CONSTITUTION:A constant relationship is formed among (l), (d), and a beam of light, where (d) is the outer diameter of U-shaped inner tubes 3, 3' and (l) is the separation distance between adjoining U-shaped inner tubes 3, 3' as shown in the figure. The relationship between the space ratio (l)/(d) and the output light ratio is shown in the figure, in which A is a measured value and B is a predicted value by a computer. The output light ratio is a relative value obtained by comparing the beam of light of said lamp with that of a straight tube lamp, rated as 100%, of the same specification as said lamp. By designing so as to satisfy an equation, the space ratio (l)/(d)>=1/2, the light shading due to the mutual effect between the inner tubes is made little, and the light output of about 90% or more can be obtained as compared with that of a straight tube fluorescent lamp of the same specification.
