m or less, and the inner surface of the tube is coated with colored phosphors of red, green, blue, etc., and the ultraviolet rays from the discharge are converted into light of a specific color by the phosphor, so the same amount of power is input. This makes it possible to reduce changes in brightness due to color, and in particular to increase the brightness of light with short wavelengths.

ゴン（２Ｔｏｒｒ）と水銀蒸気を用いている。[Embodiment] Fig. 1 shows an embodiment of the present invention, in which a tube 1 having a translucent property and containing a discharge gas consisting of mercury vapor and a rare gas is provided with a tube having a facing interval of 3 cm or less at the center thereof. A pair of discharge electrodes 2 are arranged, the outer diameter of the spherical part of the tube body 1 is set to 70 mm or less, and the inner surface of the tube body 1 is coated with color phosphor 3 of red, green, blue, etc. In the embodiment, the second
As shown in the figure, the outer diameter of the spherical part of the tubular body 1 was 40 mm, the electrode interval was 5 mm, and argon (2 Torr) and mercury vapor were used as the discharge gas.
