Flicker consists of the frequency and modulation. Flicker can lead to annoyance, fatigue, headaches and difficulty concentrating. It is caused by too low a frequency and\/or modulation of light. At a frequency of 50Hz, the light goes on and off every 0.02 seconds. The frequency at 50Hz is visible to many people and hereby causes the previously mentioned inconveniences. This flicker is also perceptible to animals and is also disturbing. In addition to the base frequency, frequency modulation is also an important aspect that determines the level of flicker. Modulation refers to the intensity of each wave. A Flicker meter is used to measure frequency and modulation. Through the Flicker Index, the cycles are displayed graphically and the degree of disruptive flicker is illustrated.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-72c5635 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"72c5635\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-25904c7\" data-id=\"25904c7\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-c7cc2e4 elementor-widget elementor-widget-image\" data-id=\"c7cc2e4\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"300\" height=\"300\" src=\"https:\/\/clearlight.eu\/wp-content\/uploads\/2022\/08\/Flicker-Stroboscopisch-effect-led.webp\" class=\"attachment-medium size-medium wp-image-14564\" alt=\"\" srcset=\"https:\/\/clearlight.eu\/wp-content\/uploads\/2022\/08\/Flicker-Stroboscopisch-effect-led.webp 300w, https:\/\/clearlight.eu\/wp-content\/uploads\/2022\/08\/Flicker-Stroboscopisch-effect-led-150x150.webp 150w, https:\/\/clearlight.eu\/wp-content\/uploads\/2022\/08\/Flicker-Stroboscopisch-effect-led-100x100.webp 100w, https:\/\/clearlight.eu\/wp-content\/uploads\/2022\/08\/Flicker-Stroboscopisch-effect-led-80x80.webp 80w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-6130566\" data-id=\"6130566\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-0c99cc9 elementor-widget elementor-widget-text-editor\" data-id=\"0c99cc9\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><em>On the IES website, this image is shown to graphically represent the creation of the Flicker index.<\/em><\/p>\n<p><em>The cycles are analyzed by modulation and frequency.<\/em><\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-9f184d3 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"9f184d3\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-bbbab05\" data-id=\"bbbab05\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-9fb7bda elementor-widget elementor-widget-heading\" data-id=\"9fb7bda\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">What causes the stroboscopic lighting effect?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c759ad6 elementor-widget elementor-widget-text-editor\" data-id=\"c759ad6\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Where previously incandescent and halogen spotlights and other heat emitters were the dominant light sources, now LED is. A heat radiator depends on a thermal process. This process creates emitted radiation that becomes visible to the human eye under certain conditions. It is a relatively slow process in which the stroboscopic effect occurs less. Since the electrical grid in the Netherlands operates at 50Hz, and this frequency was transferred 1 to 1 to the radiant heater. LEDs are not heat emitters, which means there is no slow thermal effect where the frequency amplitude is somewhat smoothed. The on\/off switching at every 0.02 seconds is therefore visible and disruptive. A well-developed LED Driver overcomes this problem.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ce32209 elementor-widget elementor-widget-text-editor\" data-id=\"ce32209\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><strong>Want to know more about LED Drivers?<\/strong><\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f0995da elementor-align-center elementor-widget elementor-widget-button\" data-id=\"f0995da\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/clearlight.eu\/led-driver-wat-is-het-en-hoe-werkt-het\/\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">LED Drivers<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-a0ea249 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"a0ea249\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-9424235\" data-id=\"9424235\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-c449e65 elementor-widget elementor-widget-image\" data-id=\"c449e65\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"461\" height=\"376\" src=\"https:\/\/clearlight.eu\/wp-content\/uploads\/2022\/08\/Flicker-safety-Stroboscopisch-effect-led.webp\" class=\"attachment-full size-full wp-image-14565\" alt=\"\" srcset=\"https:\/\/clearlight.eu\/wp-content\/uploads\/2022\/08\/Flicker-safety-Stroboscopisch-effect-led.webp 461w, https:\/\/clearlight.eu\/wp-content\/uploads\/2022\/08\/Flicker-safety-Stroboscopisch-effect-led-300x245.webp 300w, https:\/\/clearlight.eu\/wp-content\/uploads\/2022\/08\/Flicker-safety-Stroboscopisch-effect-led-80x65.webp 80w\" sizes=\"(max-width: 461px) 100vw, 461px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-7e132e9\" data-id=\"7e132e9\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-c38ea7e elementor-widget elementor-widget-heading\" data-id=\"c38ea7e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">What are the implications of the stroboscopic lighting effect?<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c43499b elementor-widget elementor-widget-text-editor\" data-id=\"c43499b\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Flicker does not affect everyone the same way.

This concentration takes energy and creates extra effort. Both from visible (on\/off) and invisible flicker (modulation) can cause health problems. These complaints are characterized as: incorrect work posture, eyestrain, irritation, decreased concentration, reduced vision, headaches and in some cases much more serious complaints. Even if a person is not experiencing conscious symptoms from the stroboscopic effect now. It does not mean that the symptoms are not there, or that they are not going to arise. Established long-term health complaints include chronic fatigue, chronic migraines, light sensitivity, anxiety, depression and irritability.
