2.Kudikanwa kwekupisa kupisa
Iro data rakakodzera rinoratidza kuti kana tembiricha ikadarika imwe kukosha, kutadza kwechishandiso kunokwira zvakanyanya, uye yega yega 2 ° C kuwedzera kwekushisa kwechikamu kunoderedza kuvimbika ne10%. Kuti uve nechokwadi chehupenyu hwechigadzirwa, pn junction tembiricha inowanzodiwa kuti ive pasi pe110 ° C. Sezvo tembiricha yepn junction ichikwira, chiedza-emitting wavelength yemuchena LED mudziyo uchachinja mutsvuku. Pa 100 ° C. Kureba kunogona kuchinjwa kubva ku4 kusvika ku9 nm tsvuku, izvo zvinoita kuti kunyura kwephosphor kuderera, iyo yose inopenya intensity ichaderera, uye chiedza chichena chromaticity chichava chakaipisisa. Kutenderedza tembiricha yekamuri, iyo inopenya kusimba kwe LED inodzikira neinenge 1% parita yetembiricha. Kana ma LED akawanda akarongwa mukuwanda kuti aumbe chiedza chichena chekuvhenekera hurongwa, dambudziko rekupisa kupisa rinonyanya kuoma, saka kugadzirisa dambudziko rekupisa kupisa kwave kudiwa kwemagetsi e LED. Kana kupisa kunokonzerwa nezvino hakugone kupera munguva uye kupisa kwejunction kwepn junction kunochengetwa mukati mehutano hunobvumirwa, hazvizokwanisi kuwana chiedza chakadzikama chinobuda uye kuchengetedza hupenyu hwetambo hwemwenje.
Zvido zvekurongedza zve LED: Kuti ugadzirise dambudziko rekupisa kupisa kwepamusoro-simba LED packaging, vagadziri uye vagadziri vemidziyo yemumba neyekunze vakagonesa iyo yekupisa sisitimu yemudziyo maererano nechimiro uye zvinhu.
(1) Pakeji chimiro. Kuti ugadzirise dambudziko rekupisa kupisa kwepamusoro-simba re LED packaging, zvivako zvakasiyana-siyana zvakagadziriswa pasi rose, kunyanya kusanganisira silicon-based flip-chip (FCLED) chimiro, metal circuit board-based structure, uye micro-pombi chimiro; Mushure mekunge chimiro chepakeji chatemerwa, kupisa kwekupisa kweiyo system kunowedzera kuderedzwa nekusarudza zvinhu zvakasiyana-siyana zvekuvandudza thermal conductivity yehurongwa.
