Na kowa voltages na LED tube ne 12VDC da 24VDC, kuma farashin su iri daya ne. Lokacin da kuke shirye don siyan filayen LED, kuna iya samun tambayoyi, menene bambanci tsakanin tsiri 12VDC da 24VDC tube? Wanne zan zaba?
LEDYi gabaɗaya yana ba da duka 12VDC da 24VDC LED tsiri. A karkashin yanayi na al'ada, bambancin dake tsakanin 12VDC LED tsiri da 24VDC LED tsiri bai yi girma ba, muddin ka zaɓi samar da wutar lantarki daidai.
Idan kana buƙatar guntun tsayin yanke, muna ba da shawarar zabar tsiri 12VDC LED. Don tsiri na LED tare da adadin LED iri ɗaya, yanke tsayin tsiri na LED na 12VDC shine rabin na 24V LED tsiri. Wannan yana ba ku ƙarin sassauci don yanke igiyar LED zuwa tsayin da kuke so.
Idan kuna buƙatar gudu mai tsayi mai tsayi da ingantaccen haske, muna ba da shawarar zaɓar filaye na LED 24VDC.
Idan kuna sha'awar ƙarin koyo game da abubuwan fasaha, karanta ƙasa don ƙarin bambance-bambance:
12VDC LED tsiri tare da guntun yanke tsawon
Yawancin kwakwalwan kwamfuta na LED guda ɗaya suna gudana akan ƙarfin 3VDC ba tare da la'akari da ko an ɗora su akan tsiri 12V ko tsiri 24V ba. A zahiri, guntu na LED guda ɗaya wanda ke aiki akan tsiri 12V shima ana iya hawa akan tsiri 24V. Abin da ya bambanta shi ne yadda aka ƙera ƙwanƙwasa tsiri.
LED Strips suna waya a cikin rukunoni na LEDs. Girman girman
rukuni ya dogara da ƙarfin lantarki na tsiri. Tushen 12V yana da LEDs 3, kuma tsiri 24V yana da LEDs 6 ko LEDs 7, har zuwa LEDs 8. Layukan da aka yanke suna tsakanin ƙungiyoyi. Saboda haka, ƙarami kowane rukuni na LEDs, mafi kusa tare da yanke layin zai iya zama.
Misali, duba zane-zane na 12V da 24V a ƙasa:
Ƙananan ƙarfin lantarki 12VDC tsiri tare da layukan yanke kusa zai iya zama mai kyau idan shigarwar ku yana da kusurwoyi da yawa tare da gajeren tsayi. Wannan zai iya taimakawa wajen rage girman yankin "duhu" a sasanninta.
Don samun fa'idar Dogon Run na 24VDC LED tsiri da guntun yankan tsayi na 5VDC LED tsiri, mun haɓaka. Mini Yankan LED Strip, 1 LED a kowane yanke a 24VDC.
12V LED tsiri yana da fadi da kewayon aikace-aikace yanayin
A gefe guda, 12 VDC wutar lantarki ce ta gama gari, don haka daidaituwar tsiri LED na iya kawar da buƙatar ƙarin kayan wuta. Misali, idan kuna shigar da fitulu a cikin abin hawa, ana iya haɗa hasken fitilun LED 12 VDC sau da yawa zuwa tsarin wutar lantarki da ake da shi. Duk da yake akwai wasu keɓancewa ga wannan, kuma yana da mahimmanci don bincika tsarin da kuke da shi kafin siyan siye, 12V LED tube na iya ba da mafita mafi dacewa da shigarwa a yawancin lokuta.
24V LED tsiri, dogon layin gudu
Babban tsiri mai ƙarfin lantarki gabaɗaya zai iya samun tsayin gudu ba tare da ya sha wahala daga faɗuwar wutar lantarki ba.
Menene raguwar wutar lantarki?
Faɗuwar wutar lantarki yana haifar da tube LED su rasa ƙarfinsu yayin da suke tsayi. LEDs a farkon tsiri (mafi kusa da wutar lantarki) za su haskaka haske. Sabanin haka, LEDs a ƙarshen tsiri za su sami siffar dimmed.
Me yasa raguwar wutar lantarki ke faruwa?
Duk tsawon waya yana da ƙayyadaddun juriya na lantarki. Da tsayi da waya, da ƙarin juriya. Juriyar wutar lantarki yana haifar da raguwar wutar lantarki, kuma raguwar wutar lantarki yana sa LEDs ɗin ku su yi rauni.
Don haka, LEDs a ƙarshen tsiri koyaushe za su sami ƙarancin ƙarfin lantarki fiye da waɗanda suke a farkon. Idan kun yi tsiri ya yi tsayi sosai, raguwar ƙarfin lantarki zai zama mahimmanci isa ya haifar da bambancin haske a bayyane.
Ta yaya mafi girman ƙarfin lantarki ke rage tasirin faɗuwar wutar lantarki?
Da farko, dole ne ku fahimci yadda ake haɗa duk abubuwan da ke kan tsiri na LED.
Yawancin kwakwalwan kwamfuta na LED guda ɗaya suna gudana akan ikon 3V DC ko da kuwa an ɗora su akan tsiri 12V ko tsiri 24V. A zahiri, guntu na LED guda ɗaya wanda ke aiki akan tsiri 12V shima ana iya saka shi akan tsiri 24V. Abin da ya bambanta shi ne yadda aka ƙera ƙwanƙwasa tsiri.
LED kwakwalwan kwamfuta ana waya a jeri zuwa kungiyoyi. Kowane rukuni ya ƙunshi wasu guntu na LED da resistor. Jimillar raguwar wutar lantarki a cikin ƙungiyar dole ne ta zama daidai da jimlar ƙarfin wutar lantarki na tsiri (duba zanen da ke ƙasa).
Sa'an nan kuma, kowace ƙungiya ana yin waya a layi daya kuma an tsara su tare da tsayin tsiri.
A yanzu, lura (a sama zane-zane) cewa girman rukuni akan tsiri 24V shine LEDs 7 idan aka kwatanta da LEDs 3 kawai don 12V. Zan bayyana dalilin da yasa wannan yake da mahimmanci a ƙasa.
Kowace waya tana da ƙayyadaddun juriya ga wutar lantarki da ake turawa ta cikinta. Yayin da waya ta yi tsayi, girman juriya (da raguwar ƙarfin lantarki) ke samun. A ƙarshe, yana samun babban isa don tasiri hasken LED. A ƙasa akwai misalin yadda zai iya faruwa akan tsiri 12V.
Lura a cikin zanen da ke sama cewa ƙarfin lantarki a kan LEDs ya ragu daga 3.0V zuwa 2.75V.
Lokacin da muka canza zuwa 24V, abubuwa biyu suna faruwa waɗanda ke rage raguwar ƙarfin lantarki.
Lokacin da ƙarfin lantarki ya ninka sau biyu (12V zuwa 24V), na yanzu yana raguwa (Dokar Ohm P=U * I). Hakan ya sa raguwar wutar lantarki daga dogon waya ta ragu da rabi kuma. Don haka maimakon digon 1V, ya zama digo 0.5V.
Tasirin digo na 0.5V yana raba tsakanin sauran abubuwan kewayawa guda takwas (idan aka kwatanta da 4 akan 12V).
Lura anan cewa wutar lantarki a fadin LEDs ya ragu zuwa 2.9375V idan aka kwatanta da 2.75V tare da tsiri 12V.
Idan kana da aikace-aikacen da ke buƙatar dogon gudu na tsiri, yana iya zama kyakkyawan ra'ayi don amfani da tube 24V. Amma, ko da 24V tube yana da iyaka. Kuna iya amfani da wasu dabaru don hana LEDs ɗinku daga dusashewa a ƙarshe. Misali, amfani da mu Super Long Constant LED Strips na yanzu.
24V LED tsiri iya zama mafi girma yadda ya dace
Babban ƙarfin lantarki na iya zama mafi inganci.
Duk lokacin da aka sami ƙarfin lantarki a kan resistor, yana nufin makamashi yana canzawa zuwa zafi maimakon haske. Saboda haka, resistors a cikin zanen da ke sama sun zama dole, amma kuma sune tushen kuzarin da ba a so.
| Jimlar ƙarfin lantarki na tsiri | Voltage a fadin resistor | % Ƙarfin “ɓatacce” akan resistors |
| 5V (1 LED kowace rukuni) | 2V | 40% |
| 12V (LEDs 3 a kowace rukuni) | 3V | 25% |
| 24V (LEDs 7 a kowace rukuni) | 3V | 12.5% |
Yana da sauƙi a ga cewa mafi girman igiyoyin wutar lantarki suna fama da ƙarancin ɓata kuzari. LEDs suna amfani da irin wannan ƙaramin adadin kuzari wanda wannan baya ƙarawa da yawa don ƙananan kayan aiki. Amma, bambance-bambancen amfani da wutar lantarki na iya zama mahimmanci ga ɗaukacin ɗakin ko shigarwar kasuwanci.
Mun ci gaba high-inganci LED tube, 8 LEDs a kowane yanke, har zuwa 190LM/w.
Wannan ƙa'ida ɗaya ce da watsa wutar lantarki mai ƙarfi. Mafi girman ƙarfin lantarki, ƙarami na halin yanzu. Bisa ga dokar Ohm, ƙarfin lantarki sauke Vsauke= I * R, wutar lantarki ta canza zuwa zafi P = U * I = (I * R) * I = I 2 *R.
24V LED tsiri yana buƙatar ƙarancin ma'aunin madugu
Ana ƙayyade ƙarfin lantarki ta hanyar ƙididdiga P = V * I. Don kula da wannan ƙarfin (P), idan ƙarfin lantarki (V) ya tashi, halin yanzu (I) dole ne ya sauko da adadin daidai.
Idan muka ci gaba da 48W a matsayin fitowar da muka yi niyya azaman misali mai mahimmanci, tsarin 12V zai buƙaci 4 Amps (12V x 4A = 48W), yayin da tsarin 24V zai buƙaci 2 Amps kawai (24V x 2A = 48W).
A taƙaice, tsarin LED na 24V zai zana rabin adadin na yanzu azaman tsarin LED na 12V don cimma matakin ƙarfin iri ɗaya.
Me ya sa wannan yake da muhimmanci?
Jimlar halin yanzu, maimakon ƙarfin lantarki, yana ƙayyade kauri da faɗin madugu na jan ƙarfe da ake buƙata don canja wurin wuta lafiya.
Idan an tilasta yawan adadin halin yanzu ta ƙarami ko kunkuntar madubin jan ƙarfe, juriya a cikin madubin zai zama mahimmanci kuma yana ba da gudummawa ga raguwar ƙarfin lantarki da samar da zafi. A cikin matsanancin yanayi, wannan na iya haifar da gobarar lantarki.
Duk dai daidai, tsarin LED na 24V na iya tserewa tare da rabin buƙatun jagoran lantarki. Kuna iya amfani da Ƙididdigar ƙarfin lantarki don tabbatar da cewa har yanzu kuna amfani da isassun ma'aunin madugu don ayyukan tsiri na LED ɗinku.
Ƙananan kayan wuta don 24V LED tsiri
Kamar girman madugu, girman wutar lantarki kuma ana ƙaddara ta farko ta halin yanzu maimakon ƙarfin lantarki. Wani sashe na wannan yana da tasiri da alaƙar kimiyyar lissafi tsakanin wutar lantarki da buƙatun girman madugu, saboda yawancin na'urar samar da wutar lantarki ta ciki ta ƙunshi wayoyi na tagulla.
Girman samar da wutar lantarki na iya zama mahimmanci yayin aiki tare da ayyuka kamar fitilun fitilun LED a ƙarƙashin kayan aikin majalisar inda za'a iya samun iyakokin sarari.
