Isesengura rya LED Kumurika Porogaramu mukarere gakonje
Nyuma yimyaka 10 yiterambere ryihuse, itara rya LED ryinjiye mubyiciro byiterambere, kandi isoko ryagiye ryiyongera buhoro buhoro kuva mukarere ka majyepfo yepfo kugera mukarere ko hagati no muburengerazuba. Ariko, mubikorwa nyabyo, twasanze ibicuruzwa byo kumurika hanze bikoreshwa mumajyepfo byageragejwe neza mukarere ka majyaruguru, cyane cyane amajyaruguru yuburasirazuba. Iyi ngingo isesengura bimwe mubintu byingenzi bigira ingaruka kumatara ya LED mubidukikije bikonje, ikamenya ibisubizo bihuye, hanyuma ikazana ibyiza byumucyo LED.
Ubwa mbere, ibyiza byo kumurika LED ahantu hakonje
Ugereranije n’itara ryambere ryaka, itara rya fluorescent hamwe n’itara ryinshi risohora gaze, imikorere yimikorere ya LED ni nziza cyane kubushyuhe buke, ndetse dushobora no kuvuga ko imikorere ya optique ari nziza cyane kuruta ubushyuhe busanzwe. Ibi bifitanye isano ya hafi nubushyuhe bwibikoresho bya LED. Mugihe ubushyuhe bwihuriro bugabanuka, urumuri rwamatara ruziyongera ugereranije. Ukurikije itegeko ryo gukwirakwiza ubushyuhe bwitara, ubushyuhe bwihuza bufitanye isano rya hafi nubushyuhe bwibidukikije. Hasi ubushyuhe bwibidukikije, niko ubushyuhe bwo guhuza bugomba kuba. Byongeye kandi, kugabanya ubushyuhe bwihuriro birashobora kandi kugabanya uburyo bwo kwangirika kwurumuri rwumucyo wa LED no gutinza igihe cyumurimo wamatara, nacyo kiranga ibintu byinshi bya elegitoroniki.
Ingorane hamwe nuburyo bwo guhangana n’umucyo wa LED mu bidukikije bikonje
Nubwo LED ubwayo ifite ibyiza byinshi mubihe bikonje, ntishobora kwirengagizwa ko usibye amasoko yumucyo. Amatara ya LED nayo afitanye isano rya bugufi nimbaraga zo gutwara, ibikoresho byumubiri wamatara, nikirere cyijimye, ultraviolet nizindi kirere cyuzuye mubihe bikonje. Ibintu byazanye ibibazo bishya nibibazo mugukoresha iyi soko nshya yumucyo. Gusa mugusobanura izo mbogamizi no gushaka ibisubizo bihuye, turashobora gutanga umukino wuzuye kubyiza bitanga urumuri rwa LED kandi bikamurika mubukonje.
1. Ikibazo cyo gutangira ubushyuhe buke bwo gutwara amashanyarazi
Umuntu wese ukora iterambere ryamashanyarazi azi ko ubushyuhe buke gutangira amashanyarazi ari ikibazo. Impamvu nyamukuru nuko ibyinshi mubisubizo byimbaraga zikuze zidashobora gutandukana mugukoresha kwinshi kwa capacitori ya electrolytike. Nyamara, mubushyuhe buke buri munsi ya -25 ° C, ibikorwa bya electrolytike ya capacitori ya electrolytike biragabanuka cyane, kandi ubushobozi bwa capacitance bwarushijeho kwiyongera, ibyo bigatuma umuziki udakora neza. Kugira ngo iki kibazo gikemuke, kuri ubu hari ibisubizo bibiri: kimwe ni ugukoresha ubushobozi bwo mu rwego rwo hejuru hamwe nubushyuhe bwagutse bwo gukora, birumvikana ko bizamura ibiciro. Iyakabiri nigishushanyo cyumuzingi ukoresheje capacitori ya electrolytique, harimo na ceramic laminated capacator, ndetse nubundi buryo bwo gutwara nka drayine.
Byongeye kandi, munsi yubushyuhe buke, kwihanganira imbaraga za voltage yibikoresho bisanzwe bya elegitoronike nabyo bizagabanuka, ibyo bizagira ingaruka mbi kubwizerwa rusange bwumuzunguruko, bisaba kwitabwaho byumwihariko.
2. Kwizerwa kwibikoresho bya pulasitike munsi yubushyuhe buke kandi buke
Dukurikije ubushakashatsi bwakozwe n’abashakashatsi bo mu bigo bimwe na bimwe by’ubushakashatsi mu gihugu ndetse no hanze yacyo, ibikoresho byinshi bya pulasitiki na rubber bifite ubukana buke kandi byongera ubukana ku bushyuhe buke buri munsi ya -15 ° C. Ku bicuruzwa byo hanze bya LED, ibikoresho bibonerana, lensike optique, kashe na bimwe ibice byubatswe birashobora gukoresha ibikoresho bya pulasitiki, bityo imiterere yubukonje buke bwibikoresho bikenera gusuzumwa neza, cyane cyane ibice bitwara imizigo, kugirango wirinde amatara Munsi yubushyuhe buke, izaturika nyuma yo gukubitwa numuyaga mwinshi kandi impanuka.
Mubyongeyeho, LED luminaire ikunze gukoresha ibice bya plastiki nicyuma. Kuberako coefficient zo kwagura ibikoresho bya pulasitiki nibikoresho byicyuma biratandukanye cyane mugihe kinini cyubushyuhe butandukanye, kurugero, coefficient zo kwaguka za aluminium yicyuma nibikoresho bya pulasitike bikunze gukoreshwa mumatara biratandukanye inshuro 5, bishobora gutera ibikoresho bya plastike gucika cyangwa icyuho hagati yombi. Niba byiyongereye, imiterere ya kashe idafite amazi amaherezo izateshwa agaciro, bizatera ibibazo byibicuruzwa.
Mu karere ka alpine, kuva mu Kwakira kugeza muri Mata umwaka ukurikira, hashobora kuba mu gihe cy'urubura na barafu. Ubushyuhe bw'itara rya LED burashobora kuba munsi ya -20 ℃ hafi nimugoroba mbere yuko itara ryaka nimugoroba, hanyuma amashanyarazi amaze gucanwa nijoro, ubushyuhe bwumubiri wamatara burashobora kuzamuka kugera kuri 30 ℃ ～ 40 ℃ kubera gushyushya itara. Inararibonye hejuru yubushyuhe buke kandi buke. Muri ibi bidukikije, niba igishushanyo mbonera cya luminaire hamwe nikibazo cyo guhuza ibikoresho bitandukanye kidakemuwe neza, biroroshye gutera ibibazo byo guturika ibintu no kunanirwa n’amazi twavuze haruguru.
