METHOD OF COATING PHOSPHORS ON FLUORESCENT LAMP GLASS

摘要

In process for forming a coating of phosphor particles on a fluorescent lamp glass, a polymer is deposited on the phosphor particles and the phosphor particles are entrained in a carrier gas with the polymer in a non-adhering state, and then the phosphor particles are coated on the fluorescent lamp glass with the polymer in an adhering state for retaining the phosphor particles on the fluorescent glass and, the coated fluorescent glass is heated to a temperature above the decomposition temperature of the polymer for removing the polymer and to form a coating of phosphor particles on a fluorescent lamp glass.
