摘要：A fluorescent lamp including a glass bulb, a protection layer formed on an innersurface of the glass bulb, and a phosphor layer formed on a surface of the protectionlayer. The surface of the protection layer that is in contact with the phosphor layer hascracks. The bulk density of the metal oxide particles in the protection layer is 80% ormore. The surface of the protection layer has 20 to 200 cracks per millimeter in a tubeaxis direction. The average particle diameter of the metal oxide particles is in the rangefrom 0.01 μm to 1 μm. The thickness of the protection layer is in the range from 0.5 μmto 5 μm.
