SYSTEM AND METHOD OF COATING SUBSTRATES AND ASSEMBLING DEVICES HAVING COATED ELEMENTS

摘要

A system and method of coating curved substrates (22) and assembling devices having coated elements. The system and method are of particular utility in the manufacture of lamps (22) having a coating (12) formed on the hermetically sealed light emitting chamber (14) of the lamp (22). The system and method includes, inter alia, an improved uniform coating process and apparatus, improved throughput in the coating process, a reduction in bad coating losses, improved baking processes, and an improved method and apparatus for aligning the filament (28) of a halogen lamp (22) achieved by performing the step of coating of the light emitting chamber (14) prior to the step of sealing the chamber (14).
