Introduction to Industrial Hygiene Engineering and Control (552), Module 5 - Instructor's Manual, Industrial Illumination.
The material contained in this instructor's manual was intended for use at the college level by students at an advanced level of industrial hygiene study; this module covered industrial illumination. The first lesson considered the physics of light, how light is emitted and the various sources of light. The second section discussed how light behaves after it leaves the source, the factors involved in seeing and general principles of lighting design. The third section discussed the lumen method of calculation. In the section on designing a lighting system, the manual covered quality of light; quality of light including such topics as glare, veiling reflections, brightness ratios, diffusion of light, and color; types of luminaries including indirect lighting, semi direct lighting, general diffuse or direct indirect lighting, and direct lighting. Illumination methods were also considered, including general lighting, localized general lighting, and supplementary lighting. Other factors to consider when selecting a lighting system were discussed such as choice of a light source, heat produced from the source, proper candle power distribution, efficiency of the lamp or light source, electrical features, the mechanical structure needed to support the fixture, appearance, color of lights and maintenance.
