Nigute icyumba cy'inama cyerekana LED cyerekanwa?

Reba niba insinga nimbaraga zamashanyarazi ya module ya mbere hamwe nibimenyetso bidasanzwe byerekana icyerekezo kiri muburyo bwiza. Umubare wamasomo ntushobora guhora ucanwa cyangwa ntusanzwe. Irashobora guhindurwa niba module iyobowe idashoboye gucana, byerekana ko ntamashanyarazi yinjiza. Baza ishami rishinzwe gutanga amashanyarazi cyangwa ukoreshe multimeter ya digitale kugirango ugenzure.

Niba module imwe itamurika, reba niba amashanyarazi yayo ahinduka akora neza. Niba birenze module imwe yerekana ibara ryimyitwarire no kudahuza, ibi birashobora guterwa namakuru mabi yerekana amakuru yoherejwe. Ibikurikira, reba niba amashanyarazi yamashanyarazi arekuye. Gusimbuza inkingi yageragejwe, gukurura no kongera gushyiramo umurongo. Urashobora gukora iperereza niba hari ikibazo hamwe na PCB ihuza ubuyobozi niba ikibazo kivutse mugihe uhinduye umurongo mwiza wa kabili.

Nigute ushobora kumenya neza ko itara ryonyine rizimye: Kumenya niba icyumba cy'inamaLED yerekanayavunitse, koresha igikoresho. Niba urumuri rwacitse, rusimbuze ukurikiza intambwe ya gatanu yanditse hano hepfo. Ubuhanga nyabwo bwo gupima amatara nugukoresha multimeter ya digitale mugice cya rezistor X1, guhuza icyiciro cyiza cyayobowe na digitale ya multimeter yumukara wa DC, hanyuma ugahuza icyiciro kibi na ammeter itukura DC. Amatara ya kalibibasi azakora niba ayoboye ari. niba itara ryaka Ntabwo ari urumuri rwiza cyane rwo gupima neza niba ruzimye.

Kutabungabunga LED (ingingo idashobora kugenzurwa): Ukurikije umwihariko, hitamo bumwe muburyo bukurikira bwo kubungabunga kugirango umenye imiterere yayoboye mugihe cyo gusuzuma itara rimwe. Kugira isuku mu maso: Inkinzo yo mumaso irashobora gukurwaho hamwe nicyuma gikwiranye. Subiza mask yo gukingira hanyuma usimbuze itara. Inama yumwimerereicyumba LED yerekana ecranisubirwamo iyo urumuri rumaze guhinduka kandi igisubizo cya colloidal gifunzwe. Kugirango ukore neza, komeza umugozi kuruhande rwinyuma. Kugirango ukore ibi, kura umugozi kuruhande rwinyuma kugirango uhagarike amashanyarazi hamwe numuyoboro wibimenyetso bya data, ukureho utabishaka module mumabati yicyuma, hanyuma wimuke kuruhande rwinyuma rwa chassis nkuru. tekinike yo kubungabunga mu maso.
