Heerka qaboojinta eeShaashadda shaashaddawaa halbeeg aad u muhiim ah. Waxaan ognahay inay jiraan dhowr nooc oo heerar dib-u-cusbooneysiin ah oo loogu talagalay shaashadaha shaashadda ee LED, sida 480hz, 960hz, 1920hz, oo ah 3840hz, oo loo yaqaan burush hooseysa iyo burush aad u sareeya ee warshadaha. Marka waa maxay xiriirka ka dhexeeya heerka qaboobaha ee shaashadda shaashadda ee hogaaminta? Maxaa go'aamiya heerka qaboojiyaha? Saameyn noocee ah ayay ku leedahay aragtidayada aragtidayada? Intaa waxaa sii dheer, waa maxay heerka ugu habboon ee qaboobaha ee loo yaqaan 'LED' ee loo qoondeeyay shaashad weyn? Kuwani waa qaar ka mid ah su'aalaha xirfadaha, isticmaaleyaasha sidoo kale waa la jahwareerin karaa markii la doortay. Maanta, waxaan ku siin doonaa jawaab faahfaahsan oo ku saabsan su'aasha ah heerka ugu hooseeya ee nasashada!
Fikradda heerka qaboojinta
Heerka qaboojinta eeShaashadda shaashaddaWaxaa loola jeedaa tirada jeer ee sawirka la soo bandhigay si isdaba joog ah loogu muujiyo shaashadda ilbiriqsi kasta, oo lagu cabiro Hz, oo sidoo kale loo yaqaan hertis. Tusaale ahaan, shaashadda shaashadda hogaamiyaha leh oo leh heerka ugu sarreeya ee 1920 waxay soo bandhigaysaa 1920 jeer daqiiqaddii. Heerka qaboobaha ayaa badanaa saameeya tilmaame weyn oo ah in shaashada shaashadda inta lagu jiro soo bandhigida, oo inta badan ay saameyso laba waji: saamaynta toogashada iyo khibradda aragtida isticmaalaha.
Waa maxay dib-u-cusboonaysiinta sare iyo kuwa hooseeya?
Guud ahaan, heerka qaboojinta ee naqshadaha keli ah iyo dulus ee soo bandhigaya ee labadaba waa 480hz, halka ay jiraan laba nooc oo heerar dib-u-cusboonaysiin ah oo loogu talagalay bandhigyada midabka leh: 960hz, 1920hz, iyo 3840hz. Guud ahaan, 960hz iyo 1920hz waxaa lagu tilmaamaa heerarka dib-u-cusbooneysiinta oo hooseeya, 3840hz waxaa lagu tilmaamaa heerarka qaboobaha sare.
Waa maxay heerka qiiqa qaboojiyaha ee shaashadda shaashadda ee la xiriira?
Heerka qaboobaha ee shaashadda shaashadda ee hogaaminta ayaa la xidhiidha chip-ka dareeraha ah. Markaad isticmaaleyso chip-ka caadiga ah, heerka qaboojiyaha ayaa gaari kara oo keliya 480hz ama 960hz. Marka shaashadda shaashadda hogaamisa ay isticmaasho laba xabbo oo ah chip-ka qufulka, heerka qaboojiyaha ayaa gaari kara 1920hz. Markaad isticmaaleyso chip-ka-qarka sare ee PWM, heerka qaboojiyaha ee shaashadda shaashadda ee LED wuxuu gaari karaa 3840hz.
Waa maxay heerka ugu habboon ee qaboobaha?
Guud ahaan, haddii ay tahay shaashad shaashad oo keliya ama laba geesood ah, heerka nafaqada leh ee 480hZ ayaa ku filan. Si kastaba ha noqotee, haddii ay tahay shaashad midab buuxa leh, waxaa ugu wanaagsan in la gaaro heerka nafaqada ee 1920hz, kaasoo hubin kara khibrad aragga caadiga ah oo ka hortaga aragga muuqaalka ah inta lagu jiro aragtida muddada-dheer. Laakiin haddii had iyo jeer loo isticmaalo toogashada iyo kor u qaadida, waxaa ugu wanaagsan in laga dhigo shaashadda shaashadda ee qarashka sare ee 3840hz, sababtoo ah wasakhda biyaha ee 3840hz ma laha saamaynta biyaha inta lagu jiro toogashada, taasoo keentay saameyn wanaagsan oo muuqata.
Saamaynta heerarka heerarka sare iyo kuwa hoose
Guud ahaan, illaa iyo inta heerka heerka dareeraha ee shaashadda shaashadda ee hogaaminta ay ka sarreyso 960hz, waxaa ku dhow in lagu muujiyo isha bini-aadamka. Gaarista 2880hz ama ka kor ayaa loo arkaa wax ku oolnimo sare. Heerka sare ee qaboobaha ayaa macnaheedu yahay in shaashadda shaashadda uu deggan yahay, dhaqdhaqaaqyadu waa kuwo jilicsan oo dabiici ah, sawirkuna wuu cad yahay. Isla mar ahaantaana, inta lagu guda jiro sawir qaadista, muuqaalka lagu soo bandhigay shaashadda shaashadda ee hogaaminta majirto biyo-qabad, oo indhaha bini-aadamka ma dareemi doono raaxo la'aan markii la daawanayo, taas oo daalan muuqaal ah.
Marka heerka qiiqa qaboojiyaha ee shaashadda nasashada ee salka ku haysa badiyaa waxay kuxirantahay ujeedadeena iyo nooca loo adeegsaday. Haddii ay tahay mid keliya oo midab ama labo ah oo keliya, looma baahna in fiiro gaar ah la siiyo heerka qaboojiyaha. Si kastaba ha noqotee, haddii ay tahay qaar ka mid ah shaashadda midab-buuxda leh oo gudaha ah gudaha, iyadoo la adeegsanayo heerka 1920hz oo ah 1920hz ayaa sidoo kale ku filan, oo hadda si ballaaran ayaa loo isticmaalaa. Laakiin haddii aad u baahan tahay inaad u isticmaasho si aad ugu isticmaasho toogashada fiidiyowga ama ujeeddooyinka xayeysiinta ah, isku day inaad isticmaasho heerka sare ee 3840hz.
