TRIAC Dimming vs PWM Dimming
PWM inomirira "Pulse-Width Modulation". Kusiyana neanalog TRIAM dimming, PWM ine digital dimming tekinoroji. Iyi inzira inoshanda yekudzora analog maseketi anoshandisa kuburitsa kwedhijitari yemicroprocessor. Kuyera kusimba kweanalogi zviratidzo zvakare nyore ne pulse-width modulation (PWM). Iwe unogona kushandura kutenderera kwebasa resquare wave nekushandisa ma-high-resolution counters.
Iyo PWM siginecha inoramba iri yedhijitari kunyangwe iyo yakazara-chiyero DC inopihwa isiripo nguva dzose. Kana iyo mwenje yakabatana neiyo DC inopa, inobatidza. Zvekare, kana pasina DC inopa, simba rinodzima, mwenje unomira kugamuchira chiratidzo, uye unodzima.
PWM inoshandiswa mundima dzakawanda; semuenzaniso- inoshandiswa mukuyera, kutaurirana, kutonga kwesimba uye kutendeuka, uye mwenje we LED. Iri nyore kushandisa uye inoenderana nekuwanda kwemwenje. Izvi zvinodaro nekuti mazhinji emazuva ano mamicrocontrollers uye DSPs ane PWM controller akavakirwa mukati chaimo chip. Izvi zvinoita kuti kutonga kwedhijitari kuve nyore mukuzara kune TRIAC dimming, iyo isingaenderane nema LED ese. Kunze kwezvo, unogona kucheka mutengo wesimba nekuchinja analog TRIAC dimmer kuita dhijitari PWM dimmer.

Industrial Giredhi Alternatives kune TRIAC Dimmer
DMX Dimming
DMX inomirira "Digital Multiplex Signal". Iyo idhijitari protocol inodzora akawanda emwenje zvigadziriso kana chiteshi kubva panzvimbo imwechete. Kuenzaniswa neTRIAC, DMX inopa mamwe anochinjika uye akanyatso kudzora. Mumwe chete DMX controller anogona kudzora anosvika 512 chiteshi pane zvakasikwa (boka reDMX zvigadziriso). Izvi zvinokutendera kuti udzore kure simba, kupenya, uye ruvara rwema LED chaiwo. DMX inokodzera kuisirwa hombe-yakakura senge mwenje wedariro, mwenje wekuvaka, nezvimwe.
DALI Kudzora
Kune mamwe epamberi uye anochinjika kutonga kwe LEDs, DALI inzira yakanaka kune TRIAC. Inoshanda zvakanyanya neDALI mwenje, Mwenje dze LED, LED accent lights, uye LED linear systems. Kuti uite waya yeDALI dimming, unoda tambo yekudzora ine macores maviri. Mushure mekugadzwa kwekutanga kwaitwa, masisitimu ekutonga emwenje anoita kuti zvibvire kudzoreredza masekete emwenje nedhijitari.
Ivo vanopa huwandu hwakasiyana hwekugona dimming iyo isina yemazuva ano dimming tekinoroji inogona kurova. Nekuda kweizvi, unogona kushandisa yazvino vhezheni yeDALI kudzora ese RGBW uye inobatika chena mwenje. Kunze kwezvo, madimming blasters ane mazinga eDALI anogona kubata zviri nyore kunyangwe zvakanyanya kuoma-kuchinja-mavara maapplication.
