Kulezi zinsuku kuholele ukuthi kube yingxenye yempilo yethu engafinyeleleki. Namuhla, ngizokunikeza isingeniso esifushane somqondo, izici, kanye nokuhlukaniswa.

Umqondo we-LED

I-LED (i-Light Edit Diode) iyithuluzi eliqinile le-semiconductor eliguqula ugesi ngqo ekukhanyisweni. Inhliziyo ye-LED yi-Chip ye-semiconductor, enesiphetho esisodwa esinamathiselwe ku-scaffold, ukuphela okukodwa okuyi-electrode okungekuhle, kanti enye ixhumeke ekugcineni kwamandla kagesi, ukuze i-chip yonke ifakwe ku-resin ye-epoxy.

I-Chip ye-semiconductor yenziwa izingxenye ezimbili, enye yazo i-semiconductor ye-p-tex, lapho izimbobo zibusa, kanti enye yazo i-semiconductor, i-elektroni ebusa ngayo. Kepha lapho ama-semiconductors amabili exhunywe, amafomu we- "PN Junction" phakathi kwabo. Lapho kufakwa manje kwi-chip ngokusebenzisa ucingo, ama-elektroni adonswa esifundeni se-P-, lapho ahlangana khona nomgodi futhi akhipha amandla ngendlela ye-Photons, okuyindlela ekhanyayo. Futhi i-wavelength yokukhanya, umbala wokukhanya, kunqunywa ngezinto ezibonakalayo ezakha ukuhlangana kwe-PN.

Izici ze-LED

Izici ezihlangene ze-LED zinquma ukuthi ingumthombo omuhle kakhulu wokukhanya wokubuyisela umthombo wokukhanya kwendabuko, inezinhlobonhlobo zezicelo.

• Ivolumu encane

I-LED ngokuyisisekelo i-chip encane kakhulu efakwe ku-resin ye-epoxy, ngakho-ke incane kakhulu futhi ilula kakhulu.

-Ukusebenzisa amandla okusebenzisa amandla

Ukusetshenziswa kwamandla kwe-LED kuphansi kakhulu, ngokuvamile ukukhuluma, amandla okusebenza aholwa ngu-2-3.6v.
I-Working yamanje ingu-0.02-0.03A.
Lokho kusho ukuthi, akusebenzi kungabi ngaphezu kwe-0.1w kagesi.

• Impilo Yesevisi Ende

Ngokwamanje okulungile kanye nama-voltage, ama-LED angaba nempilo yenkonzo emahoreni angama-100,000.

• Ukukhanya okuphezulu nokushisa okuphansi

• Ukuvikelwa Kwezemvelo

Ama-LED enziwe ngezinto ezingezona ezinobuthi, ngokungafani namalambu we-fluorescent, aqukethe i-mercury futhi adale ukungcoliswa. Zingaphinde zisetshenziswe kabusha.

• Uqine futhi uhlala isikhathi eside

Ama-LED ahlanganiswe ngokuphelele e-epoxy resin, enamandla kunawo womabili ama-bulbs namashubhu we-fluorescent.Kukhona futhi azikho izingxenye ezivulekile ngaphakathi kwesibani, okwenza ama-LED angenakuqhathaniswa.

Ukuhlukaniswa kwe-LED

1, ngokuya nge-tube yokukhanyisa ekhanyayoumbalaamaphuzu

Ngokusho kombala wokukhanya okukhanyayo we-tube yokukhipha okukhanyayo, ingahlukaniswa ibe yi-Red, Orange, eluhlaza okotshani (oluhlaza okotshani (oluhlaza okotshani oluhlaza okotshani, oluhlaza okotshani nokuhlaza okwesibhakabhaka), oluhlaza okwesibhakabhaka nokunye.
Ngaphezu kwalokho, amanye ama-LED aqukethe ama-chips wemibala emibili noma emithathu.
Ngokusho kwe-diode ekhishini ekhanyayo exutshwe noma engahlanganisiwe nabasanda kuhlalisana, anemibala noma engenamibala, imibala ehlukahlukene engenhla ingahlukaniswa ibe ngombala osobala, onombala onombala wokuhlakaza kanye nemibala yezinhlobo ezine.
Ukusakaza ama-diode akhanyisiwe okukhanyayo nokukhanya - Ukukhipha ama-diode angasetshenziswa njengamalambu wenkomba.

2.Faka kwizici ze-luminousngaphandleye-tube yokukhanyisa ekhanyayo

Ngokwesici sokukhanya okukhanyayo kokukhanya kokukhanya okukhanyayo, kungahlukaniswa isibani esiyindilinga, isibani sesikwele, isibani esingunxande, ishubhu elikhanyayo elikhipha, ishubhu eliphansi lokufakwa kwendawo, njll.
Isibani esiyindilinga sihlukaniswe yi-φ2mm, φ4.4mm, φ00mm, φ00mm, φ000mm, φ20mm, ntp.
Imvamisa igcizelela i-φ3mm ekhipha ukukhanya i-diode njenge-T-1, φ5mm njengoba t-1 (3/4), futhiφ4.4mm njengoba t-1 (1/4).

3.According to theukwakhekakokufakelwa okukhanyayo okukhanyayo

Ngokwesakhiwo se-LED, kunenzuzo yonke ye-epoxy, i-Metal Base Epoxy Encopsetion, Curamic base epoxy embhalweni kanye nenkan.

4.According toukuqina okukhanyayo nokusebenza kwamanje

Ngokwe-luminous ukuqina nokusebenza kwamanje kuhlukaniswe ngobuhlakani obujwayelekile bokukhanya kwe-LED (i-luminous ubukhulu 100mcd);
Ukuqina okukhanyayo phakathi kwe-10 no-100mcd kubizwa ngokuthi ukugqama okuphezulu okukhanyisa ukukhanya.
Ukusebenza kwamanje kwe-General LED kuvela ku-MA eyishumi kuya ku-MA inqwaba ye-MA, kuyilapho i-LED ye-LED ephansi ingaphansi kwe-2A
Ngaphezu kwezindlela zokuhlukaniswa ngenhla, kukhona nezindlela zokuhlukaniswa ngezinto ze-chip nakwosebenza.

UTed: Isihloko esilandelayo sibuye sibe ne-LED. Kwenzenjani? Sicela uhlale ubukele.
