Namhlanje i-LED ibe yinxalenye engafikelelekiyo ebomini bethu.Namhlanje, ndiza kukunika intshayelelo emfutshane malunga nombono, iimpawu, kunye nokuhlelwa.

Umbono we-LED

I-LED (i-Light Emitting Diode) sisixhobo esiqinileyo se-semiconductor esiguqula umbane ngokuthe ngqo kuKhanya.Intliziyo ye-LED yi-chip ye-semiconductor, kunye nesiphelo esinye esincanyathiselwe kwi-scaffold, enye isiphelo sayo i-electrode engalunganga, kunye nesinye isiphelo esiqhagamshelwe kwisiphelo esilungileyo sobonelelo lwamandla, ukuze yonke i-chip ifakwe kwindawo yombane. epoxy resin.

I-chip ye-semiconductor yenziwe ngamacandelo amabini, enye i-p-type semiconductor, apho imingxuma ilawula, kwaye enye i-semiconductor yohlobo lwe-n, apho ii-electron zilawula.Kodwa xa i-semiconductors ezimbini zixhunyiwe, "i-pn junction" yenza phakathi kwabo.Xa i-current isetyenziswe kwi-chip ngocingo, ii-electron zityhalwa kwi-p-region, apho ziphinda zihlangane kunye nomngxuma kwaye zikhuphe amandla ngendlela yeefotoni, yindlela ii-LED ezikhanya ngayo.Kwaye ubude bokukhanya, umbala wokukhanya, unqunywe yimpahla eyenza i-PN junction.

Iimpawu ze-LED

Iimpawu zangaphakathi ze-LED zigqiba ukuba ngowona mthombo wokukhanya ofanelekileyo ukuthatha indawo yomthombo wokukhanya wendabuko, unoluhlu olubanzi lwezicelo.

• Umthamo omncinci

I-LED ngokwesiseko yitshiphu encinci kakhulu efakwe kwi-epoxy resin, ke incinci kakhulu kwaye ilula kakhulu.

-Ukusetyenziswa kwamandla aphantsi

Ukusetyenziswa kwamandla e-LED kuphantsi kakhulu, ukuthetha ngokubanzi, i-LED yokusebenza kwamandla yi-2-3.6V.
Okwangoku ukusebenza ngu-0.02-0.03A.
Oko kukuthi, ayisebenzisi ngaphezu kwe-0.1W yombane.

• Ubomi Obude Benkonzo

Ngokufanelekileyo ngoku kunye ne-voltage, ii-LED zinokuba nobomi benkonzo ukuya kuthi ga kwiiyure ezingama-100,000.

• Ukukhanya okuphezulu kunye nobushushu obuphantsi

• Ukhuseleko lokusiNgqongileyo

Ii-LED zenziwe ngezinto ezingenabuthi, ngokungafani nezibane ze-fluorescent, eziqukethe i-mercury kwaye zibangele ukungcola.Zisenokwenziwa kwakhona.

• Yomelele kwaye ihlala ixesha elide

Ii-LED zifakwe ngokupheleleyo kwi-epoxy resin, eyomeleleyo kunezibane zokukhanya kunye neebhubhu ze-fluorescent.Kwakhona akukho nxalenye ekhululekileyo ngaphakathi kwesibane, okwenza ii-LED zingapheli.

Ulwahlulo lwe-LED

1, Ngokutsho ityhubhu yokukhupha ukukhanyaumbalaamanqaku

Ngokombala okhupha ukukhanya wetyhubhu ekhupha ukukhanya, inokwahlulwa ibe bomvu, i-orenji, eluhlaza (kunye nohlaza omthubi, umgangatho oluhlaza kunye nohlaza olusulungekileyo), eluhlaza okwesibhakabhaka njalo njalo.
Ukongeza, ezinye ii-LED ziqulethe iitshiphusi zemibala emibini okanye emithathu.
Ngokutsho kwe-diode ekhupha ukukhanya exutywe okanye engaxutywanga ne-scatterers, enemibala okanye engenambala, le mibala ingentla yohlukeneyo ye-LED inokwahlulwa ibe nemibala ecacileyo, engabonakaliyo, enemibala emhlophe kunye nokusabalalisa okungenambala kweentlobo ezine.
Ukusasaza ii-diode ezikhupha ukukhanya kunye nokukhanya - ii-diode ezikhuphayo zingasetyenziswa njengezibane zesalathisi.

2.Ngokuhambelana neempawu zokukhanyaumphezuluyetyhubhu ekhupha ukukhanya

Ngokweempawu zokukhanya okukhupha ukukhanya kwetyhubhu yokukhanya, inokwahlulwa ibe sisibane esijikelezileyo, isibane sesikwere, isibane esixande, ityhubhu yokukhanya yobuso, ityhubhu yecala kunye netyhubhu encinci yokufakelwa komphezulu, njl.
Isibane sesetyhula sahlulwe sibe yi-Φ2mm, Φ4.4mm, Φ5mm, Φ8mm, Φ10mm kunye ne-Φ20mm, njl.
Amazwe angaphandle adla ngokurekhoda i-Φ3mm ukukhanya-emitting diode njenge T-1, φ5mm njengoko T-1 (3/4), kunyeφ4.4mm njenge T-1 (1/4).

3.Ngokungqinelana neisakhiwoyeediode ezikhupha ukukhanya

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

4.Ngokutshoamandla okukhanya kunye nokusebenza ngoku

Ngokutsho kokukhanya okukhanyayo kunye nokusebenza kwangoku kwahlulwe kukukhanya okuqhelekileyo kwe-LED (i-luminous intensity 100mCD);
Ukuqina okukhanyayo phakathi kwe-10 kunye ne-100mCD kubizwa ngokuba yi-highlightness-emitting diode.
Umbane osebenzayo we-LED jikelele usuka kwi-mA ukuya kwishumi le-mA, ngelixa ukusebenza kwe-LED yangoku ephantsi ingaphantsi kwe-2mA (ukukhanya kuyafana nokwetyhubhu eqhelekileyo ekhupha ukukhanya).
Ukongeza kwezi ndlela zokuhlela zingentla, kukwakho iindlela zokuhlela ngezinto zechip kunye nomsebenzi.

UTed: inqaku elilandelayo likwathetha nge-LED.Ingaba yin?Nceda uhlale ubukele.
