Kodi Ma LED Opanda AC Amakhala Otani?

Tekinoloje yowunikira ya LED ikukula mwachangu kwambiri. Imatchuka ndi anthu pakupulumutsa mphamvu kwambiri, kuteteza zachilengedwe zobiriwira, komanso moyo wautali. Ukadaulo watsopano ndi mayankho atsopano pakugwiritsa ntchito apezekanso. Mapangidwe owunikira a LED amatha kuphatikiza mawonekedwe a magwero a kuwala, monga magwero a kuwala, magwero ozizira ozizira, ndi kusintha kwa mitundu, ndi zina zotero, ndithudi adzakhala gawo lalikulu la msika wowunikira. M'zaka zaposachedwa, ndi kuwongolera kosalekeza kwa kafukufuku wa LED pankhani yosankha zinthu komanso ukadaulo wopanga mamangidwe, ukadaulo watsopano wa AC Light -emitting diode AC -free LED idayamba. Kudzera mu lingaliro latsopano, idalimbikitsa ukadaulo wowunikira wa LED Practical. LED yopanda AC imagwirizana ndi chikhalidwe cha DCLED. Sichiyenera kudutsa kutembenuka kwa AC/DC, komwe kumatha kulumikizidwa mwachindunji muukadaulo wowunikira wa LED womwe umagwiritsidwa ntchito mu 220V (kapena 110V). Chinsinsi cha ukadaulo wa AC wopanda ukadaulo wa LED ndikukonza kwapadera ndi kuphatikiza kwa njere za LED pakuyika. Nthawi yomweyo, mawonekedwe a diode a mfundo ya LEDPN amakonzedwanso. Kupyolera mu semiconductor kupanga ndondomeko Crystal luso, ndi kutengera staggered masanjidwewo makonzedwe ndondomeko kupanga dera mlatho, kuti AC panopa akhoza anatsegula mu njira ziwiri, ndi emitting kuwala. Kapangidwe ka mbewu ndi AC driver wopanda njere za LED pogwiritsa ntchito chojambula chokhazikika cha matrix. Kwenikweni AC -free LED njere makonzedwe chithunzi, AC -free LED mbewu njere kuti kuwala pambuyo kulumikiza kulankhulana, kotero awiri okha otsogola chofunika Import ndi kulankhulana gwero akhoza chowala ntchito. Mfundo yogwirira ntchito ya gwero la kuwala kwa AC -free LED imapangidwa ndi njira yokhazikika ya matrix ndi ma microlymation a LED. Njere, theka labwino -pamzere weniweni wa kulumikizana, njere za LED za mkono wa mlatho wa 3 zimawala, theka loyipa -pamzere wa madontho, ndi njere za LED zokhala ndi manja a mlatho wa 3 zikuwala. Kuwala, poyerekeza ndi njere za LED pa mkono wa mlatho nthawi yomweyo, ndi njere za LED pa mkono wapakati pa mlatho zakhala zikuwala chifukwa cha kugawana. AC -free LED ndi yaying'ono ndipo nthawi zambiri imagwiritsidwa ntchito pazowonetsa zamakampani ndi anthu wamba; high -voltage ndi otsika -current in -zakuya ubwino amagonjetsa vuto la kutaya kwambiri kwa mzere pogwiritsa ntchito DCLED, zomwe zimadalira kupitiriza kwa magetsi a magetsi; Kuwala kwa LED kosawonongeka kwa ESD vuto; gwiritsani ntchito ukadaulo wa micro-grain kuti muwongolere bwino kuyatsa; chifukwa cha kusintha kwa mphamvu yamagetsi komanso kuwongolera kwaposachedwa, kwamakampani opanga zowunikira komanso makampani opanga ma backlight a LCD, ndiukadaulo watsopano. Pakalipano, AC -free LED ikusinthidwabe mosalekeza ponena za kuwala kowala, mphamvu, ndi zina zotero, koma kupeza kwa ma LED opanda AC ndi ophweka komanso otsika mtengo, apamwamba kwambiri. Satifiketi yaukadaulo ya AC yaulere ya LED ikukula. Amakhulupirira kuti posachedwapa, zinthu zowala kwambiri, zamphamvu kwambiri, komanso zotsika mtengo zidzapezeka zambiri.
