations, so that the lighting parameters obtained are in accordance with the normative requirements of the lighting classes in which the roadways are included. Different ways of locating the luminaires and other parameters were changed to reach the best version that meets the qualitative requirements of the lighting technology. The second software used was the one developed by the authors, based on ELECTRE III method, which evaluated the technical solutions returned by DIALux against several criteria, taking into account the designer's preferences and constraints. The optimal technical and economic solution was obtained after ranking the variants by their performance at each criterion. The simulation experiment and the results returned suggested that the combination of the two software tools is comprehensive and effective and it can be used in this type of decisions at large scale.
