mutyairi anodzima akatungamira anoshanda sei?

A dimmable driver mudziyo unoshandiswa kushandura kupenya kana kusimba kwemwenje-emitting diodes (LED) zvigadziriso zvemwenje.Inogadzirisa simba remagetsi rinopiwa kune LEDs, zvichiita kuti vatengi vagadzirise kupenya kwechiedza kune zvavanoda.Madhiraivha anodzima anowanzo shandiswa kugadzira kupenya kwakasiyana kusimba uye manzwiro mudzimba, mahofisi, uye zvimwe zvemukati uyechiedza chekunzeapplications.

Dimmable LED drivers vanowanzo shandisa Pulse Width Modulation (PWM) kana Analog Dimming.Heino rondedzero inokurumidza yekuti nzira yega yega inoshanda sei:

PWM: Muhunyanzvi uhu, mutyairi we LED anokurumidza kushandura iyo LED ikozvino nekudzima pamhepo yakanyanya.A microprocessor kana digital circuitry inodzora kuchinja.Kuti uwane chiyero chakakodzera chekupenya, kutenderera kwebasa, kunoratidza chikamu chenguva iyo LED iri payakasiyana nekudzima, inoshandurwa.Yepamusoro duty cycle inoburitsa chiedza chakawanda, nepo yakaderera duty cycle inoderedza kupenya.Iyo switching frequency inokurumidza zvekuti ziso remunhu rinoona kuenderera kwemwenje kubuda kunyangwe iyo LED inogara ichibatidza nekudzima.

Iyi nzira, iyo inowanzo shandiswa mumadhijitari dimming masisitimu, inopa kutonga chaiko pamusoro pekubuda kwechiedza.

Analog Dimming: Kushandura kupenya, huwandu hwezvino hunoyerera kuburikidza ne LED hunogadziriswa.Izvi zvinoitwa nekugadzirisa voltage inoshandiswa kumutyairi kana nekugadzirisa ikozvino ne potentiometer.Analog dimming inoburitsa yakatsetseka dimming maitiro asi ine yakaderera dimming renji pane PWM.Zvinowanzoitika mumasisitimu ekare dimming uye retrofits uko kuenderana kwe dimming iri nyaya.

Maitiro ese ari maviri anogona kudzorwa neakasiyana maprotocol, anosanganisira 0-10V, DALI, DMX, uye isina waya sarudzo seZigbee kana Wi-Fi.Aya maprotocol anopindirana nemutyairi kutumira chiratidzo chekudzora chinogadzirisa kuderera kwesimba mukupindura kupinza kwemushandisi.

Zvakakosha kuyeuka kuti madhiraivha e LED anodzikira anofanirwa kuenderana neiyo dimming system iri kushandiswa, uye kuenderana kwemutyairi uye dimmer kunofanirwa kusimbiswa kuti ishande nemazvo.

Taura nesuuye isu tinogona kugovera rumwe ruzivo nezve LED strip mwenje.
