Dab tsi yog qhov txawv ntawm COB thiab SMD LED Sawb?

Thaum xaiv LED strips, ntau tus neeg siv khoom ntsib teeb meem uas tsis tuaj yeem zam: lawv yuav tsum xaiv COB lossis SMD? Txawm hais tias ob hom yuav zoo sib xws thiab muaj teeb pom kev zoo thaum nruab nrog lub diffuser, muaj qhov sib txawv tseem ceeb hauv kev siv tiag tiag -xws li lub teeb sib xws thiab lub neej ntev mus rau cov ntawv thov tsim nyog. Niaj hnub no, peb yuav rhuav tshem cov ntsiab lus ntawm ob hom los pab koj xaiv txoj cai.

SMD stands rau Surface Mounted Device. Cias muab, ib tug neeg LED chips yog soldered mus rau ib tug PCB (Printed Circuit Board) siv nto-mount technology, nrog rau tej qhov sib txawv ntawm cov chips. Cov qauv muaj xws li 2835, 3528, thiab 5050, qhov twg cov lej qhia qhov ntev ntawm LED chips.

Qhov zoo ntawm hom kab sawb no suav nrog cov thev naus laus zis paub tab, cov txheej txheem tsim khoom tsim qauv, thiab ntau tus nqi ntau yam - muab kev xaiv los ntawm kev nkag - cov khoom qib mus rau siab -CRI (Color Rendering Index) qauv. Qhov tsis zoo kuj tseem pom tseeb: vim tias cov chips yog qhov chaw teeb pom kev sib cais, cov ntsiab lus ntawm lub teeb pom tau meej meej thaum saib cov sawb ze ze -ib qho tshwm sim uas paub hauv kev lag luam li "dotting effect" lossis "graininess."

COB sawv cev rau Chip On Board. Nyob rau hauv cov txheej txheem no, LED chips yog bonded ncaj qha mus rau lub substrate; es tsis txhob siv ib tus zuj zus ntim cov hlaws LED, cov chips tau ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom. Qhov sib nrug ntawm cov chips yog nruj heev, feem ntau ntsuas hauv millimeters lossis tsawg dua.

Due to the high chip density, the light-emitting surface of a COB strip appears as a continuous line rather than a series of intermittent light points. Qhov no yog qhov laj thawj tseem ceeb rau nws qhov muaj koob meej loj hlob nyob rau hauv siab - xaus teeb pom kev zoo thiab kho kom zoo nkauj sab hauv xyoo tas los.

Qhov no yog qhov sib txawv tshaj plaws tam sim ntawd ntawm ob. Txawm hais tias thaum siv cov channel diffusing lossis frosted npog, cov ntsiab lus teeb pom kev ntawm tus kheej tseem pom ntawm SMD strips thaum saib ze -tshwj xeeb tshaj yog cov qauv qis- ntom ntom uas muaj qhov sib txawv ntawm cov chips. COB strips yog dawb kiag li ntawm qhov teeb meem no; lub teeb -emitting nto yog zoo ib yam thiab tas mus li, nrog zoo li tsis pom ib tug kab ntawm nti kev npaj, tsim ib tug pom kev tshwm sim uas zoo li ib tug khoom " sawb ntawm lub teeb" es tsis yog ib tug "txoj hlua ntawm LED hlaws." Yog tias tus neeg siv khoom qhov project xav tau siab - zoo, ua kom pom kev zoo- xws li rau cov teeb pom kev zoo hauv tsev, cov tsev so hauv tsev, lossis kev teeb tsa kos duab pom nyob ze - qhov zoo ntawm COB thev naus laus zis tau pom tseeb tshwj xeeb.

SMD LED strips muaj qhov hloov pauv tau yooj yim PCBs uas tso cai rau lub kaum sab xis dav dua thiab nruj dua khoov radii, ua rau lawv zoo tagnrho rau kev teeb tsa nyuaj -xws li cov uas yuav tsum tau ua raws li cov npoo nkhaus lossis kev taw qhia ntawm ntau lub ces kaum.

Due to the dense arrangement of chips and the typical application of a protective coating, COB strips are slightly less flexible than SMD strips and generally require a larger bend radius. Txawm li cas los xij, cov khoom lag luam hloov pauv COB tsis ntev los no tau nkag mus rau hauv kev lag luam nrog kev txhim kho khoov muaj peev xwm, txawm tias ntawm tus nqi siab dua.

Hais txog cov cua kub dissipation, qhov ntom nti layout ntawm COB strips concentrates tshav kub nyob rau hauv ib cheeb tsam, muab siab dua xav tau ntawm lub substrate thiab thermal tswj cov ntaub ntawv; siab-cov khoom zoo COB feem ntau siv txhuas-raws li substrates los yog ntxiv cov cua sov- cov qauv dissipating.

SMD strips muaj qhov dav dav ntawm LEDs, uas ua rau muaj kev sib txawv ntawm cov cua sov ntau dua thiab tsis tshua muaj siab thermal stress-txawm tias cov cua kub dissipation tseem yuav tsum tau txiav txim siab rau siab - cov qauv ntom ntom (xws li siab - ntom 5050 strips). Zuag qhia tag nrho, muab cov tsav tam sim no thiab thermal tswj tau zoo sib xws, ob qho tib si thev naus laus zis tuaj yeem ua tiav lub neej zoo; tsis tuaj yeem tsuas yog tshaj tawm tias muaj lub neej nyob ntev dua li lwm tus.

Ua tsaug rau lawv cov nqi -kev ua tau zoo thiab ntau yam ntawm cov qauv muaj, SMD LED strips yog siv dav hauv kev lag luam teeb pom kev zoo, teeb pom kev hauv tsev, kos npe, thiab theem teeb pom kev zoo-tshwj xeeb tshaj yog rau cov haujlwm uas muaj peev nyiaj tsawg lossis cov uas xav tau kev teeb tsa loj -.

COB LED strips zoo dua rau cov ntawv thov uas xav tau lub teeb pom kev zoo thiab qhov zoo sib xws ntawm qhov ze, xws li boutique qhov rais qhia, cov khoom pov thawj, tsev so sab hauv accents, thiab cov rooj tog teeb pom kev zoo (xws li, recessed wardrobe lossis phau ntawv teeb pom kev zoo). Cov neeg siv khoom hauv cov haujlwm no feem ntau txaus siab nqis peev me ntsis ntxiv rau cov teeb pom kev zoo ua kom zoo nkauj COB muab.

Tsis muaj qhov kev xaiv "zoo dua" ntawm COB thiab SMD; qhov kev xaiv kawg yog nyob ntawm cov kev cai tshwj xeeb ntawm qhov project. SMD LED strips yog ib qho kev xaiv txhim khu kev qha yog tias koj saib xyuas tus nqi tseem ceeb -kev ua tau zoo, xav tau kev siv ntau yam thoob plaws hauv daim ntawv thov, thiab ua haujlwm nrog cov peev nyiaj nruj heev. Txawm li cas los xij, yog tias koj qhov phiaj xwm xav tau kev sib txuas ntawm lub teeb txuas ntxiv thiab ua kom zoo nkauj zoo nkauj -thiab koj txaus siab los nqis peev rau qhov pom kev zoo dua-COB LED strips muab cov kev daws teeb meem zoo dua. Txhawm rau kom ntseeg tau tias qhov zoo tshaj plaws rau koj qhov project, nws yog ib qho tseem ceeb uas yuav tsum xav txog cov tswv yim tshwj xeeb xws li cov kaum sab xis, cov peev xwm ua kom sov, thiab Xim Rendering Index (CRI).

Yog tias koj xaiv LED strips rau ib qhov project thiab tsis paub meej tias COB lossis SMD yog qhov kev xaiv zoo dua, thov qhia cov ntsiab lus hais txog koj daim ntawv thov, ib puag ncig kev teeb tsa, thiab pob nyiaj siv. Peb tuaj yeem pom zoo cov qauv tsim nyog raws li koj qhov kev xav tau tshwj xeeb thiab muab cov qauv rau kev sim, tso cai rau koj los sib piv cov kev ua tau zoo ntawm ob hom.
