Abstract:
A light emitting diode (LED) module includes a base that is conductive and is selectively covered with an insulative layer. The base can include a connecting flange and a light emitting region. Traces are provided on the insulative coating and can be used to connect LEDs positioned on the light emitting region to pads on the connecting flange. The connecting flange can be offset in angle and/or position from the base and can be configured to provide a contact shape suitable to mate with a connector in a polarized manner. The base can be shaped so as to provide the desired functionality.
