The index is measured on a scale of 0-100, where a perfect 100 means that the color of an object under a light source appears to be the same as under natural sunlight. A CRI range below 80 is generally considered &#8220;poor,&#8221; while a range above 90 is considered &#8220;very good.&#8221;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-part-2-color-rendering-index-cri-for-measuring-artificial-white-light-sources\">Parte 2: \u00cdndice de restitui\u00e7\u00e3o de cor (IRC) para medi\u00e7\u00e3o de fontes de luz branca artificial<\/h3>\n\n\n\n<p>As fontes de luz podem ser classificadas em fontes de luz artificial ou fontes de luz natural. Normalmente, s\u00f3 nos preocupamos com a qualidade da cor das formas de ilumina\u00e7\u00e3o artificial, como os LED e as fluorescentes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-is-the-relationship-between-cri-and-led-lighting\">Qual \u00e9 a rela\u00e7\u00e3o entre CRI e ilumina\u00e7\u00e3o LED?<\/h2>\n\n\n\n<p>A ilumina\u00e7\u00e3o LED que utiliza em sua casa pode ter um impacto profundo no aspeto da sua divis\u00e3o. Este facto \u00e9 frequentemente atribu\u00eddo ao \u00edndice de restitui\u00e7\u00e3o de cores.<\/p>\n\n\n\n<p>Also known as CRI, this index measures the ability of a light source to reveal the color of an object compared to natural light sources, such as sunlight through a window. In other words, it is a measurement of light in relation to how light affects the appearance of color. The range also depends on the &#8220;temperature&#8221; of the light.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-is-the-importance-of-cri-for-lighting-fixtures\">Qual \u00e9 a import\u00e2ncia do CRI para as lumin\u00e1rias?<\/h2>\n\n\n\n<p>O CRI da ilumina\u00e7\u00e3o desempenha um papel importante na escolha da temperatura de cor correcta para a sua casa.
