Abstract

PURPOSE: To reduce lamp cost and also to lessen the lowering of lamp luminous flux by making the ratio of fine particles in fluorescent substance to be coated on the glass tube side lower than the ratio of fine particles in fluorescent substance to be coated on the discharge side.
CONSTITUTION: The two fluorescent layers 2 and 3 are coated on the inside wall of the glass tube 1 by the procedure in which the fluorescent substance 2 having lesser amounts of fine particles is coated on the glass tube 1 side, and then on the fluorescent layer 2, or the discharge side, the fluorescent substance 3 having larger amounts of fine particles is coated. Thus, the lowering of luminous flux due to the remaining of undecomposed tackifier can be prevented.
