Abstract

This paper approaches the design of a smart lighting system for efficient lighting of pedestrian crosswalks on streets, using power LEDs. Starting with existing solid-state lighting - SSL (power LEDs with individual directivity diagram, lighting efficiency and color rendering index - CRI) in the paper we propose a design technique and methodology in order to find the distribution geometry of light sources (sources number, spatial coordinates, fixing angles) that simultaneously satisfy the lighting regulation requests and energetic efficiency. The major achievements are the simulations of using of a great number of LED lighting sources and of spatial lighting configurations in order to obtain of a uniform lighting of the area of interest (fig.1) and in conformity with actual standards in a specified scenario. The direct consequence of these simulations is the using of an intelligent management system of LED lighting sources that will allow the optimization of light flux in real traffic conditions of cars and pedestrians. This means the monitoring of traffic level and surrounding conditions (temperature, humidity, natural lighting etc.) in order to efficient use the existing resources.
