Indlela yokusombulula ingxaki yokufudumeza imichilo yokukhanya kwe-LED

Izizathu kunye nezisombululo zokufudumeza imichilo yokukhanya kwe-LED

Sihlala sisebenzisa iimveliso ze-LED ebomini bethu, kwaye imichilo yokukhanya ye-LED isetyenziswe ngokubanzi ekuhombiseni nasekuhombiseni kwiinkalo ezahlukeneyo kwiminyaka yakutshanje. Kwiimeko ezininzi, kufuneka basebenze ixesha elide, nto leyo eya kubangela ukuba zonakaliswe ngenxa yamandla exesha elide. ifiva. Ngoko zeziphi izizathu zomkhuhlane kunye nendlela yokuyicombulula emva komkhuhlane? Masizixubushe kunye.

1. Izizathu zokufudumeza imichilo yokukhanya

Kukho izizathu ezininzi zobushushu bomcu wokukhanya, kuquka le miba ilandelayo:

1. Ibangelwa kukufudumeza kwe-LED

I-LED ngumthombo wokukhanya obandayo othi ngokwethiyori awuvelisi ubushushu. Nangona kunjalo, kwizicelo ezisebenzayo, ngenxa yokuguqulwa kwe-elektroniki okungafezekanga kunye nokusebenza kakuhle kwe-photoelectric, umlinganiselo othile wokushisa uya kuveliswa kwinqanaba elithile, elibangela ukuba umbane wesibane ushushu.

2. Ukutshatyalaliswa kobushushu obungalunganga bomgca wokukhanya

Ukutshatyalaliswa kobushushu obungalunganga bomgca wokukhanya kukwasisizathu esibalulekileyo sobushushu bomgca wokukhanya. Ukukhutshwa kobushushu okungekuhle kwemigca yokukhanya kubangelwa ikakhulu yimiba efana neengcingo ezingafanelekanga, uyilo olulambathayo lweradiyetha, okanye izitsi zobushushu ezivaliweyo. Xa ukutshatyalaliswa kobushushu kungalunganga, umgca wokukhanya uya kudlula, okukhokelela kubomi obufutshane bomgca wokukhanya.

3. Umtya wokukhanya ugcwele kakhulu

Ukulayishwa kakhulu kwemicu yokukhanya sesinye sezizathu zokuba kutheni imicu yokukhanya ishushu. Xa okwangoku umgca wokukhanya umelana mkhulu kakhulu, uya kubangela ukuba umgca wokukhanya ugqithise, ubangele ukuba izinto ziguge, zikhokelela kwiisekethe ezimfutshane, iisekethe ezivulekileyo, njl.

1. Umba weSekethe: Iimpawu zombane ezisetyenziswa ngokuqhelekileyo kwiintambo zokukhanya kwe-LED ziyi-12V kunye ne-24V. I-12V yi-3-string ye-multi-channel parallel structure, kunye ne-24V yi-6-string ye-multi-channel parallel structure. Izibane ze-LED zisetyenziswa ngokudibanisa amaqela amaninzi eentsimbi zesibane. Ubude obuthile bemicu yokukhanya enokuthi idibaniswe ininzi yokwenza ububanzi besiphaluka kunye nobukhulu bephepha lobhedu ngexesha loyilo. Ukuqina kwangoku ukuba umtya wokukhanya unokumelana nokuhambelana nendawo enqamlezayo yomgca. Kufuneka ubeke ingqalelo koku xa ufaka umtya wokukhanya. Ukuba ubude boqhagamshelo lomgca wokukhanya budlula okwangoku bunokumelana ngexesha lofakelo, ngoko ke umtya wokukhanya uya kuthi Xa usebenza, ngokuqinisekileyo uya kuvelisa ubushushu ngenxa yomthwalo ogqithisiweyo wangoku, oya kuwonakalisa kakhulu ibhodi yesekethe kwaye unciphise ubomi benkonzo yokukhanya. strip.

2. Ukuveliswa: Imichilo yokukhanya kwe-LED zizo zonke izakhiwo ezihambelanayo. Xa isiphaluka esifutshane senzeke kwiqela elinye, umbane wamanye amaqela kumgca wokukhanya uya kwanda, kwaye ukushisa kwe-LED kuya kwanda ngokufanelekileyo. Le nto yenzeka kakhulu kwisibane sesibane se-5050. Xa nayiphi na i-chip yesibane sesibane se-5050 i-short-circuited, i-current ye-short-circuited bead yesibane iya kuphinda kabini, kwaye i-20mA iya kuba yi-40mA, kwaye ukukhanya kwesibane kuya kuncitshiswa. Kuya kukhanya ngakumbi kwaye ngexesha elifanayo kubangele ukushisa okukhulu, ngamanye amaxesha kutshisa ibhodi yesiphaluka kwimizuzu embalwa. Yenza ukuba umgca wokukhanya we-LED ucinywe. Nangona kunjalo, le ngxaki ayibonakali, kwaye ngokuqhelekileyo ayinakwenzeka ukuba iqatshelwe, kuba isiphaluka esifutshane asichaphazeli ukukhanya okuqhelekileyo komgca wokukhanya, ngoko ke abantu abambalwa bajonga rhoqo. Ukuba umhloli ujonga kuphela ukuba umgca wokukhanya ukhupha ukukhanya kwaye akanikeli ngqalelo ukuba ukukhanya kwe-LED akuqhelekanga, okanye ukhangele kuphela inkangeleko ngaphandle kokukhangela ngoku, ngoko isizathu sokuba i-LED ishushu iya kuhlala ingahoywa. izakubangela Abasebenzisi abaninzi bathi imicwe yokukhanya iba shushu kodwa abafumani nasiphi na isizathu.

Isisombululo:

1. Khetha umgca wokukhanya kunye nokusebenza kakuhle kokutshatyalaliswa kobushushu

Xa uthengela umgca wokukhanya, unokukhetha umgca wokukhanya kunye nokusebenza kakuhle kokutshatyalaliswa kobushushu, okunokunciphisa ngokufanelekileyo ingxaki yokutshatyalaliswa kobushushu bomgca wokukhanya kunye nokuthintela umgca wokukhanya ekugqithiseni kwaye ubangele ukusilela.

2. Yenza uyilo olulungileyo lokuphelisa ubushushu kumtya wokukhanya

Kwezinye iindawo ezifuna ukusetyenziswa ixesha elide, umphumo wokutshatyalaliswa kobushushu bomgca wokukhanya unokuphuculwa ngokufaka i-radiator okanye i-heat sinks. Isixhobo sokuchitha ubushushu sinokuthi siyilwe kuyilo lomgca wokukhanya ukuze kuphuculwe ngokufanelekileyo amandla okuphelisa ubushushu bomtya wokukhanya.

3. Kuphephe ukulayisha kakhulu umtya wokukhanya

Xa usebenzisa imicu yokukhanya, zama ukunqanda ukulayisha ngaphezulu, khetha imicu yokukhanya efanelekileyo kunye nezixhobo zombane, kwaye uqhube iingcingo ezifanelekileyo ukunqanda ukugcwala kwexesha elide kwemichilo yokukhanya.

1. Uyilo lomgca:

Ukuqwalasela ukunyamezela kwangoku, isiphaluka kufuneka siyilwe ukwenza i-wiring ibe banzi kangangoko kunokwenzeka. Isithuba se-0.5mm phakathi kwemigca sanele. Kungcono ukugcwalisa yonke indawo. Ukungabikho kweemfuno ezikhethekileyo, ubukhulu be-foil yobhedu kufuneka bube bubunzima ngokusemandleni, ngokubanzi 1 ~ 1.5 OZ. Ukuba isiphaluka senziwe kakuhle, ukufudumeza komgca wokukhanya kwe-LED kuya kuncitshiswa kakhulu.

2. Inkqubo yokuvelisa:

(1) Xa udibanisa iyunithi yesibane, zama ukungavumeli ukudityaniswa kwetoti phakathi kweepads ukuphepha ukuwelda iisekethe ezimfutshane ezibangelwa kukuprintwa kakubi.

(2) Umtya wokukhanya kufuneka kwakhona uthintele umjikelezo omfutshane xa upakisha, kwaye uzame ukuwuvavanya ngaphambi kokusetyenziswa.

(3) Phambi kokuba ugalele kwakhona, qala ujonge indawo ekuyo kuyo, uze wenze ukuqukuqela kwakhona.

(4) Emva kokuhamba kwakhona, ukuhlolwa okubonakalayo kuyadingeka. Emva kokuqinisekisa ukuba akukho siphaluka esifutshane kwisibane sesibane, qhuba uvavanyo lwamandla. Emva kokukhanya kombane, qwalasela ukuba ukukhanya kwe-LED kuqaqambe ngokungaqhelekanga okanye kumnyama. Ukuba kunjalo, ukulungisa ingxaki kuyafuneka.

Eli nqaku lihlalutya izizathu zokufudumeza imichilo yokukhanya kwaye iphakamisa iindlela zokusombulula ingxaki yokufudumeza imichilo yokukhanya. Siyathemba ukuba inokunceda wonke umntu ukuba asebenzise ngcono kwaye akhethe imicu yokukhanya kwaye aphephe ukusilela okubangelwa kukushisa okugqithisileyo kwemicu yokukhanya.
