Għaliex it-teptip tad-dawl tat-tubu LED?
As modern energy-efficient lighting technologies proliferate in our environment, so does awareness of their impact on biology and even technology. The rapid development and assimilation of LED lighting, often without clear standards, may lead to lighting flickering and adversely affect it. Many organisations and industry professionals across disciplines, including international standards bodies and regulators, are working to measure, understand and appropriately manage flicker.
1. Għaliex is-sors tad-dawl LED teptip?
1. Sorsi tad-dawl LED huma storja differenti. Ibbażati fuq semikondutturi, jirrispondu malajr għall-bidliet tal-enerġija, filwaqt li s-sistemi tal-enerġija u s-sewwieqa użati b'mod komuni jistgħu jiġġeneraw teptip eċċessiv.
2. Flicker kien madwar mill-invenzjoni ta ' sorsi tad-dawl li jaħdmu bl-AC (kurrent alternanti). Bidla fil-fażi tal-enerġija tal-provvista tipproduċi bidla perjodika korrispondenti rapida fir-radjazzjoni tad-dawl emess u l-intensità jew il-luminożità tal-illuminazzjoni li tirriżulta. Is-sistemi tad-dawl inkandexxenti tradizzjonali huma affettwati, iżda mhux b'mod sinifikanti, minħabba li l-filament huwa relattivament bil-mod biex jirrispondi għall-bidliet fil-qawwa. Sorsi tad-dawl oħra, bħal tubi fluworexxenti jew bozoz ta 'skarigu oħra, għandhom ħin ta' rispons mgħaġġel, għalhekk il-bidliet huma aktar notevoli għall-osservatur.
2. Kif jaffettwa lilna t-teptip?
1. Flicker affects workplace safety and productivity, comfortable living spaces, and according to recent research, our overall health and emotional well-being. For example, from a safety point of view, a fast rotating element present in the operator's field of view does not appear to be moving very fast, or stop due to excessive flickering. From a photobiological point of view, prolonged exposure to excessive flicker leads to neurological problems such as headaches, migraines, and even epilepsy.
2. Mil-lat tekniku, it-teptip jista 'jaffettwa bil-qawwa d-dawl għall-qbid ta' immaġni diġitali, speċjalment fi studios tat-TV u postijiet sportivi. Rekwiżiti stretti ta' xandir jirrikjedu l-użu ta' sistema ta' provvista ta' enerġija xierqa biex jiġu evitati artifatti tal-immaġni tal-kamera, speċjalment effetti stroboskopiċi waqt daqq bil-mod waqt qbid ta'-veloċità għolja.
3. Kif tillimita t-teptip?
1. F'sorsi ta 'dawl LED, it-teptip jista' jitnaqqas b'disinn xieraq u filtrazzjoni tal-provvista tal-enerġija, pereżempju bl-użu ta 'numru ogħla ta' capacitors. Alternattivament, jista 'jintuża konvertitur ta' vultaġġ ta 'frekwenza għolja. Bi dimmers LED, l-intensità tad-dawl tista 'tiġi aġġustata f'numru ta' modi. Il-bidla minn modulazzjoni tal-wisa 'tal-polz għar-regolamentazzjoni attwali, kif jagħmlu xi LCDs, inaqqas ukoll it-teptip.
2. Manufacturers use several different technical solutions to limit flicker. However, what is technically possible does not always translate into a perfect finished product. Changes in power system design can increase size and cost - not always an option for manufacturers. The result is a product on the market with flicker characteristics that don't match the customer's or designer's expectations. A device defined as having minimal flicker can actually be driven by high frequencies invisible to the human eye, not even a TV camera. Without proper measurements and standards, claims like "flicker free" can be more advertised than quantified properties.
Flicker is an old phenomenon that needs new consideration in the age of LED lighting. The industry has made progress in quantifying flicker and its measurement. Numerous industries and global standards organizations are in urgent need of further understanding and quantification of how flicker affects humans and other biological forms in multiple ways. In the meantime, progressive instrument makers such as GL Optic have developed methods to quantify certain flicker properties precisely and reproducibly. There is no doubt that the light is burning with positive outcomes for all when it comes to the future of addressing flickering.
