Kuki amatara ya LED ari ingenzi cyane kwerekana LED?

1. Kureba Inguni

Inguni yo kureba ya LED yerekanwe biterwa no kureba impande zamatara ya LED. Kugeza ubu, benshihanze LED yerekananaLED yerekana imbere koresha LED LEDs hamwe na horizontal na vertical kureba inguni ya 140 °. Inyubako ndende LED yerekana bisaba guhagarara hejuru. Inguni yo kureba no kumurika biravuguruzanya, kandi impande nini yo kureba byanze bikunze igabanya umucyo. Guhitamo kureba inguni bigomba kugenwa ukurikije imikoreshereze yihariye.

Ubucyo

Umucyo w'itara rya LED ni urumuri rukomeye rugaragaza urumuri rwa LED. Iyo urumuri rwinshi rwa LED, niko urwego rwinshi rukoreshwa, arirwo rwiza rwo kuzigama ingufu no gukomeza LED itajegajega. LED ifite inguni zitandukanye. Iyo umucyo wa chip ukosowe, ntoya inguni, urumuri rwa LED, ariko ruto ruto rwo kureba. Mubisanzwe, dogere 120 ya LED igomba gutoranywa kugirango irebe neza impande zerekana. Kugaragaza hamwe nududomo dutandukanye hamwe nintera itandukanye yo kureba, impirimbanyi igomba kuboneka mumucyo, inguni nigiciro.

3. Igipimo cyo kunanirwa

Kuvaibara ryuzuye LED kwerekana igizwe n'ibihumbi mirongo cyangwa ndetse n'ibihumbi magana ya pigiseli igizwe na LED itukura, icyatsi n'ubururu, kunanirwa kw'ibara iryo ari ryo ryose LED bizagira ingaruka rusange muri rusange yerekana LED yose. Muri rusange, ibipimo byo kunanirwa kwerekanwa LED ntibigomba kuba hejuru ya 3/000 mbere yuko LED yerekana itangira guterana no gusaza amasaha 72 mbere yo koherezwa.

4. Ubushobozi bwo kurwanya

LED ni igikoresho cya semiconductor, cyumva amashanyarazi ahamye kandi gishobora kuganisha byoroshye kumashanyarazi. Kubwibyo, ubushobozi bwo kurwanya-static ni ngombwa cyane mubuzima bwa ecran ya ecran. Muri rusange, imbaraga zananiranye za LED yumubiri wumuntu electrostatike ntabwo igomba kuba munsi ya 2000V.

5. Guhoraho

Ibara ryuzuye LED yerekana ecran igizwe na pigiseli igizwe na LED nyinshi zitukura, icyatsi, n'ubururu. Ihuzagurika ryumucyo nuburebure bwa buri bara LED igena umucyo uhoraho, uburinganire bwera, hamwe na chromaticité ya ecran yose yerekana.

Ibara ryuzuye LED yerekana ifite icyerekezo, ni ukuvuga, umucyo wacyo uziyongera cyangwa ugabanuke iyo urebye uhereye kumpande zitandukanye. Muri ubu buryo, guhuza inguni ya LED itukura, icyatsi, nubururu bizagira ingaruka zikomeye ku guhuza uburinganire bwera ku mpande zitandukanye, kandi bigira ingaruka ku budahemuka bwibara rya videwo ryerekanwa. Kugirango ugere kumurongo uhuza urumuri rwumutuku, icyatsi nubururu LEDs kumpande zitandukanye, birakenewe ko dukora ubushakashatsi bwa siyanse mugushushanya ibyuma bipakira no gutoranya ibikoresho fatizo, biterwa nurwego rwa tekiniki rwa utanga ibicuruzwa. Nuburyo bwiza icyerekezo gisanzwe cyera kiringaniye, niba LED inguni idahwitse itari nziza, impuzandengo yera yinguni zinguni zitandukanye za ecran yose izaba mbi.

6. Ibiranga Attenuation

Nyuma yo kwerekana LED ikora igihe kirekire, umucyo uzagabanuka kandi ibara ryerekana ntirishobora guhuzagurika, ibyo bikaba biterwa ahanini nubwinshi bwimikorere yibikoresho bya LED. Kwiyegereza urumuri rwa LED bizagabanya umucyo wa ecran ya LED yose. Kudahuza urumuri rwinshi rwa LED itukura, icyatsi nubururu bizatera guhuza ibara ryibara rya LED. Amatara maremare ya LED arashobora kugenzura neza ubunini bwurumuri. Ukurikije igipimo cya 20mA kimurika ku bushyuhe bwicyumba cyamasaha 1000, umutuku ugomba kuba munsi ya 2%, naho ubururu nicyatsi kibisi bitarenze 10%. Noneho, gerageza kudakoresha 20mA ikigezweho kubururu nicyatsi kibisi LED mugushushanya, kandi nibyiza gukoresha 70% kugeza 80% gusa byumuvuduko.

Usibye ibiranga attenuation ijyanye nibiranga LED itukura, icyatsi nubururu ubwayo, ikoreshwa ubu, igishushanyo mbonera cyo gukwirakwiza ubushyuhe bwa PCB, hamwe nubushyuhe bwibidukikije bwa ecran yerekana byose bigira ingaruka kuri attenuation.

7. Ingano

Ingano yigikoresho cya LED igira ingaruka kuri pigiseli intera yerekana LED, ni ukuvuga imyanzuro. Andika SMD3535 LED ikoreshwa cyane cyaneP6, P8, P10 hanze LED yerekana, SMD2121 LED ikoreshwa cyane cyaneP2.5,P2.6,P2.97,P3.91 ecran mu nzu . Hashingiwe ko ikibanza cya pigiseli kidahindutse, ubunini bwamatara ya LED bwiyongera, bushobora kongera aho bugaragarira no kugabanya ingano. Ariko, kubera kugabanuka kwahantu hirabura, itandukaniro rizagabanuka. Ibinyuranye, ubunini bwa LED buragabanuka,bigabanya ahantu herekana kandi byongera ingano, agace kirabura kiyongera, kongerera igipimo.

8. Ubuzima

Igihe cyo kubaho cyamatara ya LED ni amasaha 100.000, kikaba kirekire cyane kuruta ibindi bice bigize LED yerekana igihe cyo kubaho. Kubwibyo, mugihe cyose ubwiza bwamatara ya LED bwizewe, amashanyarazi akora arakwiriye, igishushanyo mbonera cyo gukwirakwiza ubushyuhe bwa PCB kirumvikana, kandi uburyo bwo kwerekana ibyerekanwe birakomeye, amatara ya LED azaba ibice biramba kurukuta rwa videwo ya LED.

LED modules ibarirwa kuri 70% yikiguzi cya LED yerekana, bityo LED modules irashobora kumenya ubwiza bwa LED yerekanwe. Ikoranabuhanga rihanitse risabwa LED yerekana ecran nicyerekezo cyiterambere. Kuva kugenzura modules ya LED, kugirango duteze imbere Ubushinwa kuva mubihugu binini byerekana LED bikagera mu gihugu gikomeye cyerekana LED.
