Mutyairi we LED anogona kudzimwa anoshanda sei?

Dhiraivha inodzimwa mudziyo unoshandiswa kushandura kupenya kana simba remwenje inoburitsa chiedza (LED). Inogadzirisa simba remagetsi rinopihwa kumaLED, zvichibvumira vatengi kugadzirisa kupenya kwechiedza sezvavanoda. Dhiraivha dzinodzimwa dzinowanzo shandiswa kugadzira kupenya kwakasiyana-siyana mudzimba, mumahofisi, uye mune dzimwe nzvimbo dzemukati nedzemukati.mwenje wekunzemafomu.

Madhiraivha e LED anodzimwa anowanzo shandisa Pulse Width Modulation (PWM) kana Analog Dimming. Heino pfupiso yekushanda kwenzira imwe neimwe:

PWM: Munzira iyi, mutyairi we LED anochinja nekukurumidza magetsi e LED anobatidzwa nekudzima pa frequency yakakwira kwazvo. Microprocessor kana digital circuitry inodzora switching. Kuti uwane mwero wakakodzera wekupenya, duty cycle, iyo inoratidza huwandu hwenguva iyo LED iri kubatidzwa kana kudzima, inochinjwa. Duty cycle yakakwira inogadzira chiedza chakawanda, nepo duty cycle yakaderera inoderedza kupenya. Kuchinja frequency kunokurumidza zvekuti ziso remunhu rinoona kubuda kwechiedza kunoramba kuripo kunyangwe LED ichiramba ichibatidzwa nekudzima.

Maitiro aya, ayo anowanzo shandiswa muma digital dimming systems, anopa kutonga kwakakwana pamusoro pemagetsi anobuda.

Kudzikisa magetsi neAnalog: Kuti uchinje kupenya, huwandu hwemagetsi ari kuyerera kuburikidza nema LED hunogadziriswa. Izvi zvinoitwa nekugadzirisa voltage inoshandiswa kumutyairi kana nekugadzirisa magetsi ne potentiometer. Kudzikisa magetsi neanalog kunoita kuti magetsi adzikise magetsi zvakanaka asi ane mwero wakaderera wekudzikisa magetsi pane PWM. Kunowanikwa kakawanda mumasisitimu ekare ekudzikisa magetsi uye ma retrofits uko kuenderana kwemagetsi kuri dambudziko.

Maitiro ese ari maviri anogona kudzorwa nemaitiro akasiyana-siyana ekudzima magetsi, anosanganisira 0-10V, DALI, DMX, uye sarudzo dzewireless dzakadai seZigbee kana Wi-Fi. Maitiro aya anosangana nemutyairi kutumira chiratidzo chekudzora chinogadzirisa simba rekudzima magetsi zvichienderana nezvinoiswa nemushandisi.

Zvakakosha kuyeuka kuti madhiraivha e LED anodzimwa anofanira kunge anoenderana nesystem yekudzima iri kushandiswa, uye kuenderana kwedhiraivha nedhiraivha kunofanira kusimbiswa kuti kushande zvakanaka.
