Dab tsi ntawm Dimmers muaj?

Dimmers tuaj yeem raug cais los ntawm kev tswj hwm txoj kev thiab daim ntawv thov.Raws li txoj kev tswj hwm, nws tuaj yeem muab faib ua qhov tsis kam dimmer, voltage regulation dimmer, magnetic amplifier reactance dimmer thiab hluav taws xob dimmer; thiab nruab hnub nrig integrated tswj system.

Qhov tsis kam dimmer txuas qhov tsis kam nyob rau hauv series ntawm lub teeb incandescent thiab cov khoom siv hluav taws xob, thiab hloov cov nqi kuj tuaj yeem kho qhov tam sim no hauv lub teeb ci kom ua tiav lub hom phiaj ntawm dimming. Nws qhov tsis zoo yog kev siv hluav taws xob siab, kev ua haujlwm qis, qhov loj me, thiab kev tswj tsis tau zoo. Qhov zoo yog tias ob qho tib si AC thiab DC fais fab tuaj yeem siv tau, thiab tsis muaj xov tooj cua cuam tshuam. Nws tuaj yeem siv tau rau hauv cov teeb pom kev ntawm cov chaw kuaj mob, kev ua yeeb yam suab paj nruag thiab cov khoom siv hauv nkoj navigation.

Lub voltage regulator dimmer yog autotransformer. Qhov thib ob qhov hluav taws xob hloov pauv los ntawm kev kho qhov chaw sib cuag ntawm tus txhuam hniav nrog lub coil qhov txhab sab nraud ntawm lub tshuab hluav taws xob yoke. Nws muaj qhov zoo ntawm kev siv hluav taws xob tsawg, kev ua haujlwm siab, thiab ua kom lub nra ntawm lub zog ntsuas tsis cuam tshuam rau qhov qub dimming degree. Qhov tsis zoo yog tias nws tsuas yog tsim nyog rau AC lub zog, hnyav, tsis muaj ferrous thiab ferrous hlau uas haus ntau dua, thiab tsis tuaj yeem tswj tau nyob deb.

Qhov sib nqus amplification reactance dimmer hloov qhov inductive reactance ntawm AC winding los ntawm kev hloov qhov loj ntawm qhov tam sim no hauv DC winding qhov txhab ntawm lub yoke hlau. Nws muaj qhov zoo dimming kev ua tau zoo thiab tswj tau yooj yim, tab sis yog loj thiab loj thiab tau hloov los ntawm hluav taws xob dimmers.

Electronic dimmer

Thaum ntxov, thyristors tau siv los ua cov khoom hloov, thiab tom qab ntawd thyristors tau siv. Qhov dimmer no muaj qhov zoo ntawm lub teeb yuag, me me, kev ua haujlwm siab, thiab kev tswj xyuas chaw taws teeb yooj yim, thiab siv dav. Nws qhov tsis zoo yog tias tsis muaj kev lim dej zoo, kev cuam tshuam hauv xov tooj cua yuav tshwm sim, thiab qhov dimming yog teeb meem rau cov pa tawm hluav taws xob xws li cov teeb fluorescent thiab cov roj teeb hluav taws xob siab. Dimmers siv high-power transistors lossis FETs tuaj yeem kov yeej qhov tsis txaus no.

Civil dimmer

Rau tsev, chaw ua haujlwm, chav sib tham, tsev kawm ntawv, txoj kev hauv tsev thiab lwm lub sijhawm. Cov kab yog qhov yooj yim, tus nqi qis, thiab kev ua haujlwm yuav tsum tsis siab. Cov dimmers xws li rooj teeb thiab chandeliers tuaj yeem ua tau raws li cov neeg xav tau ntawm lub teeb hauv kev ua haujlwm sib txawv, thiab ua tiav lub hom phiaj ntawm kev nplij siab, kev nyiam huv thiab kev txuag hluav taws xob.

Zaj duab xis thiab TV theem dimmer

Muaj ob hom ntawm ib lub voj voog thiab ntau lub voj voog, thiab txhua lub voj voog muaj peev xwm loj dua. Nws tseem yog hu ua dimming ntaus ntawv nrog ntau lub voj voog, muaj peev xwm loj, thiab ua ib qho system. Nws yog tus cwj pwm los ntawm ntau lub voj voog, ua tiav kev ua haujlwm, thiab kev ua haujlwm dimming zoo ib yam ntawm txhua lub voj voog. Muaj ob txoj kev tswj hwm: tswj kev tswj hwm thiab microcomputer tswj. Kev tswj cov txheej txheem suav nrog kev tswj tsis siv neeg, kev tswj hwm hauv nruab nrab, kev tswj tus ntoo khaub lig, kev tswj hwm tus tswv, kev tswj hwm tus tswv, thiab kev xaiv ua ntej ntawm scenes, thiab lwm yam.; Ntxiv rau tag nrho cov haujlwm uas tau hais los saum toj no, lub khoos phis tawj tswj hwm kuj tuaj yeem tswj cov theem teeb pom kev zoo raws li qhov sib txawv scenes thiab qhov kev txiav txim ntawm lub sijhawm. Cov ntaub ntawv lub teeb thiab tsaus yog khaws cia rau hauv microcomputer, thiab qhov kev zov me nyuam tau txiav txim siab raws li qhov sib lawv liag. Raws li cov kev cai tshwj xeeb ntawm cov yeeb yaj kiab thiab TV theem rau teeb pom kev zoo, ntau yam tshiab xws li lub suab tswj thiab kev tswj cov dimmers tau tshwm sim. Lub tshav dav hlau lub teeb dimmer yog ib qho khoom siv rau kev kho qhov ci ntawm lub tshav dav hlau siv lub teeb thiab cov teeb pom kev zoo ntawm cov tshav dav hlau. Nyob rau hauv ntau yam huab cua puag ncig, lub tshav dav hlau teeb yuav tsum muaj peev xwm coj kev tawm mus thiab tsaws ntawm lub dav hlau, thiab lub dimmer yuav tsum ua kom tau raws li qhov yuav tsum tau hloov ntawm qhov ci ntsa iab uas tau teev tseg hauv "International Civil Aviation Convention". Lub teeb pom kev ua tiav ntawm lub tshav dav hlau tau teeb tsa hauv ntau qhov loj thiab muaj qhov sib kis tau ntev. Qhov yuav tsum tau muaj kev ci ntsa iab tsis tuaj yeem cuam tshuam los ntawm lub zog hluav taws xob hluav taws xob, kev thauj khoom (nrog rau qhov kub hnyiab ntawm ib tus neeg lub teeb) thiab qhov ntev ntawm txoj kab, thiab tuaj yeem tswj tau hauv nruab nrab ntawm tus pej thuam. Yog li ntawd, lub tshav dav hlau lub teeb dimmer yog qhov tam sim no-kho qhov tsis tu ncua-tam sim no dimmer uas outputs high voltage. Txhua qhov teeb pom kev zoo txuas nrog rau theem nrab ntawm nws tus kheej kev rho tawm transformer, thiab tom qab ntawd lub hauv paus yog txuas nrog hauv series mus rau high-voltage output davhlau ya nyob twg ntawm lub dimmer, thiab cov zis tam sim no ntawm cov zis davhlau ya nyob twg yog kho kom ua tiav lub hom phiaj ntawm dimming.

Hnub ci kev tswj hwm qhov system yog qhov tsis siv neeg dimming system nrog microcomputer system. Nws yog siv los tswj lub hauv paus thiab tswj ntau lub teeb nyob rau hauv ntau lub chaw ua haujlwm lossis qhov chaw zoo sib xws hauv lub tsev, uas yog synchronized nrog kev siv lub hnub ci thiab muaj feem xyuam rau lub sijhawm ua haujlwm sab hauv tsev, thiaj li ua tiav lub hom phiaj ntawm kev ua haujlwm tsis muaj neeg siv thiab txuag hluav taws xob. . Nws siv photoelectric tswj, lub sijhawm ua haujlwm thiab tshuab computer los tswj lub teeb pom kev sab hauv tsev ntawm qib yuav tsum tau ua. Lub kaw lus muaj xws li nruab hnub nrig dimming, lub sij hawm program tswj dimming thiab tswb tswj dimming. Feem ntau ntawm cov dimmer loads yog incandescent teeb, thiab ob peb yog fluorescent teeb.
