THREE DIMENSIONAL LIGHT EMITTING DIODE SYSTEMS, AND COMPOSITIONS AND METHODS RELATING THERETO

摘要

A flexible layered structure is disclosed having a flexible top conductive layer, a flexible bottom heat sink layer and a flexible dielectric middle layer. The combination has a longitudinal axis and a plurality of defined positions spaced along the longitudinal axis. The defined positions can be used for aligning a circuit and/or for the placement of LED lights. The flexible layered structure can be easily bent to form a LED substrate for shining light in more than one direction while efficiently removing heat arising from the LEDs.
