De fato, tendemos a pensar que a luz branca \u00e9 mais aparente e a amarela \u00e9 mais fraca. Mas as luzes da rua s\u00e3o amarelas; ser\u00e1 que \u00e9 para dar um toque de calor quando voc\u00ea volta \u00e0 noite? Qual \u00e9 a diferen\u00e7a entre as luzes de rua amarelas e brancas? A seguir, voc\u00ea ser\u00e1 apresentado em detalhes.<\/p>\n<p><iframe title=\"Por que as luzes das ruas s\u00e3o amarelas? Ci\u00eancia do dia a dia\" width=\"1020\" height=\"574\" src=\"https:\/\/www.youtube.com\/embed\/_EF0IdRfZNc?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/p>\n<h2>Por que as luzes da rua geralmente s\u00e3o amarelas ou laranja?<\/h2>\n<p>Por que as luzes da rua s\u00e3o amarelas em vez de brancas? Em primeiro lugar, precisamos descobrir por que os postes de ilumina\u00e7\u00e3o p\u00fablica emitem luzes amarelas. Isso \u00e9 determinado pela l\u00e2mpada usada. A maioria das l\u00e2mpadas de rua \u00e9 feita de vapor de s\u00f3dio, que se divide principalmente em s\u00f3dio de alta press\u00e3o (HPS) e s\u00f3dio de baixa press\u00e3o (LPS). O s\u00f3dio de alta press\u00e3o \u00e9 mais usado porque tem maior efici\u00eancia luminosa, consome menos energia e dura mais tempo. Al\u00e9m disso, sua permeabilidade \u00e0 neblina tamb\u00e9m \u00e9 excelente, o que torna mais seguro viajar \u00e0 noite e reduz a probabilidade de acidentes de tr\u00e2nsito.<br \/>\nMas a l\u00e2mpada de s\u00f3dio de alta press\u00e3o tamb\u00e9m tem a desvantagem da baixa reprodu\u00e7\u00e3o de cores. Ela parece branca quando aberta pela primeira vez e fica amarela depois de algum tempo. N\u00e3o importa qual seja o objeto, ele \u00e9 amarelo. Ao ler isso, voc\u00ea pode estar se perguntando: por que n\u00e3o usar uma l\u00e2mpada incandescente mais clara? Isso se deve ao fato de que, para a ilumina\u00e7\u00e3o de estradas, a reprodu\u00e7\u00e3o de cores n\u00e3o \u00e9 t\u00e3o importante. No processo de dirigir \u00e0 noite, voc\u00ea s\u00f3 precisa ver o tamanho e a forma do carro que se aproxima, n\u00e3o a cor do carro.<\/p>\n<h2>Por que o s\u00f3dio foi usado na ilumina\u00e7\u00e3o p\u00fablica?<\/h2>\n<p>Simplesmente, a luz da rua \u00e9 amarela ou laranja porque usa s\u00f3dio de alta press\u00e3o; Por que o s\u00f3dio foi usado na ilumina\u00e7\u00e3o p\u00fablica?<br \/>\nAntes de mais nada, vamos dar uma olhada em uma tabela com a vida \u00fatil nominal m\u00e9dia e os l\u00famens por watt de diferentes tipos de l\u00e2mpadas.<\/p>\n<table>\n<thead>\n<tr>\n<th>Tipos de l\u00e2mpadas<\/th>\n<th>Vida nominal m\u00e9dia<\/th>\n<th>L\u00famens por watt<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Incandescente<\/td>\n<td>750 a 2.000 horas<\/td>\n<td>12-18<\/td>\n<\/tr>\n<tr>\n<td>HPS<\/td>\n<td>20.000 a 24.000 horas<\/td>\n<td>80-140<\/td>\n<\/tr>\n<tr>\n<td>LED<\/td>\n<td>40.000 a 50.000 horas<\/td>\n<td>30-90<\/td>\n<\/tr>\n<tr>\n<td>Halog\u00eanio<\/td>\n<td>2.000 a 4.000 horas<\/td>\n<td>10-20<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Podemos ver claramente que a HPS tem cerca de sete vezes mais l\u00famens por watt do que as l\u00e2mpadas incandescentes e pode durar at\u00e9 24.000 horas. Portanto, a luz de s\u00f3dio \u00e9 suficientemente brilhante e tem uma longa vida \u00fatil.<br \/>\nOutro motivo importante \u00e9 que ele consome menos energia. Porque ela produz apenas luz vis\u00edvel aos olhos humanos. As l\u00e2mpadas incandescentes produzem luz em todas as faixas de frequ\u00eancia, do infravermelho ao ultravioleta, o que consome muita energia.<br \/>\nPortanto, as l\u00e2mpadas de s\u00f3dio t\u00eam vantagens aparentes em termos de custo e efici\u00eancia em compara\u00e7\u00e3o com outras l\u00e2mpadas, ent\u00e3o por que n\u00e3o usar l\u00e2mpadas de s\u00f3dio? Desde a d\u00e9cada de 1980, as l\u00e2mpadas HPS t\u00eam sido amplamente usadas em ilumina\u00e7\u00e3o p\u00fablica, e as pessoas gradualmente se acostumaram com as luzes amarelas das ruas.<\/p>\n<h2>Por que as luzes de rua de LED n\u00e3o s\u00e3o usadas?<\/h2>\n<p>As l\u00e2mpadas incandescentes n\u00e3o s\u00e3o usadas em postes de ilumina\u00e7\u00e3o p\u00fablica por motivos de efici\u00eancia, mas por que n\u00e3o s\u00e3o usadas l\u00e2mpadas de rua de LED? Afinal, quando olhamos a tabela acima, o LED \u00e9 eficiente e tem vida \u00fatil m\u00e9dia mais longa. Dois motivos principais s\u00e3o descritos abaixo.<\/p>\n<p><img decoding=\"async\" class=\"wp-image-1837 alignnone\" src=\"https:\/\/kanglight.com\/wp-content\/uploads\/2021\/05\/led-street-light-03_featured-1-300x131.png\" alt=\"luz de rua\" width=\"546\" height=\"238\" srcset=\"https:\/\/kanglight.com\/wp-content\/uploads\/2021\/05\/led-street-light-03_featured-1-300x131.png 300w, https:\/\/kanglight.com\/wp-content\/uploads\/2021\/05\/led-street-light-03_featured-1-768x336.png 768w, https:\/\/kanglight.com\/wp-content\/uploads\/2021\/05\/led-street-light-03_featured-1.png 800w\" sizes=\"(max-width: 546px) 100vw, 546px\" \/><\/p>\n<h3>1. Tempo de apari\u00e7\u00e3o<\/h3>\n<p>De fato, foi somente em 1962 que Nick Holonyak inventou a primeira luz LED vis\u00edvel. Isso \u00e9 muito mais tarde do que outros tipos de l\u00e2mpadas. Nessa \u00e9poca, muitas luzes de rua j\u00e1 estavam instaladas. A aplica\u00e7\u00e3o generalizada de novas tecnologias requer pr\u00e1tica, que n\u00e3o pode ser realizada em um curto per\u00edodo.<\/p>\n<h3>2. Custo<\/h3>\n<p>E o custo das l\u00e2mpadas LED tamb\u00e9m \u00e9 alto. Uma l\u00e2mpada de LED custava cerca de $200, o que era muito dinheiro na \u00e9poca. E a ilumina\u00e7\u00e3o p\u00fablica requer n\u00e3o apenas l\u00e2mpadas, mas tamb\u00e9m postes e outros materiais. A instala\u00e7\u00e3o tamb\u00e9m \u00e9 trabalhosa.<br \/>\nMas, com o passar dos anos, o pre\u00e7o dos LEDs vem caindo, e algumas luzes de rua come\u00e7aram a usar luzes de LED. N\u00e3o h\u00e1 d\u00favida de que, com o avan\u00e7o da tecnologia, veremos a tecnologia LED ser aplicada em mais campos. Mas precisamos saber que, se n\u00e3o houver nenhuma desvantagem aparente das luzes de s\u00f3dio, as luzes de LED n\u00e3o substituir\u00e3o as luzes de s\u00f3dio.<\/p>\n<h2>O melhor fabricante de l\u00e2mpadas LED para ilumina\u00e7\u00e3o p\u00fablica<\/h2>\n<p>Se voc\u00ea quiser comprar l\u00e2mpadas de rua de LED de alta qualidade, ter\u00e1 de escolher um fabricante confi\u00e1vel de l\u00e2mpadas de rua de LED e, ent\u00e3o, sua jornada de compra ser\u00e1 metade da batalha.<br \/>\nA Kanglight \u00e9 um dos melhores fabricantes de ilumina\u00e7\u00e3o p\u00fablica de LED da China.
