Abstract

An adjustable light includes a knock down base frame, a vertical frame, which supports a boom arm, which in turn supports a light fixture. The light fixture is supported on the boom arm by a fixture mount that provides five degrees of freedom of movement of the light fixture relative to the boom arm. The boom arm is pivotally mounted to the vertically adjustable frame, thereby providing two additional degrees of freedom to the light fixture relative to the ground. The base frame includes two legs that are movably secured to the base frame. The base frame and the legs include wheels, the wheel supports being movably mounted to the frame and legs to allow for free movement on any planar surface on which the adjustable light is supported. The boom arm and the shield of the light fixture include bumpers to prevent damage by inadvertent contact to a surface. The lens in the fixture is replaceable to allow the user to use different lenses as dictated by the job requirements. A typical lens includes a substantially opaque section approximately one inch wide that is positioned in the center of the lens and runs the length of the lens.

Claims

1. An adjustable light comprising:

a base frame;

an adjustable height vertical frame releasably mounted to said base frame;

a boom arm pivotally mounted to an upper portion of said vertical frame and including a clamp lock, including a pair of concave pressure plates, a threaded fastener and a cap handle thus providing infinitely adjustable position locking of the boom arm on said vertical frame;

a light fixture; and

a fixture mount slideably and rotateably mounted on said boom arm, the fixture mount supporting said tight fixture.

2. A light as in claim 1, wherein said base frame includes at least two legs that are moveably mounted to said base frame.

3. A light as in claim 2, wherein said base frame includes at least two wheels to facilitate transport of said base frame.

4. A light as in claim 2 wherein each of said at least two legs includes a wheel to facilitate transport of said base frame when said legs are mounted thereto.

5. A light as in claim 2, wherein said wheels of said at least two legs can be movably positioned relative to said base frame.

6. A light as in claim 1, wherein said boom arm includes an end disk positioned at one end thereof, the end disk captured between a pair of ears on said vertical frame, said pair of concave pressure plates positioned on the outside of and adjacent to said pair of ears.

7. A light as in claim 1, wherein said light includes a bumper strip mounted to a peripheral edge of a lamp shield.

8. A light as in claim 1, wherein said boom arm includes a bumper pad positioned on a distal end thereof.

9. A light as in claim 1, wherein said fixture mount supports said light fixture by a ball and socket joint.

10. A light as in claim 9, wherein said fixture mount includes a split collar and a tension device enabling adjustable tension on said ball of said ball and socket joint.

11. A light as in claim 10, wherein said tension device is comprised of a threaded fastener.

12. A light as in claim 1, wherein said fixture mount includes a friction lock enabling said fixture mount to be releasably positioned on said boom arm.

13. A light as in claim 1, wherein said light fixture includes a shield with a base angle between 20°

and 30°

relative to a lens.

14. A light as in claim 13, wherein said base angle is 25°

.

15. A light as in claim 1, wherein said light fixture includes a lens with a substantially opaque area in the center thereof and runs the length of said lens.

16. A light as in claim wherein said substantially opaque area is between 0.75 inches and 1.25 inches wide.

17. A light as in claim 16, said substantially opaque are is one inch wide.

18. An adjustable light comprising:
