Patent ID: 8596821

Claim:
A light emitting diode (LED) light engine adapted for use in a LED light bulb, the LED light engine comprising: a substrate having patterned thereon at least one electrical trace and comprising at least one bend therein arranged to form multiple non-coplanar LED mounting surfaces of a substantially rigid upright support structure, wherein the substrate comprises multiple connectors extending beyond at least some LED mounting surfaces of the multiple non-coplanar LED mounting surfaces, and wherein the connectors are arranged for insertion into multiple recesses or compression fittings of a base element in conductive thermal communication with an externally accessible heatsink arranged between a threaded contact-defining end cap and a light-transmissive cover of a LED light bulb; and a plurality of LEDs mounted to LED mounting surfaces of the substrate, arranged in electrical communication with the at least one trace, and arranged in conductive thermal communication with at least portions of the substrate.
