Nekukurumidza kukura kwemwenje we LED nhasi, kupisa kupisa ndiro dambudziko guru remwenje we LED.Tingagadzirisa sei dambudziko re LED kupisa dissipation?Nhasi tichataura nezve dambudziko re LED kupisa kupisa mhangura substrate ye LED kupisa kupisa.
Iyo indasitiri ye LED ndeimwe yemaindasitiri akakwezva kutarisisa kwakawanda mumakore achangopfuura.Kusvika parizvino, zvigadzirwa zve LED zvine zvakanakira kuchengetedza simba, kuchengetedza simba, kushanda zvakanaka, kukurumidza kupindura nguva, kutenderera kwehupenyu hurefu, mercury-isina, uye kuchengetedza kwezvakatipoteredza.Zvisinei, kazhinji inenge 15% yesimba rekuisa remagetsi emagetsi e LED zvigadzirwa zvinogona kuchinjwa kuva chiedza, uye 85% yakasara yesimba remagetsi rinoshandurwa kuita simba rekupisa.
Kazhinji, kana simba rekupisa rinogadzirwa nemwenje we LED risingakwanisi kutumirwa kunze kwenyika, tembiricha yejunction ye LED ichave yakanyanya kukwirira, izvo zvinokanganisa kutenderera kwehupenyu hwechigadzirwa, kupenya kwakanaka, uye kugadzikana.Hukama huri pakati pe LED junction tembiricha, inopenya kunyatsoshanda, uye hukama hwehupenyu.
Mu LED kupisa disipation dhizaini, chinhu chinonyanya kukosha ndechekudzikisa zvinobudirira kupisa kwekupisa kubva pachiedza-emitting layer ye chip kune zvakatipoteredza.Naizvozvo, zvinonyanya kukosha kusarudza yakakodzera kupisa kupisa substrate uye interface zvinhu.
Iyo inopisa yekupisa yemhangura substrate inotakura kupisa conduction kwe LED uye zvishandiso.Kupisa kwekupisa kunonyanya kuenderana nenzvimbo, uye substrate yemhangura ine high thermal conductivity inogona kusarudzwa kuti iwedzere kupisa conduction.
