Ukulungisa kabusha i-speedometer nge-LED: Isinyathelo ngesinyathelo imiyalelo

Ukukhubazeka okwenzeka ezimotweni ezindala kubonakala kuphela ngemva kwesikhashana, njengoba kubonakala kancane kancane: i-speedometer yakho ikhanya ibuthakathaka futhi ibuthakathaka. Lokhu kubangelwa izibani ze-incandescent, ezingase zitholakale kumadeshibhodi ezimoto. Isixazululo esifanele siwumthombo wokukhanya ozothatha indawo yezibani zendabuko: i-LED.

Ayini ama-LED?

I-diode ekhipha ukukhanya isifinyezo se I-Light Emitting Diode , ingxenye ye-elekthronikhi esetshenziselwa ukukhiqiza ukukhanya. Ngezindlela eziningi, ihluke ezibani ze-incandescent.

I-Diode yilokho okuthiwa i-semiconductor , okusho ukuthi iqhuba okwamanje endaweni eyodwa. Njengomthetho, lapho ushintsha izibani ze-incandescent ngama-LED, lokhu akunandaba. .

Ukukhanyisa okusha ine-polarity efanele efektri. Uma ukhetha ukuvumelanisa ukukhanya kweqoqo lensimbi ngensimbi yokunamathisela, qaphela ukumaka. Kokubili ama-LED kanye ne-PCB ahlala amakwe ngokucacile . Indlela yokunquma kahle i-polarity futhi ugweme amaphutha e-solder izochazwa ngokulandelayo.

Izinzuzo zama-LED

Ama-LED anezinzuzo eziningi ezibalulekile ngaphezu kwezibani ze-incandescent. isibonelo:

– insizakalo eyandisiwe - ukuchithwa kokushisa okuncane - ukukhanya okukhanyayo – induduzo eyengeziwe

Kuncike ekukhetheni ikhwalithi ehloniphekile lapho ufaka ama-LED bangahlala impilo yonke yemoto ngisho nangaphezulu. Ngakho-ke, kungase kufaneleke qaqa ama-LED ashintshiwe ku-speedometer kanye nokusayina ngenkathi ushayela imoto. Angasetshenziswa emotweni elandelayo ngaphandle kwezinkinga.

• Ama-LED ayadla amandla amancane kakhulu kunezibani ze-incandescent.
• Bazoguqula amandla engeziwe ekukhanyeni futhi ikhiphe ukushisa okuncane. Lokhu kungaba inzuzo kuphela endaweni ewumngcingo ngemuva kwephaneli yedeshi.
• Ama-LED ayakhanya ekhanya kakhulu futhi enamandla kakhulu kunamalambu e-incandescent ngaphandle kokukhiqiza ukushisa.

Akukhona lokho kuphela, ama-LED angafiphazwa ngendlela othanda ngayo.

• Isizukulwane sakamuva se-RGB LEDs ukunikeza okuthakazelisayo imiphumela yokukhanyisa .
• I-RGB imfushane yokuthi Luhlaza okwesibhakabhaka oluBomvu , imibala eyinhloko ekwazi ukukhiqiza noma yimuphi umbala wokukhanya.
• I-RGB LED ingenziwa ngezifiso umbala wakho owuthandayo noma ukhanyise i-speedometer ngombukiso wokukhanya omangalisayo.

Ukuguqulwa kwe-LED kwabaqalayo

Ukuguqula i-speedometer isuka ku-incandescent iye kuma-LED kulula kakhulu. Konke okudingayo:

– imiyalelo yokuhlakaza iqoqo lezinsimbi - amathuluzi afanele – izibani ezigunyaziwe - ukubekezela nezandla eziqinile

1.  Amalambu e-incandescent anamathiselwe ngemuva kweqoqo lezinsimbi kusetshenziswa izixhumi ezijikelezayo. Ukuze ufinyelele kuzo, udinga ukususa iqoqo lezinsimbi.

• Kuye ngohlobo lwemoto, lokhu kungaba umsebenzi onzima. . Ngazo zonke izindlela, zama ukususa iphaneli yensimbi ngaphandle kokukhipha isondo lokuqondisa.
• I-airbag ihlanganiswe esiteringini. Ukususwa kudinga ubuchwepheshe .

2.  Kunezinto ezimbili okufanele uzikhumbule lapho ususa ideshibhodi. Isembozo se-plexiglass sizacile futhi singaphuka kalula . Ukujika kwe-cluster okungajwayelekile kuvame ukwanele ukubangela ukwephulwa. Ngeshwa, ikhava ayitholakali njengengxenye eyisipele ehlukile. Okuwukuphela kwenketho manje ukuvakashela i-junkyard noma ubheke izikhangiso ezihlukanisiwe. ukuze uthole ukufakwa esikhundleni.

3.  Ingilazi yefasitela akufanele ikhishwe lapho kushintsha ama-incandescent ama-LED.

• Uma ilimele noma iwiswe ngephutha ungathinti okokufakwayo ngezandla ezingenalutho.
• Isendlalelo esimnyama se-matte asihambisani nokujuluka kwezintende.
• Amabala awasuki . Ama-LED okushintsha nawo ayatholakala njenge ama-LED ashintshiwe , okusho ukuthi sezivele zivumelaniswe nezibani ezitholakalayo.

Ngakho-ke, le nqubo elandelayo iyanconywa:

1. Susa yonke i-speedometer. 2. Sebenzisa i-speedometer endaweni yokusebenza ehlanzekile njengetafula. 3. Sebenzisa i-speedometer ngamagilavu ​​kakotini.

Lapho udiliza i-speedometer, izibani ze-incandescent zisuswa ngamapuleti ekhala yenaliti. Isokhethi ephumela ngaphandle iyaboshelwa futhi ijikeleziswa ngo-90°. Khona-ke ingakhishwa.

Manje ama-LED afakwe ngokulandelana okuphambene, i-speedometer ifakwe futhi - isilungile.

Ukuguqulwa kwe-LED

Namuhla, izimoto eziningi zifakwe izibani ze-LED ku-speedometer efektri.

Abanye abakhiqizi, ngenxa yezizathu zomnotho, basebenzisa izibani zekhwalithi ephakathi. Ngakho-ke, kungenzeka ukuthi ama-LED okuthiwa ahlala isikhathi eside alahlekelwa ukukhanya kwawo ngaphambi kwesikhathi noma ahluleke ngokuphelele.

Ukushintshwa kwabo kuyinkimbinkimbi futhi kufanele kusetshenzwe ngokucophelela kusenesikhathi.

Kunezindlela ezimbili zokuguqula i-speedometer:

- Ukushintshwa kwezingxenye ezidayisiwe. - Ukushintshela emigqeni ye-LED.

Ukushintsha ama-LED athengisiwe kuyindlela elungile nephephile ngolwazi olwanele. Uma uhlasela ngokungakhethi ideshibhodi ngensimbi yokunamathisela, cishe uzokwenza umonakalo omkhulu. Into ebaluleke kakhulu lapho i-soldering LEDs i-polarity. .

Ngizosho kusengaphambili: nakuba ukuguqulwa kwe-polarity ngeke kubangele ukuba ikhebula livutha, i-diode ngeke isebenze. Uma ungakubonanga lokhu ngaphambi kokusetha kabusha i-speedometer, wonke umsebenzi ube yize.

Ukunqunywa kwe-polarity ye-LED

Ama-LED e-SMD kuphela asetshenziselwa ukukhanyisa ideshibhodi.

• I-SMD imele i-Surface Mount Device , i.e. ingxenye idayiswa ngqo endaweni ye-PCB.

Umklamo wendabuko Izingxenye eziningi ze-elekthronikhi zinezikhonkwane ezidinga ukufakwa emigodini ebhodini lesifunda eliphrintiwe bese lithengiswa ngemuva. Lo mklamo uyinkimbinkimbi kakhulu futhi awufaneleki ngokukhethekile ukuhlanganiswa okuzenzakalelayo, kancane kancane ukuhlanganisa ngesandla. Ngezinjongo ze-DIY »Ama-LED anamaphini asatholakala.

I-polarity inqunywa ubude babathintwayo:

• Okude kuyi-anode noma isigxobo esihle
• Umfushane i-cathode noma isigxobo esinegethivu .
• Isikhundla sabo sikhonjiswe ebhodini lesifunda eliphrintiwe ngezimpawu + noma - noma, ngokuhlukile, ngezinhlamvu "A" noma "C".
• Izikhonkwane ziyanqanyulwa ngemva kokudayiswa, ngakho-ke ama-Pin LED asetshenzisiwe ngeke aphinde asetshenziswe.

1. I-Soldering SMD ilula kakhulu. . Kungcono ukusebenzisa izinsimbi ezimbili ze-soldering. I-SMD ishisa kuzo zombili izigxobo bese ibeka eceleni ngemva kwemizuzwana embalwa .
2. I-soldering inzima . Kodwa-ke, izimpawu ze-SMD polarity zisobala kakhulu: I-SMD ihlale ishoda ekhoneni .

Lelikhona elingekho limakwe ku-PCB ngophawu . I-SMD isethwe ohlangothini lokuzungezisa, ikhombisa ikhona elingekho, inqamule uhlamvu.

Ukufaka wonke ama-SMD kumshini wokubonisa izinga lejubane, ekuqaleni efakwe ama-LED, kuzothatha amahora ambalwa. Izimo - amathuluzi alungile, isandla esiqinile, izimo zokusebenza ezikahle kanye nolwazi oluhle kakhulu.  Kukhona enye indlela edinga umsebenzi othile, kodwa ingase iholele kumphumela owanelisayo.

Ukuguqula ama-LED ngama-Light Strip

Ama-LED, ikakhulukazi ama-RGB LED, ayatholakala kulokho okubizwa imichilo yokukhanya nge-SMD ithengiswe kubo. Lolu hambo lunganqunywa noma yikuphi. Abaningi amashuni enziwe ekhaya hlela ukuguqulwa kwabo ku-LED kanje:

– Khipha iphaneli yezinsimbi. - Khipha ifasitelana lewindi kumshini. - Namathisela umugqa we-LED onqenqemeni. - Xhuma umugqa we-LED kusekethe yedeshibhodi. - Faka kabusha yonke into.

• Ingilazi yewindi kufanele ikhishwe kudeshibhodi ngakho kufanele ugqoke  amagilavu ​​kakotini .
• Ideshibhodi manje inokukhanya okungaqondile kwe-ambient . Lesi sixazululo sifanelekile ngokukhanya okujabulisayo kwe-rev gauge, iwashi, i-speedometer, igeji yezinga lokushisa kwenjini kanye nawo wonke amanye amathuluzi esandla.
• Lesi sixazululo asihlonyiselwe ukuphatha amasignali, iyahlola  izinkomba  injini, izinga lokushisa lenjini, ibhethri lamanje, izinkomba ze-ABS ne-airbag .
• Lapha uncike ezibani zendabuko.
