Ngaba uyazi ukuba i-dimmer ayinikezeli kuphela ulawulo olungcono kubukhulu bezibane ze-LED kodwa inokonga ukusetyenziswa kwamandla? Kodwa umbuzo apha ngowokuba zonke iintlobo ze-dimmers ziyahambelana nee-LED. Impendulo nguHAYI omkhulu.
Izibane ze-LED zisebenzisa itekhnoloji eyahluke kakhulu kuneebhalbhu zemveli ezifana ne-incandescent kunye ne-fluorescent. Ke, ilunge kakhulu i-dimmers eyenzelwe ngokukodwa ii-LEDs.
Ngaphandle kokulibazisa okungaphaya, makhe sijonge iintlobo ezahlukeneyo ze-dimmer kwaye sikhethe eyona ifanele i-LED:
Kutheni i-Dimmer ibalulekile kwii-LEDs?
Ukunciphisa ukusetyenziswa kwamandla
Xa usebenzisa isibane ngokuqaqamba ngokupheleleyo, kutshisa amandla amaninzi. Kodwa njengoko unciphisa ukukhanya, umbane omncinci uhamba kwii-LEDs. Ngaloo ndlela, ukukhanya okuncitshisiweyo kunciphisa ukusetyenziswa kwamandla. Ngenxa yoko, amandla angaphantsi asetyenziswayo, nto leyo egcina amatyala ombane.
Ibonelela nge-Ambiance Customization Facility
Ngaba udiniwe kukusebenza kwidesika yakho iiyure kwaye ufuna ukuphumla? I-dimmer apha ikuvumela ukuba wehlise ukuqaqamba kokukhanya kwaye wenze i-ambiance ekhululekileyo kwindawo yakho. Ngale ndlela, i-dimmer ikunika indawo yokulungelelanisa ukukhanya okuhambelana neemfuno zakho.
Iqinisekisa ukuKhanya okukhululekileyo
Cinga ngegumbi lakho lokulala; usoloko ufuna ukukhanya okuqaqambileyo phaya? Akunjalongo noko. Ngelixa ufunda okanye usebenza, ukukhanya okuqaqambileyo kulungile. Kodwa xa uphumle ebhedini, ngokuqinisekileyo ukhetha ukukhanya okumnyama kunye nokuthambileyo. Ukukhanya okuqaqambileyo kweli nqanaba kunokungakhululeki kakhulu. Ilitha elivela ekukhanyeni okuqaqambileyo libangela uxinezeleko lwamehlo. Iphinda ithintele ukuphumla kwakho kwaye ichaphazele umjikelo wakho wokulala. Kwimeko enjalo, i-dimmer inciphisa ngokufanelekileyo ukukhanya kwakho izibane zokulala kwaye ikubonelela ngokukhanya okutofotofo kunye nokuthomalalisayo.
Ukwandiswa kobomi be-LEDs
Ukunciphisa ukukhanya kunciphisa uxinzelelo lwe-thermal kwi iiglowubhu kokomelela ngakumbi. Xa uqhuba i-LED kwinqanaba layo lokuqaqamba ngokupheleleyo okanye ukoyisa, iba shushu kakhulu. Oku kuchaphazela ngqo ubomi bokukhanya. Ngaloo ndlela, kufuneka utshintshe ukukhanya. Ukunciphisa isibane akusitshisi kakhulu kwaye kugcina isixhobo sisebenza ixesha elide. Ngoko ke, ukusebenzisa i-dimer ingaba sisisombululo esineendleko ngexesha elide.
Zisebenza njani iiSwitshi zeDimmer?
Umsebenzi oyintloko wokutshintsha kwe-dimmer kukunciphisa ukukhanya; oko kukuthi, ukunciphisa ukuqaqamba kwesixhobo. Kule nto, i-dimmer inciphisa ukuhamba kombane ngaphakathi kwee-LED. Ngenxa yombane ophantsi, ukukhanya kokukhanya kuyancipha; ngenxa yoko, ukukhanya kuyancipha.
Nangona kunjalo, iitekhnoloji ezahlukeneyo zisetyenziswa ekutshintsheni kwe-dimmer. Ngokusekelwe kobu buchwepheshe, indlela yokusebenza ye-dimmer iyahluka. Umzekelo, ezinye iiswitshi ze-dimmer, endaweni yokunciphisa i-voltage, zitshintshe ngokukhawuleza umbane kwaye zicime, zibonelela ngenqanaba lokukhanyisa elinokwakho kubasebenzisi. Siza kufunda iinkcukacha malunga nazo zonke iintlobo ze-dimmers kwicandelo elilandelayo.
Uhlobo lweDimmer ye-LED
1. Phase Dimming
In isigaba sobumnyama, i-dimmer ilungisa i-voltage ukuze inciphise izibane. I-wiring eyongezelelweyo ayifuni ukuguqula i-AC voltage waveform. Apha, i-dimmer idityaniswe kuthotho kunye nocingo oluphambili lonikezelo lwamandla kwaye ixhasa ukufiphala ukusuka kwi-1% ukuya kwi-100% ngokuxhomekeke kumthamo ohlukeneyo.
Ngokusekwe kwi-AC voltage waveform cut, ukufiphala kwesigaba kunokuba ziintlobo ezimbini; ezi zilandelayo:
a. I-Elead Edge Dimmers
I-Lead edge dimmers inqumle isiqalo (i-lead edge) ye-AC waveform usebenzisa i I-TRIAC. Ezi dimers zidla ngokusetyenziswa ekukhanyeni kwemveli, ezifana ne-halogen kunye ne-incandescent bulbs. Nangona kunjalo, ezinye izibane ze-LED zemodeli endala kunye nabaqhubi abahambelanayo nazo zisebenzisa iidimmers ezikhokelayo.

Isikhokelo sokukhetha eyona Dimmer ilungileyo ye-LED
1. Ukuhambelana ne-LED
Ngaphambi kokukhetha i-dimmer ye-LED yakho, jonga kuhlobo lwe-dimmer. Khumbula, ii-LEDs azihambelani nazo zonke iintlobo zeedimmers. Idimer oyikhethayo kufuneka ibe yi-trailing edge dimmer, 0-10V, DALI, okanye iDMX. Ukusetyenziswa ngokubanzi, i-edge elandelwayo iyahambelana ngokubanzi. Nangona kunjalo, isibane esihambelana nomphetho wokulandela ayithethi ukuba iya kusebenza kunye ne-DMX. Ke, ngelixa uthenga ibhalbhu yesibane, jonga ukuhambelana kwayo nokuncipha kokukhanya.
2. Umthwalo womthwalo
Nangona izibane ze-LED zisebenzisa amandla amancinci kunezixhobo zendabuko, zibeka uxinzelelo olongezelelweyo kwi-dimmer. Ngesi sizathu, kufuneka uthenge ii-dimmers ezinomthamo wamatyeli ali-10 ngaphezulu komthamo opheleleyo weebhalbhu zakho zokukhanya ze-LED.
Umzekelo- uneebhalbhu ezintlanu ezilinganiswe njenge-10W, ngoko ke amandla ewonke apha ngu (10W x 5)= 50W. Ngoko, umthamo womthwalo we-dimmer kufuneka ube ngokuphindwe kashumi = (50W x 10) = 500W.
QAPHELA: Lo mgaqo we-10x usebenza kuphela ukuba usebenzisa iidimmers zemveli eziyilelwe izibane ze-incandescent kunye ne-halogen.
Ii-dimmers ezenzelwe i-LED zilinganiswe kanye njengomthamo womthwalo onokuwuphatha. Oko kukuthi, ukuba ibhalwe njenge-100W, inokuphatha ngokuthe ngqo ii-LED ze-100W.
3. Uluhlu lweDimming
Ukuba ufuna ulawulo olukhulu ekukhanyeni kokukhanya, ukuqwalasela uluhlu lwe-dimming luyimfuneko. Ibhekisela kumlinganiselo apho i-dimmer ikuvumela ukuba unciphise ukukhanya. I-dimmer ene-0% ukuya kwi-100% yoluhlu lobumnyama ikuvumela ukuba ulawule ngokupheleleyo amandla okukhanya. Unako kwakhona ukucima isibane usebenzisa le dimmer. Nangona kunjalo, i-dimer ebonelela nge-10% ukuya kwi-100% inokufiphala kuphela ukuya kwi-10% yokukhanya kwayo kukonke. Unokucima izibane usebenzisa i-dimmer; ifuna iswitshi eyahlukileyo. Apha ngezantsi, ndongeze uluhlu lokutyela kwiindidi ezahlukeneyo ze-LED dimmer:
