Patent ID: 7387406

Claim:
A method of making an illuminated signage system, comprising: providing a sign member configured according to a desired illumination shape and having a flat surface portion; providing a plurality of light emitting diode (LED) modules that are electrically interconnected to each other in an electrically parallel arrangement, each of the LED modules comprising: at least one LED; a plurality of electrically conductive contacts, the at least one LED electrically communicating with at least one of the contacts; a dielectric layer having a first side and a second side, the contacts being disposed on the first side; and a heat conductive body communicating with the second side of the dielectric layer, the heat conductive body configured to absorb heat generated by the at least one LED that flows through the dielectric layer, the heat conductive body comprising a generally flat portion disposed generally opposite the dielectric layer; providing an adhesive member configured to connect the LED module to the flat surface portion of the sign member, at least part of the heat conductive body being disposed between the dielectric layer and the adhesive member; and adhering the adhesive member of each module to a surface of the sign member so that the generally flat portion of the heat conductive body is arranged generally complementary to the flat surface portion of the sign member.
