nigute umushoferi ayoboye akora?

Umushoferi udacogora ni igikoresho gikoreshwa muguhindura urumuri cyangwa ubukana bwa diode itanga urumuri (LED). Ihindura ingufu z'amashanyarazi zitangwa kuri LED, zemerera abakiriya guhitamo urumuri rwumucyo kubyo bakunda. Abashoferi badakunze gukoreshwa mugutanga urumuri rutandukanye hamwe nuburyo bwiza mumazu, mubiro, no murugo nokumurika hanzePorogaramu.

Dimmable LED abashoferi bakunze gukoresha Pulse Width Modulation (PWM) cyangwa Analog Dimming. Hano haribintu byihuse byerekana uburyo buri buryo bukora:

PWM: Muri ubu buhanga, umushoferi wa LED ahindura byihuse urumuri rwa LED kuri no kuzimya kuri radiyo ndende cyane. Microprocessor cyangwa sisitemu ya sisitemu igenzura guhinduranya. Kugirango ugere kumurongo ukwiye, urwego rwinshingano, rugaragaza igipimo cyigihe LED iri kuri off, irahindurwa. Inshingano yo hejuru itanga urumuri rwinshi, mugihe urwego rwo hasi rwinshingano rugabanya umucyo. Guhindura inshuro byihuse kuburyo ijisho ryumuntu ryumva urumuri rukomeza nubwo LED ihora ikingura kandi ikazimya.

Ubu buryo, bukoreshwa kenshi muri sisitemu ya dimming sisitemu, butanga kugenzura neza ibyasohotse mumucyo.

Analog Dimming: Guhindura urumuri, ingano yumuyaga unyura muri LED irahindurwa. Ibi bigerwaho muguhindura voltage ikoreshwa kuri shoferi cyangwa muguhindura amashanyarazi hamwe na potentiometero. Analog dimming itanga ingaruka nziza yo kugabanuka ariko ifite intera iri munsi ya PWM. Nibisanzwe muri sisitemu ishaje ya dimingi na retrofits aho guhuza dimming ari ikibazo.

Ubwo buryo bwombi bushobora kugenzurwa na protocole zitandukanye zijimye, harimo 0-10V, DALI, DMX, hamwe nuburyo butemewe nka Zigbee cyangwa Wi-Fi. Isohora rya protocole hamwe na shoferi kugirango wohereze ikimenyetso cyo kugenzura gihindura ubukana bwa dimingi mugusubiza ibyinjijwe nabakoresha.

Nibyingenzi kwibuka ko abashoferi ba LED badahinduka bagomba kuba bahujwe na sisitemu ya dimingi ikoreshwa, kandi umushoferi na dimmer bihuza bigomba kugenzurwa kugirango bikore neza.

Twandikirekandi dushobora gusangira amakuru menshi yerekeye amatara ya LED.
