Kungani abantu abaningi bethanda ukusebenzisa izibani ze-LED esikhundleni sezibani ze-incandescent?

Nazi ezinye iziqhathaniso, mhlawumbe kungasisiza sithole impendulo.

Umehluko wokuqala phakathi kwamalambu e-incandescent namalambu e-LED yisimiso esikhipha ukukhanya.Isibani se-incandescent sibizwa nangokuthi i-bulb kagesi.Isimiso sayo sokusebenza siwukuthi ukushisa kukhiqizwa lapho i-current idlula i-filament.I-spiral filament iqoqa ngokuqhubekayo ukushisa, okwenza izinga lokushisa lomucu libe ngaphezu kuka-2000 degrees Celsius.Lapho umucu usesimweni esishisayo, ubukeka njengensimbi ebomvu.Ingakhipha ukukhanya njengoba ikhanya.

Ukuphakama kwezinga lokushisa kwe-filament, ukukhanya kukhanya, ngakho kubizwa ngokuthi isibani se-incandescent.Lapho izibani ze-incandescent zikhipha ukukhanya, inani elikhulu lamandla kagesi lizoguqulwa libe amandla okushisa, futhi ingxenye encane kakhulu kuphela engaguqulwa ibe amandla okukhanya awusizo.

Amalambu e-LED abizwa nangokuthi ama-light-emitting diode, okungamadivaysi e-solid state semiconductor akwazi ukuguqula ugesi ube ukukhanya.Inhliziyo ye-LED iyi-chip ye-semiconductor, umkhawulo owodwa we-chip unamathiselwe kubakaki, umkhawulo owodwa uyisigxobo esingalungile, kanti omunye umkhawulo uxhunywe esigxotsheni esihle sokunikezwa kwamandla, ukuze yonke i-chip ihlanganiswe. nge-epoxy resin.

I-wafer ye-semiconductor yakhiwe izingxenye ezintathu, ingxenye eyodwa i-semiconductor yohlobo lwe-P, lapho izimbobo zibusa khona, enye iphetho iyi-semiconductor yohlobo lwe-N, lapha ikakhulukazi ama-electron, kanti phakathi ngokuvamile i-quantum kahle eno-1 kuya ku-5. imijikelezo.Lapho ukusebenza kwamanje ku-chip ngocingo, ama-electron kanye nezimbobo zizophushwa emithonjeni ye-quantum.Emithonjeni ye-quantum, ama-electron nezimbobo kuhlangana kabusha bese kuphuma amandla ngendlela yama-photons.Lona umgomo wokukhishwa kokukhanya kwe-LED.

Umehluko wesibili usemisebeni yokushisa ekhiqizwa yilaba ababili.Ukushisa kwesibani se-incandescent kungazwakala ngesikhathi esifushane.Amandla amakhulu, ukushisa kakhulu.Ingxenye yokuguqulwa kwamandla kagesi ukukhanya kanye nengxenye yokushisa.Abantu bangakuzwa kahle ukushisa okukhishwa isibani se-incandescent uma beseduze kakhulu..

Amandla kagesi e-LED aguqulwa abe amandla okukhanya, futhi imisebe yokushisa ekhiqizwayo mincane kakhulu.Iningi lekhono liguqulwa ngokuqondile libe amandla okukhanya.Ngaphezu kwalokho, amandla ezibani ezijwayelekile aphansi.Ngokuhambisana nesakhiwo sokukhipha ukushisa, imisebe yokushisa yemithombo yokukhanya ebandayo ye-LED ingcono kunaleyo yezibani ze-incandescent.

Umehluko wesithathu ukuthi amalambu akhishwa yilaba bobabili ahlukene.Ukukhanya okukhishwa isibani se-incandescent kungukukhanya okunemibala egcwele, kodwa isilinganiso sokwakheka kwezibani ezinemibala ehlukahlukene sinqunywa into ekhanyayo nezinga lokushisa.Isilinganiso esingalinganisi sibangela ukubunjwa kombala kokukhanya, ngakho umbala wento engaphansi kwesibani se-incandescent awuwona owangempela ngokwanele.

I-LED ingumthombo wokukhanya okuluhlaza.Isibani se-LED sishayelwa yi-DC, akukho stroboscopic, akukho zingxenye ze-infrared ne-ultraviolet, akukho ukungcoliswa kwemisebe, ukunikezwa kombala okuphakeme ngokuqhathaniswa nokuqondisa okukhanyayo okuqinile.

Akukhona lokho kuphela, ukukhanya kwe-LED kunokusebenza okuhle kokufiphala, alikho iphutha elibonakalayo elenzekayo lapho izinga lokushisa lombala lishintsha, futhi umthombo wokukhanya obandayo unesizukulwane sokushisa esiphansi futhi ungathinteka ngokuphepha.Inganikeza indawo yokukhanyisa enethezekile futhi enhle Ingumthombo wokukhanya onempilo ovikela amehlo futhi evumelana nemvelo ukuhlangabezana nezidingo zempilo yabantu.
