<span lang="EN-US">A good and proper street lighting system on campus indirectly supports teaching learning activities. However, these conditions still need to be developed at the Marine Fisheries Polytechnic of Kupang due lack facilities. Therefore, a solar was designed considering potential energy in this region. The design is carried out by measuring for year, analyzing potential, econ...

Objective. The task was set to analyze the current situation in relation quantitative and qualitative state of a comfortable urban environment at night, namely lighting pedestrian zone along Kubanskaya Street Astrakhan. Method. study is based on analytical design methods. Result. During calculations, areas were identified that did not meet standards for night. To achieve this goal, project has ...

Light Emitting Diodes (LEDs) with their current performances have been proved to be the most suitable solution for street lighting applications. Nowadays, a topic of interest in this context is the design for electronic driver in order to take the advantage of LEDs performances. However, requirements such as high power factor, long life time, accurate current control and high efficiency pose ch...

1. Much concern has been expressed about the ecological consequences of night-time light pollution. This concern is most often focused on the encroachment of artificial light into previously unlit areas of the night-time environment, but changes in the spectral composition, duration and spatial pattern of light are also recognized as having ecological effects.2. Here, we examine the potential c...

The costs related to the operation of street lighting can be significant expenses for municipalities; therefore, it is very important take advantage opportunities improving energy efficiency. In this paper, authors studied effects implementation efficiency measures in a system. Different scenarios, including replacing luminaires, inefficient lamps, and installing dimming control system, are ana...
