Sidee qofka caadiga ah u kala saari karaa tayada bandhiga LED? Guud ahaan, way adagtahay in lagu qanciyo isticmaalaha iyadoo lagu salaynayo is-qiimaynta iibiyuhu. Waxaa jira dhowr siyaabood oo fudud oo lagu garto tayada shaashadda LED-ka ee midabka buuxa.
1. Caafimad
Fiirinta dusha sare ee shaashadda bandhigga LED waa inay ahaataa ± 0.1mm gudahood si loo hubiyo in sawirka la soo bandhigay uusan dhalanrogmin. Soo bixitaan qayb ah ama dib u dhac ayaa u horseedi doona xagal dhintay xagal daawashada shaashadda LED-ka. Inta u dhaxaysa golaha LED-ka iyo golaha LED-ka, farqiga u dhexeeya moduleka iyo moduleka waa inuu ahaadaa gudaha 0.1mm. Haddii farqigu aad u weyn yahay, xadka shaashadda soo-bandhigidda LED-ka ayaa noqon doonta mid cad oo aragtida lama isku dubaridi doono. Tayada flatness inta badan waxaa lagu go'aamiyaa habka wax soo saarka.
2. Iftiin
Iftiinka eeshaashadda LED gudahawaa in uu ka sarreeyaa 800cd/m2, iyo dhalaalkabandhig LEDwaa in uu ka sarreeyaa 5000cd/m2 si loo hubiyo saamaynta muuqaalka ee shaashadda LED-ka, haddii kale sawirka la soo bandhigay ma cadda sababtoo ah dhalaalku aad ayuu u hooseeyaa. Iftiiminta shaashadda LED-ka ma aha mid iftiimaya sida ugu macquulsan, waa inay ku habboonaato iftiinka xirmada LED-ka. Si indho la'aan ah u korodhka hadda si loo kordhiyo dhalaalka waxay keenaysaa in LED-ku si degdeg ah u yaraado, iyo nolosha bandhigga LED si degdeg ah ayay u yaraan doontaa. Iftiinka bandhigga LED waxaa inta badan lagu go'aamiyaa tayada nalka LED.
3. xagasha daawashada
Xagasha daawashada waxa ay tilmaamaysaa xagasha ugu badan ee aad ka arki karto dhamaan shaadhka LED-ka ee shaashadda fiidyaha LED-ka. Baaxadda xagasha daawashada ayaa si toos ah u go'aamisa dhagaystayaasha muraayadda LED-ka, markaa way ka weyn tahay, xagasha daawashada waa in ka badan 150 darajo. Baaxadda xagasha daawashada waxaa inta badan lagu go'aamiyaa habka baakadaha ee nalalka LED-ka.
4. dheelitirka cad
Saamaynta dheelitirka cad ayaa ah mid ka mid ah tilmaamayaasha ugu muhiimsan ee muujinta LED. Dhanka midabka, caddaan saafi ah ayaa la soo bandhigi doonaa marka saamiga saddexda midab ee casaanka, cagaarka iyo buluugga ah uu yahay 1: 4.6: 0.16. Haddii uu jiro wax yar oo leexsan saamiga dhabta ah, waxaa jiri doona leexasho dheelitirka cad. Guud ahaan, waa lagama maarmaan in fiiro gaar ah loo yeesho in caddaanku yahay buluug ama huruud. ifafaale cagaaran. In monochrome, farqiga yar ee dhalaalka iyo hirarka u dhexeeya LEDs, ka wanaagsan. Ma jiro kala duwanaansho midab ama midab leh marka la taagan yahay dhinaca shaashadda, iyo joogteynta ayaa ka fiican. Tayada dheelitirka cad waxaa inta badan lagu go'aamiyaa saamiga dhalaalka iyo dhererka nalka LED-ka iyo nidaamka xakamaynta shaashadda LED-ka.
5. Midab dhimis
Dib-u-dhisidda midabka waxaa loola jeedaa midabka lagu soo bandhigay muraayadda LED-ka waa inuu ahaadaa mid aad u waafaqsan midabka isha dib-u-ciyaarista, si loo hubiyo xaqiiqada sawirka.
6. Haddi ay jirto mosaic iyo ifafaale bar dhintay
Mosaic waxaa loola jeedaa labajibbaaran yaryar oo had iyo jeer dhalaalaya ama had iyo jeer madow ku yaal shaashadda LED, taas oo ah ifafaale necrosis module. Sababta ugu weyn ayaa ah tayada IC ama laambada loo isticmaalo bandhigga LED ma fiicna. Dhibicda dhintay waxaa loola jeedaa hal dhibic oo had iyo jeer dhalaalaya ama had iyo jeer madow ku yaal shaashadda LED-ka. Tirada dhibcooyinka dhintay inta badan waxaa lagu go'aamiyaa tayada dhinta iyo haddii tillaabooyinka lidka ku ah soo-saaruhu ay qumman yihiin.
7. leh ama aan lahayn blocks midabka
Xirmooyinka midabka waxa loola jeedaa farqiga midabka cad ee u dhexeeya qaybaha ku xiga. Kala-guurka midabku wuxuu ku salaysan yahay moduleka. Ifafaalaha xannibaadda midabka waxaa inta badan sababa nidaamka xakamaynta liidata, heerka cawl hooseeya iyo inta jeer ee iskaanka oo hooseeya.
8. Muujinta xasilloonida
Xasilooni waxa loola jeedaa tayada lagu kalsoonaan karo ee muujinta LED-ka ee tallaabada gabowga ka dib marka la dhammeeyo.
9. Amniga
Muujinta LED-ku waxay ka kooban tahay armaajooyin badan oo LED ah, armaajo kasta oo LED ah waa in la dejiyaa, caabbinta dhulkana waa in ay ka yar tahay 0.1 ohms. Oo u adkeysan kara danab sare, 1500V 1min burbur la'aan. Calaamadaha digniinta iyo hal-ku-dhegyada ayaa looga baahan yahay terminalka wax-soo-gelinta korantada-sare iyo fiilooyinka korantada-sare ee sahayda korontada.
10. Baakaynta iyo rarida
Shaashadda LED-ku waa badeecad qiimo leh oo miisaankeedu aad u weyn yahay, habka baakadaha ee ay adeegsato soo-saareyaashu waa mid aad muhiim u ah. Guud ahaan, waxaa lagu baakadeeyay hal armaajo LED ah, iyo dusha kasta oo ka mid ah golaha LED-ka waa inuu lahaadaa walxo ilaalin ah si loo daboolo, si LED-ku u yeesho meel yar oo loogu talagalay hawlaha gudaha inta lagu jiro gaadiidka.
