Ngati mukufuna kudziwa zambiri zaukadaulo, werengani pansipa kuti mumve zambiri:

12VDC Mzere wa LED wokhala ndi utali wamfupi wodulidwa

Ma tchipisi ambiri a LED amayendera mphamvu ya 3VDC mosasamala kanthu kuti ayikidwa pamzere wa 12V kapena 24V. M'malo mwake, chip chomwecho cha LED chomwe chimagwira ntchito pamzere wa 12V chitha kuyikidwanso pamzere wa 24V. Chomwe chimapangitsa kusiyana ndi momwe ma strip circuitry amapangidwira.

Mizere ya LED imakhala ndi mawaya m'magulu a ma LED. Kukula kwa
gulu zimadalira voteji wa Mzere. Mzere wa 12V uli ndi ma LED atatu, ndipo mzere wa 3V uli ndi ma LED 24 kapena ma LED 6, ngakhale ma LED 7. Mizere yodulidwa ili pakati pa magulu. Choncho, ang'onoang'ono gulu lirilonse la ma LED, kuyandikana kwa mizere yodulidwa kungakhale.

Mwachitsanzo, onani zithunzi za 12V ndi 24V mizere pansipa:

Mzere wocheperako wa 12VDC wokhala ndi mizere yoyandikira kwambiri ungakhale wabwino ngati kuyika kwanu kuli ndi ngodya zambiri zazitali zazifupi. Izi zingathandize kuchepetsa "dark" zone pamakona.

Kuti tipeze mwayi wa Long Run wa 24VDC LED Mzere ndi zazifupi kudula kutalika kwa 5VDC LED Mzere, tapanga Mini Kudula Mzere wa LED, 1 LED pa kudula pa 24VDC.

Mzere wa 12V LED uli ndi mawonekedwe osiyanasiyana ogwiritsira ntchito

Kumbali ina, 12 VDC ndi voteji wamba, kotero kuti LED mizere yogwirizana akhoza kuthetsa kufunika kwa magetsi owonjezera. Mwachitsanzo, ngati mukuyika magetsi m'galimoto, nyali ya 12 VDC ya LED imatha kulumikizidwa mwachindunji kumagetsi omwe alipo. Ngakhale pali zosiyana ndi izi, ndipo ndikofunikira kuyang'ana makina anu omwe alipo musanagule, mizere ya 12V LED imatha kukupatsani njira yabwino yokhazikitsira nthawi zambiri.

24V Mzere wa LED, kuthamanga kwa mzere wautali

Mzere wokwera kwambiri wamagetsi nthawi zambiri utha kukhala ndi nthawi yayitali popanda kuvutika ndi kutsika kwamagetsi.

Kodi voltage drop ndi chiyani?

Kutsika kwa magetsi kumapangitsa kuti mizere ya LED iwonongeke ikakula. Ma LED kumayambiriro kwa mzere (pafupi ndi magetsi) adzawala kwambiri. Mosiyana ndi izi, ma LED kumapeto kwa mzerewo adzakhala ndi mawonekedwe amdima.

Chifukwa chiyani kutsika kwa voltage kumachitika?

Utali uliwonse wa waya uli ndi kuchuluka kwa mphamvu zamagetsi. Kutalika kwa waya, kumatsutsana kwambiri. Kukana kwa magetsi kumayambitsa kutsika kwa magetsi, ndipo kutsika kwa magetsi kumapangitsa kuti ma LED anu azichepa.
Chifukwa chake, ma LED kumapeto kwa mzere nthawi zonse amakhala ndi magetsi ochepa kuposa omwe ali pachiyambi. Mukapanga mzerewo kutalika kokwanira, kutsika kwamagetsi kumakhala kofunikira kwambiri kuti kupangitse kusiyana kowoneka bwino.

Kodi ma voltage okwera amachepetsa bwanji kutsika kwamagetsi?

Choyamba, muyenera kumvetsetsa momwe zida zonse zomwe zili pamtundu wa LED zimalumikizidwa.

Tchipisi zambiri za LED zimayenda pa mphamvu ya 3V DC mosasamala kanthu kuti zayikidwa pamzere wa 12V kapena 24V. M'malo mwake, chip chomwecho cha LED chomwe chimagwira ntchito pamzere wa 12V chitha kuyikidwanso pamzere wa 24V. Chomwe chimapangitsa kusiyana ndi momwe ma strip circuitry amapangidwira.

Tchipisi za LED zimalumikizidwa ndi mawaya angapo m'magulu. Gulu lirilonse liri ndi tchipisi ta LED ndi chopinga. Kutsika kwamagetsi pagululo kuyenera kukhala kofanana ndi voteji yonse ya mzerewo (onani zithunzi pansipa).

Kenako, gulu lililonse limalumikizidwa ndi mawaya ofanana ndikulilinganiza molingana ndi kutalika kwa mzerewo.

Pakadali pano, zindikirani (pazithunzi pamwambapa) kuti kukula kwa gulu pamzere wa 24V ndi ma LED 7 poyerekeza ndi ma LED atatu okha a 3V. Ndifotokoza chifukwa chake izi ndizofunikira pansipa.

Waya uliwonse uli ndi kuchuluka kwake kokana magetsi akukankhidwa kudzera pamenepo. Pamene wayayo amatalika, kukana kwakukulu (ndi kutsika kwa magetsi) kumawonjezeka. Pambuyo pake, imakula mokwanira kuti ikhudze kuwala kwa LED. Pansipa pali chitsanzo cha momwe zingachitikire pamzere wa 12V.

Zindikirani m'chithunzi pamwambapa kuti magetsi odutsa ma LED atsika kuchoka pa 3.0V kufika pa 2.75V.

Tikasintha ku 24V, zinthu ziwiri zimachitika zomwe zimachepetsa kutsika kwamagetsi.

Mphamvu yamagetsi ikachulukitsidwa (12V mpaka 24V), yapano imachepetsedwa ndi theka (lamulo la Ohm P=U * I). Izi zimapangitsa kutsika kwa magetsi kuchokera ku waya wautali kuchepetsedwa ndi theka. Chifukwa chake m'malo mwa dontho la 1V, limakhala dontho la 0.5V.

Zotsatira za dontho la 0.5V zimagawanika pakati pa zigawo zisanu ndi zitatu zotsalira za dera (poyerekeza ndi 4 pa 12V).

Zindikirani apa kuti magetsi odutsa ma LED adatsikira ku 2.9375V poyerekeza ndi 2.75V yokhala ndi mzere wa 12V.
Ngati muli ndi pulogalamu yomwe imafunikira mizere yayitali, lingakhale lingaliro labwino kugwiritsa ntchito mizere ya 24V. Koma, ngakhale mizere ya 24V ili ndi malire. Mungafunike kugwiritsa ntchito njira zina kuti muyimitse ma LED anu kuti asathere kumapeto. Mwachitsanzo, ntchito wathu Ma Super Long Constant Current Current Mizere ya LED.

24V Mzere wa LED ukhoza kukhala wopambana kwambiri

Mphamvu yamagetsi yapamwamba imatha kukhala yothandiza kwambiri.

Nthawi iliyonse pali voteji pa resistor, zikutanthauza kuti mphamvu ikusandulika kutentha m'malo mwa kuwala. Chifukwa chake, zopinga zomwe zili pamwambazi ndizofunikira, koma ndizomwe zimawononga mphamvu.

Ndikosavuta kuwona kuti mizere yokwera kwambiri yamagetsi imakhala ndi mphamvu zochepa zomwe zimawonongeka. Ma LED amagwiritsa ntchito mphamvu yaying'ono kwambiri kotero kuti izi sizimawonjezera zochulukirapo pakuyika kwazing'ono. Koma, kusiyana kwa kugwiritsa ntchito mphamvu kumatha kukhala kofunikira pachipinda chonse kapena mabizinesi.

Tapanga mizere ya LED yamphamvu kwambiri, Ma LED 8 pa kudula, mpaka 190LM/w.

Iyi ndi mfundo yofanana ndi kufala kwamphamvu kwamagetsi. Kukwera kwamagetsi, kumakhala kochepa kwambiri. Malingana ndi lamulo la Ohm, kutsika kwa magetsi V_kusiya=I * R, mphamvu yamagetsi yosinthidwa kukhala kutentha P=U * I = (I * R) * I = I ² *R.

Mzere wa 24V wa LED umafunikira kondakitala wocheperako

Mphamvu yamagetsi imatsimikiziridwa ndi equation P = V * I. Kuti mukhalebe ndi mphamvu yofanana (P), ngati voteji (V) ikukwera, panopa (I) iyenera kutsika ndi kuchuluka kwake.

Ngati tisunga 48W monga chotsatira chathu monga chitsanzo cha konkire, dongosolo la 12V lidzafuna 4 Amps (12V x 4A = 48W), pamene dongosolo la 24V lidzangofuna 2 Amps (24V x 2A = 48W).

Mwachidule, dongosolo la 24V LED lidzakoka theka la kuchuluka kwamakono monga 12V LED dongosolo kuti likwaniritse mphamvu yomweyo.

Nchifukwa chiyani izi ziri zofunika?

Total panopa, osati voteji, zimatsimikizira makulidwe ndi m'lifupi ma conductor zamkuwa zofunika kusamutsa mphamvu bwinobwino.

Ngati kuchulukitsitsa kwamagetsi kumakakamizika kudzera pa kondakitala yamkuwa yaying'ono kapena yopapatiza, kukana mkati mwa kondakita kumakhala kofunika kwambiri ndipo kumathandizira kutsika kwamagetsi ndi kutulutsa kutentha. Pazovuta kwambiri, izi zimatha kuyambitsa moto wamagetsi.

Zina zonse zofanana, dongosolo la 24V LED limatha kuthawa ndi theka la zofunikira za conductor wamagetsi. Mutha kugwiritsa ntchito calculator yotsika mtengo onetsetsani kuti mukugwiritsabe ntchito zoyezera zowongolera zokwanira pama projekiti anu amtundu wa LED.

Magetsi ang'onoang'ono a 24V LED strip

Mofanana ndi kukula kwa kondakitala, kukula kwa magetsi kumatsimikiziridwa makamaka ndi panopa osati magetsi. Zina mwa izi zimakhudzidwanso ndi ubale wa fiziki pakati pa zosowa zamagetsi zamagetsi ndi kukula kwa kondakitala, chifukwa mawaya amkati amagetsi amakhala ndi mawaya amkuwa.

Kukula kwa magetsi kumatha kukhala kofunikira mukamagwira ntchito ndi mapulojekiti monga nyali za mizere ya LED mkati mwa makhazikitsidwe a kabati pomwe pangakhale zopinga.
