Mu myaka yashize, hamwe niterambere ryihuse rya tekinoroji ya LED, ikoreshwa ryubucuruzi rya LED rimaze gukura.Ibicuruzwa bya LED bizwi nka "icyatsi kibisi" kubera ubunini bwacyo, gukoresha ingufu nke, ubuzima bumara igihe kirekire, umucyo mwinshi, kurengera ibidukikije, gukomera no kuramba, ndetse n'amatara akomeye ya LED azigama ingufu.Ukoresheje ultra-yaka kandi ifite ingufu nyinshi LED itanga urumuri, hamwe n’amashanyarazi menshi, irashobora kuzigama amashanyarazi arenga 80% kuruta amatara gakondo, kandi umucyo wikubye inshuro 10 iy'amatara yaka munsi yingufu zimwe.Ubuzima burebure bumara amasaha arenga 50.000, bukubye inshuro zirenga 50 iy'amatara gakondo ya tungsten.LED ikoresha ubuhanga bwizewe bwo gupakira tekinoroji-eutectic welding, itanga ubuzima burambye bwa LED.Igipimo cyerekana neza kirashobora kuba hejuru ya 80lm / W cyangwa irenga, ubushyuhe butandukanye bwibara ryamatara ya LED burahari, indangagaciro ndende yo kwerekana amabara, hamwe no gutanga amabara meza.LED yumucyo urumuri LED ikoranabuhanga rigenda ritera imbere uko bwije n'uko bukeye, imikorere yacyo ya lisansi itera intambwe ishimishije, kandi igiciro gihora kigabanuka.Nibicuruzwa bimurika, byinjiye mu ngo ibihumbi n’imihanda.
Nyamara, LED yumucyo utanga isoko ntanumwe wabuze.Kimwe nibicuruzwa byose byamashanyarazi, amatara ya LED azatanga ubushyuhe mugihe cyo kuyakoresha, biganisha ku kwiyongera kwubushyuhe bwibidukikije hamwe nubushyuhe bwabo.LED ni urumuri rukomeye rwumucyo ufite agace gato gasohora urumuri hamwe nubucucike bunini bwa chip mugihe gikora;mugihe imbaraga za LED imwe chip ari ntoya, kandi ibisohoka luminous flux nayo ni mike.Kubwibyo, mugihe gikoreshwa mubikoresho byo kumurika, amatara menshi arasaba Guhuza amasoko menshi yumucyo wa LED bituma LED yoroha.Kandi kubera ko igipimo cyamafoto yumuriro wa LED yumucyo utari hejuru, gusa 15% kugeza 35% byingufu zamashanyarazi bihinduka mumucyo, naho ibindi bigahinduka ingufu zubushyuhe.Kubwibyo, mugihe umubare munini wurumuri rwa LED rukorera hamwe, ingufu nyinshi zubushyuhe zizabyara.Niba ubu bushyuhe budashobora gukwirakwizwa vuba bishoboka, bizatera ubushyuhe bwo guhuza isoko yumucyo wa LED kuzamuka, kugabanya fotone yatanzwe na chip, kugabanya ubwiza bwibara ryibara, kwihuta gusaza kwa chip, no kugabanya ubuzima cy'igikoresho.Kubwibyo, isesengura ryumuriro hamwe nuburyo bwiza bwo gukwirakwiza ubushyuhe bwamatara ya LED biba ingenzi cyane.
Ukurikije imyaka yuburambe bwiterambere ryibicuruzwa bya LED mu nganda, hashyizweho uburyo bwuzuye bwo gushushanya.Nkumucyo wibicuruzwa byubaka, bihwanye no guhagarara ku bitugu by'ibihangange.Ariko, ntabwo aribyo byoroshye kugera hejuru kubitugu byibihangange.Hano haribibazo byinshi bigomba kuneshwa mugushushanya burimunsi.Kurugero, duhereye kubiciro, mugushushanya, birakenewe kuzuza ibisabwa kugirango ubushyuhe bugabanuke kubicuruzwa, ariko nanone kugabanya igiciro;kurubu, uburyo bukoreshwa cyane kumasoko nugukoresha aluminiyumu ya aluminiyumu kugirango ubushyuhe bugabanuke.Muri ubu buryo, nigute abashushanya Kugirango bamenye intera iri hagati ya fin na fin hamwe nuburebure bwa fin, kimwe ningaruka yimiterere yibicuruzwa kumyuka yikirere hamwe nicyerekezo cyubuso butanga urumuri, bizabikora biganisha ku gukwirakwiza ubushyuhe budahuye.Ibi nibibazo byugarije abashushanya.
Muburyo bwo gushushanya amatara ya LED, hariho inzira nyinshi zo kugabanya ubushyuhe bwa LED no kwemeza ubuzima bwa LED: ① Kongera ingufu zubushyuhe (hari uburyo butatu bwo guhererekanya ubushyuhe: gutwara ubushyuhe, guhana ubushyuhe bwa convection no guhana ubushyuhe bwimirasire) ,. ubushyuhe.
Noneho kugirango dushimangire gutwara ubushyuhe, dushobora gukoresha uburyo bukurikira: ①, uburyo bwiza bwo gukwirakwiza ubushyuhe bwa kabiri;, Kugabanya ubukana bwumuriro hagati yimikorere ya LED hamwe nuburyo bwo gukwirakwiza ubushyuhe bwa kabiri;, Kuzamura umubano hagati ya LED nuburyo bwa kabiri bwo gukwirakwiza ubushyuhe Ubushuhe bwubushuhe bwubuso;, Igishushanyo mbonera ukoresheje ihame ryo guhumeka ikirere.
Kubwibyo, gukwirakwiza ubushyuhe ni icyuho kidasubirwaho kubashushanya ibicuruzwa muruganda rumurika muriki cyiciro.Aha, ndizera ko hamwe niterambere ryiterambere rya tekinoloji, ingaruka zo gukwirakwiza ubushyuhe kuri LED zizagenda ziba nto.Turimo kugerageza kandi gushaka uburyo bwo kugabanya ubushyuhe bwa LEDs, kwemeza ubuzima bwa LED, no gukora ibicuruzwa bihendutse binyuze muburyo bwo gusaba..
