First Claim
Patent Images
1. A method of manufacturing a decorative light tube comprising the steps of:
- (a) providing a plurality of lamps electrically interconnected, said interconnected lamps being sized to fit within a hollow, transparent tube; and
(b) coating said interconnected lamps with a quantity of dielectric substance, said quantity of dielectric substance being sufficient to form a protective cushioning layer between the interconnected lamps and the walls of the tube and to occupy up to about 50% of the interior of said tube when said interconnected lamps are in said tube.

Abstract
A decorative light and method of manufacture thereof, said light having an outer transparent tube, a pair of electrical supply wires in the tube, and a plurality of miniature lamps within the tube, the lamps being connected in series between the supply wires, and a protective dielectric material within the tube which coats the supply wires and the lamps forming a protective dielectric cushioning layer between said wires and lamps and the walls of the tube to prevent electrical failure of the decorative light tube circuit as a result of moisture, shock and vibration.

4. A method of manufacturing a decorative light tube having a plurality of lamps electrically interconnected by a conductor within a hollow, transparent tube to prevent electrical failure of the lamps caused by vibration of the tube, said method comprising the steps of:
-
(a) introducing a quantity of dielectric substance into the tube through an opening in the tube, said quantity being substantially less than the quantity of said substance that would be required to substantially fill the interior of the tube when the electrically interconnected lamps are in the tube; and (b) causing said dielectric substance to come in contact with and form a coating on the conductor, the lamps, and the interior of the tube. - View Dependent Claims (5, 6, 7, 8, 9)

10. A decorative light tube comprising:
-
a hollow, transparent tube; an electrical conductor in said tube; a plurality of lamps in said tube, said lamps being electrically connected to said conductor whereby said lamps are illuminated when an electric current is provided to said conductor; and means for bonding said lamps to the interior walls of said tube whereby the resonant frequency of said lamps is substantially reduced so that the filaments of said lamps do not become embrittled and broken as a result of higher frequency vibrations.

11. A decorative light tube comprising:
-
a hollow, transparent tube; an electrical conductor in said tube; a plurality of lamps in said tube, said lamps being electrically connected to said conductor whereby said lamps are illuminated when an electric current is provided to said conductor; and a protective coating on said conductor, said lamps, and the interior of said tube formed by; (a) introducing a quantity of dielectric substance into the tube through an opening in the tube, said quantity being substantially less than the quantity of said substance that would be required to substantially fill the interior of the tube when the electrically interconnected lamps are in the tube; and (b) causing said dielectric substance to come in contact with and form a coating on the conductor, the lamps, and the interior of the tube. - View Dependent Claims (12)

13. A decorative light tube comprising:
-
a transparent tube; an electrical conductor with an insulative coating in said tube; a plurality of lamps in said tube, said lamps being electrically interconnected to said conductor whereby said lamps are illuminated when an electric current is provided to said conductor; and a protective dielectric coating in said tube, said coating occupying substantially less than the entire internal space in said tube not occupied by said lamps and said conductor. - View Dependent Claims (14, 15, 16, 17)
