Ibintu bitatu bikunze kunanirwa kumatara ya LED n'ibisubizo

Inshuti zimwe zibaza impamvu zisanzwe hamwe nuburyo bwo kuvura amatara yerekana ibimenyetso bya LED yaka, kandi abantu bamwe bashaka kubaza impamvu itara rya LED ridacana.Bigenda bite?Mubyukuri, haribintu bitatu byananiranye nibisubizo byamatara yerekana ibimenyetso.

Ibintu bitatu bikunze kunanirwa kumatara ya LED n'ibisubizo:

Ikosa risanzwe ni kunanirwa gukosora.Jya mu mucyo Umujyi ugure imwe uyisimbuze.Indongozi yose yangiritse gake.

Babiri.Yayoboye ibimenyetso byerekana urumuri:

1 phenomenon, niba ikigezweho ari kinini cyane, amasaro yamatara ntashobora kwihanganira switch.Mugihe gikomeye, insinga za zahabu cyangwa umuringa imbere yamasaro zirashobora gutwikwa, bigatuma amasaro adakora.

2. Amashanyarazi ya disiki arashobora kwangirika, mugihe uzayasimbuza andi mashanyarazi meza, ntabwo azahumbya.

3. Niba umushoferi afite umurimo wo kurinda ubushyuhe burenze, imikorere yo gukwirakwiza ubushyuhe bwamatara ya LED yerekana ibimenyetso ntishobora kubahiriza ibisabwa, kandi kurinda ubushyuhe burenze urugero bwumushoferi bizahita bihita bitangiye gukora.Kurugero, inzu ya 20 w projection itara ikoreshwa muguteranya amatara 30W ntabwo ikora akazi keza ko gukonja.

4. Niba amatara yo hanze nayo afite ibintu bya stroboscopique, bivuze ko amatara yuzuye.Nkigisubizo, niba gihumye, ntigicana.Itara n'umushoferi baravunitse.Niba umushoferi akora akazi keza ko kwirinda amazi, isaro ryamatara riravunika kandi isoko yumucyo irashobora guhinduka.

Bitatu.Gutunganya ibimenyetso byerekana ibimenyetso byerekana urumuri:

1. Muri off-line-power-LED yamashanyarazi ikoreshwa, imbaraga rusange topologiya ni topologiya yihariye.Icyatsi kibisi, 8W itari kumurongo wa LED, yujuje ingufu Inyenyeri ikomeye-yamurika.Mugihe cyogushushanya, kubera ko sinusoidal kwaduka kwamashanyarazi ihinduranya ya flake igenzura ntabwo itanga ingufu zihoraho kubogama kwambere, imbaraga zikora-moteri yumuzingi irashobora gukora kandi igatera urumuri.Kugira ngo wirinde iki kibazo, birakenewe ko habaho gusohora ibanze muri buri gice cyinzira.Kubwibyo, birakenewe guhitamo neza ubushobozi nubushobozi bwo kurwanya amatara ya LED yerekana amatara.

2. Mubisanzwe ijisho ryumuntu rirashobora kubona urumuri rwumucyo kuri Hz 70 Hz, ariko hejuru yibyo ntibishobora.Kubwibyo, mumashanyarazi yayoboye, niba ibimenyetso bya pulse bifite ibice bito bifite numurongo uri munsi ya 70 Hz, ijisho ryumuntu rizumva rihindagurika.Byumvikane ko, hari ibintu byinshi bishobora gutera amatara ya LED guhumbya muri porogaramu runaka.

3. Akayunguruzo ka Emi karasabwa no mubiyobora porogaramu zitanga imbaraga nziza zo gukosora no gushyigikira dimingi ya terefegitatu ya bi-cyerekezo ya SCR.Umuyoboro winzibacyuho uterwa nintambwe ya triterminal byerekezo ebyiri ya SCR ihindura rezonans naturel ya inductors na capacator muri emi muyunguruzi.

Niba resonance iranga itera iyinjiza iri munsi kurenza gufata ibintu bitatu-bi-icyerekezo cya SCR ihindura ibintu, ibice bitatu-bi-byerekezo bya SCR ihinduka bizimya.Nyuma yo gutinda gato, ibice bitatu-byerekezo byerekanwa bya SCR byo guhinduranya ibintu bizongera gufungura kugirango bishimishe resonance imwe.Uru ruhererekane rwibyabaye rushobora gusubirwamo inshuro nyinshi mugice cyakabiri cyumurongo wa INPUT wamashanyarazi ya LED semaphore, bigatuma LED igaragara.
