Patent ID: 7999450

Claim:
An electroluminescent module, comprising: a module substrate comprising an opening, a first surface, a first patterned electrode disposed on the first surface, and a recess foamed on the first surface to surround the opening; a thermal-conducting carrier substrate comprising a carrying element and a second patterned electrode disposed on the carrying element, wherein the carrying element is disposed opposite to the first surface of the module substrate, and the second patterned electrode is disposed facing to and electrically connected to the first patterned electrode; and a light-emitting element located at the opening of the module substrate, disposed on the thermal-conducting carrier substrate, comprising a first electrode and a second electrode, both of which are respectively electrically connected to corresponding portions of the second patterned electrode of the thermal-conducting carrier substrate, and comprising a package material without covering the module substrate, wherein the recess fixes the thermal-conducting carrier substrate so that a heat dissipating element is tightly connected to the thermal-conducting carrier substrate.
