Mushure memakore ebudiriro, yechinyakare yakajairika anode LED kuratidza yakagadzira yakagadzika maindasitiri cheni, izvo zvakakonzera kufarirwa kwe LED kuratidzwa.Nekudaro, iyo zvakare ine zvipingamupinyi, yakawandisa skrini tembiricha uye yakawandisa simba mashandisiro.Mushure mekuonekwa kweyakajairwa cathode LED kuratidza simba tekinoroji, yakwezva kutarisisa kukuru mumusika wekuratidzira we LED.Iyi nzira yekugovera magetsi inogona kuwana yakanyanya kuchengetedza simba re75%, saka chii chinonzi magetsi tekinoroji yeyakajairwa cathode LED kuratidza?Ndezvipi zvakanakira tekinoroji iyi?
Ndeapi mabhenefiti emagetsi ekupa tekinoroji yeyakajairwa cathode LED kuratidza
1. Chii chinonzi cathode LED kuratidza?
"Common cathode" inoreva nzira yakajairwa yemagetsi emagetsi.Muchokwadi, iyi tekinoroji inochengetedza simba yezviratidziro zve LED.Zvinoreva kushandisa yakajairwa cathode kugonesa chiratidziro che LED.B (tsvuku, girini, bhuruu) inoparadzanisa magetsi, uye nekunyatso kugovera ikozvino uye voltage yeR, G, B marambi mabheji, nekuti iyo R, G, B (tsvuku, girinhi, bhuruu) marambi mabhero anoda kushanda zvakanyanya. voltage, uye ikozvino yakasiyana, Nokudaro, ikozvino inotanga kupfuura nemucheka wemwenje, uye inosvika padanda rakashata re IC, kuderedza kudonha kwemhepo kumberi uye kuderedza conduction yemukati kuramba.
2. Ndeupi musiyano uripo pakati pe common cathode uye common anode LED inoratidza?
①.Nzira dzakasiyana dzekupa magetsi:
Iyo inowanzoshandiswa cathode magetsi emagetsi nzira ndeyokuti ikozvino inotanga kupfuura nepakati pemwenje bhedhi uye inosvika padanda rakashata redunhu rakasanganiswa, kuitira kuti kudonha kwemhepo kumberi kuve kudiki uye kupikisa kunova kudiki.
Iyo inowanzoitika inode ndiyo inoyerera kubva kuPCB board kuenda kune mwenje mabheji, uye zvakaenzana inopa simba kuR, G, B (tsvuku, girini, bhuruu), kuitira kuti kudonha kwemagetsi kumberi kwedunhu kuve kwakakura.
②.Iyo magetsi emagetsi akasiyana:
Yakajairika cathode, inopa ikozvino uye voltage yeR, G, B (tsvuku, girini, bhuruu), zvichiteerana.Tsvuku, girini uye bhuruu maLED ane akasiyana voltage zvinodiwa.Iwo magetsi emarambi matsvuku angangoita 2.8V, uye voltage yebhuruu uye girini marambi mabhero anenge 3.8V, iyi magetsi inogona kuwana chaiyo magetsi uye magetsi.Nekuda kwekurasikirwa kudiki, kupisa kunogadzirwa ne LED kuratidzwa panguva yekushanda kwakaderera zvakanyanya.
Iyo cathode yakajairika inoda kupa R, G, B (tsvuku, girini, bhuruu) simba rakabatana rinopfuura 3.8V (se5V).Panguva ino, magetsi anowanikwa nehutsvuku, girini uye bhuruu yunifomu 5V, nepo tsvuku, girini, The optimal working voltage inodiwa nematatu eblue mabeads akadzikira kupfuura 5V.Zvinoenderana neformula yesimba P = UI, pasi pemamiriro anogara aripo, iyo yakakwira voltage, iyo yakakura simba, ndiko kuti, iyo yakakura mashandisiro emagetsi, nepo LED inoratidzira iri kushanda Kupisa kwakawanda kunogadzirwa mukuita.
3. Nei kupisa kweyakajairwa cathode LED kuratidza kwakaderera?
Iyo yakakosha yakajairwa cathode magetsi emagetsi modhi yeinotonhora skrini inoita kuti iyo LED yekuratidzira maitiro igadzire kushoma kupisa uye kuderera kwekushisa kukwira.Mumamiriro ezvinhu akajairwa, panguva chena chiyero uye kutamba kwevhidhiyo, tembiricha yeinotonhora skrini ingangoita 20 ° C yakaderera pane iyo yechinyakare kunze kwe LED kuratidzwa kwemuenzaniso wakafanana.Pasi pezvakatemerwa zvakafanana uye kupenya kwakafanana, tembiricha yeyakajairwa cathode LED inoratidzira inodarika 20 madhigirii yakaderera pane iyo yakajairwa anode LED kuratidza zvigadzirwa, uye mashandisirwo emagetsi ari 50% akaderera pane ayo akajairwa anode LED kuratidza zvigadzirwa.
Kupisa kwakanyanya kweiyo LED kuratidza skrini uye yakawandisa mashandisiro emagetsi zvagara zviri zvinhu zvakakosha zvinokanganisa hupenyu hwesevhisi yeLED kuratidza skrini."Common cathode LED kuratidza" inogona kugadzirisa matambudziko maviri aya.
4. Ndezvipi zvakanakira zvakajairika cathode LED kuratidza?
magetsi emagetsi anonyatso chengetedza simba:
Zvakajairwa cathode zvigadzirwa zvinotora chaiyo simba rekudzora tekinoroji, zvinoenderana neakasiyana optoelectronic hunhu hwemavara matatu ekutanga e LED tsvuku, girinhi uye bhuruu, yakasanganiswa nehungwaru IC kuratidza control system uye yakazvimirira yakazvitsaurira modhi, iwo akasiyana voltages eLED uye dhiraivha yekutyaira ndeyechokwadi. yakagoverwa, kuitira kuti simba rekushandisa rechigadzirwa rive rakakwirira.Zvigadzirwa zvakafanana mumusika chengetedza nezve 40%!
②.Kuchengetedza simba chaiko kunounza ruvara chairwo:
Iyo inowanzoshandiswa cathode LED yekutyaira nzira inogona kunyatso kudzora magetsi, uku ichideredza kushandiswa kwesimba uye kupisa kugadzirwa, wavelength ye LED haizonyungudika panguva yekuenderera mberi kwekushanda, uye ruvara rwechokwadi runogona kuratidzwa zvakatsiga!
③.Kuchengetedza simba chaiko kunounza hupenyu hurefu:
Iko kushandiswa kwesimba kunoderedzwa, kukwira kwekushisa kwegadziriro kunodzikiswa zvakanyanya, mukana wekukuvara kwe LED unonyatso kuderedzwa, kugadzikana uye kuvimbika kweiyo yese yekuratidzira system inovandudzwa, uye hupenyu hwesevhisi hwehurongwa hwakawedzerwa zvakanyanya.
5. Ndeapi maitiro mune akajairika tekinoroji asina kunaka?
Inoenderana neyakajairwa cathode LED kuratidza tekinoroji senge maLED, magetsi ekushandisa, uye mutyairi ICs, haina kukura seRam LED indasitiri chain.Mukuwedzera, iyo yazvino yakajairika cathode IC yakatevedzana haina kukwana, uye iyo yakazara yekutengesa vhoriyamu haina kukura.Ram ichiri kutora 80% yemusika.
Chikonzero chikuru chekuvandudza kunonoka kweakajairwa cathode tekinoroji parizvino mutengo wepamusoro wekugadzira.Pahwaro hwekubatana kwekutanga kugovera ketani, iyo yakajairwa cathode inoda yakagadziridzwa kubatirana kumagumo eindustry cheni senge machipisi, kurongedza, uye maPCB, uye mutengo wakakwira.
Munguva ino yekunyanya kudiwa kwekuchengetedza simba, kubuda kweiyo yakajairika yakashata yakajeka LED kuratidzwa kwave nzvimbo yekutsigira yeiyi indasitiri yekutsvaga.Nekudaro, kuchine nzira refu yekuenda kuzadzisa kukwidziridzwa kwakazara uye kushandiswa mune yakakura pfungwa, uye kuedza kwakabatana kweindasitiri yese kunodiwa.Ordinary cathode LED kuratidza inosanganisira kushandiswa kwesimba remagetsi uye mari yekushandisa, inova maitiro ekuvandudza ekuchengetedza simba.Nokudaro, kuchengetedza simba uye kuderedza kushandiswa kwakabatana nezvido zvevaratidziri ve LED uye kushandiswa kwesimba renyika.
Tichitarisa kubva pamamiriro ezvinhu aripo, iyo yakajairwa cathode LED inochengetedza simba kuratidza haizowedzera mutengo wakawandisa kana ichienzaniswa neyakajairwa kuratidzwa, uye zvakare ichachengetedza mari mukushandiswa kweramangwana, iyo inogamuchirwa zvakanaka nemusika.
