Koj puas paub tias cov lus nug feem ntau los ntawm cov neeg yuav khoom LED yog dab tsi? Tib lo lus nug yog nquag nug: Lub teeb LED ntev npaum li cas? Los yog lawv yuav nyob nruab nrab ntev npaum li cas? Vim tias lub teeb LED nquag kub hnyiab tawm, thaj chaw feem ntau nyob hauv qhov tsaus ntuj. Kev muaj koob meej thiab loj ntawm cov neeg siv khoom siv ntawm LED teeb tau ua rau muaj kev tshwm sim tseem ceeb txog cov yam ntxwv ntawm LEDs. Cov teeb no tau sau tseg tias muaj lub neej ntev heev ntxiv rau kev siv nyiaj ntau dua- thiab siv zog.
Cia peb tshem tawm qhov kev nkag siab tsis zoo tam sim no thiab tshawb pom tias vim li cas LED teeb pom kev zoo tshaj lwm yam teeb pom kev zoo ntawm lub neej ntev. Cia thawj qhov sib piv LED teeb nrog lwm hom teeb, txawm li cas los xij.
INCANDESCENCE VS. LED
Thomas Edison tau tsim thawj lub teeb pom kev zoo uas tau siv dav heev thaum nws tsim cov teeb pom kev zoo hauv xyoo 1879. Txawm hais tias cov qij no tau nrov heev, lawv muaj ntau qhov tsis txaus. Lawv haus ntau lub zog, hlawv tawm sai dua li lwm lub teeb, thiab tsim kom muaj cua sov ntau. Txawm hais tias maj mam hloov cov qij no tau dhau los xyoo dhau los, lawv tseem yog qhov tsawg tshaj plaws uas peb muaj.
Cov qij taws teeb siv tsib zaug ntau npaum li lub teeb ci LED. Los piav qhia, LED teeb yuav ci tsib zaug ci dua li lub teeb incandescent yog tias peb muab lawv ob qho tib si lub zog.
Muaj kev xav tsis thoob tias cov teeb ci incandescent tsis tshua kim dua li LED teeb. Tsis tas li ntawd, thaum lub teeb LED yuav tshwm sim kim dua pem hauv ntej, lawv qhov kawg tsis tshua kim dua qhov muag teeb. Incandescent qhov muag teev, ntawm qhov tod tes, muaj tus nqi qis dua tab sis yuav tsum tau hloov ntau zaus, ua rau lawv kim dua lub sijhawm.
Halogen vs LED
Lub teeb halogen yog qhov imitation tom ntej ntawm lub teeb incandescent. Halogen teeb tseem qhia ntau tus cwj pwm nrog cov teeb pom kev zoo, txawm li cas los xij qee lub teeb halogen tseem ua tau zoo dua qhov muag teeb. Cov khoom siv los tsim Halogen Bulbs yog qhov sib txawv loj. Vim hais tias cov halogen nyob rau hauv halogen qhov muag teev tau sau, quartz, ib hom iav ntshiab heev, yog siv los ua iav. Halogen qhov muag teev yog kim dua li cov teeb pom kev zoo rau ntau qhov laj thawj, suav nrog qhov no.
Lub tungsten filament kav ntev dua vim tias muaj roj halogen. Lub voj voog halogen yog qhov hu ua qhov no. Lub teeb kav ntev dua qhov muag teev ua tsaug rau lub voj voog halogen. Thaum nws los txog rau kev ua tau zoo, kev ua siab ntev, lossis cov yam ntxwv, LEDs txuas ntxiv ua haujlwm zoo dua ob qho tib si halogen thiab incandescent teeb. Thaum piv rau LED teeb, uas muaj 50, 000 teev ua haujlwm, cov qij halogen tseem poob qis.
Fluorescent vs LED
Halogen thiab incandescent teeb ua haujlwm sib txawv ntawm cov qij fluorescent. Es tsis txhob siv cov roj halogen, cov teeb no siv lub raj roj inert. Cov raj muaj qhov zoo kawg thiab qhov tsis zoo kawg. Alternating tam sim no (AC) yog siv los ntawm direct tam sim no (DC) kom ntseeg tau tias tsim nyog electron txaus.
Ua ntej LEDs nkag mus rau hauv kev ua lag luam, CFLs yog lub teeb hluav taws xob zoo tshaj plaws. CFL teeb pom kev zoo muaj ntau yam tsis zoo li piv rau LED teeb pom kev zoo. Thaum nws los txog rau durability thiab compactness, LEDs yeej ib txwm nyob rau hauv cov hlau lead. Lub kaw lus kaw yog qhov twg LEDs ua haujlwm ntawm lawv qhov ua tau zoo tshaj plaws. LEDs yuav kav ntev li ob zaug ntev npaum li CFLs nyob rau hauv ib qho chaw kaw.
