<p>The inside of an outer peripheral wall (34a) of an elongate linear light source (3) is circumferentially equally partitioned by partition walls (34b). A pair of inner electrodes (33b) is received in each of the partitioned spaces and fluorescent bodies (31c, 32c, 33c) are applied on the inner surfaces of the individual outer peripheral walls (34a), and thereby fluorescent lamps (31, 32, 33) emitting light of different colors are formed. The linear light source (3) is formed by the fluorescent lamps (31, 32, 33) twisted, entwined, and wound around each other, and is capable of eliminating color irregularities of each color emitted from the lamps.</p> |
