Tsis ntev los no, LEDs tau siv los ua qhov taw qhia rau / tawm rau ntau yam khoom siv hluav taws xob. Txawm li cas los xij, cov thev naus laus zis niaj hnub rau kev tsim cov xov tooj cua thiab cov khoom siv hluav taws xob tau nce los ntawm leaps thiab ciam teb. Tam sim no cov khoom siv zoo li no tau siv hauv ntau lub lag luam. Kev xaiv yog dav heev nyob rau hauv cov nqe lus ntawm tus naj npawb ntawm manufacturers thiab ntau yam kev hloov kho. Vim nws cov yam ntxwv siab, 2835 LEDs yog qhov dav siv los ntawm ntau lub tuam txhab ntawm lub zog txuag teeb rau ntau lub hom phiaj.

kos npe, piav qhia thiab tsim nta

Qhov ntsuas plaub tus lej hauv qhov cim qhia txog qhov ntev ntawm LED nti. Rau cov khoom siv 2835, lawv yog: ntev - 2.8 hli, dav - 3.5 hli, thickness - 0.8 hli.

Tsim thiab thev naus laus zis:

  • Lub tsev yog ua los ntawm cov yas tshwj xeeb uas tiv taus cua sov thiab txuas rau lub dab dej kub txhuas (0.25 hli tuab).
  • Ntau qhov hluav taws xob ntau ntxiv (piv rau cov analogues ntawm lwm cov koob, piv txwv li, 3528) - 6.9 mm², uas yog ntau dua 70% ntawm tag nrhotag nrho cheeb tsam ntawm lub nti.
  • Ntau cov neeg sib cuag rau cov cua sov ntxiv.

SMD-LEDs 2835 yog nyob rau hauv pab pawg ntawm cov cuab yeej ua haujlwm siab ua haujlwm siab ntawm lub zog nruab nrab thiab tsim los rau saum npoo ntawm lawv cov yam ntxwv, raws li kev faib tawm hauv Lavxias thiab thoob ntiaj teb.

Ua haujlwm voltage thiab ntsuas tam sim no

Ntawm cov yam ntxwv hluav taws xob, muaj ob lub ntsiab uas cuam tshuam rau kev xaiv lub zog:

  • Ua haujlwm voltage (voltage poob hla lub LED nws tus kheej) - feem ntau qhia nyob rau hauv lub ntaus ntawv Performance index thiab yog tus nqi nruab nrab ntawm qhov tsawg kawg nkaus thiab siab tshaj tus nqi tso cai.
  • Cov ntsuas tam sim no ntws los ntawm cov khoom lag luam, uas yog qhov tsim nyog rau kev ua haujlwm kom raug thiab ua kom ntseeg tau rau lwm yam tsis tau tshaj tawm los ntawm cov chaw tsim khoom.

Raws li cov yam ntxwv tam sim no-voltage, SMD 2835 LEDs tam sim no tsim:

  • nrog kev ua haujlwm voltage: 3, 6 thiab 9V;
  • nrog ntsuas tam sim no ntawm 60 txog 150mA.

Kev xaiv ntawm ib yam khoom yog nyob ntawm nws daim ntawv thov.

Note! Rau kev ua haujlwm ntev thiab tsis muaj teeb meem ntawm LED, tus tsav tsheb tsim nyog yuav tsum tau siv.

Lub teeb tso zis, kev ua haujlwm thiab lub zog

Cov no yog peb qhov tseem ceeb tshaj plaws thiab muaj kev cuam tshuam cov yam ntxwv ntawm 2835 LED. Rau cov khoom 2835, hauvnyob ntawm qhov kev hloov kho tshwj xeeb, nws tus nqi yog nyob rau hauv ntau yam ntawm 24-29 lm (rau ntau yam nrog kev ua haujlwm voltage ntawm 3 V thiab ntsuas tam sim no ntawm 60 mA) txog 130-140 lm (rau cov qauv tsim los ua haujlwm ntawm 6- 9V thiab ntsuas tam sim no 100-150 mA).

Qhov ua tau zoo ntawm cov cuab yeej yog qhov piv ntawm lub zog ntawm lub luminous flux rau lub zog nws siv. Series 2835 hais txog cov khoom siv ua haujlwm siab. Tus nqi ntawm qhov ntsuas no yog nyob rau hauv thaj tsam ntawm 120 txog 170 lm / W. Nws yog los ntawm qhov ntsuas no uas ib tus tuaj yeem sib piv cov teeb pom kev zoo uas siv ntau yam thev naus laus zis (incandescent, fluorescent, halogen thiab LED) nrog rau ib leeg.

Lub zog noj ntawm 2835 LEDs tam sim no yog: 0, 2, 0.5 lossis 1.0W.

Glow kub thiab dispersion kaum

Txawm hais tias tag nrho 2835 hom LEDs emit lub teeb dawb, xim kev nkag siab ntawm kev hloov pauv txawv txawv. Qhov ntsuas no yog hu ua qhov kub thiab txias (lossis xim kub) thiab qhia hauv degrees Kelvin. Raws li qhov ntsuas no, txhua yam khoom siv tau muab faib ua peb pawg tseem ceeb:

  • 2700-3500K - sov dawb (feem ntau reminiscent ntawm lub teeb los ntawm ib tug dog dig incandescent teeb);
  • 3500-5000K - nruab nrab dawb (lossis nruab hnub);
  • 5000-6500 K - txias dawb (siv tsuas yog siv rau kev tsim lub tsheb taub hau thiab tuav lub teeb nyem, nrog rau kev teeb pom kev zoo).

2835 cov khoom lag luam muaj nyob rau hauv tag nrho peb pawg xim kub.

Ib yam ntxivIb qho tseem ceeb yam ntxwv ntawm 2835 LED yog lub kaum sab xis. Tus nqi no qhia txog lub kaum sab xis ntawm lub teeb nthuav dav, nyob rau hauv uas qhov kev siv ntawm lub teeb flux yuav tsawg kawg yog ½ ntawm qhov ntawm lub axis ntawm cov siv lead ua. Rau LEDs ntawm no series, daim duab no yog 120⁰.

Qhov zoo thiab daim ntawv thov

2835 LEDs muaj ntau qhov txiaj ntsig tsis tuaj yeem:

  • kev txuag hluav taws xob zoo nrog lub zog qis;
  • me me;
  • xaiv ntau yam kev hloov kho;
  • lub kaum sab xis loj;
  • dav ua haujlwm kub ntau (ntawm -40⁰С txog +105⁰С);
  • qis pulsation ntawm glow;
  • ua haujlwm siab rau kev ntxhov siab thiab kev co;
  • ntev kev pab cuam lub neej.

Tag nrho cov txiaj ntsig no thiab kev ua haujlwm siab tau txiav txim siab siv dav ntawm LEDs ntawm cov koob no hauv ntau yam khoom siv teeb pom kev zoo: teeb, lub teeb vaj huam sib luag ntawm ntau qhov ntau thiab tsawg, LED raj, thiab lwm yam.

5730 vs 2835 LED kev sib piv

Keeb kwm, 5730 qhov loj LEDs tau tshwm sim hauv khw ntau dua li 2835. Yog li ntawd, thaum pib lawv tau siv dav heev hauv kev tsim cov roj teeb txuag hluav taws xob. Tam sim no 2835 LEDs tab tom hloov 5730 hom ntawv. Rau kev sib piv, cia peb coj cov khoom siv los ntawm ib tus neeg paub zoo hauv peb lub teb chaws thiab cov chaw tsim khoom hauv Suav teb zoo Honglitronic. Muab pivpab kiag li lawm ntawm ntau yam qauv ntawm tib lub zog thiab luminous ntau yam, peb tuaj mus rau qhov xaus hais tias cov yam ntxwv kev (ob leeg ua hauj lwm thiab siab tshaj plaws tso cai) yog yuav luag zoo tib yam.

Qhov txawv tsuas yog nyob rau hauv cov qauv tsim: lub 5730 lub cev ho ntau tshaj 2835 nyob rau hauv ob qho tib si cheeb tsam thiab thickness.
