LED. na N ifite ubuzima bwigihe kigera kuri 20 kurenza amatara ya fluorescent cyangwa amatara yaka.Ibi biradufasha gutondeka byoroshye ibyiza byinshi byaItara.

Diyode itanga urumuri ni ikintu cyingenzi gikoreshwa muri elegitoroniki mu myaka myinshi, ariko vuba aha bamenyekanye cyane kubera LED zifite ingufu nyinshi, zitanga urumuri rukomeye bihagije kugirango rukoreshwe mu gusimbuza amatara ya florescent ya mercure, amatara yaka cyangwa ibyo bita ingufu za fluorescent amatara.

Kuri ubu, hari isoko ya LED hamwe na modul biboneka ku isoko, bifite imbaraga zihagije zo gukoreshwa nko gucana ibikorwa remezo nko kumurika umuhanda cyangwa parike, ndetse no kumurika inyubako zububiko bwibiro, stade nibiraro.Bagaragaza kandi ko ari ingirakamaro nkisoko yambere yumucyo mubihingwa bitanga umusaruro, mububiko ndetse nu mwanya wibiro.

Muri sisitemu ya LED isimbuza itara risanzwe, amatara akoreshwa cyane ni LED SMD na COB nayo yitwa Chip LEDs hamwe nibisohoka kuva 0.5W kugeza 5W kumuri murugo no kuva 10W - 50W kugirango bikoreshe inganda.Noneho, LED yamurika ibyiza byayo?Yego, ariko kandi ifite aho igarukira.Niki?

Ibyiza byo kumurika LED

Kuramba kuramba- ni imwe mu nyungu zikomeye zamatara ya LED.LED ikoreshwa muri ubu bwoko bwamatara ifite akazi keza cyane bityo irashobora gukora mugihe cyimyaka 11 ugereranije namatara azigama ingufu hamwe nubuzima bwa serivisi butarenze umwaka.Kurugero, LED ikora amasaha 8 kumunsi izamara imyaka 20 yubuzima bwa serivisi, kandi nyuma yiki gihe, tuzahatirwa gusimbuza isoko yumucyo iyindi nshya.Byongeye kandi, kuzimya kenshi no kuzimya nta ngaruka mbi bigira mubuzima bwa serivisi, mugihe bigira ingaruka nkizo mugihe cyamatara ashaje.

Gukora neza - LED ni isoko yingufu zikoreshwa cyane mukoresha ingufu nke cyane (amashanyarazi) kuruta gucana, fluorescent, meta halide cyangwa amatara ya mercure, muburyo bwo kumurika 80-90% kumurika gakondo.Ibi bivuze ko 80% byingufu zitangwa kubikoresho bihinduka urumuri, mugihe 20% byazimiye bigahinduka ubushyuhe.Imikorere yamatara yaka iri kurwego rwa 5-10% - gusa iyo mbaraga zitangwa zihinduka urumuri.

Kurwanya ingaruka n'ubushyuhe - bitandukanye no kumurika gakondo, urumuri rwa LED ni uko rutarimo filime cyangwa ibirahuri, byunvikana cyane no gukubitwa.Mubisanzwe, mukubaka amatara yo mu rwego rwo hejuru LED, hakoreshwa plastike yo mu rwego rwo hejuru hamwe na aluminiyumu, ibyo bigatuma LED ziramba kandi zihanganira ubushyuhe buke no kunyeganyega.

Kwimura ubushyuhe - LED, ugereranije n’itara gakondo, itanga ubushyuhe buke kubera imikorere yabo yo hejuru.Uyu musaruro w'ingufu ahanini utunganyirizwa kandi ugahinduka urumuri (90%), rutuma abantu bahura nisoko ryamatara ya LED nta guhura n’umuriro nyuma yigihe kinini cyakazi kandi wongeyeho kugarukira kumuriro, zishobora kugaragara mubyumba birimo
kumurika ubwoko bwa kera birakoreshwa, bishyushya kugeza kuri dogere magana.Kubera iyo mpamvu, kumurika LED nibyiza kubicuruzwa cyangwa ibikoresho byumva ubushyuhe bukabije.

Ibidukikije - ibyiza byo kumurika LED nabwo ni uko LED itarimo ibikoresho byuburozi nka mercure nibindi byuma byangiza ibidukikije, bitandukanye n’amatara azigama ingufu kandi ashobora gukoreshwa 100%, niki gifasha kugabanya dioxyde de carbone imyuka ihumanya ikirere.Harimo ibimera bivura ibara ryumucyo wacyo (fosifore), bitangiza ibidukikije.

Ibara - Muri tekinoroji ya LED, turashoboye kubona buri rumuri rumurika.Amabara yibanze ni yera, umutuku, icyatsi nubururu, ariko hamwe nikoranabuhanga ryiki gihe, iterambere riratera imbere kuburyo dushobora kubona ibara iryo ariryo ryose.Buri sisitemu ya LED RGB kugiti cye ifite ibice bitatu, buri kimwe gitanga ibara ritandukanye nibara rya RGB palette - umutuku, icyatsi, ubururu.

Igiciro - Itara rya LED nigiciro gihenze kuruta isoko yumucyo gakondo.Nyamara, ni ngombwa kuzirikana ko hano igihe cyo kubaho ari kirekire cyane (hejuru yimyaka 10) kuruta kumatara asanzwe kandi icyarimwe ikoresha ingufu nke ugereranije nubwoko bwa kera bwamatara.Mugihe cyo gukora urumuri rumwe rwa LED rwubuziranenge, twahatirwa kugura min.Amatara 5-10 yubwoko bwa kera, ntabwo byanze bikunze bivamo kuzigama ikotomoni yacu.

Ubushyuhe bukabije - Ubwiza bwamatara ya diode biterwa cyane nubushyuhe bwibidukikije.Ku bushyuhe bwo hejuru hari impinduka mubipimo byubu byanyuze muri semiconductor element, bishobora kuganisha ku gutwika module ya LED.Iki kibazo kireba gusa ahantu hamwe nubuso bugaragazwa nubwiyongere bwihuse bwubushyuhe cyangwa ubushyuhe bwinshi cyane (insyo zibyuma).
