Abstract

A work light for work or task areas which uses light-emitting diodes (LEDs) as the source of light. LED clusters are mounted on a circuit board which is located in a housing. The LED work lights may be powered by conventional 120 or 240-volt electrical outlets, a DC generator, a battery, a battery pack, or a car adapter.

Claims

1. A work light comprising:

a handle;

an elongated transparent cover mounted on said handle, said cover having a longitudinal axis;

a plurality of LEDs disposed in said transparent cover, said LEDs generating light rays which are directed at right angles to said longitudinal axis, said LEDs mounted on a mounting member; and

a transparent housing, said housing mounted on said cover along said longitudinal axis, opposite said handle, said housing including a light source.

2. The work light of claim 1 wherein said light source comprises a second plurality of LEDs.

3. The work light of claim 2 and further including a second mounting member for mounting said second plurality of LEDs.

4. A work light comprising:

a handle;

an elongated transparent cover mounted on said handle, said cover having a longitudinal axis;

a light source disposed in said cover for generating first rays of light, said light directed at right angles to said longitudinal axis;

a transparent housing mounted on said cover; and

a plurality of LEDs disposed in said housing, said LEDs generating light rays directed along said longitudinal axis.

5. The work light of claim 4 wherein said light source comprises a fluorescent lamp.

6. The work light of claim 4 wherein said light source comprises a second plurality of LEDs.

7. The work light of claim 4 wherein said plurality of LEDs are mounted on a mounting member.

8. The work light of claim 6 wherein said plurality of LEDs are mounted on a first mounting member, and said second plurality of LEDs are mounted on a second mounting member.
