Excerpt from Effect of Quality of Surface and Color Upon Absorption of Light: A Thesis
The lack of information and methods for the use of artificial illuminants in economic commercial illumination prompted this investigation and study of the effect of quality of surface and color of wall coverings upon the absorption of light. The ultimate object of the investigation was to deduce a table of luminosity factors from the data thus obtained which will show the illuminating constants of the various colors With respect to white as a standard SQ that it Will be a commercial benefit to Illuminating Engineers and of general interest to the trades.

Paperback. Zustand: New. Print on Demand. This book is an investigation of different wall coverings' impact on the absorption of light. The author's goal was to create a table of luminous factors to assist illuminating engineers in determining a surface's illumination constants. Various surfaces are tested, including wallpaper, burlap, canvas, and paint. The experiments use standard light sources, a diffusing plate, and a Weber photometer to minimize errors. The study reveals that the surface's quality and color significantly affect light absorption. The data and curves show that lighter colors have a high reflecting power due to the white light reflection from the fibers. In contrast, darker colors have a lower reflecting power as the tone of color becomes darker. The book also examines how roughness and smoothness of the surface affect its reflecting power. The author emphasizes that the findings have significant implications for economic illumination in various settings. By understanding the relationship between surface properties and light absorption, professionals can effectively plan lighting systems to achieve optimal illumination levels.
