Estimating the term…
A portable fluorescent tube assembly is disclosed having a relatively low voltage electric convenience outlet associated with the assembly. Although higher than normally supplied voltages are needed to initiate the lighting of a fluorescent tube, these voltages are unsuited for energizing still other electrical apparatus which is designed for normally supplied voltages. The circuitry of the present fluorescent tube assembly supplies both relatively high and low voltages at the portable unit itself, so that the tube can be fired to initiate lighting at the relatively high voltage, and yet other electrical apparatus can be energized directly from the portable assembly at a relatively low voltage.
In a fluorescent tube assembly having starter switch means and an electric convenience outlet associated with the assembly but apart from terminals of such fluorescent tube, electric circuitry therefor comprising conductors adapted to be connected to a source of electrical energy having a predetermined voltage, one of said conductors being connected in series to said convenience outlet and said starter switch means, another of said conductors being connected to said convenience outlet and in parallel through ballast means to said starter switch means, whereby said predetermined voltage is supplied to said convenience outlet associated with the tube assembly, and another and higher voltage is applied to said starter switch means and fluorescent tube for starting the same.
A fluorescent tube assembly including a fluorescent tube having end contact pins and starting filament means, an electrical convenience outlet physically located on such assembly but energized other than through said contact pins of the tube, said outlet being adapted to energize other electrical apparatus at one voltage, and a starter switch associated with the assembly for firing the fluorescent tube through said filament means adapted to operate at a second and higher voltage, and circuitry for the assembly including a pair of electrical conductors adapted to be connected to a source of electrical energy supplied at said one voltage, one of said conductors being connected in series with said convenience outlet, said starting filament means and said starter switch, the other of said electrical conductors being connected to said convenience outlet to supply an electric potential thereto at said one voltage directly from said source of electrical energy, and in parallel through ballast means to said starter switch to supply an electric potential thereto at another and higher voltage adapted to fire and operate said fluorescent tube.
A fluorescent tube assembly including a single tube having pin terminals and starting filament means at each end, an electric convenience outlet on the assembly having a pair of terminals energized other than through said pin terminals of the tube adapted to energize still other electrical apparatus at one voltage, and a starter switch having primary circuit terminals adapted to energize the tube after it is fired and secondary circuit terminals adapted to fire the tube through said starting filament means to initiate its lighting, and electric circuitry for the tube comprising:
A portable fluorescent tube assembly adapted to be connected to a source of electric energy having at the portable assembly itself circuitry providing both a relatively high voltage for firing the tube through starting filaments thereof and a relatively low voltage energized directly from said source of electric energy for electrically energizing other electric apparatus.
