Ungahlukanisa kanjani phakathi kwe-voltage engaguquki kanye namandla angashintshi we-LED drive power supply?

Njengoumphakeli we-wholesale led light,U-Eurborn unomnikaziimboni yangaphandlefuthiumnyango isikhunta, iwuchwepheshe kwezokukhiqizaizibani zangaphandle, futhi wazi yonke ipharamitha yomkhiqizo kahle. Namuhla, ngizokwabelana nawe ukuthi ungahlukanisa kanjani phakathi kwe-voltage engaguquki kanye namandla angashintshi wedrayivu ye-LED.

1. Ukunikezwa kwamandla wamanje njalo kusho ukuthi i-current egeleza phakathi komthwalo ihlala ingashintshile lapho ukunikezwa kwamandla kushintsha. Ukunikezwa kwamandla kagesi okungaguquki kusho ukuthi i-voltage yokuphakela amandla ayishintshi lapho i-current egeleza phakathi komthwalo ishintsha.

2. Okubizwa ngokuthi i-voltage eqhubekayo yamanje/ehlala njalo kusho ukuthi i-current/voltage ephumayo ihlala ingashintshi phakathi kwebanga elithile. Isisekelo sokuthi "njalo" singaphakathi kwebanga elithile. Ku-"current current", i-voltage ephumayo kufanele ibe phakathi kwebanga elithile, futhi "ku-voltage eqhubekayo", i-voltage ephumayo kufanele ibe phakathi kwebanga elithile. Ngale kwalolu bubanzi "okuqhubekayo" akunakugcinwa. Ngakho-ke, umthombo we-voltage ongaguquki uzosetha imingcele yefayela lamanje lokuphumayo (okuphumayo okuphezulu). Eqinisweni, ayikho into ebizwa ngokuthi "ihlala njalo" emhlabeni we-elekthronikhi. Zonke izinsiza zikagesi zinenkomba yokulawulwa komthwalo. Thatha umthombo we-voltage (voltage) ongashintshi njengesibonelo: njengoba umthwalo wakho ukhula, i-voltage ephumayo kufanele yehle.

3. Umehluko phakathi komthombo wamandla kagesi ongashintshi kanye nomthombo wamanje ongashintshi ekuchazeni:

I-1) Ngaphansi kwesimo somthwalo ovunyelwe, i-voltage ephumayo yomthombo we-voltage engashintshi ihlala njalo futhi ngeke ishintshe ngokushintsha komthwalo. Imvamisa isetshenziswa kumamojula we-LED anamandla aphansi, futhi imichilo ye-LED enamandla aphansi ivame ukusetshenziswa. Umthombo wamandla kagesi ongaguquki yilokho esivame ukukubiza ngokuthi ukunikezwa kwamandla okulawulwayo, okungaqinisekisa ukuthi i-voltage ihlala ingashintshile lapho umthwalo (output current) ushintsha.

I-2) Ngaphansi kwesimo somthwalo ovunyelwe, ukukhishwa kwamanje komthombo wamanje oqhubekayo kuhlala njalo futhi ngeke kushintshe ngokushintsha komthwalo. Ivamise ukusetshenziswa kuma-LED aphezulu kanye nemikhiqizo yamandla aphansi aphezulu. Uma ukuhlolwa kuhle ngokwempilo, umshayeli we-LED oqhubekayo wamanje ungcono.

Umthombo wamanje oqhubekayo ungalungisa i-voltage yayo yokuphuma ngokufanele lapho umthwalo ushintsha, ukuze ukukhishwa kwamanje kuhlale kungashintshiwe. Izinto zamandla ezishintshayo esizibonile ziyimithombo yamandla kagesi engaguquki, futhi lokho okubizwa ngokuthi "ukunikezwa kwamandla okushintshashintsha kwamanje" kusekelwe kumthombo we-voltage ongashintshi, futhi isampula encane yokumelana nesampula yengezwe ekuphumeni. Isiteji esingaphambili siyalawula ukuze silawule okwamanje.

4. Ungabona kanjani ukuthi ungumthombo we-voltage ongashintshi noma umthombo wamanje oqhubekayo ovela kumingcele yokuphakelwa kwamandla?

Ingabonwa kulebula yomthombo wamandla: uma i-voltage ephumayo ihlonza inani elingaguquki (njengokuthi
I-Vo=48V), ingumthombo wamandla kagesi ongashintshi: uma ikhomba ububanzi be-voltage (isibonelo, i-Vo ingu-45~90V), kunganqunywa ukuthi lona ungumthombo wamanje ongashintshi.

5. Izinzuzo kanye nobubi bomthombo wamandla kagesi ongashintshi kanye nomthombo wamanje ongashintshi: umthombo wamandla kagesi ongaguquki unganikeza i-voltage engaguquki yokulayisha, umthombo wamandla kagesi ongaguquki.

Ukumelana kwangaphakathi kunguziro futhi akukwazi ukufinyezwa. Umthombo wamanje ongaguquki unganikeza amandla angashintshi emthwalweni, futhi umthombo wamanje olungile unokumelana okungapheli okukhulu, awukwazi ukuvula indlela.

6. I-LED iyingxenye ye-elekthronikhi esebenza ngokuqhubekayo (i-voltage yokusebenza ilinganiselwe, futhi i-offset encane yayo izobangela ushintsho olukhulu lwamanje). Ngokusebenzisa indlela yamanje kuphela lapho ukukhanya okungaguquki nempilo ende kungaqinisekiswa ngempela. Lapho amandla okushayela kagesi ahlala esebenza, kuyadingeka ukwengeza imojula yamanje engashintshi noma isixhasi esinciphisa umkhawulo esibani, kuyilapho amandla amanje okushayela angashintshi anemojula yamanje engaguquki yomthombo wamandla kagesi owakhelwe ngaphakathi.

Siyi-Umkhiqizi wezibani ze-LED, Ithimba lethu le-R&D lineminyaka engaphezu kuka-20 yokuhlangenwe nakho kokukhanyisa kwezakhiwo zangaphandle. Siphendula izidingo zamakhasimende ethu, siqeda ngokushesha nangempumelelo i-ODM, umklamo we-OEM, futhi sinikeza ukusekelwa kobuchwepheshe okuchwepheshile ukuze kufane nokulindelwe.Samukela uphenyo lwakho nganoma yisiphi isikhathi!
