Dab tsi yog Lub Teeb Emitting Diode (LED):
LED sawv rau Lub Teeb Emitting Diode. Lub diode yog ib qho khoom siv hluav taws xob lossis cov khoom siv nrog ob lub electrodes (ib qho anode thiab cathode) los ntawm cov hluav taws xob ntws - tus yam ntxwv hauv ib qho kev taw qhia (hauv los ntawm anode thiab tawm los ntawm cathode). Diodes feem ntau yog tsim los ntawm cov khoom siv semiconductive xws li silicon lossis selenium - cov khoom hauv lub xeev uas ua hluav taws xob hauv qee qhov xwm txheej thiab tsis nyob hauv lwm tus (xws li ntawm qee qhov voltages, qib tam sim no, lossis lub teeb siv). Thaum tam sim no dhau los ntawm cov khoom siv semiconductor, lub cuab yeej emits pom lub teeb. Nws yog qhov sib txawv ntawm lub cell photovoltaic (ib qho khoom siv uas hloov lub teeb pom kev mus rau hauv hluav taws xob tam sim no).
Yog tias koj txaus siab rau cov lus qhia txog kev ua haujlwm ntawm LED li cas koj tuaj yeem nyeem ntxiv txog nws. Rau keeb kwm ntawm LED teeb pom kev nyeemntawm no.
Dab tsi yog Qhov Loj Upside rau LED Teeb
Muaj plaub qhov zoo rau LED teeb pom kev zoo:
LEDs muaj lub neej ntev heev rau txhua lwm yam teeb pom kev zoo (xws li LPS thiab fluorescent teeb tab sis tshwj xeeb tshaj yog piv rau hlau halide teeb). Cov LEDs tshiab tuaj yeem kav 50,000 txog 100,000 teev lossis ntau dua. Lub neej ntev li qub rau lub teeb hlau halide, los ntawm kev sib piv, yog 12-30% ntev npaum li qhov zoo tshaj plaws (feem ntau ntawm 6,000 thiab 15,000 teev).
LEDs yog lub zog tsis tshua muaj zog txheeb ze rau txhua lwm yam khoom siv teeb pom kev zoo. Muaj ntau qhov laj thawj rau qhov no suav nrog qhov tseeb tias lawv nkim lub zog me me hauv daim ntawv ntawm cov hluav taws xob infrared (kub), thiab lawv tawm lub teeb coj mus rau (tshaj li 180 degrees piv rau 360 degrees uas txhais tau hais tias muaj kev poob qis dua los ntawm qhov xav tau hloov pauv lossis reflect light).
Lub teeb zoo heev.
Tus nqi kho mob tsawg heev thiab hassle.
Dab tsi yog Me Me Upside rau LED Teeb:
Ntxiv nrog rau qhov zoo tshaj plaws, LED teeb kuj tseem muaj ntau yam me me perks. Cov no suav nrog cov hauv qab no:
Accessories: LEDs xav tau tsawg dua cov khoom siv teeb pom kev zoo.
Xim: LEDs tuaj yeem tsim los tsim kom muaj tag nrho cov spectrum ntawm pom lub teeb xim yam tsis tas yuav siv cov xim xim xim uas yuav tsum tau ua los ntawm cov teeb pom kev zoo.
Kev taw qhia: LEDs yog ib txwm muaj kev taw qhia (lawv tawm lub teeb rau 180 degrees los ntawm lub neej ntawd).
Loj: LEDs tuaj yeem me dua li lwm lub teeb (txawm tias incandescent).
Warm-Up: LEDs muaj kev hloov pauv sai dua (tsis muaj lub sijhawm sov sov lossis lub sijhawm txias).
Dab tsi yog qhov Downside rau LED Teeb?
Xav txog qhov upside koj yuav xav tias LED teeb yog qhov tsis muaj hlwb. Thaum qhov no tau dhau los ua rooj plaub, tseem muaj qee qhov kev lag luam uas yuav tsum tau ua thaum koj xaiv LED:
Tshwj xeeb, LED teeb kuj tseem kim. Tus nqi pem hauv ntej ntawm qhov project teeb pom kev zoo LED feem ntau ntau dua li feem ntau ntawm cov kev xaiv. Qhov no yog nyob deb ntawm qhov loj tshaj downside uas yuav tsum tau xav txog. Uas tau hais tias, tus nqi ntawm LEDs tau poob sai sai thiab raws li lawv txuas ntxiv tau txais yuav en masse tus nqi yuav poob mus ntxiv. Qhov ntawd txhua tus hais tias tus nqi pem hauv ntej ntawm LEDs thaum piv rau cov hlau halide teeb yog qhov tseeb nyob ze. Ob lub teeb (nyob ntawm tus qauv tshwj xeeb thiab cov lus qhia tshwj xeeb) feem ntau muag rau ib puag ncig $ 10- $ 30 rau ib lub luminaire. Tau kawg qhov no tuaj yeem hloov pauv hauv ob qho tib si nyob ntawm seb lub teeb tshwj xeeb hauv nqe lus nug.
Qhov twg yog LED nquag siv:
Thawj qhov kev siv ntawm LEDs yog nyob rau hauv Circuit Court boards rau computers. Txij thaum ntawd los lawv tau maj mam nthuav lawv daim ntawv thov kom suav nrog teeb pom kev, teeb pom kev zoo, thiab tsis ntev los no, teeb pom kev zoo sab hauv tsev thiab sab nraum zoov. LED teeb yog ib qho kev daws teeb meem zoo rau gymnasiums, warehouses, tsev kawm ntawv thiab cov tsev lag luam. Lawv kuj tseem yoog tau rau thaj chaw pej xeem loj (uas xav tau lub teeb muaj zog, muaj txiaj ntsig zoo tshaj qhov chaw loj), txoj kev teeb pom kev zoo (uas muaj cov xim zoo dua li cov teeb pom kev qis thiab siab siab sodium), thiab chaw nres tsheb.
Ntxiv Kev Sib Piv Zoo
Dab tsi yog qhov txawv ntawm Hlau Halide thiab LED Teeb:
Ob lub thev naus laus zis sib txawv yog qhov sib txawv ntawm kev tsim lub teeb. Hlau halide qij muaj cov hlau uas evaporated rau hauv inert gas nyob rau hauv lub iav casing thaum LEDs yog ib tug khoom lub xeev semiconductor technology. Ob lub thev naus laus zis tsim lub teeb zoo heev. LEDs zoo li yuav kav ntev dua thiab muaj zog ntau dua thiab tsis tshua muaj kev saib xyuas siv thev naus laus zis. Hlau halides muaj lub sijhawm sov so ntev thiab lub neej luv dua tab sis tsim lub teeb pom kev zoo thiab yog ib qho teeb pom kev zoo tshaj plaws thaum nws los txog rau cov xim txias txias.
Vim li cas LEDs yuav muab hlau halide qij tawm ntawm kev lag luam:
Qee lub teeb hlau halide muaj lub sijhawm sov so ntev (15-20 feeb) thaum lub teeb qhib thawj zaug lossis hauv qhov xwm txheej uas lub zog hluav taws xob cuam tshuam. Tsis tas li ntawd, muaj kev pheej hmoo me me uas lub teeb hlau halide tuaj yeem tawg. Txawm hais tias qhov no tsis tshua muaj thiab muaj kev tiv thaiv kev tiv thaiv uas txo kev pheej hmoo, tseem muaj feem cuam tshuam rau kev raug mob lossis kev puas tsuaj raws li qhov tshwm sim. Cov kev tiv thaiv ib txwm muaj xws li hloov qhov muag teev ua ntej lawv qhov kev xav tau kawg ntawm lub neej thiab en-masse raws li ib pab pawg (piv txwv li qhov chaw hloov qhov muag teev uas ua tsis tau). Qhov no tuaj yeem ua rau tus nqi nce ntxiv thiab txo qhov siv tau zoo ntawm lub teeb.
Tsis tas li ntawd, hlau halide qhov muag teev yog cov neeg siv hluav taws xob tsis zoo. Nyob rau sab saum toj ntawm no, lawv yuav tsum tau khiav mus rau lub sijhawm ntev dua li qhov xav tau tiag tiag vim qhov xav tau sov so. Qhov no tag nrho txhais ua tus nqi (feem ntau tshwm sim raws li daim nqi hluav taws xob ntau dua). Txawm hais tias lawv raug nqi ib yam li LEDs, hlau halide qhov muag teev yuav ntxiv cov nuj nqis nyob rau lub sijhawm raws li txoj kev tsis muaj txiaj ntsig uas lawv ua haujlwm thiab qhov zaus uas lawv yuav tsum tau hloov. Hauv ib lub tsev loj (xws li lub tsev khaws khoom, hockey rink, lossis chaw ntau pob), qhov kev ua tsis tau zoo no yuav ntxiv.
