La falta de luz natural por la noche en los entornos urbanos siempre ha sido un problema. Las noches oscuras pueden dificultar los desplazamientos. O sin alumbrado p\u00fablico, la gente ten\u00eda m\u00e1s probabilidades de ser atacada o robada por la noche. Veamos ahora la evoluci\u00f3n hist\u00f3rica del alumbrado p\u00fablico.<\/div>\n<div data-zone-id=\"0\" data-line-index=\"1\">\n<div>Las primeras formas de alumbrado p\u00fablico consist\u00edan en aceites vegetales o velas para proporcionar iluminaci\u00f3n. En la antigua Roma, los ciudadanos ricos utilizaban l\u00e1mparas de aceite vegetal para alumbrarse. Los ciudadanos chinos encend\u00edan velas para alumbrarse. \u00a1Pero lo que tambi\u00e9n es dif\u00edcil de creer es que la primera versi\u00f3n conocida de una farola apareci\u00f3 alrededor del a\u00f1o 140 a.C.! Los griegos y los romanos iluminaban los caminos y las carreteras fuera de sus casas para disuadir a los ladrones y mejorar la visibilidad y la seguridad. Los habitantes m\u00e1s ricos contrataban a esclavos faroleros para que se encargaran de mantener las farolas brillantes y limpias durante toda la noche. Sin embargo, se trataba s\u00f3lo de alumbrado privado y no p\u00fablico hasta 1417, cuando el alcalde de Londres orden\u00f3 a todos los hogares que colgaran sus faroles en el exterior al caer la noche en invierno. Fue el primer alumbrado p\u00fablico organizado.<\/div>\n<\/div>\n<div class=\"row\"  id=\"row-750267146\">\n\n\t<div id=\"col-1934188182\" 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_453671570\">\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=\"FAROLAS LED\" 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_453671570 {\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-1450030778\" 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_2123750134\">\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=\"LUZ DE CALLE\" 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_2123750134 {\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\">Los a\u00f1os cincuenta<\/h2>\n<div data-zone-id=\"0\" data-line-index=\"1\">El gran inventor Benjamin Franklin fue el primero en introducir el alumbrado p\u00fablico en las calles de Estados Unidos. Franklin realiz\u00f3 varios experimentos con electricidad e invent\u00f3 el pararrayos. Luego propuso que las velas de aceite de pe\u00f3n se envolvieran en vidrio con un largo embudo para fumar y una rendija debajo para permitir la entrada de aire. De este modo, la vela quedar\u00eda encendida dentro del recipiente de cristal y ser\u00eda dif\u00edcil que se apagara incluso con el viento. Este es el prototipo m\u00e1s antiguo de las farolas urbanas: la l\u00e1mpara de aceite y cera. Como Franklin era el jefe de correos de Filadelfia, mucha gente considera a esta ciudad como la cuna del alumbrado p\u00fablico en Estados Unidos. Muchos lugares siguieron optando por las l\u00e1mparas de aceite y cera hasta el siglo XIX, cuando se empez\u00f3 a utilizar el gas metano para el alumbrado p\u00fablico en Estados Unidos.<\/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\">El alumbrado p\u00fablico en el siglo XIX<\/h2>\n<div data-zone-id=\"0\" data-line-index=\"1\">En el siglo XIX ya se dispon\u00eda de gas metano, y su uso para iluminaci\u00f3n aument\u00f3. En 1802, el inventor escoc\u00e9s William Murdoch invent\u00f3 la l\u00e1mpara de gas, que ilumin\u00f3 el exterior de la fundici\u00f3n del SoHo. En 1807 se inaugur\u00f3 la primera calle de gas en Londres. En 1816, Baltimore se convirti\u00f3 en la primera ciudad de Estados Unidos en instalar farolas de gas. Par\u00eds le sigui\u00f3 en 1820. En esta \u00e9poca, el gas se instalaba a trav\u00e9s de tuber\u00edas hasta las farolas de gas colocadas en los postes de electricidad. Cada noche, una cuadrilla especial encend\u00eda las farolas y, cada ma\u00f1ana, volv\u00edan a apagar las luces. As\u00ed continu\u00f3 hasta que se invent\u00f3 el encendido de las farolas al liberar el gas que conten\u00edan.<\/div>\n<div data-zone-id=\"0\" data-line-index=\"2\">No fue hasta que Thomas Edison cre\u00f3 un vac\u00edo puro en la bombilla que cambi\u00f3 el futuro del alumbrado p\u00fablico para el mundo. La l\u00e1mpara incandescente de filamento de carbono de Edison se introdujo en 1879 e impuls\u00f3 el desarrollo del alumbrado p\u00fablico. Esto dio un gran impulso al posterior desarrollo del alumbrado p\u00fablico. La primera ciudad de EE.UU. en demostrar con \u00e9xito el alumbrado p\u00fablico el\u00e9ctrico fue Cleveland, Ohio, con 12 farolas el\u00e9ctricas alrededor del sistema de v\u00edas p\u00fablicas cuadradas el 29 de abril de 1879.<\/div>\n<div data-zone-id=\"0\" data-line-index=\"3\">En la d\u00e9cada de 1880, Indiana fue la primera ciudad de Estados Unidos en introducir el alumbrado p\u00fablico el\u00e9ctrico. As\u00ed empez\u00f3 el alumbrado p\u00fablico, con la instalaci\u00f3n de l\u00e1mparas de arco, tambi\u00e9n conocidas como velas de Yablochkov, en Par\u00eds en 1878. Tres a\u00f1os m\u00e1s tarde, se utilizaban 4.000 de estas l\u00e1mparas el\u00e9ctricas p\u00fablicas, que sustitu\u00edan a las l\u00e1mparas de gas instaladas en los postes. Pero el inconveniente de las l\u00e1mparas de arco era que emit\u00edan una luz fuerte y cegadora y no duraban mucho. Con el tiempo, fueron sustituidas por l\u00e1mparas incandescentes m\u00e1s baratas, brillantes y duraderas. Pero, a d\u00eda de hoy, las l\u00e1mparas de arco siguen siendo \u00fatiles en determinadas instalaciones industriales.<\/div>\n<div class=\"row\"  id=\"row-1568436301\">\n\n\t<div

XX<\/h2>\n<div data-zone-id=\"0\" data-line-index=\"1\">A principios del siglo XX, se sab\u00eda que las l\u00e1mparas originales de gas o metano provocaban incendios. As\u00ed que los fabricantes de farolas buscaban una forma m\u00e1s segura y eficaz de iluminar las calles. No fue hasta las d\u00e9cadas de 1930 y 1940 cuando se popularizaron las l\u00e1mparas fluorescentes e incandescentes. Fue entonces cuando empezaron a florecer los viajes a motor. En 1930 se popularizaron las l\u00e1mparas de sodio de baja presi\u00f3n, cuyo alumbrado p\u00fablico consist\u00eda en una vaina exterior desmontable y una capa de vac\u00edo como aislante. Esto permit\u00eda mantener el sodio en forma de vapor a altas temperaturas. A principios del siglo XX, las calles con alumbrado se llamaban carreteras blancas. Hasta 1962 no se desarrollaron los primeros diodos emisores de luz (LED) pr\u00e1cticos de espectro visible, y en 1965 las l\u00e1mparas de sodio de alta presi\u00f3n (HID) aportaron un color y una eficacia superiores a sus hom\u00f3logas de baja presi\u00f3n. Para entonces, el alumbrado p\u00fablico ya estaba tomando forma.<\/div>\n<div data-zone-id=\"0\" data-line-index=\"2\">\n<h2>El alumbrado p\u00fablico en el siglo XXI<\/h2>\n<\/div>\n<div data-zone-id=\"0\" data-line-index=\"3\">La invenci\u00f3n del alumbrado p\u00fablico LED en el siglo XXI podr\u00eda considerarse un gran paso adelante para las luces led p\u00fablicas. A partir de ese momento, el alumbrado p\u00fablico LED se convirti\u00f3 en algo habitual, y la tecnolog\u00eda de ahorro de energ\u00eda LED floreci\u00f3. La implantaci\u00f3n del alumbrado p\u00fablico con led tambi\u00e9n ofrece un mayor control y versatilidad. Las farolas led son de bajo coste y mantenimiento, y tambi\u00e9n permiten a los clientes especificar la temperatura de color, la potencia, etc., para adaptarse a cualquier aplicaci\u00f3n. Antes, las farolas de led eran caras, con todo lo que se habla de utilizar m\u00e1s energ\u00eda verde y reducir la huella de carbono. Muchas ciudades han adoptado la iluminaci\u00f3n LED como forma de ahorrar dinero y ayudar al medio ambiente al mismo tiempo. As\u00ed que el alumbrado p\u00fablico con LED est\u00e1 creciendo r\u00e1pidamente y se est\u00e1 utilizando de forma generalizada. Estudios recientes realizados en Los \u00c1ngeles han demostrado que los \u00edndices de delincuencia han disminuido tras la instalaci\u00f3n del alumbrado p\u00fablico LED. La superficie iluminada es mayor que la que se obtiene al caminar bajo las farolas tradicionales. Esto hace que la gente se sienta y est\u00e9 m\u00e1s segura cuando camina hacia su casa a altas horas de la noche.<\/div>\n<h2>Conclusi\u00f3n<\/h2>\n<p>As\u00ed ha evolucionado el alumbrado p\u00fablico de las calles en los \u00faltimos trescientos a\u00f1os. Y ahora vuelven a popularizarse las luces inteligentes. Las luces inteligentes son las que detectan la presencia de peatones y veh\u00edculos al anochecer y se encienden y apagan autom\u00e1ticamente. Estas luces inteligentes son incluso m\u00e1s eficientes energ\u00e9ticamente que las farolas LED. Con el desarrollo de la tecnolog\u00eda actual, creo que las luces inteligentes se popularizar\u00e1n cada vez m\u00e1s r\u00e1pido. Esto se debe a que es un signo del progreso continuo de las personas.<\/p>\n<p>Y el alumbrado p\u00fablico tambi\u00e9n ser\u00e1 una preocupaci\u00f3n constante en el futuro. No es s\u00f3lo que el antiguo alumbrado p\u00fablico est\u00e9 obsoleto porque consume mucha energ\u00eda. Tambi\u00e9n es porque no es inteligente y causa contaminaci\u00f3n blanca en muchos lugares. Muchos tipos de alumbrado p\u00fablico tambi\u00e9n pueden tener problemas.<\/p>","protected":false},"excerpt":{"rendered":"<p>Hoy en d\u00eda, el alumbrado p\u00fablico se enciende puntualmente todas las noches oscuras, lo que supone un avance tecnol\u00f3gico. \u00bfQuiere saber c\u00f3mo ha evolucionado el alumbrado? \u00bfO te has preguntado alguna vez c\u00f3mo se iluminaba la gente en la oscuridad hace cien a\u00f1os?
