Nigute ushobora kongera urumuri rwamatara ya LED?

LED (Light Emitting Diode) nisoko isanzwe yumucyo hamwe nibyiza byo gukora neza, kwizerwa no kuramba. Mubisabwa byinshi, dukeneye kenshi kugenzura urumuri rwa LED dukurikije ibikenewe. Iyi ngingo izerekana uburyo bumwe busanzwe bwa LED bwo kugenzura umucyo n'amahame yabo.

1. Hindura ikigezweho

Guhindura imiyoboro nimwe muburyo bworoshye bwo guhindura umucyo wa LED uhindura umuyaga unyuze. Umuyoboro munini uzatuma LED imurika, mugihe umuyoboro muto uzatuma ucika intege. Ubu buryo bukora kumurongo woroshye wa LED kandi birashobora gushyirwa mubikorwa muguhindura isoko, rezistor, cyangwa umushoferi uriho.

2. Impinduka z'ubugari bwa pulse (PWM)

Impinduka z'ubugari (PWM) ni tekinoroji ikoreshwa cyane mugucunga urumuri rwa LED. PWM igenzura umucyo muguhindura ubugari bwa pulse ninshuro za LED. Ihame ryayo ni uguhindura igipimo cyurwego rwo hejuru nurwego rwo hasi rwa pulse muri buri cyiciro, bityo bigereranya ingaruka zumucyo utandukanye. Ugereranije no guhindura ibigezweho, PWM irashobora kugera kumurongo wo hejuru wo guhindura neza no gukoresha ingufu nke.

3. Koresha résistoriste ihinduka

Impinduka irwanya (nka potentiometero) nikintu gisanzwe gikoreshwa mugucunga urumuri rwa LED. Muguhuza ristoriste ihindagurika kumurongo wa LED, umucyo urashobora kugenzurwa muguhindura imigendekere yimikorere muguhindura imyigaragambyo. Guhindura ukurwanya kwa résistoriste birashobora guhindura urumuri rwa LED mu buryo bwimbitse, ariko urwego rwacyo rushobora kuba ruto.

4. Koresha isoko ihoraho

Umuyoboro uhoraho uturuka kumurongo nuburyo busanzwe bwo gutwara LED, ihindura umucyo muguhindura ikigezweho cyamasoko ahoraho. Inkomoko ihoraho irashobora gutanga imiyoboro ihamye kugirango igumane urumuri rwa LED. Ubu buryo burakwiriye mubisabwa bisaba kugenzura neza urumuri rwa LED kandi bisaba gutuza.

5. Koresha chip igenzura

Amashanyarazi yihariye ya LED afite imikorere yo kugenzura urumuri rushobora guhindura urumuri binyuze mubimenyetso byo kugenzura hanze (nka PWM yinjiza). Iyi chip ihuza urumuri rwoguhindura imirongo kugirango igere neza neza. Gukoresha iyi chip byoroshya igishushanyo mbonera kandi gitanga uburyo bworoshye bwo kugenzura.

Mu ncamake, hari amahitamo menshi yo kugenzura urumuri rwa LED, harimo guhindura ibiyobora, ubugari bwa pulse modulasiyo, ukoresheje rezistoriste ihindagurika, amasoko ahoraho hamwe nubushakashatsi bugenzura. Buri buryo bufite uburyo bukurikizwa. Guhitamo uburyo bukwiye ukurikije ibikenewe byihariye birashobora kugera kuri LED igenzura yujuje ibisabwa.
