Abstract

PURPOSE: To make the radiation of light to the rear proper by coating a fluorescent substance layer thickly on the frontal side of the fluorescent tube and thinly on the rear side.
CONSTITUTION: The fluorescent layer 6 is coated thickly (d1) on the frontal side of the fluorescent tube 1 and thinly (d2) on the rear side by a coating manner in which a paint is injected by biasing the nozzle 9 from the center of the fluoresent tube 1 or by using a nozzle whose small holes 10' are biassed to one direction, but not at equal intervals. Also, the mark 7 to desginate the front or rear direction is indicated in order to eliminate errors when being used. Thus, the radiation of light can be made proper as shown in Fig. c.
