KuriItara-kurekura chip, ukoresheje tekinoroji imwe, imbaraga nyinshi za LED imwe, niko kugabanya urumuri, ariko birashobora kugabanya umubare wamatara yakoreshejwe, bifasha kuzigama ibiciro; Gutoya imbaraga za LED imwe, niko gukora neza kumurika. Nyamara, umubare wa LED usabwa muri buri tara uriyongera, ingano yumubiri wamatara iriyongera, kandi ingorane zo gushushanya za lens optique ziriyongera, bizagira ingaruka mbi kumurongo wo gukwirakwiza urumuri. Ukurikije ibintu byuzuye, LED hamwe numurongo umwe wapimwe wakazi wa 350mA nimbaraga za 1W mubisanzwe bikoreshwa.
Muri icyo gihe, tekinoroji yo gupakira nayo ni ikintu cyingenzi kigira ingaruka kumucyo wa LED. Ubushyuhe bwo kurwanya ubushyuhe bwa LED yumucyo bugaragaza neza urwego rwikoranabuhanga. Nibyiza tekinoroji yo gukwirakwiza ubushyuhe, niko bigabanya ubukana bwumuriro, niko urumuri rugenda rwiyongera, niko urumuri rwinshi nubuzima bwitara.
Kubijyanye nibikorwa byubu bigezweho byikoranabuhanga, niba urumuri rutanga urumuri rwa LED rwifuza kugera kubisabwa n'ibihumbi cyangwa ibihumbi icumi bya lumens, chip imwe ya LED ntishobora kubigeraho. Kugirango uhuze icyifuzo cyo gucana urumuri, isoko yumucyo ya chip nyinshi LED ihujwe mumatara imwe kugirango ihuze urumuri rwinshi. Intego yo kumurika cyane irashobora kugerwaho mugutezimbere urumuri rwa LED, gukoresha ibikoresho byinshi byo gupakira hamwe numuyoboro mwinshi binyuze muri chip-nini nini.
Hariho uburyo bubiri bwingenzi bwo gukwirakwiza ubushyuhe kuri chip ya LED, aribyo gutwara ubushyuhe hamwe nubushuhe. Imiterere yo gukwirakwiza ubushyuhe bwaAmataraikubiyemo ubushyuhe bwibanze hamwe na radiator. Isahani yo gushiramo irashobora kumenya ultra-high heat flux transfert no gukemura ikibazo cyo gukwirakwiza ubushyuhe bwaamashanyarazi menshi LED. Isahani yo kumena ni vacuum cavit ifite micro-structure kurukuta rwimbere. Iyo ubushyuhe bwimuwe buva mumasoko yubushyuhe bugana ahantu hahindutse umwuka, uburyo bukora mukuzimu buzabyara ibintu bya gaz gaz ya gaz ya gaz mukarere ka vacuum. Muri iki gihe, imiyoboro ikurura ubushyuhe kandi ingano ikaguka vuba, kandi icyiciro cya gaze kizuzura vuba urwobo rwose. Iyo gazi-icyiciro giciriritse gihuye nubushuhe bugereranije, hazabaho koroha, kurekura ubushyuhe bwakusanyirijwe mugihe cyo guhumeka, kandi uburyo bwamazi bwikonje buzasubira mumasoko yubushyuhe buturuka kuri microstructure.
Uburyo bukoreshwa cyane-imbaraga za chip ya LED ni: kwagura chip, kunoza imikorere yumucyo, gupakira hamwe numucyo mwinshi, hamwe numuyoboro munini. Nubwo ingano ya luminescence iriyongera ugereranije, ubwinshi bwubushyuhe nabwo buziyongera. Gukoresha ubushyuhe bwo hejuru bwumuriro ceramic cyangwa ibyuma bipakira ibyuma birashobora gukemura ikibazo cyo gukwirakwiza ubushyuhe no gushimangira umwimerere wamashanyarazi, optique nubushyuhe. Kugirango tunoze ingufu z'amatara ya LED, amashanyarazi akora ya chip ya LED arashobora kwiyongera. Inzira itaziguye yo kongera ibikorwa byakazi ni ukongera ubunini bwa chip ya LED. Ariko, kubera kwiyongera kwimirimo ikora, gukwirakwiza ubushyuhe byabaye ikibazo gikomeye. Gutezimbere uburyo bwo gupakira ibyuma bya LED birashobora gukemura ikibazo cyo gukwirakwiza ubushyuhe.
