LED Multi-layer Electronic Sirens Thiab Speakers Basic Knowledge
LED multi-layer Electronic Sirens thiab Speakers yooj yim kev paub
1: Ib qho LED ntau txheej Electronic Sirens thiab hais lus, suav nrog lub kaum os lossis ntau dua LED chips, lawv feem ntau txuas ua ke.Lub luminous brightness ntawm txhua nti yog txiav txim siab los ntawm qhov loj ntawm qhov tam sim no dhau los ntawm nws.Raws li qhov tshwm sim ntawm kev sib txuas ntawm cov koob, txhua LED nti hauv LED yuav cia li los ntawm tib lub tam sim no, tab sis qhov voltage ntawm txhua nti sib txawv.Lub zog poob rau pem hauv ntej ntawm LED yog feem ntau 3.4V, tab sis txawv ntawm 2.8V thiab 4.2V.LED tuaj yeem raug cais tawm kom txwv tsis pub muaj qhov sib txawv ntawm qhov sib txawv, tab sis qhov no yuav ua rau tus nqi nce ntxiv, thiab qhov kev poob qis rau pem hauv ntej tseem yuav hloov nrog qhov kub thiab txias thiab siv sijhawm.Txhawm rau muab cov teeb pom kev zoo sib xws, LED yuav tsum tau tsav los ntawm kev tswj hwm nruj kom muaj txiaj ntsig zoo tam sim no.Raws li ib qho kev xaiv rau incandescent LED teeb, lub hwj huam mov yuav tsum tau muab tso rau hauv lub teeb vaj tsev.
2: Kev sib xyaw ua ke LED Electronic Sirens thiab Speakers muaj xws li tsav Circuit Court, LED pawg thiab tseem tuaj yeem muab tus tsav tsheb thiab LED nti rau kev tiv thaiv thiab cua txias ntawm lub plhaub.
3: LED tsav tsheb yuav tsum nruj heev.Nws yuav tsum muaj lub zog txuag thiab yuav tsum ua kom tau raws li EMI nruj thiab lub zog muaj zog tshwj xeeb thiab tuaj yeem tiv taus ntau yam kev ua txhaum.Ib qho ntawm cov kev xav tau nyuaj tshaj plaws yog kom muaj lub zog dimming.Vim qhov tsis sib xws ntawm cov yam ntxwv ntawm LED teeb thiab lub teeb pom kev zoo tsim los rau cov teeb pom kev zoo, nws yuav ua rau kev ua haujlwm tsis zoo.Qhov teeb meem tuaj yeem yog qhov pib nrawm nrawm, blinking, Electronic Sirens thiab hais lus tsis sib xws, lossis blinking thaum lub teeb ci raug kho.Tsis tas li ntawd, muaj qhov tsis sib xws hauv kev ua haujlwm ntawm txhua chav tsev thiab LED teeb tawm suab nrov thiab lwm yam teeb meem.Cov xwm txheej tsis zoo no feem ntau yog tshwm sim los ntawm qhov tsis tseeb tshwm sim los yog kev kaw ntxov ntxov ntawm tus maub los thiab kev tswj tsis raug ntawm LED tam sim no thiab lwm yam.
4: Tam sim no, LED cov khoom lag luam thov kom muaj qhov sib txawv ntau dua nrog lub neej ua haujlwm tiag tiag.Nyob rau hauv cov ntaub ntawv ntawm tsawg tsub zuj zuj ntawm tsav Circuit Court tsim tshuab, nrog rau kev soj ntsuam ntawm cov khoom lub neej los ntsuas lub neej tiag tiag ntawm txoj kev, yuav ua rau yuam kev.Thaum qhov kev ruaj ntseg ntawm cov kab tsav yuav cuam tshuam ncaj qha rau tag nrho kev ruaj ntseg ntawm cov khoom.
