Kule mihla kukhokelwa kuye kwaba yinxalenye yobomi bethu. Namhlanje, ndiza kukunika intshayelelo emfutshane yengcinga, iimpawu kunye nokuhlelwa.

Ingcinga yokukhokelwa

I-LED (ekukhanyiseni i-Diode) sisixhobo esiqinileyo se-semiconductor esiguqula umbane ngqo. Intliziyo ye-LED yi-semiconductor chip, kunye nesiphelo esinye esiqhotyoshelwe, esinye isiphelo se-electrode, kwaye esinye isiphelo sidityaniswe kwisiphelo esifanelekileyo sombane.

I-semiconductorctorch yenziwa ngamacandelo amabini, enye ye-p-Chwether yohlobo lwe-semiconductor, apho imingxunya ilawula khona, kwaye enye yohlobo lwe-semiconductor, apho kulawula khona i-electrone. Kodwa xa le mithambo mibini iqhagamshelwe, "i-pn junction" phakathi kwazo. Xa isetyenzisiwe yangoku kwi-chip ngokusebenzisa ucingo, ii-elektroniki zityhalelwe kwingingqi ye-P-, apho ziphinde zadibana nomngxunya kwaye zinamandla anemifanekiso kwifoto, yiyo i-LOPLE. Kwaye i-wavelect yokukhanya, umbala wokukhanya, ugqitywe ngumbandela owenza i-PN Junction.

Iimpawu ze-LED

Iimpawu ze-Intrinsic ze-LED ichonge ukuba yeyona mthombo ulungileyo wokutshintsha umthombo wokukhanya wesintu, unoluhlu olubanzi lwezicelo.

• Umthamo omncinci

I-LED i-of ngokusisiseko i-chip encinci kakhulu i-epopy resen, ke incinci kakhulu kwaye ilula kakhulu.

-Ukuzisela amandla

Ukusetyenziswa kwamandla kukhutshelwe kakhulu, khetha ivolthi esebenzayo, i-LED ye-LEED yi-2-3.6V.
Ukusebenza okwangoku yi-0.02-0.03a.
Oko kukuthi, inokutya okungaphezulu kwe-0.1w yombane.

• Ubomi obude bobomi

Nge-voltage ekhoyo nevolthi, i-LED inokuba nobomi benkonzo ukuya kuthi ga kwiiyure eziyi-100,000.

• Ukukhanya okuphezulu kunye nobushushu obuphantsi

• UKUKHUSELEKELA KWESICELO

I-LED yenziwa ngezinto ezingenatyhefu, ngokungafaniyo nezibane ze-fluorescent, eziqukethe i-mercury kwaye ibangele ungcoliseko. Banokuphinda baphinde baphinde baphinde baphinde baphinde baphinde baphinde baphinde baphinde baphinde baphinde baphinde baphinde baphinde baphinde.

• Yomelele kwaye iqine

I-LEDS ingenela i-Epoxy Retin, eyomeleleyo kuneebhulukhwe ezikhanyayo kunye neebhulukhwe zeFluorescent.Ingabikho zinxalenye ezikhululekileyo ngaphakathi kwesibane, nto leyo eyenza ukuba i-LEDS ayihlali.

Ukwahlula-hlula kwe-LED

I-1, ngokwe-tyhel yokukhanyaumbalaAmanqaku

Ngokutsho kwesibane ekutyibilikeni kwetyhubhu yokukhanya, inokwahlulwa ibe yi-Red, orenji, eluhlaza (kwaye ityheli eluhlaza, eluhlaza kwaye icocekile kwaye kunjalo.
Ukongeza, ezinye ii-LED ziqukethe imibala emibini okanye emithathu.
Ngokutsho kokukhanya komgangatho oxutywe okanye engadityaniswanga kunye nombala, unombala okanye ongenabala, le mibala ingentla eyahlulwe yasasazwa kwiindidi ezine.
Ukusasaza ii-Dodwes zokukhuphela ukukhanya kunye nee-Dods zokukhuphela ezikhutshelweyo zingasetyenziswa njengezibane zesalathisi.

2.Accoducation kwimpawu ze-lemunousumphezuluyetyhubhu yokukhanya

Ngokweempawu zokukhanya okuphekishileyo zokukhanya kokukhanya, ziyahlulwa zibe zizibane ezijikelezileyo, isibane esikwere, isibane esijikelezayo, ityhubhu ekhupha ityhubhu, ityhubhu yecala eliphantsi.
Isibane esijikelezileyo sahlulwe sayi-φ2mm, ¶4.4mm, φ5mm, φ8mm, φ10mm kwaye njlm.
Ilinye ilizwe idla ingxelo irekhoda i-φ3mm ye-diode ye-Diode njenge-T-1, φI-5mm ye-T-1 (3/4), kwayeφ4.4mm njenge-t-1 (1/4).

3.Ukuya kwiUlwakhiwoIi-Deods ezikhuphayo

Ngokwakwimo ye-LED, kukho konke ukupakishwa kwe-Epoxy, isiseko sensimbi ye-eporaxy e-Epoxy Excappation kunye neglasi yeglasi.

4.UkuyaUbunzulu boKhanya kunye nokusebenza okwangoku

Ngokutsho kobunzulu bento yokukhanya kunye nokusebenza kwangoku ngokwahlulahlulwe ngokuqaqambileyo okuqhelekileyo kwe-LED
Ubunzulu obukhanyayo phakathi kwe-10 ne-100mcd bubizwa ngokuba kukukhanya okuphezulu kokukhanya kwe-diode.
Ukusebenza okwangoku kwe-LE Jikelele kuvela kwishumi ma ukuya kwi-Mouzn Ma, ngelixa usebenza ngoku i-LED yangoku ye-LED ingaphantsi kwe-2ma
Ukongeza kwezi ndlela zingezantsi zokuhlelwa, kukwakhona iindlela zokwahlulahlula izinto ze-chip kunye nomsebenzi.

UTed: Inqaku elilandelayo limalunga ne-LED. Ingaba yin? Nceda uhlale uthandwa.
