Qhov laj thawj yog vim li cas qhov kub thiab txias cuam tshuam rau lub teeb ua haujlwm ntawm LED zaub
Oct 16, 2022| (1) Raws li qhov kub thiab txias nce, qhov concentration ntawm electrons thiab qhov nce, qhov sib txawv ntawm qhov band yuav txo, thiab cov electron txav tau qis.
(2) Thaum qhov kub thiab txias nce, qhov hluav taws xob recombination tshwm sim ntawm cov hluav taws xob thiab qhov hauv qhov muaj peev xwm zoo txo qis, ua rau tsis muaj hluav taws xob rov ua dua tshiab (cua sov), yog li txo qis hauv quantum efficiency ntawm LED zaub.
(3) Qhov nce hauv qhov kub thiab txias ua rau lub ncov xiav nthwv dej ntawm cov nti hloov mus rau qhov kev taw qhia yoj ntev, uas ua rau lub emission wavelength ntawm cov nti tsis sib haum rau qhov excitation wavelength ntawm cov phosphor, thiab kuj txo cov hluav taws xob sab nraud extraction efficiency. dawb LED zaub.
(4) Raws li qhov kub thiab txias, qhov quantum efficiency ntawm phosphor txo, lub luminescence txo, thiab sab nraud lub teeb extraction efficiency ntawm LED zaub txo.
(5) Kev ua haujlwm ntawm silica gel cuam tshuam zoo heev los ntawm qhov kub thiab txias. Raws li qhov kub thiab txias, qhov thermal stress nyob rau hauv silica gel nce, uas ua rau txo qis refractive Performance index ntawm silica gel, uas cuam tshuam rau lub teeb efficiency ntawm LED zaub.
