Abstract

The natural phenomenon which we know as light governs to a large extent all our activities; it is therefore not surprising that ever since the earliest times man has endeavoured to produce artificial light. Sources of such light have in the course of time been evolved, from the primitive wood-fire by way of oil lamps, candles, paraffin and gas lamps in numerous varieties, to the present-day electrical sources of light, the electric filament and gas discharge lamps.
