Kev pom ntawm lub teeb fluorescent fais fab mov

Tus kheej, kuv xav tias cov kev coj ua no ntau lub sijhawm thiab lawv tsis muaj dab tsi tab sis qhov kawg. Tam sim no cia kuv nug dab tsi yog qhov zoo ntawm LED hla lub teeb ib txwm, thawj zaug, kev txuag hluav taws xob, lub sijhawm ntev thib ob, thiab tom qab ntawd tsis ntshai ntawm kev hloov pauv, txoj cai? Txawm li cas los xij, txoj hauv kev siab PF tam sim no siv tag nrho siv cov hav txwv yeem puv PF lub zog. Thawj txoj kev tsav tsheb yog 48 series, 6 parallel mus rau 24 series thiab 12 parallel. Hauv qhov no, qhov ua tau zoo yuav raug txo qis hauv 220V. Kwv yees li tsib feem pua ​​​​ntawm cov ntsiab lus, yog li LED fluorescent teeb lub zog, lub tshav kub yog siab dua, lub teeb hlaws yuav cuam tshuam me ntsis.

Muaj lwm qhov teeb meem, uas yog, kev xyaum ntawm 24 series thiab 12 parallel yuav ua rau cov xaim ntawm LED fluorescent teeb hlaws ua tsis xis nyob, thiab nws tsis yooj yim rau xaim. Hauv kuv lub tswv yim, txoj hauv kev zoo tshaj plaws yog siv 48 cov hlua, feem ntau yog vim muaj kev ua haujlwm siab, tsim hluav taws xob tsawg, thiab kev xaim yooj yim thiab tsis nyuaj.

Dab tsi' ntau ntxiv, tseem muaj cov neeg uas tau thov 24 sib npaug thiab 12 series. Txoj kev no tsuas yog tsim nyog rau cov khoom siv hluav taws xob cais tawm, thiab cov khoom siv hluav taws xob tsis sib cais tsis siv tau txhua. Qee cov neeg tsis paub' tsis paub lub hwj chim muab kev nkag siab zoo xav tias nws yog qhov zoo rau lawv kom ua tiav qhov tam sim no 600MA tso tawm los ntawm cov khoom siv hluav taws xob tsis sib cais. Qhov tseeb, nws tsis tau ua tib zoo sim nws hauv lub teeb raj ntawm nws tus kheej. Nws yog qhov txawv uas nws tsis kub.

Yog li, qhov tsawg-voltage thiab high-tam sim no yog tam sim no siv raws li LED fluorescent teeb lub zog mov, nws yog tiag tiag sim ua tsis muaj dab tsi.

Cov qauv yooj yim ntawm cov kauj ruam-down fais fab mov yog txuas cov inductor thiab cov load hauv series nrog high voltage ntawm 300V. Thaum lub tshuab hluav taws xob hloov mus rau thiab tawm, lub load paub qhov voltage qis dua 300V. Muaj ntau qhov tshwj xeeb hluav taws xob thiab ntau hauv online. Tam sim no 9910, muaj cov ICs tas li tam sim no ntawm kev ua lag luam yog qhov pib paub nrog cov hluav taws xob zoo li no. Tab sis hom hluav taws xob no yog thaum lub raj hloov pauv, tag nrho

LED lub teeb board tiav lawm, qhov no yuav tsum tau suav tias yog qhov phem tshaj plaws. Vim tias thaum lub raj hloov pauv, tag nrho 300V voltage yog siv rau lub teeb vaj huam sib luag. Keeb kwm, lub teeb vaj huam sib luag tsuas tuaj yeem tiv taus qhov hluav taws xob ntau tshaj li ib puas volts, tab sis tam sim no nws tau dhau los ua peb puas volts. Qhov no tshwm sim sai li sai tau thaum qhov no tshwm sim. LED yuav tsum tau hlawv. Yog li ntau tus neeg hais tias kev tsis sib cais tsis muaj kev nyab xeeb, qhov tseeb, nws txhais tau tias kev nqis tes ua, tsuas yog vim feem coob ntawm kev tsis sib cais feem ntau yog nqis nqis, yog li lawv xav tias kev puas tsuaj uas tsis nyob ib leeg yuav tsum rhuav tshem LED. Qhov tseeb, lwm yam ob qho yooj yim uas tsis yog kev sib cais Cov qauv thiab cov khoom siv hluav taws xob puas yuav tsis cuam tshuam rau LED.

Cov kauj ruam-down fais fab mov yuav tsum tau tsim nrog high voltage thiab tam sim no me me kom ua tau zoo. Cia kuv piav qhia, vim li cas? Vim tias qhov siab voltage thiab tsis tshua muaj tam sim no, lub mem tes dav ntawm lub raj hloov tam sim no tuaj yeem ua kom loj dua, kom lub ncov tam sim no me dua, thiab qhov poob ntawm inductance kuj me dua. Nws tuaj yeem paub los ntawm cov qauv hluav taws xob uas cov hluav taws xob tsis yooj yim rau kos, thiab nws yog qhov nyuaj rau qhov tshwj xeeb. Cia' mus rau. Yuav kom suav tau li casually, qhov kom zoo dua ntawm cov kauj ruam-down fais fab mov yog tias nws tsim nyog rau 220 high-voltage input, thiaj li hais tias qhov voltage ntawm lub hwj chim ntaus ntawv yog me me, thiab nws yog haum rau loj tam sim no tso zis, xws li 100MA. tam sim no, uas yooj yim dua thiab ua haujlwm zoo dua li ob txoj hauv kev tom kawg. Yuav tsum siab. Qhov kev ua tau zoo yog qhov siab, qhov poob rau inductor me me, tab sis qhov poob rau lub raj hloov pauv loj dua, vim tias txhua lub zog dhau los ntawm kev thauj khoom yuav tsum tau xa los ntawm lub raj xa mus, tab sis tsuas yog ib feem ntawm cov zis hluav taws xob dhau los. Lub inductor, xws li 300V input, 120V tso zis Rau lub puck-hom fais fab mov, tsuas yog 180V ib feem yuav tsum tau dhau los ntawm inductor, thiab 120V ib feem yog txuas ncaj qha mus rau lub load, yog li ntawd inductor poob yog me me, tab sis tag nrho cov. lub zog tso zis yuav tsum dhau los ntawm lub raj hloov.

Cov khoom siv hluav taws xob tsis raug cais tawm yog cov qauv siv hluav taws xob uas siv tam sim no, suav txog yuav luag 90% ntawm cov khoom siv hluav taws xob fluorescent. Ntau tus neeg xav tias cov khoom siv hluav taws xob tsis sib cais tsuas muaj ib hom kev nqis tes ua. Thaum twg lawv tham txog kev tsis nyob ib leeg, lawv xav txog hom kev nqis tes ua, thiab lawv xav tias lawv tsis muaj kev nyab xeeb rau lub teeb (xws li kev puas tsuaj rau lub hwj chim). Qhov tseeb, tsis yog tsuas yog ib hom kev nqis tes ua, tab sis kuj tseem muaj ob lub qauv yooj yim, uas yog boost thiab buck-boost, uas yog BOOSTANDBUCK-BOOST, txawm tias tom kawg ob lub zog siv hluav taws xob puas. Yuav tsis cuam tshuam cov txiaj ntsig ntawm LED. Cov kauj ruam-down fais fab mov kuj muaj nws qhov zoo. Nws yog haum rau 220, tab sis tsis yog rau 110, vim hais tias 110V yog Ameslikas tsis tshua muaj voltage, thiab nws yuav txawm qis dua thaum nws txo, kom cov zis tam sim no loj, qhov voltage yog tsawg, thiab cov efficiency tsis siab dhau. . Kauj ruam-down 220V AC, txog peb puas volts tom qab kho thiab lim. Tom qab qhov hluav taws xob txo qis, qhov hluav taws xob feem ntau raug txo kom txog li 150V DC, kom cov zis hluav taws xob siab thiab qis tam sim no tuaj yeem ua tiav, thiab qhov ua tau zoo tuaj yeem siab dua. Feem ntau, MOS yog siv los ua lub raj hloov thiab lub zog ntawm cov lus qhia no. Kuv qhov kev paub yog tias nws tuaj yeem nyob ze li 90%, thiab nws nyuaj rau nce mus. Yog vim li cas yooj yim, cov nti feem ntau nws tus kheej puas tsuaj los ntawm 0.5W mus rau 1W, thaum lub fluorescent raj fais fab mov tsuas yog hais txog 10W. Yog li nws tsis tuaj yeem mus ntxiv. Niaj hnub no, lub zog efficiency yog qhov tseeb heev. Ntau tus neeg hais tias nws tuaj yeem' tsis ncav cuag nws txhua.

LED fluorescent teeb puas yuav hlawv? Nws yog ib txwm muaj rau qee cov neeg hais tias qhov ua tau zoo ntawm 3W fais fab mov yog 85%, thiab nws tseem raug cais tawm. Cia kuv qhia rau txhua tus neeg tias txawm tias nyob rau hauv ntau zaus hopping hom, tsis muaj kev siv hluav taws xob yog qhov tsawg tshaj plaws, uas yog 0.3W. Dab tsi ntxiv yog qhov tso zis ntawm 3W tsis tshua muaj hluav taws xob, uas tuaj yeem ncav cuag 85%. Qhov tseeb, 70% suav tias yog qhov zoo heev. Txawm li cas los xij, tam sim no Ntau tus neeg khav theeb txog tsis ua cov ntawv sau thiab tuaj yeem dag tus neeg ua haujlwm, tab sis tam sim no, tsis muaj coob tus neeg uas ua LED nkag siab txog lub hwj chim.

Kuv tau hais tias kom muaj kev ua haujlwm siab, ua ntej ntawm tag nrho cov, nws yuav tsum tsis txhob raug cais tawm, thiab tom qab ntawd cov khoom siv hluav taws xob yuav tsum muaj qhov hluav taws xob siab thiab tsis tshua muaj tam sim no, uas tuaj yeem txuag tau qhov tsis zoo ntawm cov khoom siv hluav taws xob, yog li zoo li no.

Qhov kev poob tseem ceeb ntawm LED fais fab mov, ib qho yog kev siv tus kheej ntawm cov nti, qhov kev poob no feem ntau yog ob peb feem kaum ntawm W rau ib W, thiab lwm qhov yog kev hloov pauv. Siv MOS ua lub raj hloov pauv tuaj yeem txo qhov kev poob no. Siv lub triode hloov pauv poob Nws' loj dua. Yog li sim tsis txhob siv lub triode. Kuj tseem muaj cov khoom siv hluav taws xob me me, nws yog qhov zoo tshaj plaws kom tsis txhob txuag ntau dhau, tsis txhob siv RCC, vim tias RCC cov tuam txhab fais fab tsis zoo, qhov tseeb, cov chips kuj pheej yig tam sim no, zoo tib yam.

Hloov fais fab mov chips thiab kev sib xyaw MOS hlab tsuas yog ob yuan ntawm feem ntau. Tsis tas yuav txuag me ntsis. RCC tsuas yog txuag me ntsis ntawm cov khoom siv. Qhov tseeb, tus nqi ntawm kev ua thiab kho yog siab dua. Thaum kawg, qhov nce tsis tsim nyog rau qhov poob.

Decompose ob txoj kev tswj tam sim no

Qhov kuv xav hais hauv qab no yog ob hom kev tswj tam sim no ntawm kev hloov hluav taws xob, ua rau ob txoj hauv kev. Ob txoj hauv kev sib txawv heev ntawm cov ntsiab lus, kev siv cuab yeej siv, lossis kev ua haujlwm.

Cia kuv tham txog lub hauv paus ntsiab lus ua ntej. Thawj hom yog sawv cev los ntawm qhov tam sim no tsis tu ncua tam sim no LED nplooj siab IC, feem ntau xws li 9910 series, AMC7150, thiab tag nrho cov hom ntawm LED tsis tu ncua tam sim no tsav ICs yog hom no, thiab hu nws tam sim no IC hom. Tab sis kuv xav tias qhov no hu ua IC tam sim no tsis ua haujlwm zoo rau qhov tsis tu ncua tam sim no. Lub hauv paus ntsiab lus tswj yog qhov yooj yim. Nws yog los teeb tsa qhov pib tam sim no nyob rau hauv thawj sab ntawm lub hwj huam mov. Thaum thawj sab MOS qhib, lub inductor tam sim no yuav nce linearly. Thaum nws nce mus rau ib qho nqi, Thaum qhov chaw pib mus txog, qhov tam sim no raug muab tua, thiab qhov kev coj ua tau tshwm sim los ntawm qhov cuam tshuam ntawm lub voj voog tom ntej. Qhov tseeb, qhov tam sim no tsis tu ncua yuav tsum yog hom kev txwv tam sim no. Peb paub tias thaum lub inductance sib txawv, cov duab ntawm cov thawj tam sim no txawv. Txawm hais tias muaj tus nqi siab tib yam, qhov nruab nrab tam sim no tus nqi sib txawv. Yog li ntawd, thaum cov khoom siv hluav taws xob zoo li no feem ntau tsim tawm, qhov sib xws ntawm qhov tam sim no qhov loj me tsis tswj tau zoo. Kuj tseem muaj qhov tshwj xeeb ntawm hom kev siv fais fab no. Feem ntau, cov zis tam sim no yog trapezoidal, uas yog, hloov pauv tam sim no, thiab cov zis feem ntau smoothed yam tsis muaj electrolysis. Qhov no kuj yog ib qho teeb meem. Yog tias tus nqi siab tshaj tam sim no loj dhau, nws yuav cuam tshuam rau LED. Yog hais tias qhov tso zis theem ntawm lub hwj chim mov tsis muaj hom fais fab mov uas siv electrolysis kom du tam sim no, nws yeej belongs rau hom no. Ntawd yog, los txiav txim seb nws puas yog hom kev tswj hwm no, nws nyob ntawm seb cov zis puas txuas nrog electrolytic filtering. Kuv tau siv los hu rau qhov tam sim no tsis tu ncua tam sim no tsis raug tam sim no, vim tias nws cov ntsiab lus yog ib hom kev txwv tam sim no, tsis yog tus nqi tam sim no tau los ntawm kev sib piv op amp.

Txoj kev thib ob tsis tu ncua tam sim no yuav tsum raug hu ua hom hloov hluav taws xob hloov. Txoj kev tswj hwm no zoo ib yam li qhov kev tswj xyuas qhov hluav taws xob tas li ntawm lub zog hloov hluav taws xob. Txhua leej txhua tus paub siv TL431 raws li qhov tsis tu ncua, vim tias muaj 2.5 volt siv sab hauv, thiab tom qab ntawd siv txoj kev faib cov resistor. Thaum qhov hluav taws xob tso zis ntau dua los yog qis dua, qhov sib piv voltage yog tsim thiab nthuav los tswj PWM teeb liab, yog li txoj kev tswj hwm no tuaj yeem tswj qhov hluav taws xob tau zoo heev. Hom kev tswj no yuav tsum muaj kev siv thiab op amp. Yog hais tias qhov kev siv yog txaus txaus thiab lub amplifier magnification loj txaus, ces lub teeb yog qhov tseeb. Ib yam li ntawd, txhawm rau ua qhov tam sim no, koj xav tau qhov kev siv tam sim no, ib qho op amp, thiab siv qhov kev tiv thaiv dhau tam sim no raws li lub teeb liab, thiab tom qab ntawd siv cov teeb liab no los ua kom muaj zog los tswj PWM. Hmoov tsis zoo, nws tsis yooj yim los nrhiav qhov tseeb siv lub teeb liab. Feem ntau siv yog triodes. Qhov no yog siv raws li kev siv. Qhov kub drift yog loj, thiab tus nqi conduction ntawm li 1V ntawm lub diode yuav siv tau raws li ib tug siv. Hluav taws xob yog qhov nyuaj. Tab sis hom kev siv hluav taws xob tas li tam sim no, qhov tseeb qhov tseeb tam sim no tseem yooj yim dua los tswj. Rau qhov tam sim no tswj los ntawm hom no, cov zis yuav tsum yog electrolytic filtering, yog li lub zog tso zis yog du DC, tsis pulsating. Yog tias nws yog pulsating, nws tsis tuaj yeem ua qauv. Yog li txhawm rau txiav txim siab seb qhov twg tsuas yog yuav tsum tau saib seb cov zis puas muaj electrolysis lossis tsis.

Ob hom kev tswj tam sim no tsis tu ncua txiav txim siab siv ob hom khoom siv sib txawv. Ib qho yog tias ob qho khoom siv hluav taws xob siv sib txawv, lawv qhov kev ua tau zoo sib txawv, thiab lawv cov nqi kuj txawv. Lub zog hluav taws xob LED ua los ntawm kev tswj xyuas tam sim no tsis tu ncua IC sawv cev los ntawm 9910 series yog qhov tam sim no txwv thiab kev tswj tau yooj yim. Hais lus nruj me ntsis, nws tsis yog nyob rau hauv lub ntsiab hom ntawm switching fais fab mov tswj. Lub hom phiaj tseem ceeb ntawm kev hloov fais fab mov tswj yuav tsum muaj Benchmarks thiab op amps. Tab sis hom IC no tsuas yog siv tau rau LEDs, thiab nws nyuaj rau siv rau lwm yam, vim tias LEDs xav tau qis heev. Tab sis vim nws tsuas yog siv rau LEDs, tus nqi siab dua tam sim no. Yeej, nws yog ua los ntawm 9910 ntxiv rau MOS raj, thiab cov zis yog electroless. Feem ntau, kuv xav tias ntau tus neeg siv I-shaped inductance los hloov cov inductance. Hom kev siv fais fab no, feem ntau pom nyob rau hauv cov ntaub ntawv nti ntawm cov chaw tsim khoom, yog ib hom kev nqis tes ua. Kuv yeej' tsis hais ntau, muaj ntau tus neeg zoo ntawm qhov no dua kuv.

Ob yog sawv cev los ntawm kuv, uas yog, tus neeg tsav tsheb tam sim no ntawm kev hloov hluav taws xob tswj hom. Hom nti no siv cov khoom siv hluav taws xob hloov pauv zoo tib yam li cov khoom siv hloov pauv tseem ceeb. Muaj ntau cov chips xws li PI's TNY series, TOP series, ST's VIPER12, VIPER22, Fairchild' s FSD200, thiab lwm yam, thiab txawm tias tsuas yog siv cov transistors lossis MOS raj. RCC, thiab lwm yam, tuaj yeem ua tau. Qhov kom zoo dua yog tus nqi qis thiab kev ntseeg tau zoo. Vim tias cov khoom siv hluav taws xob hloov pauv zoo tib yam tsis yog cov nqi zoo xwb, tab sis kuj yog cov khoom lag luam classic uas tau siv dav. Qhov tseeb, ICs zoo li no feem ntau koom nrog MOS hlab, uas yooj yim dua li 9910 ntxiv rau MOS, tab sis txoj kev tswj hwm yog qhov nyuaj dua thiab yuav tsum muaj cov cuab yeej tswj xyuas sab nraud, uas tuaj yeem yog triode lossis op amp. Cov khoom sib nqus tuaj yeem siv I-shaped inductors lossis high-frequency transformers nrog cov pa tawm.

Kuv nyiam siv transformers, vim hais tias txawm hais tias tus nqi ntawm inductance tsawg heev, kuv xav tias nws lub peev xwm thauj khoom tsis zoo, thiab nws kuj tsis yooj yim los kho cov inductance. Yog li kuv xav tias kev xaiv cov cuab yeej zoo dua yog qhov sib xyaw ua ke MOS hloov hluav taws xob muab hluav taws xob ntxiv rau lub tshuab hluav taws xob ntau zaus, uas yog qhov kev xaiv zoo tshaj plaws ntawm kev ua haujlwm thiab tus nqi. Tsis tas yuav siv ICs tam sim no, cov khoom zoo li no, thiab Tsis yooj yim rau siv thiab kim.

Thaum kawg, ib txoj hauv kev tseem ceeb tshaj plaws kom paub qhov txawv ntawm ob lub zog siv hluav taws xob no yog saib seb cov zis yog lim los ntawm electrolytic capacitors.

Hais txog qhov teeb meem ntawm lub zog hluav taws xob-txawm hais tias nws yog qhov tam sim no-txhim kho qhov tam sim no tswj fais fab mov lossis op amp tswj qhov hluav taws xob tas li tam sim no, qhov teeb meem ntawm lub hwj chim yuav tsum tau daws. Ntawd yog, thaum lub tshuab hluav taws xob hloov hluav taws xob ua haujlwm, nws xav tau qhov hluav taws xob DC ruaj khov rau lub zog ntawm lub nti, thiab qhov ua haujlwm tam sim no ntawm cov nti txawv ntawm ib qho MA mus rau ntau MAs. Muaj ib hom nti zoo li FSD200, NCP1012, thiab HV9910, hom nti no yog lub siab-voltage noj nws tus kheej, uas yooj yim rau siv, tab sis high-voltage noj ua rau IC cua sov nce, vim IC yuav tsum tau tiv taus txog 300V. Tam sim no ncaj qha, tsuav yog muaj me ntsis tam sim no, Txawm tias ib qho MA, muaj 0.3 watts ntawm kev puas tsuaj thiab noj. Feem ntau, cov khoom siv hluav taws xob LED tsuas yog kwv yees li kaum watts, thiab qhov poob ntawm ob peb feem kaum ntawm ib lub watt tuaj yeem txo qhov kev ua haujlwm ntawm lub zog los ntawm ob peb lub ntsiab lus. Kuj tseem muaj tus qauv QX9910. Nws siv lub resistor rub down kom tau lub zog. Nyob rau hauv txoj kev no, qhov poob yog nyob rau hauv qhov tsis kam, thiab nws yuav tsum poob li ob peb feem kaum ntawm ib watt. Kuj tseem muaj cov hlau nplaum sib txuas, uas yog, lub tshuab hloov pauv yog siv los ntxiv winding rau lub ntsiab fais fab kauj, ib yam li cov pab cuam winding ntawm flyback fais fab mov, kom tsis txhob poob lub zog ntawm ob peb feem kaum ntawm ib watt. Qhov no yog ib qho ntawm cov laj thawj vim li cas kuv tsis siv lub tshuab hloov pauv kom cais tawm cov khoom siv hluav taws xob, tsuas yog kom tsis txhob poob ntawm ob peb feem kaum ntawm ib lub watt thiab nce qhov ua tau zoo los ntawm ob peb lub ntsiab lus.

Hais txog qhov tsos

Tam sim no LED fluorescent teeb lub hwj chim mov, teeb manufacturers feem ntau xav kom nws muab tso rau hauv lub raj, xws li nyob rau hauv lub T8 raj. Ib feem me me yog sab nraud. Kuv tsis' tsis paub vim li cas nws thiaj li zoo li no. Qhov tseeb, cov khoom siv hluav taws xob built-in yog qhov nyuaj rau kev ua, thiab kev ua haujlwm tsis zoo. Tab sis kuv tsis paub tias yog vim li cas coob tus neeg tseem nug nws. Tej zaum lawv tag nrho poob nrog cua. Nws yuav tsum tau hais tias cov khoom siv hluav taws xob sab nraud yog kev tshawb fawb thiab yooj yim dua. Tab sis kuv kuj yuav tsum ua raws li cua, kuv yuav ua txhua yam uas tus neeg siv khoom xav tau. Tab sis nws yog ib qho nyuaj heev los ua ib tug built-in fais fab mov. Vim hais tias cov duab ntawm cov khoom siv hluav taws xob sab nraud tsis tas yuav tsum muaj, nws tsis' tsis muaj teeb meem loj npaum li cas koj xav ua, thiab koj xav ua dab tsi. Tsuas muaj ob hom khoom siv hluav taws xob built-in. Ib qho yog siv ntau tshaj plaws, uas txhais tau hais tias nws tau muab tso rau hauv qab lub teeb pom kev zoo, thiab lub teeb lub teeb tau muab tso rau hauv qab lub hwj huam mov. Qhov no yuav tsum tau lub hwj huam mov kom nyias nyias, txwv tsis pub nws yuav tsis raug ntsia. Tsis tas li ntawd, cov khoom siv tsuas tuaj yeem raug tsoo, thiab cov xaim ntawm cov khoom siv hluav taws xob tsuas tuaj yeem ua kom ntev. Kuv xav tias qhov no tsis yog txoj hauv kev zoo. Tab sis txhua tus feem ntau nyiam ua li no. Kuv' yuav ua nws. Kuj tseem siv tsawg dua. Muab ob qhov kawg, uas yog, muab tso rau ntawm ob qho kawg ntawm lub raj. Qhov no yooj yim dua ua thiab tus nqi qis dua. Kuv tau ua nws ua ntej, qhov yooj yim no ob lub built-in duab.

Cov lus nug txog cov kev xav tau thiab cov qauv hluav taws xob ntawm hom kev siv fais fab no

Kuv lub tswv yim yog vim hais tias lub hwj huam mov yuav tsum tau ua nyob rau hauv lub teeb, thiab tshav kub yog qhov loj tshaj killer ntawm LED teeb lwj, lub tshav kub yuav tsum me me, uas yog, lub efficiency yuav tsum siab.
