Willst du wissen, wie sich die Beleuchtung entwickelt hat? Oder haben Sie sich schon einmal gefragt, wie die Menschen vor hundert Jahren in der Dunkelheit geleuchtet haben? Der Mangel an nat\u00fcrlichem Licht in der Nacht in st\u00e4dtischen Gebieten war schon immer ein Problem. In dunklen N\u00e4chten kann es f\u00fcr die Menschen schwierig sein, sich fortzubewegen. Und ohne \u00f6ffentliche Beleuchtung war die Wahrscheinlichkeit gr\u00f6\u00dfer, dass Menschen nachts \u00fcberfallen oder ausgeraubt wurden. Wir werden uns nun die historische Entwicklung der \u00f6ffentlichen Beleuchtung ansehen.<\/div>\n<div data-zone-id=\"0\" data-line-index=\"1\">\n<div>Die fr\u00fchesten Formen der \u00f6ffentlichen Beleuchtung waren Pflanzen\u00f6le oder Kerzen zur Erhellung. Im alten Rom benutzten wohlhabende B\u00fcrger Pflanzen\u00f6llampen, um Licht zu haben. Chinesische B\u00fcrger z\u00fcndeten Kerzen an, um Licht zu spenden. Kaum zu glauben ist jedoch, dass die erste bekannte Version einer Stra\u00dfenlampe um 140 v. Chr. auftauchte! Die Griechen und R\u00f6mer beleuchteten die Wege und Stra\u00dfen vor ihren H\u00e4usern, um Diebe abzuschrecken und die Sicht und Sicherheit zu verbessern. Die wohlhabenderen Einwohner stellten Laternensklaven ein, die daf\u00fcr sorgten, dass die Stra\u00dfenlaternen die ganze Nacht \u00fcber hell und sauber blieben. Allerdings handelte es sich dabei nur um eine private und nicht um eine \u00f6ffentliche Beleuchtung, bis der B\u00fcrgermeister von London 1417 anordnete, dass alle Haushalte ihre Laternen nach Einbruch der Dunkelheit im Winter drau\u00dfen aufh\u00e4ngen sollten. Dies war die erste organisierte \u00f6ffentliche Beleuchtung.<\/div>\n<\/div>\n<div class=\"row\"  id=\"row-1645310143\">\n\n\t<div id=\"col-417654732\" class=\"col medium-6 small-12 large-6\"  >\n\t\t\t\t<div class=\"col-inner\"  >\n\t\t\t\n\t\t\t\n\t<div class=\"img has-hover x md-x lg-x y md-y lg-y\" id=\"image_1707041327\">\n\t\t\t\t\t\t\t\t<div class=\"img-inner dark\" >\n\t\t\t<img decoding=\"async\" width=\"400\" height=\"400\" src=\"https:\/\/kanglight.com\/wp-content\/uploads\/2020\/05\/South-America.jpg\" class=\"attachment-large size-large\" alt=\"LED-STRASSENLAMPE\" srcset=\"https:\/\/kanglight.com\/wp-content\/uploads\/2020\/05\/South-America.jpg 400w, https:\/\/kanglight.com\/wp-content\/uploads\/2020\/05\/South-America-100x100.jpg 100w, https:\/\/kanglight.com\/wp-content\/uploads\/2020\/05\/South-America-300x300.jpg 300w, https:\/\/kanglight.com\/wp-content\/uploads\/2020\/05\/South-America-80x80.jpg 80w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/>\t\t\t\t\t\t\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\n<style>\n#image_1707041327 {\n  width: 100%;\n}\n<\/style>\n\t<\/div>\n\t\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t\n\n\t<div id=\"col-37100097\" class=\"col medium-6 small-12 large-6\"  >\n\t\t\t\t<div class=\"col-inner\"  >\n\t\t\t\n\t\t\t\n\t<div class=\"img has-hover x md-x lg-x y md-y lg-y\" id=\"image_1806199793\">\n\t\t\t\t\t\t\t\t<div class=\"img-inner dark\" >\n\t\t\t<img decoding=\"async\" width=\"700\" height=\"700\" src=\"https:\/\/kanglight.com\/wp-content\/uploads\/2021\/05\/TOPAZ.png\" class=\"attachment-large size-large\" alt=\"STRASSENLICHT\" srcset=\"https:\/\/kanglight.com\/wp-content\/uploads\/2021\/05\/TOPAZ.png 700w, https:\/\/kanglight.com\/wp-content\/uploads\/2021\/05\/TOPAZ-300x300.png 300w, https:\/\/kanglight.com\/wp-content\/uploads\/2021\/05\/TOPAZ-80x80.png 80w, https:\/\/kanglight.com\/wp-content\/uploads\/2021\/05\/TOPAZ-100x100.png 100w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/>\t\t\t\t\t\t\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\n<style>\n#image_1806199793 {\n  width: 100%;\n}\n<\/style>\n\t<\/div>\n\t\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t\n<\/div>\n<h2 class=\"okr-block-clipboard\" data-okr=\"%7B%22okrDelta%22%3A%5B%7B%22lineType%22%3A%22text%22%2C%22lineOptions%22%3A%7B%7D%2C%22lineContent%22%3A%5B%7B%22opType%22%3A%22text%22%2C%22options%22%3A%7B%22text%22%3A%22The%20Eighteen%20Fifties%22%7D%7D%5D%7D%2C%7B%22lineType%22%3A%22text%22%2C%22lineOptions%22%3A%7B%7D%2C%22lineContent%22%3A%5B%7B%22opType%22%3A%22text%22%2C%22options%22%3A%7B%22text%22%3A%22The%20great%20inventor%20Benjamin%20Franklin%20first%20introduced%20street%20lighting%20in%20the%20United%20States.%20Franklin%20carried%20out%20several%20experiments%20with%20electricity%20and%20invented%20the%20lightning%20rod.%20He%20then%20proposed%20that%20pawn%20oil%20candles%20be%20encased%20in%20glass%20with%20a%20long%20funnel%20for%20smoking%20and%20a%20slit%20underneath%20to%20allow%20air%20to%20enter.%20In%20this%20way%2C%20the%20candle%20would%20be%20lit%20inside%20the%20glass%20container%20and%20difficult%20to%20blow%20out%20even%20in%20the%20wind.%20This%20is%20the%20earliest%20prototype%20of%20the%20city%20street%20lights%20-%20the%20oil%20and%20wax%20lamp.%20Because%20Franklin%20was%20the%20postmaster%20of%20Philadelphia%2C%20many%20people%20regard%20Philadelphia%20as%20the%20birthplace%20of%20street%20lighting%20in%20the%20United%20States.%20Many%20places%20still%20chose%20to%20use%20oil%20wax%20lamps%20until%20the%20nineteenth%20century%20when%20methane%20gas%20was%20used%20for%20lighting%20in%20the%20United%20States.%22%7D%7D%5D%7D%5D%2C%22businessKey%22%3A%22lark-doc%22%7D\">Die achtzehn f\u00fcnfziger Jahre<\/h2>\n<div data-zone-id=\"0\" data-line-index=\"1\">Der gro\u00dfe Erfinder Benjamin Franklin f\u00fchrte in den Vereinigten Staaten erstmals eine \u00f6ffentliche Stra\u00dfenbeleuchtung ein. Franklin f\u00fchrte mehrere Experimente mit Elektrizit\u00e4t durch und erfand den Blitzableiter. Dann schlug er vor, \u00d6lkerzen mit einem Glas zu umh\u00fcllen, das einen langen Trichter f\u00fcr das R\u00e4uchern und einen Schlitz an der Unterseite hatte, durch den Luft eindringen konnte. Auf diese Weise w\u00fcrde die Kerze im Inneren des Glasbeh\u00e4lters brennen und k\u00f6nnte auch bei Wind nicht ausgeblasen werden. Dies ist der fr\u00fcheste Prototyp der st\u00e4dtischen Stra\u00dfenbeleuchtung - die \u00d6l- und Wachslampe. Da Franklin Postmeister in Philadelphia war, gilt Philadelphia vielen als Geburtsort der Stra\u00dfenbeleuchtung in den Vereinigten Staaten. Vielerorts wurden noch \u00d6l-Wachs-Lampen verwendet, bis im 19. Jahrhundert Methangas f\u00fcr die \u00f6ffentliche Beleuchtung in den Vereinigten Staaten eingesetzt wurde.<\/div>\n<h2 data-okr=\"%7B%22okrDelta%22%3A%5B%7B%22lineType%22%3A%22text%22%2C%22lineOptions%22%3A%7B%7D%2C%22lineContent%22%3A%5B%7B%22opType%22%3A%22text%22%2C%22options%22%3A%7B%22text%22%3A%22Nineteenth-century%22%7D%7D%5D%7D%2C%7B%22lineType%22%3A%22text%22%2C%22lineOptions%22%3A%7B%7D%2C%22lineContent%22%3A%5B%7B%22opType%22%3A%22text%22%2C%22options%22%3A%7B%22text%22%3A%22By%20the%2019th%20century%2C%20methane%20gas%20was%20available%2C%20and%20the%20use%20for%20lighting%20increased.%201802%20saw%20the%20invention%20of%20the%20gas%20lamp%20by%20Scottish%20inventor%20William%20Murdoch%2C%20an%20invention%20that%20illuminated%20the%20exterior%20of%20the%20SoHo%20foundry.%201807%20saw%20the%20first%20gas%20street%20in%20London.%20In%201816%2C%20Baltimore%20became%20the%20first%20city%20in%20the%20United%20States%20to%20install%20gas%20streetlights.%20Paris%20followed%20in%201820.%20At%20this%20time%2C%20%20install%20gas%20through%20pipes%20to%20gas%20lamps%20placed%20on%20utility%20poles.%20Each%20night%20a%20special%20crew%20lit%20the%20lanterns%2C%20and%20each%20morning%2C%20they%20turned%20the%20lights%20off%20again.%20This%20continued%20until%20the%20invention%20of%20lighting%20the%20lamps%20when%20releasing%20the%20gas%20in%20them.%22%7D%7D%5D%7D%2C%7B%22lineType%22%3A%22text%22%2C%22lineOptions%22%3A%7B%7D%2C%22lineContent%22%3A%5B%7B%22opType%22%3A%22text%22%2C%22options%22%3A%7B%22text%22%3A%22It%20was%20not%20until%20Thomas%20Edison%20created%20a%20pure%20vacuum%20in%20the%20light%20bulb%20that%20he%20changed%20the%20future%20of%20public%20lighting%20for%20the%20world.%20Edison's%20carbon%20filament%20incandescent%20lamp%20was%20introduced%20in%201879%20and%20gave%20impetus%20to%20the%20development%20of%20public%20lighting.%20This%20gave%20a%20major%20impetus%20to%20the%20subsequent%20development%20of%20public%20street%20lighting.%20The%20first%20city%20in%20the%20USA%20to%20successfully%20demonstrate%20electric%20lighting%20was%20Cleveland%2C%20Ohio%2C%20with%2012%20electric%20lights%20around%20the%20public%20square%20road%20system%20on%2029%20April%201879.%22%7D%7D%5D%7D%2C%7B%22lineType%22%3A%22text%22%2C%22lineOptions%22%3A%7B%7D%2C%22lineContent%22%3A%5B%7B%22opType%22%3A%22text%22%2C%22options%22%3A%7B%22text%22%3A%22By%20the%201880s%2C%20Indiana%20was%20the%20first%20town%20in%20the%20United%20States%20to%20introduce%20electric%20street%20lighting.%20This%20is%20how%20public%20lighting%20first%20began%2C%20with%20the%20installation%20of%20arc%20lamps%2C%20also%20known%20as%20Yablochkov%20candles%2C%20in%20Paris%20in%201878.%20Three%20years%20later%2C%204%2C000%20of%20these%20electric%20lamps%20were%20in%20use%2C%20effectively%20replacing%20the%20gas%20lamps%20mounted%20on%20utility%20poles.%20But%20the%20disadvantage%20of%20the%20arc%20lamps%20was%20that%20they%20emitted%20a%20strong%2C%20blinding%20light%20and%20did%20not%20last%20long.%20In%20time%2C%20therefore%2C%20they%20were%20replaced%20by%20cheaper%2C%20brighter%2C%20and%20longer-lasting%20incandescent%20lamps.%20But%20to%20this%20day%2C%20arc%20lamps%20are%20still%20useful%20on%20certain%20industrial%20sites.%22%7D%7D%5D%7D%5D%2C%22businessKey%22%3A%22lark-doc%22%7D\">Stra\u00dfenbeleuchtung im neunzehnten Jahrhundert<\/h2>\n<div data-zone-id=\"0\" data-line-index=\"1\">Im 19. Jahrhundert war Methangas verf\u00fcgbar, und die Verwendung f\u00fcr die Beleuchtung nahm zu. 1802 erfand der schottische Erfinder William Murdoch die Gaslampe, eine Erfindung, die die Au\u00dfenbeleuchtung der Gie\u00dferei in SoHo erm\u00f6glichte. 1807 gab es die erste Gasstra\u00dfe in London. 1816 wurde Baltimore die erste Stadt in den Vereinigten Staaten, die Gasstra\u00dfenlampen installierte. Paris folgte im Jahr 1820. Zu dieser Zeit wurde das Gas durch Rohre zu Gaslampen geleitet, die an Versorgungsmasten angebracht waren. Jeden Abend z\u00fcndete eine spezielle Mannschaft die Laternen an, und jeden Morgen schalteten sie die Lichter wieder aus. Dies dauerte bis zur Erfindung der Beleuchtung der Lampen bei der Freigabe des Gases in ihnen.<\/div>\n<div data-zone-id=\"0\" data-line-index=\"2\">Erst als Thomas Edison in der Gl\u00fchbirne ein reines Vakuum schuf, ver\u00e4nderte er die Zukunft der \u00f6ffentlichen Beleuchtung in der Welt. Edisons Kohlefaden-Gl\u00fchlampe wurde 1879 eingef\u00fchrt und gab der Entwicklung der \u00f6ffentlichen Beleuchtung einen Ansto\u00df. Dies war ein wichtiger Ansto\u00df f\u00fcr die sp\u00e4tere Entwicklung der \u00f6ffentlichen Stra\u00dfenbeleuchtung. Die erste Stadt in den USA, die erfolgreich eine elektrische Stra\u00dfenbeleuchtung vorf\u00fchrte, war Cleveland, Ohio, wo am 29. April 1879 12 elektrische Lichter rund um das \u00f6ffentliche Stra\u00dfennetz in Betrieb genommen wurden.<\/div>\n<div data-zone-id=\"0\" data-line-index=\"3\">In den 1880er Jahren war Indiana die erste Stadt in den Vereinigten Staaten, die eine elektrische Stra\u00dfenbeleuchtung einf\u00fchrte. So begann die \u00f6ffentliche Beleuchtung mit der Installation von Bogenlampen, auch bekannt als Jablotschkow-Kerzen, in Paris im Jahr 1878. Drei Jahre sp\u00e4ter waren bereits 4.000 dieser elektrischen Stra\u00dfenlaternen in Betrieb und ersetzten die Gaslampen an den Strommasten. Die Bogenlampen hatten jedoch den Nachteil, dass sie ein starkes, blendendes Licht ausstrahlten und nicht lange hielten. Mit der Zeit wurden sie daher durch billigere, hellere und langlebigere Gl\u00fchlampen ersetzt. Aber auch heute noch sind Bogenlampen an bestimmten Industriestandorten n\u00fctzlich.<\/div>\n<div class=\"row\"  id=\"row-1176797677\">\n\n\t<div id=\"col-1863989010\" class=\"col medium-6 small-12

Jahrhundert<\/h2>\n<div data-zone-id=\"0\" data-line-index=\"1\">Zu Beginn des 20. Jahrhunderts waren die urspr\u00fcnglichen Gas- oder Methanlampen daf\u00fcr bekannt, dass sie Br\u00e4nde verursachten. Die Hersteller von Stra\u00dfenlaternen suchten daher nach einer sichereren und effizienteren Methode, die Stra\u00dfen zu beleuchten. Erst in den 1930er und 1940er Jahren setzten sich Leuchtstoff- und Gl\u00fchlampen durch. Zu dieser Zeit begann auch der Autoverkehr zu florieren. 1930 wurden Niederdruck-Natriumdampflampen popul\u00e4r, die eine abnehmbare \u00e4u\u00dfere Umh\u00fcllung und eine Vakuumschicht zur Isolierung besa\u00dfen. Auf diese Weise konnte das Natrium bei hohen Temperaturen in Dampfform gehalten werden. Zu Beginn des 20. Jahrhunderts wurden die beleuchteten Stra\u00dfen als wei\u00dfe Stra\u00dfen bezeichnet. Erst 1962 wurden die ersten praktischen Leuchtdioden (LEDs) mit sichtbarem Spektrum entwickelt, und 1965 brachten Natriumdampf-Hochdrucklampen (HID) eine bessere Farbe und Effizienz als ihre Niederdruck-Pendants. Zu diesem Zeitpunkt nahm die \u00f6ffentliche Beleuchtung bereits Gestalt an.<\/div>\n<div data-zone-id=\"0\" data-line-index=\"2\">\n<h2>Stra\u00dfenbeleuchtung im einundzwanzigsten Jahrhundert<\/h2>\n<\/div>\n<div data-zone-id=\"0\" data-line-index=\"3\">Die Erfindung der LED-Stra\u00dfenbeleuchtung im einundzwanzigsten Jahrhundert kann als gro\u00dfer Fortschritt f\u00fcr \u00f6ffentliche LED-Leuchten angesehen werden. Von diesem Zeitpunkt an wurde die LED-Stra\u00dfenbeleuchtung allt\u00e4glich, und die LED-Energiespartechnologie florierte. Die Einf\u00fchrung von LED-Stra\u00dfenbeleuchtung bietet auch eine bessere Kontrolle und Vielseitigkeit. LED-Stra\u00dfenleuchten sind kosteng\u00fcnstig und wartungsarm und erm\u00f6glichen es den Kunden, Farbtemperatur, Wattzahl usw. f\u00fcr jede Anwendung zu bestimmen. Fr\u00fcher waren LED-Stra\u00dfenlaternen teuer, obwohl immer wieder davon die Rede war, mehr gr\u00fcne Energie zu nutzen und den CO2-Fu\u00dfabdruck zu verringern. Viele St\u00e4dte haben sich f\u00fcr LED-Beleuchtung entschieden, um Geld zu sparen und gleichzeitig die Umwelt zu sch\u00fctzen. Die LED-Beleuchtung im \u00f6ffentlichen Raum nimmt daher rasch zu und wird in gro\u00dfem Umfang eingesetzt. J\u00fcngste Studien in Los Angeles haben gezeigt, dass die Kriminalit\u00e4tsrate nach der Installation von LED-Beleuchtung zur\u00fcckgegangen ist. Die beleuchtete Fl\u00e4che ist gr\u00f6\u00dfer als bei herk\u00f6mmlichen Stra\u00dfenlaternen. Dadurch f\u00fchlen sich die Menschen sicherer, wenn sie sp\u00e4tabends nach Hause gehen.<\/div>\n<h2>Schlussfolgerung<\/h2>\n<p>So hat sich die \u00f6ffentliche Stra\u00dfenbeleuchtung in den letzten dreihundert Jahren entwickelt. Und jetzt werden intelligente Leuchten wieder popul\u00e4r. Intelligente Leuchten erkennen Fu\u00dfg\u00e4nger und Fahrzeuge bei Dunkelheit und schalten sich dann automatisch ein und aus. Diese intelligenten Leuchten sind sogar noch energieeffizienter als LED-Stra\u00dfenlampen. Mit der Entwicklung der heutigen Technologie werden sich intelligente Leuchten meiner Meinung nach immer schneller durchsetzen. Das liegt daran, dass sie ein Zeichen f\u00fcr den kontinuierlichen Fortschritt der Menschen sind.<\/p>\n<p>Und auch die \u00f6ffentliche Beleuchtung wird in Zukunft ein st\u00e4ndiges Thema sein. Nicht nur, dass die alte \u00f6ffentliche Beleuchtung veraltet ist, weil sie sehr viel Energie verbraucht. Sondern auch, weil sie nicht intelligent ist und vielerorts zu wei\u00dfer Verschmutzung f\u00fchrt. Viele Arten der \u00f6ffentlichen Beleuchtung k\u00f6nnen ebenfalls Probleme verursachen.<\/p>","protected":false},"excerpt":{"rendered":"<p>Heutzutage geht die \u00f6ffentliche Beleuchtung in jeder dunklen Nacht p\u00fcnktlich an, was einen technischen Fortschritt darstellt.
