The invention relates to an illumination apparatus (100), comprising an LED-based light source (150) mounted to a thermally conductive substrate (130, 420), the thermally conductive substrate having a recess (457) formed therein proximate to the LED-based light source. A printed circuit board (175) has a tab (456) for insertion into the recess (457) formed in the thermally conductive substrate. A temperature sensor (416) is disposed on the tab of the printed circuit board (175) such that when the printed circuit (175) board is inserted into the recess (457) the temperature sensor (416) is embedded in the thermally conductive substrate (130, 420) proximate to the LED-based light source.
