7 . The area light of claim 6 , wherein the handle is accessible through an opening in the leg beam.
8 . The area light of claim 1 , wherein the base module includes a housing that is generally cuboid, wherein the leg assembly is one of a plurality of leg assemblies, and wherein the track of each leg assembly is coupled to an edge of the housing.
9 . An area light comprising:
a base module;
a mast assembly extending upward from the base module;
a light assembly coupled to the mast assembly and configured to emit light; and
a leg assembly coupled to the base module and movable between a retracted state and a deployed state, the leg assembly including
a track coupled to the base module,
a leg beam extending between a first beam end and a second beam end, the first beam end adjacent the track, the second beam end configured to engage a ground surface,
a strut extending between a first strut end and a second strut end, the first strut end adjacent the track, the second strut end pivotally coupled to the leg beam,
a first sled slidably mounted between the leg beam and the track to slide along the track within a first range, and
a second sled is slidably mounted between the strut and the track to slide along the track within a second range.
10 . The area light of claim 9 , wherein the first beam end of the leg beam is pivotally coupled to the first sled, and wherein the first strut end of the strut is pivotally coupled to the second sled.
11 . The area light of claim 9 , wherein the first sled is biased toward the second sled by a spring.
12 . The area light of claim 11 , wherein the leg assembly is selectively retained in the retracted state by a locking assembly, and wherein upon release of the locking assembly, the first sled moves toward the second sled, causing the leg assembly to move toward the deployed state.
13 . An area light comprising:
a base module having a set of wheels supporting the base module on a surface;
a battery receptacle disposed in the base module, the battery receptacle configured to receive a battery;
a drive motor supported by the base module and electrically coupled to the battery receptacle, the drive motor configured to receive power from the battery and rotate at least some of the set of wheels;
a mast assembly extending from the base module;
a light assembly coupled to the mast assembly and electrically coupled to the battery receptacle, the light assembly configured to receive power from the battery; and
a leg assembly coupled to the base module for movement between a stowed position and a deployed position, the leg assembly including
a track coupled to the base module,
a leg beam extending between a first beam end and a second beam end, the first beam end being mounted to the track for translation along the track and rotation with respect to the track, and
an adjustment mechanism for translating the leg beam with respect to the track after the leg assembly is in the deployed position;
wherein the leg assembly also includes a strut extending between a first strut end, slidably and pivotally coupled to the track, and a second strut end, pivotally coupled to the leg beam between the first beam end and the second beam end.
14 . The area light of claim 13 , wherein the set of wheels includes a pair of drive wheels operably coupled to the drive motor and a pair of non-powered caster wheels.
15 . The area light of claim 13 , wherein the base module includes a front wall, a rear wall opposite the front wall, and a handle extending from the rear wall and configured to be pushed by a user to roll the set of wheels across the surface.
