Dab tsi yog cov yam ntxwv ntawm LED teeb pom kev zoo?
Kuv ntseeg tias txhua tus paub txog LED teeb pom kev zoo. Niaj hnub no txoj kev, txoj kev, tsev, thiab lwm yam yog tag nrho cov teeb LED, tab sis koj paub ntau npaum li cas txog LED teeb? Dab tsi yog nws cov yam ntxwv tsis paub thiab qhov zoo?
1. LED teeb pom kev zoo yog dab tsi?
LED teeb pom kev zoo yog lub teeb -emitting diode teeb pom kev zoo, uas yog ib qho khoom siv hluav taws xob semiconductor -lub xeev lub teeb- emitting device. Nws siv cov khoom siv semiconductor nti ua cov khoom siv luminescent, nyob rau hauv cov khoom siv semiconductor los ntawm kev sib koom ua ke ntawm cov nqa khoom, lub zog ntau dhau raug tso tawm kom ua rau photon emissions, uas ncaj qha emits liab, daj, xiav, thiab ntsuab teeb. Rau lub hauv paus no, siv lub hauv paus ntsiab lus ntawm peb lub ntsiab xim, Ntxiv phosphor hmoov tuaj yeem tawm lub teeb ntawm txhua yam xim xws li liab, daj, xiav, ntsuab, xiav, ntsuab, txiv kab ntxwv, ntshav, thiab dawb. LED teeb yog cov teeb pom kev zoo uas siv LEDs ua lub teeb ci.
2. Dab tsi yog cov yam ntxwv ntawm LED teeb pom kev zoo?
1. Txwv tsis pub dhau
(1) Tso cai siv hluav taws xob Pm: tus nqi siab tshaj plaws ntawm cov khoom ntawm DC rau pem hauv ntej voltage thiab tam sim no ntws los ntawm nws uas tau tso cai siv rau ob hnub ntawm LED. Yog tias tus nqi no dhau lawm, LED yuav sov thiab puas.
(2) Qhov siab tshaj plaws rau pem hauv ntej DC tam sim no IFm: qhov siab tshaj plaws tso cai rau pem hauv ntej DC tam sim no. Tshaj qhov nqi no tuaj yeem ua rau lub diode puas.
(3) Qhov siab tshaj qhov rov qab voltage VRm: qhov siab tshaj plaws tso cai rov qab voltage. Tshaj qhov nqi no, lub teeb -emitting diode yuav raug puas tsuaj los ntawm kev tawg.
(4) Ib puag ncig ua haujlwm sab saum toj: Qhov ntsuas kub ib puag ncig uas lub teeb -emitting diode tuaj yeem ua haujlwm ib txwm. Hauv qab lossis siab dua qhov ntsuas kub no, lub teeb -emitting diode yuav tsis ua haujlwm zoo, thiab kev ua haujlwm yuav raug txo kom tsawg.
2. Kev ntseeg tau ntawm LED teeb pom kev zoo
Ib qho laj thawj tseem ceeb rau lub neej qis ntawm LED tsav lub zog yog qhov tsis muaj lub neej ntawm txhuas electrolytic capacitors xav tau rau kev tsav lub zog. Nws tau qaug zog thiab lub neej luv luv heev, feem ntau tsuas yog li 5,000 teev ua haujlwm. Lub neej ntawm lub teeb ci LED yog 50, 000 teev, yog li lub neej ua haujlwm ntawm aluminium electrolytic capacitor tau dhau los ua lub neej luv luv ntawm lub neej ntawm LED tsav fais fab mov.
3. Ntsuab zog txuag thiab kev tiv thaiv ib puag ncig
Nws tsis muaj mercury, txhuas thiab lwm yam hlau hnyav uas ua rau ib puag ncig tsis zoo, thiab tsis tsim cov kab hluav taws xob ultraviolet thaum emitting lub teeb, yog li LED teeb pom kev zoo yuav tsis muaj ntau yoov tshaj cum nyob ib ncig ntawm lub teeb pom kev zoo li cov teeb ci, ua rau thaj chaw huv thiab huv si; lub plhaub hlau yog tas li Lub zog tshiab-tsav tsim ua kom cov khoom siv hloov hluav taws xob rau hauv lub teeb nrog kev ua haujlwm siab.
Shenzhen Benwei Teeb pom kev zoo Technology Co., Ltd yog cov chaw tsim khoom lag luam hauv kev tsim cov khoom siv teeb pom kev zoo, Peb cov khoom tseem ceeb T8 T5 LED Tube, LED Loj Hlob Teeb, Nqaij qaib LED Teeb, Tri- pov thawj LED Teeb, LED Dej nyab lub teeb, LED vaj huam sib luag , LED Stadium Teeb, LED High Bay, LED Classing Room Teeb, Yog tias koj xav yuav cov khoom lag luam zoo - LED teeb pom kev zoo lossis muaj ntau yam hauv - kev nkag siab tob ntawm daim ntawv thov ntawm LED teeb pom kev zoo, thov tiv tauj xa peb nug.
