Inganda za LED zerekana iterambere ryinshi kandi ubu zifatwa nkimwe mu nzego zikomeye kandi zitanga isoko ku isi. LED yamashanyarazi nibintu byingenzi muriLEDbigira uruhare runini mukwemeza ubuziranenge bwerekana. Kugirango usobanukirwe neza amasaro ya LED, ni ngombwa gusuzuma imibare muruganda.
Ingano y’isoko ku isi y’amatara ya LED biteganijwe ko iziyongera 9,6%, ikagera kuri miliyoni 240.9 USD muri 2028, ikava ku rwego rwa 2022. Iri terambere rikomeye ryerekana uruhare rukomeye ayo masaro yamatara agira muruganda rwa LED.
Niba uteganya gushora imari muri LED, gusobanukirwa amatara ya LED nibyingenzi. Witondere kandi gushakisha ubwoko butandukanye bwamasaro ya LED aboneka.
Amasaro ya LED ni iki?
Gusobanukirwa nubusobanuro bwamasaro yamatara nintambwe yambere yo kumenya uruhare ibyo bice bigira muri ecran ya LED. Amatara ya LED, azwi kandi nka LED chip cyangwa emitter, ni mato mato mato matoLED ibicuruzwanka LED yerekana. Iyi semiconductor ituma LED itanga urumuri kandi mubisanzwe bikozwe mubikoresho nka:
- Arsenic
- Galiyumu
- Fosifore
Ibara ryasohowe na LED biterwa nibikoresho bikoreshwa muri semiconductor. Amabara asanzwe arimo umutuku, umuhondo, icyatsi, n'ubururu. Aya masaro ya LED nurufunguzo rwimikorere ya LED ikora cyane. Ziza muburyo butandukanye, nka:
- Urukiramende
- Umwanya
- Uruziga
- Kuruhande
- Micro
- Ubuso
Buri saro ryamatara rifite amasano abiri ahuye nibyiza nibibi muri semiconductor. Anode itwara ibintu byiza, mugihe cathode itwara amafaranga mabi. Urashobora kumenya byoroshye ibi (+) na (-) ibimenyetso byashyizweho kashe.
Ubwoko bwa LED Uburyo bwo Gutunganya Amasaro
Amatara ya LED atunganyirizwa muburyo butandukanye, bushobora guhindura imikorere yabo nintererano yubwiza bwa LED. Mubisanzwe, basizwe hamwe na diffuzeri cyangwa lens, bituma igice cya kabiri cyogukurikirana kugenzura ibintu nkuburemere nicyerekezo cyumucyo. Amashanyarazi ya LED ubusanzwe ashyirwa kuri aPCB (Icapa ryumuzingo wacapwe).
Uburyo bukoreshwa cyane bwa LED bwo gutunganya amasaro ni DIP (Direct In-line Package),SMD (Ubuso-bushiraho Diode), naCOB (Chip On Board). Buri buryo bufite inyungu zabwo muburyo bwo gukora, igiciro, no gushyira mubikorwa.
DIP (Ububiko butaziguye)
Amatara ya LED akoreshwa muburyo bwa DIP agenda agaragara cyane ku isoko no mu nganda za LED. Nyamara, baracyatanga ibyiza byinshi nibiranga:
- Nibyiza byo gukoresha hanze
- Umucyo mwinshi
- Guhagarara neza
- Ingero ntoya yo kureba (H / V 120/60 dogere)
SMD (Ubuso-bushiraho Diode)
Uburyo bwo gutunganya SMD nuburyo bukunzwe cyane muburyo bwose bwamatara ya LED, cyane cyane mubikorwa byo kwerekana LED. Bimwe mubiranga SMDs harimo:
- Gutunganya byoroshye kandi byoroshye
- Igiciro cyiza
- Inguni yo kureba (H / V 120/120 dogere)
- Kuboneka mubunini
COB (Chip On Board)
Ubwanyuma, Chip On Board (COB) bivuga uburyo bwo gutunganya aho amasaro ya LED yamashanyarazi ashyirwa kumurongo wumuzunguruko, bitandukanye nuburyo busanzwe aho ibyuma bya LED bishyirwa kumurongo. Ubu buryo buzwi kuri ibi bikurikira:
- Glop-top alias
- Gukwirakwiza neza chip
- Kurinda amasano yayo
Ibiranga amasaro ya LED
Iyo usobanukiwe n'amatara ya LED, hari ibintu bimwe na bimwe bikunze kugaragara:
- Gutondekanya umurongo
- Umucyo woroshye (munsi ya mg 1 kuri LED)
- Ubuso butunganijwe
- Umucyo woroshye
- RGB ipakira
LED Amatara yamashanyarazi na LED (Diode itanga urumuri)
LED yamatara hamwe na diode itanga urumuri (LED) bifitanye isano ariko ibice bitandukanye, hamwe nibintu bimwe bisangiwe nibitandukaniro byingenzi. Dore kugereranya ibiranga:
| Ibiranga | LED Amatara | Diode itanga urumuri (LED) |
|---|---|---|
| Amashanyarazi | Yego | Yego |
| Kwishyuza | Ibyiza | Ibyiza |
| Umuvuduko | Gusubira inyuma | Gusubira inyuma |
| Kumurika | Gukora neza cyane | Gukora neza |
| Amashanyarazi | Birenzeho Ibiriho | Ntibyoroshye kubyubu |
| Ubwoko bwo Kwinjiza | SMD | Gucomeka |
Ibyiza byo gukoresha LED Itara
Amatara ya LED akoreshwa muburyo bwa LED kubera inyungu nyinshi batanga. Hano hari bimwe mubyiza ushobora kwitega.
Umwanya muto
Amatara ya LED akoreshwa cyane muri micro-intera ya LED itera ibice, cyane cyane kubyerekanwa bisaba urumuri rwinshi kandi rukora neza. Aya masaro amaze kwamamara kuri micro-spacingecran ya LED.
Guhoraho
Amatara ya LED atanga urumuri ruhoraho, uburinganire bwera, nurwego rwa chromaticity. Bitandukanye na LED zimwe na zimwe zishobora kwerekana urumuri rutandukanye uhereye ku mpande zitandukanye, izo zikoreshwa namasaro yamatara zigumana uburinganire murwego rwo kwerekana.
Kureba Inguni-Biterwa
Muguhitamo amatara ya LED, impande zo kureba ni ikintu cyingenzi.Hanze LED yerekanaUkeneye impande nini zo kureba, bityo amasaro agomba gutanga urumuri rwuzuye kugirango ahuze iki gisabwa.
Ingano
Ingano yerekana LED yerekanwa no gukoresha amasaro. Birakwiriye cyane cyane kuri ecran ntoya, murugo, bigatuma biba byiza kubisaba bisaba kwerekana neza kandi neza.
Ubuzima
LED yerekana ukoresheje amasaro yamatara yagenewe kumara igihe kirekire kurenza ayandi moko ya semiconductor. Izi ecran zirashobora kumara amasaha 100.000, zitanga igihe kirekire nimbaraga bitewe nubushyuhe bukomeye bwa PCB.
Igipimo cyo kunanirwa
Igipimo cyo kunanirwa muri LED yerekana namasaro yamatara biragaragara. Inenge imwe muri pigiseli ibihumbi (umutuku, icyatsi, ubururu) irashobora guhagarika imikorere ya ecran muri rusange, ariko amasaro yamatara agabanya cyane ibyago.
Ubushobozi bwo Kurwanya
LED yamatara azwiho kurwanya anti-static. Kubera ko diode itanga urumuri rwumva cyane amashanyarazi ahamye, birashoboka kunanirwa. Nyamara, amasaro yamatara arwanya static bigabanya amahirwe yo kunanirwa guterwa na ecran ya LED.
Nigute washyira amatara ya LED
Mugihe ushyira amatara ya LED, ni ngombwa gukurikiza intambwe nziza. Urashobora kwishingikiriza kubanyamwuga mugushiraho, ariko niba uhisemo kubikora wenyine, dore ubuyobozi bworoshye:
- Menya ubwoko bwamatara ya LED uburyo bwo gutunganya amasaro yakoreshejwe.
- Suzuma insinga enye zashyizwe mumatara yubwoko bwa LED.
- Shyira akamenyetso k'ingenzi ku nsinga (mubisanzwe kuri metero) hanyuma ugabanye witonze ahabigenewe (Ubundi, urashobora gusaba amasaro yabanje kugabanywa kubitanga mbere yo kubyara).
- Kugenzura icomeka hanyuma ukureho igifuniko cya plastike mumacomeka.
- Huza itara ryikizamini, ariko wirinde kubipfukirana cyangwa kubihuza neza nigifuniko.
- Tangira kwishyiriraho neza kugirango ubone itara.
- Witonze ushyireho itara rya SMD LED ukoresheje umurizo na clip.
Uburyo bwo Guhitamo Amashanyarazi meza ya LED
Guhitamo amashanyarazi meza ya LED bikubiyemo gusuzuma ibintu byinshi byingenzi bishobora kumenya niba uzanyurwa nicyemezo cyawe cyangwa ukicuza. Kugirango urangize urangije imikorere kandi yujuje ubuziranenge LED yerekana, dore inama zingenzi:
- Witondere cyane ingingo zigurishwa.
- Hitamo chip ihamye kugirango yemeze ecran ya LED nziza.
- Menya neza ko ubuso bwa LED bufite isuku, butarimo ikizinga, nibindi byanduye.
- Reba ubwiza bwa kole ikoreshwa mumasaro yamatara uyakanda witonze (kole yo mu rwego rwo hasi irashobora gutera gucika cyangwa guhindura).
- Tekinoroji yo gupakira igira uruhare runini mumikorere yamatara yawe ya LED hamwe na disikuru bakora.
- Gura ibicuruzwa gusa kubitanga byizewe kandi byizewe.
Umwanzuro
Gusobanukirwa amatara ya LED birashobora gusa nkibikabije, ariko kumenya ibice byerekana LED yawe birashobora kugufasha guhitamo ecran nziza kandi ugakoresha neza ubushobozi bwabo. Aya masaro ahujwe cyane na LED, ariko ntabwo ari diode ubwayo. Nibice bya semiconductor bitanga ecran ya LED yose kandi igafasha diode gusohora urumuri.
Niba utazi neza kwibira mumasaro ya LED, nibyiza rwose. Gusa menya neza ko ufite ubumenyi bwibanze kuri bo, mugihe rero igihe cyo guhitamo LED yerekana, urashobora gupima ibyiza nibibi byabo.
