Kudzikisa chiedza kwemupendero wepamusoro (kudzima chiedza kwemupendero wepamusoro-soro) uye kudzima chiedza kwemupendero wepamusoro-soro (kudzikisa chiedza kwemupendero wepamusoro-soro) matekinoroji maviri ekudzikisa chiedza akavakirwa pamatanho ekutonga, anonyanya kushandiswa mumwenje ye LED uye masisitimu emwenje echinyakare. Pasi apa pane ongororo yekuenzanisa yeaya maviri.dzimamatekinoroji:
1. Nheyo yekushanda
Kudzikira kwemusoro:
Kucheka kwevoltage kunoitika pakutanga kwehafu yega yega yeAC cycle (phase 0°). Nekunonotsa kutangiswa kwenguva yekufambisa yethyristors (kureva, kugadzirisa angle yekufambisa), voltage inoshanda pamutoro inodzorwa, nokudaro ichigadzirisa kupenya. Semuenzaniso, kana kunonoka kweangle yekufambisa kwakakura, nguva yekufambisa ipfupi, uye kupenya kwakaderera.
Kudzikira kwemucheto wekutevera:
Kucheka kwevoltage kunoitika pedyo nekuguma kwehafu yega yega yeAC cycle (phase 180°). Nekudzima nguva yekufambisa maMOSFET kana maIGBTs isati yasvika, kudzima kunowanikwa. Semuenzaniso, kana nguva yekudzima magetsi ikanonoka, voltage inoshanda inodzikira, uyederedza chiedza.
2. Zvikamu zveCore
Kudzikira kwemusoro:
Inoshandisa thyristors (SCR/Triac) semidziyo yekuchinja, iyo iri midziyo inodzorwa zvishoma (inogona chete kudzora conduction, kwete kudzima).
Kudzikira kwemucheto wekutevera:
Inoshandisa maMOSFET kana maIGBT semidziyo yekuchinja, inova midziyo inodzorwa zvizere (inogona kudzora zvese conduction ne turn-off).
3. Kuenzanisa Kwekushanda
| Chinhu | Kudzikira kwemusoro-soro | Kudzikira kwemucheto wekutevera |
| Rudzi rweDimming | Yakafara (asi inogona kusadzima zvizere kana chiedza chakaderera) | Yakamanikana zvishoma, asi yakagadzikana zvakanyanya |
| Kuenderana | Inoda kuenderana ne thyristor dimming systems uye ine mutoro mudiki unodiwa | Hapana mutoro unodiwa zvishoma, wakakodzera midziyo ine simba shoma |
| Kupenya & Ruzha | Inowanzo kanganiswa nemagetsi uye inodzima-frequency flue | Ruzha rwakaderera, kudzima kwakadzikama |
| Kugona Kudzima | Inogona kusiya simba remagetsi risina kusimba (dambudziko rekupenya kwe LED) | Inogona kudzima zvizere, hapana zvasara zvemazuva ano |
| Mutengo & Kuoma Kwazvo | Mutengo wakaderera, dunhu riri nyore, rinoenderana netambo dzechinyakare | Dunhu rakakosha uye rakaoma kunzwisisa |
4. Pfupiso yeZvakanakira neZvakaipa
Zvakanakira zveDimming:
Tekinoroji yakachipa, yemazuva ano, inoenderana nehurongwa hwekudzima thyristor huripo (semuenzaniso, incandescent yechinyakare)zvidimbu zvechiedza).
Kudzikira kweDimming Kunotungamira Zvakaipa:
Zvinogona kukonzera kupenya kwe LED, kukanganiswa kwemagetsi, uye zvinogona kusadzima zvizere kana zvinhu zvidiki.
Zvakanakira zveDimming Trailing-edge:
Kudzima kwakadzikama, hakuna kupenya, kunotsigira zvinhu zvinokwanisa kufambiswa (semuenzaniso, madhiraivha e LED), uye kunogona kudzima zvachose.
Kudzikira kwemucheto wekutevera Zvakaipa:
Mutengo wakakwira, kuderera kwemusika, zvinonyanya kushandiswa pakudzima rambi rimwe chete rine simba shoma.
5. Maitiro Ekushandisa
Kudzikira kwemusoro:
Yakakodzera mapurojekiti ekugadzirisa magetsi echinyakare (semuenzaniso, kutsiva mababu eincandescent) uye masisitimu emagetsi ekutengeserana ane simba guru (anofanira kusangana nezvinodiwa zvishoma zvekutakura).
Kudzikira kwemucheto wekutevera:
Yakakodzera marambi e LED ane simba shoma (semuenzaniso, marambi edhesiki, marambi emumba) uye mamiriro ezvinhu anoda kudzima kwemhando yepamusoro (semuenzaniso, mamiziyamu, mahotera).
6. Maitiro Ekuvandudza Tekinoroji
Kudzikira kwemagetsi kuchiri kuenderera mberi mumusika nekuda kwezvakanaka zvakwo pamutengo, asi kudzikira kwemagetsi kuri kuwedzera zvishoma nezvishoma mukushandiswa kwekudzikisa magetsi nemazvo. Asi ese ari maviri anofanira kutarisisa kuti madhiraivha anoenderana sei, sezvo kusanganisa kwawo kunogona kukonzera kutadza kudzikisa magetsi kana kukuvara kwemudziyo.
7. Mhedziso
Kudzima kwechiedza cheLeading-edge uye kudzima kwechiedza chetrailing-edge chimwe nechimwe chine zvachakanakira nezvachinokanganisa uye chakakodzera mamiriro akasiyana ekushandiswa. Kudzima kwechiedza cheLeading-edge kunodhura zvishoma uye kunoenderana, zvichiita kuti ive yakakodzera kune mwenje yechinyakare uye masisitimu ane simba guru. Kudzima kwechiedza chetrailing-edge kunopa kudzima kwechiedza kwakapfava, kusina kudzima uye kwakakodzera kune zvinodiwa zvekudzimisa kwechiedza zvine simba shoma uye zvine kunyatsojeka. Sezvo tekinoroji ichifambira mberi, kushandiswa kwekudzimisa kwechiedza chetrailing-edge munzvimbo dzekudzimisa kwechiedza zvine kunyatsojeka kuchawedzera zvishoma nezvishoma.
