Ua kom muaj kev nyab xeeb hauvHigh -Voltage Driverless LED Sawb: Rwb thaiv tsev thiab kev tsim qauv
Kev siv lub siab -voltage (110V / 220V AC) tsav tsheb tsis muaj LED strips, xws li cov siv SMD2835 LEDs, muaj cov txiaj ntsig zoo hauv kev yooj yim ntawm kev teeb tsa thiab ntev - teeb pom kev deb. Txawm li cas los xij, kev siv cov kev hloov pauv tam sim no ntawm qhov txaus ntshai voltage ncaj qha rau ntawm qhov hloov pauv hloov pauv yuav tsum muaj kev ruaj ntseg engineering kom tsis txhob muaj hluav taws xob poob siab, tshwj xeeb tshaj yog thaum txiav, txuas, thiab tuav. Cov ntaub ntawv rwb thaiv tsev tshwj xeeb thiab cov qauv tsim ua haujlwm yog qhov tseem ceeb thiab muaj ntau yam, tsim kom muaj kev nyab xeeb zoo.
1. Multi- Txheej Txheej Txheej Txheej Txheej
Qhov kev tiv thaiv tseem ceeb tiv thaiv hluav taws xob yog qhov muaj zog, ntau- cov txheej rwb thaiv tsev tsho uas npog tag nrho cov ntawv luam tawm Circuit Board (PCB) thiab cov khoom siv hluav taws xob.
Dual - Txheej PVC Jacket:Feem ntau siab - cov strips zoo siv aob - rwb thaiv tsevPVC lub tes tsho. Cov txheej sab hauv yog tsim los rau siab dielectric zog, ncaj qha insulating cov nyob conductors. Cov txheej txheej txheej yog tsim los rau kev ua haujlwm ntev, muab kev tiv thaiv rau kev puas tsuaj, cuam tshuam, UV hluav taws xob (rau kev siv sab nraum zoov), thiab tshuaj lom neeg. Qhov ob txoj hauv kev - txheej txheej no ua kom ntseeg tau tias yog tias txheej txheej txheej yog khawb los yog nicked thaum lub sijhawm teeb tsa, cov txheej sab hauv tseem nyob ruaj khov raws li qhov cuam tshuam txhim khu kev qha. Cov khoom siv PVC nws tus kheej feem ntau yog hluav taws kub - retardant (ua raws li cov qauv zoo li UL94 V-0) los tiv thaiv cov nplaim taws.
Potting lossis Encapsulation (rau IP Rated Strips):Rau IP65, IP67, lossis siab dua, cov sawb tau dhau los ua txheej txheem potting. Tom qab cov LEDs tau nruab rau ntawm PCB thiab lub tes tsho thawj zaug tau thov, tag nrho lub rooj sib txoos tau ntim nrogsilicone gel los yog epoxy resin. Cov khoom no encapsulates tag nrho cov khoom siv -LEDs, resistors, thiab tag nrho ntev ntawm tooj liab conductors. Nws tshem tawm cov hnab tshos huab cua, tiv thaiv kev ya raws thiab muab qhov tshwj xeeb ntawm kev cais hluav taws xob. Txawm hais tias lub tes tsho sab nrauv raug cuam tshuam, lub potting compound ua raws li cov dej tsis sib haum thiab insulating barrier.
2. Lub hauv paus: Lub Rooj Tswjhwm Saib Circuit Court (PCB)
Kev tsim ntawm PCB nws tus kheej yog ib feem tseem ceeb ntawm cov tswv yim kev nyab xeeb.
Thickened Copper Clad Laminate (CCL):Cov khoom siv hauv paus yog FR-4 fiberglass substrate clad nrog athickened tooj liab txheej(piv txwv li, 2-4 oz piv rau tus qauv 1 oz). Qhov no ua haujlwm rau ob lub hom phiaj: ua ntej, nws txo cov hluav taws xob tiv thaiv, txo qis hluav taws xob poob qis dua kev khiav mus ntev thiab tsim hluav taws xob (qhov chaw ntawm rwb thaiv tsev degradation); thib ob, nws muab ntau dua txhua yam kev ruaj ntseg, txo qhov kev pheej hmoo ntawm kev tawg thaum lub sij hawm flexing los yog installation.
Wide Spacing thiab Layout:Circuit Court layout yog tsim nrognce creepage thiab clearance nrugnruab nrab ntawm AC kab. Qhov no tiv thaiv qhov muaj peev xwm ntawm arcing hla cov conductors, ib qho kev xav tseem ceeb thaum lub sawb raug txiav, nthuav tawm tus ntoo khaub lig-section.
3. Kev nyab xeeb hauv kev txiav thiab kev sib txuas: Cov yam ntxwv ua haujlwm
Lub sijhawm txaus ntshai tshaj plaws tshwm sim thaum lub sawb raug txiav lossis txuas nrog. Cov neeg tsim khoom hais qhov no nrog kev tsim qauv tsim.
Ua ntej-Cov ntsiab lus txiav txiav:Strips raug cim ntawm lub sijhawm meej (piv txwv li, txhua 5 lossis 10 LEDs) uas sib haum rau qhov taw tes hauv AC lub voj voog uas lub voj voog muaj kev nyab xeeb rau sever. Ntawm cov ntsiab lus no, cov ntaub qhwv tooj liab yog tsim los cais tawm ntawm cov kab tseem ceeb tom qab txiav.
Insulated, Sealed Connectors:Proprietary pin connectors tsis yog rau hluav taws xob tiv tauj xwb; lawv tsim raws liinsulated vaj tse. High- cov khoom sib txuas zoo ua kom muaj lub cev yas ntim tag nrho uas snap hla qhov kawg ntawm cov sawb, tiv thaiv cov ntaub qhwv cov tooj liab thiab muab cov kev ntxhov siab. Rau cov khoom siv tsis muaj dej tsis zoo, cov khoom sib txuas no suav nrog silicone gaskets thiab sealing caps, tswj tus IP ntsuas ntawm qhov chaw sib txuas.
Insulated Caps:Tom qab txiav, txhua qhov kawg uas tsis siv yuav tsum raug kaw kom zoo.PVC los yog silicone kawg hauyog muab, uas yog thawb mus rau lub sawb thiab feem ntau ruaj nrog cov nplaum los yog kev sib txhuam haum. Cov kaus mom no yog tsim los tiv thaiv kev khiav hauj lwm voltage, tiv thaiv kev sib tsoo.
4. Cov khoom tiv thaiv ntxiv
Tshaj li cov khoom siv lub cev, cov yam ntxwv kev nyab xeeb hluav taws xob tau muab tso ua ke.
Hauv -Line Fuses:Qee cov qauv tsim suav nrog me me, tus neeg siv - hloov fuse hauv lub hwj chim ntsaws. Qhov no tiv thaiv overcurrent thiab muaj peev xwm luv luv circuits.
Overmolding ntawm Plugs:Lub AC fais fab ntsaws yog hnyav heev, txhais tau hais tias lub cable nkag mus yog nyob ib puag ncig los ntawm cov yas tuab, tiv thaiv cov xov hlau los ntawm rub tawm thiab nthuav tawm.
Xaus: A System of Redundancy
Kev nyab xeeb ntawm siab -voltage LED strips tsis yog nyob ntawm ib qho tshwj xeeb tab sis ntawm aredundant, multi- txheej txheej. Kev sib xyaw ua ke ntawm cov khoom siv ruaj khov dual-txheej PVC lub tsho, lub PCB ruaj khov tuab, ua tiav cov dej tsis muaj dej, thiab tshwj xeeb tsim cov khoom siv insulated thiab cov kaus mom kawg ua rau muaj kev tiv thaiv zoo ntawm tus neeg siv thiab qhov txaus ntshai nyob rau hauv. Qhov kev qhia dav dav no tso cai rau cov teeb pom kev yooj yim no los nruab thiab ua haujlwm nrog kev ntseeg siab, yog tias cov neeg tsim khoom ua raws li cov chaw tsim khoom cov lus qhia, siv cov khoom siv tshwj xeeb, thiab ib txwm txiav lub hwj chim ua ntej ua cov txheej txheem txiav lossis kev sib txuas. Thaum kawg, lub tswv yim tsim qauv no ua kom ntseeg tau tias kev nyab xeeb yog qhov tseem ceeb, tsis yog kev xav tom qab.
