Ramangwana LED dimming system
Saka rudzii rwe dimming system inofanira kushandiswa ne LED?
4.1 PWM Dimming
Sezvambotaurwa, kudzima kwe LED kuri nani kushandisa PWM kudzima. Paunenge uchishandisa PWM dimming, unogona kuisa iri nyore PWM jenareta mumadziro switch, wobva washandisa potentiometer kudzora iyo PWM yebasa reshiyo kuti uwane kudzima. Asi kana iwe uchida kushandura mwenje uye kudzima, iwe unofanirwa kuwedzera peya yewaya. Nokudaro, hazvienderani nemutungamiri wekushandura thyristor mumadziro ekutanga. Iyo yepakutanga thyristor switch ine mbiri chete inotungamira, iyo inogona kudzikiswa uye kuchinjika. Kubatsira uku kwakaoma kuenderana. Zvisinei, chaizvoizvo, marambi anonyanya kushandiswa anoshandiswa kudzima mwenje wedhesiki kana marambi akamira. Iwo ma dimmer switch akaiswa patambo yemagetsi pachinzvimbo chemadziro, saka hazvina basa kushandisa maviri anotungamira mumadziro. Mune mamwe mazwi, PWM dimming inogona kuiswa zvakananga kune dimming tafura marambi.
