Patent ID: 8354684

Claim:
A device comprising: a first light emitting diode (LED) die; a first substrate comprising a top surface, a bottom surface and a lateral boundary, wherein the first LED die is disposed above the top surface of the first substrate and is electrically connected to a landing pad disposed on the top surface of the first substrate, and wherein the first substrate is free of any fasteners and electrical connections extending from the top surface of the first substrate to the bottom surface of the first substrate through a via in the first substrate or a mouse bite on the lateral boundary of the first substrate; and an interconnect structure comprising a contact pad, an opening and a bottom surface, wherein: the first substrate is electrically and mechanically fixedly attached to the interconnect structure solely through the contact pad on the interconnect structure which contacts the landing pad on the first substrate; the first LED is substantially centered within the opening of the interconnect structure; the interconnect structure is securely attached to a heat sink; and the bottom surface of the first substrate is thermally coupled to the heat sink by a force exerted from the interconnect structure to the first substrate.
