Tignoolajiyada yaraynta iyadoo la adeegsanayo LED korantada DC
Way fududahay in la beddelo dhalaalka LED-ka iyadoo la hagaajinayo socodka hore si loo hagaajiyo iftiinka. Fikirka ugu horreeya waa inuu beddelo darawalkiisa hadda, sababtoo ah iftiinka LED-ku wuxuu si toos ah u siman yahay hadda.
1.1 Habka loo hagaajiyo hadda
Habka ugu fudud ee lagu hagaajin karo hadda ee LED waa in la beddelo caabiyaha ogaanshaha hadda ee ku xiran si taxane ah oo leh culeyska LED. Ku dhawaad dhammaan chips-yada joogtada ah ee DC-DC waxay leeyihiin interface si loo ogaado hadda. Joogtada joogtada ah. Si kastaba ha ahaatee, qiimaha resistor ogaanshaha this sida caadiga ah waa mid aad u yar, oo kaliya dhowr ohms, haddii aad rabto in aad ku rakibi potentiometer ah derbiga si ay u hagaajiyaan hadda waa lagama yaabo, sababtoo ah caabbinta hogaanka ayaa sidoo kale yeelan doona ohms yar. Sidaa darteed, chips qaar ka mid ah ayaa bixiya interface danab kontoroolka ah. Beddelidda korantada kontoroolka wax gelinta ayaa bedeli karta soosaarka qiimaha joogtada ah.
1.2 Hagaajinta hadda socota waxay beddeli doontaa chromatogramka
Si kastaba ha ahaatee, isticmaalka habka hore ee hadda si loo hagaajiyo iftiinka waxay keeni doontaa dhibaato, taas oo ah, waxay bedeli doontaa heerkulkeeda iyo heerkulka midabka iyada oo la hagaajinayo dhalaalka. Waqtigan xaadirka ah, LED-yada cad waxaa soo saaray fosfoorno buluug ah oo xiiso leh oo leh nalal buluug ah. Marka hore ee hadda hoos u dhaco, iftiinka LED-yada buluuga ah ayaa kordha oo dhumucda fosfooraska jaalaha ah ma hoos u dhacayaan si saami ahaan ah, taas oo kordhinaysa hirarka ugu sarreeya ee spectrum. Tusaale ahaan, marka hore ee hadda jira uu yahay 350mA, heerkulka midabku waa 5734K, iyo marka hore u kordho 350mA, heerkulka midabku wuxuu u wareegayaa 5636K. Marka hadda la sii yareeyo, heerkulka midabku wuxuu isu beddeli doonaa midabyo diiran.
Dabcan, dhibaatooyinkani ma noqon karaan dhibaato weyn guud ahaan iftiinka dhabta ah. Si kastaba ha noqotee, nidaamka RGB LED, waxay keeni doontaa isbeddel midab leh, iyo isha bini'aadamka ayaa aad u nugul isbedelka midabka, sidaas darteed sidoo kale lama ogola.
