O que \u00e9 Ballast<\/h2>

Um reator \u00e9 um dispositivo pequeno ou equipamento de controle que normalmente \u00e9 encontrado dentro de uma lumin\u00e1ria e fornece a voltagem necess\u00e1ria para ligar a luz e regular a quantidade de corrente que flui para a luz. <\/p>

Existem dois tipos principais de reatores comumente usados em lumin\u00e1rias: reatores magn\u00e9ticos e reatores eletr\u00f4nicos. Reatores magn\u00e9ticos, normalmente encontrados em lumin\u00e1rias fluorescentes mais antigas, s\u00e3o conhecidos pelo som de zumbido caracter\u00edstico quando as luzes est\u00e3o acesas. Eles s\u00e3o mais propensos a problemas e podem falhar com o tempo. Reatores eletr\u00f4nicos s\u00e3o mais comumente usados em lumin\u00e1rias mais novas ou aquelas que foram atualizadas. Esses reatores s\u00e3o considerados mais eficientes em termos de energia e mais silenciosos em compara\u00e7\u00e3o com os reatores magn\u00e9ticos. Tamb\u00e9m s\u00e3o menos propensos a problemas e falhas. <\/p>

Um reator \u00e9 um componente crucial que garante a opera\u00e7\u00e3o adequada e a estabilidade de l\u00e2mpadas de descarga el\u00e9trica, como fontes de luz fluorescentes e HID. Ele fornece as condi\u00e7\u00f5es de circuito necess\u00e1rias para ligar e operar a l\u00e2mpada, regula a sa\u00edda de luz e gerencia a distribui\u00e7\u00e3o de energia por toda a lumin\u00e1ria. Sem um reator, a l\u00e2mpada n\u00e3o ligar\u00e1 ou operar\u00e1 corretamente. O reator garante que a l\u00e2mpada permane\u00e7a acesa fornecendo a energia el\u00e9trica necess\u00e1ria para aquecer a lampada e evitar que suas partes internas morram prematuramente. <\/p>

Perguntas Frequentes<\/h2>\n\n

Como Voc\u00ea Pode Identificar se uma Lumin\u00e1ria Possui um Reator<\/h3><\/div><\/div>\n\n

Basta ligar a lumin\u00e1ria e tirar uma foto dela usando seu smartphone ou c\u00e2mera digital. Se a imagem resultante n\u00e3o mostrar faixas escuras, isso indica que a lumin\u00e1ria est\u00e1 equipada com um reator eletr\u00f4nico, que \u00e9 compat\u00edvel com tubos de LED de encaixe direto (com algumas exce\u00e7\u00f5es, conforme explicado na pr\u00f3xima se\u00e7\u00e3o).<\/p><\/div><\/div><\/div><\/div>\n\n

O que acontece se voc\u00ea n\u00e3o usar um reator<\/h3><\/div><\/div>\n\n

Sem um reator, uma l\u00e2mpada ou l\u00e2mpada incandescente experimentar\u00e1 um aumento significativo na sua corrente, levando a um comportamento incontrol\u00e1vel. A aus\u00eancia de um reator impede que a energia se estabilize, o que pode ser problem\u00e1tico quando essas l\u00e2mpadas est\u00e3o conectadas a fontes de alta pot\u00eancia. No entanto, com um reator em funcionamento, a energia \u00e9 regulada, evitando qualquer aumento repentino na corrente.<\/p><\/div><\/div><\/div><\/div>\n\n

O que Acontece se Eu N\u00e3o Bypassar o Reator em Luzes de LED<\/h3><\/div><\/div>\n\n

Voc\u00ea corre o risco de danificar os LEDs se n\u00e3o bypassar o reator em luzes de LED. O reator em luzes fluorescentes requer uma tens\u00e3o de partida significativamente maior (cerca de 600 V) para inici\u00e1-los, que rapidamente cai para a tens\u00e3o de linha regular. Dependendo das toler\u00e2ncias do circuito de LED, \u00e9 poss\u00edvel que os LEDs sejam destru\u00eddos.<\/p><\/div><\/div><\/div><\/div>\n\n

Posso Usar Bulbos de LED T8 em uma Lumin\u00e1ria T12<\/h3><\/div><\/div>\n\n

A principal diferen\u00e7a entre tubos T8 e T12 est\u00e1 em seu di\u00e2metro. Tubos T12 t\u00eam um di\u00e2metro de 1,5 polegadas, enquanto T8s t\u00eam apenas uma polegada de di\u00e2metro. Apesar dessa diferen\u00e7a, os tamanhos de soquetes, comprimentos e a dist\u00e2ncia entre os pinos permanecem os mesmos para ambos os tipos. Portanto, se voc\u00ea tentar instalar tubos de LED T8 em uma lumin\u00e1ria T12, eles ir\u00e3o encaixar perfeitamente sem problemas.<\/p><\/div><\/div><\/div><\/div>\n\n

Um Reator Ruim Pode Causar um Inc\u00eandio<\/h3><\/div><\/div>\n\n

O superaquecimento de luzes fluorescentes pode potencialmente levar a inc\u00eandios. O calor excessivo gerado pelo reator pode fazer com que materiais combust\u00edveis pr\u00f3ximos peguem fogo e at\u00e9 mesmo fazer com que o pr\u00f3prio reator exploda devido ao ac\u00famulo de gases.<\/p><\/div><\/div><\/div><\/div>\n\n

Por que Minha Luz Fluorescente N\u00e3o Est\u00e1 Funcionando Ap\u00f3s Trocar as L\u00e2mpadas<\/h3><\/div><\/div>\n\n

A falta de energia el\u00e9trica, um reator com defeito, um starter com problema ou l\u00e2mpadas queimadas podem fazer uma luz fluorescente parar de funcionar ap\u00f3s trocar as l\u00e2mpadas. \u00c9 importante primeiro verificar a energia, depois inspecionar o starter (se aplic\u00e1vel) e, por \u00faltimo, examinar as l\u00e2mpadas. Se nenhuma dessas etapas resolver o problema, pode ser necess\u00e1rio substituir o reator.<\/p><\/div><\/div><\/div><\/div>\n\n

Quanto Tempo Dura um Ballast de Luz<\/h3><\/div><\/div>\n\n

A vida \u00fatil t\u00edpica de um ballast fluorescente varia de 10 a 15 anos. \u00c9 importante notar que qualquer ballast que ultrapasse essa idade deve ser considerado com maior probabilidade de falha.<\/p><\/div><\/div><\/div><\/div>\n\n

Os Ballasts Consomem muita eletricidade<\/h3><\/div><\/div>\n\n

Ballasts padr\u00e3o geralmente consistem de um n\u00facleo e bobina. No caso de uma lumin\u00e1ria t\u00edpica com duas l\u00e2mpadas fluorescentes T-12 de 40 watts de 4 p\u00e9s, o pr\u00f3prio ballast consome aproximadamente 13 a 16 watts de eletricidade. Portanto, ao considerar o consumo total das duas l\u00e2mpadas junto com o ballast, chega a cerca de 93 a 96 watts.<\/p><\/div><\/div><\/div><\/div>\n\n

O que acontece se voc\u00ea colocar uma luz LED junto com o ballast<\/h3><\/div><\/div>\n\n

N\u00e3o h\u00e1 necessidade de se preocupar em usar o tubo LED errado para sua lumin\u00e1ria ao optar por um tubo compat\u00edvel com ballast. Isso porque, ao instalar esses tubos, voc\u00ea primeiro remover\u00e1 ou 'pular\u00e1' o ballast da lumin\u00e1ria. Assim, a energia do edif\u00edcio ir\u00e1 diretamente para as soquetes das l\u00e2mpadas, ignorando o ballast.<\/p><\/div><\/div><\/div><\/div>\n\n

Posso substituir diretamente tubos fluorescentes por LED<\/h3><\/div><\/div>\n\n

Sim, \u00e9 poss\u00edvel substituir tubos fluorescentes por tubos LED ou lumin\u00e1rias integradas de LED. Se voc\u00ea s\u00f3 precisa substituir as l\u00e2mpadas, tem a op\u00e7\u00e3o de usar tubos LED plug-and-play, de liga\u00e7\u00e3o direta ou h\u00edbridos. Entre essas op\u00e7\u00f5es, os tubos plug-and-play s\u00e3o os mais convenientes de instalar, pois n\u00e3o requerem reconfigura\u00e7\u00e3o do fio da lumin\u00e1ria.<\/p><\/div><\/div><\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"
