  • Method and apparatus for coating fluorescent lamps
    Patent number: 5560958
    Abstract: A method and apparatus for sequentially coating fluorescent lamps with a protective coating. The lamps are advanced continuously through coating apparatus which prepares the surfaces of the lamps for coating, then dips the lamps in a bath of liquid coating material, and subsequently cures the liquid coating material. The lamps may be labeled prior to coating, such that the coating provides tamper resistance for the labeling, in addition to containment of shattered glass and lamp contents in the event of breakage of the lamp.
