Kule mihla i-LED ibe yinxalenye yobomi bethu engafikelelekiyo. Namhlanje, ndiza kukunika intshayelelo emfutshane malunga nengcamango, iimpawu kunye nokuhlelwa.

Ingcamango ye-LED

I-LED (i-Light Emitting Diode) sisixhobo se-semiconductor esiqinileyo esiguqula umbane ngqo ube yi-Light. Intliziyo ye-LED yi-semiconductor chip, enesiphelo esinye esiqhotyoshelwe kwi-scaffold, esinye isiphelo sayo yi-electrode engalunganga, kwaye esinye isiphelo siqhagamshelwe kwisiphelo esihle sombane, ukuze yonke i-chip ifakwe kwi-epoxy resin.

Itshiphu ye-semiconductor yenziwe ngamacandelo amabini, elinye lawo yi-semiconductor ye-p-type, apho kukho imingxunya elawula khona, elinye yi-semiconductor ye-n-type, apho kukho ii-electron ezilawula khona. Kodwa xa ezi semiconductor zimbini ziqhagamshelwe, kwakheka "i-pn junction" phakathi kwazo. Xa umsinga ufakwa kwi-chip ngentambo, ii-electron zityhalelwa kwindawo ye-p, apho zidibana khona nomngxuma kwaye zikhuphe amandla ngendlela yee-photons, yindlela ii-LED ezikhanya ngayo. Kwaye ubude bokukhanya, umbala wokukhanya, bumiselwa zizinto ezenza i-PN junction.

Iimpawu ze-LED

Iimpawu zangaphakathi ze-LED zimisela ukuba yeyona mthombo wokukhanya ufanelekileyo ukuthatha indawo yomthombo wokukhanya wendabuko, ineendlela ezahlukeneyo zokusetyenziswa.

• Umthamo Omncinci

I-LED ngokusisiseko yitshiphusi encinci kakhulu egqunywe kwi-epoxy resin, ngoko ke incinci kakhulu kwaye ilula kakhulu.

-Ukusetyenziswa kwamandla aphantsi

Ukusetyenziswa kwamandla e-LED kuphantsi kakhulu, ngokubanzi, i-voltage yokusebenza ye-LED yi-2-3.6V.
Umbane osebenzayo yi-0.02-0.03A.
Oko kukuthi, ayisebenzisi umbane ongaphezulu kwe-0.1W.

• Ubomi beNkonzo ende

Ngombane ofanelekileyo kunye ne-voltage, ii-LED zinokuba nobomi benkonzo obufikelela kwiiyure ezili-100,000.

• Ukukhanya Okuphezulu kunye nobushushu obuphantsi

• Ukhuseleko lweNdalo

Ii-LED zenziwe ngezinto ezingezizo iityhefu, ngokungafaniyo nezibane ze-fluorescent, eziqulathe i-mercury kwaye zibangela ungcoliseko. Zingaphinda zisetyenziswe.

• Yomelele kwaye Ihlala Ihleli

Ii-LED zigqunywe ngokupheleleyo kwi-epoxy resin, enamandla kuneebhalbhu zokukhanya kunye neetyhubhu ze-fluorescent. Akukho ndawo zikhululekileyo ngaphakathi kwesibane, nto leyo eyenza ii-LED zingonakalisi.

Ulwahlulo lwe-LED

1, Ngokwetyhubhu yokukhupha ukukhanyaumbalaamanqaku

Ngokwemibala ekhupha ukukhanya yetyhubhu ekhupha ukukhanya, inokwahlulwa ibe bomvu, iorenji, iluhlaza (kunye noluhlaza okwesibhakabhaka, uluhlaza oluqhelekileyo kunye noluhlaza olucocekileyo), luhlaza okwesibhakabhaka njalo njalo.
Ukongeza, ezinye ii-LED ziqulathe iitships zemibala emibini okanye emithathu.
Ngokwe-diode ekhupha ukukhanya exutywe okanye engaxutywanga nee-scatterers, ezinemibala okanye ezingenambala, imibala eyahlukeneyo ye-LED engentla ingahlulwahlulwa ibe yimibala ecacileyo, engenambala ecacileyo, enemibala ecacileyo kunye neentlobo ezine ze-scattering.
Ii-diode ezikhupha ukukhanya ezisasaza kunye nee-diode ezikhupha ukukhanya zingasetyenziswa njengezibane zokubonisa.

2. Ngokweempawu zezibane ezikhanyayoumphezuluyetyhubhu ekhupha ukukhanya

Ngokweempawu zomphezulu okhupha ukukhanya kwityhubhu ekhupha ukukhanya, ingahlulwa ibe sisibane esingqukuva, isibane esisikwere, isibane esixande, ityhubhu ekhupha ukukhanya kobuso, ityhubhu esecaleni kunye netyhubhu encinci yokufaka umphezulu, njl.
Isibane esijikelezayo sahlulwe saba yi-Φ2mm, Φ4.4mm, Φ5mm, Φ8mm, Φ10mm kunye ne-Φ20mm, njl.
I-Foreign idla ngokurekhoda i-Φ3mm light-emitting diode njenge-T-1, φ5mm njenge-T-1 (3/4), kunyeφ4.4mm njenge-T-1 (1/4).

3. Ngokwe-isakhiwoiidiode ezikhupha ukukhanya

Ngokwesakhiwo se-LED, kukho zonke ii-epoxy encapsulation, i-metal base epoxy encapsulation, i-ceramic base epoxy encapsulation kunye ne-glass encapsulation.

4. Ngokweamandla akhanyayo kunye nomsinga osebenzayo

Ngokwe-intensive ekhanyayo kunye ne-working current yahlulwe yaba yi-LED eqhelekileyo (intensive ekhanyayo yi-100mCD);
Ukukhanya okuphakathi kwe-10 kunye ne-100mCD kubizwa ngokuba yi-high brightness light-emitting diode.
Umsinga osebenzayo we-LED jikelele usuka kwi-mA ezilishumi ukuya kwi-mA ezininzi, ngelixa umsinga osebenzayo we-LED yamandla aphantsi ungaphantsi kwe-2mA (ukukhanya kufana noko kwetyhubhu eqhelekileyo ekhupha ukukhanya).
Ukongeza kwiindlela zokuhlela ezingentla, kukwakho neendlela zokuhlela ngokwezinto zetship kunye nomsebenzi.

UTed: inqaku elilandelayo likwathetha nge-LED. Yintoni leyo? Nceda uhlale ubukele.
