Abstract
A luminaire includes a stationary heat sink and an LED module adjustably coupled to the stationary heat sink. The LED module is inserted into a cavity formed within the stationary heat sink and includes a slot therein. The slot includes a first and second end. According to some exemplary embodiments, a fastening device is inserted through the slot and fixedly coupled to an interior sidewall of the stationary heat sink. The LED module is directionally adjustable by sliding the slot between the ends with respect to the fixedly coupled fastening device. The LED module includes a second heat sink which is rotatable with respect to the stationary heat sink and maintains continuous contact with the stationary heat sink along the LED module'"'"'s full rotational range. According to some exemplary embodiments, the first end is positioned lower than the second end. According to some exemplary embodiments, the slot is arcuately-shaped.
