Jagoranci-baki dimming (jagoranci-baki lokaci-yanke dimming) da trailing-baki dimming (trailing-gefen lokaci-yanke dimming) su ne lokaci-ikon tushen dimming fasahar, da farko amfani da LED lighting da na gargajiya lighting tsarin.Below ne mai kwatanta bincike na biyu.dimmerfasaha:
1.Aikin Ka'ida
Dimming Baƙin Jagora:
Yanke wutar lantarki yana faruwa a farkon kowane rabin igiyar zagayowar AC (lokaci 0°). Ta hanyar jinkirta kunna lokacin tafiyar da thyristors (watau daidaita kusurwar gudanarwa), ana sarrafa ingantacciyar wutar lantarki a cikin kaya, ta haka ne ke daidaita haske. Misali, mafi girman jinkiri a cikin kusurwar jawo, gajeriyar lokacin gudanarwa, kuma ƙananan haske.
Dimming-Baƙi:
Yanke wutar lantarki yana faruwa kusa da ƙarshen kowane rabin igiyar zagayowar AC (lokaci 180°). Ta hanyar kashe MOSFETs ko IGBTs 'lokacin gudanarwa a baya, ana samun dimming. Misali, farkon lokacin kashewa, ƙananan ƙarfin ƙarfin lantarki, darage hasken.
2.Abubuwan da ake bukata
Dimming Baƙin Jagora:
Yana amfani da thyristors (SCR/Triac) azaman na'urori masu sauyawa, waɗanda na'urori masu sarrafawa ne kawai (suna iya sarrafa sarrafawa kawai, ba a kashe rayayye ba).
Dimming-Baƙi:
Yana amfani da MOSFETs ko IGBT azaman na'urori masu sauyawa, waɗanda na'urori ne masu cikakken sarrafawa (suna iya sarrafa duka sarrafawa da kashewa).
3. Kwatancen Ayyuka
| Siffar | Dimming mai jagora | Dimming-baki mai bin hanya |
| Rage Range | Fadi (amma maiyuwa ba za a kashe gabaɗaya ba a ƙaramin haske) | Dan kunkuntar, amma mafi kwanciyar hankali |
| Daidaituwa | Yana buƙatar daidaitawa tare da tsarin dimming thyristor kuma yana da ƙananan buƙatun kaya | Babu ƙaramin buƙatun kaya, dacewa da ƙananan na'urori masu ƙarfi |
| Flicker & Surutu | Mai yuwuwa ga tsangwama na lantarki da ƙananan mitoci | Karancin amo, slim dimming |
| Ƙarfin Kashewa | Zai iya barin rarraunawar halin yanzu (batun haske na LED) | Za a iya kashewa gabaɗaya, babu ragowar halin yanzu |
| Farashin & Matsala | Ƙananan farashi, da'ira mai sauƙi, mai jituwa tare da wayoyi na gargajiya | Babban farashi, hadaddun kewayawa |
4.Taƙaitaccen Ribobi da Fursunoni
Ribobi na Dimming-Bashi:
Ƙananan farashi, fasaha balagagge, mai dacewa da tsarin dimming thyristor (misali, incandescent na gargajiyadimmers).
Fursunoni na Dimming-Bashi:
Yana iya haifar da firgita LED, tsangwama na lantarki, kuma maiyuwa baya kashe gabaɗaya ƙarƙashin ƙananan kaya.
Ribobin Dimming-Baƙi:
Dimming dimming, babu flickering, yana goyan bayan kaya masu ƙarfi (misali, direbobin LED), kuma yana iya kashewa gabaɗaya.
Fursunoni Dimming-Baƙi:
Maɗaukakin farashi, ƙarancin shigar kasuwa, galibi ana amfani da shi don rage ƙarancin fitila ɗaya.
5.Application Scenarios
Dimming Baƙin Jagora:
Ya dace da ayyukan sake fasalin hasken wuta na gargajiya (misali, maye gurbin kwararan fitila) da tsarin hasken kasuwanci mai ƙarfi (dole ne ya cika mafi ƙarancin buƙatun kaya).
Dimming-Baƙi:
Ya dace da fitilun LED masu ƙarancin ƙarfi (misali, fitilun tebur, fitilun gida ɗaya) da yanayin yanayin da ke buƙatar ingancin dimming (misali, gidajen tarihi, otal).
6.Tsarin Ci gaban Fasaha
Dimming na gaba-gaba ya kasance rinjaye a kasuwa saboda fa'idar farashinsa, amma dimming-gefen dimming sannu a hankali yana samun karbuwa a cikin aikace-aikacen dimming masu inganci.Amma duka biyun suna buƙatar kula da daidaituwar direba, saboda haɗa su na iya haifar da gazawar lalacewa ko lalacewar na'urar.
7.Kammalawa
Dimming-baki mai jagora da dimming-baki kowanne yana da ribobi da fursunoni kuma sun dace da yanayin aikace-aikace daban-daban. Dimming-gefen jagora yana da tsada-tasiri kuma mai dacewa, yana mai da shi manufa don sake fasalin hasken al'ada da tsarin ƙarfi mai ƙarfi. Dimming-gefe yana ba da slim, dimming kyauta kuma ya dace da ƙarancin ƙarfi da madaidaicin buƙatun dimming. Yayin da fasaha ke ci gaba, aikace-aikacen dimming-gefen dimming a cikin madaidaicin filayen dimm zai ƙaru a hankali.
