I-backlight ye-LCD yesikrini esikhulu kanye nokukhanya okuvamile kukhuthaza ukukhula okusheshayo

Ngonyaka wezi-2015 nowezi-2016, imali engenayo yemboni yokukhanyisa yesimo esiqinile iye yagcina izinga lokukhula elilinganiselwe ledijithi eyodwa, kodwa ngo-2017 imboni kulindeleke ukuthi ikhuthaze izinga lokukhula kwemali engenayo ye-LED ukuze ifinyelele amadijithi amabili.

I-iSuppli ibikezela ukuthi inani eliphelele lemakethe ye-LED ngo-2017 lizokhula cishe ngo-13.7%, futhi izinga lokukhula lonyaka elihlanganisiwe lika-2016-2012 lizoba cishe ku-14.6%, futhi lizofinyelela ku-12.3 bhiliyoni amadola aseMelika ngo-2012. Ngo-2015 no-2016, i Imakethe ye-LED yomhlaba wonke inyuke ngo-2.1% no-8.7% ngokulandelana.

Lezi zinombolo zifaka phakathi yonke idivayisi yokukhweza kwendawo (SMD) kanye nezibani ze-LED zephakheji le- through-hole kanye nama-LED wesibonisi samagama nezinombolo-okuhlanganisa ukukhanya okujwayelekile, ukukhanya okuphezulu (HB) nama-LED wokukhanya okuphezulu kakhulu (UHB).

Ingxenye enkulu yokukhula okulindelekile okukhulunywe ngenhla izovela ekukhanyeni okuphezulu kakhulu kanye nama-LED anokukhanya okuphezulu asetshenziswa ezinhlelweni zokukhanyisa.Ngonyaka wezi-2012, ama-LED agqama kakhulu azokubalela cishe u-31% wesamba senzuzo ye-LED, ephakeme kakhulu kunama-4% ngo-2015.

Umshayeli obalulekile wokukhula kwemakethe

“Esigabeni esisha sokukhula kwe-LED, imakethe iyaqhubeka nokuba nesidingo esinamandla sokukhanyisa isimo esiqinile sezinkinobho zangemuva nezibonisi zedivayisi yeselula.Lesi yisici esiyinhloko esikhuthaza ukukhula kwemakethe ye-LED,” kusho uDkt. Jagdish Rebello, umqondisi nomhlaziyi oyinhloko we-iSuppli.“Ukukhanyiswa kwezimoto ngaphakathi, kanye nokukhanyiswa kwama-LCD anesikrini esikhulu sama-TV namalaptop, lezi zimakethe ezisafufusa zizophinde zikhuthaze ukukhula kwemboni ye-LED.Ngaphezu kwalokho, ukuthuthukiswa okuqhubekayo kobuchwepheshe bokukhanyisa okuqinile kuzovumela ama-LED ukuthi athole izinhlelo zokusebenza ezintsha ekukhanyisweni kokuhlobisa kanye nezimakethe zokukhanyisa zezakhiwo.Indawo yezobuciko bokulwa.”

I-backlight ye-LCD isewuhlelo lokusebenza oluyinhloko lwe-LED

Muva nje, izibonisi ze-LCD zesikrini esincane nezibani zangemuva zenkinobho yedivayisi yeselula kuseyimakethe enkulu yohlelo lokusebenza eyodwa yama-LED.Ngo-2017, lezi zinhlelo zokusebenza zizoba ngaphezu kuka-25% wenzuzo yonke yemakethe ye-LED.

I-LED iqondise izibani zangemuva ze-LCD ezinkulu

Kusukela ngo-2017, ukukhanya kwangemuva kwama-LCD amakhulu njengezincwadi zokubhalela kanye nama-TV e-LCD anembile kuba uhlelo lokusebenza olulandelayo olubalulekile lwama-LED.

Izindleko ze-LCD backlight module (BLU) zisaphakeme kakhulu kune-CCFL BLU yendabuko, kodwa izindleko zalezi zibili zisondela ngokushesha.Futhi i-LED BLU inezinzuzo zokusebenza, njengokugqama okuphezulu, isikhathi sokuvula ngokushesha, i-gamut yombala obanzi, kanye nokungabikho kwe-mercury nakho kusiza ukuthi yamukelwe kuma-LCD.

Abanye abahlinzeki be-LED, abakhiqizi be-BLU, abakhiqizi bephaneli ye-LCD nabakhiqizi be-TV/nesibonisi se-OEM manje sebeqalile ukusebenzisa ama-LED njengokukhanya kwangemuva kwama-LCD wesikrini esikhulu.Ama-LCD anesikrini esikhulu asebenzisa i-LED BLU nawo aseqalile ukuthunyelwa kwezentengiso.

I-LED: Ikusasa lokukhanyisa okuvamile

Ukuthuthukiswa kwama-LED aguquguqukayo anekhono elikhanyayo elingaphezu kwe-100 lumens/watt kanye nokuvela kwemiklamo emisha kwenze ama-LED akwazi ukusebenza ngokushintshana kwamandla ngaphandle kwesidingo sama-inverters, ngaleyo ndlela kuphushele ama-LED eduze kwemakethe yezibani ezijwayelekile.

Ama-LED asetshenziswe ezinhlobonhlobo zezicelo zokukhanyisa zokuhlobisa zasendlini nangaphandle, futhi aqala ukugxila ezinhlelweni zokukhanyisa ezijwayelekile ezifana namathoshi, izibani zasengadini, nezibani zomgwaqo.Lokhu kusetshenziswa kuvula izimakethe zokukhanyisa kwe-LED emkhakheni wokukhanyisa kwasekhaya kanye nokwezinkampani.

Ngaphezu kwalokho, umhlaba uye waqinisa umthetho wokuvimbela ukusetshenziswa kwezibani ze-incandescent futhi ukhuthaze ukusetshenziswa kwemithombo yokukhanya eyonga amandla.Esikhathini esizayo esiseduze, amashubhu e-compact fluorescent (CFL) azozuza ezenzweni zomthetho ezivimbela ukusetshenziswa kwezibani ze-incandescent.

Kodwa ngokuhamba kwesikhathi, izinzuzo zokukhanya okuqinile zizokweqa umehluko wezindleko phakathi kwama-LED nama-CFL.Futhi njengoba ukusebenza kwe-LED kuqhubeka nokuba ngcono, umehluko wezindleko uzoncishiswa nakakhulu.

I-iSuppli ibikezela ukuthi ngo-2020 ama-LED ama-bulb azoqala ukusetshenziswa ekukhanyisweni okujwayelekile kokukhanyisa kwezindawo zokuhlala nezinkampani.
