Abstract

PURPOSE:To restrict the decrease in the emission output of a fluorescent lamp by applying a phosphor having a specific gravity of over 4.1 to the inner wall of a bulb, before making a micro powder to adhere to the phosphor layer near the electrodes which are provided at the ends of the bulb. CONSTITUTION:Electrodes 2 are fused to the inner ends of a glass bulb 1 of a fluorescent lamp 1. 3-7mg/cm<2> thick phosphor is applied to the inner wall of the glass bulb 1 to make the inner wall to be coated with a phosphor layer 3. After that, a micro powder 4 is made to adhere to the A-side phosphor layer 3 formed on the glass bulb 1, so that the electrodes 2 are shielded. Owing to the above constitution, the electrodes 2 are prevented from being seen through without causing any decrease in the emission output, and any increase in the material cost.
