Sezvo awholesale led light supplier,Eurborn ane yakekunze fekitariuyemold department, inyanzvi mukugadzirazviedza zvekunze, uye anoziva yese parameter yechigadzirwa zvakanaka. Nhasi, ini ndichagovana newe nzira yekusiyanisa pakati penguva dzose voltage uye inogara iripo ye LED drive simba.
1. Nguva dzose magetsi emagetsi zvinoreva kuti ikozvino inoyerera nemutoro inoramba isina kuchinja kana magetsi achinja. Constant voltage power supply zvinoreva kuti magetsi emagetsi haashanduke kana yazvino ichiyerera nepamutoro ichichinja.
2. Izvo zvinonzi zvinogara zviripo / zvinogara zvichiitika zvinoreva kuti kubuda kwezvino / voltage kunoramba kuripo mukati meimwe nzvimbo. Chirevo che "constant" chiri mukati meimwe nhanho. Kune "constant current", voltage inobuda inofanira kunge iri mukati meimwe nhanho, uye ye "constant voltage", inobuda ikozvino inofanira kunge iri mukati meimwe nhanho. Kupfuura renji iyi "constant" haigone kuchengetedzwa. Naizvozvo, iyo inogara voltage sosi inoisa ma parameter eiyo inobuda faira (yakanyanya kuburitsa). Kutaura zvazviri, hapana chinhu chakadai se "nguva dzose" munyika yemagetsi. Zvose zvemagetsi zvine chiratidzo chekugadzirisa mutoro. Tora iyo inogara voltage (voltage) sosi semuenzaniso: sezvo mutoro wako uchiwedzera, iyo inobuda voltage inofanira kudonha.
3. Musiyano uripo pakati penguva dzose voltage sosi uye inogara iripo ikozvino sosi mukutsanangura:
1) Pasi pemamiriro emutoro unobvumidzwa, iyo inobuda voltage yeanogara voltage sosi inogara uye haishanduke nekuchinja kwemutoro. Kazhinji inoshandiswa mune yakaderera-simba LED modules, uye yakaderera-simba LED mitsetse inowanzoshandiswa. Iyo inogara iripo voltage sosi ndiyo yatinowanzo kudaidza kuti yakadzorwa magetsi, ayo anogona kuve nechokwadi chekuti voltage inoramba isina kuchinjika kana mutoro (output current) wachinja.
2) Pasi pemamiriro emutoro unotenderwa, iyo inobuda ikozvino yeanogara iripo sosi inongogara uye haishanduke nekuchinja kwemutoro. Inowanzoshandiswa mu-high-power LEDs uye high-end low-power products. Kana iyo bvunzo yakanaka maererano nehupenyu, iyo inogara iripo ikozvino sosi LED mutyairi ari nani.
Iyo inogara iripo ikozvino sosi inogona kugadzirisa yayo yekubuda voltage zvinoenderana kana mutoro uchichinja, kuitira kuti inobuda ikozvino irambe isingachinji. Iwo magetsi ekuchinja magetsi atakaona ndiwo anogara ari magetsi emagetsi, uye iyo inonzi "inogara iripo ikozvino switching magetsi" yakavakirwa pane inogara voltage sosi, uye diki yekupikisa sampling resistor inowedzerwa kune inobuda. Iyo yekumberi nhanho inoenda kutonga kune inogara iripo ikozvino kutonga.
4. Nzira yekuziva sei kuti inogara iri voltage sosi kana kuti inogara iripo kubva kune magetsi emagetsi parameters?
Inogona kuoneka kubva kune iyo label yemagetsi ekupa: kana iyo inobuda voltage yainozivisa kukosha kwekugara (senge
Vo = 48V), inogara iri voltage sosi: kana ikaratidza huwandu hwemagetsi (semuenzaniso, Vo iri 45 ~ 90V), inogona kutariswa kuti iyi inogara iripo ikozvino sosi.
5. Zvakanakira uye zvakaipira zvenguva dzose voltage sosi uye inogara iripo ikozvino sosi: inongogara voltage sosi inogona kupa inogara voltage yemutoro, yakanaka inogara voltage sosi.
Iko kupikisa kwemukati ndeye zero uye haigone kupfupika-inotenderera. Iyo inogara iripo yazvino sosi inogona kupa inogara iripo kumutoro, uye yakaringana yazvino sosi ine kusingaperi yemukati kuramba yakakura, haigone kuvhura nzira.
6. LED inhengo yemagetsi inoshanda neanogara aripo (voltage yekushanda inenge yakagadziriswa, uye zvishoma zvishoma zvayo zvichakonzera kuchinja kukuru mune ikozvino). Chete nekushandisa iyo inogara iripo nzira inogona kupenya kunoenderana uye hupenyu hurefu hunovimbiswa zvechokwadi. Kana iyo inogara ichityaira yemagetsi magetsi iri kushanda, zvinodikanwa kuti uwedzere yazvino module kana yazvino yekumisikidza resistor kune mwenje, nepo inogara iripo yekutyaira magetsi inongove inogara yazvino module yeiyo inogara voltage sosi yakavakirwa-mukati.
Isu tiriMugadziri wemwenje we LED, Chikwata chedu cheR&D chine makore anopfuura makumi maviri ekunze kwekuvaka mwenje ruzivo. Tichipindura kune zvinodiwa nevatengi vedu, isu tinokurumidza uye zvinobudirira kupedza ODM, OEM dhizaini, uye tinopa rubatsiro rwehunyanzvi rwehunyanzvi kuti rienderane netarisiro.Tinogamuchira kubvunza kwako chero nguva!
