Qual \u00e9 o \u00c2ngulo de Corte (de uma Lumin\u00e1ria)<\/h2>

O \u00e2ngulo de corte de um lumin\u00e1ria \u00e9 o \u00e2ngulo em que a luz emitida por uma lumin\u00e1ria \u00e9 direcionada e controlada. \u00c9 medido a partir do ponto mais baixo para cima, entre o eixo vertical e a primeira fileira onde a fonte de luz nua (l\u00e2mpada) n\u00e3o \u00e9 vis\u00edvel. O \u00e2ngulo de corte ajuda a determinar o n\u00edvel de ofuscamento e o conforto visual proporcionado pela lumin\u00e1ria.<\/p>

A Illuminating Engineering Society (IES) define um dispositivo de corte como tendo limites de intensidade espec\u00edficos em ou acima de certos \u00e2ngulos. Por exemplo, um lumin\u00e1ria de \u00e2ngulo de corte completo bloqueia completamente a luz de ser emitida acima do plano horizontal, minimizando a polui\u00e7\u00e3o luminosa e reduzindo o ofuscamento. Por outro lado, uma lumin\u00e1ria de \u00e2ngulo de semi-corte permite que uma pequena quantidade de luz seja emitida acima do plano horizontal, equilibrando o controle do espalhamento de luz e fornecendo alguma distribui\u00e7\u00e3o de luz para cima. Por fim, uma lumin\u00e1ria de \u00e2ngulo sem corte n\u00e3o possui restri\u00e7\u00f5es na distribui\u00e7\u00e3o de luz, emitindo luz em todas as dire\u00e7\u00f5es.<\/p>

O \u00e2ngulo de corte espec\u00edfico e suas varia\u00e7\u00f5es podem variar dependendo da aplica\u00e7\u00e3o e dos padr\u00f5es de ilumina\u00e7\u00e3o. Diferentes lumin\u00e1rias podem ter \u00e2ngulos de corte diferentes com base em seu design e uso pretendido.<\/p>

Perguntas Frequentes<\/h2>\n\n

Qual \u00e9 a defini\u00e7\u00e3o de uma lumin\u00e1ria de corte<\/h3><\/div><\/div>\n\n

Uma lumin\u00e1ria de corte, tamb\u00e9m conhecida como lumin\u00e1ria de corte, \u00e9 um tipo de lumin\u00e1ria que possui uma distribui\u00e7\u00e3o de luz espec\u00edfica. Nesse tipo de lumin\u00e1ria, a intensidade de candelas n\u00e3o excede 2,5% da sa\u00edda luminosa inicial nominal das l\u00e2mpadas em um \u00e2ngulo de 90 graus acima do nadir. Al\u00e9m disso, n\u00e3o excede 10% da sa\u00edda luminosa inicial nominal das l\u00e2mpadas em um \u00e2ngulo vertical de 80 graus acima do nadir.<\/p><\/div><\/div><\/div><\/div>\n\n

O que significa corte total<\/h3><\/div><\/div>\n\n

Corte total refere-se \u00e0 condi\u00e7\u00e3o em que a luz emitida pela lumin\u00e1ria n\u00e3o ultrapassa sua parte inferior.<\/p><\/div><\/div><\/div><\/div>\n\n

Qual \u00e9 a diferen\u00e7a entre semi-corte e corte total<\/h3><\/div><\/div>\n\n

As lumin\u00e1rias de parede tradicionais distribuem luz em todas as dire\u00e7\u00f5es, enquanto as lumin\u00e1rias de parede de semi-corte direcionam a luz para baixo e para fora. Por outro lado, as lumin\u00e1rias de corte total restringem a distribui\u00e7\u00e3o de luz abaixo da lumin\u00e1ria. As lumin\u00e1rias de corte total s\u00e3o projetadas para cumprir regulamentos de c\u00e9u escuro e minimizar efetivamente a invas\u00e3o de luz e a polui\u00e7\u00e3o luminosa.<\/p><\/div><\/div><\/div><\/div>\n\n

O que \u00e9 \u00e2ngulo de corte<\/h3><\/div><\/div>\n\n

O \u00e2ngulo de corte refere-se ao \u00e2ngulo no qual a fonte de luz nua n\u00e3o \u00e9 mais vis\u00edvel, medido a partir do ponto mais baixo entre uma linha vertical do centro da l\u00e2mpada estendida at\u00e9 o ch\u00e3o e a primeira linha de vis\u00e3o.<\/p><\/div><\/div><\/div><\/div>\n\n

Por que s\u00e3o recomendados lumin\u00e1rias totalmente protegidas<\/h3><\/div><\/div>\n\n

Uma lumin\u00e1ria totalmente protegida \u00e9 projetada de forma que a fonte de luz n\u00e3o seja vis\u00edvel para pessoas ou animais selvagens nas proximidades. Ao usar ilumina\u00e7\u00e3o totalmente protegida, voc\u00ea pode efetivamente impedir que a luz invada a propriedade de seus vizinhos, al\u00e9m de minimizar o ofuscamento e o brilho do c\u00e9u.<\/p><\/div><\/div><\/div><\/div>\n\n

O que \u00e9 uma lumin\u00e1ria totalmente protegida<\/h3><\/div><\/div>\n\n

\u201cTotalmente protegida\u201d refere-se a lumin\u00e1rias que foram projetadas de modo que os raios de luz emitidos, seja diretamente da l\u00e2mpada ou indiretamente da lumin\u00e1ria, sejam direcionados para baixo, abaixo de um plano horizontal. Essa prote\u00e7\u00e3o \u00e9 alcan\u00e7ada posicionando o ponto mais baixo da lumin\u00e1ria onde a luz \u00e9 emitida abaixo desse plano.<\/p><\/div><\/div><\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"
