'Kuv xav tau hom tsav tsheb LED dab tsi?'Tshawb nrhiav rau cov tsav tsheb LED tuaj yeem yuav nyuaj dua li koj xav nrog ntau txoj kev xaiv tawm muaj. Muaj ntau ntau yam los saib thaum xaiv ib qho uas ua haujlwm zoo tshaj rau koj, peb muaj kev ua kom zoo los ntawm qhov no hauv peb phau ntawv qhia ntawm cov tsav tsheb LEDntawm noCov. Ib qho kev xaiv tseem ceeb yog kev xaiv ntawm tus tsav tsheb tam sim no LED tiv thaiv ib qho kev hloov pauv ntawm lub zog LED tsav tas mus li. Tam sim no, nws paub tias cov tsav tsheb LED raug suav hais tias yog cov khoom siv hluav taws xob tas li, yog li vim li cas cov tuam ntxhab muab cov hluav taws xob tsis xwm yeem rau LEDs zoo ib yam? Peb tuaj yeem qhia qhov txawv nruab nrab ntawm ob qho no li cas?

Tas Nrho Cov Tsav Tsheb LED Tam Sim No.

Cov tsav tsheb tsis tu ncua tam sim no thiab lub zog tas mus li yog ob qho kev xaiv uas muaj peev xwm rau lub zog hluav taws xob rau cov teeb pom kev ntawm LED, qhov sib txawv yog txoj hauv kev uas lawv xa lub zog. Cov tsav tsheb LED yog lub zog tsav uas muab thiab tswj hwm lub zog tsim nyog kom paub tseeb tias cov LED khiav lag luam nyob hauv kev nyab xeeb thiab zoo. Nkag siab qhov sib txawv ntawm ob hom tuaj yeem:

1. Pab hauv kev siv hluav taws xob kom zoo

2. Zam kev puas tsuaj loj rau koj kev nqis peev LED

Dab tsi yog Qhov Tas Nrho Cov Neeg Tsav Tsheb LED Yog Dab Tsi?

Cov tsav tsheb tsis tu ncua LED tam sim no yog tsim los rau cov tsim cov qhov tso tawm thiab hloov cov zis tam sim no (mA). Cov LEDs uas tau raug ntsuas kom ua haujlwm ntawm lub tshuab tsav tsheb tsis tu ncua uas yuav tsum tau muaj cov khoom tsim nyog tam sim no feem ntau tau teev tseg hauv milliamps (mA) lossis amps (A). Cov tsav tsheb sib txawv hloov qhov voltage raws hluav taws xob hluav taws xob uas tso cai rau tam sim no kom nyob twj ywm tas li thoob plaws hauv LED system.Txhais Tau Zoo Qhov AP Tas Nrho Tsav Tshebyog ib qho piv txwv zoo qhia hauv qab no:

Cov kev ntsuas siab dua tam sim no ua rau cov LED ci ntsa iab dua, tab sis yog tias tsis tau tswj raws cai, LED yuav kos tam sim no ntau dua li nws tau ntsuas rau. Thermal Khiav Kev khiav haujlwm hais txog qhov tam sim no dhau ntawm LEDs qhov siab tshaj plaws tsav tam sim no uas ua rau muaj hluav taws xob tsawg dua LED lub neej thiab qhov ua ntej hlawv tawm vim qhov kub nce. Tus tsav tsheb tsis tu ncua tam sim no yog qhov zoo tshaj plaws rau kev tsav tsheb muaj zog LEDs vim nws tswj qhov ci ntsa kom zoo thoob plaws txhua qhov chaw hauv LED.

Dab tsi Yog Cov Nqes Tus Hluav Taws Xob Tsav Tsheb LED?

Cov tsav tsheb hluav taws xob tas li yog tsim rau ib qho ncaj qha tam sim no (DC) cov zis hluav taws xob. Cov tsav tsheb hluav taws xob feem ntau tsis tu ncua (lossis Cov Khoom Siv Hluav Taws Xob) yog 12VDC lossis 24VDC. Ib lub teeb ci LED uas tau ntsuas rau qhov ntsuas hluav taws xob tas li feem ntau qhia meej qhov ntsuas hluav taws xob nws yuav tsum ua haujlwm kom raug.

Qhov hluav taws xob tsis tu ncua hluav taws xob tau txais cov qauv kab hluav taws xob (120-277VAC). Qhov no yog hom ntawm lub hwj chim uas feem ntau tsim tawm los ntawm koj phab ntsa thaiv phab ntsa ncig lub tsev. Tus tsav ntsuas hluav taws xob tas mus li hloov qhov hloov pauv tam sim no (VAC) mus rau qhov hluav taws xob qis tam sim no (VDC). Tus tsav tsheb yuav nco ntsoov tswj qhov hluav taws xob tas li tsis muaj teeb meem dab tsi ntawm cov khoom thauj tam sim no muab tso rau ntawm nws. Ib qho piv txwv ntawm cov hluav taws xob tas mus li lub zog hluav taws xob hauv qab no yog nyob hauvTxhais Tau Zoo LPV-60-12.

Qhov LPV-60-12 yuav tswj hwm tas mus li 12VDC yog qhov tam sim no qis qis dua 5-amp qhov siab tshaj plaws tau qhia hauv lub rooj. Feem ntau, cov hluav taws xob tas mus li siv nyob rau hauv cov txee rau hauv qab thiab lwm yamLED flex sawbdaim ntawv thov tab sis nws tsis txwv rau cov pawg ntawd.

Yog li kuv yuav ua li cas kuv thiaj paub hom LED tsav tsheb kuv xav tau?

Cov ntaub ntawv tam sim no yuam kev:

Yog tias koj ua tibzoo saib ntawm lub siab siv hluav taws xob LED, ib qho kev tshwj xeeb ntawm tus yam ntxwv yog qhov kev sib raug zoo ntawm kev siv hluav taws xob rau pem hauv ntej rau LED thiab qhov ntws tam sim no los ntawm nws. Koj tuaj yeem pom qhov no meej meej los ntawm cov yam ntxwv hluav taws xob ntawm Cree XP-G2 hauv qab no hauv daim duab 1. Thaum LED tig, txawm tias qhov tsawg tshaj plaws 5% hloov voltage (2.74V rau 2.87V) tuaj yeem tsim 100% nce rau tam sim no tsav mus rau XP-G2 raws li koj tuaj yeem pom ntawm lub teeb liab liab pom ntawm 350mA txog 700mA.

Daim duab 1

Tam sim no siab dua tam sim no puas ua rau cov LED ci ntsa iab dua, tab sis nws kuj yuav nws thiaj li dhau kev tsav tsheb ntawm LED. Saib Daim Duab 2 rau Cree qhov tshwj xeeb ntawm qhov siab tshaj plaws rau tam sim no thiab de-ntsuam xyuas nkhaus nyob rau hauv cov huab cua kub sib txawv. Hauv qhov piv txwv saum toj no peb tseem yuav yog qhov zoo tag nrho tsav lub XP-G2 LED ntawm 700mA, txawm li cas los xij, yog tias koj tsis muaj qhov kev txwv tam sim no, LED yuav kos ntau dua tam sim no vim nws cov hluav taws xob hloov vim qhov kub nce. Qhov no yuav thaum kawg thawb txoj kev tam sim no siab tshaj qhov kev txwv ... tshwj xeeb tshaj yog hauv cov chaw huab cua sov dua. Qhov dhau mus rau tam sim no yuav ua rau kub ntxiv nyob rau hauv qhov system, txiav tawm ntawm cov LEDs lub neej, thiab thaum kawg ua rau lub LED tawg. Peb hu qhov no thermal khiav tawm uas tau piav qhia hauv kev piav qhia ntau ntxivntawm noCov. Qhov no yog vim li cas qhov kev nyiam tshaj plaws ntawm lub zog hluav taws xob siab LED yog nrog cov hluav taws xob tsav LED tam sim no. Nrog cov khoom siv hluav taws xob tas li, txawm tias qhov hloov hluav taws xob nrog qhov ntsuas kub tus neeg tsav tsheb ua rau lub zog tsis hloov tam sim no tsis dhau tsav lub LED thiab tiv thaiv kev kub khiav.

Thaum twg kuv siv aconstant voltage LED tsav tsheb?

Qhov piv txwv saum toj no yog nrog siab LEDs muaj zog thiab ntawm cov nplai me me thaum peb tsuas yog hais txog kev siv ib qho LED xwb. Nrog rau lub teeb pom kev hauv lub ntiaj teb tiag, nws tsis yooj yim los yog yig los tsim txhua yam los ntawm txhais tes los ntawm ib leeg, di LED feem ntau siv ua ke hauv seriesand / lossis cov hluav taws xob sib luag los tsim cov txiaj ntsig uas xav tau. Hmoov zoo rau cov teeb pom kev zoo tsim, cov tuam ntxhab tau qhia ntau yam khoom lag luam LED tag nrho cov lag luam uas muaj ntau lub LEDs tau sib sau ua ke xws li cov hlua LED teeb, LED strips, LED tuav, thiab lwm yam.

Cov phiajcim LED ntau tshaj yog sib tshooj nrog ib pawg ntawm LED nyob rau hauv cov kab nrog cov tam sim no-txwv tsis pub tawm tsam nyob rau hauv txoj kab nrog lawv. Cov tuam txhab tsim kom paub tseeb tias cov resistors yog ntawm tus nqi tsim nyog thiab nyob hauv txoj cai zoo kom cov LEDs ntawm cov kab hluav taws xob yuav tsawg dua rau qhov sib txawv ntawm qhov ntsuas hluav taws xob thaum peb tau tham nrog lub XP-G2. Txij li lawv cov isalready tam sim no raug tswj, txhua yam lawv xav tau yog qhov hluav taws xob tas li los ua kom lub zog ntawm LED (s).

Thaum LEDs lossis ib qho teeb ci ntawm LEDs raug tsim ua qhov zoo li no lawv yuav feem ntau hais txog qhov voltage yuav tsum khiav ntawm. Yog li yog tias koj pom tias koj txoj hlua khi siv 12VDC, tsis txhob txhawj xeeb txog qhov chaw tsav tsheb tsis tu ncua, txhua yam koj yuav xav tau yog 12VDC qhov hluav taws xob qhov hluav taws xob raws li qhov tam sim no twb tau raug tswj los ntawm board Circuitry uas cov chaw tsim khoom tsim muaj.

Qhov zoo ntawm kev siv cov hluav taws xob tsav tsheb LED tam sim no

Yog li thaum koj tsim koj tus kheej qhov khoom lossis ua haujlwm nrog pebsiab zog LEDs, nws yog qhov zoo rau koj los siv cov tsav tsheb tsis tu ncua vim tias:

1. Lawv zam kom tsis txhob ua txhaum qhov siab tshaj plaws tam sim no rau cov LEDs, yog li zam kom tsis txhob hlawv / thermal khiav tawm.

2. Lawv yooj yim dua rau cov neeg tsim qauv los tswj cov ntawv thov, thiab pab tsim lub teeb ci nrog kev ci ntsa iab ntau dua.

Qhov zoo ntawm kev siv lub zog hluav taws xob tas mus li ntawm tus tsav tsheb LED

Koj siv qhov hluav taws xob tas li LED tsav tsheb thaum tsuas yog siv cov kab hluav taws xob LED lossis cov kab uas tau teev tseg los ntsuas qee qhov voltage. Qhov no yuav pab tau yog:

1. Qhov hluav taws xob tas li yog qhov paub dua ntawm cov thev naus laus zis rau cov qauv tsim thiab teeb tsa.

2. Tus nqi ntawm cov kab ke no tuaj yeem qis dua, tshwj xeeb hauv cov ntawv thov loj dua.

Xav tias dawb los saib ntawm pebqhia rau LED stripsuas muaj ntau lub cuab yeej uas tuaj yeem khiav los ntawm tas li voltage. Tsis tas li, yog tias koj xav tau kev pab xaiv qhov tsis tu ncua tsav tsheb LED tam sim no, lub taub hau rau peb cov txiaj ntsigtswgyuav ua li cas los xaiv qhov zoo.
