Method for manufacturing discharge lamp, involves applying fluorescent material layer on surface of upper part and lower part by providing plate-type upper part and plate-type lower part

摘要

The method involves applying fluorescent material layer on a surface of the upper part and the lower part by providing a plate-type upper part (2) and a plate-type lower part (3), where an area of the upper part and lower part are made of a light-permeate material, and also removing water retention and accretions in or on the fluorescent layer by producing a gas stream, which streams through between the upper and lower parts producing a gas-tight connection to the circulating edge of the upper part and the lower part.
