Indlela yokwandisa ngokufanelekileyo ukukhanya kwezibane ze-LED?

I-LED (i-Light Emitting Diode) ngumthombo wokukhanya oqhelekileyo kunye neenzuzo zokusebenza okuphezulu, ukuthembeka kunye nobomi obude. Kwizicelo ezininzi, sihlala sidinga ukulawula ukuqaqamba kwee-LEDs ngokweemfuno. Eli nqaku liza kwazisa iindlela eziqhelekileyo zokulawula ukukhanya kwe-LED kunye nemigaqo yazo.

1. Lungisa umsinga

Ukulungiswa kwangoku yenye yeendlela ezilula zokutshintsha ukuqaqamba kwe-LED ngokutshintsha okwangoku ngayo. Umsinga omkhulu uya kwenza i-LED ikhanye, ngelixa i-current encinci iya kuyenza i-dimmer. Le ndlela isebenza kwiisekethe ezilula ze-LED kwaye inokuphunyezwa ngokulungelelanisa umthombo wangoku, i-resistor, okanye umqhubi wangoku.

2. Ukumodareyitha kobubanzi bePulse (PWM)

Ukumodareyitha kobubanzi be-Pulse (PWM) bubuchwephesha obusetyenziswa ngokubanzi kulawulo lokukhanya kwe-LED. I-PWM ilawula ukukhanya ngokulungelelanisa ububanzi be-pulse kunye nokuphindaphinda kwee-LEDs. Umgaqo wayo kukutshintsha umlinganiselo wexesha lomgangatho ophezulu kunye nenqanaba eliphantsi le-pulse kumjikelezo ngamnye, ngaloo ndlela ulinganisa umphumo wokukhanya okuhlukeneyo. Xa kuthelekiswa nohlengahlengiso lwangoku, i-PWM inokufezekisa ukuchaneka kokukhanya okuphezulu kunye nokusetyenziswa kwamandla aphantsi.

3. Sebenzisa i-resistor variable

I-resistor variable (efana ne-potentiometer) yinto eqhelekileyo esetyenziselwa ukulawula ukukhanya kwe-LED. Ngokudibanisa i-resistor eguquguqukayo kwisiphaluka se-LED, ukukhanya kunokulawulwa ngokuguqula ukuhamba kwangoku ngokulungelelanisa ukuchasana kwe-resistor. Ukulungelelanisa ukuchasana kwe-resistor kunokulungelelanisa ukukhanya kwe-LED ngokubonakalayo, kodwa uluhlu lwayo lohlengahlengiso lunokulinganiselwa.

4. Sebenzisa umthombo wangoku ongaguqukiyo

Isekethe yomthombo wangoku rhoqo yindlela eqhelekileyo yokuqhuba i-LED, etshintsha ukukhanya ngokulungelelanisa umbane womthombo okhoyo. Umthombo wangoku oqhubekayo unokubonelela ngokuzinzile ngokugcina ukukhanya okuhambelanayo kwe-LED. Le ndlela ifanelekile kwizicelo ezifuna ulawulo oluchanekileyo lokukhanya kwe-LED kwaye zifuna uzinzo.

5. Sebenzisa itshiphu yokulawula ukuqaqamba

Ezinye iitshiphusi ezithile zomqhubi we-LED zinomsebenzi wokulawula ukuqaqamba onokuhlengahlengisa ukuqaqamba ngemiqondiso yolawulo lwangaphandle (njengegalelo lePWM). Ezi chips zidibanisa ukuqaqamba kohlengahlengiso lweesekethe ukufezekisa ulawulo oluchanekileyo lokuqaqamba. Ukusebenzisa le chip ilula uyilo lwesekethe kwaye ibonelela ngeendlela zokulawula ezibhetyebhetye.

Ukushwankathela, kukho iindlela ezininzi zokulawula ukukhanya kwe-LED, kubandakanywa ukulungiswa kwangoku, ukumodareyitha kobubanzi be-pulse, usebenzisa i-resistors variable, imithombo yangoku kunye neechips zokulawula ukukhanya. Indlela nganye ineemeko ezisebenzayo kunye nemigaqo. Ukukhetha indlela efanelekileyo ngokweemfuno ezithile kunokufezekisa ulawulo lwe-LED oluhlangabezana neemfuno zokukhanya.
