Koj puas paub cov lus nug feem ntau nug los ntawm cov neeg yuav khoom LED? Nws ib txwm yog lo lus nug no tias LED teeb yuav kav ntev npaum li cas? Los yog lawv lub neej expectancy yog dab tsi? Ntau zaus qhov chaw tau tso rau hauv qhov tsaus ntuj vim tias lub teeb LED tau hlawv tawm. Cov koob npe nrov thiab cov neeg siv khoom loj loj ntawm LED teeb tau qhia ntau txog qhov zoo ntawm LEDs. Cov teeb no tsis yog tsuas yog siv hluav taws xob ntau dua thiab txuag nqi, tab sis lawv paub txog kev ua neej nyob ntev heev.
Yog li niaj hnub no, cia peb tshem tawm qhov tsis meej pem no thiab paub vim li cas LED teeb pom kev zoo nyob ntev dua li lwm cov teeb pom kev zoo. Tab sis ua ntej ntawd, cia peb piv cov LED teeb nrog lwm hom teeb.
LED VS INCANDESCENT
Cov qhov muag tsis pom kev yog thawj qhov teeb pom kev zoo uas tau tsim los ntawm Thomas Edison hauv xyoo 1879. Cov qij no tau dhau los ua neeg nyiam heev tab sis muaj ntau qhov tsis zoo hauv lawv. Lawv xav tau lub zog ntau, lawv tso tawm sai dua li lwm lub teeb, thiab lawv tawm ntau heev. Txawm hais tias cov qij no tau hloov mus rau theem hauv ntau xyoo dhau los, lawv tseem yog cov qij tsis muaj txiaj ntsig tshaj plaws uas peb muaj.
Kev siv hluav taws xob los ntawm cov qhov muag teeb yog 5 npaug ntau dua li cov qij LED. Txhawm rau nthuav dav, yog tias peb muab ob lub qhov muag teev nrog tib lub zog, LED teeb yuav ci 5 npaug dua li lub teeb incandescent.
Muaj ib qho kev xav tsis zoo txog cov teeb pom kev zoo uas lawv pheej yig dua li LED teeb. Thiab yog tias peb piv cov nqi pem hauv ntej ntawm LED teeb, lawv yuav zoo li kim dua, tab sis lawv pheej yig dua li qhov muag teev hauv lub sijhawm ntev. Ntawm qhov tod tes, cov nqi them ua ntej ntawm cov qhov muag teeb yog pheej yig dua, tab sis lawv xav tau kev hloov pauv ntau zaus, uas ua rau lawv kim dua nyob rau lub sijhawm ntev.
LED VS HALOGEN
Tom ntej no duplication ntawm lub teeb incandescent yog lub teeb halogen. Lub teeb halogen tseem muaj cov yam ntxwv zoo ib yam li qhov muag teeb, tab sis muaj qee qhov teeb pom kev zoo uas ua rau lawv ua ntej ntawm qhov muag teev. Qhov sib txawv loj yog cov khoom siv los tsim Halogen Bulbs. Lub halogen tau ntim rau hauv lub qhov muag teev halogen, thiab yog li lub iav yog ua los ntawm cov iav ntshiab heev, piv txwv li, quartz. Qhov no yog ib qho ntawm cov laj thawj vim li cas qhov muag teev halogen yog kim dua li qhov muag teev.
Vim muaj cov roj halogen, tungsten filament kav ntev dua. Qhov no yog hu ua lub voj voog halogen. Lub voj voog halogen no ua rau lub teeb siv sijhawm ntev tshaj li qhov muag teev. Thaum peb tab tom tham txog halogen qhov muag teev thiab qhov muag teev, LEDs tseem yog tus yeej ntawm txhua tus hauv kev ua haujlwm, kev ua haujlwm ntev, lossis nta. Halogen qij tseem poob qis thaum piv rau LED teeb uas muaj 50, 000 teev ua haujlwm.
LED VS fluorescent
Fluorescent qhov muag teev ua haujlwm sib txawv dua li halogen thiab incandescent teeb. Cov teeb no tsis xav tau cov roj halogen es; lawv siv ib lub raj ntawm inert gas. Muaj ob qhov kawg ntawm lub raj: zoo thiab tsis zoo. Rau qhov zoo ntawm cov electrons, alternating tam sim no (AC) yog siv tsis yog tam sim no ncaj qha (DC).
CFLs yog cov teeb pom kev zoo tshaj plaws kom txog thaum LED tuaj rau hauv khw. Thaum piv rau LED teeb, CFL tawm ntau qhov khoob hauv kev lag luam teeb pom kev zoo. LEDs ib txwm coj tus thawj coj thaum nws los txog rau lub neej ntev thiab lawv qhov loj me. LEDs ua haujlwm zoo tshaj plaws thaum lawv khaws cia hauv qhov chaw kaw. Nyob rau hauv ib qho chaw kaw, LEDs yuav ua haujlwm li ob zaug li CFLs.
Vim li cas LEDs muaj lub neej ntev dua?
Muaj qee qhov zoo ntawm LED teeb uas ua rau lawv ua haujlwm tau zoo thiab ua rau lawv lub neej expectancy.
Tsawg Kub Dissipation
Tsawg Kub Dissipation
Qhov zoo ntawm cov LEDs yog tias lawv tawm cua sov me ntsis. Thaum tshav kub kub tuaj yeem ua yeeb ncuab ntawm kev ua neej ntev ntawm txhua yam khoom siv hluav taws xob. Raws li LEDs tawm cua sov tsawg, lawv muaj lub neej ntev dua. Ntxiv mus, LEDs yog compact heev, thiab qhov siab tshaj plaws ntawm lub teeb tuaj yeem siv los ua lub dab dej kub. Lub dab dej kub no yuav rub tawm cov cua sov rau ib puag ncig, kom ntseeg tau tias qhov muag teev cov khoom tsis kub hnyiab thaum ntxov.
Tsawg zog siv thiab compact loj
LEDs tau paub tias yuav tsum siv hluav taws xob tsawg dua vim tias cov khoom siv sab hauv ntawm lub teeb tsis tau tawg ua ntej lub sijhawm. Kev siv hluav taws xob tsawg tau ua rau LED teeb pom kev zoo heev ntawm cov neeg siv khoom. Kev siv hluav taws xob tsawg thaum kawg ua rau nws raug nqi ntau dua. Nrog rau cov yam ntxwv no, LED teeb tau dhau los ua cov teeb pom kev zoo tshaj plaws.
Solid-State Teeb pom kev zoo
Qhov laj thawj tseem ceeb rau kev siv lub neej ntev ntawm LED teeb yog tias lawv tau tsim nrog Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob. Lub Cheebtsam ntawm LED teeb yog ua los ntawm solid-state. Lawv tsis tas yuav muaj cov pa roj thiab lub sijhawm sov so ua haujlwm. Tsis zoo li Halogen teeb lossis fluorescent teeb, uas xav tau cov pa roj nruab nrab kom ua haujlwm, lawv tsuas yog xav tau cov khoom siv hluav taws xob kom ua haujlwm tau zoo. Thiab qhov no ua rau LEDs ruaj khov dua li lwm lub teeb.
