Yuav ua li cas xaiv 2835 SMD LED?
SMD LEDs yog affixed rau saum npoo ntawm lub rooj tsavxwm Circuit Court, haum rau SMT ua, thiab yuav tsum reflowed. SMD LEDs daws teeb meem ntawm qhov ci, saib lub kaum ntse ntse, flatness, kev ntseeg tau, thiab sib xws. Piv nrog rau lwm cov khoom ntim, nws muaj qhov zoo ntawm qhov muaj zog vibration tsis kam, tsis tshua muaj kev sib koom ua ke tsis zoo, thiab cov yam ntxwv zoo siab. Nws encapsulates ntau LED chips nyob rau hauv ib tug me me cheeb tsam, siv sib dua PCB thiab reflective txheej ntaub ntawv, thiab qhia tau hais tias lub reflective txheej yuav tsum tau sau. Muaj tsawg dua epoxy resin. Los ntawm kev tshem tawm cov khoom hnyav carbon steel pins thiab txo qhov loj, qhov hnyav ntawm cov khoom tuaj yeem txo tau yooj yim los ntawm ib nrab. Qhov ntim thiab qhov hnyav tsuas yog li 1/10 ntawm cov tsoos plug-in Cheebtsam. Tom qab siv SMD ntim, ntim ntawm cov khoom siv hluav taws xob raug txo los ntawm 40% mus rau 60%, thiab qhov hnyav txo los ntawm 60% mus rau 80%, uas thaum kawg ua rau daim ntawv thov zoo dua.
Cia's ua tib zoo saib ntawm kev siv SMD LED teeb hlaws: LED loj-screen qhia, teeb pom kev zoo, kho kom zoo nkauj, khoos phis tawj, cov khoom ua si hluav taws xob thiab khoom plig, keyboards, xov tooj, tshaj tawm, tsheb teeb, cov khoom ua si taw qhia tuav thiab ntau qhov chaw tsim khoom. Yog li yuav ua li cas kom paub qhov txawv qhov zoo thiab qhov tsis zoo ntawm LED SMD teeb hlaws?
1. Qhov sib txawv ntawm lub teeb hlaws cov khoom siv: tam sim no muaj txhuas brackets, tooj dag brackets, tooj liab brackets, thiab lwm yam nyob rau hauv kev ua lag luam, aluminium brackets pheej yig, tooj liab brackets yog kim, thiab tus nqi sib txawv yog ntau tshaj kaum npaug. Txawm tias tooj liab stents, tus nqi ntawm cov nyiaj plating kuj txawv. Kev lag luam feem ntau hu lawv cov stents zoo, thiab lawv feem ntau yog ua los ntawm tooj dag thiab nyiaj plating.
2. Qhov sib txawv ntawm cov khoom siv hlau sib txuas: Cov nti thiab lub bracket txuas nrog kub hlau vuam txoj kev. Tam sim no, muaj ob hom alloy hlau thiab ntshiab kub hlau nyob rau hauv kev ua lag luam. Ntshiab kub hlau yog zoo. Lanjin Optoelectronics siv cov xov hlau kub ntshiab kom muab faib ua 0.7, 0.9, 1.0, 1.2, thiab lwm yam raws li qhov tuab. Qhov tuab ntawm cov hlau kub, qhov qis ntawm cov cua sov pab pawg thiab lub neej ua haujlwm ntev dua. Txhua yam koj yuav tsum paub yog cov khoom siv thiab txoj kab uas hla ntawm cov hlau kub.
3. Qhov sib txawv ntawm cov nti loj: Cov nti loj feem ntau tshaj tawm hauv mils. Yog tias tsis muaj lub tshuab ntsuas lub zog siab, nws feem ntau nyuaj rau kev paub qhov txawv. Qhov loj dua lub nti, qhov ci dua. Peb tuaj yeem sib piv cov nti loj los ntawm kev xam qhov chaw nti. Piv txwv li, 23X10, lub nti cheeb tsam yog 230 square mils. Nws yog ib txoj hauv kev zoo los siv thaj chaw nti kom paub qhov txawv ntawm cov nti.
4. Xim sib cais, ib nrab siab thiab spectroscopy specifications:
(1) Kev sib cais xim: nws yog xim kub kev faib tawm, xws li 3200K-3350K raws li thawj cov ntaub ntawv, lub chaw ntim khoom tsis tu ncua yuav muab BIN code ntawm cov xim kub, qhov me me ntawm cov xim kub, qhov zoo dua, cov xim me dua. Kev faib tawm qhov kub thiab txias, xim ntawm lub teeb ci zoo sib xws.
(2) Voltage faib: Nws yog qhov kev faib hluav taws xob ntawm cov nti, xws li 3.0V-3.15V. Rau cov teeb pom kev zoo yog txuas nrog hauv series thiab sib npaug, qhov sib faib hluav taws xob yog tswj tsis pub dhau 0.15V, kom qhov kev faib tawm tam sim no ntawm lub teeb pom kev zoo sib xws, uas muaj txiaj ntsig zoo los txhim kho lub teeb ci lub neej.
(3) Lub teeb pom kev zoo: lub teeb ci ntawm lub teeb hlaws tau muab faib ua cov bins, muaj lumen bins los yog lub teeb siv lub bins, rau lub teeb pom kev zoo, lub lumen bins yog siv. Nws raug nquahu kom yuav cov LEDs raws li lub teeb pom kev zoo. Tsuas yog cov khoom uas muaj lub teeb pom kev zoo yuav txuag tau lub zog thiab muaj lub neej ntev.
5. Qhov txawv ntawm phosphor: Lub teeb dawb lub teeb hlaws yog ua los ntawm xiav nti thiab daj phosphor. Cov phosphor feem ntau muab faib ua aluminate thiab silicate. Kev ua haujlwm ntawm aluminate zoo dua li silicate. Tus neeg sawv cev ntawm aluminate yog YAG. YAG muaj kev ua haujlwm ruaj khov thiab tsis muaj teeb pom kev zoo. Cov tshuaj lom neeg ruaj khov ntawm silicate nws tus kheej tsis zoo, tab sis qhov ci ntsa iab siab dua YAG. Kuv xav ua cov khoom nrog kev ua haujlwm ruaj khov. , Tsis txhob dag los ntawm qhov hu ua siab ci, qhov no yog qhov teeb meem loj.
6. Qhov sib txawv ntawm cov kua nplaum: Phosphor yog yuav tsum tau tov nrog cov kua nplaum thiab muab tso rau hauv nti. Qhov zoo ntawm cov kua nplaum cuam tshuam rau lub teeb lwj thiab xim drift. Cov kua nplaum tsis zoo yuav daj thiab ua kom lub teeb lwj. Cov kua nplaum zoo Nws's jelly gum.
7. LED nti electrode daim ntawv qhia: Cov chaw tsim khoom sib txawv muaj qhov sib txawv LED zoo. Cov neeg muab khoom siv LED yuav lees paub tias lawv cov hlaws teeb LED tau ntim nrog cov cim npe. Tom qab lub teeb dawb LEDs tau ntim, nws yog tsis yooj yim sua los txiav txim lub nti chaw tsim tshuaj paus los ntawm cov tsos. , Cov nti yuav tsum tau muab tshem tawm thiab tshuaj xyuas hauv qab lub tshuab hluav taws xob muaj zog.
