It started when man learned tocontrol fire, and for thousands of years afterwards the simple flameremained the only source of artificial light available. Subsequent attempts torefine the process of light generation and separate it from heat productioncan be roughly divided into four stages:Four important stages in the development of light sourcesStage 1 was marked by the wish to produce a constant flame, which couldbe left relatively unattended for a longer period. This resulted, still in thestone age, in the first bowl-type lamps, burning animal or vegetable oil andfitted with a wick, and later - probably in Roman times - to the invention ofthe candle. The lamp and the candle, like the torch, made light ‘portable’.The next big stride in the development of light sources took place just twocenturies ago, when the first successful steps were taken to increase thelight output of the flame. The physicist Ami Argand it was who gave hisname to the tubular burner, which launched the era of lighting technology.The third stage began a little over a century ago, when the flame as a lightsource was abandoned in favour of an incandescent solid body. Theincandescent electric lamp and the gas mantle were the two importantinventions during this period of development.Finally, in the second decade of the present century, it became possible toproduce light without wasting energy on its traditional byproduct - heat, fordischarge lamps in various forms went into commercial production.Development of these lamps is still in full swing today.Parallel to the development of light sources, came the increase in ourknowledge of the nature and behaviour of light. Commonplace though itmight have been, the controversy among philosophers and scientists aboutthe exact nature of light raged for centuries, and was not finally settled untilcomparatively recently.Lighting technology Scientific investigation into the proper application of light - LightingTechnology - started comparatively late, as was the case with most multi-disciplinary sciences. National lighting societies sprang up in Europe and theUnited States in the first decade of the present century. Their activities wereput on an international footing by the foundation of the ‘Commissionlnternationale de l’Eclairage’ (CIE) or ‘International Lighting Commission’, inwhich experts from all parts of the world and from all provinces of science,technology and design contribute to the expansion of our knowledgesurrounding lighting and lighting application.1. The role of lighting in modern societyIt is difficult to overestimate the importance of artificial light in our present-day society. Without it, commercial, social and cultural life would come to avirtual stand-still with the onset of darkness. And yet task lighting - designedto allow work to continue after dark, rather than facilitating basic orientation -like so many other achievements is a by-product of the Industrial Revolution.3Fig. 1 A simple oil-flame - in addition to the light from the open fire - was theonly source of light available in an average household before the nineteenthcentury. The man entering from outside carries a portable lightThe influence of the Industrial RevolutionThis started at the beginning of the eighteenth century, and would in a fewhundred years change the face of the earth as never before in the history ofmankind. It was more than just a technical revolution, it was an economicaland social one too, that brought with it industrial mass production andmechanized transport.It also meant the end of a way of life that was dictated by the daily passageof the sun and the change of seasons, a way of life that had changed verylittle over thousands of years. Daylight and weather still continued to governagricultural activity, and with it the associated crafts and trades. Although oillamps and candles existed, the costs of the fuel they burned was so high asto make it uneconomical to continue most types of economic activity afterdarkness, and for the poorer classes of the population - the great majority -the open domestic fire remained the only source of light (Fig. 1).More and cheaper light All this changed dramatically with the advent of planned production and theorganised long-distance transport of people and goods. Contemporarylighting was both inadequate and expensive, and so seriously hamperedexpansion of these activities. Consequently inventors were pressed to turnto alternative light sources, and at the same time reduce the costs of fuel.The success of their efforts is clearly demonstrated by the followingexample. Compared with the most advanced light source currently availablefor domestic use, the SL* lamp, candles producing the same amount of lightwould be approximately 2000 times more expensive in terms of energyconsumption, a staggering figure indeed!We are reminded of the almost mystical role that artificial light played in thepast by the fact that in many cultures the lamp is still seen as a symbol,associated with truth, inspiration, progress, hope and wealth (Alladin!).Indeed, it is safe to state that our present-day society would beunrecognizable without artificial lighting.42.History of light sources2.1Before the advent of the lampThe harnessing of fire Artificial light entered into the history of mankind with the harnessing of fire.This, along with the introduction of the first primitive tools, must have beenone of man’s earliest achievements. Needless to say, in those early daysfire was certainly not primarily used as a light source, but rather for itswarmth, as a protection against animals, and to prepare food. And yet itcould not have been long before the first portable light source was‘invented’, in the form of primitive torches made from the branches ofresiniferous trees.2.2The oldest lamps2.2.1Primitive oil lampsOil lamps were used all over the worldThe oldest known artifacts made especially for lighting purposes date from atleast 20 000 years ago. They take the form of primitive oil lamps; made of ahollowed-out stone (Fig. 2 left). The same basic design of lamp has beenused all over the world, remaining principally unchanged until well into theeighteenth century. It consisted basically of a fuel reservoir and a wick,sometimes completed by a pedestal or suspension device and a collector forspilled oil.Vegetable or animal oil or fat was burned in these lamps. During the latercenturies in Europe either olive or colza oil was generally used, as it burnedwith a steady, smoke-free flame. The wick would be made of bark, moss orplant fibres, and was either free-floating, supported by a spike, or laid in asloping groove or lip in the rim of the reservoir (Fig. 2 centre). With latertypes of oil lamp the wick was usually led through a spout (Fig. 2 right).2.2.2CandIes and torchesToday’s candles differ considerably from those before 1800Compared with the oil lamp the candle is relatively recent, and is said tohave been invented by the Romans soon after the birth of Christ. The firstcandles were made either of hard animal fat (tallow) or beeswax. The latterwere of superior quality, but also far more expensive.Fig. 2 Oil-lamps, made of a hollowed-out stone (left), of earthenware in theform of a shell (centre), and of brass with a spout (right).5Fig. 3 A bog-deal torch foruse indoors.At the end of the eighteenth century an urgent need arose for a candlematerial of better quality than tallow, but less costly than beeswax. Fromabout 1830 on, stearine became popular, a product obtained by chemicaltreatment of animal or vegetable fat or oil. Finally, in the second half of thenineteenth century, paraffin became available for candle-making. This is adistillation product of mineral oil or pitch, but can also be obtained from theresidues of coal-gas production. These new materials, together with thebraided cotton wick, which was introduced around 1800, resulted in thedomestic candle as we know it today.‘Poor-man’s’ versions of the candle - mainly used in Northern Europe - werethe rushlight, a piece of stripped rush dipped in molten tallow, and the bog-deal torch, a splinter of long-burning pine wood found in peat bogs (Fig. 3).Outdoor lighting usually took the form of torches or flambeaux, which weresticks topped off with rope or tow and dipped in resin, fat or pitch. They wereused to illuminate outdoor festivities, and were carried by runners to light theway for the carriages and sedan chairs of the rich.2.2.3Further development of the oil lampThe economic and social pressure for more, better and cheaper lighting,brought about by the Industrial Revolution, led, from about 1780 on, to aflood of inventions, aimed either at improving existing light sources(especially the oil lamp) or at the development of completely new methods oflight production - for example gas lighting, and later on electric lighting.The tubular oil burner A first step toward improving the light output of the oil flame was made in1784, when the Swiss physicist Ami Argand invented a round burner with atubular wick, which was named after him (Fig. 4). As air is drawn up insidethe wick, combustion is improved, resulting in an increase in light output fromthe flame and less risk of smoke. The upward air draught was considerablyincreased by the subsequent invention, by Argand’s partner Quinquet, of theglass chimney.Vegetable oil was used exclusively in these improved lamps. As this issomewhat sticky by nature, much thought was given to finding methods toensure a constant supply to the burner without overflowing. From 1836 on,the ‘Moderator lamp was introduced. This was fitted with a spring-loadedpiston to pressure-feed the burner (Fig. 5).6Fig. 4 A typical Argand burner, fitted with a Fig. 5 A ‘Moderator’ lamp for colza oil, withflame spreader.pressure-feed to the burner.Mineral oil replaces vegetable oilBecause of the relatively high price of vegetable oil and its tendency to clog theburner, making frequent cleaning necessary, a fuel that could be used as asubstitute was eagerly sought after. In 1847 the Scotsman James Youngdiscovered a refining process for mineral oil, and thus produced the first paraffinoil. It proved to be an ideal fuel for oil lamps, rapidly replacing vegetable oil after itbecame cheaply available around 1860.In less than a century the oil lamp had evolved from a rather primitive lightsource into one that was highly effective. The largest single-f lame types, asused in churches, schools and public rooms, had a light output of some 2500lumens. Furthermore, availability of cheap fuel helped its proliferation at all levelsof Victorian society, and even the most modest of house-holds had at least adozen lamps at their disposal.Apart from differences in size and decoration, a host of specially adapted lampscame about, for portable, industrial and marine use, as well as for street andvehicle lighting. Perhaps the most famous among these special versions is theminer’s safety lamp, invented in 1813 almost simultaneously by GeorgeStephenson and Sir Humphry Davy. It is still used today in coal mines, althoughno longer for general lighting purposes (Fig. 6).Oil lamps for street lightingStreet lighting on any scale was unheard of before the middle of the seventeenthcentury -people going out after dark carried their own lights. The invention of anoil lantern specially suited to street lighting is usually attributed to the DutchmanJan van der Heyden, who first used it to light the streets of his home townAmsterdam in 1669. The all-enclosed lantern housed a shouted oil lamp, fittedwith a special reservoir that maintained a constant oil level on the wick (Fig. 7).In the following fifty years most of the major cities of the old world received streetlighting, be it on a very limited scale by present-day standards. From 1810 on,gas lighting quickly gained ground in towns, it being both cheaper on fuel andmaintenance, but in rural areas the oil lantern lasted well into the presentcentury.By 1870, development of the oil lamp had almost come to an end. The onlysignificant improvement made after that date was in around 1895 when Auer vonWelsbach’s gas mantle (q.v.) was adapted for use with oil lamps. In some casesthe oil reservoir was also pressurised to improve combustion (Fig. 8).7Fig. 6 A ‘Davy’ miner’s safety Fig. 7 Oil-burning street lantern Fig. 8 Modern pressurizedlamp with a flat wick for of the type introduced in paraffin oil-lamp, fitted with anparaffin oil.Amsterdam in 1669 by Jan van incandescent mantle.der Heyden.2.3Gaslight2.3.1Early historyThe existence of flammable gas was known for ages, but it was not until theeighteenth century that man attempted to use it to his benefit. The earliestexperiments using gas for lighting purposes were carried out by threescientists, independently of each other. They were the Dutchman JanMinckelers, who in 1783 produced coal gas to light his lecture room at theuniversity of Louvain, the Englishman George Dixon, and the FrenchmanPhilippe Lebon.The first to exploit coal gas commercially must have been William Murdock, aScot. In 1803 he successfully lighted the Soho works of the Boulton and WattCompany, where he was employed. The following year he sold a lightinginstallation with fifty lights to a cotton spinning mill in Salford, nearManchester. Over the following years the capacity was extended to cover thewhole premises, the owner claiming that, compared with tallow candles,annual lighting costs had dropped to a fifth.Gas was first used for street lightingThe idea of centralising gas production and distributing it over the townthrough a network of pipes came from a German working in London, oneFriedrich Albert Winzer, or Winsor as he called himself in England. He wasneither an engineer, nor a scientist, but a businessman of considerableenterprise who was able to interest political and financial circles in his plan.In 1807, after a successful demonstration in London, he formed the NationalLight and Heat Company which, after being renamed to the Gas Light andCoke Company in 1812, would grow to be the largest gas company in theworld. Yet, in those early days, gas lighting was far from ideal. Supply waserratic and the pressure in the mains would drop to almost zero during peakloads. The smell of the insufficiently purified gas restricted its use indoors,and the price was still high. Nevertheless, because of the low maintenancecosts of the lamps, it was strongly favoured for street lighting. Heavycompetition - in 1823 there were in London alone already three rival gascompanies meant that the quality of the gas and the reliability of its supplyquickly improved, while the price dropped steeply during the same period.82.3.2Gas productionCoal gas is produced by heating bituminous coal in cast-iron retorts, in theabsence of air. The methane liberated during this process is cleaned ofundesirable admixtures before being stored in the gasometer, today still awell-known landmark in many towns. From there it is pressure-fed into themains, either by pumping or by the weight of the movable upper part of thegasometer. What is left in the retorts is highly carboniferous coal, calledcokes, which is used for the production of iron from its ore in blast furnaces,or for heating purposes.2.3.3Gaslight burnersFlat-flame and Argand burnersThe first gaslight burners were nothing more than narrow apertures at Theends of pipes. The number and configuration of the openings gave theflame(s) a specific shape, and thus names like ‘rat-tail’, ‘cockspur’ and‘cockscomb’ burner evolved.As with oil lamps, attemps were made to increase the light output of the gasflame. This resulted in the introduction of flat-flame burners, named ‘bats-wing’ or ‘fish-tail’ burners after the shape of the flame. In 1809, SamuelClegg managed to adapt the Argand burner for use with gas, which - fittedwith a glass chimney - would remain the most popular type until theintroduction of the gas mantle (Fig. 9). A further improvement, aimed atincreasing the efficiency of the lamp, was introduced in 1886, whereby theincoming air needed for combustion was preheated by the flue gases. Thisresulted in the so-called regenerative lamp (Fig. 10).2.3.4 The gas-mantleA dramatic step foreward was made in 1887. Following numerous attemptsby a host of inventors - even including Thomas Alva Edison - over a periodof twenty-five years, to improve the luminosity of the gas flame by bringingsolid material in it to incandescence, it was at last the Austrian physicist CarlAuer von Welsbach who met with success.The story of the origin of the incandescent gas lamp is not unlike that of theelectric incandescent lamp, invented some ten years earlier. It was not somuch a problem to find a material that could be brought to brilliantincandescence, but rather to find one that would last long enough to becomepracticable. MostCarl Auer von Welsbach experimenters tried platinum gauze, coated with various oxides, ormagnesia, but these materials were prone to prematureFig. 9 Gas chandelier, fittedwith two Argand burners.9Fig. 10 Regenerative gas-lamp Fig. 11 Early upright ‘Auer’ gas-Fig. 12 Acetylene lantern forfor use in factories, fitted with e on bicycles.an inverted incandescentmantle.disintegration.Auer von Welsbach used a tube of fabric, impregnated with amixture of thorium and cerium salts. The fabric would burn away leaving abrittle, but heat-resistant structure consisting of the oxides of the afore-mentioned metals - the so-called gas-mantle (Fig. 11). Its brilliant light isattributable to the phenomenon of candoluminescence -fluorescencestimulated by heat.The battle of gas versus electricityThe gas-mantle lamp came in the nick of time to provide the mighty gascompanies with an adequate answer to the electric incandescent lamp. Andso successful was it that the proliferation of electric lighting was seriously setback by it for many years. In many parts of the world it was only after the1940-1945 war that electricity took a definite lead in lighting.Over the years the gas-mantle lamp underwent a number of improvements,the most important being the introduction of the inverted burner, in 1897.This had two advantages over the upright one: the downward light was nolonger intercepted by the burner, and the heat of the flame stayed inside themantle, thus increasing the efficiency of the burner.Acetylene gas for lighting Gas was also used for lighting vehicles, ranging from bicycles to railwaycarriages. This was accomplished using acetylene gas, which was producedby adding water to calcium carbide dropwise in a special reservoir (Fig. 12).Owners of isolated houses and mansions could buy their own ‘gasworks’based upon the same principle for lighting the premises. Nowadays,propane gas in pressurized containers is sometimes used to the same end.An almost forgotten form of gas lighting, except in the metaphorical sense, isthe ‘limelight’, reputedly invented by Drummond in 1804. By heating acylinder of quicklime to incandescence in an oxyhydrogen flame, a compact,extremely intense light source was obtained, which was used for projectionor theatre lighting.Although in the home since long superseded by electricity, gas is stillextensively used for street lighting in some countries. The city of West-Berlin, for example, still uses some 40 000 gas lanterns, mostly of a moderndesign (Fig. 13).10。
