I-LED ikhiqiza kanjani ukukhanya?

I-Electroluminescence inqubo lapho ama-LED (Light Emitting Diodes) akhiqiza ukukhanya. Isebenza kanje:

I-1-Semiconductor Material: Impahla ye-semiconductor, ngokuvamile eyingxube yezinto ezifana ne-phosphorous, i-arsenic, noma i-gallium, isetshenziselwa ukwenza i-LED. Kokubili indawo yohlobo lwe-n (negative), enama-electron amaningi, kanye nesifunda sohlobo lwe-p (positive), esinokuntuleka kwama-electron (izimbobo), kukhiqizwa lapho i-semiconductor ifakwe ukungcola.

I-2-Electron-Hole Recombination: Ama-electron asuka endaweni yohlobo lwe-n aphoqelelwa ukuya endaweni yohlobo lwe-p lapho i-voltage ibekwe ngaphesheya kwe-LED. Lawa ma-electron aphinde ahlangane nezimbobo endaweni yohlobo lwe-p.

I-3-Photon Emission: Amandla akhishwa njengokukhanya (amafotoni) phakathi nale nqubo yokuhlanganisa kabusha. Ibhande lamandla le-semiconductor esetshenzisiwe linquma umbala wokukhanya okukhishwayo. Ukukhanya kuvela ngemibala ehlukahlukene kuye ngezinto ezibonakalayo.

4-Ukusebenza kahle: Njengoba iningi lamandla kuma-LED liguqulwa libe ukukhanya kunokushisa-inkinga evamile ngama-incandescent bulbs-ama-LED asebenza kahle ngendlela emangalisayo.

I-5-Encapsulation: Ngokufaka i-LED ku-resin ecacile noma ilensi, ukukhanya okukhiphayo kuvame ukuthuthukiswa. Lokhu kungasiza futhi ukusabalalisa ukukhanya futhi kukwenze kubukeke kangcono.

Uma kuqhathaniswa nezindlela zokukhanyisa ezivamile, le ndlela yenza ama-LED akwazi ukunikeza ukukhanya okuqinile, okugxilile kuyilapho esebenzisa amandla amancane kakhulu.

Ngaphandle kokuhlala isikhathi eside nokusebenza kahle kwawo, izibani ze-LED zingaba nenani lezinkinga ezijwayelekile, njenge:
1) Ukushintshashintsha Kwezinga Lokushisa Lombala: Ukukhanyisa okungafani endaweni kungase kubangele ukushintsha kwezinga lokushisa lombala phakathi kwamaqoqo amalambu e-LED.

2)I-Flickering: Uma isetshenziswa nezishintshi ze-dimmer ezingahambelani noma uma kunezinkinga ngokuphakelwa kukagesi, amalambu athile e-LED angase acwayize.

3)Ukushisa ngokweqile: Ama-LED akhiqiza ukushisa okuncane kunezibani ezivamile, kodwa ukuchithwa kokushisa okunganele kungabangela ukushisa ngokweqile, okunganciphisa ukuphila kwama-bulb.

4) Izinkinga Zomshayeli: Ukuze ulawule amandla, izibani ze-LED zidinga abashayeli. Ukukhanya kungase kucwayize, kufiphale, noma kumise ukusebenza ngokuphelele uma umshayeli engasebenzi kahle noma kuyikhwalithi ephansi.

I-5) Ukuvumelana Kokufiphala: Izinkinga zokusebenza zingase ziphakame ngoba ezinye izibani ze-LED azihambisani nokushintsha kwe-dimmer yamanje.

I-6) I-Angle ye-Beam Elinganiselwe: Ukukhanya okungalingani kungabangelwa izibani ze-LED ezine-engeli elinganiselwe ye-beam, okungenzeka ingafaneleki izinhlelo zokusebenza eziningi.

I-7) Izindleko Zokuqala: Nakuba izibani ze-LED zonga imali ngokuhamba kwesikhathi, zingabiza kakhulu ukuthenga ekuqaleni kunama-bulb avamile.

8) Ukukhathazeka Kwemvelo: Uma kungalahlwanga ngendlela efanele, ukulandelela amazinga ezinto eziyingozi njengomthofu noma i-arsenic etholakala kwamanye amalambu e-LED angafaka engozini indawo ezungezile.

9)Ukuhlukahluka Kwekhwalithi: Kunezimpahla eziningi ze-LED ezihlukene emakethe, futhi akuzona zonke ezikhiqizwa ngamazinga afanayo, okubangela ukuhlukahluka kokuphila isikhathi eside nokusebenza.

10)Ukungahambisani Nokunye Ukulungiswa: Ama-LED athile, ikakhulukazi lawo enzelwe ama-incandescent avamile, awakwazanga ukusebenza kahle ezimisweni ezithile.

Ukukhetha izinto zekhwalithi ephezulu, ukwenza isiqiniseko sokuthi zisebenza nezinhlelo zamanje, futhi ngokuya ngemiyalelo yokufaka kuvame ukudingekile ukuxazulula lezi zinkinga.

Kunemigqa eminingi ekhanyayo ongakhetha kuyo emakethe manje, njengokuthiI-COB stripI-CSP strip, ehlukile ngeUmthamo wokuhweba we SMD, xhumana nathi uma udinga amasampula okuhlolwa.
