LED Power Drive Ulwazi

Ukutshatyalaliswa kobushushu, amandla okuqhuba, kunye nomthombo wokukhanya zezona ndawo zibaluleke kakhulu kwimveliso yokukhanyisa i-LED. Nangona ukutshatyalaliswa kobushushu kubaluleke kakhulu, umphumo wokutshatyalaliswa kobushushu uchaphazela ngokuthe ngqo umgangatho wobomi bemveliso yokukhanyisa, kodwa umthombo wokukhanya uyinxalenye ephambili yemveliso yonke. Ubomi bomthombo wamandla okuqhuba ngokwawo kunye nokuzinza kwemveliso yangoku kunye ne-voltage nazo zinempembelelo enkulu kumgangatho wobomi bemveliso.

Umbane womqhubi we-LED uyimveliso ye-accessory. Umgangatho wamandla kwimarike okwangoku awulingani. Olunye ulwazi malunga namandla omqhubi we-LED lunikezelwa ngezantsi.　

Iimpawu zamandla okuqhuba i-LED

　　(1) Ukuthembeka okuphezulu

Ngokukodwa njengamandla okuqhuba izibane zesitalato ze-LED, ifakwe kwindawo ephakamileyo, ukugcinwa kungenakulungeleka, kunye neendleko zokulondoloza nazo zikhulu.

(2) Ukusebenza okuphezulu

Ii-LED ziimveliso ezigcina amandla, kwaye ukusebenza kakuhle konikezelo lwamandla okuqhuba kuphezulu. Kubaluleke kakhulu ukutshabalalisa ubushushu obuvela kumbane ofakwe kwi-fixture. Umthombo wamandla unokusebenza okuphezulu, ukusetyenziswa kwawo kwamandla kuncinci, kwaye ukushisa okwenziwa kwisibane kuncinci, okunciphisa ukunyuka kweqondo lokushisa kwesibane. Kuyinzuzo ukulibazisa ukubola kokukhanya kwee-LEDs.

(3) Amandla aphezulu

Umba wamandla ziimfuno zomthwalo wegridi. Ngokubanzi, akukho zikhombisi ezinyanzelekileyo zezixhobo zombane ezingaphantsi kwe-70 watts. Nangona amandla ombane ombane omnye onegunya eliphantsi anempembelelo encinci kwigridi yamandla, isixa sokukhanyisa esisetyenziswa ebusuku sikhulu, kwaye umthwalo ofanayo ugxininiswe kakhulu, oya kubangela ungcoliseko olunzulu kwigridi yamandla. Ngama-watts angama-30 ukuya kwii-watts ze-40 zamandla omqhubi we-LED, kuthiwa kwixesha elizayo elingekude, kunokubakho izikhombisi ezithile zezinto zamandla.

(4) Indlela yokuqhuba

Kukho iindidi ezimbini zetrafikhi: enye ingumthombo wamandla ombane rhoqo kwimithombo emininzi yangoku, kwaye umthombo ngamnye okhoyo ngoku unika amandla kwi-LED nganye ngokwahlukileyo. Ngale ndlela, ukudibanisa kuguquguqukayo, kwaye zonke iimpazamo ze-LED azichaphazeli umsebenzi wezinye ii-LED, kodwa iindleko ziya kuba phezulu. Omnye unikezelo lwamandla lwangoku ngokuthe ngqo, oluyimowudi yokuqhuba eyamkelwa yi "Zhongke Huibao". Ii-LEDs zisebenza ngokulandelelana okanye ngokuhambelanayo. Inzuzo yayo kukuba iindleko ziphantsi, kodwa ukuguquguquka kubi, kwaye kuyimfuneko ukuxazulula ukungaphumeleli okuthile kwe-LED ngaphandle kokuchaphazela ukusebenza kwezinye ii-LED. Ezi ntlobo zimbini zihlala ixeshana. Imowudi yonikezelo lwamandla ephumayo yangoku yamatshaneli amaninzi iya kuba ngcono ngokwexabiso kunye nokusebenza. Mhlawumbi lukhokelo oluphambili kwixesha elizayo.

(5) Ukukhuselwa ngokunyuka

Ukukwazi kwee-LED ukumelana nokunyuka kumbi kakhulu, ngakumbi ngokuchasene namandla ombane obuyela umva. Kwakhona kubalulekile ukuqinisa ukhuseleko kule ndawo. Ezinye izibane ze-LED zifakwe ngaphandle, njengezibane zesitrato ze-LED. Ngenxa yokuqalisa komthwalo wegridi kunye nokungeniswa kwezithonga zombane, ukunyuka okuhlukeneyo kuya kuhlaselwa kwi-system yegridi, kwaye ezinye iinqwelo ziza kubangela umonakalo we-LED. Umbane wamandla omqhubi we-LED kufuneka ube namandla okucinezela ukungena kwee-surges kunye nokukhusela i-LED kumonakalo.

(6) Umsebenzi wokukhusela

Ukongeza kumsebenzi oqhelekileyo wokukhusela, ukunikezelwa kwamandla ngokufanelekileyo kwandisa ubushushu be-LED impendulo engalunganga kwimveliso eqhubekayo yangoku ukukhusela ubushushu be-LED ukuba bube phezulu kakhulu; kufuneka ihlangabezane neemfuno zemigaqo yokhuseleko kunye nokuhambelana kwe-electromagnetic.
