Dab tsi yog lub ntsiab ntawm txoj kev loj hlob ntawm chip technology rau semiconductor teeb pom kev zoo?
Nrog rau kev txhim kho ntawm semiconductor LED thev naus laus zis, nws cov ntawv thov hauv thaj chaw teeb pom kev zoo kuj nce ntxiv, tshwj xeeb tshaj yog qhov tshwm sim ntawm cov LEDs dawb, uas tau dhau los ua qhov tshwj xeeb ntawm semiconductor teeb pom kev zoo. Txawm li cas los xij, cov chips tseem ceeb thiab cov txheej txheem ntim khoom tseem yuav tsum tau txhim kho, thiab cov chips yuav tsum tau tsim los ntawm lub zog siab, kev ua haujlwm siab lub teeb thiab txo qis thermal. Kev nce lub zog txhais tau hais tias tam sim no siv los ntawm cov nti yog nce. Qhov kev daws teeb meem ncaj qha tshaj plaws yog txhawm rau nce qhov loj ntawm cov nti. Tam sim no cov khoom siv hluav taws xob ntau yog li 1mm × 1mm, thiab tam sim no yog 350mA. Vim qhov nce ntawm qhov siv tam sim no, qhov teeb meem kub dissipation tau dhau los ua qhov teeb meem tseem ceeb, thiab tam sim no txoj kev flip nti yog qhov pib 350mA. Vim qhov nce ntawm qhov siv tam sim no, qhov teeb meem ntawm cov cua sov dissipation tau dhau los ua qhov teeb meem tseem ceeb, thiab tam sim no qhov teeb meem no tau daws los ntawm txoj kev flip nti. Nrog rau kev txhim kho ntawm LED thev naus laus zis, nws daim ntawv thov hauv thaj chaw teeb pom kev zoo yuav ntsib txoj hauv kev tsis tau pom dua thiab kev sib tw.
