Abstract

A cargo lamp assembly for vehicles includes a white light emitting diode having an aperture for emitting a light beam in horizontal and vertical planes of about 120°, and a lens for receiving the beam and reducing the beam in the horizontal plane to about 60° and reducing the beam in the vertical plane to about 60°.

Claims

1. A cargo lamp assembly for vehicles, the assembly comprising:

a white light emitting diode (LED) having an aperture for emitting a light beam in an arc of about 120°

in horizontal and vertical planes; and

a lens for receiving the beam and reducing the beam in a horizontal plane to about 60° and

reducing the beam in a vertical plane to about 60°

, the LED aperture includes a horizontal aperture component adapted for emitting the light beam extending 60°

to the left and 60°

to the right of a beam axis in the horizontal plane and a vertical aperture component for emitting the light beam extending 60°

above the beam axis and 60°

below the beam axis in the vertical plane; and

wherein said lens is adapted to configure the light beam to an upper boundary in the vertical plane deflected about 10°

downwardly relative to the horizontal plane and a lower boundary in the vertical plane extending downwardly about 70°

relative to the horizontal plane.

2. The cargo lamp in accordance with claim 1 wherein said LED is disposed about halfway between said lens in the horizontal plane and a focal point of said lens.

3. The cargo lamp in accordance with claim 1 wherein said LED is disposed at about a focal point of said lens in the vertical plane.

4. The cargo lamp in accordance with claim 2 wherein said LED is disposed at about a focal point of said lens in the vertical plane.

5. The cargo lamp in accordance with claim 1 wherein said lens is a clear lens.

6. The cargo lamp in accordance with claim 5 wherein said LED is at least an 18 lumen LED and said lens emits at least about 10 candela.
