Kuri ecran ya LED, abantu benshi batekereza ko ibikoresho nyamukuru bya ecran, LED na IC, bifite ubuzima bwamasaha 100.000.Ukurikije iminsi 365 / umwaka, amasaha 24 / kumunsi, ubuzima bwa serivisi burenze imyaka 11, kubakiriya benshi rero bitaye gusa kubikoresha bizwi cyane bya LED na IC.Mubyukuri, ibi byombi nibisabwa gusa, ntabwo ari ibintu bihagije, kuko gukoresha neza amatara yumutuku, icyatsi nubururu ni ngombwa cyane kuri ecran yerekana.Kugaragaza bizaba ngombwa.Guhindura gushyira mu gaciro IC nayo ifasha gutsinda ikibazo cyinsinga zidafite ishingiro za PCB
Ibintu by'ingenzi hano ni:
Kubera ko LED na IC ari ibikoresho bya semiconductor, birahitamo kubyerekeye imikoreshereze y’ibidukikije, byaba byiza hafi 25 ° C ku bushyuhe bw’icyumba, kandi uburyo bwabo bwo gukora ni bwiza.Ariko mubyukuri, ecran nini yo hanze izakoreshwa mubidukikije bitandukanye, bishobora kuba hejuru ya 60 ° C mugihe cyizuba no munsi ya -20 ° C mugihe cy'itumba.
Iyo uwabikoze akora ibicuruzwa, bakoresha 25 ° C nkibizamini, kandi bagashyira ibicuruzwa bitandukanye mubyiciro.Nyamara, imikorere nyayo ni 60 ° C cyangwa -20 ° C.Muri iki gihe, imikorere ikora nimikorere ya LED na IC ntibihuye, kandi birashobora kuba mubyiciro byambere.Bizahinduka urwego-rwinshi, urumuri ruzaba rudahuye, kandi ecran ya LED isanzwe ihinduka.
Ibi ni ukubera ko urumuri rwiyongera nigitonyanga cyamatara atukura, icyatsi nubururu bitandukanye mubihe byubushyuhe butandukanye.Kuri 25 ° C, uburinganire bwera nibisanzwe, ariko kuri 60 ° C, LED y'amabara atatu LED Umucyo wa ecran wagabanutse, kandi agaciro kayo ko kwiyegereza ntigahuye, bityo phenomenon ya ecran ya ecran yose igabanuka kandi amabara azabikora bibaho, kandi ubwiza bwa ecran yose buzagabanuka.Bite ho kuri IC?Ubushyuhe bwo gukora bwa IC ni -40 ℃ -85 ℃.
Ubushyuhe imbere mu gasanduku bwiyongera kubera ubushyuhe bwo hanze.Niba ubushyuhe buri imbere mu gasanduku burenze 85 ° C, IC izakora idahungabana kubera ubushyuhe bwinshi, cyangwa ikigezweho hagati yimiyoboro cyangwa itandukaniro riri hagati ya chipi izaba nini cyane kubera ubushyuhe butandukanye.Kuganisha kuri Huaping.
Muri icyo gihe, gutanga amashanyarazi nabyo ni ngombwa cyane.Kuberako amashanyarazi afite imbaraga zitandukanye zakazi, gusohora voltage agaciro nubushobozi bwo gutwara ibintu mubihe bitandukanye byubushyuhe, kuko ishinzwe infashanyo yibikoresho, ubushobozi bwayo bwo gufasha bugira ingaruka kumiterere ya ecran.
Igishushanyo cyagasanduku nacyo ni ingenzi cyane kuri ecran ya ecran.Ku ruhande rumwe, ifite umurimo wo kurinda umuzunguruko, kurundi ruhande, ifite umurimo wumutekano, kandi ifite n'umurimo wo kutagira umukungugu ndetse n’amazi adafite amazi.Ariko icy'ingenzi ni ukumenya niba igishushanyo mbonera cya sisitemu yubushyuhe bwo guhumeka no gukwirakwiza ubushyuhe ari cyiza.Hamwe no kwagura igihe cyo gutangira no kwiyongera kwubushyuhe bwo hanze, gutwarwa nubushyuhe bwibice nabyo biziyongera, bikavamo ubwiza bwibishusho.
Ibi bintu byose bifitanye isano kandi bizagira ingaruka kumiterere nubuzima bwerekanwa.Kubwibyo, mugihe umukiriya ahisemo ecran, agomba kandi kwitegereza no gusesengura byimazeyo kandi agacira urubanza rukwiye.
