Qhov sib txawv ntawm coj tsav tsheb thiab ballast
LED Tsav Tsheb (LED Tsav Tsheb) yog hais txog lub zog hloov hluav taws xob hluav taws xob uas tsav LED teeb lossis LED module cov khoom ua haujlwm ib txwm. Vim yog cov yam ntxwv ntawm LED PN kev sib tshuam, qhov hluav taws xob thiab qhov hloov pauv tam sim no ntawm lub zog hluav taws xob nws tuaj yeem hloov kho kom nqaim heev. Ib qho kev sib txawv me ntsis yuav tsis teeb lub LED lossis txo qis kev ua haujlwm ntawm lub teeb ci, lossis ua rau lub neej ua haujlwm luv lossis tseem hlawv cov nti. Cov khoom siv hluav taws xob tam sim no thiab cov roj teeb uas siv hluav taws xob tsis haum rau cov khoom siv hluav taws xob ncaj qha. LED tsav tsheb yog cov khoom siv hluav taws xob zoo li no tuaj yeem tsav LEDs ua haujlwm nyob rau hauv qhov zoo tshaj plaws voltage lossis tam sim no.
Ballast resistor yog ib qho cuab yeej uas txwv tam sim no thiab ua kom muaj hluav taws xob siab tam sim no ntawm cov teeb fluorescent. Nws yog ua los ntawm enameled hlau qhwv ib ncig ntawm ib tug hlau core ua los ntawm silicon steel. Xws li ib lub kauj nrog cov tub ntxhais hlau tuaj yeem qhib / tawm hauv ib qho instant. Thaum lub high voltage yog generated los ntawm tus kheej-induction, nws yog siv rau cov electrodes (filaments) ntawm ob qho tag nrho ntawm lub fluorescent raj. Qhov kev txiav txim no yog ua alternated. Thaum lub oob khab (npuas dhia) raug kaw, lub filament ntawm lub teeb lub raj yog txwv kom ua cua sov los ntawm ballast; Thaum lub oob khab qhib, lub ballast yuav self-inductively tsim high voltage thiab ntxiv Nyob rau ntawm lub filaments ntawm ob hnub ntawm lub teeb raj, lub filament emits electrons mus bombard lub fluorescent hmoov rau ntawm lub raj phab ntsa, thiab lub starter yog rov qab mus rau thiab tawm ob peb zaug, thiab qhov kev txiav txim no yuav rov ua dua ob peb zaug, yog li qhib lub teeb lub raj. Thaum lub teeb emitting ib txwm, lub sab hauv kuj yuav me me, thiab lub oob khab yog ib txwm khaws cia nyob rau hauv ib tug qhib lub xeev, kom cov tam sim no ntws los ntawm lub teeb thiab ballast stably, thiaj li hais tias lub teeb yuav emit lub teeb ib txwm. Txij li thaum lub ballast ib txwm muaj tam sim no ntws los ntawm lub teeb fluorescent, nws yooj yim los tsim kev co thiab ua kom sov. Yog li ntawd, lub teeb fluorescent nrog lub ballast, tshwj xeeb tshaj yog thaum qhov zoo ntawm lub ballast tsis zoo, yuav tsim ntau lub suab. Thaum lub sij hawm, nws yog ib qho yooj yim mus hlawv. Ballasts muab faib ua hluav taws xob ballasts thiab magnetic ballasts.
