Abstract

A light assembly configured to be removably coupled to a ferromagnetic support surface includes a base with a magnetic coupling member, a battery coupled to the base, an arm pivotally coupled to the base, and a light head pivotally coupled to the arm such that a position of the light head relative to the base is adjustable. The light head includes a light-emitting element powered by the battery. The magnetic coupling member is configured to support the light assembly by magnetic attraction to the support surface.

First claim

What is claimed is:

1. A light assembly configured to be removably coupled to a ferromagnetic support surface, the light assembly comprising:
a base including a magnetic coupling member;
a battery coupled to the base;
an arm pivotally coupled to the base; and
a light head pivotally coupled to the arm such that a position of the light head relative to the base is adjustable, the light head including a light-emitting element powered by the battery,
wherein the magnetic coupling member is configured to support the light assembly by magnetic attraction to the support surface;
wherein the base includes an attachment portion having a flat surface engageable with the support surface when the light assembly is coupled to the support surface; and
wherein the base includes a handle portion extending from the attachment portion, the handle portion defining a longitudinal axis oriented at an oblique angle relative to the flat surface.

2. The light assembly of claim 1 , wherein the angle is between 95 degrees and 135 degrees.

3. The light assembly of claim 1 , wherein the handle portion includes a battery receptacle, and wherein the battery is at least partially inserted into the battery receptacle to couple the battery to the base.

4. The light assembly of claim 1 , wherein the arm includes a tray and a permanent magnet enclosed within the arm adjacent the tray.

5. The light assembly of claim 1 , wherein the light-emitting element is electrically connected to the battery through the arm.

6. The light assembly of claim 1 , further comprising a control interface for controlling operation of the light emitting element, wherein the control interface is located on the light head.

7. The light assembly of claim 1 , wherein the light-emitting element includes a plurality of LEDs.

8. The light assembly of claim 3 , wherein the battery is removable from the battery receptacle along the longitudinal axis.

9. The light assembly of claim 6 , wherein the control interface includes a first control configured to turn the light emitting element on/off, and a second control configured to adjust a brightness of the light emitting element.

10. The light assembly of claim 9 , wherein the light head includes a handle configured to be grasped by a user to adjust the position of the light head relative to the base.

11. A light assembly configured to be removably coupled to a support surface, the light assembly comprising:
a base including a coupling member configured to removably couple the base to the support surface;
a battery coupled to the base;
an arm extending from the base; and
a light head coupled to the arm, wherein the arm is movable such that a position of the light head relative to the base is adjustable, the light head including a light-emitting element powered by the battery,
wherein the base includes a handle portion configured to be grasped to disengage the coupling member from the support surface;
wherein the base includes an attachment portion having a flat surface engageable with the support surface when the light assembly is coupled to the support surface;
wherein the handle portion extends along a longitudinal axis oriented at an oblique angle relative to the flat surface; and
wherein the oblique angle is between 95 degrees and 135 degrees.

12. The light assembly of claim 11 , wherein the coupling member includes a magnet configured to magnetically couple the base to the support surface.

13. The light assembly of claim 11 , wherein the arm includes an internal honeycomb structure comprising a plurality of hexagonal cells.

14. The light assembly of claim 11 , wherein the handle portion includes a battery receptacle that removably receives at least a portion of the battery.

15. The light assembly of claim 12 , wherein the handle portion includes a battery receptacle, and wherein the battery is at least partially inserted into the battery receptacle to couple the battery to the base, and wherein the battery is removable from the battery receptacle along the longitudinal axis.

16. The light assembly of claim 13 , wherein the arm is pivotally coupled to the base, and wherein the light head is pivotally coupled to the arm opposite the base.

17. A light assembly configured to be removably coupled to a ferromagnetic support surface, the light assembly comprising:
a base including a magnetic coupling member;
an arm extending from the base, the arm including a tray and a permanent magnet within the arm adjacent the tray; and
a light head coupled to an end of the arm opposite the base, wherein the arm is movable relative to the base such that a position of the light head relative to the base is adjustable, the light head including a light-emitting element and a control interface for controlling operation of the light-emitting element,
wherein the magnetic coupling member is configured to support the light assembly by magnetic attraction to the support surface;
wherein the base includes an attachment portion having a flat surface engageable with the support surface when the light assembly is coupled to the support surface; and
wherein the base includes a handle portion extending from the attachment portion, the handle portion defining a longitudinal axis oriented at an oblique angle relative to the flat surface.

18. The light assembly of claim 17 , further comprising a battery coupled to the base, wherein the light-emitting element is powered by the battery.

19. The light assembly of claim 17 , wherein the tray is a recessed tray.

20. The light assembly of claim 14 , wherein the battery extends out of the handle when coupled to the battery receptacle.
