Control circuitry causes a fluorescent lamp to flash by cycling the primary of the lamp ballast reactor at a desired cycle rate. This results in the average lamp wattage output being generally about 40% to 60% Go its normal wattage rating. This results in a correspondence reduction in lumen output. In such flashing, the intensity or light output of each flash is approximately the same as its normal, continuous light output.

System for controlling fluorescent lamp operation and illumination

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.

Apparatus for controlling illumination of a fluorescent lamp

A skin tanning lamp construction of a fluorescent type is described utilizing a combination of two different phosphor materials in order to provide a more effective sun tanning source. The particular phosphor combination can be utilized as a blended mixture having a preselected level of one phosphor component to limit the amount of erythemal radiation produced by said mixture.
