Mushure memakore ebudiriro, yakajairwa anode LED yakagadzira yakagadzikana indasitiri ketani, ichityaira mukurumbira we LED kuratidza. Nekudaro, iyo zvakare ine zvakaipira zveyakakwira skrini tembiricha uye yakawandisa simba rekushandisa. Mushure mekubuda kweyakajairwa cathode LED kuratidza magetsi ekupa tekinoroji, yakwezva kutarisisa kukuru mumusika wekuratidzira we LED. Iyi nzira yekugovera magetsi inogona kuwana yakanyanya kuchengetedza simba re75%. Saka chii chakajairika cathode LED kuratidza magetsi emagetsi tekinoroji? Ndezvipi zvakanakira tekinoroji iyi?
1. Chii chinowanzoitika cathode LED?
"Common cathode" inoreva nzira yakajairwa yemagetsi cathode, inova tekinoroji inochengetedza simba ye LED kuratidza skrini. Zvinoreva kushandisa yakajairwa cathode nzira yekusimbisa iyo LED kuratidza skrini, kureva, iyo R, G, B (tsvuku, girini, bhuruu) yemwenje ye LED mabeheru anofambiswa zvakasiyana, uye yazvino uye voltage zvakagoverwa nenzira kwayo kuR. , G, B mwenje mabheji zvichiteerana, nekuti iyo yakakwana yekushanda voltage uye ikozvino inodiwa neR, G, B (tsvuku, girini, bhuruu) marambi mabheji akasiyana. Nenzira iyi, ikozvino yekutanga inopfuura nepakati pemarambi uye ipapo kune yakaipa electrode yeIC, kudonha kwemhepo kumberi kuchaderedzwa, uye kupikisa kwemukati kuchava kuduku.
2. Ndeupi musiyano uripo pakati pe common cathode uye common anode LEDs?
①. Nzira dzakasiyana dzekupa magetsi:
Iyo yakajairika cathode magetsi emagetsi nzira ndeyekuti ikozvino yekutanga inopfuura nepakati mwenje bhedhi uyezve kune yakaipa danda reIC, iyo inoderedza kudonha kwemagetsi kumberi uye conduction yemukati kuramba.
Anode yakajairika ndeyokuti ikozvino inoyerera ichibva kuPCB bhodhi kuenda kubhedhi remwenje, uye inopa simba kuR, G, B (tsvuku, girini, bhuruu) zvakafanana, izvo zvinotungamira kune yakakura kuderera kwemagetsi kudonha mudunhu.
②. Kusiyana kwemagetsi emagetsi:
Common cathode, ichapa ikozvino uye voltage kune R, G, B (tsvuku, girini, bhuruu) zvakasiyana. Izvo zvinodikanwa zvevoltage tsvuku, girini uye bhuruu mwenje marambi akasiyana. Iyo voltage inodiwa yemarambi matsvuku ingangoita 2.8V, uye voltage inodiwa yeblue-girini marambi mabhero ingangoita 3.8V. Simba rakadaro rinogona kuwana simba rakarurama uye kushandiswa kwesimba shoma, uye kupisa kunogadzirwa ne LED panguva yebasa kwakaderera zvikuru.
Common anode, kune rumwe rutivi, inopa R, G, B (tsvuku, girini, bhuruu) voltage yakakwira kupfuura 3.8V (senge 5V) yemagetsi akabatana. Panguva ino, magetsi anowanikwa nehutsvuku, girini uye bhuruu ndeye 5V yakabatana, asi iyo yakakwana yekushanda voltage inodiwa nemarambi matatu mabhero akadzikira zvakanyanya kupfuura 5V. Zvinoenderana neformula yesimba P = UI, kana ikozvino ikaramba isina kuchinjika, iyo yakakwira voltage, iyo yakakwirira simba, ndiko kuti, iyo yakakura kushandisa simba. Panguva imwecheteyo, iyo LED inoburitsawo kupisa kwakawanda panguva yebasa.
TheGlobal Third-Generation Outdoor LED Advertising Screen Yakagadzirwa neXYGLED, inotora common cathode. Zvichienzaniswa neyakajairwa 5V tsvuku, girinhi, uye yebhuruu light-emitting diodes, danda rakanaka reiyo dzvuku LED chip i3.2V, nepo girinhi nebhuruu maLED ari 4.2V, kuderedza kushandiswa kwesimba neinenge 30% uye kuratidza yakanakisa simba- kuchengetedza uye kushandiswa-kuderedza kushanda.
3. Sei yakajairika cathode LED kuratidza kuburitsa kushoma kupisa?
Iyo yakakosha yakajairika cathode magetsi emagetsi modhi yeinotonhora skrini inoita kuti LED iratidziro ibudise kupisa kushoma uye kuderera kwekushisa kukwira panguva yekushanda. Mumamiriro ezvinhu akajairwa, mune chena chiyero mamiriro uye kana uchitamba mavhidhiyo, tembiricha yeinotonhora skrini ingangoita 20 ℃ yakaderera pane iyo yakajairwa yekunze yekunze kuratidzwa kwe LED yemhando imwe chete. Kune zvigadzirwa zvezvakangofanana uye nekupenya kwakafanana, tembiricha yeyakajairwa cathode LED inoratidzira inodarika 20 madhigirii yakaderera pane iyo yakajairika anode LED kuratidza zvigadzirwa, uye mashandisiro emagetsi anodarika makumi mashanu muzana pasi peiyo. yezvakajairika anode LED kuratidza zvigadzirwa.
Iyo yakanyanya tembiricha uye mashandisiro emagetsi echiratidziro che LED zvagara zviri izvo zvakakosha zvinokanganisa hupenyu hwesevhisi yezvigadzirwa zve LED, uye "yakajairwa cathode LED kuratidza" inogona kugadzirisa matambudziko maviri aya zvakanaka.
4. Ndezvipi zvakanakira zvakajairika cathode LED kuratidza?
①. Magetsi chaiwo anochengetedza simba:
Iyo yakajairwa cathode chigadzirwa inotora chaiyo magetsi ekutonga tekinoroji, zvichibva pane akasiyana mafotoelectric maitiro emhando nhatu dzekutanga dzeLED tsvuku, girinhi uye bhuruu, uye yakashongedzerwa nehungwaru IC kuratidza control system uye yakazvimiririra yakavanzika mold yekugovera nenzira kwayo ma voltages akasiyana. ku LED uye dhiraivha yedhiraivha, kuitira kuti chigadzirwa chemagetsi chinoshandiswa chinenge 40% yakaderera pane yezvigadzirwa zvakafanana pamusika!
②. Kuchengetedza simba kwechokwadi kunounza mavara echokwadi:
Iyo yakajairika cathode LED yekutyaira nzira inogona kunyatso kudzora voltage, iyo inoderedza kushandiswa kwesimba uye kupisa chizvarwa. Iyo wavelength yeLED haifambi pasi pekuenderera kwekushanda, uye iyo yechokwadi ruvara inoratidzwa zvakatsiga!
③. Chokwadi kuchengetedza simba kunounza hupenyu hurefu:
Iko kushandiswa kwesimba kunoderedzwa, nekudaro kudzikisa zvakanyanya kukwira kwekushisa kwehurongwa, zvichinyatso kudzikisa mukana wekukuvara kwe LED, kuvandudza kugadzikana uye kuvimbika kweiyo yese system yekuratidzira, uye nekuwedzera zvakanyanya hupenyu hwehurongwa.
5. Ndeipi nzira yekusimudzira ye common cathode tekinoroji?
Zvigadzirwa zvinotsigira zvine chekuita neyakajairwa cathode LED kuratidza tekinoroji, senge LED, magetsi, mutyairi IC, nezvimwewo, hazvina kukura seyakajairwa anode LED indasitiri chain. Uye zvakare, iyo yakajairwa cathode IC yakatevedzana haina kukwana parizvino, uye huwandu hwese hahuna hombe, nepo anode yakajairika ichiri kutora makumi masere muzana emusika.
Chikonzero chikuru chekufambira mberi zvishoma nezvishoma kweiyo yakajairika cathode tekinoroji mutengo wekugadzira wakakwira. Zvichienderana nekutanga kugovera ketani yekudyidzana, yakajairika cathode inoda yakagadziridzwa kubatirana kumativi ese eindastiri ketani senge machipisi, kurongedza, PCB, nezvimwe, izvo zvinodhura.
Munguva ino yekufona kwakakwira kwekuchengetedza simba, kubuda kweyakajairika cathode transparent LED kuratidza skrini kwave nzvimbo yekutsigira inoteverwa neindasitiri iyi. Nekudaro, kuchine nzira refu yekuenda kuti uwane kukwidziridzwa kwakazara uye kushandiswa mune imwe pfungwa huru, iyo inoda kushanda pamwe kweiyo indasitiri yese. Semaitiro ekusimudzira-kuchengetedza simba, iyo yakajairwa cathode LED kuratidza skrini inosanganisira kushandiswa uye kushanda mari yemagetsi. Naizvozvo, kuchengetedza kwesimba kune hukama nezvido zve LED kuratidza skrini vanoshanda uye kushandiswa kwesimba renyika.
Kubva pane zvazvino mamiriro, iyo yakajairwa cathode LED inochengetedza magetsi skrini haizowedzere mutengo wakawandisa kana ichienzaniswa neyakajairika skrini yekuratidzira, uye inochengetedza mari mukushandiswa kwekupedzisira, iyo inoremekedzwa zvakanyanya nemusika.
