Molao-motheo oa dimmer LED
LED dimmer ke karolo ea bohlokoa ea mabone a morao-rao, ke ka ho fetola boholo ba motlakase oa phepelo ea motlakase, ho lokisa khanya ea mabone a LED. Ka nts'etsopele e tsoelang pele le ntlafatso ea theknoloji ea mabone a LED, mabone a LED a fetohile lihlahisoa tse ka sehloohong tšimong ea mabone a ka hare le a ka ntle, kahoo tšebeliso ea li-dimmers tsa LED e behile litlhoko tse phahameng. Sehlooho sena se tla hlahisa molao-motheo oa LED dimmer le kamoo e sebetsang hammoho le mabone a LED ho utloisisa le ho sebelisa sesebelisoa sena hamolemo.
Molao-motheo oa dimmer LED
Molao-motheo oa dimmer ea LED ke ho fetola khanya ea tlhahiso ka ho fetola motlakase oa motlakase oa DC oa lebone. Kaha lebone la LED ke mohloli o otlolohileng oa motlakase o sebelisoang hona joale, hoa hlokahala ho fetola motlakase oa motlakase oa oona o tobileng nakong ea tšebeliso ho laola khanya ea mohloli oa leseli la LED.
Potoloho eaMabone a LEDe kenyelletsa likarolo tse tharo tsa mantlha, e leng phepelo ea motlakase, mohloli oa hona joale oa kamehla le mohloli oa lebone la LED ka bowona. Motlakase o fana ka matla a lekanang a ho khanna mohloli oa leseli la LED, ha mohloli o sa khaotseng oa hona joale o tiisa botsitso ba mohloli oa leseli la LED ka ho boloka motlakase o phallang ka LED o sa fetohe. Ka hona, mosebetsi o ka sehloohong oa dimmer ke ho lokisa motlakase oa phepelo ea matla, o amang khanya ea mohloli oa leseli la LED. Dimmer ka kakaretso ka mekhoa e meraro ea ho fihlela taolo ea motlakase oa phepelo ea matla a LED: ho feto-fetoha ha PWM, ho feto-fetoha ha motlakase le ho feto-fetoha ha hona joale kamehla.
1. Ho feto-fetoha ha molumo oa PWM
Ho feto-fetoha ha molumo oa PWM ke o mong oa mekhoa e sebelisoang haholo ea taolo ea dimmer ea LED. Mokhoa ona oa tokiso o fetola motlakase oa phepelo ea motlakase ka lebelo le itseng mme o laola sekhahla sa ts'ebetso ea motlakase oa phepelo ea motlakase potolohong e 'ngoe le e' ngoe, ka hona e ama ho khanya ha lebone la LED. Ho fifala ha matla ho ka fihlelleha ka ho feto-fetoha ha molumo oa PWM, hammoho le ho fihlela litlhoko tse fapaneng tsa mabone.
2. Mokhoa oa ho sebetsa oa tšebelisano-'moho pakeng tsaLeseli la LED le khanya ea LED
Mokhoa oa tšebelisano-'moho pakeng tsa LED dimmer le leseli la LED ke ho lemoha phetoho ea khanya ea leseli la LED ka ho sebelisana. Se latelang ke kenyelletso e khuts'oane ea tšebelisano lipakeng tsa dimmer ea LED le leseli la LED.
1. Ho feto-fetoha ha molumo oa PWM
Ka mokhoa oa ho feto-fetoha oa PWM, khanya ea leseli la LED e laoloa ka ho fetola potoloho ea mosebetsi oa motlakase oa phepelo ea matla. Dimmer e fetisetsa lets'oao la tokiso ho lebone la LED, 'me leseli la LED le hlahisa leseli le fapaneng ho latela khanya e fapaneng ea lets'oao la tokiso. Letšoao la tokiso lipakeng tsa tse peli hangata le ipapisitse le lets'oao la dijithale, le ka lemohang taolo ea hole le ho fifala.
2. Voltage modulation
Mokhoeng oa ho feto-fetoha ha motlakase, dimmer ea LED e laola lebone la LED ka ho khanna tlhahiso ea matla a lebone la LED.
