In particular, PISEO has developed a test bench that combines a module equipped with UV LED and D65 LED and associated with a luminance camera. This device allows to simulate the light of day and to apply to the samples tested the desired energy doses and then to characterize the variation of the brightness levels (luminance) over time up to &#8220;the extinction\u201d.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The device allows to carry out product benchmarks with a regular recording of the measure luminance after the application of variable energy doses according to the needs of the Customer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Thanks to their knowledge of luminescent materials and the characterization of illumination systems, PISEO experts can also assist the Customer in defining the test program, in interpreting the results obtained and, if necessary, in improving the performance of the tested products through consulting on material formulation.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"275\" height=\"155\" src=\"https:\/\/piseo.fr\/wp-content\/uploads\/2020\/07\/phosphorescent.jpg\" alt=\"phosphorescent\" class=\"wp-image-3291\" srcset=\"https:\/\/piseo.fr\/wp-content\/uploads\/2020\/07\/phosphorescent.jpg 275w, https:\/\/piseo.fr\/wp-content\/uploads\/2020\/07\/phosphorescent-150x85.jpg 150w, https:\/\/piseo.fr\/wp-content\/uploads\/2020\/07\/phosphorescent-160x90.jpg 160w\" sizes=\"auto, (max-width: 275px) 100vw, 275px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">Note: Luminous decreasing are always compared regardless of the perception of the eye, but a red emission will be perceived much shorter than a green emission.
