Eminyakeni yakamuva,Izibani zomgwaqo ze-LEDsezidume kakhulu ngenxa yokonga kwazo amandla kanye nokuqina. Lezi zibani zenzelwe ukukhanyisa imigwaqo nezikhala zangaphandle ngokukhanya okukhanyayo nokugxilile. Kodwa ingabe wake wazibuza ukuthi yini ngempela ngaphakathi kwesibani somgwaqo we-LED? Ake sibheke ukusebenza kwangaphakathi kwalezi zixazululo zokukhanyisa ezisebenza kahle kakhulu.
Uma uthi nhlá, ilambu le-LED lomgwaqo libonakala liyisibani esilula. Nokho, izingxenye zayo zangaphakathi ziyinkimbinkimbi kakhulu. Izingxenye eziyinhloko zamalambu omgwaqo we-LED zifaka ama-chips e-LED, abashayeli, amasinki okushisa, namadivayisi abonakalayo.
Ama-chips e-LED
Ama-LED chips ayinhliziyo nomphefumulo wamalambu omgwaqo. Lezi zixhobo ezincane ze-semiconductor ziyakhanya lapho umsinga kagesi udlula kuwo. Ubuchwepheshe be-LED buye benza izinguquko embonini yokukhanyisa ngokunikeza amandla aphezulu kanye nempilo ende. Ama-chips e-LED asetshenziswa izibani zasemgwaqweni enziwe nge-gallium nitride, into ekhiqiza ukukhanya okukhanyayo, okuqondisayo.
Umshayeli we-SPD
Umshayeli ungenye ingxenye ebalulekile yezibani zomgwaqo ze-LED. Ilawula ukusebenza kwama-chips e-LED, iqinisekisa ukuthi zithola i-voltage efanele kanye nezamanje. Izishayeli ze-LED ziklanyelwe ukuguqula i-alternating current (AC) ukusuka kokokufaka kokuphakelwa kwamandla ukuya kweyamanje eqondile (DC) edingwa yi-LED. Ziphinde zinikeze imisebenzi yokulawula ehlukahlukene, njengokufiphala nokulungiswa kombala, okuvumela ukuguquguquka okukhulu kumklamo wokukhanyisa nokonga amandla.
Usinki oshisayo
Osinki bokushisa badlala indima ebalulekile ekugcineni impilo yezibani zomgwaqo ze-LED. Ngenxa yokusebenza kahle okuphezulu kwama-chips e-LED, akhiqiza ukushisa okuncane kunemithombo yokukhanyisa evamile. Nokho, ukushisa okweqile kusenganciphisa ukuphila nokusebenza kwe-LED. I-heater sink, ngokuvamile eyenziwe nge-aluminium, inesibopho sokuqeda ukushisa okudlulele futhi ivimbele i-LED ekushiseni ngokweqile. Ngokuqinisekisa ukuphathwa okwanele kokushisa, amasinki okushisa akhulisa ukwethembeka nokuqina kwezibani zomgwaqo.
I-Optics
I-Optics kumalambu omgwaqo we-LED alawula ukusatshalaliswa nokuqina kokukhanya. Basiza ukuqondisa ukukhanya kusuka kuma-LED chips kuya endaweni oyifunayo kuyilapho benciphisa ukungcoliswa kokukhanya nokuxhopha. Amalensi nezibonisi zivame ukusetshenziswa ekukhanyisweni komgwaqo ukuze kuzuzwe ukusatshalaliswa kokukhanya okunembile, kukhuliswe ukumbozwa kokukhanya nokusebenza kahle. Ama-Optics anika amandla ukulawula okuqondile kwe-beam ngisho nokukhanyiswa kwemigwaqo nezikhala zangaphandle.
Iyunithi yamandla
Ngaphezu kwalezi zingxenye eziyinhloko, kunezinye izici ezisekelayo ezifaka isandla ekusebenzeni kwezibani zomgwaqo ze-LED. Iyunithi yamandla inesibopho sokulawula kanye nokwenza kahle amandla anikezwe umshayeli. Iqinisekisa ukusebenza okuzinzile kungakhathaliseki ukunikezwa kwamandla noma ukushintshashintsha okungenzeka.
Izindawo ezivalekile nezibiyelwe
Ukwengeza, izindawo ezivalekile nezivalekile zivikela izingxenye zangaphakathi ezintweni zemvelo ezinjengomswakama, uthuli, nokushintsha kwezinga lokushisa. Izibani zasemgwaqweni ze-LED zenzelwe ukumelana nezimo zezulu ezinzima, ziqinisekise ukusebenza okuthembekile ngisho nasezimweni ezimbi kakhulu.
Ngombono wami
Intuthuko kubuchwepheshe bokukhanyisa emigwaqweni ye-LED iguqule indlela esikhanyisa ngayo imigwaqo yethu nezindawo ezingaphandle. Uma kuqhathaniswa nezixazululo zokukhanyisa zendabuko, izibani zasemgwaqweni ze-LED zingonga amandla abalulekile, ngaleyo ndlela zinciphise ukusetshenziswa kukagesi kanye nokukhishwa kwekhabhoni. Ukwengeza, impilo yabo ende yesevisi inciphisa isidingo sokushintshwa njalo, okunomthelela ekongeni kwezindleko ezinkulu komasipala nemiphakathi.
Ngaphezu kwalokho, ukuqondiswa kwama-LED kuqinisekisa ukusatshalaliswa kokukhanya okunembile, kunciphisa ukungcoliswa kokukhanya nokunciphisa ukungakhululeki kubahlali. Lobu buchwepheshe bokukhanyisa obusebenzayo buguqula indawo yasemadolobheni, buhlinzeke ngemigwaqo ephephile, ekhanyiswe kahle kwabahamba ngezinyawo nabashayeli bezimoto.
Ngokufigqiwe
Izibani zasemgwaqweni ze-LED zenziwe ngezinto ezihlukahlukene eziyinkimbinkimbi ezisebenza ndawonye ukuze zinikeze ukukhanya okuzonga amandla nokuthembekile. Ama-chips e-LED, abashayeli, osinki bokushisa, nama-optics kuhlangana ukudala isisombululo sokukhanyisa esisebenza kahle nesimeme. Njengoba ubuchwepheshe be-LED buqhubeka buthuthuka, singabheka phambili ezinkethweni zokukhanyisa emgwaqweni ezisebenza kahle kakhulu nezintsha esikhathini esizayo.
Uma unentshisekelo kumalambu asemgwaqweni, wamukelekile ukuthintana nomkhiqizi wokukhanya oholwa yilanga u-TIANXIANG kuFunda kabanzi.
