Abstract

A portable lighting device includes a body, a lighting unit supported by the body, and a terminal block supported by the body. The terminal block is configured to connect to a power source and provide electrical energy to the lighting unit to illuminate a light emitting diode. The portable lighting device also includes a hanging cable configured to hang the body from a support structure. The hanging cable has a first end secured to the body and a second end portion opposite the first end. The portable lighting device further includes a cable clamp mechanism supported by the body. The cable clamp mechanism engages the second end portion of the hanging cable to allow adjustment of a length of the hanging cable between the first end and the cable clamp mechanism.

First claim

What is claimed is:

1. A portable lighting device comprising:
a body;
a lighting unit supported by the body, the lighting unit including a light emitting diode;
a terminal block supported by the body, the terminal block configured to connect to a power source and provide electrical energy to the lighting unit to illuminate the light emitting diode;
a hanging cable configured to hang the body from a support structure, the hanging cable having a first end secured to the body and a second end portion opposite the first end; and
a cable clamp mechanism supported by the body, the cable clamp mechanism engaging the second end portion of the hanging cable to allow adjustment of a length of the hanging cable between the first end and the cable clamp mechanism;
wherein the body further includes a retention member disposed adjacent the cable clamp mechanism, where the retention member constrains movement of the hanging cable away from the body to retain the hanging cable within the cable clamp mechanism;
wherein the retention member includes a first tab positioned on one side of the cable clamp mechanism and a second tab positioned on an opposite side of the cable clamp mechanism, and wherein the hanging cable is threaded between the body and the first tab, through the cable clamp mechanism, and between the body and the second tab.

2. The portable lighting device of claim 1 , wherein the cable clamp mechanism is supported on an outer surface of the body.

3. The portable lighting device of claim 1 , wherein the cable clamp mechanism includes a pair of rotatable cams having toothed gripping surfaces that are spaced apart to define a gap for receiving the hanging cable.

4. The portable lighting device of claim 3 , wherein each rotatable cam is rotatable between a locked configuration, in which the toothed gripping surface protrudes into the gap to engage the hanging cable, and an unlocked configuration, in which the toothed gripping surface releases the hanging cable to allow adjustment of the hanging cable.

5. The portable lighting device of claim 4 , wherein each rotatable cam is biased toward the locked configuration, and wherein the pair of rotatable cams allows the length of the hanging cable to be shortened, but not lengthened.

6. A portable lighting device comprising:
a body having an interior cavity;
a lighting unit supported by the body, the lighting unit including a light emitting diode;
a terminal block supported within the interior cavity of the body, the terminal block configured to connect to a power source and provide electrical energy to the lighting unit to illuminate the light emitting diode;
a port formed in the body in communication with the interior cavity, the port configured to allow an electrical wire to pass into the interior cavity to couple the electrical wire to the terminal block;
a wire clamp supported by the body at the port, the wire clamp being selectively movable relative to the body to engage the electrical wire passing through the port; and
a hanging cable coupled to the body, the hanging cable configured to hang the body from a support structure.

7. The portable lighting device of claim 6 , wherein the terminal block includes a power input terminal for providing electricity to the lighting unit, a power output terminal for outputting electricity that has passed through the lighting unit, and a ground terminal.

8. The portable lighting device of claim 7 , wherein the terminal block also includes a pass-through terminal, and wherein the pass-through terminal transfers electricity through the terminal block without providing the electricity to the lighting unit.

9. The portable lighting device of claim 6 , wherein the port is a first port and the wire clamp is a first wire clamp, and further comprising:
a second port defined in the body in communication with the interior cavity and spaced apart from the first port, the second port configured to allow another electrical wire to pass into the interior cavity to couple the another electrical wire to the terminal block; and
a second wire clamp supported by the body at the second port, the second wire clamp being selectively movable relative to the body to engage the another electrical wire passing through the second port.

10. The portable lighting device of claim 6 , wherein the wire clamp includes a door that selectively covers the port and an adjustment member operatively coupled to the door, and wherein the adjustment member is actuatable to move the door relative to the body.

11. The portable lighting device of claim 10 , wherein the adjustment member includes a threaded fastener.

12. The portable lighting device of claim 6 , wherein the body includes a base and a cover pivotally coupled to the base to provide access to the interior cavity.

13. The portable lighting device of claim 12 , wherein the cover includes a locking mechanism that engages the base to maintain the cover in a closed configuration.

14. A portable lighting device comprising:
a body including a base having an interior cavity, a cover movably coupled to the base to selectively provide access to the interior cavity, and an annular rim supported by the cover above the base, the annular rim defining an opening;
a lighting unit supported by the body, the lighting unit including a light emitting diode;
a lens coupled to the base of the body and surrounding the lighting unit, the lens having a lower portion opposite from the body, the lower portion having a similar shape and size as the opening defined by the annular rim;
a terminal block supported within the interior cavity of the body, the terminal block configured to connect to a power source and provide electrical energy to the lighting unit to illuminate the light emitting diode; and
a hanging cable coupled to the body, the hanging cable configured to hang the body from a support structure.

15. The portable lighting device of claim 14 , wherein the rim has a chamfered interior edge that defines the opening, and wherein the lower portion of the lens has a chamfered exterior edge that corresponds to the chamfered interior edge.

16. The portable lighting device of claim 14 , wherein the annular rim includes a notch configured to receive a fastener to support the portable lighting device on a vertical support structure.

17. The portable lighting device of claim 14 , wherein the cover includes a post that supports the annular rim apart from the cover.

18. The portable lighting device of claim 14 , wherein the lens is a solid member made of a plastic material.
