Iwo akajairika voltages e LED mitsetse ndeye 12VDC uye 24VDC, uye mitengo yavo yakafanana. Paunenge wagadzirira kutenga LED mitsetse, unogona kunge uine mibvunzo, ndeupi musiyano uripo pakati pe12VDC mitsetse uye 24VDC mitsetse? Ndeipi yandinofanira kusarudza?
LEDYi inowanzopa zvose 12VDC uye 24VDC Zvipenga zve LED. Mumamiriro ezvinhu akajairwa, mutsauko uripo pakati pe12VDC LED strip uye 24VDC LED strip haina kunyanyokurisa, chero ukasarudza iyo chaiyo magetsi.
Kana iwe uchida kureba kupfupi, tinokurudzira kusarudza 12VDC LED strip. Kune iyo tambo ye LED ine huwandu hwakafanana hwe LED, kureba kwakachekwa kweiyo 12VDC LED strip hafu yeiyo ye24V LED strip. Izvi zvinokupa iwe kuwedzera kuchinjika kutema iyo LED strip kusvika pakureba kwaunoda.
Kana iwe uchida mutsara wakareba uye unopenya zvakanyanya, tinokurudzira kusarudza 24VDC LED mitsetse.
Kana iwe uchida kuziva zvakawanda nezve tekinoroji maficha, verenga pazasi kuti uwane misiyano yakawanda:
12VDC LED tambo ine ipfupi kucheka kureba
Mazhinji ega ega machipisi e LED anomhanya pa 3VDC simba zvisinei nekuti akaiswa pa 12V tambo kana 24V tambo. Muchokwadi, iyo yakafanana LED chip inoshanda pane 12V strip inogona zvakare kuisirwa pane 24V strip. Chii chinoita mutsauko ndechekuti strip circuitry yakagadzirwa.
LED Strips ine waya mumapoka e LEDs. Saizi ye
boka rinoenderana nemagetsi emutsetse. Mutsetse we12V une maLED matatu, uye 3V strip ine 24 LEDs kana 6 LEDs, kunyangwe anosvika masere maLED. Mitsetse yakachekwa inowanikwa pakati pemapoka. Naizvozvo, idiki rimwe nerimwe boka re LEDs, iyo inoswedera pamwe chete mitsetse yakachekwa inogona kuva.
Semuenzaniso, ona madhayagiramu e12V uye 24V mitsetse pazasi:
Iyo yakaderera voltage 12VDC strip ine mitsetse yepedyo yakachekwa inogona kuve yakanaka kana kuisirwa kwako kune makona mazhinji ane hurefu hupfupi. Izvi zvinogona kubatsira kuderedza "rima" nzvimbo pamakona.
Kuti uwane mukana weiyo Long Run ye24VDC LED tambo uye ipfupi yekucheka kureba kwe5VDC LED strip, isu takagadzira. Mini Kucheka LED Strip, 1 LED pakucheka pa24VDC.
12V LED strip ine huwandu hwakakura hwemashandisirwo mamiriro
Kune rimwe divi, 12 VDC ndeye yakajairika voltage, saka LED mitsetse inoenderana inogona kubvisa kudiwa kwekuwedzera magetsi. Semuenzaniso, kana iwe uchiisa mwenje mumotokari, 12 VDC LED strip mwenje inogona kazhinji yakabatana zvakananga kune iripo magetsi system. Kunyange paine zvakasarudzika pane izvi, uye zvakakosha kuti utarise yako iripo system usati watenga, 12V LED mitsetse inogona kupa yakanyanya nyore yekuisa mhinduro muzviitiko zvakawanda.
24V LED tambo, yakareba mutsara kumhanya
Iyo yakakwira voltage strip inowanzo kwanisa kuita nguva refu isina kutambura kubva kumhedzisiro yekudonha kwevoltage.
Chii chinonzi voltage drop?
Kudonha kwevoltage kunoita kuti mitsetse ye LED irasikirwe nekusimba pavanenge vakareba. Ma LED pakutanga kwetambo (padyo nemagetsi emagetsi) achapenya zvakajeka. Kusiyana neizvi, ma LED ari kumagumo emutsetse achave nechimiro chakasviba.
Sei kudonha kwevoltage kuchiitika?
Chero hurefu hwetambo hune humwe huwandu hwekudzivisa magetsi. Iyo yakareba waya, inowedzera kuramba. Kuramba kwemagetsi kunokonzera kudonha kwemagetsi, uye kudonha kwemagetsi kunoita kuti maLED ako adzike.
Naizvozvo, ma LED pamagumo emutsetse anogara achiwana mashoma voltage pane iwo ekutanga. Kana iwe ukaita tambo yakareba zvakakwana, kudonha kwevoltage kunove kwakakosha zvakakwana kukonzera mutsauko unooneka mukupenya.
Yakakwira voltage inoderedza sei mhedzisiro yekudonha kwevoltage?
Kutanga, iwe unofanirwa kunzwisisa kuti ese maficha ari pa LED strip akabatana sei.
Mazhinji ega ega machipi e LED anomhanya pa 3V DC simba zvisinei nekuti akaiswa pa 12V tambo kana 24V tambo. Muchokwadi, iyo yakafanana LED chip inoshanda pane 12V strip inogona zvakare kuisirwa pane 24V strip. Chii chinoita mutsauko ndechekuti strip circuitry yakagadzirwa.
LED machipisi akaiswa waya munhevedzano mumapoka. Boka rega rega rine mamwe machipisi e LED uye anopikisa. Kudonha kwemagetsi kwese kweboka kunofanirwa kuenzana nemagetsi ese emutsetse (ona madhaigiramu pazasi).
Zvadaro, boka rimwe nerimwe rinoiswa waya mukuenzanisa uye rinorongwa pamwe chete nehurefu hwetambo.
Parizvino, cherechedza (madhayagiramu ari pamusoro) kuti saizi yeboka pane 24V strip ndeye 7 LEDs zvichienzaniswa ne3 chete maLED e12V. Ini ndichatsanangura kuti sei izvi zvakakosha pazasi.
Waya imwe neimwe ine mwero wakati wekupokana nemagetsi ari kusundidzirwa kuburikidza nawo. Iyo yakareba waya inowana, iyo yakakura kuramba (uye kudonha kwemagetsi) kunowedzera. Pakupedzisira, inokura zvakakwana kuti iite kupenya kwe LED. Pazasi pane muenzaniso wekuti zvingaitike sei pane 12V strip.
Ziva mudhayagiramu iri pamusoro apa kuti voltage pa LEDs yadzika kubva pa3.0V kuenda pa2.75V.
Kana isu tichichinjira ku24V, zvinhu zviviri zvinoitika izvo zvinoderedza kudonha kwemagetsi.
Kana simba racho rakapetwa kaviri (12V kusvika 24V), ikozvino inoparadzaniswa nepakati (Ohm mutemo P = U * I). Izvo zvinoita kuti kudonha kwevoltage kubva kune refu waya kuderedzwa nehafu zvakare. Saka pachinzvimbo chekudonha kwe1V, inova 0.5V kudonha.
Mhedzisiro yekudonha kwe0.5V inopatsanurwa pakati pezvikamu zvisere zvasara zvedunhu (zvichienzaniswa ne4 pa12V).
Ziva pano kuti voltage pa LEDs yakangodonha kusvika ku2.9375V kana ichienzaniswa ne2.75V ine 12V strip.
Kana iwe uine application inoda mitsetse yakareba, ingave iri zano rakanaka kushandisa 24V mitsetse. Asi, kunyange 24V mitsetse ine muganhu. Iwe unogona kushandisa mamwe maitiro ekumisa ma LED ako kubva pakupera. Somuenzaniso, kushandisa yedu Super Long Constant Current LED Strips.
24V LED strip inogona kuve yakanyanya kushanda zvakanaka
Higher voltage inogona kushanda zvakanyanya.
Chero nguva paine voltage pane resistor, zvinoreva kuti simba riri kushandurwa kuve kupisa panzvimbo yechiedza. Naizvozvo, iwo anopikisa ari mudhayagiramu ari pamusoro anodiwa, asi iwo zvakare sosi yekurasa simba.
| Total voltage of strip | Voltage pane resistor | % Simba "rakaparara" pane zvinopikisa |
| 5V (1 LED Paboka) | 2V | 40% |
| 12V (3 LEDs paBoka) | 3V | 25% |
| 24V (7 LEDs paBoka) | 3V | 12.5% |
Zviri nyore kuona kuti yakakwirira voltage mitsetse inotambura kubva kushoma kupera simba. Ma LED anoshandisa simba shoma rakadaro zvekuti izvi hazviwedzeri kusvika padiki pakuisa zvidiki. Asi, mutsauko mukushandiswa kwesimba unogona kuve wakakosha kune yese kamuri kana kushambadzira kwekutengesa.
Isu takagadzira yakakwirira-inoshanda LED mitsetse, 8 LEDs pakucheka, kusvika ku190LM/w.
Iyi ndiyo nheyo yakafanana neyepamusoro-voltage simba rekufambisa. Iyo yakakwirira yemagetsi, iyo idiki ikozvino. Zvinoenderana nemutemo waOhm, iyo voltage inodonha VDonhedza=I * R, simba remagetsi rinoshandurwa kuita kupisa P = U * I = (I * R) * I = I 2 *R.
24V LED strip inoda shoma conductor geji
Simba remagetsi rinosarudzwa ne equation P = V * I. Kuchengetedza simba rimwechete (P), kana voltage (V) ichikwira, ikozvino (I) inofanira kuburuka nehuwandu hwehuwandu.
Kana tikachengeta 48W sechinangwa chedu chekubuda semuenzaniso wekongiri, 12V system inoda 4 Amps (12V x 4A = 48W), nepo 24V system inongoda 2 Amps (24V x 2A = 48W).
Zvichitaurwa zviri nyore, iyo 24V LED sisitimu inodhonza hafu yehuwandu hwazvino se 12V LED sisitimu yekuwana iyo yakafanana simba nhanho.
Nei izvi zvichikosha?
Yese yazvino, kwete voltage, inosarudza ukobvu uye hupamhi hwemhangura conductor inodiwa kuendesa simba zvakachengeteka.
Kana huwandu hwakawandisa hwemazuva ano hukamanikidzwa kuburikidza nediki kana nhete yemhangura conductor, kuramba mukati me conductor kunova kwakakosha uye kunobatsira mukudonha kwevoltage uye kugadzirwa kwekupisa. Muzviitiko zvakanyanyisa, izvi zvinogona kutotungamirira kumoto wemagetsi.
Zvese zvimwe zvakaenzana, 24V LED system inogona kubva nehafu yemagetsi conductor zvinodiwa. Unogona kushandisa yedu voltage drop calculator kuve nechokwadi kuti uchiri kushandisa akakwana conductor geji kune ako LED strip mapurojekiti.
Madiki emagetsi emagetsi e24V LED strip
Kunge saizi yeconductor, saizi yemagetsi inotemerwawo zvakanyanya neazvino kwete voltage. Chikamu cheizvi chinopesvedzerwawo nehukama hwefizikisi pakati pemagetsi azvino uye saizi ye conductor, sezvo yakawanda yemagetsi emagetsi emukati wiring inosanganisira copper wiring.
Saizi yemagetsi inogona kuve yakakosha kana uchishanda nemapurojekiti akadai semarambi e LED muzasi kwekabati yekumisikidza uko panogona kunge paine zvimhingamipinyi.
mhedziso
Ini ndinotenda kuti mushure mekuverenga chinyorwa ichi, iwe neni tasvika pamhedziso imwechete yekuti zvakanakira 24VDC LED mitsetse yakakura kupfuura 12VDC LED mitsetse. Kana zvichibvira, kunyanya mumapurojekiti makuru emwenje, ndapota shandisa 24VDC LED mitsetse.
LEDYi inogadzira yepamusoro-soro LED mitsetse uye LED neon flex. Zvese zvigadzirwa zvedu zvinopfuura nepamusoro-tech marabhoritari kuve nechokwadi chemhando yepamusoro.
