Kub Dawb SMD LED 2500k 2835
LED yog cov khoom siv tam sim no. Kev hloov pauv me ntsis ntawm qhov hluav taws xob yuav ua rau muaj kev hloov pauv loj ntawm tam sim no, uas yuav ua rau LEDs puas. Cov neeg siv khoom yuav tsum siv cov resistors hauv series rau Over-Current-Proof.
Txhawm rau kom ntseeg tau tias lub teeb-xim zoo sib xws ntawm ntau lub LEDs txuas nrog nyob rau hauv parallel, tus neeg tiv thaiv ib leeg yog qhia, raws li Circuit A hauv qab no qhia. Yog hais tias lub teeb-xim ntawm txhua LED qhia raws li Circuit B yuav txawv vim qhov txawv IV yam ntxwv ntawm txhua LED.
Kev kub siab ambient kub yuav cuam tshuam rau qhov ci ntawm LED thiab nws cov khoom, thov kom deb ntawm qhov kub kom ua tau zoo dua.
Cia:
Kev pom zoo cia ua ntej unpacking: Kub: 5 degree ~ 30 degree; Humidity: qis dua 60 feem pua RH. Dehumidification yuav tsum tau ua ua ntej siv thaum nws khaws cia rau ntau tshaj 2 lub hlis. Cov xwm txheej 60 degree / 12 teev.
Cov lus pom zoo cia yuav tsum yog kub hauv 5 ~ 30 degree, av noo hauv qab 30 feem pua tom qab qhib pob.
LED yog ib qho khoom siv uas nkag siab rau cov av noo, uas yuav tsum tau muab khaws cia rau hauv lub thawv ntim nrog cov desiccant lossis nitrogen noo-pov thawj txee kom tsis txhob ya raws tom qab ntim khoom.
Qhov ntsuas dej-pov thawj ntawm LED yog MSL3. Cheebtsam yuav tsum tau siv nyob rau hauv 168hrs (7 hnub) tom qab unpacking thiab welded sai li sai tau.
Cheebtsam yuav tsum dehumidified thaum nws raug rau huab cua ntau tshaj 168hrs (7 hnub) los yog desiccant tas sij hawm.
Kev tiv thaiv electrostatic:
Vim LED (tshwj xeeb tshaj yog xiav, daj ntsuab, ntshav, dawb, liab LED nyob rau hauv InGaN qauv) yog rhiab heev rau electrostatic uas yuav ua puas rau nws cov qauv, uas tej zaum yuav ua tau txawv txav tom qab raug tawm tsam los ntawm electrostatic los yog overload tam sim no, xws li ntau dhau los tam sim no. , VF qis lossis tsis tuaj yeem teeb pom kev zoo, thov nco ntsoov raws li hauv qab no.
Anti-static dab teg los yog cov hnab looj tes tiv thaiv zoo li qub yuav tsum hnav kom kov LED.
Rounding tiv thaiv yuav tsum tau ua rau tag nrho cov tshuab thiab cov cuab yeej cuab yeej, cov rooj ua hauj lwm, cov khoom racks, thiab lwm yam..(hauv 10Ω ntawm grounding impedance).
Anti-static hnab, anti-static box thiab anti-static turnover box yuav tsum tau siv rau cia los yog thauj. Tsis txhob siv cov yas.
Nws raug nquahu kom siv ion kiv cua txhawm rau txhawm rau tsim hluav taws xob hluav taws xob thaum lub sijhawm ua haujlwm.
Qhov Voltage ntawm static teb yog tsawg dua 100V hauv 1 ko taw vojvoog los ntawm LED tivthaiv.
