Ubumnyama yinkqubo yokutshintsha ukukhanya komthombo wokukhanya. Oku kwenziwa ukuseta i-ambience okanye ukonga amandla xa ukukhanya okugcweleyo kungafuneki ngokwenene. Uninzi lweenkqubo zokufiphaza ezisetyenziswa phambi kwee-LED okanye nanamhlanje zenzelwe izibane zokukhanya ze-incandescent. Ezi nkqubo zihlala zisebenzisa iindlela zobumnyama zesigaba sangaphambili kunye nesigaba sokubuyela umva apho i-dimmer iphazamisa okanye inqumle igalelo lomgca we-AC ukunciphisa amandla angena kumqhubi. Ngamandla amancinci angenayo, kuya kuba nemveliso encinci kumqhubi, kwaye ukukhanya kokukhanya kuyancipha.

Amagama angundoqo aqhelekileyo aviweyo ekukhanyeni kwe-LED yi-DMX, i-DALI, i-0/1-10V, i-thyristor (TRIAC), i-WIFI, i-Bluetooth, i-RF, kunye ne-Zigbee. Ezi zizibonakaliso zegalelo lonikezelo lwamandla olumnyama. Ukukhethwa kweempawu zegalelo ezahlukeneyo ikakhulu ngenxa yokuqwalaselwa kokusingqongileyo (ufakelo, iingcingo), umsebenzi, iindleko, kunye nokuguquguquka kokwandiswa kamva. Umgangatho wesiphumo sobumnyama simiselwa ikakhulu yimveliso yendlela yobumnyama yonikezelo lwamandla ombane, hayi indlela yokufaka ubumnyama.

Iindlela zokunciphisa imveliso yonikezelo lwamandla ombane eziluzizi zahlulwe zazintlobo ezimbini, ukuNcitshiswa kwangoku rhoqo (CCR) kunye nePulse Width Modulation (PWM) (ekwaziwa ngokuba yiAnalog Dimming).

Okokuqala, ingcaciso: eneneni, zonke iistrip ze-LED ziluzizi.

Xa uthengela izibane eziqhelekileyo zekhaya ze-LED njengeebhalbhu zesimbo sika-A, usenokubona AKUKHO DIMMABLE zidweliswe phantsi kwenkcazelo yemveliso. Ezinye iibhalbhu ze-LED azicimeki ngenxa yokuba ukujikeleza kombane ngaphakathi kwibhalbhu ye-LED ayenzelwanga ukutolika isignali yobumnyama yebhalbhu yodonga, leyo, yona, ibe/yenzelwe ibhalbhu yesiqhelo ekhanyisayo.

Kwelinye icala, imicu ye-LED ayenzelwanga ukuba idityaniswe ngokuthe ngqo kumbane ophezulu (umz. i-120V AC socket socket), kwaye ifuna unikezelo lwamandla ukuguqula amandla ombane aphezulu e-AC ibe yi-12V okanye i-24V DC yombane esezantsi.

Ke ngoko, ukuba umbane woludongeni ubandakanyeka, kufuneka kuqala "uthethe" kubonelelo lwamandla ngaphambi kokuba ubumnyama benzeke kumcu we-LED. Ngoko ke, umbuzo ongenakucimeka/ongacimekiyo uxhomekeke kwiyunithi yonikezelo lwamandla, kwaye ingaba iyakwazi ukutolika isignali yobumnyama eveliswe yi-wall-dimmer.

Kwelinye icala, phantse zonke iistrip ze-LED (njengakuwo, umcu ngokwawo) uyacimeka. Ukunika umqondiso ofanelekileyo wombane we-DC (ngokuqhelekileyo i-PWM), nakuphi na ukuqaqamba komcu we-LED kunokulungiswa ngokukhululekileyo.

Nceda uqaphele ukuba kukho ngokubanzi iindidi ezimbini zemigca ekhokelayo kwimarike, ngoku rhoqo kunye nombane oqhubekayo. Iimfuno zabo zonikezelo lombane oludimkileyo zahlukile. Nceda ujonge le theyibhile ingezantsi:

Yintoni elawula ukuqaqamba kwe-LED?

Isixa sangoku esihamba nge-LED simisela ukukhanya kwayo. Ukuba sijonga igrafu engentla, siya kubona ukuba ukutshintsha i-voltage kuyayitshintsha yangoku nge-LED, kusenza sicinge ngokufiphalisa i-LED ngokunyusa okanye ukunciphisa i-voltage kuyo yonke. Nangona kunjalo, sinokubona kwakhona ukuba ummandla apho sinokutshintsha i-voltage ngaphandle kokufumana ixesha elininzi langoku mncinci. Kwakhona, umsinga awuqikeleleki ngokunjalo, njengokukhanya.

Ukuba siskena ezinye iidatadata ze-LED, sinokubona ukuba ukukhanya okukhanyayo kwe-LED kuxhomekeke kumjelo ohamba phambili. Ulwalamano lwabo luphantse lube ngumgca kakhulu. Ke kwii-LED ezimnyama, sithatha amandla ombane angaphambili njengexabiso elimiselweyo kwaye silawule okwangoku endaweni yoko.

Iindlela zokufiphaza kwe-LED
