Lighting device for an aerial work platform
A battery powered lighting device is configured to be releasably attached to a lift bucket having sidewalls and an upper lip extending from uppermost portions of the sidewalls. The lighting device includes a main housing, a securing member that cooperates with the main housing to secure the device to an aerial work platform, a main light mounted to the main housing and located to illuminate areas outside of the lift bucket, and an interior light located to illuminate an interior of the lift bucket.
1. A battery powered lighting device configured to be releasably attached to an aerial work platform in the form of a lift bucket having sidewalls and an upper lip extending from uppermost portions of the sidewalls, the lighting device comprising:
a main housing comprising:
a battery mount configured to mount a battery to power the lighting device,
a first securing surface configured to engage a sidewall or the upper lip of the lift bucket, and
an upper housing portion configured to be located above the upper lip of the lift bucket with the first securing surface engaged against a sidewall or the upper lip of the lift bucket;
a securing member comprising a second securing surface, the securing member extending from the upper housing portion to locate the second securing surface to engage a surface of a sidewall or the upper lip of the lift bucket on an opposite side from a surface of the sidewall or the upper lip engaged by the first securing surface;
a main light mounted to the main housing and located to illuminate areas outside of the lift bucket; and
an interior light mounted on at least one of the upper housing portion and the securing member and located to illuminate an interior of a lift bucket with the lighting device attached to a sidewall or the upper lip of the lift bucket.
2. The lighting device of claim 1 wherein the interior light is mounted on the securing member and fixed against movement relative to the securing member.
3. The lighting device of claim 1 wherein the main light is mounted to the main housing to move relative to the main housing between a lower position wherein the main light is positioned below the upper housing portion and an upper position wherein the main light is positioned above the upper housing portion.
4. The lighting device of claim 1 wherein the main light is mounted to pivot about a first axis between the lower and upper positions.
5. The lighting device of claim 1 wherein the battery mount comprises a compartment that encloses a battery mounted in the battery mount.
6. The lighting device of claim 1 wherein the battery mount comprises a releasable connection to allow a battery to be releasably connected to the lighting device.
7. The lighting device of claim 1 further comprising a battery mounted in the battery mount and operably connected to power the lighting device, and wherein the main light is an array of light emitting diodes.
8. The lighting device of claim 1 wherein the securing member is mounted to the upper housing portion to move between:
an open position wherein a sidewall or the upper lip of the lift bucket can be inserted between the first and second securing surfaces, and
a clamping position wherein the sidewall or the upper lip is clamped between the first and second securing surfaces with the upper housing portion located above the lip of the lift bucket.
9. The lighting device of claim 3 wherein the main light is further mounted to move relative to the main housing between at least a forward facing position and a sideward facing position with the main light located in the lower position and with the main light located in the upper position.
10. The lighting device of claim 4 wherein the main light is further mounted to pivot about a second axis between a forward facing position and a sideward facing position.
11. The lighting device of claim 8 wherein the securing member is mounted to the upper housing to translate relative to the first securing surface between the open and clamping positions.
12. The lighting device of claim 8 wherein the securing member is biased toward the open position.
13. The lighting device of claim 8 further comprising a spring mounted between the upper housing portion and the securing member and configured to bias the securing member toward the open position, and wherein the securing member is mounted to the upper housing to translate relative to the first securing surface.
14. The lighting device of claim 13 further comprising a releasable ratchet mechanism mounted between the securing member and the upper housing portion and configured to releasably retain the securing member in the clamping position, the ratchet mechanism comprising:
an elongate, multi-toothed rack mounted to one of the securing member and the upper housing portion, and
a pawl mounted to the other of the securing member and the upper housing portion.
15. A battery powered lighting device configured to be releasably attached to an aerial work platform in the form of a lift bucket having sidewalls and an upper lip extending from uppermost portions of the sidewalls, the lighting device comprising:
a main housing comprising:
a battery mount configured to mount a battery to power the lighting device,
a first clamp surface configured to engage a sidewall or the upper lip of the lift bucket, and
an upper housing portion configured to be located above the upper lip of the lift bucket with the first clamp surface engaged against a sidewall or the upper lip of the lift bucket;
a clamp member comprising a second clamp surface, the clamp member mounted to the upper housing portion to move between an open position wherein a sidewall or the upper lip of the lift bucket can be inserted between the first and second clamp surfaces and a clamping position wherein the sidewall or the upper lip is clamped between the first and second clamp surfaces with the upper housing portion located above the lip of the lift bucket;
a main light mounted to the main housing and located to illuminate areas outside of the lift bucket; and
an interior light mounted on at least one of the upper housing portion and the clamp member and located to illuminate an interior of a lift bucket with the lighting device attached to a sidewall or the upper lip of the lift bucket.
16. The lighting device of claim 15 wherein the interior light is mounted on the clamp member and fixed against movement relative to the clamp member.
17. The lighting device of claim 15 wherein the main light is mounted to the main housing to move relative to the main housing between a lower position wherein the main light is positioned below the upper housing portion and an upper position wherein the main light is positioned above the upper housing portion.
18. The lighting device of claim 17 wherein the main light is further mounted to move relative to the main housing between at least a forward facing position and a sideward facing position with the main light located in the lower position and with the main light located in the upper position.
19. The lighting device of claim 17 wherein the main light is mounted to pivot about a first axis between the lower and upper positions.
20. The lighting device of claim 19 wherein the main light is further mounted to pivot about a second axis between a forward facing position and a sideward facing position.
