Abstract

A work light assembly remotely positionable by means of a radio frequency transmitter signaling a motion controller driving a linear actuator. The light source is mounted on a pivoting boom that is in turn mounted to an upright post that telescopes up or down by means of manual controls interfaced with the controller, or by way of an RF transmitter commanding the controller. Motive properties such as maximum telescoping travel speed are preset at the controller.

Claims

1. A remotely positionable work-light comprising:

a removable post assembly have a telescoping member within a upright conduit; and

,

a movable boom affixed to the telescoping member; and

,

a movable light housing affixed to one end of the boom; and

,

a radio frequency responsive controller having a circuit and power source; and

,

a linear actuator for the vertical movement of the telescoping member and responsive to the controller, and,

a radio frequency transmitter; and

,

a rollable and collapsible stand supportive of the post assembly, the linear actuator and the controller; and

,

at least one power cord.

2. The remotely positionable work-light according to claim 1 in which the radio frequency transmitter signals the controller to actuate the linear actuator to move the telescoping member up and down in order to raise and lower the light housing as required.

3. The remotely positionable work-light according to claim 1 in which manual switches interfacing with the controller actuate the linear actuator to move the telescoping member up and down in order to raise and lower the light source as required.

4. The remotely positionable work-light according to claim 1 in which the controller has at least one telescoping speed setting.

5. The remotely positionable work-light according to claim 1 in which the controller has a plurality of telescoping speed settings.

6. The remotely positionable work-light according to claim 1 in which a ratio between the power applied to the linear actuator for one direction of extension versus the other direction can be set.

7. The remotely positionable work-light according to claim 1 in which the time before changes in the speed of the linear actuator can be set.

8. The remotely positionable work-light according to claim 1 in which the light source is tillable by means of a variable speed motor driven by the controller.

9. The remotely positionable work-light according to claim 1 in which the linear actuator is an electrically powered jack-screw type.

10. The remotely positionable work-light according to claim 1 in which the power source is 110-120 VAC.

11. The remotely positionable work-light according to claim 1 in which the power source is 12-24 VDC.

12. The remotely positionable work-light according to claim 1 in which the power source is switchable between 110-120 VAC and 12-24 VDC.
