Ma LED anozivikanwa nekuderera kwekushandisa simba uye kupenya kwakanyanya.Kupenya uye kushandiswa kwesimba kunopfuura 60% kwakasiyana kubva kune echinyakare tungsten bulbs.Asi haasi ese ma bulbs anodzima, uye mutengo wemagirobhu anodzima uchadhura, iwe unozofanirwa kuongorora zvaunoda usati wasarudza mwenje wako we LED.Izvi zvinonyanya kukosha kana uchitsiva mwenje wekare neiyo nyowani LED tekinoroji kekutanga uye tarisira kuti vadzime.
Magirobhu angu eEdison anodzima here?
A dimmable light girobhu igirobhu remwenje rinokwanisa kugadzirisa kupenya kwechiedza zvinoenderana nezvinodiwa nemutengi, zvichibva zvakanganisa kupenya kwechiedza chemukati uye kuburitsa kunze kwakasiyana mukati memamiriro ekunze.
Kana iwe wakatenga yakapedzwa LED fixture kana girobhu, tarisa kuti kurongedza kunotaura zvakananga kuti inodzima.Izvi zvinofanirwa kutaurwa mutsanangudzo kana hunyanzvi hwekugadzira mwenje.Kana iwe ukashandisa isingadzimike LED pane dimmer iwe unowana yakawanda kupenya uye kukuvadza girobhu, ichidzikamisa hupenyu hwayo.Chiratidzo chakafanana nechepazasi pane dzimwe nguva chinoshandiswa kuratidza mwenje unodzima, zvinosuruvarisa kuti hapana chaiyo chiratidzo chepasirese.
Kazhinji kana girobhu rinogona kudzimaidzwa rinogona kuonekwa pakaiswa girobhu, uye magirobhu emwenje anodzima anodhurawo pane asingadzimike.Dimmable light bulbs anogona kugadzirisa kupenya kwechiedza zvinoenderana nezvinodiwa nevatengi, nekudaro zvichikanganisa kupenya kwechiedza chemukati uye kuburitsa kunze kwakasiyana mukati memamiriro ekunze, kuchengetedza simba uye kuderedza kabhoni.Vatengi vakawanda vanowanzotenga magirobhu emwenje asingadzimike.
LED Edison bulb dimming musimboti:
Senge inogara iripo ikozvino sosi, ma LEDs anogara akadzima.Ikozvino inoyerera kuburikidza nemwenje we LED bead inosarudza kubuda kwechiedza".Kupenya kwavo kunogona kugadziridzwa nekudzora ikozvino inosimbisa ye semiconductor zvinhu layer yakasungirirwa kune substrate.Ma LED haana kufanana nechinyakare mwenje masosi, uye dimming haina kukanganisa Kushanda uye hupenyu hwema LEDs.Muchokwadi, dimming inogona kuderedza yavo tembiricha yekushandisa, nekudaro kuwedzera hupenyu hwema LED.Chero mudziyo we LED, kana uchizoitwa mutsivi wemwenje sosi kana mwenje we LED, unoda mutyairi kuti awane dimming.Nokuti ma LED ari Ndiyo yakaderera-voltage DC sosi, uye LED inoda mutyairi wemagetsi kuti ichinje AC kuva inoshandiswa uye inogadziriswa DC current.Vatyairi ava vakakamurwa kuva nzira nhatu dze dimming.
Mune pulse width modulation (PWM) mode, ikozvino kuburikidza ne LED inobatidzwa uye ichidzimwa pamhepo yakanyanya, "kazhinji zviuru zvenguva pasekondi", uye ikozvino kuburikidza ne LED yakaenzana nehuwandu hwehuwandu hwemazuva ano panguva. iyo LED switching kutenderera."Nekudzikisa simba-panguva ye LED, avhareji yemazuva ano kana inoshanda ikozvino inogona kuderedzwa, nekudaro kuderedza kupenya kwe LED.Kufanana nemagetsi echinyakare masosi, maLED anogona zvakare kudzikiswa nekudzikiswa kwazvino (CCR), kana analog dimming.CCR inochengeta chiedza chinobva kune chinoramba chiripo, asi dimming inowanikwa nekuderedza ukuru hwezvino."Chiedza chinobuda chakaenzana nechazvino kuburikidza nemudziyo we LED,"
Ose PWM neCCR ane zvakanakira nekuipira.PWM inonyanya kushandiswa uye ine yakafara dimming renji.Nekuti PWM dimming inoshandisa kukurumidza kubatika nekudzima, inoda zvakanyanya kuomarara uye zvinodhura zvemagetsi dhiraivha kuti ibudise mapurusi azvino ehurefu hwakakwana kudzivirira maziso evanhu kuti asaaona.flickering.Iyo CCR dimming nzira inoshanda zvakanyanya uye iri nyore, nekuti dhiraivha yainoda iri nyore uye yakachipa.Kusiyana nePWM, CCR haiburitse electromagnetic interference EMI inokonzerwa nepamusoro frequency switching.Nekudaro, CCR haina kukodzera kune maapplication uko iyo dimming inodiwa iri pasi pe10%."Pamvura yakadzika kwazvo, maLED haana kushanda nemazvo uye kubuda kwemwenje kwaive kusina kugadzikana.
LED Silicon inodzorwa inodzoreredza magetsi emagetsi yakashandiswa mukudzima kwemarambi eincandescent uye marambi ekuchengetedza simba kare, uye zvakare ndiyo inonyanya kushandiswa dimming nzira ye LED dimming.Silicon controlled rectifier imhando yekudzima kwemuviri.Nheyo yayo yekushanda ndeyekugadzira tangential inobuda voltage waveform mushure meiyo waveform yevoltage yekuisa yatemwa neiyo conduction angle.Kushandisa iyo tangential musimboti kunogona kuderedza kukosha kunoshanda kweiyo inobuda voltage, nekudaro ichidzikisa simba reyakajairika mutoro (resistive mutoro).Silicon controlled rectifier dimmers ine zvakanakira kurongeka kwepamusoro, kunyatsoshanda, diki saizi, huremu huremu, uye nyore kudzora kure.Chiedza chakagadziridzwa chakapfava uye chakagadzikana, uye hapazovi ne stroboscopic phenomenon.kutonga pamusika.Zvakanakira zveSilicon inodzorwa rectifier dimming ndeyekushanda kwepamusoro, kuita kwakagadzikana uye mutengo wakaderera.
Iwo matatu-nhanho dimming yezvigadzirwa zvedu zvinotora silicon inodzorwa inodzoreredza magetsi.
Mamiriro ekushandiswa kwegirobhu anodzima:
Dimmable light bulbs anoshandiswa munzvimbo dzakasiyana-siyana, dzakadai semahotera, madhanzi, nzvimbo, nzvimbo dzekuratidzira uye dzimwe nguva dzinoda kuvhenekera, kunyanya nekushandura huwandu hwechiedza chekugadzirisa kupenya kwechiedza.Iye zvino mhepo yave kudziya, nyaya yekuderedza kushandiswa kwemagetsi pakuvheneka yave pedyo zvakare.Neraki, kubuda kwemwenje ye LED kunochengetedza simba rakawanda.Zvingave zviri nani kana mutemo ungashandiswa kuchengetedza simba zvakanyanya.Nekuda kwekudzima kwema bulbs e LED, semarambi emadziro emba, mahofisi, zvitoro, zvikoro, mafekitori uye zvimwe zviitiko zvinogona kugadziriswa zvinoenderana nemwenje unodiwa, uye simba rekuchengetedza simba rinogona kuwanikwa.Kana zviitiko izvi zvikatsiviwa nezvinochinjika ma bulbs e LED, inochengetedza simba rakawanda.
Dimmable mwenje inokupa iwe kuchinjika kuenderana nemwenje wakakukomberedza kune chako chiitiko.Iwe unogona kuda chiedza chakajeka paunenge uchishanda pacheki asi chiedza chisina kujeka chinozorodza paunenge uchidya manheru.Dimming yakashandiswa zvakare zvakanyanya mukati
nzvimbo dzekutengeserana uye dzemaindasitiri.Kuwedzera mwenje unodzima kunopa kuchinjika kunzvimbo yako yehofisi uye inobvumira kuvhenekera kwakaringana kune zvaunofarira kana zvinodiwa nevashandi.Ungave uri kusangana nevaenzi, uchiona TV, uchiteerera mimhanzi, nemhuri yako, kana kufunga wega, unogona kugadzirisa kupenya kwezviedza zvakasiyana kuti ugadzire mhepo yakagadzikana, yakanyarara, inowirirana, uye inodziya, uye ruzivo rwakadzama rwehupenyu.Chiedza chakapfava chinogona kuunza hunhu hwakanaka, mwenje mudiki uye wakasviba unogona kubatsira kufunga, kuwanda uye kupenya kupenya kunogona kuita kuti mhepo iwedzere kudziya.Zvese zvinodikanwa zvinogoneka zvinogona kuitwa kuburikidza nekushanda kwakareruka, uye chete zvinoda kudzorwa neakajairika switch kuti agadzirise kupenya uye kwakasviba kupenya kwenzvimbo dzakasiyana.
