Abstract

An illuminated tape includes an elongated, thin tape element composed of flexible, and at least partially translucent, plastic. A pair of longitudinally extending thin wires are embedded in the plastic, and a plurality of LED chips, also embedded in the plastic, are electrically connected in parallel between the wires. The electrical elements are therefore completely embedded in plastic producing a flexible illuminated tape which can operate off a low power source and which is waterproof and safe.

Claims

1. A weatherproof, illuminated tape comprising:

a pair of longitudinally extending thin wires, said wires being laterally spaced apart;

a plurality of LED elements positioned between the wires and spaced longitudinally therealong;

a plurality of thin electrical connectors electrically connecting the LED elements across the wires;

wherein the wires, LED elements, and connectors lie essentially in a plane; and

an elongated, flat, thin tape element having a thickness slightly greater than said LED elements, wherein said tape element is composed of at least partially translucent plastic, and is formed by disposing said plastic, in liquid form, around said wires, LED elements, and connectors so as to completely embed the same.

2. An illuminated tape as claimed in claim 1, wherein the plastic is flexible, wherein each LED element is an LED chip, and wherein the tape element has a thickness slightly greater than the chip.

3. An illuminated tape as claimed in claim 2, wherein the tape element has top and bottom surfaces, and an adhesive backing on one of the surfaces.

4. An illuminated tape as claimed in claim 2, wherein the plastic is transparent.

5. An illuminated tape as claimed in claim 2, wherein for each parallel connection, more than one LED chip is connected in series across the wires.

6. A method for manufacturing a weatherproof, illuminated tape comprising the steps of:

arranging a pair of elongated, thin wires so as to extend generally parallel to one another;

positioning a plurality of LED elements between the wires so as to be longitudinally spaced therealong;

connecting the LED elements electrically across the pair of elongated wires; and

completely embedding the wires, LED elements, and connectors in a liquid, at least partially translucent, plastic and molding and cooling said plastic to form an elongated, flat, thin tape element having a thickness slightly greater than said LED elements.

7. A method according to claim 6, comprising the step of providing a plurality of LED chips, wherein the LED elements are said LED chips, and wherein the plastic is molded to a thickness slightly greater than said LED chips.

8. A method according to claim 7, wherein said tape element has a bottom surface, and comprising the step of affixing an adhesive backing to said bottom surface.
