一, Waa maxay sababta ugu weyn ee dhibaatada soo bandhigay LED kaliya muujinaya kala bar shaashadda?
Sideen u hagaajin karnaa?
1. Meesha bandhigtu waa khalad: Tan waxaa lagu hagaajin karaa iyadoo dib loo dajinayo cabbirka cabbirka aagga bandhigga software-ka dib-u-ciyaarista shaashadda.
2. Dejinta cabbirka farta oo aad u weyn: weli hagaajinta cabbirka farta marka la ciyaarayo software
3. Arrinka guddiga cutubka: Dabcan, looxa waa jabay lamana soo bandhigi karo.Maaha wax caadi ah in la beddelo guddiga
Dhibaatada sidaan oo kale ah badiyaa waa mushkilad dejinta.Waxa kale oo suurtogal ah in unugga uu ciladoobay.Laakin itimaalka waa mid yar.Aynu eegno dhibaato la mid ah sida sawirka ka muuqata:
Dhibaatadan waxaa inta badan keena arrimaha qalabka, badanaa waxaa keena arrimaha soo socda.
1. Arrinta xadhigga korontada: Sida shayga ugu horreeya ee laga saaray.Waxay u badan tahay in xadhkaha korantada ee sabuuradda cutubku ay dabacsan tahay, taasoo keentay soo bandhigid aan dhamaystirnayn.
2. Arrinka Korontada: Inta badan tan waxaa keena cilladda moduleka korontada, waxaana loo baahan yahay in korontada la beddelo, laakiin xaaladdani maaha mid caadi ah.Sida bartilmaameedka labaad ee baaritaanka.
3. Xakamaynta waxyeelada kaadhka: Khasaaraha kaarka xakamaynta wuxuu keenaa khaladaadka gudbinta xogta ama gudbinta aan dhamaystirnayn.
4. Arrinta guddiga cutubka: Dabcan, looxa waa jabay lamana soo bandhigi karo.Maaha wax caadi ah in la beddelo guddiga.
二, Sida loo maareeyo leexashada midabka ee shaashadaha bandhiga LED?
Marka la eego dhinaca moduleka soo bandhigay LED, leexashada midabka iyo qurxinta u dhexeeya modules waa iswaafaqayn.waa maxay dhibku?
Marka hore, faham sababaha ugu waaweyn ee leexashada midabka ee modules-yada LED:
1. Dhibaatooyinka nalalka LED: (oo ay ku jiraan jaangooyooyin jajab ah oo aan iswaafajin, cilladaha baakadaha alaabta koollada, khaladaadka meelaynta inta lagu jiro hagaajinta crystal, iyo khaladaadka inta lagu jiro kala-soocidda midabka), taas oo saameyn karta hirarka dhererka, dhalaalka, iyo xagasha nalalka LED ee isla dufcaddii la mid ah. .Sidaa darteed, waxaa jira nidaam aad muhiim u ah soo saarista bandhigyada elektiroonigga ah ee LED: isku dhafka nalalka.Isku qas dhammaan nalalka LED ee isku midabka ah si siman ka hor inta aanad gelin PCB-ga.Faa'iidada in sidaas la sameeyo waa in ay ka fogaato ka leexashada midabka degaanka ee module LED ah.
2. Habka wax-soo-saarka: Ka dib marka moduleka LED-ku uu maro alxanka hirarka iyo booska LED-ka, waa inaan mar kale la dhaqaajin.Laakiin shirkado badan ayaa inta badan isku dhaca oo leexiya nalalka LED inta lagu jiro tijaabada, hagaajinta, alxanka, gabowga, iyo hababka wareejinta sababtoo ah la'aanta xaaladaha ilaalinta.Ka dib, ka hor inta aan la isticmaalin xabagta, waxa loo yaqaan 'line line' ayaa la sameeyaa, kaas oo si fudud u keeni kara nalalka shaashadda LED-ka inay si aan caadi ahayn u leexdaan, taas oo horseedaysa midabaynta moduleka.
3. Arrinka korontadu: Marka la naqshadeynayo shaashadaha LED-yada, way adagtahay in si cad loo fahmo agabka loo isticmaalo (oo ay ku jiraan xulashada iyo qadarka korontada), taasoo keentay dhibaatooyinka nidaamka korontada iyo koronto aan sinnayn modules LED.
4. Nidaamka xakamaynta iyo xakamaynta IC: Sababtoo ah xaqiiqda ah in soo-saarayaasha shaashadda LED-yada aysan haysan naqshadeynta, horumarinta, tijaabinta, iyo awoodaha wax-soo-saarka ee nidaamyada xakamaynta shaashadda LED-ka iyo xakamaynta ICs.Shaashadda soo-bandhigidda lama dammaanad qaadi karo, waxa keliya ee la samayn karaa waa in la hagaajiyo cabbirro kala duwan.
Sidaa darteed, marka dhibaatada midabka midabka ee moduleka bandhigga LED ay sababto nalalka LED-ka iyo habka wax soo saarka, moduleka ayaa kaliya la hagaajin karaa ama la bedeli karaa.Marka ay tahay arrin koronto, waxaa lagama maarmaan ah in la beddelo iftiinka korontada, iwm. Haddii ay dhibaato ku tahay nidaamka xakamaynta iyo IC, waxaan kaliya ka codsan karnaa soo-saaraha inuu hagaajiyo ama xalliyo.
Kuwa kore waa sababaha caadiga ah iyo xalalka cilladaha shaashadda LED-ka, laga bilaabo fudud ilaa kuwa adag, iyo cilad-saarka dhibaatooyinka ugu caansan mid mid.
