Abstract

A portable utility light has a hollow housing formed of releasably joined front and rear housing halves with a lens opening. A plurality of LEDs is mounted in the housing adjacent the lens opening and positioned in rows and columns. A reflector member has a plurality of cone-shaped apertures each receiving one of the LEDs with a facing reflective surface. A transparent lens member is mounted in the lens opening to permit light generated from the LEDs to exit the housing.

Claims

1. A portable utility light, comprising:

a hollow housing having a lens opening formed therein;

a plurality of LEDs mounted in said hollow housing adjacent said lens opening;

a reflector member mounted in said housing and having a plurality of apertures of cone-shaped profile formed therein, each of said apertures receiving an associated one of said LEDs; and

a transparent lens member mounted in said lens opening permitting light generated from said LEDs to exit said housing.

2. The light according to claim 1 wherein said housing is formed by a front housing half releasably attached to a rear housing half.

3. The light according to claim 1 wherein said housing is generally arcuate in a horizontal plane.

4. The light according to claim 1 wherein said LEDs are mounted on a circuit board in rows and columns.

5. The light according to claim 1 wherein said reflector member has a reflective surface facing said lens member.

6. The light according to claim 1 including a battery disposed in said housing and connected to said LEDs by a switch.

7. The light according to claim 6 including an electrical plug mounted to said housing and connected to said battery, said electrical plug being adapted to connect to an external power source to recharge said battery.

8. The light according to claim 6 wherein said battery is a DC battery and including a transformer means connected to said battery for recharging said battery.

9. The light according to claim 1 including a hook member disposed in a recess formed in an exterior surface of said housing and being rotatable between a stored position in said recess and an extended position.

10. The light according to claim 9 wherein said hook member is attached to said housing by a ball and socket connection permitting said hook member to rotate about a longitudinal axis of said hook member.

11. The light according to claim 1 including a lanyard attached to said housing.

12. The light according to claim 1 including at least one handle cushion attached to said housing.

13. The light according to claim 1 including a carrying case for receiving and retaining said housing.

14. The light according to claim 1 wherein said lens member has a plurality of focusing portions formed thereon facing said LEDs for focusing light generated by said LEDs.

15. A portable utility light, comprising:

a hollow housing having a lens opening formed therein;

a plurality of LEDs mounted in said hollow housing adjacent said lens opening;

a battery mounted in said housing and electrically connected to operate said LEDs;

a reflector member mounted in said housing and having a plurality of apertures of cone-shaped profile formed therein, each of said apertures receiving an associated one of said LEDs; and

a transparent lens member mounted in said lens opening permitting light generated from said LEDs to exit said housing.

16. The light according to claim 15 wherein said battery is connected to said LEDs by a switch and including an electrical plug mounted to said housing and connected to said battery, said electrical plug being adapted to connect to an external power source to recharge said battery.

17. A portable utility light, comprising:

a hollow housing having a lens opening formed therein;

a pair of handle cushions attached to opposite sides of said housing;

a plurality of LEDs mounted in said hollow housing adjacent said lens opening;

a reflector member mounted in said housing and having a plurality of apertures of cone-shaped profile formed therein, each of said apertures receiving an associated one of said LEDs; and

a transparent lens member mounted in said lens opening permitting light generated from said LEDs to exit said housing.

18. The light according to claim 17 including a battery disposed in said housing and connected to said LEDs by a switch, and an electrical plug mounted to said housing and connected to said battery, said electrical plug being adapted to connect to an external power source to recharge said battery.

19. The light according to claim 17 wherein said housing is formed by a front housing half releasably attached to a rear housing half.

20. The light according to claim 17 wherein said LEDs are mounted on a circuit board in rows and columns.
