HIGHWAY LIGHTING RESEARCH

THE DEVELOPMENT OF THE USE OF SODIUM VAPOR AS AN ILLUMINANT AND ITS APPLICATION TO STREET AND HIGHWAY LIGHTING IS DISCUSSED. THE USE OF THIS NEW SOURCE OF LIGHT WILL MEAN MANY CHANGES IN PRESENT PRACTICES AND THE RESEARCH ENGINEERS ARE WORKING ON THE PROBLEM OF ITS MOST EFFICIENT USE. THE SODIUM LAMP DERIVES LIGHT FROM THE PASSAGE OF AN ELECTRIC CURRENT THROUGH A VAPOR OF SODIUM WITH A SMALL QUANTITY OF NEON GAS. WHEN THE CURRENT IS TURNED ON THE LAMP FIRST GLOWS RED AS THE NEON GAS CARRIES THE ARC AND THEN TURNS GRADUALLY TO A GOLDEN YELLOW AS THE SODIUM VAPORIZES. THE PROCESS IS FULLY DESCRIBED. THE APPLICATION OF THE LAMP TO HIGHWAY LIGHTING IS CONSIDERED. THE RELATION OF VARIOUS KINDS OF ROAD SURFACES TO LIGHTING PROBLEMS IS BROUGHT OUT, AND THE POSSIBLE FUTURE ECONOMIES THAT MAY BE REALIZED ARE DISCUSSED. /AUTHOR/
