Abstract:
Process for coating elongated lamp envelope for reflector-type fluorescent lamp in which only one lehring step is used to remove binder from the applied plural coatings, thereby reducing lamp costs and simplifying the coating process. The reflector portion of the coating is formed of mixed titania and phosphor, which permits the reflective material to be removed from the end portions of the coated envelope after the applied reflective material coating and overlying phosphor have been lehred. There is also provided the resulting lamp.
