Muaj ntau yam khoom siv saum npoo av (SMD) ntau yam muaj rau LED teeb pom kev zoo, txhua tus uas raug xaiv los ntawm plaub tus lej -. Qhov dav ntawm lub thawv yog qhia los ntawm thawj ob tus lej, thaum nws qhov ntev yog qhia los ntawm ob tus lej kawg. Kev ua tau zoo thiab cov yam ntxwv ntawm LED teeb pom kev zoo tau cuam tshuam los ntawm cov SMD ntau yam.SMD 2835 thiab SMD 3030yog ob qho ntawm feem ntau ua haujlwm. Piv txwv li, SMD qhov ntev ntawm 3030 LED sawb yog 3.0mm x 3.0mm. Kab lus no yuav qhia txog qhov sib txawv ntawm SMD 2835 thiab SMD 3030, tshuaj xyuas lawv cov kev qhia tshwj xeeb, kev siv, thiab cov txiaj ntsig.
SMD 2835 thiab SMD 3030 yog dab tsi?
SMD txhais li cas?
Cia peb nkag siab ua ntej SMD yog dab tsi ua ntej peb nkag mus rau hauv qhov tshwj xeeb. SMD stands rau "surface mount device," uas yog ib qho hluav taws xob uas tau tsim los txuas ncaj qha rau PCB qhov chaw. Ntau yam khoom siv hluav taws xob sib txawv siv SMD qhov chaw, xws li LED teeb pom kev zoo.
Nrog SMD LEDs, koj tuaj yeem tso lub teeb me me -emitting diode txoj cai ntawm PCB yam tsis muaj kev coj lossis xaim. Cov neeg nyiam lawv vim lawv me me, ci ntsa iab, thiab siv lub zog me me.
SMD 2835 txhais li cas?
SMD 2835 yog 2.8mm x 3.5mm LED nti uas zoo li tus duab plaub. Tsuas muaj ib qho LED nti hauv txhua chav vim nws yog ib qho -chip LED pob. Cov chips no feem ntau siv hauv cov khoom siv teeb pom kev zoo LED vim lawv ua haujlwm zoo, pheej yig, thiab ua haujlwm tau zoo. Hauv LED strips, teeb pom kev zoo, thiab lwm yam khoom siv teeb pom kev zoo uas xav tau ntau qhov me me, siv tau zoo, qhov style no yog nrov. Ntau zaus, SMD 2835 chips pheej yig dua qhov loj dua, muaj zog dua LED chips vim tias lawv yooj yim dua thiab tsis siv ntau qhov chaw.
SMD 3030 txhais li cas?
SMD 3030 yog 3.0mm x 3.0mm square LED nti. Nws yog ib lub pob -chip LED uas muaj ob peb LED chips nyob rau hauv ib chav tsev, muab tso rau hauv ib daim phiaj qauv ntawm lub hauv paus los txhim kho lub teeb tso zis thiab efficiency. Vim tias lawv siv sijhawm ntev, siv lub zog me me, thiab tsim lub teeb ntau, SMD 3030 LEDs feem ntau siv ntau yam khoom siv teeb pom kev zoo, los ntawm kev lag luam mus rau txoj kev dej nyab mus rau lub teeb pom kev zoo hauv tsev.
SMD 2835 VS. SMD 3030: Nta thiab Specifications
SMD 2835 thiab SMD 3030yog cov LED SMD tshaj plaws. Peb mam li muab piv rau ob hom SMD cov yam ntxwv thiab cov kev qhia tshwj xeeb los pab koj xaiv.
Cov peev txheej
LED thaj ua rau thaj 'zoo thiab durability nyob ntawm lawv cov khoom. 2835 nti siv PCT bracket, qhov 3030 siv EMC bracket. EMC brackets yog tsim los ntawm kev tuag- sab saum toj mus kom ze, uas yog pheej yig dua, tab sis cov khoom siv PCT muaj dej tsis zoo, ua rau kev txhaj tshuaj molding nyuaj thiab yuav tsum tau stamping. EMC tuaj yeem tau txais 3W, qhov PCT tsuas tuaj yeem tau txais 1W. Yog li ntawd, 3030 nti tau zoo thermal conductivity thiab kub tsis kam tshaj 2835 nti.
Kev ntsuas
SMD LED loj yog qhov tseem ceeb rau kev teeb tsa thiab kev sib raug zoo nrog cov teeb pom kev zoo tam sim no.
SMD 2835 LEDs yog me me piv rau lwm hom SMD, nrog rau cov duab plaub loj ntawm 2.8 × 3.5 hli. Compact thiab hloov tau, SMD 2835 LEDs yuav siv tau rau hauv ntau daim ntawv thov teeb pom kev zoo.
Hauv kev sib piv, SMD 3030LED loj dua ntawm 3.0 x 3.0 mm square. Lawv muaj kev ua kom txias thiab tswj fais fab zoo dua tab sis siv ntau qhov chaw.
Qhov txawv yuav tshwm sim me ntsis, tab sis nws yuav cuam tshuam rau qhov chaw - txwv tsis pub siv.
Kev siv zog
SMD 2835 paub txog nws qhov kev siv hluav taws xob tsawg. Lawv siv tsawg zog thiab ua haujlwm ntawm qhov hluav taws xob qis dua li lwm yam SMDs. Qhov no ua rau lawv zoo tagnrho rau lub zog- teeb pom kev zoo. Vim tias lawv qhov loj thiab qhov ci ci, SMD 3030 LEDs yuav xav tau hluav taws xob ntau dua.
PCT brackets muaj kev cuam tshuam ntau dua li EMC. Feem ntau siab -kev ua haujlwm mining thiab muaj teeb pom kev zoo, suav nrog 200 lm / W hom, siv 2835 chips.
Teeb pom kev zoo
Luminosity efficiency yog lub teeb generated rau ib chav tsev ntawm lub hwj chim. Qhov no yuav tsum tau txiav txim siab thaum ntsuas LED teeb.
Vim nws 120-150 lumens ib watt (lm / W) luminous efficiency, SMD 2835 tuaj yeem hloov hluav taws xob rau hauv lub teeb. tsim ntau lub teeb rau nws qhov loj thiab lub zog.
Vim nws lub siab luminous efficiency (150–180 lm / W), SMD 3030 LEDs hloov hluav taws xob rau hauv lub teeb zoo dua SMD 2835 LEDs. Vim lawv qhov loj me, lawv haum rau cov teeb pom kev nyab xeeb thiab siab - lub zog LED qhov muag teev.
Kub poob
LED teeb 'lub neej thiab kev ua haujlwm nyob ntawm qhov kub dissipation. Yog tias lub LED ua kom sov ntau dhau yam tsis muaj kev cuam tshuam txaus, nws txoj sia thiab kev ua haujlwm yuav raug kev txom nyem. SMD 3030 LEDs dissipate tshav kub zoo dua 2835 LEDs. SMD 3030 lub pob loj loj tuaj yeem txhim kho cov cua sov dissipation, txo LED kev ua haujlwm kub thiab nce lub neej. SMD 2835's ceramic puag tau zoo hloov hluav taws xob los ntawm LED nti, ua kom ruaj khov thiab ua haujlwm ntev.
Xim rendering index
Lub teeb qhov chaw xim xim rendering Performance index (CRI) piv rau lub teeb ntuj los txiav txim seb nws ntes cov khoom xim zoo li cas.
Higher CRI is possible with SMD 2835 LEDs, up to 95. Standard CRI is Ra>80, thiab xim kam rau ua<5. This shows their excellent color rendering. Ideal for art galleries and shops that need accurate color representation. SMD 3030 LEDs have a CRI of 70–90.
Cov chaw thov
SMD 2835 LEDs yog siv nyob rau hauv LED qhov muag teev, sawb teeb, downlights, vaj huam sib luag teeb, bay teeb, LCD npo backlighting, signage, thiab tsheb illumination vim nws compact loj thiab tsawg zog noj.
