Ngokomgaqo, emvaIzibane ze-LEDXa zidityaniswe zibe ziimveliso ezigqityiweyo, kufuneka zivavanyelwe ukuguga. Injongo ephambili kukubona ukuba i-LED yonakele na ngexesha lenkqubo yokuhlanganisa nokujonga ukuba umbane uzinzile na kwindawo enobushushu obuphezulu. Enyanisweni, ixesha elifutshane lokuguga alinaxabiso lokuvavanya isiphumo sokukhanya. Uvavanyo lokuguga luyaguquguquka ekusebenzeni ngokwenene, olungenakwanelisa kuphela iimfuno zemigangatho efanelekileyo, kodwa lukwaphucula nokusebenza kakuhle kwemveliso. Namhlanje, umenzi wezibane ze-LED uTIANXIANG uza kukubonisa indlela yokwenza oko.
Ukuvavanya imigangatho yokuguga kwezibane ze-LED, kuyimfuneko ukusebenzisa izixhobo ezibini eziphambili zokuvavanya, iibhokisi zovavanyo lwamandla kunye neerakhi zovavanyo lokuguga. Uvavanyo lwenziwa phantsi kobushushu obuqhelekileyo, kwaye ixesha lihlala libekwe phakathi kweeyure ezi-6 ukuya kwezili-12 ukuqinisekisa ukusebenza kwezibane ze-LED ngamaxesha ahlukeneyo. Ngexesha lenkqubo yovavanyo, nikela ingqalelo kwizalathisi eziphambili ezifana nobushushu bezibane, i-voltage yokuphuma, i-power factor, i-voltage yokufaka, i-input current, ukusetyenziswa kwamandla, kunye ne-output current. Ngale datha, ungayiqonda ngokupheleleyo utshintsho lwezibane ze-LED ngexesha lenkqubo yokuguga.
Ubushushu bezibane yenye yezona zinto zibalulekileyo zokuvavanya ukuguga kwezibane ze-LED. Njengoko ixesha lokusetyenziswa kwezibane ze-LED lisanda, ubushushu bangaphakathi buyaqokelelana kancinci kancinci, nto leyo enokubangela ukuba ubushushu bunyuke. Kuvavanyo lokuguga, ukurekhoda utshintsho lobushushu bezibane ngamaxesha ahlukeneyo kunceda ukugweba uzinzo lobushushu bezibane ze-LED. Ukuba ubushushu bunyuka ngendlela engaqhelekanga, kusenokwenzeka ukuba ukusebenza kobushushu bangaphakathi kwesibane se-LED akukuhle, nto leyo ebonisa ukuba isantya sokuguga siyakhawuleza.
I-voltage yokukhupha luphawu oluphambili lokulinganisa ukusebenza kwezibane ze-LED. Ngexesha lovavanyo lokwaluphala, ukujonga rhoqo ukuguquguquka kwe-voltage yokukhupha kunokunceda ekumiseleni uzinzo lwe-voltage yesibane se-LED. Ukwehla kwe-voltage yokukhupha kunokubonisa ukuba ukusebenza kakuhle kwesibane se-LED kuye kwehla, nto leyo ebonisa inkqubo yokwaluphala. Nangona kunjalo, ukuba i-voltage yokukhupha itshintsha ngequbuliso okanye yehla kakhulu, kusenokwenzeka ukuba isibane se-LED siye saphola kwaye kufuneka uphando olongezelelweyo.
I-Power factor luphawu olubalulekileyo lokulinganisa ukusebenza kakuhle kokuguqulwa kwamandla kwezibane ze-LED. Kuvavanyo lokwaluphala, ngokuthelekisa umlinganiselo wamandla okufaka amandla kumandla okukhupha, kunokuqinisekiswa ukuba ukusebenza kakuhle kwamandla kwesibane se-LED kuhlala kuzinzile na. Ukwehla kwe-power factor kunokubonisa ukuba ukusebenza kakuhle kwamandla kwesibane se-LED kuye kwehla ngexesha lenkqubo yokwaluphala, into eyenzeka ngokwendalo kwinkqubo yokwaluphala. Nangona kunjalo, ukuba i-power factor yehla ngokungaqhelekanga, kusenokwenzeka ukuba kukho ingxaki ngamacandelo angaphakathi esibane se-LED, ekufuneka isonjululwe ngexesha.
I-voltage yokufaka kunye ne-input current zibaluleke ngokulinganayo kwiimvavanyo zokwaluphala. Zinokubonakalisa ukusasazwa kwangoku kwesibane se-LED phantsi kweemeko ezahlukeneyo zokusebenza. Ngokurekhoda utshintsho kwi-voltage yokufaka kunye ne-input current, ukuzinza kokusebenza kwesibane se-LED kunokufunyanwa. Ukuguquguquka kwi-voltage yokufaka okanye ukusasazwa okungaqhelekanga kwe-input current kunokubonisa iingxaki zokusebenza kwezibane ze-LED ngexesha lenkqubo yokwaluphala.
Ukusetyenziswa kwamandla kunye nomsinga wombane ophumayo zizibonakaliso ezibalulekileyo zokulinganisa ukusebenza kwezibane ze-LED. Kuvavanyo lokwaluphala, ukujonga ukusetyenziswa kwamandla kunye nomsinga wombane ophumayo wezibane ze-LED kunokumisela ukuba ukusebenza kwazo okukhanyayo kuhlala kuzinzile na. Ukusetyenziswa kwamandla okunyukayo okanye ukuguquguquka okungaqhelekanga kumsinga wombane ophumayo kunokubonisa ukuba isibane se-LED siyaguga ngokukhawuleza, kwaye kufuneka kuqwalaselwe utshintsho lwaso lokusebenza.
Umenzi wezibane ze-LEDUTIANXIANG ukholelwa ukuba ngokuhlalutya ngokupheleleyo idatha ebonelelwe yibhokisi yovavanyo lwamandla kunye nerakhi yovavanyo lokuguga, ukuqonda okubanzi kokusebenza kwezibane ze-LED ngexesha lenkqubo yokuguga kunokufumaneka. Ukunika ingqalelo kwiimpawu eziphambili ezifana nobushushu besibane, i-voltage yokuphuma, i-power factor, i-voltage yokufaka, i-input current, ukusetyenziswa kwamandla, kunye ne-output current kunokunceda ekumiseleni isantya sokuguga kunye nokuzinza kokusebenza kwezibane ze-LED, ukuze kuthathwe amanyathelo okugcina afanelekileyo ukuqinisekisa ukusetyenziswa kwexesha elide nokuthembekileyo kwezibane ze-LED.
