Uyu munsi, LED yerekana ikoreshwa cyane mubice bitandukanye, kandi igicucu cya LED irashobora kugaragara ahantu hose mumatangazo yo hanze yurukuta, ibibuga, stade, ibyiciro, hamwe numutekano. Nyamara, umwanda wumucyo uterwa numucyo mwinshi nabwo ni umutwe. Kubwibyo, nkuruganda rwa LED rwerekana nu mukoresha, ingamba zimwe na zimwe zigomba gufatwa kugirango dushyire mu gaciro ibipimo byerekana urumuri rwa LED no kurinda umutekano kugirango bigabanye ingaruka mbi ziterwa numucyo. Ibikurikira, reka twinjire mu myigire ya LED yerekana urumuri ubumenyi hamwe.
LED Yerekana Umucyo Urwego
Mubisanzwe, urumuri rwaLED yerekana imberebirasabwa kuba hafi 800-1200cd / m2, kandi nibyiza kutarenga iyi ntera. Umucyo urwego rwahanze LED yerekanani hafi 5000-6000cd / m2, bitagomba kuba byiza cyane, kandi hamwe na hamwe bimaze kwerekana hanze LED yerekana. Umucyo wa ecran ni muto. Kuri ecran ya ecran, ntabwo aribyiza guhindura urumuri hejuru rushoboka. Hagomba kubaho imipaka. Kurugero, urumuri ntarengwa rwo hanze ya LED yerekana ni 6500cd / m2, ariko ugomba guhindura urumuri kuri 7000cd / m2, rumaze kuba Niba rurenze urwego rushobora kwihanganira, ni nkubushobozi bwipine. Niba ipine ishobora kwishyurwa 240kpa gusa, ariko ukaba utinya ko umwuka uva cyangwa umuvuduko ukabije wumuyaga mugihe utwaye, ugomba kwishyuza 280kpa, noneho ushobora kuba waratwaye. Mugihe utwaye, ntacyo uzumva, ariko nyuma yo gutwara umwanya muremure, kubera ko amapine adashobora kwihanganira umuvuduko mwinshi wumuyaga, hashobora kubaho kunanirwa, kandi mubihe bikomeye, ikibazo cyo guturika amapine kirashobora kubaho.
Ingaruka mbi za LED Yerekana Ubwiza Bwinshi
Muri ubwo buryo bumwe, urumuri rwa LED rwerekana. Urashobora gushaka inama yuwakoze LED yerekana. Urashobora kwihanganira urumuri ntarengwa utagize ingaruka mbi kuri LED yerekana, hanyuma ukayihindura, ariko ntibisabwa uburyo urumuri ruri hejuru. Gusa uhindure uko hejuru, niba urumuri rwahinduwe hejuru cyane, bizagira ingaruka kubuzima bwa LED.
(1) Hindura ubuzima bwa serivisi ya LED yerekana
Kuberako urumuri rwa LED rwerekanwa rufitanye isano na diode ya LED, kandi umucyo wumubiri nigiciro cyo kurwanya diode washyizweho mbere yuko LED yerekana kuva muruganda, iyo rero urumuri ruri hejuru, ikigezweho cya diode ya LED nayo binini, kandi urumuri rwa LED narwo nabwo Bizakora mubihe nkibi birenze urugero, kandi nibikomeza gutya, bizihutisha ubuzima bwumurimo wamatara ya LED no kwiyegereza urumuri.
(2) Gukoresha ingufu zo hanze LED yerekana
Iyo urumuri rwinshi rwa LED rwerekana ecran, niko module igezweho, bityo imbaraga za ecran zose nazo nini, kandi gukoresha ingufu nabyo ni byinshi. Isaha, 1 kWh y'amashanyarazi ni 1.5 Yuan, kandi niba ibarwa iminsi 30 mukwezi, noneho fagitire yumuriro yumwaka ni: 1.5 * 10 * 1.5 * 30 * 12 = 8100; niba ibarwa ukurikije ingufu zisanzwe, niba buri saha 1.2 kWh y'amashanyarazi, noneho fagitire y'amashanyarazi yumwaka ni 1.2 * 10 * 1.5 * 30 * 12 = 6480. Ugereranije byombi, biragaragara ko iyambere ari uguta amashanyarazi.
(3) Kwangirika kw'ijisho ry'umuntu
Umucyo w'izuba ku manywa ni 2000cd. Mubisanzwe, umucyo wo hanze LED yerekana uri muri 5000cd. Niba irenze 5000cd, yitwa kwanduza urumuri, kandi bizangiza cyane abantu. Cyane cyane nijoro, urumuri rwo kwerekana ni runini cyane, ruzamura amaso. Ijisho ryumuntu rituma ijisho ryumuntu ridashobora gukingurwa. Nkuko nijoro, ibidukikije bigukikije byijimye cyane, kandi umuntu ahita amurikira itara kumaso yawe, kuburyo amaso yawe atazashobora gukingura, noneho, LED yerekana ihwanye nigitara, niba utwaye, hanyuma hari impanuka zo mumuhanda zishobora kubaho.
LED Yerekana Ubwiza Gushiraho no Kurinda
1. Hindura umucyo wo hanze LED yuzuye yerekana amabara ukurikije ibidukikije. Intego nyamukuru yo guhindura umucyo ni uguhindura urumuri rwa ecran ya LED yose ukurikije ubukana bwurumuri rwibidukikije, kuburyo rusa neza kandi rwerurutse ntiruba ruteye ubwoba. Kuberako ikigereranyo cyumucyo wumunsi wumucyo numucyo wijimye wumunsi wizuba gishobora kugera 30.000 kugeza kuri 1. Igenamiterere rihuye naryo riratandukanye cyane. Ariko kuri ubu nta bikoresho byo kumurika byihariye. Kubwibyo, uyikoresha agomba guhindura urumuri rwa LED yerekana mugihe gikurikije impinduka mubidukikije.
2. Shyira ahagaragara ubururu busohoka hanze LED yuzuye-amabara yerekana. Kuberako umucyo ari ikintu gishingiye kumyumvire iranga ijisho ryumuntu, ijisho ryumuntu rifite ubushobozi butandukanye bwo kumva urumuri rwuburebure butandukanye, bityo umucyo gusa ntushobora kwerekana neza ubukana bwurumuri, ariko gukoresha imishwarara nkigipimo cyingufu zumutekano zigaragara urumuri rushobora kwerekana neza Igipimo cyumucyo kigira ingaruka kumaso. Agaciro ko gupima ibikoresho bipima imishwarara, aho kugira ngo ijisho ryumucyo wumucyo wubururu bwubururu, bigomba gukoreshwa nkibanze kugirango harebwe niba ubukana bwurumuri rwubururu bwangiza ijisho. Hanze ya LED yerekana abayikora nabayikoresha bagomba kugabanya urumuri rwubururu rusohoka rwerekana LED mugihe cyo kwerekana.
3. Gereranya urumuri rwo gukwirakwiza nicyerekezo cya LED yuzuye-amabara yerekana. Abakoresha bagomba kugerageza uko bashoboye kugirango basuzume gushyira mu gaciro gukwirakwiza urumuri rwa LED rwerekana amashanyarazi, kugirango ingufu z'umucyo zitangwa na LED zigabanwe mu byerekezo byose murwego rwo kureba, kugirango birinde urumuri rukomeye rwa ruto kureba inguni LED ikubita ijisho ryumuntu. Muri icyo gihe, icyerekezo n’urumuri rwa LED yumucyo bigomba kugarukira kugabanya umwanda w’urumuri rwa LED ku bidukikije.
4. Shyira ahagaragara ibisohoka inshuro yuzuye ya ecran ya ecran. LED yerekana ibicuruzwa igomba gushushanya ibyerekanwa bikurikije ibisabwa, kandi ibisohoka inshuro ya ecran yerekana bigomba kuba byujuje ibisabwa kugirango birinde kwirinda kubireba bitewe no guhindagurika kwa ecran.
5. Ingamba zumutekano zavuzwe neza mubitabo byabakoresha. Uruganda rwa LED rwerekana rugomba kwerekana ibyitonderwa mumfashanyigisho yumukoresha wa LED, rugasobanura uburyo bukwiye bwo guhindura imiterere yumucyo wuzuye wa ecran yuzuye, hamwe nibishobora kwangiriza ijisho ryumuntu biterwa no kureba neza LED igihe kirekire. . Mugihe ibikoresho byoguhindura urumuri byananiranye, bigomba gukoreshwa cyangwa guhinduranya LED bigomba kuzimwa. Mugihe uhuye nicyerekezo gitangaje cya LED ahantu hijimye, ingamba zo kwikingira zigomba kuba, ntukarebe neza ibyerekanwa bya elegitoronike LED igihe kinini cyangwa ngo umenye neza amashusho yerekana amashusho kuri LED yerekana, hanyuma ugerageze kwirinda LED kwibanda ku jisho. Ahantu heza haratwika retina.
6. Ingamba zo gukingira zifatwa mugihe cyo gushushanya no gukora LED yuzuye ibara ryerekana. Abashinzwe gushushanya no kubyaza umusaruro bazahura na LED yerekanwe kenshi kurenza abakoresha. Mugushushanya no kubyaza umusaruro, birakenewe kugerageza imikorere yikirenga ya LED. Kubwibyo, abashushanya n'abakozi bashinzwe kubyara bahura n’umucyo ukomeye wa LED bagomba kwitondera cyane no gufata ingamba zidasanzwe zo kurinda mugushushanya no gutunganya umusaruro wa LED. Mugihe cyo gukora no kugerageza hanze-yaka cyane LED yerekana, abakozi bireba bagomba kwambara amadarubindi yizuba yumukara hamwe numucyo wikubye inshuro 4-8, kugirango babashe kureba ibisobanuro birambuye byerekana LED hafi. Mubikorwa byo kwerekana LED mu nzu kwerekana umusaruro no kugerageza, abakozi bireba bagomba kwambara amadarubindi yumukara hamwe numucyo wikubye inshuro 2-4. Cyane cyane abakozi bapima LED yerekana ahantu hijimye bagomba kwita cyane kurinda umutekano. Bagomba kwambara amadarubindi yizuba mbere yo kureba neza.
Nigute LED Yerekana Ababikora Bakorana Nubwiza Bwerekana?
(1) Hindura amasaro
Urebye ingaruka mbi ziterwa no kumurika kwinshi kwerekanwa rya LED, igisubizo cya LED yerekana uruganda ni ugusimbuza amasaro asanzwe yamatara namasaro yamatara ashobora gushyigikira ecran-yerekana cyane, nka: Itara rya Nation Star rifite urumuri rwinshi SMD3535 amasaro. Chip yasimbujwe chip ishobora gushyigikira umucyo, bityo umucyo urashobora kwiyongera kuri cd magana kugeza kuri cd 1.000.
(2) Hindura mu buryo bwikora umucyo
Kugeza ubu, ikarita rusange yo kugenzura irashobora guhindura urumuri buri gihe, kandi amakarita amwe amwe arashobora kongeramo fotorezistor kugirango ahite ahindura urumuri. Ukoresheje ikarita yo kugenzura LED, uruganda rwerekana LED rukoresha sensor yumucyo kugirango ipime urumuri rwibidukikije, hamwe nimpinduka ukurikije amakuru yapimwe. Ihindurwamo ibimenyetso byamashanyarazi hanyuma ikoherezwa kuri microcomputer imwe-chip, microcomputer imwe imwe noneho itunganya ibyo bimenyetso, hanyuma imaze kuyitunganya, igenzura inzinguzingo yumusoro wibisohoka PWM kumurongo runaka. Umuvuduko wa LED yerekana ecran ihindurwa na switch voltage igenzura uruziga, kugirango urumuri rwa ecran ya LED yerekanwe ihita igenzurwa, bityo bikagabanya cyane kwivanga kwurumuri rwa ecran ya LED kubantu.
