Abstract

A work light including a body defining a first end, a second end opposite the first end, a length extending between the first end and the second end, and a pivot axis extending parallel to the length. The first end includes a power button. The work light further includes a light source head pivotally coupled to the body to pivot about the pivot axis and configured to be operated by the power button. The light source head includes a planar light panel having a plurality of light emitting diodes aligned in a direction parallel to the pivot axis. The work light further includes a battery receptacle disposed on the body and configured to receive at least a portion of a battery. The battery couples to the battery receptacle by sliding into the battery receptacle along the direction parallel to the pivot axis.

Claims (28)

1. A work light comprising:

a body defining a first end, a second end opposite the first end, a length extending between the first end and the second end, and a pivot axis extending parallel to the length, wherein the first end includes a power button;

a light source head pivotally coupled to the body via a hinge to pivot about the pivot axis and configured to be operated by the power button, the light source head including a planar light panel defining a first end, a second end opposite the first end, and a length extending between the first end and the second end with the hinge positioned midway between the first end and the second end of the planar light panel, the planar light panel having a plurality of light emitting diodes aligned in a direction parallel to the pivot axis; and

a battery receptacle disposed on the body and configured to receive at least a portion of a battery, wherein the battery couples to the battery receptacle by sliding into the battery receptacle along the direction parallel to the pivot axis.

2. The work light of claim 1 , wherein the body includes two opposing sides extending between the first end and the second end, the two opposing sides are configured to be grasped by a user of the work light.

3. The work light of claim 1 , wherein the light source head is coupled to the body by a hinge, and wherein the hinge is located between the first end and the second end.

4. The work light of claim 1 , wherein the planar light panel of the light source head is surrounded by a head frame.

5. The work light of claim 4 , wherein the planar light panel is recessed relative to the head frame.

6. The work light of claim 1 , wherein the planar light panel is operable in a first mode corresponding to a first brightness level and a second mode corresponding to a second brightness level that is less than the first brightness level.

7. The work light of claim 6 , wherein the power button is actuated to select between the first mode and the second mode.

8. The work light of claim 1 , wherein the power button is actuated in a direction parallel to the pivot axis.

9. The work light of claim 1 , wherein the planar light panel is configured to be selectively powered by the battery.

10. The work light of claim 1 , wherein the light source head is configured to pivot relative to the body through an angle of rotation, wherein the angle of rotation includes 120 degrees.

11. The work light of claim 1 , further comprising the battery, wherein the battery includes a connection portion that is removably received within the battery receptacle of the body and an external portion that is disposed outside of the body when the battery is properly coupled to the body.

12. The work light of claim 1 , further comprising means for hanging the work light from a structure.

13. A work light comprising:

a body defining a first end, a second end opposite the first end, a length extending between the first end and the second end, and a back surface extending in a direction parallel to the length, wherein the first end includes a power button positioned on a top surface that is perpendicular to the back surface;

a light source head coupled to the body and configured to be operated by the power button, the light source head including a planar light panel defining a first end, a second end opposite the first end, and a length extending between the first end and the second end, the planar light panel having a plurality of light emitting diodes aligned in a direction parallel to the length of the body, the plurality of light emitting diodes are configured to emit light in a direction away from the back surface;

a hinge positioned midway between the first end and the second end of the planar light panel, the hinge pivotably coupling the body and the light source head to enable the body and the light source head to pivot relative to each other;

a battery receptacle disposed on the body and configured to receive at least a portion of a battery, wherein the battery couples to the battery receptacle by sliding into the battery receptacle along a direction parallel to the length; and

means for hanging the work light from a work surface, wherein the means for hanging is on the back surface.

14. The work light of claim 13 , wherein the planar light panel of the light source head is surrounded by a head frame.

15. The work light of claim 14 , wherein the planar light panel is recessed relative to the head frame.

16. The work light of claim 13 , wherein the planar light panel is operable in a first mode corresponding to a first brightness level and a second mode corresponding to a second brightness level that is less than the first brightness level.

17. The work light of claim 16 , wherein the power button is actuated to select between the first mode and the second mode.

18. The work light of claim 13 , wherein the power button is actuated in a direction parallel to the length.

19. The work light of claim 13 , further comprising the battery, wherein the battery includes a connection portion that is removably received within the battery receptacle of the body and an external portion that is disposed outside of the body when the battery is properly coupled to the body.

20. The work light of claim 13 , wherein the body further defines a first width measured perpendicular to the length, and wherein the light source head defines a second width that is less than the first width.
