Volete sapere come si \u00e8 evoluta l'illuminazione? O vi siete mai chiesti come si illuminavano le persone al buio cento anni fa? La mancanza di luce naturale di notte negli ambienti urbani \u00e8 sempre stata un problema. Le notti buie possono rendere difficili gli spostamenti. Oppure, senza illuminazione pubblica, le persone avevano maggiori probabilit\u00e0 di essere aggredite o derubate di notte. Vediamo ora l'evoluzione storica dell'illuminazione pubblica.<\/div>\n<div data-zone-id=\"0\" data-line-index=\"1\">\n<div>Le prime forme di illuminazione pubblica erano costituite da oli vegetali o candele. Nell'antica Roma, i cittadini benestanti usavano lampade a olio vegetale per fare luce. I cittadini cinesi accendevano candele per fare luce. Ma \u00e8 difficile credere che la prima versione conosciuta di un lampione sia apparsa intorno al 140 a.C.! I Greci e i Romani illuminavano i sentieri e le strade fuori dalle loro case per scoraggiare i ladri e migliorare la visibilit\u00e0 e la sicurezza. Gli abitanti pi\u00f9 ricchi assumevano schiavi lanternieri per garantire che i lampioni fossero mantenuti luminosi e puliti per tutta la notte. Tuttavia, si trattava solo di illuminazione privata e non pubblica fino al 1417, quando il sindaco di Londra ordin\u00f2 a tutte le famiglie di appendere le loro lanterne all'esterno dopo il tramonto in inverno. Questo segn\u00f2 la prima illuminazione pubblica organizzata.<\/div>\n<\/div>\n<div class=\"row\"  id=\"row-1438305271\">\n\n\t<div id=\"col-1743990880\" 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_1081449722\">\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=\"ILLUMINAZIONE STRADALE A 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_1081449722 {\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-1575089877\" 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_1883457355\">\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=\"LUCE DI STRADA\" 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_1883457355 {\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\">Gli anni '80 e '50<\/h2>\n<div data-zone-id=\"0\" data-line-index=\"1\">Il grande inventore Benjamin Franklin introdusse per primo l'illuminazione pubblica negli Stati Uniti. Franklin fece diversi esperimenti con l'elettricit\u00e0 e invent\u00f2 il parafulmine. Propose poi di racchiudere le candele a olio di pegno in un contenitore di vetro con un lungo imbuto per il fumo e una fessura sottostante per far entrare l'aria. In questo modo, la candela sarebbe stata accesa all'interno del contenitore di vetro e difficilmente si sarebbe spenta anche con il vento. Questo \u00e8 il primo prototipo di lampione cittadino: la lampada a olio e cera. Poich\u00e9 Franklin era il direttore delle poste di Filadelfia, molti considerano quest'ultima come il luogo di nascita dell'illuminazione stradale negli Stati Uniti. Molti luoghi hanno scelto di utilizzare lampade a olio e cera fino al XIX secolo, quando il gas metano \u00e8 stato utilizzato per l'illuminazione pubblica negli Stati Uniti.<\/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\">L'illuminazione stradale nel XIX secolo<\/h2>\n<div data-zone-id=\"0\" data-line-index=\"1\">Nel XIX secolo era disponibile il gas metano e l'uso per l'illuminazione aument\u00f2. Nel 1802 l'inventore scozzese William Murdoch invent\u00f2 la lampada a gas, che illumin\u00f2 l'esterno della fonderia di SoHo. Nel 1807 fu inaugurata la prima strada a gas a Londra. Nel 1816, Baltimora divenne la prima citt\u00e0 degli Stati Uniti a installare lampioni a gas. Parigi segu\u00ec nel 1820. A quell'epoca, il gas veniva convogliato attraverso tubi in lampade a gas collocate sui pali dei servizi pubblici. Ogni notte una squadra speciale accendeva le lanterne e ogni mattina le spegneva di nuovo. Questa procedura continu\u00f2 fino all'invenzione di accendere le lampade rilasciando il gas in esse contenuto.<\/div>\n<div data-zone-id=\"0\" data-line-index=\"2\">Solo quando Thomas Edison cre\u00f2 un vuoto puro nella lampadina, cambi\u00f2 il futuro dell'illuminazione pubblica nel mondo. La lampada a incandescenza a filamento di carbonio di Edison fu introdotta nel 1879 e diede impulso allo sviluppo dell'illuminazione pubblica. Questo diede un grande impulso al successivo sviluppo dell'illuminazione pubblica. La prima citt\u00e0 degli Stati Uniti a dimostrare con successo l'esistenza di un'illuminazione pubblica elettrica fu Cleveland, nell'Ohio, con 12 luci elettriche intorno alla rete stradale pubblica di piazza il 29 aprile 1879.<\/div>\n<div data-zone-id=\"0\" data-line-index=\"3\">Negli anni Ottanta del XIX secolo, l'Indiana fu la prima citt\u00e0 degli Stati Uniti a introdurre l'illuminazione pubblica elettrica. L'illuminazione pubblica \u00e8 nata cos\u00ec, con l'installazione di lampade ad arco, note anche come candele Yablochkov, a Parigi nel 1878. Tre anni dopo, 4.000 di queste lampade pubbliche elettriche erano in uso, sostituendo di fatto le lampade a gas montate sui pali dei servizi pubblici. Ma lo svantaggio delle lampade ad arco era che emettevano una luce forte e accecante e non duravano a lungo. Col tempo, quindi, furono sostituite da lampade a incandescenza, pi\u00f9 economiche, pi\u00f9 luminose e pi\u00f9 durature. Tuttavia, ancora oggi le lampade ad arco sono utili in alcuni siti industriali.<\/div>\n<div class=\"row\"  id=\"row-1466344904\">\n\n\t<div id=\"col-767224263\" class=\"col medium-6 small-12

ventesimo secolo<\/h2>\n<div data-zone-id=\"0\" data-line-index=\"1\">All'inizio del XX secolo era noto che le lampade a gas o a metano originarie causavano incendi. I produttori di lampioni cercavano quindi un modo pi\u00f9 sicuro ed efficiente per illuminare le strade. Solo negli anni '30 e '40 si diffusero le lampade fluorescenti e a incandescenza. Fu allora che cominciarono a fiorire i viaggi in automobile. Nel 1930 si diffusero le lampade al sodio a bassa pressione, che consistevano in una guaina esterna rimovibile e in uno strato di vuoto per l'isolamento. Questo permetteva di mantenere il sodio sotto forma di vapore ad alte temperature. All'inizio del XX secolo, le strade illuminate erano chiamate strade bianche. Solo nel 1962 furono sviluppati i primi diodi ad emissione di luce nello spettro visibile (LED) e nel 1965 le lampade al sodio ad alta pressione (HID) portarono un colore e un'efficienza superiori rispetto alle loro controparti a bassa pressione. A quel punto, l'illuminazione pubblica stava gi\u00e0 prendendo forma.<\/div>\n<div data-zone-id=\"0\" data-line-index=\"2\">\n<h2>L'illuminazione stradale nel XXI secolo<\/h2>\n<\/div>\n<div data-zone-id=\"0\" data-line-index=\"3\">L'invenzione dell'illuminazione stradale a LED nel XXI secolo pu\u00f2 essere considerata un gigantesco passo avanti per le luci pubbliche a LED. Da quel momento in poi, l'illuminazione stradale a LED \u00e8 diventata di uso comune e la tecnologia di risparmio energetico a LED \u00e8 fiorita. L'implementazione dell'illuminazione stradale a LED offre anche un maggiore controllo e versatilit\u00e0. I lampioni a LED sono a basso costo e a bassa manutenzione e consentono ai clienti di specificare la temperatura del colore, la potenza, ecc. per adattarsi a qualsiasi applicazione. In precedenza le luci stradali a LED erano costose, con tutti i discorsi sull'utilizzo di energia verde e sulla riduzione dell'impronta di carbonio. Molte citt\u00e0 hanno adottato l'illuminazione a LED come un modo per risparmiare denaro e allo stesso tempo aiutare l'ambiente. L'illuminazione pubblica a LED sta quindi crescendo rapidamente e viene ampiamente utilizzata. Recenti studi condotti a Los Angeles hanno dimostrato che il tasso di criminalit\u00e0 \u00e8 diminuito dopo l'installazione dell'illuminazione pubblica a LED. L'area illuminata \u00e8 pi\u00f9 ampia rispetto a quella in cui si cammina sotto i lampioni tradizionali. Questo fa s\u00ec che le persone si sentano e siano pi\u00f9 sicure quando tornano a casa a tarda notte.<\/div>\n<h2>Conclusione<\/h2>\n<p>Ecco come si \u00e8 evoluta l'illuminazione pubblica stradale negli ultimi trecento anni. Ora le luci intelligenti stanno tornando in auge. Le luci intelligenti sono quelle che percepiscono i pedoni e i veicoli dopo il tramonto e si accendono e si spengono automaticamente. Queste luci intelligenti sono ancora pi\u00f9 efficienti dal punto di vista energetico dei lampioni a LED. Con lo sviluppo della tecnologia odierna, credo che le luci intelligenti diventeranno sempre pi\u00f9 popolari. Questo perch\u00e9 \u00e8 un segno del continuo progresso delle persone.<\/p>\n<p>Anche l'illuminazione pubblica sar\u00e0 una preoccupazione costante in futuro. Non si tratta solo del fatto che la vecchia illuminazione pubblica \u00e8 obsoleta perch\u00e9 consuma molta energia. \u00c8 anche perch\u00e9 non \u00e8 intelligente e causa inquinamento bianco in molti luoghi. Anche molti tipi di illuminazione pubblica possono presentare problemi.<\/p>","protected":false},"excerpt":{"rendered":"<p>Oggi l'illuminazione pubblica si accende puntualmente ogni notte buia, il che rappresenta un progresso tecnologico.
