Abstract
A method of filling and sealing a fluorescent layer in a slot space defined by two optical lenses and a partition ring is disclosed, in which a slot space is defined by two optical glasses and a partition frame having a partition ring on the inner wall surface. The partition frame is installed with two slots diametrically opposite to each other, and the slot space is evacuated to allow filling of a fluorescent material, and then the two slots are sealed so that the moisture is prevented from permeating into the fluorescent layer, and thus the optical performance can be maintained over a long period.
