I-LED ikhiqiza kanjani ukukhanya?

I-Electroluminescence inqubo lapho ama-LED (Light Emitting Diodes) ekhiqiza khona ukukhanya. Nansi indlela esebenza ngayo:

Izinto ze-1-Semiconductor: Izinto ze-semiconductor, ngokuvamile ingxube yezinto ezifana ne-phosphorus, i-arsenic, noma i-gallium, zisetshenziselwa ukwenza i-LED. Kokubili indawo yohlobo lwe-n (negative), enama-electron amaningi, kanye nesifunda sohlobo lwe-p (positive), esintula ama-electron (imigodi), kukhiqizwa lapho i-semiconductor ixutshwe nokungcola.

Ukuhlanganiswa Kwezimbobo Ezi-2 Zama-Electron: Ama-electron avela endaweni yohlobo lwe-n aphoqeleka ukuya esifundeni sohlobo lwe-p lapho kufakwa i-voltage kuyo yonke i-LED. Lawa ma-electron ahlangana kabusha nezimbobo esifundeni sohlobo lwe-p.

Ukukhishwa kwe-Photon okungu-3: Amandla akhishwa njengokukhanya (ama-photon) phakathi nale nqubo yokuhlanganisa kabusha. Igebe lamandla lezinto ze-semiconductor ezisetshenziswayo linquma umbala wokukhanya okukhishwayo. Ukukhanya kuza ngemibala ehlukahlukene kuye ngokuthi izinto zinjani.

4-Ukusebenza Kahle: Njengoba iningi lamandla kuma-LED liguqulwa libe ukukhanya kunokushisa—inkinga evamile ngama-incandescent bulbs avamile—ama-LED asebenza kahle kakhulu.

5-Ukufakwa kwe-Encapsulation: Ngokufaka i-LED ku-resin noma ilensi ecacile, ukukhanya ekukhiphayo kuvame ukuthuthukiswa. Lokhu kungasiza futhi ekusabalaliseni ukukhanya futhi kukwenze kubukeke kangcono.

Uma kuqhathaniswa nezindlela zokukhanyisa ezivamile, le ndlela ivumela ama-LED ukuthi anikeze ukukhanya okunamandla, okugxilile ngenkathi esebenzisa amandla amancane kakhulu.

Naphezu kokuphila isikhathi eside nokusebenza kahle, izibani ze-LED zingaba nezinkinga eziningana ezivamile, njenge:
1) Ukushintshashintsha Kwezinga Lokushisa Lombala: Ukukhanya okungalingani endaweni kungabangelwa ukushintsha kwezinga lokushisa lombala phakathi kwenqwaba yezibani ze-LED.

2) Ukufiphaza: Uma kusetshenziswa nezinkinobho ze-dimmer ezingahambisani noma uma kunezinkinga ngokunikezwa kwamandla, izibani ezithile ze-LED zingafiphaza.

3) Ukushisa ngokweqile: Ama-LED akhiqiza ukushisa okuncane kunezibani ezivamile, kodwa ukushabalalisa ukushisa okunganele kungabangela ukushisa ngokweqile, okunganciphisa isikhathi sokuphila kwama-bulb.

4) Izinkinga Zomshayeli: Ukuze kulawulwe amandla, izibani ze-LED zidinga abashayeli. Ukukhanya kungase kukhanye, kufiphale, noma kuyeke ukusebenza ngokuphelele uma umshayeli engasebenzi kahle noma esezingeni eliphansi.

5) Ukuhambisana Kokufiphaza: Izinkinga zokusebenza zingase zivele ngoba ezinye izibani ze-LED azihambisani nezinkinobho zokufiphaza zamanje.

6) I-Angle Yomsebe Olinganiselwe: Ukukhanya okungalingani kungabangelwa izibani ze-LED ezine-engeli yomsebe elinganiselwe, okungase kungafaneleki ezinhlelweni eziningi.

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

8) Ukukhathazeka Ngezemvelo: Uma kungalahlwa ngendlela efanele, amazinga amancane ezinto eziyingozi njenge-lead noma i-arsenic etholakala kwezinye izibani ze-LED angafaka imvelo engozini.

9) Ukuguquguquka Kwekhwalithi: Kunezimpahla eziningi ze-LED ezihlukene emakethe, futhi akuzona zonke ezikhiqizwa ngezindinganiso ezifanayo, okubangela ukuguquguquka kokuphila isikhathi eside nokusebenza.

10) Ukungahambelani Nezinto Ezithile Ezifakiwe: Ama-bulb athile e-LED, ikakhulukazi lawo enzelwe ama-bulb avamile angenakukhanya, awakwazanga ukusebenza kahle ezintweni ezithile ezifakiwe.

Ukukhetha izinto ezisezingeni eliphezulu, ukuqinisekisa ukuthi zisebenza nezinhlelo zamanje, kanye nemiyalelo yokufaka kuyadingeka njalo ukuxazulula lezi zinkinga.

Kunezinhlobo eziningi zokukhanya ongakhetha kuzo emakethe manje, njengeUmugqa we-COBI-CSP strip, ehlukile kune-Umugqa we-SMD, xhumana nathi uma udinga amasampula okuhlolwa.
