Impact of Light on Environment and Health

THE AUTHOR COMMENTS ON THE PUBLIC LIGHTING SYSTEM IN A SQUARE IN MADRID, 15000 SQ M IN EXTENT. FOR TECHNICAL AND AESTHETIC REASONS, THE LAMP POSTS USED COMPRISED SIX SOURCES OF LIGHT DISTRIBUTED IN AN ASYMMETRIC FASHION, USING 1000 WATT HIGH PRESSURE SODIUM VAPOUR LAMPS. THE DESIGN CALCULATIONS AND THE RESULT OF LIGHTING MEASUREMENTS (BY MEANS OF LUXOMETER RECORDERS MOUNTED IN CARS AND INDIVIDUAL MEASUREMENTS) AND MEASUREMENTS OF LUMINESCENCE, MEASURED BY THE ROSENHAGEN TYPE OF LUMINANCE METER. THE LEVEL OF UNCOMFORTABLE GLARE IS SATISFACTORY AND, FROM THE ECONOMIC POINT OF VIEW, THERE IS A SAVING IN BOTH ENERGY CONSUMPTION AND MAINTENANCE WHEN COMPARED TO CONVENTIONAL INSTALLATIONS. THE SYSTEM HAS OTHER ADVANTAGES SUCH AS SAFETY, ILLUMINATION OF THE ENVIRONMENT, BETTER VISIBILITY IN FOG AND SAFE MAINTENANCE. DETAILS OF FOUNDATIONS AND SUPPORTS USED ARE GIVEN.
