Abstract
A LAM/ICM assembly comprises an integrated control module (ICM) and an LED array member (LAM). In a first aspect, active circuitry is embedded in the ICM. The circuitry monitors LED operation, controls and supplies power to the LEDs, and communicates information into and out of the assembly. A thermal insulator is disposed between the ICM and a heat sink outside the lateral boundary of the LAM. In a second aspect, a lighting system comprises an AC-to-DC converter and a LAM/ICM assembly. The AC-to-DC converter outputs a substantially constant current or voltage. The magnitude of the current or voltage is adjusted by a signal output from the LAM/ICM. In a third aspect, the ICM includes a built-in switching DC-to-DC converter. An AC-to-DC power supply supplies a roughly regulated supply voltage. The switching converter within the LAM/ICM receives the roughly regulated voltage and supplies a regulated LED drive current to its LEDs.
