This standard also provides risk classification criteria for products using light sources.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">IEC TR 62778, on the other hand, is a technical report that provides guidelines for the assessment of photobiological risks associated with LED light sources.<br>Although this standard is initially intended for tests on sources, it can be too critical when applied to luminaires integrating these sources (measurement conducted at a distance of 200mm). Additionally, design features of luminaires, such as reflectors or optical lenses, change the properties of the emitted light and, thus, the measurement results.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The objective of IEC 62471-7:2023, proposed by UF34, is to integrate the application of the product into the optical risk assessment method.<br>It specifies an assessment of the photobiological safety of electrical light sources and luminaires in normal use as well as certain basic product requirements. It applies to electrical light sources and luminaires that emit radiation mainly in the visible spectral range (from 380 nm to 780 nm) and are used to illuminate spaces or objects or for signaling.<br>In IEC 62471-7, tests on light sources are specified, and the standard also describes how to extend the test results from sources to luminaires. This extension depends on the luminance values of the source and the product application. However, additional testing of luminaires may be necessary for an accurate risk assessment.<\/p>\n<\/div><\/div><\/div>\n<\/details>\n\n\n\n<details class=\"wp-block-stackable-accordion stk-block-accordion stk-inner-blocks stk-block-content stk-block stk-6451a04 is-style-plain\" data-block-id=\"6451a04\"><style>.stk-6451a04{border-style:solid !important;border-color:#dfdad1 !important;border-top-width:0px !important;border-right-width:0px !important;border-bottom-width:1px !important;border-left-width:0px !important;padding-bottom:24px !important}<\/style>\n<summary class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-140e0f0 stk--container-small stk-block-accordion__heading\" data-v=\"4\" data-block-id=\"140e0f0\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-140e0f0-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-140e0f0-inner-blocks\">\n<div class=\"wp-block-stackable-icon-label stk-block-icon-label stk-block stk-b6d0777\" data-block-id=\"b6d0777\"><div class=\"stk-row stk-inner-blocks stk-block-content\">\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-75c0a98\" id=\"what-about-iec-62471-2006\" data-block-id=\"75c0a98\"><h2 class=\"stk-block-heading__text\">What about IEC 62471:2006?<\/h2><\/div>\n\n\n\n<div class=\"wp-block-stackable-icon stk-block-icon stk-block stk-6a74c81\" data-block-id=\"6a74c81\"><span class=\"stk--svg-wrapper\"><div class=\"stk--inner-svg\"><svg style=\"height:0;width:0\"><defs><linearGradient id=\"linear-gradient-6a74c81\" x1=\"0\" x2=\"100%\" y1=\"0\" y2=\"0\"><stop offset=\"0%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-6-a-74-c-81-color-1)\"><\/stop><stop offset=\"100%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-6-a-74-c-81-color-2)\"><\/stop><\/linearGradient><\/defs><\/svg><svg data-prefix=\"fas\" data-icon=\"chevron-down\" class=\"svg-inline--fa fa-chevron-down fa-w-14\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 448 512\" aria-hidden=\"true\" width=\"32\" height=\"32\"><path fill=\"currentColor\" d=\"M207.029 381.476L12.686 187.132c-9.373-9.373-9.373-24.569 0-33.941l22.667-22.667c9.357-9.357 24.522-9.375 33.901-.04L224 284.505l154.745-154.021c9.379-9.335 24.544-9.317 33.901.04l22.667 22.667c9.373 9.373 9.373 24.569 0 33.941L240.971 381.476c-9.373 9.372-24.569 9.372-33.942 0z\"><\/path><\/svg><\/div><\/span><\/div>\n<\/div><\/div>\n<\/div><\/div><\/summary>\n\n\n\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-6481baf stk-block-accordion__content\" data-v=\"4\" data-block-id=\"6481baf\"><style>.stk-6481baf-container{padding-top:0px !important;padding-right:0px !important;padding-bottom:0px !important;padding-left:0px !important}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-6481baf-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-6481baf-inner-blocks\">\n<div class=\"wp-block-stackable-text stk-block-text stk-block stk-d05e60e\" data-block-id=\"d05e60e\"><p class=\"stk-block-text__text\">This new IEC 62471-7 standard does not replace IEC 62471:2006 &#8211; which will become IEC 62471-1 &#8211; which remains applicable.
