LED yakakurumidza kukura muzvikamu zvakasiyana-siyana zvekushandisa mumakore achangopfuura, nokuti haina zvinhu zvine chepfu, inoshamwaridzana nenharaunda, ine hupenyu hurefu hwebasa, uye ine high optical kunyatsoshanda.Muchiono, hupenyu hwebasa re LED hunenge maawa e100,000, asi mukushanda kwese kwekushanda, vamwe vagadziri veLELED mwenje havazivi zvakakwana nezve LED yekufambisa kushandura magetsi kana kuishandisa zvisina musoro, uye mhedziso inopfupisa zvikuru hupenyu hwebasa remwenje we LED. zvigadzirwa.
Nekuda kwekusiyana kwekugadzirwa kwe LED, kugadzirisa uye kugadzirwa, ikozvino uye inoshanda voltage maitiro e LED anogadzirwa nevagadziri vakasiyana uye kunyangwe mugadziri mumwechete mubatch rimwe chete rezvigadzirwa ane misiyano mikuru yega yega.Tichitora yakajairwa 1W chena mwenje LED maratidziro uye modhi semuenzaniso, zvinoenderana nekuchinja kwe LED ikozvino uye kushanda voltage, inotsanangurwa muchidimbu kuti 1W chena mwenje kazhinji inotora yakanaka inoshanda voltage inosvika 3.0-3.6V.Kuti uve nechokwadi chehupenyu hwesevhisi ye1WLED, iyo general inogadzira LED inokurudzira kuti fekitori yekuvhenekesa ishandise ikozvino ye350mA kutyaira.Kana iyo yekumberi kumativi ese e LED yasvika 350mah, iyo yekumberi inoshanda magetsi pamativi ese e LED haizowedzera zvakanyanya, izvo zvichawedzera zvakanyanya kumberi kweiyo LED kuwedzera ma bulbs e LED, zvichiita kuti tembiricha ye LED ipinde mukati. mutsara wakafanana, nekudaro uchimhanyisa mwenje we LED.kukanganisa, kuderedza hupenyu hwebasa re LED.Nekuda kwekusiyana kweiyo LED's yekushanda voltage uye ikozvino shanduko, iyo switching magetsi inotyaira maLED inotariswa zvakanyanya.
LED drive switching power supply ndiyo hwaro hwemarambi e LED.Zvakafanana neuropi hwemunhu.Kugadzira mwenje wemhando yepamusoro e LED, iyo inogara-voltage nzira yekutyaira ma LED inofanira kusiiwa.
Panguva ino, kune zvigadzirwa zvemwenje zve LED zvinogadzirwa nevazhinji vagadziri (senge fenzi yekudzivirira, makapu emwenje, mwenje wekuratidzira, mwenje welawn, nezvimwewo), sarudza zvinopikisa, kuderedza kukwira kweropa, uye wobva wawedzera Zener diode Zener chubhu kusimba reLED. hurongwa hwekugovera, kuitira kusimudzira maLED's Nzira ine zvipingamupinyi zvakakura, chekutanga, haina kukwana, inoshandisa yakawanda yemagetsi emagetsi pane inotsika-pasi resistor, uye inogona kutopfuura simba remagetsi rinopedzwa ne LED, uye haigone. fambisa mafungu makuru.Nekuti iyo yakakwira ikozvino, iyo yakawanda simba inoraswa pane nhanho-pasi resistor, hapana vimbiso yekuti iyo LED ikozvino haizopfuure yayo yakajairika inoshanda mwero.Paunenge uchigadzira chigadzirwa, kusarudza kudzikisa maviri maDC voltages e LED kutyaira iyo magetsi emagetsi system ndiyo yakakura mukana wekusiya iyo LED chromaticity.Sarudza kupikisa, iyo nzira yekudzikisa BP kusunda iyo LED, iyo skrini inopenya ye LED haigone kugadzikana.Kana magetsi emagetsi emagetsi emagetsi emagetsi akadzikira, chromaticity ye LED yakasviba, uye kana magetsi emagetsi emagetsi emagetsi emagetsi akakwira, chromaticity ye LED yakakwira, uye chromaticity ye LED iri pamusoro. high.Nomuzvarirwo, nzira yekudzikisa BP ndiyo yakanakira kudzikisa mutengo.
