Abstract
THE Science Museum is holding a Special Exhibition of Electric Illumination, which will remain open until April 25, 1937. Push-button demonstrations illustrate the principles involved in illuminating engineering practice, such as various types of reflection and transmission of light, reflection factors, effects of contrast, etc. Two full-sized rooms are devoted to decorative lighting and standard lighting system definitions. The great advances made in tungsten filament lamps are illustrated by exhibits showing the control now exercised during manufacture. The electric discharge lamp is dealt with in detail. Apart from examples of discharge lamps and their application to street lighting, industrial lighting and floodlighting, there are exhibits illustrating the cyclical form of the discharge and stroboscopic applications. All types from low-pressure tubes to water-cooled quartz tubes operating at 8,000 ° C. are shown. The phenomenon of luminescence, discovered by Crookes in 1879 and now applied to discharge lamps, is shown in considerable detail. By way of contrast, a concise historical exhibit illustrates the state of illumination technique through the ages. The exhibition has been arranged by Mr. W. T. O'Dea, of the Science Museum, with the assistance of the E.L.M.A. Lighting Service Bureau and an advisory committee under the chairmanship of Mr. C. Rodgers.
