Abstract
A fluorescent lamp that can be easily manufactured to provide high brightness and high efficiency, a method of manufacturing the same, and a backlight unit having the same are provided. First and second non-emissive glass tube are joined to an emissive glass tube coated with a phosphor, and first and second electrodes are formed on outer surfaces of the first and second non-emissive glass tubes. The first and second non-emissive tubes may have the same diameter as the emissive glass tube. The first and second non-emissive glass tubes are simply joined to the emissive glass tube, thereby reducing the manufacturing process and cost. The first and second non-emissive glass tubes are formed to be thinner than the emissive glass tube, thereby enhancing the brightness and efficiency of the fluorescent lamp.
