Abstract
A discharge lamp is disclosed, including a sealed vessel with an inner surface, at least one illuminating gas filled inside the sealed vessel, and a fluorescent layer coated on the inner surface. The composition of the fluorescent layer is adjusted according to a colored light emitted by the illuminating gas during a discharge process within the sealed vessel, such that the colored light is converted into a visible light after passing through the fluorescent layer.
