Njengeumthengisi we-led light,U-Eurborn uneyakheumzi-mveliso wangaphandlekwayeisebe lokungunda, iyingcali kwimvelisoizibane zangaphandle, kwaye uyazi yonke ipharamitha yemveliso kakuhle. Namhlanje, ndiza kubelana nawe ngendlela yokwahlula phakathi kombane ongaguqukiyo kunye nokuqhubekayo kwamandla e-LED drive.
1. Unikezelo lwamandla lwangoku lwangoku luthetha ukuba umbane ojikelezayo ngomthwalo uhlala ungatshintshi xa umbane utshintsha. Unikezelo lwamandla ombane rhoqo luthetha ukuba umbane wombane awutshintshi xa umbane oqukuqelayo utshintsha.
2. Okubizwa ngokuba yi-voltage eqhubekayo / eqhubekayo ithetha ukuba i-output current / voltage ihlala ihleli ngaphakathi kwinqanaba elithile. Isiseko se "constant" singaphakathi koluhlu oluthile. Kwi-"current current", i-voltage ephumayo kufuneka ibe phakathi koluhlu oluthile, kwaye "kwi-voltage eqhubekayo", i-voltage yangoku kufuneka ibe phakathi koluhlu oluthile. Ngaphaya kolu luhlu "constant" ayinakugcinwa. Ngoko ke, umthombo we-voltage rhoqo uya kuseka iiparameters zefayile yangoku yokuphuma (ubuninzi bemveliso). Ngapha koko, akukho nto ibizwa ngokuba "ngatshintshiyo" kwihlabathi le-elektroniki. Zonke izixhobo zombane zinesalathisi solawulo lomthwalo. Thatha umthombo wombane ongaguqukiyo (i-voltage) njengomzekelo: njengoko umthwalo wakho usanda, i-voltage ephumayo kufuneka yehle.
3. Umahluko phakathi komthombo wombane ongaguqukiyo kunye nomthombo wangoku oqhubekayo kwinkcazo:
1) Ngaphantsi kwemeko yomthwalo ovumelekileyo, i-voltage ephumayo yomthombo we-voltage eqhubekayo ihlala kwaye ayiyi kutshintsha ngokutshintsha komthwalo. Ngokuqhelekileyo isetyenziswe kwiimodyuli ze-LED eziphantsi kwamandla, kunye nemichilo ye-LED ephantsi isetyenziswa rhoqo. Umthombo wamandla ombane oqhubekayo yinto esihlala siyibiza ngokuba ngumbane olawulwayo, onokuqinisekisa ukuba i-voltage ihlala ingatshintshi xa umthwalo (i-output current) itshintsha.
2) Ngaphantsi kwemeko yomthwalo ovumelekileyo, umbane ophumayo womthombo wangoku uhlala uhleli kwaye awuyi kutshintsha ngokutshintsha komthwalo. Ngokuqhelekileyo isetyenziswe kwii-LED eziphezulu kunye neemveliso zamandla aphantsi. Ukuba uvavanyo lulungile ngokwemigaqo yobomi, umthombo oqhubekayo we-LED umqhubi ungcono.
Umthombo oqhubekayo wangoku unokulungelelanisa i-voltage yayo yokuphuma ngokufanelekileyo xa umthwalo uguquka, ukwenzela ukuba imveliso yangoku ihlale ingatshintshi. Amandla okutshintsha esiwabonileyo ayimithombo yombane rhoqo, kwaye oko kubizwa ngokuba "unikezelo lwamandla okutshintsha rhoqo" lusekwe kumthombo wombane ongaguqukiyo, kunye nesampulu yokumelana nesampulu encinci yongezwa kwimveliso. Inqanaba langaphambili liya kulawulo lolawulo lwangoku oluqhubekayo.
4. Indlela yokuchonga ukuba ingaba ngumthombo we-voltage oqhubekayo okanye umthombo okhoyo oqhubekayo ovela kwiiparamitha zombane?
Inokubonwa kwileyibhile yonikezelo lwamandla: ukuba i-voltage yemveliso ichaza ixabiso elingaguqukiyo (elifana ne
I-Vo = 48V), ngumthombo we-voltage rhoqo: ukuba ichonga uluhlu lwe-voltage (umzekelo, i-Vo yi-45 ~ 90V), inokumiselwa ukuba lo ngumthombo okhoyo ngoku.
5. Izinto eziluncedo kunye nezingeloncedo zomthombo wamandla ombane oqhubekayo kunye nomthombo wangoku oqhubekayo: umthombo wamandla ombane ongaguqukiyo unokubonelela ngevoltheji engaguqukiyo yomthwalo, eyona mthombo wombane ongaguqukiyo.
Ukuchasana kwangaphakathi ngu-zero kwaye akukwazi ukujikeleza ngokukhawuleza. Umthombo wangoku ongaguqukiyo unokubonelela ngokuqhubekayo kumthwalo, kwaye umthombo oqhelekileyo oqhubekayo unokumelana okungapheliyo kwangaphakathi okukhulu, awukwazi ukuvula indlela.
6. I-LED iyingxenye ye-elektroniki esebenza ngokuqhubekayo (i-voltage esebenzayo igxininisekile, kwaye i-offset encinci iya kubangela utshintsho olukhulu lwangoku). Kuphela ngokusebenzisa indlela eqhubekayo yangoku apho ukukhanya okuhambelanayo kunye nobomi obude buqinisekisiwe ngokwenene. Xa unikezelo lwamandla ombane oqhuba rhoqo lusebenza, kuyafuneka ukongeza imodyuli eqhubekayo yangoku okanye isichasi somda sangoku kwisibane, ngelixa umbane oqhubayo wangoku unemodyuli yangoku yomthombo wamandla ombane owakhelwe ngaphakathi.
Siyi-Umenzi wezibane ze-LED, Iqela lethu le-R&D lineminyaka engaphezu kwama-20 yamava okukhanyisa angaphandle. Ukuphendula kwiimfuno zabathengi bethu, sigqibezela ngokukhawuleza nangempumelelo i-ODM, uyilo lwe-OEM, kwaye sibonelela ngenkxaso yobuchwephesha obuchwepheshile ukuhambelana nokulindelweyo.Samkela isicelo sakho nangaliphi na ixesha!
