Abstract

A device may include a work light configured to emit light in a first direction. A device may include a hazard light configured to emit light in a second direction. A device may include a hinge coupled between the work light and the hazard light such that the work light and the hazard light are independently rotatable relative to each other about the hinge from a storage position to a deployed position. A device may include a user interface disposed on the hazard light, the user interface including a work light actuator engageable to actuate the work light and a hazard light actuator engageable independent from the work light actuator to actuate the hazard light.

Claims (37)

1 . A light unit comprising:

a work light configured to emit light in a first direction;

a hazard light configured to emit light in a second direction;

a hinge coupled between the work light and the hazard light such that the work light and the hazard light are independently rotatable relative to each other about the hinge from a storage position to a deployed position;

a user interface including a work light actuator engageable to actuate the work light and a hazard light actuator engageable independent from the work light actuator to actuate the hazard light; and

a circuit board electrically coupled to the work light and the hazard light, and the circuit board configured to control an output of each of the work light and the hazard light via the user interface,

wherein the user interface is disposed only on the work light or the hazard light.

2 . The light unit of claim 1 , wherein the hazard light is rotatable approximately 200 degrees relative to the work light from the storage position.

3 . The light unit of claim 2 , wherein the storage position is defined by the work light and the hazard light in a back-to-back arrangement.

4 . The light unit of claim 1 , wherein the hinge defines a cavity configured to receive a battery configured to provide power to each of the work light and to the hazard light.

5 . The light unit of claim 1 , wherein the work light actuator includes at least two work light modes, and wherein the hazard light actuator includes at least two hazard light modes separate from the work light modes.

6 . The light unit of claim 5 , wherein the at least two work light modes include two or more of a low intensity mode, a medium intensity mode, and a high intensity mode.

7 . The light unit of claim 5 , wherein the at least two hazard light modes include two or more of a steady mode, a flash mode, and a tracer mode.

8 . The light unit of claim 1 , wherein the work light includes a first frame and the hazard light includes a second frame different from the first frame, and wherein at least one of the first frame and the second frame includes a magnet.

9 . The light unit of claim 1 , wherein only the work light includes an aperture configured to be gripped by a user.

10 . The light unit of claim 1 , wherein the circuit board is a first circuit board and the light unit further comprises a second circuit board electrically coupled between the first circuit board and the work light and a third circuit board electrically coupled between the first circuit board and the hazard light.

11 . A light unit comprising:

a work light including a first hinge portion through which a pivot axis extends;

a hazard light including a second hinge portion rotatably coupled to the first hinge portion about the pivot axis;

a first circuit board electrically coupled to the work light and including a user interface having a work light actuator and a hazard light actuator, the user interface disposed only on the work light or the hazard light; and

a second circuit board coupled to the hazard light;

wherein the first hinge portion and the second hinge portion cooperatively define a cavity configured to receive a power source to power each of the work light and the hazard light.

12 . The light unit of claim 11 , wherein each of the work light and hazard light is pivotable about the pivot axis up to approximately 200 degrees from a storage position in which the work light and the hazard light are in a back-to-back arrangement.

13 . The light unit of claim 11 , further comprising a third circuit board electrically coupled between the first circuit board and the work light, wherein the second circuit board is electrically coupled between the first circuit board and the hazard light.

14 . A light unit comprising:

a work light fixture including:

a work light frame defining a plurality of frame segments and at least one aperture formed between the frame segments;

a first LED disposed at a center portion of the frame segments; and

a first hinge portion coupled to at least one of the plurality of frame segments; and

a hazard light fixture including:

a hazard light frame having a second hinge portion pivotably coupled to the first hinge portion, the hazard light frame further having a first portion defining an outer periphery of the hazard light frame and a second portion spaced from the first portion toward a center of the hazard light frame;

a channel defined between the first portion and the second portion;

a second LED disposed within the channel; and

a circuit board supported by the second portion, the circuit board configured to control an output of each of the first LED and the second LED;

wherein the first hinge portion and the second hinge portion cooperatively define a cylindrical body configured to receive a power source.

15 . The light unit of claim 14 , wherein the circuit board includes a user interface having a work light actuator and a hazard light actuator that are independently actuatable to control the work light and the hazard light.

16 . The light unit of claim 15 , wherein the work light actuator is configured to switch the work light between at least two different work light modes, and wherein the hazard light actuator is configured to switch the hazard light between at least two different hazard light modes.
