Ua tawg, hlawv tshaj tawm qhov khoom ntawm yav dhau los, teeb liab-emitting diode ( LED ) teeb tuaj nyob rau hauv ib qho kev dazzling ntawm cov khoom thiab siv. Qhov zoo tshaj plaws uas kub-txias hluav taws xob muaj teeb ntawm pawg me me, ci diav, lawv tuaj yeem tsim kho kom haum txhua daim ntawv thov lossis kev siv tshuab. Rechargeable LED teeb yuav raug siv rau cov ntawv siv tau txav xws li photography, pom teeb pom kev zoo, thiab teeb pom kev nyab xeeb. Lawv cov qauv muaj zog thiab tsis muaj zog txaus yuav cia lawv ua haujlwm rau cov roj teeb uas muaj roj. Cov chav dej uas tau tawm ntawm lub tshuab hluav taws xob tuaj yeem tsim tawm ntawm cov hluav taws xob, xws li cov hluav taws xob hauv tsev thiab lub tsheb npav, siv cov chargers, adapters, los sis qee zaus tuav.
LED teeb ua haujlwm hauv tshuab hluav taws xob, los ntawm kev siv hluav taws xob ntau dhau ib cov khoom siv hluav taws xob hauv qhov Circuit Court. Cov roj electrons ua stimulated thaum lawv raug thiab tso tawm los ntawm cov ntaub ntawv no, tawm ua cov photons los yog teeb. Cov teeb cig no tau sau rau hauv ib lub txaj, feem ntau zoo li lub me me, yas teeb, tsim los ua kom pom tseeb thiab npaj lub zog ua lub teeb. Cov txheej txheem tso cai rau lub teeb rau ntawm ntau xim, nyob ntawm ntau yam ntaub ntawv thiab kev siv zog. Diodes, los yog hluav taws xob hluav taws xob nyob hauv cov ntsiab lus LED , yuav ntxiv zuj zus thaum muab tso ua ke rau ntau lub teeb thiab mob siab rau kev siv reflectors thiab cov ntxaij lim dej.
Noj qhov chaw ntawm cov pa hluav taws kub lub teeb, cov roj teeb uas muaj roj tau ua dua tuaj yeem ua kom sov dua thiab yuav tsum tau siv zog dua. Cov teeb cig hauj lwm yuav raug tshem tawm thiab zaum ntawm cov taw, nce, los yog hooks rau kev nkag yooj yim ntawm chaw nres tsheb los yog sab nraum zoov. Cov khoom lag luam muaj xws li cov tsom iav tsaus ntuj, kev teeb tsa kev ua si, teeb vaj teeb, thiab kev teeb.
Rechargeable LED teeb yuav raug tuav los yog siv nyob rau ntawm lub teeb chained light. Cov huab cua tsis muaj huab cua yuav ua rau cov khoom siv tes ua si rau kev kho khoom ua haujlwm; Cov teeb meem no ntev ntev, cov roj teeb uas muaj teeb meem tuaj yeem tuaj yeem ua haujlwm rau thaum muaj xwm txheej ceev xws li hluav taws xob tuag lossis tsheb kev puas tsuaj. Sab nraum zoov teeb nyob rau hauv cov chaw ruaj khov rau kev tsim kho kev lag luam muaj peev xwm ua rau kev ua kom hnov suab thiab ua kom sov hnub ci. Lawv cov kev siv hluav taws xob qis feem ntau tso cai rau tsev tsis muaj vaj tse uas tsis muaj ntawv tso cai hluav taws xob.
Lub neej ntawm cov roj teeb uas muaj teeb meem tau ua yog nyob ntawm seb lawv siv ntau npaum li cas, nrog rau cov roj teeb uas lawv xav tau. Cov roj ntsha Alkaline muaj ntau thiab tsawg dua, thiab yuav tsum tau hloov ntau dua rau cov kev yees tshiab. Cov hom kev kawm, xws li lithium-ion thiab cov roj hmab nikel-cadmium roj teeb, muaj kev siv zog ntau dua thiab kev phooj ywg zoo, feem ntau ntawm cov nqi ntau dua.
Muaj ntau hom roj teeb txawb tau ua haujlwm lwm qhov chaw. Roj teeb ci teeb taws rau cov chaw pw thiab ua rau tsis muaj hluav taws kub. Cov teeb meem thaum muaj xwm ceev zaum hauv cov qauv sawv cev tos kom tuaj yeem pib ua haujlwm hauv lub hwj chim; lawv muab teeb pom kev nyab xeeb thaum muaj teeb meem lossis hluav taws hauv cov tsev thiab cov lag luam. Cov tsho muaj peev xwm siv tau rau hauv thaj chaw tua tsiaj los yog cawm khiav haujlwm, thaum siv lub qab ntim qhov chaw dai sab nraud. Cov khoom ua tau zoo, cov khoom hluav taws xob, nrog lawv cov sij hawm ntev ntawm kev lag luam, qis zog noj, thiab tsawg heev ntawm hluav taws los yog tawg, sau ntau qhov chaw tiaj dub nrog lawv kos npe spectral ci.
