Book Description
Excerpt from Electric Lamps IN the following pages I have made no attempt to describe any electric lamps other than those which have been proved to be of commercial use: enough may be written about these to fill a book; an adequate account of those which either have not advanced beyond the laboratory stage or only exist in the fond imagination of their inventors would require at least another volume. With most of the lamps which have reached the com mercial stage I can claim more than a bowing acquaintance as I have been engaged during the last eight years in their manufacture, in the making first of. Nernst filaments, later of carbon filaments, and finally in the manufacture of arc lamp carbons, with a brief digression into experimental work on metallic filaments. Most of the information given in this book has therefore been obtained first hand, and I would like to express my thanks to the directors of the General Electric Company and of Robertson Electric Lamps, Ltd., for their kind permission to publish information obtained in their service.

Book Description
Excerpt from Standard Lighting: With Incandescent Electric Lamps Since an Object is seen by the light which comes to it from the source and thence by reflection to the eye, it follows that color in the Object is seen only when the light contains rays Of that color. For example, a red Object will appear black under light in which red rays are lacking or a blue Object will appear black when blue rays are absent in the source. Daylight is composed of all the colors in proportions seen in the rainbow The light from Mazda lamps contains all the colors composing daylight but if the spectra, or rainbows, Of the two were to be compared it would be seen that the Mazda lamp was richer than daylight in the orange - red region and weaker in the blue. For ordinary purposes, the light from clear Mazda lamps is sufficiently like daylight to answer all requirements, but where color discr1m1nat10n is a factor, as in sorting or grading pro cesses for example, and in the laundry where scorch marks must be readily distinguishable, or where the artificial light is used to supplement daylight, as in an Office, daylight lamps, which screen out the majority Of the excess orange-red rays, find wide application.

Incandescent Electric Lamps and Their Application (Classic Reprint)

Book Description
Excerpt from Incandescent Electric Lamps and Their Application Since the advent of the carbon filament incandescent lamp so many wonderful discoveries have been made that the adoption of the electric glow lamp as an illuminant is now almost universal. A little thought will establish the fact, however, that the improvements made have been chiefly in the lamp itself, the introduction of the metal filament being responsible for the increased efficiency that has placed electric lighting practically within reach of all. In comparison with the advances made in filament construction those made in the direction of scientific artificial lighting have been small. The formation of the Illuminating Engineering Society has done much to create an interest in this important subject, while further, the work of Government Commissions and the publication of their reports on school, factory and library lighting has served still more to impress people with the importance of adequate illumination. If good lighting is important in public institutions it is equally if not more important in the home, and the approved methods of disposing of the light units so as to avoid unnecessary glare and produce an adequate illumination, as well as the judicious selection of wall and ceiling coverings, should be fully understood by all users and installers of electric light. The existing literature on the subject is of too scientific and technical a character for other than scientists, and in presenting this treatise the author hopes that the obvious gap may be filled and that the general reader may be assisted in deciding upon the most suitable candle-power and distribution in his own particular case. The author has to thank Messrs. Siemens Bros, for information concerning tantalum and permission to reproduce one of their diagrams; Messrs. The General Electric Co. for information concerning the drawing down of tungsten filaments; Messrs. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Incandescent Electric Lights: With Particular Reference to the Edison Lamps All these attempts had but partially succeeded, to say nothing more, when, in 1879. The new incandescent carbon lamp of Mr. Edison was announced, and many savants, and myself in particular, doubted the exactness of the allegations which came to us from America. The carbonized paper horse-shoe appeared incapable of resisting mechanical shocks, and of supporting incandescence for any length of time. At this epoch Mr. Swan himself said that up to that time he had not been able to obtain any very satisfactory results by an analagous dis position of the incandescent organ.

Book Description
Excerpt from Electric Lighting There are few engineering activities which have advanced more rapidly during the last few years than have the, art and practice Of electric lighting. Illuminants have been steadily improved and refined. New types Of lamps have been developed giving better colors Of light, more efficient light production, cheaper units and a greater range Of sizes. Principles Of illumination have been studied and applied in the better solution Of lighting problems. Indirect lighting, semi or complete, has introduced great possibilities into the handling Of both small and large installations. The economic value Of good lighting is better appreciated. Color is beginning to play an important part in lighting schemes. It is destined to become even more widely utilized.

Book Description
Excerpt from The Electric Lamp Industry While electric lamp manufacture is essentially a scientific industry, the short account in the following pages is not intended as a technical treatise. Certain data has necessarily been introduced to make the description more complete, which leaves parts of the text open to criticism by those engaged in lamp manufacture. In the preface to most books one usually makes a formal acknowledgment of assistance, but in the present case it is doubtful if the work would have been compiled if the writer's colleagues had not offered such generous help. During a period of severe illness and also while in America the author found the value of many friends, and desires to express publicly his appreciation of help from Dr. W. Phillips, who vigorously but kindly blue pencilled the original copy in the interests of future readers; also to Mr. Paul Freedman for his help in connection with the material in the chapter on vapour lamps and to Mr. S. B. Staines for his efforts in collecting the illustrations. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Evolution of the Electric Incandescent Lamp In the following pages an effort has been made to bring together, in a convenient and accessible form, some of these detached fragments which seemed to have present or prospective historical value, and at the same time, as far as practicable, to indicate for the benefit of future investigators the sources from whence they have been derived. It is hoped that each reader will thus be enabled to formulate his own answer to the inquiry as to whom the world is principally indebted for modern incandescent electric lighting.
