Hanyoyi Biyar Dimming Fitilolin LED

Don haske, dimming yana da mahimmanci.Dimming ba zai iya haifar da yanayi mai dadi kawai ba, amma kuma yana ƙara yawan amfani da hasken wuta. Bugu da ƙari, don hasken hasken LED, dimming ya fi sauƙi a gane fiye da sauran fitilun fitilu, fitilu masu ceton makamashi, fitilun sodium mai girma, da dai sauransu, don haka shi ya fi dacewa don ƙara ayyukan dimming zuwa nau'ikan fitilun LED iri-iri.Wadanne irin hanyoyin dimming fitilar ke da su?

1.Leading gefen lokaci yanke sarrafa dimming (FPC), kuma aka sani da SCR dimming

FCP ita ce ta yi amfani da wayoyi masu sarrafawa, farawa daga matsayin dangi na AC 0, tsinkewar wutar lantarki, har sai an haɗa wayoyi masu sarrafawa, babu shigarwar wutar lantarki.

Ka'idar ita ce daidaita kusurwar gudanarwa na kowane rabin-gizon na madaidaicin halin yanzu don canza siginar igiyoyin sinusoidal, ta haka ne ke canza ingantaccen darajar madaidaicin halin yanzu, don cimma manufar dimming.

Amfani:

wayoyi masu dacewa, ƙananan farashi, daidaitattun daidaitawa, babban inganci, ƙananan girman, nauyi mai haske, da sauƙi mai sauƙi.Ya mamaye kasuwa, kuma yawancin samfuran masana'antun sune irin wannan dimmer.

Rashin hasara:

ƙarancin ƙarancin ƙarancin aiki, yawanci yana haifar da raguwar kewayon dimming, kuma zai haifar da mafi ƙarancin nauyin da ake buƙata ya wuce ƙarfin ƙididdigewa ɗaya ko ƙarami na fitilun fitilu na LED, ƙarancin daidaitawa da ƙarancin dacewa.

2.trailing baki yanke (RPC) MOS tube dimming

Dimmers masu sarrafa matakin-yanke-gefen da aka yi tare da transistor tasirin filin (FET) ko na'urorin transistor bipolar-ƙofa (IGBT).Dimmers masu yanke-tsaye gabaɗaya suna amfani da MOSFETs azaman na'urori masu sauyawa, don haka ana kiran su MOSFET dimmers, wanda akafi sani da "MOS tubes".MOSFET na'ura ce mai cikakken sarrafawa, wanda za'a iya sarrafa shi don kunnawa ko kashewa, don haka babu wani al'amari da ba zai iya kashe thyristor dimmer gaba ɗaya ba.

Bugu da kari, da'irar dimming MOSFET ta fi dacewa da dimming capacitive load fiye da thyristor, amma saboda tsadar tsada da kuma ingantacciyar da'irar dimming, ba shi da sauƙi a tsaya tsayin daka, ta yadda tsarin dimming na MOS ba a samar da shi ba. , kuma SCR Dimmers har yanzu suna lissafin mafi yawan kasuwar tsarin dimming.

3.0-10V DC

Dimming 0-10V kuma ana kiransa 0-10V siginar dimming, wanda shine hanyar dimming analog.Bambancinsa da FPC shine cewa akwai ƙarin musaya 0-10V guda biyu (+10V da -10V) akan wutar lantarki na 0-10V.Yana sarrafa abin da ake fitarwa na wutar lantarki ta hanyar canza ƙarfin lantarki na 0-10V.Ana samun dimming.Yana da haske idan yana da 10V, kuma yana kashewa lokacin da yake 0V.Kuma 1-10V kawai dimmer shine 1-10V, lokacin da aka daidaita dimmer na juriya zuwa mafi ƙarancin 1V, abin da ake fitarwa yanzu shine 10%, idan fitarwa na yanzu shine 100% a 10V, haske kuma zai zama 100%.Yana da mahimmanci a lura kuma mafi kyawun abin da za a bambanta shi ne cewa 1-10V ba shi da aikin sauyawa, kuma ba za a iya daidaita fitilar zuwa matakin mafi ƙasƙanci ba, yayin da 0-10V yana da aikin sauyawa.

4. DALI (Digital Addressable Lighting Interface)

Ma'aunin DALI ya ayyana hanyar sadarwar DALI, gami da matsakaicin raka'a 64 (tare da adireshi masu zaman kansu), ƙungiyoyi 16 da fage 16.Raka'o'in haske daban-daban akan bas ɗin DALI ana iya haɗa su cikin sassauƙa don fahimtar sarrafawa da sarrafa fage daban-daban.A aikace, aikace-aikacen tsarin DALI na yau da kullun na iya sarrafa fitilu 40-50, waɗanda za'a iya raba su zuwa ƙungiyoyi 16, yayin da suke iya aiwatar da wasu sarrafawa/muhalli a layi daya.

Amfani:

Madaidaicin dimming, fitila ɗaya da sarrafawa ɗaya, sadarwa ta hanyoyi biyu, dacewa don tambaya mai dacewa da fahimtar matsayin kayan aiki da bayanai.Kyakkyawan iyawa da anti-tsangwama akwai yarjejeniya ta musamman da ka'idoji, wanda ke inganta aikin intrandoes tsakanin samfurori daban-daban, da kuma na'urar Dali tana da lambar adireshin daban.

5. DMX512 (ko DMX)

DMX modulator shine taƙaitaccen Digital Multiple X, wanda ke nufin watsa dijital da yawa.Sunan hukuma shine DMX512-A, kuma guda ɗaya na iya haɗawa har zuwa tashoshi 512, don haka a zahiri zamu iya sanin cewa wannan na'urar na'urar dimming ce ta dijital tare da tashoshi 512 dimming.Haɗaɗɗen guntu na kewayawa wanda ke raba siginar sarrafawa kamar haske, bambanci, da chromaticity, da sarrafa su daban.Ta hanyar daidaita potentiometer na dijital, ana canza ƙimar matakin fitarwa na analog don sarrafa haske da launin siginar bidiyo.Yana raba matakin haske zuwa matakan 256 daga 0 zuwa 100%.Tsarin sarrafawa na iya gane R, G, B, nau'ikan matakan launin toka 256, kuma da gaske gane cikakken launi.

Don aikace-aikacen injiniya da yawa, kawai ya zama dole don saita ƙaramin mai sarrafawa a cikin akwatin rarrabawa a kan rufin, riga-kafi shirye-shiryen tsarin kula da hasken wuta, adana shi a cikin katin SD, kuma saka shi cikin ƙaramin runduna mai sarrafawa a kan rufin. don gane tsarin hasken wuta.Ikon dimming.
