Lub sijhawm no, cov tuam ntxhab tuaj yeem khav tau ntawm lub loj loj kev ua haujlwm ntawm LED strips. Txhawm rau kom yooj yim rau lawv txoj kev txhim kho, cov tapes yog ua rau ntawm lub nplaum-npog puag. Cov kab hluav taws xob LED yog siv ob qho tib si rau kev teeb pom kev zoo ntawm nthab thiab rau txhua hom niches.
Hom raj xaj los ntawm hom LED
Daim iav LED niaj hnub muaj ntau hom ci:
- Liab, - xiav, - daj
- ntsuab, - kev sib xyaw ntawm daj thiab dawb.
Los ntawm txoj kev, tsis muaj qhov tseeb xim dawb hauv lub spectrum, yog li cov xim txias sib txuam monochromatic ci tau txais siv cov xiav LED them nrog phosphor txheej, thiab ib qho xim zas yog siv rau lub suab nrov sov.
Cov kab hluav taws xob LED tau muab faib ua raws li hom LEDs siv nyob rau hauv cov kab txaij, lawv qhov ntom ntom ntom (suav hais tias cov naj npawb ntawm LED nyob rau ib ntu ntawm cov kab txaij), lub zog (ntsuas hauv ວັດ), qhov ntsuas kev tiv thaiv kev ya raws thiab xim ci.
Hom ntawm diodes
Txhawm rau kom tau txais cov xim LED ib leeg, ob hom tseem ceeb ntawm LEDs siv - SMD 3028 thiab SMD 5050.
SMD 5050 muaj peb lub muaju thiab ci ntsa iab dua SMD 3028. Cov tsiaj ntawv Latin SMD yog cov tsiaj ntawv luv rau lus Askiv thiab txhais ua "nto mounted ntaus". Cov lej hauv qab no qhia qhov ntev ntawm lub diodes, ntsuas hauv millimetres (piv txwv, 3028 - qhov loj ntawm LED yog 3 hli los ntawm 2.8 hli).
Los ntawm tus naj npawb ntawm LEDs ib 'meter' (los ntawm ntom ntom), tapes tau muab faib:
- SMD 3028 rau 60, 120 thiab 240 diodes ib 'meter', - SMD 5050 rau 30, 60 THIAB 120 diodes ib 'meter'.
Qhov ntau ntawm tus naj npawb ntawm LED nyob rau hauv sawb, ntau zog thiab ci nws yog.
Cov strips LED tuaj yeem sib txawv ntawm lwm tus tsis yog hauv tus lej ntawm diodes, tab sis kuj nyob rau lawv qhov loj me. Qhov no cuam tshuam ncaj qha rau lub hwj chim. Yog li, ib txoj kab tawm ntawm SMD 3028, muaj 60 diodes ib 'meter', noj txog 4 watts, thiab ib qho kab ntawm SMD 5050, muaj tib lub ntsuas - 60 diodes ib 'meter', yuav twb haus tau 14,4 watts.
SMD 3028 sawb nrog 120 diodes ib 'meter' yuav tsum muaj lub zog ntawm 9.6 W, thiab tib lub SMD 3028 sawb, tab sis nrog 240 diodes ib 'meter', yuav xav tau 16,8 watts. Cov tsis xws li lub zog thiab ko taw muaj feem xyuam rau kev xaiv ntawm lub hwj chim.
Dej npog thiab cov ntaub qhwv rau txoj kev teeb pom kev zoo
Cov qib kev tiv thaiv ntawm cov kab hluav taws xob LED pl thaiv tawm tsam qhov cuam tshuam tsis zoo - dej thiab lwm yam kev nkag mus - muaj raws cov qauv thoob ntiaj teb. Ua raws li cov qauv no, cov kab xev yog tsim los ntawm qhov ntsuas - IP.
IP 20 - qhib hom LED sawb, nws yog siv rau hauv cov chav uas tsis muaj qhov yuav tsum tau ntxiv rau nws kev tiv thaiv los ntawm ya raws (chav pw lossis chav tsev).
IP 65 - ntaub nplaum dej. Hom no yooj yim rau kev siv hauv chav dej, chav ua haujlwm hauv chaw ua noj, tshwj tsis yog nws tuaj yeem siv rau txoj kev teeb pom kev zoo.
IP 68 - cov kab xev yog tiv thaiv tag nrho los ntawm kev ya raws, nws tuaj yeem muab tso rau hauv dej kom tob txog 1 meter thiab nws tseem tuaj yeem khov.
Tsis ntev los no, RGB tapes tau dhau los ua ntau. Lawv qhov peculiarity yog tias lawv tsis txwv rau ib qho xim, tus maub los, raws li qhov kev thov ntawm tus tswv, tuaj yeem muab cov xim monochrome, tab sis tuaj yeem ua rau cov pob tw ci nrog yuav luag txhua xim ntawm zaj sawv.
