Sida Loo Doorto Chips-ka LED-yada Tayada Sare leh

Faafida COVID-19 waxay kordhisay xiisaha loo qabo aaladaha jeermiska-dilka ee UVC LED, riixaya UVC LED—badeecada weli ku jirta marxaladaha hore ee horumarka degdega ah—xagga hore.

Maaddaama tignoolajiyada UVC LED ay wali ku jirto dhallaankeeda, heerar qaran iyo mid warshadeed midna ma jiraan. Intaa waxaa dheer, maadaama aysan jirin halbeeg tijaabo ah oo la aqbali karo oo lagu cabbirayo qulqulka iftiinka iyo xoojinta jajabyada UVC LED, ma jiro wax qalab ah oo tijaabinaya UVC LED oo u hoggaansamaya heerka.

Waa maxay kala duwanaanshiyaha u dhexeeya chips LED (SMDs)? Noockee ayaan dooranayaa?

Waxaad ogaan doontaa in suuqa ay ka buuxaan fursado jahawareer leh oo kala duwan oo kala duwan oo qiimo leh haddii aad u raadiso nalalka LED-ka ee mashruuc degaan ama ganacsi. Waxa laga yaabaa in ay noqoto mid xiiso leh in la doorto qalabka LED-ka ee ugu jaban. Si kastaba ha noqotee, qalabka LED-ka ee jaban had iyo jeer maaha ikhtiyaarka ugu fiican sababtoo ah tayada iftiinka LED aad ayey u kala duwan tahay inta u dhaxaysa soosaarayaasha. Marka kaydka tamarta, waxqabadka, dayactirka, iyo xaaladaha qaarkood, kharashka beddelka la tixgeliyo, qalab LED ah oo jaban ayaa laga yaabaa inuu ku dhamaado kharash badan mustaqbalka fog. Si loo dammaanad qaado inaad si dhab ah u helayso qiimo wanaagsan lacagtaada iyo si aad u gaadho mashruuca nalalka LED-ka ee guuleysta, waa muhiim inaad si taxadar leh u qiimeyso oo aad is barbar dhigto sifooyinka qalabka LED-ka ee aad ka fiirsaneyso.

Noocyada chips LED ka kala duwan oo ballaaran Uv waxaa loo hooseya  waxaa loo isticmaali karaa in lagu abuuro laydhka laydhka LED.

Marka la barbardhigo labada nooc ee chip-ka ugu caansan suuqa ee cajaladda LED-ka, 3528 iyo 5050, waxaanu ku muujin doonaa farqiga u dhexeeya iyaga qaybaha soo socda.

Farqiga marka la barbar dhigo LED 3528 leh 5050

Dhowr chips oo LED ah ayaa loo isticmaali karaa in lagu sameeyo nalalka laydhka LED. Cabbirka chip-ka waxaa lagu tilmaamay tirooyinka aad aragto, sida 3528 iyo 5050. Cabbirrada aad kor ku aragtaan waa muraayadaha qaabkii hore ee jiray in muddo ah. Hadda, chips LED ee cabbirrada 2835, 3014, 5630, iyo 3020 ayaa xitaa is haysta oo waxtar leh. Mid kastaa wuxuu leeyahay faa'iidooyin marka si sax ah loo isticmaalo. Dhammaantood laguma xukumi karo "hal" chip.

Waxaa la isticmaalaa, gaar ahaan RGB nalalka beddela midabka, marka aad u baahan tahay oo kaliya in yar oo iftiin ah goobta shaqada. 5050 LED waxay si gaar ah ugu habboon tahay iftiiminta meelaha laga yaabo inay u nuglaadaan heerarka sare ee iftiinka dabiiciga ah tan iyo, aragti ahaan, marka la barbar dhigo xargaha isla qaddarka chips, SMD 5050 LEDs waxay soo saari karaan wax soo saar iftiin ah oo saddex jeer ka badan kan 3528 strips. Waxaa jira tiro go'an oo keliya oo ku habboon PCB-ga sababtoo ah cabbirkooda oo kordhay. 5050-yadii waxay leeyihiin xoogaa xaddidaad dhalaal ah marka habkan loo isticmaalo.

Inkasta oo ay dhaliyaan kulayl ka badan jajabyada yaryar, si kastaba ha ahaatee waxay ku sameeyaan si aad uga hooseeya noocyada kale ee iftiiminta. Si kulaylka looga wareejiyo jajabyada, LED-yadani waxay u baahan yihiin PCB dhumuc weyn.

Si ka duwan 3528 LEDs, 5050s ayaa laga yaabaa inay isku daraan saddexda jajab ee kala duwan ee ku jira weelka si ay u soo saaraan malaayiin midabyo isku dhafan.

3528 SMD LEDs ee cufnaanta sare waxay u fiican yihiin codsiyada midabada leh, inkastoo 5050 chip loo isticmaali karo codsiyada u baahan hal midab oo keliya.

Sidee loo tijaabiyaa UVC LED chip?

Cabbiraadda sifada chip I-V waa mid toos ah. Tijaabiyaha waxaa loo isticmaali karaa in si toos ah loo cabbiro, ama nidaam tijaabo toos ah oo ka samaysan sahay joogto ah iyo voltmeter ayaa la dhisi karaa. Soo-saareyaasha baakadaha LED-ka waxay ka faa'ideysan karaan tamarta iyo nidaamka tijaabada hadda ee Leeds sawir-qaade sifo tayo leh, isha korantada, ka dibna sawirta qalooca sifada I-V ka dib markay cabbiraan danab u dhigma iyagoo kala beddelaya hadda. Nidaamku waxa uu ka kooban yahay il koronto oo dibadda ah, diiqada iftiinka LED - tijaabiyaha cadaadiska, iyo mitirka shucaaca UV ee qoto dheer ee EVERFINE U-20.

Qalab lagu beddelo xagasha iyo fogaanta waxaa lagu daraa tijaabiyaha qaybinta xoogga iftiinka iftiinka, taasoo ka dhigaysa cabbirro fudud.

Cadaadiska iftiinka LED - tijaabiyaha cadaadisku wuxuu leeyahay xagal iyo aalad hagaajinta fogaanta, taasoo ka dhigaysa mid fudud in la cabbiro xoogga shucaaca ee xaglo iyo masaafo kala duwan. Korontada deganaanshaha DC waxay awood u siinaysaa nidaamka tijaabada. Isku hagaajinta wax soo saarka sahayda korontadu waxay u ogolaanaysaa in si fiican loo xakameeyo gelinta hadda ee LED-ka.

Chips-yada LED-ku waxay kormeeraan u beddelashada korontada iftiinka, waxayna xakameeyaan midabka iyo tayada iftiinka iftiinka LED-ka uu sii daayo. In kasta oo ay jiraan soosaarayaal badan oo chip LED adduunka oo dhan ah, waxaa jira kala duwanaansho la taaban karo xagga tayada chip LED iyo waxqabadka suuqa. Sameeyayaasha ugu sarreeya ee chips-ka LED-ka waxaa laga helaa Shiinaha iyo Kuuriyada Koonfureed, iyo sidoo kale shirkado caan ah oo ku yaal Mareykanka iyo Japan.

Maxay muhiim u tahay in la doorto qalabka LED-ka ee isticmaala chips-yada LED-ka ee qaaliga ah?  

Xataa ka mid ah chips LED ka dufcaddii isku mid ah, waxaa jira kala duwanaansho caadi ah midabka iftiinka, dhalaalaya, iyo danab inta lagu jiro habka wax soo saarka.

bins" sida ay tayadoodu tahay. "Bins"-ka ugu cidhiidhiga ah waxaa loo isticmaalaa jajabyada LED-ga ugu fiican, taas oo dammaanad qaadaysa in isbeddel kasta oo u dhexeeya chips uu yahay mid aad u yar ilaa aan la ogaan karin. Si kasta oo ay tahay baaxadda mashruuca iftiinka LED-kaaga, waxaad dammaanad qaadi kartaa waxqabadka LED-ka ee joogtada ah adiga oo dooranaya qalabka LED-ka adiga oo isticmaalaya chips LED tayo sare leh.

Halkee laga iibsan karaa chips LED tayo sare leh

Mid ka mid ah kuwa ugu sarreeya Uv waxaa loo hooseya  UV LED ee Shiinaha waa Tianhui Electronics . Waxyaalaha aan bixinay waxaa ka mid ah cilmi baarista iyo horumarinta sayniska, caawinta farsamada, iyo adeegga naqshadeynta Iibinta alaabta elektiroonigga ah 5. Codsiga nalka UV ee looxa microcircuit. Waxaan nahay mid ka mid ah Asia ee hogaanka xad-dhaaf ah Uv  siinta macaamiisha Kalsada UV LED , alaabta, iyo adeegyada.
