Abstract

A strip of a flexible plastic has a transparent cover surface which permits passage of light and an opposed bottom surface and sides which are opaque to passage of light. A series of spaced apart light emitting diodes are positioned on the top surface in electrical contact with a pair of spaced apart, generally parallel electrical wires running along the length of the top surface and individual electric bulbs are positioned on top of each light emitting diode. When electric current flows through the electrical wires, light is transmitted from each light emitting diode through each bulb and out in a unidirectional manner.

Claims

1. A generally rectangular tubular electric lighting system capable of transmitting electric light in only one predetermined direction, said tubular electric lighting system defined by a strip of elongated flexible plastic formed with a top light transmitting surface and opaque bottom and side surfaces, wherein light is transmitted through said light transmitting surface in only one direction, said open top having a transparent cover, a pair of generally parallel electric wires extending through said top surface electrically connected to a source of electrical power, several spaced apart light emitting diodes each placed on said top surface and connected to said pair of electric wires, a light emitting bulb positioned in contact with each of said light emitting diodes and adapted to transmit light from each of said light emitting diodes to the outside of said bulb in one predetermined direction through the light transmitting side surface.

2. An electric lighting system as in claim 1 wherein each of said bulbs is preformed with an open bottom having a generally U-shaped base having a central opening aligned with said open bottom of said bulb thereby allowing transmittal of light through said base to said bulb and out through said predetermined direction.

3. An electric system as in claim 1 wherein said light emitting diodes are spaced equidistantly.

4. An electric system as in claim 2 wherein said light emitting diodes are spaced equidistantly.

5. An electric system as in claim 1 wherein said plastic strip is made of polyvinylchloride.

6. An electric system as in claim 2 wherein said plastic strip is made of polyvinylchloride.

7. An electric system as in claim 3 wherein said plastic strip is made of polyvinylchloride.

8. An electric system as in claim 4 wherein said plastic strip is made of polyvinylchloride.
