LED yerekana ecran iramenyerewe cyane mubuzima kandi izana ibintu byinshi byoroshye mubuzima bwacu.Kubera ko urumuri rwa LED yerekana ecran idashobora guhinduka hamwe nurumuri rwibidukikije, hariho ikibazo cyo kwerekana bidasobanutse kumanywa cyangwa kumurika nijoro kubera kuba mwinshi cyane.Niba umucyo ushobora kugenzurwa, ntabwo imbaraga zishobora gukizwa gusa, ahubwo ningaruka zo kwerekana ecran yerekana irashobora gukorwa neza.
01led ni urumuri rwicyatsi kibisi, inyungu nyamukuru ni urumuri rwiza
Hamwe niterambere niterambere ryubumenyi bwibintu, imikorere yumucyo izanozwa cyane mumyaka 10 iri imbere;gukoresha ingufu nke, ubuzima bumara igihe kirekire, ibikoresho bisubirwamo, kandi nta kwanduza ibidukikije.Nubwo igihugu cyacu cyatangiye bitinze, mumyaka yashize nacyo cyatangiye ubushakashatsi niterambere, politiki yinganda ninkunga.Ugereranije n’itara ryaka, LED ifite itandukaniro rinini: umucyo wumucyo ahanini ugereranije nubunini bwimbere yimbere inyura muri diode itanga urumuri.Ukoresheje iyi miterere, urumuri rwibidukikije rupimwa na sensor optique, urumuri rumurika ruhinduka ukurikije agaciro gapimwe, kandi ingaruka zimpinduka zumucyo wibidukikije bikomeza, kandi ubwubatsi butuma abantu bakora bishimye.Ibi ntibirema gusa ibidukikije byiza bifite umucyo uhoraho, ahubwo binakoresha byuzuye urumuri rusanzwe kandi bizigama ingufu cyane.Kubwibyo, ubushakashatsi kuri tekinoroji ya LED ihuza imiterere ningirakamaro cyane.
02 amahame shingiro
Igishushanyo gikoresha inkingi kugirango wohereze amakuru hamwe nuburyo bwo gusikana kugirango umenye LED yerekana inyandiko cyangwa ishusho.Ubu buryo bwahujwe nu byuma byumuzunguruko kugirango ugere ku ntego yo kugereranya muri rusange urumuri rwerekana.Koresha ibyiyumvo biranga fotorezistor kumucyo wibidukikije, gukusanya impinduka zumucyo wibidukikije, kuyihindura mubimenyetso byamashanyarazi hanyuma ubyohereze kuri microcomputer imwe, chip imwe itunganya ibimenyetso, kandi igenzura igipimo cyinshingano zumusaruro Umuyoboro wa PWM ukurikije amategeko runaka.Umuyoboro wa voltage uhinduranya umuzunguruko wongeyeho hagati ya microcomputer imwe-imwe hamwe na ecran yerekanwe kugirango tumenye ihinduka ryerekanwa rya ecran yerekana na microcomputer imwe.Umuyoboro wa PWM wahinduwe ukoreshwa mugucunga imiyoboro ya voltage igenzura kugirango uhindure voltage yinjiza ya ecran yerekana, hanyuma amaherezo umenye ububengerane bwerekanwa rya ecran.
03Ibiranga
Guhindura imiterere yumucyo wumurongo wumucyo woherejwe na diode yerekana ecran, irangwa no kubamo: icyiciro cyinshingano zerekana igikoresho cyinjiza agaciro, compteur hamwe nuburinganire bugereranya, aho konte hamwe ninshingano yinteguza igenamigambi ryinjiza agaciro bikurikije agaciro. igereranwa nigiciro cyagenwe cyinshingano zinshyi mubunini bugereranya kugirango igenzure umusaruro wagereranijwe.
04LED adaptive dimming sisitemu yububiko
Umucyo wa LED uringaniza numuyoboro unyura muriwo werekeza imbere, kandi ubunini bwimbere bushobora guhinduka kugirango uhindure urumuri rwa LED.Kugeza ubu, urumuri rwa LED rusanzwe ruhindurwa muguhindura imikorere ikora cyangwa ubugari bwa pulse.Iyambere ifite intera nini yo guhindura, umurongo mwiza, ariko gukoresha ingufu nyinshi.Ntibikoreshwa rero.Uburyo bwa pulse ubugari bwo guhindura uburyo bukoresha inshuro nyinshi kugirango uhindure ibitanda, inshuro zo guhinduranya zirenze urugero abantu bashobora kubona, kugirango abantu batumva ko hariho stroboscopique.Menya LED ihindagurika.
