Indlela ama-LED athintwa ngayo Amazinga Okushisa Okubandayo Nakushisa
Ama-LED asebenza kanjani emazingeni okushisa abandayo
Enye yezinzuzo ezidume kakhulu zokukhanyisa kwe-LED ukuthi isebenza kahle emazingeni okushisa aphansi. Isizathu esikhulu salokhu yingoba incike kumadrayivu kagesi ukuze isebenze.
Iqiniso liwukuthi ama-LED empeleni ayachuma emazingeni okushisa aphansi.
Njengoba ama-LED eyimithombo yokukhanya ye-semiconductor, akhipha ukukhanya lapho okwamanje kugeleza kuwo, ngakho-ke awathintwa izinga lokushisa lendawo ebandayo futhi angavulwa ngokushesha.
Ngaphezu kwalokho, ngenxa yokuthi ukucindezeleka okushisayo (ukushintsha kwezinga lokushisa) okubekwe ku-diode nomshayeli kuncane, ama-LED asebenza kangcono emazingeni okushisa aphansi. Eqinisweni, ucwaningo luye lwabonisa ukuthi lapho i-LED ifakwe endaweni ebandayo, izinga layo lokuwohloka lizoncishiswa futhi ukuphuma kwe-lumen kuzokwanda.
Isebenza kanjani i-LED emazingeni okushisa aphezulu
Ngenkathi ama-LED ethulwa okokuqala emakethe, ayenendlu yesitayela sebhokisi lezicathulo futhi ayekwazi ukushisisa ngokushesha ngenxa yokuntuleka komoya. Ukuze uvimbele lokhu kungenzeki, abakhiqizi sebeqalile ukufaka abalandeli ezibanini ze-LED, kodwa lokhu kuzodala kuphela ukwehluleka kwemishini.
Isizukulwane esisha sama-LED sinosinki wokushisa ukusiza ukuvimbela ukwehla kwe-lumen okuhlobene nokushisa. Bahambisa ukushisa okweqile futhi bawagcine kude nama-LED nabashayeli. Ezinye izibani zifaka isekethe yesinxephezelo elungisa ukugeleza kwamanje ku-LED ukuze kuqinisekiswe ukuphuma kokukhanya okuqhubekayo kumazinga okushisa ahlukene.
Kodwa-ke, njengamanye amadivaysi e-elekthronikhi, ama-LED ajwayele ukusebenza kabi uma esebenza emazingeni okushisa angaphezulu kwalindelekile. Endaweni yokushisa okuphezulu kwesikhathi eside, i-LED ingase isebenze ngokweqile, okungase ifinyeze ubude bayo bempilo (L70). Izinga lokushisa eliphakeme le-ambient lizoholela ekushiseni okuphezulu kwe-junction, okuzokhuphula izinga lokuwohloka kwezingxenye ze-junction ye-LED. Lokhu kubangela ukuthi ukuphuma kwe-lumen yesibani se-LED kwehle kakhulu ngesivinini esisheshayo kunasemazingeni okushisa aphansi.
Kodwa-ke, ngenxa yokushisa kwe-ambient, izinga lapho impilo ye-LED iqala ukwehla kakhulu ayivamile. Kuphela uma wazi ukuthi izinto zakho zokukhanyisa zizochayeka emazingeni okushisa aphezulu isikhathi eside, kuyadingeka ukuthi ufunde ukuthi zingathinta kanjani ukukhetha kwakho kokukhanyisa.
