Uyini umehluko phakathi kwe-RGB LED ne-LED evamile?

Umehluko omkhulu phakathiI-RGBAma-LED kanyeama-LED avamilekulele ezimisweni zabo zokukhipha ukukhanya kanye namakhono okuveza umbala.

Isimiso esikhanyayo:

I-LED evamile: Ama-LED ajwayelekile ngokuvamile angama-diode akhipha ukukhanya anombala owodwa, njengobomvu, oluhlaza okotshani noma oluhlaza okwesibhakabhaka. Akhipha ukukhanya ngokugeleza kwamandla kagesi ezintweni ze-semiconductor, kanti ukukhanya okukhishwayo kuwumbala owodwa oqinile.

I-RGB LED: I-RGB LEDuhlobo lwe-LED olungakhipha imibala emithathu eyisisekelo: obomvu, oluhlaza okotshani, noluhlaza okwesibhakabhaka. Ngokuvamile zakhiwa ama-chip amathathu e-LED ahlukene (obomvu, oluhlaza okotshani, noluhlaza okwesibhakabhaka) ahlanganiswe ndawonye, futhi ngokulungisa ukukhanya kombala ngamunye, imibala ehlukahlukene ingaxutshwa.

Ukusebenza kombala:

I-LED evamile: ingakhipha umbala owodwa kuphela futhi ayikwazi ukushintshwa.

I-RGB LED: Kungakhiqiza ukuhlukahluka kombala okungenamkhawulo ngokulungisa inhlanganisela yokukhanya okubomvu, okuluhlaza okotshani nokuluhlaza okwesibhakabhaka. Lokhu kwenzaI-RGB LEDithandwa kakhulu ezinhlelweni zokusebenza ezidinga imibala eminingi, njengokukhanya kwemibala, izikrini zokubonisa kanye nezibani zokuhlobisa.

Indlela yokulawula:

I-LED evamile: Ngokuvamile kudinga kuphela ukulawula amandla okulula.

I-RGB LED: Kudinga izifunda zokulawula eziyinkimbinkimbi kakhulu, ngokuvamile kusetshenziswa ubuchwepheshe be-PWM (Pulse Width Modulation) ukulungisa ukukhanya kombala ngamunye ukuze kufezwe ukuxubana nokushintsha kombala.

Sekukonke, ukuguquguquka kanye nokuguquguquka kwama-LED e-RGB kuholele ekusetshenzisweni kwawo kabanzi ekukhanyeni nasekuboniseni ubuchwepheshe besimanje, kuyilapho ama-LED avamile efanelekile ezinhlelweni ezilula ezidinga umbala owodwa.
