Our town under the stars: Do we sleep better after the change of the urban lighting? Nika Sraka, Maja Hozjak i Katarina Hozjan Valentina Pirc Mezga i Maja Labaš Horvat Srednja škola Prelog, Prelog 1. SUMMARY A few years ago, we conducted a survey on light pollution in our region and we got more closely acquainted with the types of existing street lighting fixtures and their impact on the population. We decided to resume the previous project because in the meantime, most streets had their lighting replaced. We decided to conduct a survey at the school level and examine the students and their families about observing the differences after changing the lighting. The basic research questions we have asked were how does the lighting affect our dreams, driving and visibility of constellations. In this project, we used the „GLOBE at night“ database. Our project is of interest to company Energy + from Ludbreg, which is engaged in the production of LED lighting, and the association "Eco Lighting" from Zagreb. We conducted our research in the period from 6th January 2018 to 19th April 2018. The results have shown that the change of lighting is good for our dreams, for better driving and better visibility of the constellations. We conclude that people are sleeping better, the number of road accidents in rural and urban areas have decreased and the visibility of the constellations is greater.
