Abstract

The invention provides, in one aspect, a work light including a housing and a plurality of light sources coupled to the housing. At least one of the light sources is movable relative to the housing to vary a lighting pattern emitted by the light sources relative to an outer periphery of the housing. The work light also includes an actuator coupled to the at least one movable light source for moving the light source relative to the housing.

Claims (12)

1. A work light comprising:

a housing;

a plurality of light sources positioned around a central axis of the housing, each of the light sources being movable relative to the housing to vary a lighting pattern emitted by the light sources relative to an outer periphery of the housing; and

a single actuator coupled to the light sources for moving the light sources relative to the housing, wherein each of the light sources includes an elongated LED strip, and wherein each of the light sources is rotatable about an axis that is substantially parallel with the central axis of the housing.

2. The work light of claim 1 , wherein the housing includes a translucent portion in which the light sources are positioned.

3. The work light of claim 1 , wherein the plurality of light sources are movable between a first orientation, in which the plurality of light sources collectively emit light surrounding the entire periphery of the housing, and a second orientation, in which the plurality of light sources collectively emit light surrounding less than the entire periphery of the housing.

4. The work light of claim 1 , further comprising a power tool battery pack for providing electrical energy to the light sources.

5. The work light of claim 1 , further comprising a switch selectively electrically connecting the battery pack and the light sources.

6. The work light of claim 1 , further comprising a fastener to clamp the housing to a stand.

7. The work light of claim 1 , further comprising a handle coupled to the housing and pivotable between a retracted position and an extended position.

8. The work light of claim 1 , further comprising a transmission interconnecting the actuator and at least one of the light sources.

9. The work light of claim 1 , wherein each of the light sources is rotatable in response to rotation of the actuator.
