Uthini umahluko phakathi kwe-RGB ye-LED kunye ne-LED eqhelekileyo?

Umahluko ophambili phakathiRGBLEDs kunyeii-LED eziqhelekileyoilele kwimithetho-siseko yazo ekhupha ukukhanya kunye nesakhono sokubonisa umbala.

Umgaqo oqaqambileyo:

I-LED eqhelekileyo: Ii-LED eziqhelekileyo zihlala zikhanyisa ii-diode zombala omnye, njengobomvu, obuluhlaza okanye obuluhlaza. Zikhupha ukukhanya ngokuhamba kombane ngoku kwimathiriyeli ye-semiconductor, kwaye ukukhanya okukhutshiweyo ngumbala omnye osisigxina.

I-RGB ye-LED: I-RGB ye-LEDluhlobo lwe-LED olunokukhupha imibala emithathu esisiseko: obomvu, oluhlaza, noluhlaza okwesibhakabhaka. Ngokuqhelekileyo ziqulunqwe ngee-chips ezintathu ze-LED ezihlukeneyo (ezibomvu, eziluhlaza, kunye ne-blue) zidityaniswe kunye, kwaye ngokulungelelanisa ukukhanya kombala ngamnye, imibala eyahlukeneyo inokuxutywa.

Ukusebenza kombala:

I-LED eqhelekileyo: inokukhupha umbala omnye kwaye ayinakuguqulwa.

I-RGB ye-LED: Inokuvelisa phantse ukwahlukana kombala okungenasiphelo ngokulungelelanisa indibaniselwano yokukhanya ebomvu, eluhlaza kunye nohlaza okwesibhakabhaka. Oku kwenzaI-RGB ye-LEDidume kakhulu kwizicelo ezifuna imibala emininzi, efana nokukhanya kombala, izikrini zokubonisa kunye nezibane zokuhombisa.

Indlela yokulawula:

I-LED eqhelekileyo: Ngokuqhelekileyo kufuna kuphela ulawulo olulula lwamandla.

I-RGB ye-LED: Ifuna i-circuit control eyinkimbinkimbi, ngokuqhelekileyo isebenzisa iteknoloji ye-PWM (Pulse Width Modulation) ukulungisa ukukhanya kombala ngamnye ukufezekisa ukuxuba kombala kunye nokutshintsha.

Ngokubanzi, ukuguquguquka kunye nokuguquguquka kwee-LED ze-RGB kuye kwakhokelela ekusebenziseni kwabo ngokubanzi ukukhanya kwanamhlanje kunye nobuchwepheshe bokubonisa, ngelixa ii-LED eziqhelekileyo zifanelekile kwizicelo ezilula ezifuna umbala omnye.
