ABSTRACT:
An illumination control apparatus using a pulsating wave is disclosed, in which a pulsating power is supplied to an electric power supplied to a fluorescent light stabilizer which needs an AC voltage. The level of the same is varied and supplied to an illumination control, such as fluorescent light and common light, is possible based on an input power control of a stabilizer without changing an installation of a conventional fluorescent light and common light device and of the power construction. In addition, the electric power can be concurrently supplied to a plurality of stabilizers based on a capacity of apparatus without changing the construction of a conventional system.
