Sannado badan oo horumarineed ka dib, bandhigga caadiga ah ee anode-ka caadiga ah ee LED wuxuu sameeyay silsilad warshadeed oo deggan, taas oo keentay in ay caan ku noqoto bandhigga LED.Si kastaba ha ahaatee, waxay sidoo kale leedahay dib-u-dhacyo, heerkulka shaashadda oo xad-dhaaf ah iyo isticmaalka awoodda xad-dhaafka ah.Ka dib markii muuqaalka kore ee LED-ga caadiga ah ee tignoolajiyada awoodda bandhiga, waxay soo jiidatay dareenka weyn ee suuqa bandhiga LED.Habkan korontada ayaa gaari kara badbaadinta tamarta ugu badan ee 75%, markaa waa maxay tignoolajiyada korontada ee bandhigga cathode LED-ga caadiga ah?Waa maxay faa'iidooyinka farsamadan?
Waa maxay faa'iidooyinka tignoolajiyada sahayda korantada ee bandhigga LED-ka ee cathode caadiga ah
1. Waa maxay muuqaalka caadiga ah ee cathode LED?
"Cathode-ka caadiga ah" waxa loola jeedaa habka korontada ee cathode-ka caadiga ah.Dhab ahaantii, tani waa tignoolajiyada tamarta-badbaadinta ee bandhigyada LED.Waxa loola jeedaa isticmaalka cathode-ka caadiga ah si loo xoojiyo bandhiga LED.B (cas, cagaar, buluug) ayaa kala saara korontada, waxayna si sax ah u qaybisaa tamarta hadda iyo tamarta ee R, G, B ee nalalka, sababtoo ah R, G, B (cas, cagaar, buluug) waxay u baahan yihiin shaqada ugu fiican. danab, iyo hadda waa ka duwan yahay, Sidaa darteed, hadda ayaa marka hore dhex mari doonaa tusbaxa laambadda, ka dibna gaadho cirifka taban ee IC ah, hoos u dhac danab hore iyo yaraynaysaa caabbinta conduction gudaha.
2. Waa maxay farqiga u dhexeeya cathode-ka caadiga ah iyo bandhigyada LED-ka anode-ga caadiga ah?
①Hababka kala duwan ee korontadu:
Habka korantada ee loo yaqaan 'cathode' ee sida caadiga ah loo isticmaalo ayaa ah in kan hadda jira uu marka hore dhex maro tusaha laambada ka dibna uu gaaro cirifka taban ee wareegga isku dhafan, si hoos u dhaca korantada hore uu u yaraado oo iska caabintu u yaraato.
Anode-ka caadiga ah waa kan hadda ka soo qulqulaya guddiga PCB ee kuulka laambada, oo si siman u siiya awoodda R, G, B (cas, cagaar, buluug), si hoos u dhaca korantada ee wareegga uu noqdo mid weyn.
②Danabka sahayda korantadu way ka duwan tahay:
Kathode caadiga ah, sahayda hadda iyo danab ee R, G, B (cas, cagaar, buluug), siday u kala horreeyaan.Nalalka casaanka, cagaarka iyo buluuga ah waxay leeyihiin shuruudo koronto oo kala duwan.Qulqulka laambada gaduudan waa qiyaastii 2.8V, iyo danab ka mid ah kuwa buluugga iyo cagaarka ah ee kuulku waa 3.8V, sahayda korontadu waxay gaari kartaa koronto sax ah iyo koronto.Khasaaraha yar awgeed, kulaylka ay dhaliso bandhigga LED inta lagu jiro hawlgalka aad ayuu u hooseeyaa.
Katoodhka caadiga ah wuxuu u baahan yahay inuu siiyo R, G, B (cas, cagaar, buluug) koronto midaysan oo ka sarreysa 3.8V (sida 5V).Waqtigan xaadirka ah, danab ay heleen casaan, cagaar iyo buluug waa lebis 5V, halka casaan, cagaar, Voltaga shaqada ugu fiican ee looga baahan yahay saddexda laambad ee buluuga ah ayaa aad uga hooseeya 5V.Marka loo eego qaacidada korantada P=UI, xaaladaha joogtada ah ee hadda jira, korontadu way ka sii badan tahay, awoodda badan, taas oo ah, isticmaalka korantada ee weyn, halka bandhiga LED uu shaqeynayo kulayl badan ayaa soo baxaya habka.
3. Waa maxay sababta kulaylka caadiga ah ee LED-ka cathode uu hooseeyo?
Habka sahayda korantada ee cathode ee caadiga ah ee shaashadda qabow waxay ka dhigaysaa habka bandhiga LED inuu dhaliyo kulayl yar iyo kor u kaca heerkulka hoose.Xaaladaha caadiga ah, inta lagu jiro dheellitirka cad iyo dib-u-ciyaarista fiidiyowga, heerkulka shaashadda qabow wuxuu ka hooseeyaa 20 ° C marka loo eego bandhigga LED-ka ee caadiga ah ee isku midka ah.Marka la eego qeexitaanno isku mid ah iyo dhalaal isku mid ah, heerkulka shaashadda ee bandhigga LED-ga caadiga ah wuxuu ka badan yahay 20 digrii ka hooseeya kan alaabada bandhigga LED-ka ee anode-ga caadiga ah, iyo isticmaalka korantadu waa 50% ka hooseeya kan alaabada bandhigga anode ee caadiga ah.
Heerkulka sare ee shaashadda LED-ka iyo isticmaalka awoodda xad-dhaafka ah ayaa had iyo jeer ahaa arrimaha muhiimka ah ee saameeya nolosha adeegga shaashadda LED-ka."Bandhig LED-ga caadiga ah ee cathode" ayaa xallin kara labadan mashaakil.
4. Waa maxay faa'iidooyinka bandhigyada LED-ga ee cathode caadiga ah?
Korontadu waxay runtii badbaadisaa tamarta:
Alaabooyinka cathode-ka caadiga ah waxay qaataan tignoolajiyada kontoroolka saxda ah, marka loo eego sifooyinka kala duwan ee optoelectronic ee saddexda midab ee aasaasiga ah ee casaanka, cagaarka iyo buluuga, oo ay weheliso nidaamka xakamaynta soo bandhigida IC caqli-gal ah iyo qaab madax-bannaan oo go'an, korantada kala duwan ee LED iyo wareegga wadista waa sax loo qoondeeyay, si isticmaalka tamarta alaabadu u noqoto mid aad u sareysa.Alaabooyinka la midka ah ee suuqa yaallaa waxay badbaadiyaan ilaa 40%!
②Badbaadinta tamarta dhabta ah waxay keentaa midab dhab ah:
Habka wadista LED-ka ee sida caadiga ah loo isticmaalo ayaa si sax ah u xakameyn kara korantada, iyada oo la yareynayo isticmaalka korantada iyo kuleyliyaha, mawjadaha dhererka LED-ka ma wareegi doono inta lagu jiro hawlgalka joogtada ah, midabka dhabta ahna waxaa loo soo bandhigi karaa si adag!
③Badbaadinta tamarta dhabta ah waxay keentaa cimri dheer:
Isticmaalka tamarta ayaa la dhimay, kor u kaca heerkulka nidaamka si weyn ayaa loo dhimay, suurtogalnimada dhaawaca LED si wax ku ool ah ayaa loo dhimay, xasilloonida iyo kalsoonida nidaamka bandhigga oo dhan ayaa la wanaajiyay, iyo nolosha adeegga nidaamka ayaa si weyn loo kordhiyey.
5. Waa maxay isbeddellada tignoolajiyada xun ee caadiga ah?
Laxiriirta tignoolajiyada soo bandhiga LED-ka caadiga ah sida LED-yada, sahayda korantada, iyo darawalka ICs, uma bislaan sida silsiladda warshadaha ee Ram LED.Intaa waxaa dheer, taxanaha cathode IC ee caadiga ah hadda waa mid aan dhammaystirnayn, iyo mugga iibka guud ma aha mid weyn.Ram wali wuxuu ku jiraa 80% suuqa.
Sababta ugu weyn ee horumarka gaabis ah ee tignoolajiyada caadiga ah ee cathode hadda waa qiimaha wax soo saarka sare.Iyada oo ku saleysan wadashaqeynta silsiladda sahayda ee asalka ah, cathode-ka caadiga ah wuxuu u baahan yahay wadashaqeyn habeysan dhammaan darafyada silsiladda warshadaha sida chips, baakadaha, iyo PCB-yada, kharashkuna waa sarreeyaa.
Xilligan oo ah baahida aadka u sareysa ee badbaadinta tamarta, soo ifbaxa bandhigga LED-ka ee hufan ee caadiga ah ayaa noqday barta taageerada ee raadinta warshadahan.Si kastaba ha ahaatee, waxaa weli jira waddo dheer oo loo maro si loo gaaro dhiirrigelin iyo codsi dhammaystiran oo macno weyn leh, waxaana loo baahan yahay dadaalka wadajirka ah ee warshadaha oo dhan.Bandhigga LED-ka ee cathode caadiga ah wuxuu ku lug leeyahay isticmaalka tamarta korantada iyo kharashyada hawlgalka, taas oo ah isbeddelka horumarinta ee badbaadinta tamarta.Sidaa darteed, badbaadinta tamarta iyo dhimista isticmaalka waxay la xiriirtaa danaha hawlwadeenada bandhiga LED iyo isticmaalka tamarta qaranka.
Marka la eego xaaladda hadda jirta, muuqaalka caadiga ah ee cathode LED-ku-badbaadinta tamarta ma kordhin doonto qiimaha aad u badan marka la barbardhigo bandhigga dhaqameed, sidoo kale waxay badbaadin doontaa kharashka isticmaalka mustaqbalka, kaas oo si fiican u soo dhaweeyay suuqa.
