Abstract: A flexible, self-adhesive, lighting system includes a continuous length of flexible, self-adhesive, light emissive material, cuttable into segments of light emissive material, each segment including a plurality of light emitting diodes serving as light emissive devices. The segments are electrically coupled by different shaped couplers, for forming a variety of configurations of light emissive material, and further coupled to a source of power. Each coupler includes at least two electrical conductors for conducting power from one segment of light emissive material to a coupled segment or a source of power. Each of the light emissive devices may be covered by one clear or colored lens. Alternatively, multiple light emissive devices, of the same or different color, may be covered by one lens. Further, steady or intermittent power from a power control unit may be supplied to each light emissive device for providing different lighting sequences and colors.
