Sechishandiso chakakosha chekuvhenekesa pakutyaira husiku, marambi emota ari kuwedzera kutariswa sechigadzirwa chinofarirwa nevagadziri vemota vakawanda nekuenderera mberi kwehunyanzvi hwe LED. Mwenje yemotokari ye LED inoreva marambi anoshandisa tekinoroji yeLED senzvimbo yekuvhenekesa mukati nekunze kwemotokari. Midziyo yekuvhenekesa yekunze inosanganisira akawanda akaomesesa zviyero senge thermal muganho, electromagnetic kuenderana (EMC), uye mutoro wekuyedza kuyerwa. Aya marambi emotokari ye LED haangonatsiridza mwenje wemotokari, asi zvakare anogadzira nzvimbo yakagadzikana yemukati.

Kugadzirwa kwemwenje we LED
Izvo zvakakosha zve LED zvinosanganisira waya yegoridhe, LED chip, inopenya mhete, cathode waya, plastiki waya, uye anode waya.
Chikamu chakakosha che LED ndiyo chip inoumbwa nep-mhando semiconductor uye n-mhando semiconductor, uye chimiro chakaumbwa pakati pavo chinonzi pn junction. Muchikamu chePN chezvimwe zvinhu zve semiconductor, apo nhamba shomanana yevatakuri vekutengesa vanobatana zvakare nehuwandu hwekutakura vanotakura, simba rakawandisa rinosunungurwa nenzira yechiedza, kushandura simba remagetsi kuita simba rechiedza. Kana reverse voltage inoshandiswa kune pn junction, zvakaoma kupinza zvishomanana zvekutakura vatakuri, saka luminescence haizoitike. Iyi mhando ye diode inogadzirwa zvichibva pamusimboti wejekiseni based luminescence inonzi light-emitting diode, inowanzopfupikiswa se LED.

Iyo inopenya maitiro e LED
Pasi pekurerekera kumberi kwe LED, vatakuri vechaji vanobayiwa, vanobatanidzwazve, uye vanovhenekerwa mu semiconductor chip ine shoma simba rechiedza. Iyo chip yakavharirwa mune yakachena epoxy resin. Kana ikozvino ichipfuura nepakati chip, maerekitironi akachajiswa zvisina kunaka anoenda kunzvimbo yegomba ine chaji yakanaka, kwaanosangana uye anosanganazve. Ose maerekitironi nemaburi panguva imwe chete anoparadza uye anoburitsa mafotoni.
Iyo yakakura iyo bandgap, inowedzera simba remafotoni anogadzirwa. Simba remafotoni rinoenderana neruvara rwechiedza. Muchiedza chinooneka, chiedza cheblue nepepuru chine simba guru, ukuwo orange nechitsvuku chine simba rakaderera. Nekuda kweakasiyana mabhendi mabhenji ezvigadzirwa zvakasiyana, anogona kuburitsa chiedza chemavara akasiyana.
Kana iyo LED iri kumberi kushanda mamiriro (kureva kuisa mberi voltage), ikozvino inoyerera kubva kune anode kuenda kune cathode ye LED, uye semiconductor crystal inoburitsa mwenje wemavara akasiyana kubva kuultraviolet kuenda kune infrared. Kusimba kwechiedza kunoenderana nehukuru hwezvino. Ma LED anogona kufananidzwa nehamburgers, apo zvinhu zvinopenya zvakafanana ne "nyama patty" mune sandwich, uye ma electrode epamusoro nepamusoro akafanana nechingwa chine nyama pakati. Kuburikidza nekudzidza kwezvinhu zvinopenya, vanhu vakagadzira zvishoma nezvishoma zvikamu zvakasiyana-siyana zve LED zvine ruvara rwechiedza chepamusoro uye kushanda nesimba. Kunyangwe paine shanduko dzakasiyana mu LED, iyo luminescent musimboti uye chimiro zvinoramba zvisina kushanduka. Jinjian Laboratory yakagadzira tambo yekuyedza inovhara machipisi kune zvigadziriso zvemwenje muindasitiri yeLED optoelectronic, ichipa mhinduro-yega inovhara zvese kubva kune zvigadzirwa kusvika kune zvigadzirwa zvekushandisa, kusanganisira kutadza kuongorora, hunhu hwezvinhu, kuyedza parameter, nezvimwewo, kubatsira vatengi. kunatsiridza mhando, goho, uye kuvimbika kwezvigadzirwa zve LED.

Zvakanakira mwenje we LED
1. Kuchengetedza magetsi: LED dzinoshandura simba remagetsi zvakananga kuva simba rechiedza, rinopedza hafu chete yemarambi echinyakare, iyo inobatsira kuderedza kushandiswa kwemafuta uye inodzivisa kukanganisa kumatunhu emotokari nekuda kwekuwanda kwekutakura ikozvino.
2. Kuchengetedzwa kwezvakatipoteredza: LED spectrum haina ultraviolet uye infrared rays, ine yakaderera kupisa chizvarwa, hapana mwaranzi, uye kuderera kupenya. Tsvina ye LED inodzokororwa, mecury haina, kusvibiswa-isina, yakachengeteka kubata, uye ndeye yakajairwa girinhi mwenje sosi.
3. Hupenyu hurefu: Hapana zvikamu zvakasununguka mukati memuviri wemwenje we LED, kudzivirira matambudziko akadai sekutsva kwefilament, deposition yekupisa, uye kuora kwechiedza. Pasi pezvakakodzera zvazvino uye magetsi, hupenyu hwesevhisi ye LED hunogona kusvika maawa 80000 kusvika ku100000, iyo yakareba kanopfuura kagumi kupfuura magetsi echinyakare. Iyo ine hunhu hwekutsiva imwe-nguva uye kushandiswa kwehupenyu hwese.
4. Kupenya kwepamusoro uye kupisa kwekushisa kwepamusoro: ma LED anoshandura zvakananga simba remagetsi kuva simba rechiedza, anogadzira kupisa kuduku, uye anogona kubatwa zvakachengeteka.
5. Saizi diki: Vagadziri vanogona kushandura zvakasununguka maitiro ezvigadziriso zvekuvhenekesa kuti vawedzere kusiyanisa kwemhando yemotokari. LED inofarirwa zvakanyanya nevagadziri vemotokari nekuda kwezvakanaka zvayo.
6. Kugadzikana kwepamusoro: ma LED ane simba rekuita seismic, akaputirwa mu resin, haasi nyore kuputsika, uye ari nyore kuchengeta uye kutakura.
7. High luminous kuchena: LED mavara akajeka uye akajeka, pasina kudiwa kwekusefa kwemwenje wemwenje, uye chikanganiso chekuvhenekera kwechiedza chiri pasi pegumi nanometers.
8. Nguva yekupindura inokurumidza: Ma LED haadi nguva yekupisa uye anogona kubudisa chiedza mumamicroseconds mashomanana, asi magirobhu egirazi echinyakare anoda kunonoka kwe 0.3 seconds. Mumashandisirwo akadai sematairi, kukurumidza kupindura kwema LED kunobatsira kudzivirira nekumashure kudhumhana kwekupedzisira uye kunatsiridza kuchengetedza kwekutyaira.
