COB LED vs SMD LED: Qhov Ci Nkaus, Kev Ua Haujlwm Zoo & Tus Nqi Sib Piv Head-to-Head

Kev Taw Qhia

Teeb pom kev zoo pib ua ib yam cuab yeej yooj yim rau kev nyab xeeb thaum hmo ntuj. Niaj hnub no, nws lub hom phiaj tau nthuav dav heev. Tshaj li qhov pom kev xwb, teeb pom kev zoo tam sim no tswj hwm tus cwj pwm ntawm qhov chaw, tsav tsheb zoo nkauj, thiab ua kom pom tseeb cov xwm txheej.

Qhov kev hloov pauv no vam khom tag nrho rau cov thev naus laus zis niaj hnub no. Peb tau hloov pauv ntawm cov nplaim taws yooj yim mus rau cov khoom siv hluav taws xob siab heev (semiconductor-based Light Emitting Diodes, lossis LEDs). Cov teeb niaj hnub no muaj zog heev. Lawv siv ib feem me me ntawm lub zog ntawm cov teeb incandescent qub thiab kav ntev txog li 25 npaug.

Txawm hais tias lawv nyob txhua qhov chaw, tseem muaj kev tsis paub meej txog lo lus no. Ib qho kev nkag siab yuam kev feem ntau yog piv rau LED ib txwm muaj rau SMD zoo li lawv yog cov thev naus laus zis sib txawv kiag li. Rau qhov meej meej, ib lub cuab yeej uas tau teeb tsa ncaj qha rau ntawm qhov chaw ntawm lub rooj tsavxwm Circuit Court (SMD lossis Surface Mounted Device) tsuas yog ib hom LED tshwj xeeb xwb. Lub npe feem ntau los ntawm txoj kev uas lub nti tau ntim thiab muab tso rau ntawm lub rooj tsavxwm.

Tam sim no, kev lag luam teeb pom kev zoo yog dominated los ntawm ob txoj hauv kev tseem ceeb ntawm kev ntim cov teeb no:

● LubSMD Txoj Kev: Txoj kev no tau hloov pauv kev lag luam tag nrho vim nws ua rau kev tsim khoom ntau ntau ua tau zoo heev. Nws tso cai rau ntau yam kev xaiv xim.

● LubCOB Txoj Kev: Ua lwm txoj hauv kev ua haujlwm siab, cov chaw tsim khoom tau pib teeb tsa ntau lub teeb sib txuas ua ke ncaj qha rau ntawm ib lub hauv paus (Chip-on-Board, lossis COB). Tus qauv tsim no muaj nqis heev vim nws tsim kom muaj qhov kaj dua thiab muaj zog dua.

Hauv tsab xov xwm no, peb yuav piv ob lub thev naus laus zis thiab saib seb qhov twg yog qhov kev xaiv zoo tshaj plaws rau ntau daim ntawv thov sib txawv.

Kev Nkag Siab Txog SMD LED Technology

Yuav Ua Li Cas Lub Teeb Thiaj Li Tau Tsim

Cov teeb no yog ua los ntawm kev txuas cov teeb me me ncaj qha rau ntawm qhov chaw hu ua Printed Circuit Board, lossis PCB. Lawv tsis siv cov ceg hlau qub uas hla dhau lub rooj tsavxwm thiab xav tau kev sib txuas nyuaj.

Hloov chaw, cov tshuab muab cov khoom tso rau ntawm qhov chaw sai sai siv Surface-Mount Technology, lossis SMT. Qhov no tso cai rau kev tsim khoom sai thiab meej heev. Cov khoom raug xauv tas mus li siv cov txheej txheem cua sov uas yaj cov hlau rau cov khoom sib txuas. Cua sov thiab siab khi cov khoom rau cov ntsiab lus sib txuas ntawm lub rooj tsavxwm hu ua solder pads. Txhua lub teeb me me feem ntau tuav ib mus rau peb lub teeb-emitting diodes. Cov no feem ntau yog liab, ntsuab, thiab xiav. Lawv txhua tus nyob hauv ib lub thawv yas.

Kev Ua Tau Zoo thiab Kev Tsim Khoom Zoo

Raws li kev nkag siab hauv kev lag luam, kev siv cov tshuab tsis siv neeg los tsim teeb nrog cov ICs sib xyaw ua ke yog qhov ua tau zoo heev. Txoj kev no ua tiav qhov kev tsim khoom zoo tshaj 99.5%. Qhov no yog kev txhim kho loj dua 92% cov txiaj ntsig pom hauv cov txheej txheem cua sov txheem.

Cov modules siab heev no kuj ceev heev. Lawv tuaj yeem hloov lawv qhov ci ntsa iab lossis lub sijhawm teb tsis ci ntsa iab hauv qab 100 nanoseconds. Qhov ceev no yooj yim dhau qhov kev npaj analog txheem. Lawv siv hluav taws xob zoo heev rau lawv qhov me me. Cov qauv muaj zog siab, xws li 5730, muab lub teeb ci ntsa iab rau lub zog siv. Lawv tuaj yeem muaj qhov ua tau zoo txog li 240 lumens ib watt.

Kev Ua Haujlwm Zoo Dua

Txawm hais tias lub teeb pom kev niaj hnub no tau nce qib heev, nws tseem ntsib qee qhov kev txwv ntawm lub cev. Tej zaum koj yuav xav tias kev pub hluav taws xob ntau dua rau hauv lub teeb yuav ua rau muaj qhov ci ntsa iab ntau dua. Txawm li cas los xij, qhov tseeb, qhov ntau ntawm lub teeb uas tsim tawm ib watt yeej txo qis thaum koj thawb ntau lub zog hluav taws xob. Qhov xwm txheej no hu ua kev ua haujlwm poob qis. Qhov ua rau poob qis hauv kev ua haujlwm yog ib qho txheej txheem atomic tshwj xeeb hu ua Auger recombination. Hauv qhov xwm txheej zoo li no, lub zog raug pov tseg sab hauv es tsis yog tso tawm ua lub teeb.

Cov yam ntxwv tseem ceeb ntawm kev tsim qauv thiab cov zis pom

Cov teeb no muaj ntau yam siv tau thiab muaj ntau qhov ntau thiab tsawg. Cov qauv feem ntau suav nrog 2835, 3528, thiab 5050. Cov lej no tsuas yog hais txog lawv qhov loj me hauv millimeters. Piv txwv li, 2835 txhais tau tias yog 2.8 hli los ntawm 3.5 hli loj. Vim tias ntau lub teeb tau ntim rau hauv ib lub thawv, lawv yooj yim tsim ntau xim lossis RGB (Liab, Ntsuab, Xiav) tso zis. Cov txheej txheem tswj niaj hnub tso cai rau kev tswj hwm txhua lub ntsiab lus me me ntawm lawv tus kheej.

Lawv ua haujlwm ua cov teeb ci ntsa iab lossis cov teeb ci taw tes. Qhov no ua rau lawv ci heev. Txawm li cas los xij, yog tias koj saib lawv ntawm qhov ze, koj yuav pom cov teeb ci thiab pixelation. Feem ntau ntawm cov teeb no nthuav lawv lub teeb dav dav, feem ntau ntawm lub kaum sab xis ntawm 140 ° thiab 160 °. Txawm li cas los xij, qee qhov tshwj xeeb thawb lub teeb tawm mus rau sab, sib luag rau ntawm lub rooj tsavxwm. Cov no siv rau hauv cov ntxaij vab tshaus nyias nyias. Cov teeb no yooj yim kho. Yog tias ib lub teeb hlaws tsis ua haujlwm, koj feem ntau tuaj yeem hloov pauv daim ntawd. Koj tsis tas yuav pov tseg tag nrho cov module.

Tshawb Nrhiav COB LED Technology

Yuav ua li cas COB Teeb tau tsim

Tus qauv COB siv txoj hauv kev txawv ntawm cov qauv qub. Tsis txhob muab txhua lub teeb rau nws tus kheej lub tsev thiab cov hlau leadframes, nws txuas ntau lub teeb liab qab ncaj qha rau ntawm ib txheej puag. Nws zoo heev ntawm kev kos cov cua sov, zoo li ceramic lossis silicon carbide.

Nws tso cai rau cov chaw tsim khoom muab cov teeb pom kev zoo dua piv rau SMD teeb. Tag nrho cov chips ces npog nrog ib txheej du ntawm cov khoom siv phosphor tshwj xeeb. Nws hloov lub teeb xiav nyoos mus rau hauv qhov kub dawb sib xws. Txawm hais tias muaj ntau lub diodes, qhov teeb tsa hluav taws xob yog qhov yooj yim heev. Nws tsuas yog siv ib txoj kev hluav taws xob thiab ob lub ntsiab lus sib txuas.

Kev Nkag Siab Txog Kev Txhais Lus Siab thiab Kev Tswj Xyuas Kub

Raws li kev nkag siab ntawm kev lag luam, txoj kev teeb tsa ncaj qha no tso cai rau cov teeb me me kom muab tso ze heev ua ke. Lub pixel pitches (qhov sib txawv) ntawm cov teeb no tuaj yeem zoo li P0.4. Qhov ze heev no yog qhov tsim nyog rau kev tsim cov zaub ultra-high-definition 4K thiab 8K.

Lwm qhov kev nkag siab qhia txog qhov zoo ntawm kev kub. Vim tias cov chips raug txuas ncaj qha rau lub hauv paus siv cov kua nplaum thermal, qhov thaiv uas ntxiv kev tiv thaiv thermal raug txo qis. Qhov no tso cai rau cov cua sov kom ntws sai thiab yooj yim ntawm lub teeb thiab mus rau hauv lub dab dej kub sab nraud.

Qhov Zoo ntawm Kev Pom thiab Kev Xis Nyob

Cov duab ntawm cov teeb no ua rau lawv ua haujlwm zoo li lub teeb ntsa iab dua li cov teeb me me. Nws tsim cov teeb mos mos thiab du uas tshem tawm cov duab ntxoov ntxoo hnyav. Nws ua rau cov teeb pom kev zoo li "dotted" ntawm cov teeb qub qub tsis siv lawm. Lub teeb du yog qhov zoo tagnrho rau kev teeb tsa kev tshaj lij vim nws yooj yim rau lub qhov muag txawm tias siv ntev lawm.

Cov thev naus laus zis kuj tau tso cai rau kev siv cov chips tshwj xeeb. Qhov kev txhim kho no ua kom lub teeb tseem ci thiab pom tseeb txawm tias thaum saib los ntawm cov ces kaum siab heev, nrog rau lub kaum sab xis saib tas li ntawm 170 degrees.

Kev Ruaj Khov thiab Kev Ntseeg Tau

Tus qauv tsim uas ruaj khov thiab txhua yam hauv ib qho muab kev tiv thaiv zoo heev rau lub ntiaj teb sab nraud. Cov chav no tiv taus cov teeb meem xws li xuab zeb thiab dej nkag. Feem ntau lawv muaj qib IP65 txog IP68. Vim tias cov chips tau muab kaw tag nrho, lawv lub peev xwm los tiv taus kev cuam tshuam yog muaj zog txog li tsib zaug dua li cov teeb SMD. Qhov no ua rau lawv ntseeg tau heev hauv thaj chaw uas muaj neeg coob coob thiab muaj neeg coob.

Ib qho kev nkag siab txog kev lag luam qhia tau tias lawv ntseeg tau npaum li cas. Tus naj npawb ntawm cov chav ua tsis tiav ntawm ib lab (Failure Rate lossis ppm) rau cov modules no feem ntau tsawg dua 50 ppm. Qhov sib piv, cov hlaws teeb SMD ib leeg feem ntau ua tsis tiav ntawm tus nqi ntawm 200 txog 500 ppm.
