Chii chinonzi LED? Inopenya zvinhu zvaunotenga nguva dzose
Ma LED ari pose pose; pane kunyange mukana wakanaka wekuti uri kuverenga nyaya ino pamusoro pe LED pane chiedza chinobva kune rimwe kana kupfuura ma LED. Saka, chii chinonzi heck LED? Iwe uri kuda kuziva.
LED Tsanangudzo
LED inomirira Light-Emitting Diode, imwe yechirongwa chemagetsi yakagadzirwa nemhando mbiri dzakasiyana semiconductor . Saizvozvowo mune pfungwa kune semiconductor zvinhu zvinoshandiswa mune zvakasiyana-siyana zvemakombiyuta, zvakadai seB RAM , zvinogadziridza, uye zvigadzirisiti, diode ndiyo majaira anobvumira kupera kwemagetsi kuitika nenzira imwe chete.
Chiedza chetambo chinoita chinhu chimwechete: Inodzivisa kutenderera kwemagetsi mune imwe nzira apo uchiita kuti iende mberi pachena mune imwe. Apo magetsi mune maitiro e electroni anotenderera nepakati pepakati pakati pemarudzi maviri e semiconductor zvinhu, simba rinopihwa nenzira yechiedza.
LED History
Chikwata chekutanga che LED ndecheOleg Losev, muumbi weRussia uyo akaratidza LED muna 1927. Zvakatora anenge makore makumi mana isati yasikwa yakashandiswa kushandiswa, zvisinei.
Ma LED anotanga kuonekwa muzvigadzirwa zvemabhizimisi muna 1962, apo Texas Instruments yakaita kuti iwanike LED yakapa chiedza mumhepo inonzi infrared spectrum. Aya mavhesi ekutanga aishandiswa zvikuru mumagetsi ekudzivirira, zvakadai sekutanga kweterevhizheni .
Chiedza chekutanga chechiedza chakaonekwa chakaitawo kuti chivepo muna 1962, ichibudisa chimwe chinhu chisina simba asi chinoratidzika chiedza chakachena. Imwe gumi yemakore yaizopfuura kupenya kwaisazowedzerwa, uye mamwe mavara, zvikuru-mavara uye machena-machena-orange, akawanikwa.
Ma LED akabuda muna 1976 nekuiswa kwekukwirira-mhanya uye yakanakisisa-yemaenzaniso inogona kushandiswa mumhando dzakasiyana-siyana dzekushanda, kusanganisira kutaurirana uye sezviratidzo mu instrumentation. Pakupedzisira, ma LED aishandiswa mu calcul calculators as numeric displays.
Bhuruu, Tsvuku, Tsvuku, Tsvuku-Orange neGreen LED Chiedza Chivara
Ma LED mumakore makumi manomwe ekupedzisira uye ekutanga kwema80s akanga akangosara kumavara mashoma chete; tsvuku, tsvuku, tsvuku-machena, uye ruvara ndiwo mavara akakurumbira anowanikwa. Kunyange zvazvo zvaive zvichibvira mubazi kuti ibudise ma LED ane mavara akasiyana-siyana, mutengo wekugadzirwa wakaramba uchiwedzera ku-LED mararamiro kubva kune kuwanda-kwakagadzirwa.
Zvaifungidzirwa kuti LED inobereka chiedza mumucheka webhuruu yaizobvumira LED kuti dzishandiswe muzere mavara mavara. Tsvakurudzo yaive yekutengeserana kwebhuruu LED, iyo, iyo inosanganiswa neIt LED dzvuku uye dzemaodzanyemba, dzaigona kubudisa mavara akawanda. Yokutanga-kupenya kwebhuruu LED yakatanga kutanga muna 1994. High-simba uye yakakwirira-inobudirira bluu LED yakabuda makore mashoma gare gare.
Asi pfungwa yekushandisa LED dzehuwandu hwakazara hauna kumbove yakanyanya kure kusvikira kushandiswa kweM LED yakachena, iyo yakaitika nguva pfupi mushure mekukwirira kwepamusoro-soro kweTV LED.
Kunyangwe iwe uchiona izwi rokuti LED TV kana kutarisa kwe LED, dzakawanda zvemarudzi aya ekuratidzira dzinoshandisa LCD (Liquid Crystal Display) yehutarisiro chaihwo, uye kushandisa LED kuti zvijekese LCDs . Izvozvo hazvirevi kuti chokwadi che-LED-based display hachina kuwanikwa mumagetsi uye maTV achishandisa OLED (Organic LED) teknolojia ; vanongotarisa kutengesa uye kuoma kugadzira zviyero zvakakura. Asi sezvo nzira yekugadzira ichiri kuramba ichikura, ndizvo zvinoita kuti chiedza che LED chive chichikura.
Zvishandiswa zve LED
Tendekiti yeTV inoenderera mberi ichikura uye kushandiswa kwakasiyana-siyana kwema LED kwave kuwanikwa, kusanganisira:
- Infrared LEDs inoshandiswa pakuchengetedza midziyo. Tarisa kuti TV iri kure; mukana kune pane LED inotengeswa pamabhizimisi ekupedzisira kwemahombekombe.
- LED dzinoshandiswa sechiedza chekuisa mukati mezvigadzirwa nemagetsi. Pane imwe nguva, neon uye magetsi ekudzivirira aigara achishandiswa. Iye zvino ma LED, ayo anoshanda zvakanyanya, ane hupenyu hurefu, uye anowanzosvitsa mari, atora kushandiswa uku.
- LED dzinoshandiswa mukuratidzira, kusanganisira alphanumeric zviratidzo zvinowanikwa muzvinhu zvose kubva pamavambo okutanga kusvika kumaawa, zviratidzo zvekutengeserana, uye kutakura mafirimu. Uye usakanganwa kuti zvichida TV yako nekombiyuta rinotarisa zvinoshandisa ma LED kuti zvivhenekera kuratidzwa.
- Uye zvechokwadi, hatigone kukanganwa kujekesa; Ma LED ari nani munzira yavo yokugadzirisa zvachose iyo incandescent light bulbs yakagadziriswa naTommas Edison. Pamwe munzira, fluorescents mumisha uye nzvimbo dzebhizimisi dziri kuonawo zvishoma kushandiswa.
Ma LED achaenderera mberi achishandiswa mune zvakasiyana-siyana zvemishonga, uye kushandiswa kutsva kuri kubviswa nguva yose.
