Abstract

A utility light has a dual fluorescent lamp assembly mounted in a housing with a removable lens for ease of lamp replacement. The lens is releasably retained at an upper end by a locking tab. The housing has a swivel hook, a handle cushion, a housing cushion at the upper end, and a bottom cushion at a lower end. The lamp assembly is powered by a battery pack assembly releasably mounted in a handle portion of the housing for removal and insertion into a charging stand.

Claims

1. A rechargeable fluorescent utility light comprising:

a light housing having an upper light portion and a lower handle portion, said light portion having a lens opening and said handle portion being sized for gripping by a human hand;

a lens assembly closing said lens opening and being releasably attached to said light housing;

a fluorescent lamp assembly mounted in said light portion adjacent said lens assembly for generating light through said lens assembly;

a battery pack assembly releasably mounted in said handle portion;

a ballast mounted in said light housing for converting DC power to AC power; and

a switch means connected in series with said ballast between said battery pack assembly and said fluorescent lamp assembly for selectively connecting said battery pack assembly to said fluorescent lamp assembly to generate the light.

2. The utility light according to claim 1 wherein said light housing is shaped to stand upright when a lower end of said handle portion is placed on a supporting surface.

3. The utility light according to claim 1 including at least one of a housing cushion attached at an upper end of said light portion and a bottom cushion attached at a lower end of said handle portion.

4. The utility light according to claim 1 including a handle cushion attached to said handle portion.

5. The utility light according to claim 1 wherein said battery pack assembly includes locking means engaging said handle portion and preventing removal of said battery pack assembly from said handle portion.

6. The utility light according to claim 5 wherein said locking means includes a locking slide assembly spring biased into engagement with said handle portion and connected to an exposed slide tab moveable between a locked position and an unlocked position whereby when said slide tab is moved to said unlocked position, said locking slide assembly is disengaged from said handle portion to permit removal of said battery pack assembly from said handle portion.

7. The utility light according to claim 1 including at least one contact spring mounted in said handle portion for biasing said battery pack assembly to extend from said handle portion.

8. The utility light according to claim 1 wherein said battery pack assembly includes a housing retaining at least one battery cell and a front cover releasably attached to said housing for removing said at least one battery cell.

9. The utility light according to claim 1 wherein said battery pack assembly includes a housing retaining at least one battery cell and a rear cover attached to said housing for electrically connecting said at least one battery cell to said switch means, and including a charging stand for electrically connecting said at least one battery cell to a source of charging power when said battery pack assembly is removed from said handle portion and is inserted into said charging stand.

10. The utility light according to claim 1 wherein said light portion has a swivel hook mounted thereon.

11. A rechargeable fluorescent utility light comprising:

a light housing having an upper light portion and a lower handle portion, said light portion having a lens opening and said handle portion being sized for gripping by a human hand, said light housing being shaped to stand upright when a lower end of said handle portion is placed on a supporting surface;

a lens assembly closing said lens opening and being releasably attached to said light housing;

a fluorescent lamp assembly mounted in said light portion adjacent said lens assembly for generating light through said lens assembly;

a battery pack assembly releasably mounted in said handle portion including a housing retaining at least one battery cell, a front cover releasably attached to said housing for removing said at least one battery cell, and a rear cover attached to said housing for electrically connecting said at least one battery cell to said fluorescent lamp assembly;

a ballast mounted in said light housing for converting DC power to AC power; and

a switch means connected in series with said ballast between said battery pack assembly and said fluorescent lamp assembly for selectively connecting said battery pack assembly to said fluorescent lamp assembly to generate the light.

12. The utility light according to claim 11 including at least one of a housing cushion attached at an upper end of said light portion and a bottom cushion attached at said lower end of said handle portion.

13. The utility light according to claim 11 including a handle cushion attached to said handle portion.

14. The utility light according to claim 11 wherein said battery pack assembly includes locking means engaging said handle portion and preventing removal of said battery pack assembly from said handle portion.

15. The utility light according to claim 14 wherein said locking means includes a locking slide assembly spring biased into engagement with said handle portion and connected to a slide tab exposed at said front cover and moveable between a locked position and an unlocked position whereby when said slide tab is moved to said unlocked position, said locking slide assembly is disengaged from said handle portion to permit removal of said battery pack assembly from said handle portion.

16. The utility light according to claim 11 including at least one contact spring mounted in said handle portion for biasing said battery pack assembly to extend from said handle portion.

17. The utility light according to claim 11 wherein said light portion has a swivel hook mounted thereon.

18. A rechargeable fluorescent utility light comprising:

a light housing having an upper light portion and a lower handle portion, said light portion having a lens opening and said handle portion being sized for gripping by a human hand;
