Sidee loo hagaajiyaa dhalaalka gudaha gudaha midabka LED-ka?

Waxaa jira laba siyaabood oo lagu xakameynayo dhalaalka gudaha gudaha midabka LED-ka:

1. Ku beddel hadda adigoo isticmaalaya muraayadda LED-ka ee midabka buuxa.Guud ahaan, tuubada LED waxay si joogto ah u shaqayn kartaa ilaa 20ma.Marka lagu daro buuxinta LED-ka cas, dhalaalka LED-ku wuxuu asal ahaan la siman yahay kan hadda jira.

2. Isticmaal la'aanta aragga bini'aadamka si aad u xaqiijiso xakamaynta cabbirka cawl ee qaabaynta ballaca garaaca garaaca wadnaha, taas oo ah, beddelka ballaca garaaca garaaca wadnaha (taas oo ah, wareegga waajibaadka).Ilaa inta inta jeer ee soo noqnoqda ay tahay mid sare oo ku filan, indhaha bini'aadamku ma dareemi doonaan ruxitaanka pixels-ka iftiiminaya.Sababtoo ah qaabaynta ballaca garaaca wadnaha ayaa aad ugu habboon xakamaynta dhijitaalka ah, kombuyuutarrada yaryar ayaa guud ahaan loo isticmaalaa si ay u bixiyaan nuxurka muujinta LED.Ku dhawaad ​​​​dhammaan bandhigyada LED-ka ee midabka buuxa waxay isticmaalaan qaabaynta ballaca garaaca wadnaha si loo xakameeyo cabbirka cawl.

Iftiiminta muraayadda LED-ka ee midabka buuxa ee gudaha waa in ay gaadho 1500cd/m2 ama ka badan si loo hubiyo dib-u-ciyaarista caadiga ah ee muuqaalka LED-ga midabka buuxa.Haddii kale, sawirka la soo bandhigay ma cadda sababtoo ah iftiinka hooseeya, laakiin qaar badan oo gudaha ah oo midab buuxa leh ayaa muujinaya LED-ka dhalaalku wuxuu ka sarreeyaa 5000cd / m2, saameynta dib-u-ciyaartuna aad ayey u fiican tahay inta lagu jiro maalinta, laakiin dhalaalka sare ee noocan oo kale ah wuxuu keeni doonaa wasakh iftiin halis ah. habeenkii.

Software-ka jira wuxuu hagaajiyaa iftiinka, guud ahaan wuxuu qaataa habka hagaajinta heerka 256.Xaqiiqdii, software-ku waa kaliya interface interface.Iyada oo loo marayo hawlgalka software, wareegga waajibaadka PWM ee darawalka bandhigga LED-ka oo buuxa ayaa la beddelay si loo xaqiijiyo isbeddelka dhalaalka.

Iftiiminta muraayadda LED-ka ee midabka buuxa ee gudaha ayaa aad faa'iido u leh muraayadaha LED.Ku hagaajinta dhalaalka iyada oo loo marayo software-ku waa hab iyo dhaqan aasaasi ah oo ku jira warshadaha, waxaana loo tixgeliyaa hab wax ku ool ah.Guud ahaan, ka dib marka la dhammeeyo mashruuca bandhiga LED-ka ee midabka buuxa ee gudaha, soo saarayaasha tababar gaar ah ayaa la siin doonaa software-ka, ujeedadu waa in lagu caawiyo macaamiisha inay bilaabaan ganacsiga sida ugu dhakhsaha badan.
