LED Multi-layer Electronic Sirens kunye nezithethi Ulwazi oluSiseko
LED multi-layer Electronic Sirens kunye Izithethi ulwazi olusisiseko
I-1: I-LED ye-multi-layer Electronic Sirens kunye neZithethi, kubandakanywa neshumi elinesibini okanye ngaphezulu kwee-chips ze-LED, zihlala zidibene kunye.Ukukhanya okuqaqambileyo kwetshiphu nganye kumiselwa bubungakanani bangoku odlula kuyo.Njengomphumo woqhagamshelo loluhlu, i-chip nganye ye-LED ngaphakathi kwe-LED iya ngokuzenzekelayo ngokusebenzisa okwangoku, kodwa i-voltage kwi-chip nganye yahlukile.Ukuhla kwamandla ombane angaphambili kwe-LED ngokuqhelekileyo yi-3.4V, kodwa iyahluka phakathi kwe-2.8V kunye ne-4.2V.I-LED inokuhlelwa ukuba inciphise uluhlu lokuguquguquka kwamandla ombane, kodwa oku kuya kwandisa iindleko, kwaye ukuhla kwamandla ombane kuya kutshintsha kunye nobushushu kunye nokusetyenziswa kwexesha.Ukubonelela ngokuphuma kokukhanya okuhambelanayo, i-LED kufuneka iqhutywe ngokulawulwa ngokungqongqo kwi-high-effective current current.Njengenye indlela yezibane ze-incandescent ze-LED, ukunikezelwa kwamandla kufuneka kuhlanganiswe kwizindlu zesibane.
I-2: I-LED edibeneyo ye-Sirens ye-Electronic kunye neZithethi ziquka i-drive circuit, i-cluster ye-LED kwaye inokubonelela ngomqhubi kunye ne-chip ye-LED yokukhusela oomatshini kunye nokupholisa kwegobolondo.
3: Iimfuno zomqhubi we-LED zingqongqo kakhulu.Kufuneka isebenzise amandla kwaye ihlangabezane ne-EMI engqongqo kunye neenkcukacha zezinto zamandla kwaye inokumelana ngokukhuselekileyo neemeko ezahlukeneyo zeempazamo.Enye yezona mfuno zinzima kukuba nomsebenzi wokufiphala.Ngenxa yokungahambelani phakathi kweempawu zesibane se-LED kunye nomlawuli we-dimming eyenzelwe izibane ze-incandescent, kunokwenzeka ukuba kubangele ukusebenza kakubi.Ingxaki inokuba isantya sokuqalisa sicotha, siqhwanyaza, siqhwanyaza, iiSirens ze-Electronic kunye nezithethi zokukhanya okungalinganiyo, okanye ukuqhwanyaza xa ukukhanya kulungelelaniswa.Ukongezelela, kukho ukungahambelani ekusebenzeni kweyunithi nganye kunye nezibane ze-LED zikhuphe ingxolo evakalayo kunye neminye imiba.Ezi meko ezimbi zidla ngokubangelwa ukubangela ubuxoki okanye ukuvala kwangaphambi kwexesha lomlawuli kunye nokulawulwa okungafanelekanga kwe-LED yangoku kunye nezinye izinto.
I-4: Okwangoku, iimveliso ze-LED zibanga ukuba zine-gap enkulu kunye nobomi benkonzo yangempela.Kwimeko yokuqokelela okulinganiselweyo kweteknoloji yoyilo lwesekethe yokuqhuba, kunye novavanyo lobomi bemveliso ukulinganisa ubomi bokwenyani bendlela, okunokuthi kubangele iimpazamo.Nangona ukuzinza komgca wokuqhuba kuya kuchaphazela ngokuthe ngqo ukuzinza okupheleleyo kwemveliso.
