Ukufunda iskimu sangaphakathi semigca ye-LED kuya kukuthatha ujule kulwakhiwo lwesi silungiso sibhetyebhetye. Ke, ukuba ufuna ukwazi umtya we-LED ukusuka kwingcambu yawo, eli nqaku lelakho!
I-PCB yokukhanya komcu we-LED inika umzobo iteyiphu okanye isakhiwo esifana nentambo. Ngokusisiseko ngowona mzimba uphambili wolwakhiwo lomtya we-LED apho kuhlala khona amanye amacandelo amancinci. Ezi ziquka chips LED, resistors, capacitors, njl Kwaye onke la magama zidityanisiwe ukwenza ukukhanya strip LED. Nangona kunjalo, ukulinganiswa kombane kubalulekile ukuqinisekisa ukusebenza kakuhle kokukhanya.
Kweli nqaku, ndigubungele lonke ulwazi olusisiseko malunga neskimu sangaphakathi sezibane ze-LED kunye neemfuno zabo zombane. Ukuba awuqhelananga nezibane zestrip ze-LED kwaye ufuna ukwazi ngazo, esi sikhokelo siya kuba yeyona ndlela ilungileyo ukuqala ngayo-
I-Schematic yangaphakathi ye-LED Strip Lights
Isicwangciso sangaphakathi semicu ye-LED ebhityileyo kakhulu kwaye ebhetyebhetye iya kukumangalisa; zenziwe ngamacandelo amancinci amaninzi. Amalungu asisiseko angaphakathi kwiintambo ze-LED zezi zilandelayo-
- LED Bead
I-LED bead lelona candelo liphambili lomgca we-LED okhupha ukukhanya. Zenziwe ngamasuntswana e-semiconductor akhanyayo xa umbane udlula kuwo. Uninzi lwamaso amancinci e-LED acwangciswe ngaphakathi kwemichilo ye-LED. La maso anokuba nobukhulu obahlukeneyo. Ukukhanya kwezibane ze-LED kuxhomekeke kwinani, ubungakanani, kunye nokumila kwala maso. Ukwazi ngakumbi, jonga oku- Amanani kunye nee-LED: Ithetha ukuthini i-2835, i-3528, kunye ne-5050?
- IBhodi yeesekethe
Zonke izinto zemichilo ye-LED zicwangciswe kwibhodi yesekethe eprintiweyo, edla ngokubizwa ngokuba yiPCB. Ezi bhodi ziguquguquka kakhulu, zikuvumela ukuba ulolonge izibane zestrip njengoko kufuneka. Eyona nyaniso inomdla malunga ne-PCB kukuba banqumle amanqaku kuwo wonke umzimba. Ungayisika ngokulandela ukumakisha usebenzisa isikere. Oku kukunceda ukuba wenze ubungakanani bemigca ngokweemfuno zofakelo. Khangela Ngaba unokuSika izibane ze-LED Strip kunye nendlela yokuQhagamshela: Isikhokelo esipheleleyo ukufunda indlela yokusika imicu ye-LED.
- Isixhasi
I-resistor kwizibane ze-LED zilawula ukuhamba kwangoku ngaphakathi kwemicu. Ukuba izilungiso zihamba ngomsinga ogqithisileyo, zonakala. I-Resistors ifakwe ukukhusela imeko enjalo. Igcina i-voltage kunye nokuhamba kwangoku, iqinisekisa ukusebenza kakuhle.
- Umphathi
I-capacitor isetyenziswa kwiintambo ze-LED ukuqinisekisa ukukhanya okulinganayo kunye nokungaguqukiyo. Izinzisa unikezelo lwamandla kwaye inciphisa ukukhenkceza okanye ezinye iziphumo zombane ezingafunekiyo. Nangona kunjalo, zonke iintambo ze-LED azizi kunye nee-capacitors. Ngokuqhelekileyo ifumaneka kwizibane ze-strip eziphambili ezine-ICs; Imichilo ye-LED esisiseko inokuba nayo i-capacitor.
- lobuceducedu
Kubalulekile ukugcina isalathiso sokuhamba kwangoku kuzo zonke iintambo ze-LED. Ukuba, ngethuba, i-current igeleza ngokuphambeneyo, iya kulimaza ii-chips ze-LED. Ngenxa yezi zizathu, iidiode zisetyenziselwa ukuqinisekisa ukuhamba kwangoku kuphela kwicala elinye. Ezi zixhobo ze-semiconductor nazo zinamandla okulawula umbala. Umzekelo, kwi Imichilo ye-LED ye-RGBX, ungalawula ubunzulu bombala ngamnye (obomvu, oluhlaza, & bhlowu) ngokunyenyisa ukudlula kwangoku kwidiode nganye. Ke, ikuvumela ukuba udale ukuya kuthi ga kwi-16 yezigidi ze-hues. Jonga oku ukuze ufunde ngakumbi: I-RGB vs. RGBW vs. RGBIC vs. RGBWW vs. RGBCCT LED Strip Lights.
- Imizila yobhedu
Umkhondo wobhedu kwi-PCB yeentambo ze-LED zisebenza njengomqhubi wombane. Yenza indlela yangoku equkuqelayo ukusuka kumthombo wamandla ukuya kwimigca ye-LED yomntu kunye namanye amacandelo.

Iziseko ezisisiseko kwiVoltage
Umbane wemigca ye-LED ixhomekeke kwizinto ezimbini-
IVoltage yee-LEDs, izinto zazo, kunye noBonelelo lwaMandla
Xa umisela amandla ombane kwizibane ze-LED, kufuneka uqwalasele izinto ezintathu. Ezi zezi zilandelayo-
- Umbane we-LED
Ii-LED ezisetyenziswa kwizibane zestrip zinemfuno yombane ngamnye. Lo mbane udla ngokubizwa ngokuba yi-'Forward Voltage' okanye 'VF.' Ngowona mbane uncinci ekufuneka i-LED ikhuphe ukukhanya. Imfuno yalo mbane iyahluka ngohlobo kunye nombala we-LED. Umzekelo, i-LED emhlophe ihlala idinga malunga ne-3 ukuya kwi-3.4 volts. Oku kunokwahluka kweminye imibala yokukhanya. Itshathi engezantsi ikubonisa uluhlu lwamandla ombane angaphambili ee-LED zemibala eyahlukeneyo-
| Umbala we-LED | Uluhlu lweVF oluqhelekileyo |
| Bomvu | I-1.8 ukuya kwi-2.1 volts |
| intlaka elukhuni yokuhombisa ijuwelari | I-2 ukuya kwi-2.2 volts |

Imichilo ye-LED yenziwe ngamacandelo ahlukeneyo. Ezi ziquka- resistors, diodes, kunye capacitors. Umbane ngamnye kula macandelo kufuneka uhambelane nombane we-LED. Ukuba i-voltage ayihambelani, inokonakalisa amacandelo okanye ikhokelele ekungasebenzini kakuhle.
- Umbane oNikezela ngeVolthi
Umbane wobonelelo lwamandla waziwa ngokuba yi-'input voltage' okanye 'i-supply voltage.' Ngamandla ombane angaphandle anikezelwa kwi-fixture. Njengoko izibane ze-strip ze-LED zi-voltage-sensitive, kubalulekile ukuqinisekisa ukuba umbane wee-LED kunye nezinto zazo zihambelana nombane womthombo wamandla. Umzekelo- ukuba unomgca we-LED we-12-volt, kufuneka usebenzise umbane we-12-volt. Ukuba usebenzisa amandla ombane aphezulu okanye asezantsi, izibane ze-LED aziyi kusebenza kakuhle.
Ulungelelwaniso lwee-LEDs
Ii-LED zokukhanya komcu we-LED zinokucwangciswa kwiindidi ezimbini zoqwalaselo- uthotho kunye nokuhambelana. Oku kuxoxwe ngezantsi-
Uluhlu lweesekethe
Kwisekethe yochungechunge, ii-LED zePCB zixhunyiwe ekupheleni ukuya ekupheleni. Oko kukuthi, ukuphela kwesinye i-chip ye-LED kuqhagamshelwe ekuqaleni kwenye. Ngenxa yoko, ikhoyo ngoku ihamba nge-LED nganye ngokulandelelana. Kwisekethe yochungechunge, inani elilinganayo langoku lidlula kuzo zonke ii-LED, kwaye i-voltage yongezwa. Umzekelo, ukuba une-n inani le-LED kumgca we-LED, i-voltage iyonke yokukhanya kwe-strip iya kuba ngamaxesha e-VF ye-LED enye.

Indlela yokunciphisa i-LED Strip Voltage Drop?
Ukukhanya kunye nokuphuma kokukhanya ngokubanzi kuchaphazeleka kakubi ngenxa yokuhla kwamandla ombane. Nazi iindlela ezilandelayo onokuthi unciphise ukuhla kwamandla ombane we-LED ngeendlela ezilandelayo-
1. Sebenzisa i-High Voltage LED Strips
Imichilo ye-LED ene-high-voltage ayinakukwazi ukuhla kwamandla ombane. Ukuba ujongene nemiba yokuhla kwamandla ombane usebenzisa i-12V okanye i-24V imichilo ye-LED, ndicebisa ukuba ukhethe imicu ye-LED ene-voltage ephezulu. Ingaba yi-48Vdc okanye i-36Vdc ye-LED strip okanye i-110Vac, i-120Vac (okanye ngaphezulu) ehambelana nenjongo yakho yokukhanyisa. Kodwa nantoni na oyikhethayo, qiniseka ukuba i-voltage ye-strip ye-LED iyahambelana nombane womthombo wamandla.
2. Yenza mfutshane Ubude bemicu ye-LED
Ukuhla kwe-voltage kunye nokuxhatshazwa kokuhamba kwangoku kwanda ngokunyuka kobude.
Ubude ⬆ Voltage ⬆ I-Volt Drop ⬇
Kungenxa yoko le nto ukunciphisa ubude bomgca we-LED kuya kunciphisa ukuhla kombane. Ukwazi ngakumbi malunga nobude bemigca ye-LED kunye nombane wabo, jonga oku- Zeziphi ezona zibane zide kakhulu ze-LED Strip?
3. I-Parallel Wiring Multiple Strips
Xa udibanisa iintambo ezininzi ze-LED ukwandisa ubude, kubangela ukuhla kwamandla ombane. Ngenxa yoko, ukuqaqamba komtya we-LED kuqala ukufiphala kancinci njengoko ubude bukhula. Ukunqanda imiba enjalo, qhagamshela iingcingo ezihambelanayo ukusuka kumthombo wamandla ukuya kumcu we-LED ngamnye osanda kufakwa. Oku kuya kunciphisa ukuhla kwamandla ombane.
4. Sebenzisa i-PCB eThiyeleyo neBanzi
Onke amacandelo e-LED strip acwangciswe ngaphakathi kwebhodi yesekethe eprintiweyo okanye iPCB. Ikwanayo ne-resistor. Njengoko ubude bunyuka, ukuchasana kuyanda, okubangela ukuhla kwe-voltage. Kodwa unganciphisa ukuhla kwamandla ombane ngokusebenzisa iPCB etyebileyo nebanzi.
Ngaba kufuneka unikeze ngokuthe ngqo iVoltage ecacisiweyo?
Ii-LED zinobuthathaka kwivoltheji. Kungenxa yoko le nto kubalulekile ukubonelela ngevoltheji echanekileyo kwizibane ze-LED strip ukusebenza ngokugqibeleleyo. Nangona kunjalo, kukho uluhlu lonyamezelo apho ii-LED zinokuthatha i-voltage. Ukuba i-voltage enikeziweyo idlula inqanaba lokunyamezela, ukulungiswa kuya konakala.
Umbane osebenzayo wee-LED waziwa njengevoltheji yangaphambili okanye iVF. Ngokomzekelo, ukuba i-VF ye-LED yi-3.2 volts kunye nokunyamezela kwe-± 0.1 volts. Oku kubonisa ukuba ukukhanya kwe-strip ye-LED kunokusebenza ngokufanelekileyo ngaphakathi koluhlu lwe-3.1 volts ukuya kwi-3.3 volts. Ukuba i-voltage enikeziweyo idlula le nto, iya kuyonakalisa i-LED.
