Abstract

A utility light includes a housing having a rear wall attached to a forwardly extending peripheral wall to form a front opening, a stand rotatably attached to the housing to permit the light to rotate relative to a support surface, a plurality of LEDs mounted in the housing facing the front opening, and a lens removably attached to the housing and closing the front opening. The LEDs are divided between an inner circuit board and a plurality of outer circuit boards adjacent the edges of the inner board. The outer circuit boards and corresponding portions of the lens are angled relative to the inner circuit board and a central portion of the lens. The light can be operated to light all and less than all of the LEDs.

Claims

1. A utility light comprising:

a generally square housing having a rear wall and a peripheral wall extending forwardly from said rear wall forming a front opening;

a plurality of LEDs mounted in said housing facing said front opening;

a lens removably attached to said housing and closing said front opening, said lens including a central portion having a plane extending generally parallel to said rear wall and a plurality of outer portions extending from said central portion and angled relative to said plane of said central portion;

a stand attached to said housing for supporting the utility light on a support surface and permitting rotation of said housing about a predetermined axis;

a first group of less than all of said LEDs being mounted on an inner circuit board assembly retained in said housing;

said LEDs not included in said first group being mounted on a plurality of outer circuit board assemblies positioned around said inner circuit board assembly; and

each of said outer circuit board assemblies and an associated one of said outer portions of said lens extending in generally parallel planes angled relative to a plane of said rear wall.

2. The light according to claim 1 wherein said rear wall, said inner circuit board assembly and said central portion of said lens extend in generally parallel planes.

3. The light according to claim 1 including a switch connected to said plurality of LEDs for selectively applying electrical power to said LEDs of said first group in a first switch mode and applying electrical power to a second group of said LEDs in a second switch mode, said second group being one of all of said LEDs and all of said LEDs not included in said first group.

4. The light according to claim 1 wherein a second group of said LEDs includes all of said LEDs not included in said first group.

5. The light according to claim 1 wherein said rear wall and a top portion of said peripheral wall have a recess formed therein, said recess having a bottom wall with an aperture formed therein, and including a switch mounted in said aperture and being connected to said LEDs for selectively applying electrical power to light said LEDs.

6. The light according to claim 1 wherein a first group of less than all of said LEDs is mounted on an inner circuit board assembly retained in said housing and all of said LEDs not included in said first group are mounted on a plurality of outer circuit board assemblies positioned adjacent edges of said inner circuit board assembly.

7. The light according to claim 6 wherein said rear wall, said inner circuit board assembly and said central portion of said lens extend in generally parallel planes and each of said outer circuit board assemblies and an associated one of said outer portions of said lens extend in generally parallel planes angled relative to the plane of said rear wall.

8. The light according to claim 7 wherein said housing has at least one inner bracket supporting said inner circuit board assembly and at least one outer bracket with an angled upper surface supporting each of said outer circuit board assemblies.

9. The light according to claim 1 including a reflector member mounted in said housing adjacent said LEDs.

10. The light according to claim 1 wherein said stand is generally U-shaped providing a grip for a human hand to carry the light.

11. The light according to claim 10 wherein said stand includes a pair of support surface engaging feet.

12. The light according to claim 10 wherein said stand includes a bar having a leg extending from opposed ends thereof, said legs being rotatably attached to said housing, and at least one aperture formed in said bar for receiving a fastener to mount the light to a support surface.

13. A utility light comprising:

a generally square housing having a rear wall and a peripheral wall extending forwardly from said rear wall forming a front opening;

a plurality of LEDs mounted in said housing facing said front opening;

a lens removably attached to said housing and closing said front opening, said lens including a central portion having a plane extending generally parallel to said rear wall and a plurality of outer portions extending from said central portion and angled relative to said plane of said central portion;

a stand attached to said housing for supporting the utility light on a support surface and permitting rotation of said housing about a predetermined axis;

a first group of less than all of said LEDs being mounted on an inner circuit board assembly retained in said housing and all of said LEDs not included in said first group being mounted on a plurality of outer circuit board assemblies positioned adjacent edges of said inner circuit board assembly; and

said rear wall, said inner circuit board assembly and said central portion of said lens extending in generally parallel planes and each of said outer circuit board assemblies and an associated one of said outer portions of said lens extending in generally parallel planes angled relative to the plane of said rear wall.

14. The light according to claim 13 wherein said housing has at least one inner bracket supporting said inner circuit board assembly and at least one outer bracket with an angled upper surface supporting each of said outer circuit board assemblies.
