<P>PROBLEM TO BE SOLVED: To use lighting equipment for a two-tube series sequentially starting fluorescent lamp to cause a solid-state light-emitting element lamp to surely emit light, and to cause both lamps to have the same brightness. <P>SOLUTION: A solid-state light-emitting element lamp that emits light by receiving power supply from lighting equipment for a two-tube series sequentially starting fluorescent lamp includes current control means for controlling a current value in such a way that, when the two solid-state light-emitting element lamps are connected in series for emitting light, voltage to be applied for each of the solid-state light-emitting element lamps is made to be half or lower than the maximum voltage that can be output from the lighting equipment for the two-tube series sequentially starting fluorescent lamp. <P>COPYRIGHT: (C)2013,JPO&INPIT |
