Abstract
PURPOSE:To prevent an object to be illuminated from discoloring or deteriorating by coating the outer surface of a glass canopy with a primer containing titania. CONSTITUTION:Coating the outer surface of a glass canopy housing in its inside a light emitting tube with a primer containing titania, the primer is coated with a fluorine resin film. Here, the amount of titania is made to 0.5-15% weight of the primer. The thickness of the fluorine resin film, in the case the amount of titania is as described above, is made such that the light transmission rate becomes 95-99%.
