Analonsko zamenjavanje:<\/strong> Analonsko zamenjavanje prilagaja svetlost LED s spreminjanjem neprekinjenega toka, ki te\u010de skozi njo. Ta metoda vklju\u010duje zmanj\u0161anje toka za zmanj\u0161anje svetlosti ali pove\u010danje za pove\u010danje svetlosti. Analonsko zamenjavanje deluje tako, da prilagodi napetost prek LED ali uporabi oviro za omejitev toka, ki je v seriji z LED. S spreminjanjem upora ali ravnine napetosti se prilagodi tok, ki te\u010de skozi LED, kar povzro\u010di ustrezno spremembo svetlosti. Analonsko zamenjavanje zagotavlja gladko in neprekinjeno zamenjavanje brez vidnega utripanja.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-12799\" src=\"https:\/\/www2.iled-lights.com\/http:\/\/www2.iled-lights.com\/wp-content\/uploads\/2023\/08\/85-1024x563.jpg\" alt=\"Dimmbare LED\" width=\"1024\" height=\"563\" srcset=\"https:\/\/www.iled-lights.com\/wp-content\/uploads\/2023\/08\/85-1024x563.jpg 1024w, https:\/\/www.iled-lights.com\/wp-content\/uploads\/2023\/08\/85-1200x660.jpg 1200w, https:\/\/www.iled-lights.com\/wp-content\/uploads\/2023\/08\/85-300x165.jpg 300w, https:\/\/www.iled-lights.com\/wp-content\/uploads\/2023\/08\/85-768x422.jpg 768w, https:\/\/www.iled-lights.com\/wp-content\/uploads\/2023\/08\/85-1536x844.jpg 1536w, https:\/\/www.iled-lights.com\/wp-content\/uploads\/2023\/08\/85-18x10.jpg 18w, https:\/\/www.iled-lights.com\/wp-content\/uploads\/2023\/08\/85.jpg 2016w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<p><strong>2. Zamenjavanje z modulacijo \u0161irine impulza (PWM):<\/strong> Zamenjavanje PWM je digitalna tehnika zamenjavanja, ki LED hitro vklopi in izklopi pri visoki frekvenci. Raven svetlosti se nadzoruje s prilagajanjem razmerja med vklopljenim \u010dasom (de\u017ena cikel) in izklopljenim \u010dasom. Na primer, vi\u0161ji de\u017ena cikel (ve\u010d vklopljenega \u010dasa) povzro\u010di svetlej\u0161i izhod, medtem ko ni\u017eji de\u017ena cikel (ve\u010d izklopljenega \u010dasa) povzro\u010di temnej\u0161i izhod. Frekvenca preklopa je obi\u010dajno zelo visoka, pogosto v obmo\u010dju kilohertzov ali megahertzov, kar preide vklop\/izklop \u010duti \u010dlove\u0161ko oko. Zamenjavanje PWM se pogosto uporablja v LED sistemih za osvetlitev, ker je u\u010dinkovito in omogo\u010da natan\u010dno nadzorovanje ravni svetlosti. Vendar pa lahko nekateri opazijo utripanje pri nizkih ravneh zamenjavanja ali \u010de je PWM frekvenca pre nizka.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-12800\" src=\"https:\/\/www2.iled-lights.com\/http:\/\/www2.iled-lights.com\/wp-content\/uploads\/2023\/08\/86.jpg\" alt=\"Dimmbare LED\" width=\"804\" height=\"445\" srcset=\"https:\/\/www.iled-lights.com\/wp-content\/uploads\/2023\/08\/86.jpg 804w, https:\/\/www.iled-lights.com\/wp-content\/uploads\/2023\/08\/86-300x166.jpg 300w, https:\/\/www.iled-lights.com\/wp-content\/uploads\/2023\/08\/86-768x425.jpg 768w, https:\/\/www.iled-lights.com\/wp-content\/uploads\/2023\/08\/86-18x10.jpg 18w\" sizes=\"auto, (max-width: 804px) 100vw, 804px\" \/><\/p>","protected":false},"excerpt":{"rendered":"<p>White LEDs can be dimmed using two main methods: analog dimming and pulse-width modulation (PWM) dimming. 1.
