Prologue: The Truth About Indoor Lighting We Never Knew, and Brain Health<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What if the lighting we sit under at our desks every day could do more than simply brighten the room, and actually boost our brain\u2019s memory and cognitive performance? Modern people spend more than half of each day under artificial LED lighting. However, most ordinary LED lights lack the near-infrared wavelengths that natural sunlight is rich in, which can leave mitochondria, the powerhouses of our cells, more easily fatigued and reduce energy production. What if the desk lamp in your study room or the lighting in your office also emitted near-infrared light that activates brain cells? How would our daily lives change?<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-media-text is-stacked-on-mobile\"><figure class=\"wp-block-media-text__media\"><img decoding=\"async\" src=\"https:\/\/ledon.kr\/wp-content\/uploads\/2026\/10\/461.jpg\" alt=\"A student pondering under a desk lamp, with a neural network inside the brain: can everyday lighting wake up your brain?\" class=\"wp-image-2348 size-full\"\/><\/figure><div class=\"wp-block-media-text__content\">\n<p class=\"wp-block-paragraph\"><strong>[01:00 &#8211; 02:15] Part 2. Technical Innovation: Broadband Near-Infrared (NIR) in a Single LED Chip<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">LEDON, a functional lighting specialist, focused on exactly this point. Until now, near-infrared technology has been used only in separate, dedicated irradiation devices that shine light on a specific part of the body, which limited its continuous use in everyday life. LEDON has developed a new technology that coats the surface of a white LED with its own proprietary light-conversion material. With this technology, the company succeeded in emitting broadband near-infrared light in the 700 to 900 nanometer range and white light simultaneously from \u2018a single LED chip.\u2019 Without adding a separate light-emitting chip, an innovative white light was born that lets you receive near-infrared energy naturally in the lighting environments you encounter every day, such as reading, studying, and computer work.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-media-text is-stacked-on-mobile\"><figure class=\"wp-block-media-text__media\"><img decoding=\"async\" src=\"https:\/\/ledon.kr\/wp-content\/uploads\/2026\/10\/462.jpg\" alt=\"Researchers testing a near-infrared desk lamp in a lab: the birth of broadband near-infrared lighting\" class=\"wp-image-2349 size-full\"\/><\/figure><div class=\"wp-block-media-text__content\">\n<p class=\"wp-block-paragraph\"><strong>[02:15 &#8211; 03:45] Part 3. KTC Human Application Test: The Secret Behind a 52% Reduction in Memory Errors (\u2605 Deep dive after 2:30)<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So what real change did this everyday light bring to our brains? To validate the technology, LEDON ran a four-week human application test at the Korea Testing Certification (KTC) institute. Participants performed a complex cognitive task in which they had to remember information shown on a screen and compare it with new information to make judgments. After four weeks of using the lighting, participants\u2019 memory test accuracy rose markedly, from 93.75% before use to 97.00%. Converted into an error rate, this fell from 6.25% to 3.00%, <strong>a remarkable change in which memory errors dropped by a full 52%<\/strong>. In addition, the index of the ability to process and distinguish multiple pieces of information at the same time also rose sharply, from 2.53 to 3.36.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-media-text is-stacked-on-mobile\"><figure class=\"wp-block-media-text__media\"><img decoding=\"async\" src=\"https:\/\/ledon.kr\/wp-content\/uploads\/2026\/10\/463.jpg\" alt=\"Illustration of a brain and the broadband near-infrared wavelength spectrum\" class=\"wp-image-2350 size-full\"\/><\/figure><div class=\"wp-block-media-text__content\">\n<p class=\"wp-block-paragraph\"><strong>[03:45 &#8211; 05:00] Part 4. Precision Brain Analysis: Increased Prefrontal Blood Flow and Brain Cell Activation<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Behind this improvement in memory were remarkable biological changes inside the brain. Brain measurements taken during the cognitive task confirmed a statistically significant increase in oxygen-carrying blood components in some regions of the \u2018prefrontal cortex,\u2019 the key area that governs thinking, judgment, and concentration. Near-infrared wavelengths penetrate deep through the skin and body tissue and stimulate the mitochondria of neurons in the prefrontal cortex. As mitochondrial ATP energy synthesis is activated and cerebral blood flow becomes smoother, brain cells are able to perform information-processing tasks in optimal condition.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-media-text is-stacked-on-mobile\"><figure class=\"wp-block-media-text__media\"><img decoding=\"async\" src=\"https:\/\/ledon.kr\/wp-content\/uploads\/2026\/10\/464.jpg\" alt=\"52% fewer memory errors after 4 weeks: a before-and-after infographic\" class=\"wp-image-2351 size-full\"\/><\/figure><div class=\"wp-block-media-text__content\">\n<p class=\"wp-block-paragraph\"><strong>[05:00 &#8211; 06:15] Part 5.

First, it plans to launch finished desk lamps for exam takers, students, and office workers who spend long hours at their desks. Going further, leveraging the excellent scalability of its single-LED-chip technology, the company is pursuing the supply of broadband near-infrared LED packages and light modules to lighting, home appliance, and healthcare companies.
