1. LED Lub Teeb Lifespan:
Yooj yim tshaj plaws cov txiaj ntsig zoo tshaj plaws ntawm LED thaum piv rau cov kev daws teeb pom kev zoo ib txwm muaj lub neej ntev. Qhov nruab nrab LED siv 50,000 lub sijhawm ua haujlwm txog 100,000 cov sijhawm ua haujlwm lossis ntau dua. Ntawd yog 2-4 zaug kom ntev raws li feem ntau fluorescent, hlau halide, thiab txawm tias sodium vapor teeb. Nws yog ntau tshaj 40 zaug ntev npaum li qhov nruab nrab incandescent qhov muag teev.
Kev hloov pauv tsawg dua txhais tau ob yam loj: qis dua txij nkawm nyob rau hauv nqe lus ntawm lub zog thiab tus nqi qis rau cov khoom siv hloov chaw (vim hais tias cov qij tsuas tsis poob rau lub sijhawm ntev).
2. Kev txuag hluav taws xob LED:
Cov LED feem ntau siv hluav taws xob tsawg. Cov txheeb cais los saib rau thaum muab piv lub zog txuag ntawm cov teeb pom kev sib txawv sib txawv raug hu los ntawm ib ntawm ob nqe lus: kev ua kom zoo dua lossis siv lumens. Ob qho khoom siv no qhia qhov tseeb ntawm tus nqi ntawm lub teeb tawm hauv ib pawg ntawm cov fais fab (watts) siv los ntawm lub qhov muag teev. Hauv peb cov kev paub ntau ntawm cov teeb pom kev ua haujlwm LED rov qab ua haujlwm dhau los ntawm 60-75% kev txhim kho hauv lub zog tag nrho ntawm qhov chaw teeb pom kev zoo. Nyob ntawm cov teeb uas twb muaj lawm thiab tshwj xeeb qhov LEDs ntsia, qhov kev txuag nyiaj yuav ntau dua 90%. Koj tuaj yeem nyeem qee qhov kev tshawb fawb ntawm no.
Rau qee qhov sib piv ntawm LEDs thiab tas cov teeb pom kev zoo thev naus laus zis tawm muaj, nyeem cov kab hauv qab no:
LED vs CFL (Compact Fluorescent Teeb)
LED vs Fluorescent Teeb
LED vs HID (Kev Siv Khoom Ntau Lub Teeb Nruab Nruab; piv txwv li Hlau Halide)
LED vs HPS (Kev Kub Siab Sodium Teeb)
LED vs Incandescent Teeb
LED vs LPS (Tsis Tshua Muaj Kev Sodium Teeb)
3. Txhim Kho Txoj Kev Nyab Xeeb Nrog LEDs:
Kev nyab xeeb yog kab tias qhov feem ntau pom zoo dua thaum muaj qhov pom ntawm LED. Tus naj npawb ib qho kev phom sij thaum nws los rau teeb pom kev zoo yog kev tshaj tawm ntawm tshav kub. LEDs yuav luag yuav luag tsis muaj kev kub pem hauv ntej thaum lub teeb qoj ib txwm zoo li cov khoom siv sib hloov hloov ntau dua 90% ntawm tag nrho cov zog siv los ua lub zog rau lawv ncaj qha rau hauv tshav kub. Qhov ntawd txhais tau hais tias tsuas yog 10% ntawm lub zog siv hluav taws xob incandescent teeb yog qhov tseeb siv rau lub teeb (uas tseem ua rau lawv tsis tshua muaj txiaj ntsig piv rau LEDs). Tsis tas li ntawd, vim tias LEDs siv hluav taws xob tsawg dua lawv tuaj yeem ua haujlwm tau zoo ntawm cov hluav taws xob muaj hluav taws xob tsawg. Cov no feem ntau muaj kev nyab xeeb dua hauv qee qhov xwm txheej ua txhaum.
4. Cov Teeb LED Muaj Lub Cev Me:
Cov khoom siv tiag tiag LED yog qhov tsawg kawg nkaus. Cov cuab yeej hluav taws xob me me tuaj yeem tsawg dua li kaum tawm ntawm ib mm2 thaum cov cuab yeej hluav taws xob loj dua tseem muaj peev xwm tseem me me npaum li mm2. Lawv qhov loj me me ua rau LEDs hloov tau zoo heev rau cov naj npawb ntawm cov teeb pom kev zoo siv. Kev siv sib txawv rau LEDs suav nrog kev pom dav dav los ntawm lawv cov hauv paus hauv hluav taws xob Circuit Court teeb pom kev zoo thiab cov teeb liab sib txuas mus rau niaj hnub kev xav teeb pom kev zoo, thaj chaw nyob thiab kev lag luam daim ntawv thov, thiab txawm tias qhov chaw ntau pob teeb pom kev zoo. Koj tuaj yeem nyeem txog keeb kwm ntawm LED teeb pom ntawm no lossis keeb kwm ntawm lub teeb pom kev dav dav hauv no.
5. LEDs Muaj Qhov Zoo Ntau Qhov Ntsuas Ua Yeeb Yam (CRI):
CRI yog qhov ntsuas ntawm lub teeb ci lub peev xwm los qhia qhov tseeb xim ntawm cov khoom thaum piv rau qhov zoo tshaj plaws ntawm lub teeb (lub teeb pom kev zoo). High CRI feem ntau yog tus cwj pwm tsim nyog (txawm hais tias ntawm chav kawm, nws nyob ntawm daim ntawv thov yuav tsum muaj). LED feem ntau muaj qhov ntsuas siab heev (zoo) thaum nws hais txog CRI.
Tej zaum qhov zoo tshaj plaws txoj kev txaus siab rau CRI yog saib qhov sib piv ncaj qha ntawm LED teeb pom kev zoo (nrog CRI siab) thiab cov teeb pom kev zoo li teeb pom kev zoo li sodium vapor teeb (uas feem ntau tsis zoo CRI kev ntsuas thiab muaj qee kis yuav luag monochromatic). Saib cov duab hauv qab no los sib piv thiab sib piv ntawm ob qhov piv txwv:
Qhov ntau ntawm cov peev xwm ua tau rau sib txawv LED teeb yog feem ntau ntawm 65 txog 95 uas tau pom tias zoo tshaj. Koj tuaj yeem nyeem ntxiv txog CRI ntawm no.
6. LEDs Tsim Cov Cim Directional emissions:
Cov thev naus laus zis LED ua lub teeb ci rau 180 degrees xwb. Txhua lwm hom ntawm lub teeb tawm ntawm lub teeb 360 degrees ib ncig ntawm lub hauv paus. 360 degree emissions yuav tsum muaj cov khoom siv ntxiv kom muaj kev cuam tshuam thiab / lossis rov ua lub teeb. Qhov no ua rau cov nqi nce rau cov kab ke thiab feem ntau ua rau cov ntsiab lus poob tias qhov cuab yeej tsim nyog tsawg dua nws txwv tsis pub. Xav txog ib lub teeb uas taws tawm mus rau lub qab nthab - uas yog koj lub teeb txheem. Qhov teeb meem yog tias koj tab tom sim ua teeb pom kev hauv chav, tsis yog lub qab nthab. LEDs daws qhov teeb meem no kom meej thiab muab cov kev txuag nyiaj rov qab rau hauv cov lus ntawm lub zog tag nrho ntawm kev siv hluav taws xob.
7. LEDs Muaj Lub Tshaj Lij Zoo Nkauj Muaj Feem:
Vim tias LEDs tsawg heev lawv tuaj yeem siv nyob rau hauv txhua daim ntawv thov uas koj tuaj yeem xav. Lawv tuaj yeem muab sib xyaw ua ke rau hauv cov pob rau cov roj ib txwm, siv nyob rau hauv kev sib cais los ua lub teeb me me ntawm lub teeb, lossis strung tawm hauv kab xwm hauv ib txoj kab xwm. Tsuas yog hais txog txhua yam koj tuaj yeem xav txog tuaj yeem ua nrog LEDs.
8. Cov LED Yog Cov Khoom Uas Lub Zog Ntawm Lub Teeb (SSLs):
Cov LED muaj lub teeb lub xeev zoo. Qhov no txhais tau hais tias lub khob tsoos ib puag ncig lub teeb ci yog qhov tsis tsim nyog.
9. LED Dimming Peev Xwm:
Cov LED muaj peev xwm khiav lag luam ntawm txhua feem pua ntawm lawv lub zog ntsuas (0 txog 100%). Ntawm cov ntawv ceeb toom, lawv yuav tsum tau kho vajtse tshwj xeeb rau LED thev naus laus zis thiaj li yuav dim (txhais tau tias koj tsis tuaj yeem siv cov khoom siv sib luag rau lub qhov muag tsis pom lossis lwm yam kev siv tshuab teeb pom kev zoo). Qhov zoo ntawm kev khiav hauj lwm LED tsawg dua lub zog tag nrho yog tias lawv tau txais ntau dua li lub zog hluav taws xob tsawg. Qhov no kuj nce tag nrho tag nrho lub neej ntawm lub teeb nws tus kheej. Ob qho ntawm cov kev zoo no tsis tuaj nrog cov thev naus laus zis zoo li cov hlau txuas uas ua rau tau txais hluav taws xob tsawg dua ntawm lub zog qis thiab feem ntau tsis tuaj yeem tsaus ntuj.
10. LEDs Muab Instantaneous Tig Rau & Tsis Muaj Teeb Meem Nrog Rau Kev Hloov Mus Lawm:
LEDs tig thiab tua tam sim ntawd. Tsis muaj lub sijhawm ua kom sov zoo li nyob rau hauv rooj plaub ntawm hlau halide teeb. Txuas ntxiv, hloov ntau zaus tsis ua rau muaj kev cuam tshuam hauv lub cuab yeej.
11. Cov Teeb LED Muaj Kev Nyab Xeeb Ib Puag Ncig:
LED tsis muaj cov teeb meem ib puag ncig ib puag ncig teeb pom kev zoo li cov teeb pom kev zoo xws li fluorescent lossis mercury vapor teeb. Ob qho ntawm cov kev daws teeb meem no muaj cov tshuaj lom mercury nrog rau lub qhov muag thiab yog li xav tau kev tuav tshwj xeeb thaum kawg ntawm cov khoom lag luam muaj kev pab cuam lub neej. Tsis muaj ib qho kev txiav txim siab no tsim nyog nrog LEDs.
12. Cov Khoom Hluav Taws Xob Tau Ua Rau Tsim Txheem Ze Xoom UV Emissions:
Cov LED tso tawm ntau lub zog ntawm lawv lub zog hauv qhov pom kev pom, ib qho me me hauv qhov infrared spectrum, thiab tsis muaj ib qho twg hauv ultraviolet feem ntawm lub spectrum. Qhov no txhais tau tias LEDs muaj peev xwm nyab xeeb thiab ntseeg tau teeb pom kev zoo UV ntau yam zoo li kos duab uas yuav tawg thiab thuam lub sijhawm dhau los yog raug rau hom emission no.
13. LEDs Ua Rau Ntawm Cov Hluav Taws Xob Tsawg:
Feem ntau LED ua haujlwm ntawm qhov hluav taws xob tsawg heev. Qhov no ua rau lawv tsim nyog siv rau hauv cov ntawv thov teeb pom kev zoo sab nraum zoov uas lwm cov teeb pom kev zoo yuav tsis ua raws li cov cai xws li nrog cov tsev dej hiav txwv uas cov av theem ntawm qhov chaw nyob hauv cov dej nyab.
14. LEDs Ua haujlwm tau zoo hauv qhov txias thiab kub:
LED ua haujlwm tau zoo nyob rau hauv ntau hom kev ua haujlwm tsis muaj qhov cuam tshuam loj.
15. Correlated Xim Kub (CCT):
Cov LED muaj nyob rau hauv qhov sib txawv ntawm qhov sib txheeb ntawm cov xim kub (CCT) qhov tseem ceeb. Lawv tuaj yeem tau yuav nrog "sov," daj li ci, zoo li "txias," lub teeb dawb thiab ntau txoj kev xaiv. Koj tuaj yeem nyeem ntxiv txog CCT ntawm no.
