Vim li cas COB LED Downlights yog qhov nyiam tshiab hauv kev lag luam teeb pom kev zoo?
Cov chaw tos txais hauv tsev so, cov chav ua yeeb yam, cov tsev nyob qib siab - yog vim li cas cov chaw no thiaj li nyiam cov teeb ci COB? Cov lus teb yog nyob rau hauv lub teeb qhov chaw technology.
Thaum koj taug kev mus rau hauv lub tsev so tsib lub hnub qub chaw tos txais, cov neeg tsis paub qab hau, cov teeb pom kev zoo ntawm lub qab nthab yog feem ntau COB recessed downlights. Thaum koj sawv hauv qhov chaw kos duab qhuas txog cov roj pleev xim, lub teeb pom kev ncaj ncees nyob ntawm qhov chaw ntawm tus ncej tej zaum yog los ntawm COB downlight. Tsis zoo li cov teeb pom kev zoo ib txwm ua rau lub teeb ci hnyav, lossis lub teeb qab nthab zoo tib yam uas cuam tshuam lub teeb xoob, COB cov teeb pom kev zoo siv tib lub teeb ci "concentrated" kom xa qhov tseeb, kev nplij siab thiab kev xav zoo.
Los ntawm SMD mus rau COB: Ntau tshaj li Ib Lub Ntim Evolution
Ua ntej, cia peb teb cov lus nug yooj yim: COB yog dab tsi? COB sawv cev rau "Chip-on-Board" - ntau lub chips LED tau ntim ncaj qha mus rau hauv ib qho substrate, tsim ib qho, siab-density light source module. Nyob rau hauv sib piv, SMD (Nto-Mounted Device) siv ntau tus neeg chips mounted nyias nyob rau hauv ib tug Circuit Court board, txhua emitting lub teeb ntawm nws tus kheej.
Qhov sib txawv ntawm ob lub thev naus laus zis tau tshwm sim hauv peb qhov tseem ceeb: kev ua tau zoo ntawm lub teeb, lub teeb zoo thiab kev tswj xyuas thermal. Cov lus hauv qab no muab kev sib piv ncaj qha:
| Parameter | COB LED Downlight | SMD LED Downlight |
|---|---|---|
| Lub teeb qhov chaw daim ntawv | Ib qho kev sib xyaw ua ke, ze ntawm "luminous nto" | Ntau tus neeg chips, dispersed emission |
| Beam lub kaum sab xis | Nqaim mus rau nruab nrab (15℃-60 degree), ua kom pom tseeb | Lub kaum sab xis (90℃+), dav thiab sib xws |
| Luminous flux ceev | Txog li 300 lm / mm² | Feem ntau qis dua 100 lm / mm² |
| Xim Rendering Index | CRI Ntau dua lossis sib npaug rau 90 ua tiav, qee qhov Ntau dua lossis sib npaug rau 95 | Standard Ntau dua los yog sib npaug rau 80, high-end mus txog 90+ |
| Xim kub sib xws | CCT <50K | CCT feem ntau> 200K |
| Thermal tsis kam | 1.2-2.5℃/ W | 5-8℃/ W |
| Rated lifespan | >50,000 teev | ~ 30,000 teev |
Los ntawm lub rooj, nws yog tseeb hais tias COB qhov zoo nyob rau hauv "precision" - concentrated lub teeb ci, muaj tseeb xim rendering, thiab zoo heev thermal tswj. Cov yam ntxwv no ua rau nws nyiam kev daws teeb meem rau kev lag luam teeb pom kev zoo.
Peb Qhov Zoo Tshaj Plaws ntawm COB Downlights
1. Lub teeb zoo dua: ib lub teeb huv huv yog tsim nyog kaum lub teeb tawg
Vim hais tias SMD downlights siv cov chips dispersed, lawv emit lub teeb nyob rau hauv ib tug dav cheeb tsam, feem ntau tsim ntau ntxoov ntxoo thiab overlapping "dab" cuam tshuam. COB downlights, nrog rau lawv cov teeb pom kev zoo nyob rau hauv ib cheeb tsam me me, tsim ib lub teeb huv si, zoo ib yam nrog cov npoo ntshiab - tsis muaj ntau qhov ntxoov ntxoo, tsis muaj qhov sib txawv. Ntxiv mus, COB chips muaj qhov zoo dua qub hauv kev ua xim siab; premium COB downlights tuaj yeem ua tiav CRI Ntau dua lossis sib npaug rau 90 lossis txawm tias ntau dua lossis sib npaug rau 95, ua rau cov khoom pov thawj, cov khoom muag thiab cov tawv nqaij tones tshwm sim ntau dua thiab muaj tseeb.
2. Precise light control: aim qhov koj xav tau
Vim hais tias lub teeb COB los ntawm thaj chaw compact, zoo-txhais, thaum ua ke nrog optical reflectors thiab lo ntsiab muag, nws tso cai rau lub teeb pom kev zoo heev - los ntawm qhov chaw nruj 15℃mus rau 60℃dej nyab, uas yuav luag tsis muaj teeb pom kev zoo lossis tsis pom kev. Rau cov ntawv thov uas xav tau kev tswj hwm nruj - cov khoom lag luam siab kawg, teeb pom kev zoo hauv tsev, teeb pom kev zoo hauv tsev so - qhov no yog qhov nyuaj rau SMD cov kev daws teeb meem kom phim.
3. Cov cua kub zoo dua: me me, kev txawj ntse loj
COB chips ntim ntau LEDs ncaj qha mus rau ceramic lossis aluminium substrate, ua rau txoj kev luv luv thiab qis thermal kuj (COB: 1.2-2.5℃/ W vs SMD: 5-8℃/ W). Qhov no txhais tau hais tias COB downlights ua tau zoo dua kev sib txuas ntawm qhov kub thiab txias thaum lub sijhawm ua haujlwm ntev (COB tuaj yeem nyob qis dua 85 degree, thaum SMD ntawm tib lub zog feem ntau tshaj 110 degree), yog li txuas lub neej ntev thiab txo qis lumen depreciation. Nrog rau qhov zoo tshaj plaws tuag-cam khwb cia txhuas cua sov dab dej, COB downlights feem ntau kav ntev dua 50,000 xuab moos - kev saib xyuas qis dua li cov khoom siv niaj hnub.
Xaiv COB Downlights: Ua kom pom tseeb ntawm peb qhov tsis muaj
Muaj ntau ntau COB downlight qauv nyob rau hauv kev ua lag luam, tab sis qhov kev ua tau zoo tiag tiag sib txawv los mus rau peb yam nram qab no:
| Parameter | Pom zoo tus nqi | Yog vim li cas |
|---|---|---|
| Xim Rendering Index (CRI) | Ntau dua lossis sib npaug rau 90 (kev lag luam), Ntau dua lossis sib npaug rau 95 (high-end / kos duab zaub) | Kev tsim cov xim tiag tiag cuam tshuam rau kev nthuav qhia cov khoom muag thiab kev nplij siab pom |
| Correlated Xim Kub (CCT) | 2700K-3000K (sov ambience), 4000K (nruab nrab chaw ua haujlwm / lag luam), 5000K + (siab pom kev xav tau) | Cov scenes sib txawv yuav tsum muaj xim sib txawv; Lub teeb sov ua kom cua, lub teeb txias ua kom pom tseeb |
| Beam lub kaum sab xis | 15℃-30℃(accent / pom teeb pom kev zoo), 45℃-60℃(ua haujlwm / teeb pom kev zoo) | Beam lub kaum sab xis txiav txim siab kev pab them nqi thiab kev tsom xam, ncaj qha cuam tshuam rau spatial txheej |
Tsis tas li ntawd, niaj hnub COB downlights feem ntau muaj cov qauv tiv thaiv glare; ntau cov khoom lag luam zoo ua tiav UGR Tsawg dua lossis sib npaug rau 19, txo qhov pom kev qaug zog. Thaum xaiv, nws raug nquahu kom xav txog qhov chaw siv, qab nthab qhov siab thiab qhov chaw tso saib tseem ceeb. Kev cob qhia teeb pom kev zoo simulation software zoo li DIAlux tuaj yeem siv rau kev txheeb xyuas thaum xav tau.
Qhov twg yog COB Downlights Zoo Tshaj Plaws?
COB downlights tau dav siv, tshwj xeeb tshaj yog nyob rau hauv peb hom nram qab no:
- Kev lag luam wholesale & zaub- Cov khw muag khaub ncaws, khw muag khoom jewellery, tsheb exhibition, thiab lwm yam, xav tau lub teeb precisely coj mus rau cov khoom kom nthuav dav kev ntxhib los mos thiab cov ntsiab lus. COB downlights 'siab CRI thiab meej beam tswj ua cov khoom "naturally radiant".
- Tsev so & clubs- Lobbies, txoj kev hauv tsev, tsev noj mov, chav qhua - thaum so rau hauv qab nthab, COB downlights nrog lawv cov qauv tsim tsis muaj teeb meem thiab kev tswj cov kab ncaj nraim tsim kom muaj huab cua zoo yam tsis muaj kev cuam tshuam.
- High-end tsev nyob- Cov chav nyob uas tsis muaj lub teeb ci tseem ceeb, tsom teeb pom kev zoo tshaj hauv chav ua noj Islands tuaj, teeb pom kev zoo rau daim duab kos duab - COB downlights ua tau zoo heev. Cov khoom siv lawv tus kheej muaj qhov tsis pom kev pom, tab sis lub teeb lawv tsim muaj qhov cuam tshuam loj.
