Koj puas to taub qhov teeb pom kev zoo ntawm LED? Xaiv qhov zoo LED, txuag nyiaj, thiab tiv thaiv koj ob lub qhov muag
1. Xim kub: Koj puas xav kom "tsim" lossis "so"? - Tsis txhob dag los ntawm tus lej
1.1 Qhov txawv ntawm 3000K thiab 6000K yog ntau tshaj li "daj" vs "dawb"
Tsis tshua muaj xim kub (2700-3000K) muab lub teeb sov so uas txhawb nqa melatonin secretion - zoo tagnrho rau chav pw, chav noj mov, thiab tsev kho mob pawg ntseeg. Cov xim kub kub (5000-6500K) txias thiab pab koj ceev faj - zoo meej rau cov chaw ua haujlwm, chav ua noj, thiab chav ua haujlwm.Kev sib xyaw ua ke ua rau pom kev chaosthiab tuaj yeem ua rau qhov tsis tau piav qhia.
1.2 Lo rau ib qho xim kub kub hauv tib qhov chaw
Tshwj tsis yog tias koj muaj qhov ntse tunable-dawb system, sib xyaw 3000K downlights nrog 6000K LED strips hauv chav nyob yuav zoo li "ob lub ntsej muag". Txoj cai zoo: khaws cov xim kub sib txawv hauv 1000K thoob plaws hauv chav tsev.
Ib kab lus: Chav pw → 2700-3000K, chav nyob → 4000K, chav ua noj / kev kawm → 5000-6000K.
2. Xim Rendering Index (CRI): Koj Lub Qhov Muag Qhia Ra80 los ntawm Ra95 hauv Ib Thib Ob
2.1 Tsawg Ra ua rau liab saib grey thiab tawv nqaij zoo li daj ntseg
Raws li tus qauv LED (Ra80), lub kua liab zoo li yas, thiab lub ntsej muag zoo li nkees thiab npub. High-CRI (Ra Ntau dua lossis sib npaug rau 90) lossis txawm tias tag nrho-spectrum (Ra Ntau dua lossis sib npaug rau 97) rov qab cov xim tseeb - tshwj xeeb tshaj yog rau cov tsev khaws puav pheej, khw muag khaub ncaws, thiab tsev kho mob.
2.2 Tsis txhob saib tsuas yog Ra – kos R9 (saturated liab) ib yam nkaus
Ntau lub teeb thov Ra90 tab sis muaj R9 tsuas yog 20. Cov xim liab tsis zoo ua rau tag nrho cov kev paub dhau los.Ib qho zoo tagnrho-spectrum LED xav tau R9 Ntau dua lossis sib npaug rau 90.
Kev sib piv ntawm lub ntiaj teb tiag tiag rau qib CRI sib txawv
| CRI qib | Hom Ra | R9 nqi | Liab tsos | Cov tawv nqaij tone tsos | Zoo tshaj rau |
|---|---|---|---|---|---|
| Standard LED | 80‑85 | 5‑20 | Daj, txiv kab ntxwv | Dawb / dawb | Chaw nres tsheb, txoj kev hauv tsev |
| High-CRI LED | 90‑93 | 50‑70 | Txaus luag tiag tiag | Ntuj | Chaw ua haujlwm, tsev kawm ntawv |
| Full-spectrum LED | 95‑98 | Ntau dua lossis sib npaug li 90 | Bright & tseeb | Rosy & noj qab nyob zoo | Tsev kho mob, tsev cia puav pheej, tsev high-end |
| Hnub ci | 100 | 100 | Zoo meej | Zoo meej |
Hauv qab kab: Rau kev siv hauv tsev, xaiv Ra Ntau dua lossis sib npaug rau 90. Rau cov ntawv siv xim tseem ceeb, mus ncaj nraim mus rau tag nrho cov spectrum (Ra Ntau dua lossis sib npaug rau 97 + R9 Ntau dua lossis sib npaug rau 90).
3. Kev ua tau zoo & Lub neej ntev: Kev txuag hluav taws xob thiab kev ua haujlwm ntev tuaj yeem ua ke
3.1 Kev ua tau zoo dua txhais tau tias lub zog tsawg dua, tab sis tsis txhob caum tus lej siab tshaj qhov muag tsis pom
Mainstream LEDs xa 120-150 lm / W; Cov kev ua tau zoo tuaj yeem ncav cuag 180+ lm/W. Tab sis ultra-high efficiency feem ntau tuaj ntawm tus nqi ntawm CRI (Ra yuav poob qis dua 80).Kev xaiv sib npaug: 130-150 lm / W + Ra Ntau dua lossis sib npaug rau 90 rau kev siv hauv tsev.
3.2 Lub neej nyob ntawm cov cua kub dissipation thiab kev tsav tsheb zoo
LED nti nws tus kheej tuaj yeem kav ntev dua 50,000 teev, tab sis cov cua kub tsis zoo ua rau lub lumen poob qis thiab tsav tsheb tsis ua haujlwm. Thaum xaiv lub luminaire,kov lub dab dej kub- aluminium zoo dua li yas, thiab cov fins tob dua txhais tau tias txias dua.
Tswv yim tswv yim: Reputable hom feem ntau hais tias "L70 Ntau dua los yog sib npaug rau 50,000h" - lub ntsiab lus ci yuav tsis poob qis dua 70% ntawm nws cov nqi pib tom qab 50,000 teev ntawm kev siv.
4. Anti-Glare & Flicker: Cov Killers Invisible
4.1 Qhov qis dua UGR, qhov yooj yim rau koj ob lub qhov muag
UGR (Unified Glare Rating) ntsuas qhov tsis xis nyob ntawm lub ntsej muag. Rau cov chaw ua haujlwm, UGR Tsawg dua lossis sib npaug rau 19 yog qhov lees txais, tab sis cov tsev kho mob / chav kawm yuav tsum tsom rau Tsawg dua lossis sib npaug rau 16, thiab cov khoom lag luam saum toj kawg nkaus ua tiav tsawg dua lossis sib npaug li 10.Qhov kev sim yooj yim tshaj plaws: Yog tias koj saib ncaj qha ntawm lub teeb thiab xav squint lossis saib deb, UGR siab dhau lawm.
4.2 Flicker tuaj yeem ua rau mob taub hau thiab qhov muag
Taw tes koj lub koob yees duab lub xov tooj ntawm lub teeb LED. Yog tias koj pom dov kab txaij ntawm qhov screen, qhov flicker yog qhov hnyav. Cov tsav tsheb zoo LED siv "flicker-free constant-current" designs with a flicker depth of<1%.
Ib kab lus xaus: Nug ob lo lus nug thaum yuav lub teeb - "UGR yog dab tsi?" thiab "Koj puas muaj daim ntawv qhia flicker?" - thiab koj yuav lim tawm 80% ntawm cov khoom tsis zoo.
Koj puas xav tau qhov zoo-CRI, lub neej ntev, tsis muaj flicker-dawb LEDs rau koj qhov project?
