DEVELOPMENT AND STUDY OF THE MODEL FOR THE LIGHTING DESIGN OF HIGHWAY ILLUMINATION IN THE LIGHT-IN-NIGHT ROAD SOFTWARE
The PURPOSE of the article is to consider the possibilities of modern software Light-In-Night Road for the lighting design of highway illumination; to develop a model of the lighting design on example of a straight section of the road taking into account the characteristics of fixtures and current regulations and standards for illumination; to study the developed model of the road in terms of compliance of the illumination level and other lighting parameters with the Russian norms and industry standards. METHODS. A three-dimensional model of the section of the A category road is developed to study the lighting system. Domestic GALAD models with LED lamps are used as fixtures. The method of light-collection efficiency is used for illumination calculation. The results are generated in a table form by a protocol module Light-In-Night Road. To display illumination zones on the roadway and sidewalk the representation of the calculation results in a three-dimensional model of a fictitious color diagram is used. RESULTS. The developed model of the section of the A category road allows to study the street lighting systems equipped with any kinds of fixtures including modern LED lamps. The illumination analysis performed in this program agrees with the standards and regulations of the Russian Federation for the illumination of roads of different categories. CONCLUSION. The results obtained can be used in teaching the procedures of highway lighting calculation when designing power supply systems in cities, districts, major industrial enterprises with the use of the most advanced LED lighting fixtures based on existing industry standards.
