Abstract

A lighting device ( 10 ) is provided which uses multiple LEDs to illuminate a target area. The lighting device includes first and second light emitting diodes ( 24, 26 ) spaced apart from each other. A first convex magnifier lens ( 34 ) is arranged in a light path of the first light emitting diode ( 24 ) for focusing light onto a target area. A second convex magnifier lens ( 36 ) is arranged in a light path of the second light emitting diode ( 26 ) for focusing light onto the same target area. The first and second magnifier lenses ( 34, 36 ) are supported relative to the first and second light emitting diodes ( 24, 26 ), respectively, by a cover ( 32 ).

Claims (35)

1. A lighting device comprising:

a housing;

a first light emitting diode located on the housing;

a second light emitting diode located on the housing and spaced from the first light emitting diode;

a first tilting magnifier lens arranged in a light path of the first light emitting diode for focusing a first light beam onto a target area;

a second tilting magnifier lens arranged in a light path of the second light emitting diode for focusing a second light beam onto the target area;

a rear housing coupled to a back side of the housing, the rear housing having a battery compartment;

a cover disposed over a front of the housing, the cover supporting the first and second tilting magnifier lenses relative to the first and second light emitting diodes; and

a third light emitting diode located between the first and the second light emitting diodes, wherein a light path of the third light emitting diode projects through a region of the cover disposed between the first and second tilting magnifier lenses.

2. The lighting device as defined in claim 1 , wherein the front housing is pivotally connected to the rear housing to allow the front housing and the light emitting diodes to be moved relative to the rear housing.

3. The lighting device as defined in claim 1 , wherein the third light emitting diode provides a flood light.

4. The lighting device as defined in claim 1 , wherein the third light beams has a field of view of about forty degrees.

5. The lighting device of claim 1 , wherein the first and second light beams substantially overlap.

6. The lighting device of claim 1 , wherein a substantial amount of light emitted by the third light emitting diode does not traverse a lens.

7. The lighting device of claim 1 , wherein the third light emitting diode is red colored.

8. The lighting device of claim 7 , wherein the first and second light emitting diodes are white colored.

9. A lighting device comprising:

a front housing;

a first light emitting diode located on the front housing;

a second light emitting diode located on the front housing and spaced from the first light emitting diode;

a center of a first lens arranged in a central axis of a light path of the first light emitting diode for focusing a first light beam onto a target area;

a center of a second lens arranged in a central axis of a light path of the second light emitting diode for focusing a second light beam onto the target area;

a rear housing coupled to a back side of the front housing, the rear housing having a battery compartment;

a cover disposed over a front of the front housing, the cover supporting the first and second lenses relative to the first and second light emitting diodes; and

a third light emitting diode located between the first and the second light emitting diodes, wherein a light path of the third light emitting diode projects through a region of the cover disposed between the first and second lenses.

10. The lighting device of claim 9 , wherein the first and second lenses are magnifying lenses.

11. The lighting device of claim 9 , wherein the cover supports the first and second lenses in a tilt arrangement with respect to the target area.

12. The lighting device of claim 9 , wherein the first and second light beams substantially overlap at the target area.

13. The lighting device of claim 9 , wherein a substantial amount of light emitted by the third light emitting diode does not traverse a lens.

14. The lighting device of claim 9 , wherein the front housing is pivotally connected to the rear housing to allow the front housing and the light emitting diodes to be moved relative to the rear housing.

15. The lighting device of claim 9 , wherein the third light emitting diode provides a flood light.

16. The lighting device of claim 9 , wherein the third light beams has a field of view of about forty degrees.

17. The lighting device of claim 9 , wherein the third light emitting diode provides a red light.

18. The lighting device of claim 9 , wherein the front housing is rotatable about a horizontal axis relative to the rear housing.

19. The lighting device of claim 18 , further comprising a hinge assembly on the horizontal axis that couples the front housing and the rear housing.
