Ubuhlalu be-LED bumele ama-diode akhipha ukukhanya.
Umgomo wayo okhanyayo ukuthi i-PN junction terminal voltage yenza umgoqo othile ongase ube khona, lapho i-voltage yokuchema eya phambili yengezwa, isithiyo esingaba khona siyehla, futhi abathwali abaningi ezindaweni zika-P no-N basakazekela komunye nomunye. Njengoba ukuhamba kwe-electron kukhulu kakhulu kunokuhamba kwembobo, inani elikhulu lama-electron lizosakazeka ku-P-region, okuhlanganisa umjovo wabathwali abambalwa ku-P-region. Lawa ma-electron ahlangana nezimbobo ebhendini ye-valence, futhi amandla avelayo akhululwa njengamandla okukhanya.
Izici zayo zimi kanje:
1. Amandla kagesi: Ubuhlalu bezibani ze-LED zisebenzisa amandla kagesi aphansi, amandla kagesi phakathi kuka-2-4V. Ngokusho kwemikhiqizo ehlukene, iqhutshwa ukunikezwa kwamandla kagesi okuphephile kunamandla kagesi aphezulu, alungele izindawo zomphakathi.
2. Okwamanje: ukusebenza kwamanje kungu-0-15mA, futhi ukukhanya kukhanya ngokunyuka kwamandla.
3. Ukusebenza kahle: ukusetshenziswa kwamandla okungaphansi ngo-80% kunezibani ze-incandescent ezinokukhanya okufanayo kokukhanya.
4. Ukusebenza: Iyunithi ngayinye ye-LED chip iyisikwele esingu-3-5mm, ngakho-ke ingalungiselelwa ibe yizimo ezihlukahlukene zamadivayisi, futhi ifanele indawo eguquguqukayo.
5. Isikhathi sokuphendula: Isikhathi sokuphendula sesibani salo se-incandescent yizinga le-millisecond, futhi leso sibani se-LED siyileveli ye-nanosecond.
6. Ukungcoliswa kwemvelo: Ayikho i-mercury yensimbi eyingozi.
7. Umbala: Umbala ungashintshwa ngokwamanje, uholwe ngendlela yokuguqulwa kwamakhemikhali, ulungise isakhiwo sebhendi kanye negebe lebhande lempahla, ukuze kuzuzwe ukukhanya okubomvu, okuphuzi, okuluhlaza okwesibhakabhaka, okusawolintshi okunemibala eminingi. Isibonelo, lapho i-current ephansi iyi-LED ebomvu, ngokukhula kwamanje, ingashintsha i-orange, iphuzi, futhi ekugcineni ibe luhlaza.
Imingcele yayo ichazwa kanje:
1.Ukukhanya
Intengo yobuhlalu be-LED ihlobene nokukhanya.
Ukukhanya okujwayelekile kobuhlalu kungama-60-70 lm. Ukukhanya okujwayelekile kwesibani se-bulb kungu-80-90 lm.
Ukukhanya kokukhanya okubomvu okungu-1W ngokuvamile kungu-30-40 lm. Ukukhanya kokukhanya okuluhlaza okungu-1W ngokuvamile kungu-60-80 lm. Ukukhanya kokukhanya okuphuzi okungu-1W ngokuvamile kungu-30-50 lm. Ukukhanya kokukhanya okuluhlaza okungu-1W kuvamise ukuba ngu-20-30 lm.
Qaphela: ukukhanya kwe-1W kungu-60-110LM. 3W ukukhanya kufika ku-240LM. I-5W-300W iyi-chip ehlanganisiwe, enephakheji yochungechunge/ehambisanayo, incike kakhulu ekutheni ingakanani yamanje, i-voltage.
Ilensi ye-LED: I-PMMA, i-PC, ingilazi yokubona, ijeli ye-silica (ijeli ye-silica ethambile, ijeli ye-silica eqinile) nezinye izinto ngokuvamile zisetshenziselwa ilensi eyinhloko. Uma i-engeli ibe nkulu, iphakamisa ukusebenza kahle kokukhanya. Ngelensi encane ye-Angle LED, ukukhanya kufanele kube kude.
2. Ubude begagasi
Ubude beza obufanayo nombala kwenza intengo ephezulu.
Ukukhanya okumhlophe kuhlukaniswe ngombala ofudumele (ukushisa kombala 2700-4000K), omhlophe oqondile (ukushisa kombala 5500-6000K) nomhlophe obandayo (ukushisa kombala ngaphezu kuka-7000K).
Isibani esibomvu: ibhendi engu-600-680, engu-620,630 yayo esetshenziselwa izibani zasesiteji futhi i-690 iseduze ne-infrared.
I-Blu-ray: Ibhendi engu-430-480, engu-460,465 yayo esetshenziselwa kakhulu izibani zasesiteji.
Ukukhanya okuluhlaza: Ibhendi engu-500-580, engu-525,530 yayo esetshenziselwa kakhulu izibani zasesiteji.
3. I-engeli ekhanyayo
Amaledi ngezinhloso ezahlukene akhipha ukukhanya ngama-engeli ahlukene. I-Engeli ekhanyayo ekhethekile ibiza kakhulu.
4. Ikhono le-Antistatic
Ikhono le-Antistatic lobuhlalu besibani se-LED linokuphila isikhathi eside, ngakho-ke intengo iphezulu. Ngokuvamile bungaphezu kuka-700V ubuhlalu besibani se-antistatic LED bungasetshenziswa ekukhanyisweni kwe-LED.
5. Ukuvuza kwamanje
Ubuhlalu besibani se-LED buwumzimba okhanyayo onendlela eyodwa. Uma kukhona i-reverse current, ibizwa ngokuthi ukuvuza, ukuvuza kwamanje ubuhlalu besibani se-LED kunokuphila okufushane kanye nenani eliphansi.
Eurbornikhiqiza ama-Outdoor Lights e-China. Sihlala sikhetha uhlobo oluhambisanayo ngokusho kwezibani futhi sizama konke okusemandleni ethu ukwenza imikhiqizo iphelele.
