Yog vim li cas vim li cas LED teeb hlaws dai cuam tshuam los ntawm qhov kub thiab txias thiab ua rau pob tsis ua haujlwm
Lub neej expectancy ntawm LED teeb hlaws yog kwv yees kom tshaj 50, 000 teev. Tab sis lub neej no hais txog lub neej theoretical, lub neej ntawm lub teeb hlaws ntawm 25 degree. Nyob rau hauv cov txheej txheem siv tiag tiag, hnyav ib puag ncig xws li qhov kub thiab txias yuav tsum tau ntsib, uas yuav ua kom pom qhov tsis xws ntawm LED teeb hlaws, ua kom cov khoom siv aging, thiab ua rau LED teeb hlaws ua tsis tau sai.
Cov nyhuv ntawm qhov kub thiab txias ntawm kev ntseeg tau ntawm LED teeb hlaws ntim ntim
Los ntawm kev sim kev tshawb fawb ntawm cov av noo ib puag ncig, nws pom tau hais tias kev nkag mus ntawm cov av noo tsis tsuas yog txo cov luminous efficiency ntawm LEDs, tab sis kuj yuav ua rau muaj kev puas tsuaj loj ntawm LED teeb hlaws dai. Los ntawm 85 degree / 85 feem pua RH qhov kub thiab txias thiab cov av noo nrawm nrawm kev ntseeg siab, nws pom tias cov dej noo ua lub luag haujlwm tseem ceeb hauv kev tsim cov delamination tsis xws luag. Qhov tshwm sim delamination txo cov teeb pom kev zoo ntawm LEDs, thiab qhov roughness ntawm cov chips sib txawv. txawv hom kev ua tsis tiav.
Yog vim li cas vim li cas qhov kub thiab txias ua rau LED teeb hlaws thiab lub kaw lus tsis ua haujlwm yog:
1. Vim yog qhov tsis sib xws ntawm thermal conductivity ntawm cov khoom ntim, qhov tsis sib xws ntawm qhov kub thiab txias gradient, cov kab nrib pleb yuav tshwm sim hauv cov khoom lossis delamination yuav tshwm sim ntawm qhov sib cuam tshuam ntawm cov ntaub ntawv. Cov kab nrib pleb thiab delamination yuav ua rau lub teeb pom kev zoo poob. Lub delamination ntawm nti thiab phosphor txheej yuav txo tau lub teeb extraction efficiency. Lub delamination ntawm phosphor txheej thiab potting silica gel yuav txo tau lub teeb extraction efficiency ntau tshaj 20 feem pua. . Delamination ntawm silicone thiab substrate tuaj yeem ua rau cov hlau kub tawg, ua rau muaj kev puas tsuaj loj.
2. Qhov kub thiab txias yuav ua rau kom qhov degradation ntawm cov khoom ntim thiab txo kev ua haujlwm;
3. Qhov ntsuas kub sib txuas yuav muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm LED teeb hlaws. Qhov kub ntawm qhov sib txuas ntau dhau yuav ua rau cov phosphor txheej kub hnyiab dub thiab carbonize, uas yuav txo tau qhov ua tau zoo ntawm LED teeb hlaws lossis ua rau muaj kev puas tsuaj loj.
Tsis tas li ntawd, vim qhov tsis sib haum xeeb ntawm qhov ntsuas qhov ntsuas qhov ntsuas kub thiab qhov thermal expansion coefficient ntawm silica gel thiab phosphor hais, qhov kub thiab txias yuav txo qhov kev hloov pauv ntawm cov phosphor hmoov, thiab qhov ntau dua qhov feem ntawm phosphor hmoov doped, qhov hnyav dua. qhov txo qis hauv luminous efficiency.
