Dallas cov tswv tsev yuav tsum siv cov teeb pom kev zoo LED
Cov kev txhim kho tshiab thiab ntxim nyiam tshaj plaws hauv kev teeb pom kev zoo yog kev siv LEDs (Lub Teeb Emitting Diodes). Lub teeb me me, cov teeb pom kev zoo hu ua LEDs yog qhov ruaj khov thiab siv zog. Piv nrog rau cov teeb pom kev zoo, LEDs coj txawv txawv. Vim li no, LEDs muaj zog dua thiab siv tau ntev dua li cov khoom siv hluav taws xob zoo li qub.
Qhov zoo ntawm LED teeb pom kev zoo.
Qhov zoo
Zog txuag hluav taws xob: LEDs tam sim no tuaj yeem tsim 135 lumens ib watt.
Extended Lifetime — yog tsim kom raug, 50, 000 teev lossis ntau dua
Muaj zog - Raws li LEDs yog tsim los ntawm cov khoom siv thiab tsis muaj filaments, raj, los yog qhov muag teev kom tawg, lawv kuj hu ua "Solid State Lighting (SSL)".
LEDs tsis xav tau lub sijhawm sov so thiab pib teeb pom kev hauv nanoseconds.
Tsis muaj kev cuam tshuam los ntawm qhov txias - LEDs "nyiam" qhov kub thiab txias thiab yuav tig rau txawm tias nyob rau hauv qis qis qis.
LEDs yog kev taw qhia, yog li tsis muaj lub teeb khib nyiab vim koj tuaj yeem taw qhia lub teeb rau hauv kev coj koj xav tau.
Superb Colour Rendering - Tsis zoo li lwm qhov chaw teeb pom kev zoo li fluorescents, LEDs tsis ua kom muaj xim, ua rau lawv zoo tagnrho rau kev nthuav qhia thiab khw muag khoom.
Ib puag ncig tus phooj ywg - LEDs tsis muaj mercury lossis lwm yam khoom uas tsim kev puas tsuaj.
Controllable - LEDs muab qhov ci ci thiab xim xim.
Qhov tsis zoo
Kev phom sij xiav: Raws li cov qauv kev nyab xeeb ntawm qhov muag xws li Kev Pom Zoo rau Kev Nyab Xeeb Kev Nyab Xeeb rau Kev Nyab Xeeb Kev Nyab Xeeb rau Lub Teeb thiab Teeb Teeb, cov LEDs xiav thiab cov xim dawb-dawb tam sim no tuaj yeem tawm teeb xiav ntau dua li muaj kev nyab xeeb rau tib neeg lub qhov muag.
Lub teeb zoo: Piv nrog rau lub cev dub radiator, xws li lub hnub lossis lub teeb incandescent, feem ntau ntawm cov xim dawb-dawb LEDs muaj spectra uas txawv heev. Vim yog metamerism, cov xim liab tau tsim dua tshiab tshwj xeeb tshaj yog tsis zoo los ntawm cov qauv phosphor-raws li txias-dawb LEDs, ua rau cov xim ntawm cov khoom raug pom txawv nyob rau hauv qhov txias-dawb LED teeb pom kev zoo dua nyob rau hauv tshav ntuj lossis incandescent qhov chaw. Txawm li cas los xij, piv rau cov LEDs dawb niaj hnub no, cov xim muaj peev xwm ua tau zoo ntawm cov teeb pom kev zoo fluorescent feem ntau yog subpar.
Kub dependence: Qhov chaw ua haujlwm qhov kub thiab txias muaj qhov cuam tshuam loj rau kev ua haujlwm ntawm LED. Kev kub siab ambient tej zaum yuav ua rau lub pob LED overheat yog hais tias lub LED yog tsav nyuaj heev, uas tej zaum yuav ua rau lub gadget malfunction. Txhawm rau txhawb nqa lub neej ntev, xav tau kom muaj cua sov txaus. Qhov no yog qhov tseem ceeb thaum xav txog kev siv tsheb, kev kho mob, thiab kev siv tub rog vim tias lub cuab yeej yuav tsum ua haujlwm thoob plaws qhov kub thiab txias thiab muaj qhov tsis ua haujlwm tsawg.
Blue pollution: Vim lub zog wavelength dependence ntawm Rayleigh tawg thiab qhov tseeb tias txias-dawb LEDs (piv txwv li, LEDs nrog kub xim kub) emit proportionally ntau xiav lub teeb dua lwm yam sab nraum zoov teeb qhov chaw xws li high-siab sodium teeb, txias-dawb. LEDs muaj peev xwm tsim tau ntau lub teeb muaj kuab paug. Kev siv cov teeb pom kev dawb nrog cov xim sib xws ntau dua 3, 000 K tau poob siab los ntawm International Dark-Sky Association.
Voltage rhiab heev: LEDs xav tau ib qho khoom siv hluav taws xob uas siab tshaj qhov pib thiab qhov tam sim no qis dua qhov ntsuas. Series resistors los yog tam sim no-tswj hwj chim qhov chaw yuav siv tau nyob rau hauv no.
Tus nqi pib siab: Piv rau feem ntau ntawm cov teeb pom kev zoo ib txwm muaj, LEDs tam sim no raug nqi ntau dua ib lumen. Qhov sib piv qis lumen tso zis, tsim nyog tsav tsheb hluav taws xob, thiab cov khoom siv hluav taws xob tag nrho ua rau tus nqi ntxiv.
Thaj chaw teeb pom kev zoo: Lambertian kis ntau dua li "qhov chaw" ntawm lub teeb yog qhov LEDs zoo li. Hauv cov ntawv thov uas xav tau rau lub teeb pom kev zoo, LEDs yog li nyuaj rau kev ua haujlwm. Divergence hauv qab ob peb degrees tsis tuaj yeem tsim siv LEDs. Tsis zoo li qhov no, lasers yuav tsim kab teeb nrog qhov sib txawv ntawm 0.2 degrees lossis tsawg dua.
