ABSTRACT:
An apparatus for controlling illumination of a fluorescent lamp is disclosed which includes two transformers for heating cathodes of the fluorescent lamp. Also included are two ballasts for ballasting the fluorescent lamp having an input adapted to receive a source of A-C power and an output coupled to the fluorescent lamp. The ballasts provide power to the fluorescent lamp in excess of a normal rated power of the fluorescent lamp. The apparatus further includes a flasher relay for repeatedly cycling power at a cycling rate between power on and power off to the fluorescent lamp coupled to the output of the ballasts and to the fluorescent lamp, thereby causing the fluorescent lamp to flash at a flashing rate with a flashing intensity of light output which is greater than the flashing intensity of output of the fluorescent lamp under normal continuous operation. A remote control sensor may be connected to the apparatus to switch the apparatus between the flashing cycle and normal continuous operation. The remote control sensor may also be used to the control the flashing rate of the flasher relay. An audio modulation apparatus may also be operatively connected to the flasher relay to control the flashing rate of the apparatus with an audio signal.
