Abstract:
A light emitting diode (LED) module for mounting on a heat conducting surface that is substantially larger than the module, the module comprising:a plurality of LEDs, each LED having at least one lead; and a circuit board, the circuit board comprising: a thin dielectric sheet; a plurality of electrically-conductive contacts on a first side of the dielectric sheet, each of said plurality of contacts being configured to mount a lead of an LED such that said plurality of LEDs is electrically connected; and a heat conductive body on a second side of said sheet, said body having a first portion in thermal communication with the plurality of contacts through said dielectric sheet, said first portion of said body having a surface area substantially larger than a contact area between the contacts and the dielectric sheet, said body having a second portion adapted to provide thermal contact with the heat conducting surface, the second portion having a surface generally complementary to the heat conducting surface, whereby heat is transferred from the module to the heat conducting surface.
