Nzira shanu dzeDimming dzeMagetsi e LED

Kune mwenje, dimming yakakosha.Dimming haingogadziri mhepo yakagadzikana, asiwo inowedzera kushandiswa kwemwenje. Uyezve, kune magetsi e LED, kudzima kuri nyore kuona kupfuura mamwe marambi efluorescent, mwenje inoponesa simba, high-pressure sodium mwenje, nezvimwewo, saka inonyanya kukodzera kuwedzera dimming mabasa kune akasiyana marudzi emarambi e LED.Ndedzipi nzira dzekudzima mwenje dzine?

1.Leading edge phase cut control dimming (FPC), inozivikanwawo se SCR dimming

FCP ndeye kushandisa waya dzinodzoreka, kutanga kubva pa AC hama chinzvimbo 0, yekupinda voltage chopping, kusvika waya dzinodzoreka dzabatana, hapana magetsi ekuisa.

Nheyo yacho ndeyekugadzirisa maitiro ekuitisa kwehafu-wave yealternating ikozvino kushandura sinusoidal waveform, nekudaro ichishandura kukosha kunoshanda kweiyo alternating ikozvino, kuitira kuti uwane chinangwa chekudzima.

Zvakanakira:

wiring yakanakira, mutengo wakaderera, kurongeka kwepamusoro, kunyatsoita zvakanaka, hukuru hudiki, huremu huremu, uye nyore kudzora kure.Inotonga pamusika, uye zvigadzirwa zvevagadziri vazhinji imhando iyi ye dimmer.

Zvakaipa:

kuderera kwekuita zvishoma, kazhinji kunoguma nekuderedza dimming range, uye kuchaita kuti hushoma hunodiwa mutoro upfuure simba rakarongwa reimwe chete kana nhamba shoma yemwenje ye LED, kuderera kwekugadzirisa uye kuderera kunoenderana.

2.trailing edge cut (RPC) MOS tube dimming

Trailing-edge phase-cut control dimmers dzakagadzirwa nefield-effect transistor (FET) kana insulated-gedhi bipolar transistor (IGBT) zvishandiso.Trailing edge phase-cut dimmers anowanzo shandisa MOSFETs semadhizha ekuchinja, saka anonziwo MOSFET dimmers, anowanzozivikanwa se "MOS machubhu".MOSFET ishanduko inodzorwa zvizere, inogona kudzorwa kuve yakabatidzwa kana kudzima, saka hapana chiitiko chekuti thyristor dimmer haigone kudzimwa zvachose.

Pamusoro pezvo, iyo MOSFET dimming circuit inonyanya kukodzera capacitive load dimming kupfuura thyristor, asi nekuda kwemutengo wakakwira uye nedunhu rakaomarara, hazvisi nyore kugadzikana, zvekuti nzira yeMOS tube dimming haisati yagadzirwa. , uye iyo SCR Dimmers ichiri kuverengera huwandu hukuru hweiyo dimming system musika.

3.0-10V DC

0-10V dimming inonziwo 0-10V chiratidzo dimming, inova nzira yeanalog dimming.Musiyano waro kubva kuFPC ndewekuti kune mamwe maviri 0-10V interfaces (+10V uye -10V) pane 0-10V magetsi.Iyo inodzora kubuda kwemagetsi emagetsi nekushandura 0-10V voltage.Dimming inowanikwa.Inopenya zvakanyanya kana iri 10V, uye inodzima kana iri 0V.Uye 1-10V ndiyo chete dimmer iri 1-10V, kana dimmer yekudzivirira ichigadziriswa kusvika kudiki 1V, kubuda ikozvino 10%, kana kubuda ikozvino 100% pa10V, kupenya kuchavawo 100%.Zvakakosha kucherechedza uye chinhu chakanakisisa chekusiyanisa ndechokuti 1-10V haina basa rekushandura, uye mwenje haugoni kugadziriswa kusvika kune yakaderera, nepo 0-10V ine basa rekushandura.

Zvakanakira:

yakanaka dimming mhedzisiro, kuenderana kwakanyanya, kurongeka kwakanyanya, kuita kwemutengo wakakwira

Zvakaipa:

yakaoma wiring (wiring inoda kuwedzera mitsetse yechiratidzo)

4. DALI (Digital Addressable Lighting Interface)

Iyo DALI chiyero yakatsanangura network yeDALI, kusanganisira inokwana makumi matanhatu nemana mayunitsi (ane kero dzakazvimirira), mapoka gumi nematanhatu uye gumi nematanhatu.Akasiyana mayuniti ekuvhenekesa pabhazi reDALI anogona kuiswa mumapoka kuti aone kutonga uye kutonga kwezviitiko zvakasiyana.Mukuita, yakajairwa yeDALI system application inogona kudzora 40-50 mwenje, iyo inogona kukamurwa kuita 16 mapoka, uku uchikwanisa kugadzirisa zvimwe zvinodzora / zviratidziro zvakafanana.

Zvakanakira:

Yakarurama dimming, mwenje mumwe uye imwechete kutonga, maviri-nzira kutaurirana, yakanakira kubvunza panguva uye kunzwisisa kwemidziyo mamiriro uye ruzivo.Yakasimba kurwisa-kupindira kugona Kune akakosha maprotocol uye mirau, iyo inosimudzira kudyidzana kwezvigadzirwa pakati pemhando dzakasiyana, uye imwe neimwe yeDALI mudziyo ine yakaparadzana kero kodhi, iyo inokwanisa zvechokwadi kuwana imwechete-mwenje kutonga.

Zvakaipa:

mutengo wakakwira uye yakaoma debugging

5. DMX512 (kana DMX)

DMX modulator ndiyo chidimbu cheDigital Multiple X, zvinoreva kuti akawanda dhijitari kutapurirana.Zita rayo repamutemo ndiDMX512-A, uye imwe interface inogona kubatanidza kusvika 512 chiteshi, saka chaizvo tinogona kuziva kuti mudziyo uyu idhijitari yekufambisa dimming mudziyo ine 512 dimming chiteshi.Iyo yakabatanidzwa yedunhu chip inopatsanura masaini ekudzora akadai sekupenya, musiyano, uye chromaticity, uye anoagadzirisa zvakasiyana.Nekugadzirisa iyo potentiometer yedhijitari, iyo analog yekubuda level kukosha inoshandurwa kudzora kupenya uye hue yechiratidzo chevhidhiyo.Inopatsanura chiyero chechiedza kuita 256 mazinga kubva pa0 kusvika ku100%.Iyo yekudzora sisitimu inogona kuona R, G, B, 256 marudzi egrey mazinga, uye kunyatsoona yakazara ruvara.

Kune akawanda einjiniya maapplication, zvinongodiwa chete kumisikidza diki dhizaini mubhokisi rekugovera padenga, pre-program chirongwa chekudzora mwenje, chengeta muSD kadhi, uye uiise mudiki diki rekutonga padenga. kuziva hurongwa hwemwenje.Dimming control.

Zvakanakira:

Chaiyo dimming, hupfumi hunochinja mhedzisiro

Zvakaipa:

Yakaoma wiring uye kunyora kero, yakaoma debugging

Isu tine hunyanzvi mumwenje unodzima, kana iwe uchida kuziva zvakawanda nezve mwenje uye dimmers, kana kutenga ma dimmers anoratidzwa muvhidhiyo, ndapota.taura nesu.
