Opis:
The main subject of the research is a proposition of a luminaire optical system which allows us to illuminate building facades in a more uniform way than it is today in the case when luminaire location is close and asymmetric to the illuminated object. Firstly, the paper introduces and explains the term of floodlighting and presents luminaires that are used in floodlighting. The author casts doubt on floodlighting luminaires quality especially related to luminous intensity distributions. Certain problems arising from illuminating objects by using improper luminaires are presented and discussed. As an attempt to improve the situation, the author shows his innovative concept of the luminaire optical system. Finally, to verify the proposed luminaire optics, the author has made a comparison of his conception with two other luminaires.

Opis:
The development of technology and design of light management systems remains dynamic. Among all the benefits offered by these systems, the most valuable might definitely be the possibility of saving energy consumption. Knowing the value of energy savings is the key factor that users need to know before deciding to use a lighting management system (the type of light management system). For this purpose, it is useful to simulate the operation of the lighting control system, for example in the DIALux program. Such simulation helps evaluate potential savings in electricity consumption using the proposed lighting control system. In the DIALux program, it is possible to change the luminous flux value of luminaires. In such a case, it becomes possible to semi-simulate the light management system’s operation as we don’t receive actual information on reducing installed power of the lighting system during reduction of the luminous flux value of luminaires. This article shows what type of technical data are important to use for the DIALux program to properly and accurately simulate light management systems and to receive accurate data on energy saving. It also presents the results of photometrical and electric parameter measurements (Φ – luminous flux, P – power, PF – power factor, THDi – total harmonic distortion of current). The article discusses the power control characteristics obtained on the basis of these measurements and explores the source of differences between simulation of energy saving calculations and real measured energy savings. An existing lighting control system installed in an office reception area was used to compare calculations with the real value of energy consumption reduction. The impact of electronic power and control systems on electrical network parameters is also an important problem mentioned in this article. It also explores the effect of power regulation of LED luminaires and LED modules on the value of the power factor and total harmonic distortion (current) value (THDi).
