Uburyo butanu bwo gucana amatara ya LED

Kumucyo, gucana ni ngombwa cyane.Kugabanuka ntibishobora gusa gutuma habaho umwuka mwiza, ahubwo binongera imikoreshereze yumucyo.Ikindi kandi, kumasoko yumucyo wa LED, gucana biroroshye kubimenya kuruta andi matara ya fluorescent, amatara azigama ingufu, amatara ya sodium yumuvuduko mwinshi, nibindi, nuko rero ni byiza cyane kongeramo ibikorwa byo gucana muburyo butandukanye bwamatara ya LED.Ni ubuhe buryo bwo gucana itara rifite?

1.Gusoma icyiciro icyiciro cyo kugabanya kugenzura (FPC), bizwi kandi nka SCR dimming

FCP nugukoresha insinga zishobora kugenzurwa, guhera kumyanya ya AC igereranije 0, kwinjiza voltage gukata, kugeza insinga zishobora kugenzurwa zahujwe, nta voltage yinjira.

Ihame ni uguhindura inguni ya buri gice cya kabiri cyumuyaga uhinduranya kugirango uhindure imitsi ya sinusoidal, bityo uhindure agaciro keza k'umuyaga uhindagurika, kugirango ugere ku ntego yo gucogora.

Ibyiza:

insinga zoroshye, igiciro gito, guhuza neza neza, gukora neza, ingano nto, uburemere bworoshye, hamwe no kugenzura byoroshye.Yiganje ku isoko, kandi ibicuruzwa byinshi mubakora ni ubu bwoko bwa dimmer.

Ibibi:

imikorere idahwitse, mubisanzwe bivamo kugabanuka kurwego rwo kugabanuka, kandi bizatera umutwaro muto usabwa kurenza imbaraga zapimwe zingana cyangwa umubare muto wamatara yamatara ya LED, guhuza n'imihindagurikire mike.

2.gukata impande zose (RPC) MOS tube dimming

Inzira-yicyiciro-igabanya igenzura ryakozwe hamwe na tristoriste yumurima (FET) cyangwa ibikoresho bya bipolar transistor (IGBT).Kugenda kuruhande rwa feri yaciwe muri rusange ikoresha MOSFETs nkibikoresho byo guhinduranya, bityo bakitwa kandi MOSFET dimmers, bakunze kwita "MOS tubes".MOSFET ni igenzura ryuzuye, rishobora kugenzurwa kugirango rifungure cyangwa rizimye, ntakintu rero cyerekana ko dimmer ya thyristor idashobora kuzimwa burundu.

Byongeye kandi, MOSFET dimming umuzunguruko irakwiriye cyane kubushobozi bwa capacitive load dimming kurusha thyristor, ariko kubera igiciro cyinshi hamwe numuzunguruko ugereranije ugereranije, ntabwo byoroshye guhagarara neza, kuburyo uburyo bwa MOS tube dimming butigeze butezwa imbere. , hamwe na Dimmers ya SCR iracyafite umubare munini wamasoko ya dimingi.

3.0-10V DC

0-10V dimming nayo yitwa 0-10V signal dimming, nuburyo bwo kugereranya.Itandukaniro ryayo na FPC nuko hariho izindi ebyiri ebyiri 0-10V (+ 10V na -10V) kumashanyarazi 0-10V.Igenzura ibyasohotse mumashanyarazi muguhindura 0-10V voltage.Dimming iragerwaho.Nibyiza cyane iyo ari 10V, kandi birahagarara iyo ari 0V.Kandi 1-10V ni dimmer gusa ni 1-10V, mugihe dimmer yo kurwanya ihinduwe kugeza byibuze 1V, ibisohoka ni 10%, niba ibyasohotse ari 100% kuri 10V, umucyo nawo uzaba 100%.Birakwiye ko tumenya kandi ikintu cyiza cyo gutandukanya nuko 1-10V idafite imikorere ya switch, kandi itara ntirishobora guhinduka kurwego rwo hasi, mugihe 0-10V ifite imikorere ya switch.

Ibyiza:

Ingaruka nziza ya dimming, ihuza cyane, isobanutse neza, imikorere ihenze cyane

Ibibi:

insinga zitoroshye (insinga zikeneye kongera imirongo yerekana ibimenyetso)

4. DALI (Imigaragarire ya Digital Aderesi Yumucyo)

Igipimo cya DALI cyasobanuye umuyoboro wa DALI, harimo ntarengwa 64 (hamwe na aderesi yigenga), amatsinda 16 hamwe na 16.Ibice bitandukanye byo kumurika kuri bisi ya DALI birashobora guhurizwa hamwe kugirango bigenzurwe no gucunga ibintu bitandukanye.Mu myitozo, porogaramu isanzwe ya DALI irashobora kugenzura amatara 40-50, ashobora kugabanywamo amatsinda 16, mugihe ushobora gutunganya igenzura / amashusho amwe.

Ibyiza:

Kugabanuka neza, itara rimwe no kugenzura kimwe, itumanaho ryuburyo bubiri, byoroshye kubaza mugihe no gusobanukirwa ibikoresho nibikoresho namakuru.Ubushobozi bukomeye bwo kurwanya kwivanga Hariho protocole n'amabwiriza yihariye, byongera imikoranire yibicuruzwa hagati yibirango bitandukanye, kandi buri gikoresho cya DALI gifite kode yihariye ya adresse, ishobora rwose kugera kumucyo umwe.

Ibibi:

igiciro cyinshi hamwe no gukemura ibibazo

5. DMX512 (cyangwa DMX)

Moderi ya DMX ni impfunyapfunyo ya Digital Multiple X, bivuze kohereza amakuru menshi.Izina ryayo ryemewe ni DMX512-A, kandi interineti imwe irashobora guhuza imiyoboro igera kuri 512, mubyukuri rero dushobora kumenya ko iki gikoresho ari igikoresho cyo gukwirakwiza ibyuma bifata ibyuma bifata imiyoboro ya 512.Nibikoresho byuzuzanya bitandukanya ibimenyetso byo kugenzura nkumucyo, itandukaniro, na chromaticité, kandi bikabitandukanya ukundi.Muguhindura digitale potentiometero, igereranya risohoka urwego agaciro kahinduwe kugirango ugenzure umucyo na hue yikimenyetso cya videwo.Igabanya urumuri urwego 256 kuva 0 kugeza 100%.Sisitemu yo kugenzura irashobora kumenya R, G, B, 256 ubwoko bwimyenda yurwego, kandi mubyukuri ikamenya ibara ryuzuye.

Kubikorwa byinshi byubwubatsi, birakenewe gusa gushiraho umuto muto wo kugenzura mugisanduku cyo kugabura hejuru yinzu, mbere yo gutangiza gahunda yo kugenzura amatara, kubibika mu ikarita ya SD, hanyuma ukabishyira mubikoresho bito bigenzura hejuru yinzu. Kumenya Sisitemu.Kugenzura.

Ibyiza:

Kugabanuka neza, ingaruka zikungahaye

Ibibi:

Gukoresha insinga zigoye hamwe no kwandika aderesi, gukemura ibibazo

Dufite ubuhanga mu matara yaka, niba ushaka kumenya byinshi kubyerekeye amatara n'amatara, cyangwa kugura dimmer zigaragara muri videwo, nyamunekatwandikire.
