Abstract

A headlamp includes a strap, a bracket coupled to the strap, and a first lighting assembly pivotally coupled to the bracket and including a first light housing enclosing a first LED, a battery housing enclosing a battery configured to power the first LED, and a first actuator operable to toggle the first lighting assembly between a first plurality of operating modes. The headlamp also includes a second lighting assembly coupled to the strap and having a plurality of second LEDs and a second actuator operable to toggle the second lighting assembly between a second plurality of operating modes such that the lighting assemblies are operable independently. A wire extends between the lighting assemblies to provide power from the battery to the plurality of second LEDs. The second lighting assembly extends along more than 50% of a circumference of the strap and follows a curvature of the strap.

First claim

What is claimed is:

1. A headlamp comprising:
a strap;
a bracket coupled to the strap;
a first lighting assembly pivotally coupled to the bracket, the first lighting assembly including
a first light housing enclosing a first LED,
a battery housing enclosing a battery, the battery configured to provide power to the first LED, and
a first actuator operable to toggle the first lighting assembly between a first plurality of operating modes;

a second lighting assembly coupled to the strap, the second lighting assembly including
a plurality of second LEDs, and
a second actuator operable to toggle the second lighting assembly between a second plurality of operating modes such that the second lighting assembly is operable independently of the first lighting assembly; and

a wire extending between the first lighting assembly and the second lighting assembly, the wire configured to provide power from the battery to the plurality of second LEDs,
wherein the second lighting assembly extends along more than 50% of a circumference of the strap, and
wherein the second lighting assembly follows a curvature of the strap.

2. The headlamp of claim 1 , wherein the wire includes coils to permit expansion and contraction of the wire.

3. The headlamp of claim 1 , wherein the strap is configured to be worn over a hard hat.

4. The headlamp of claim 1 , further comprising reflective material disposed about an outer periphery of the strap.

5. The headlamp of claim 4 , wherein the reflective material comprises reflective tape.

6. The headlamp of claim 1 , wherein the first LED and the plurality of second LEDs are configured to emit white light.

7. The headlamp of claim 1 , wherein the first plurality of operating modes includes a high intensity mode, a low intensity mode, and a flashing mode.

8. The headlamp of claim 1 , wherein the second plurality of modes includes a flashing mode.

9. The headlamp of claim 1 , wherein the first lighting assembly includes a spotlight reflector positioned in front of the first LED.

10. The headlamp of claim 1 , wherein each of the plurality of second LEDs includes a domed top.

11. The headlamp of claim 1 , wherein the first actuator includes a pushbutton.

12. The headlamp of claim 1 , wherein the second actuator includes a pushbutton.

13. The headlamp of claim 1 , wherein the first lighting assembly includes a battery cover pivotally coupled to the battery housing, and wherein the battery includes a single-use alkaline battery.

14. The headlamp of claim 1 , wherein the second lighting assembly is configured to distribute light at least partially around the circumference of the strap to increase visibility of a wearer of the headlamp from multiple directions.

15. A headlamp comprising:
a strap configured to be worn over a hard hat;
a bracket coupled to the strap;
a first lighting assembly pivotally coupled to the bracket, the first lighting assembly including
a first light housing enclosing a first LED,
a battery housing enclosing a battery, the battery configured to provide power to the first LED, and
a first actuator operable to toggle the first lighting assembly between a first plurality of operating modes including a high intensity mode, a low intensity mode, and a flashing mode;

a second lighting assembly coupled to the strap, the second lighting assembly including
a plurality of second LEDs, and
a second actuator operable to toggle the second lighting assembly between a second plurality of operating modes such that the second lighting assembly is operable independently of the first lighting assembly; and

a wire extending between the first lighting assembly and the second lighting assembly, the wire configured to provide power from the battery to the plurality of second LEDs, the wire including coils to permit expansion and contraction of the wire,
wherein the first LED and the plurality of second LEDs are configured to emit white light,
wherein the second lighting assembly extends along more than 50% of a circumference of the strap, and
wherein the second lighting assembly is configured to distribute light at least partially around the circumference of the strap to increase visibility of a wearer of the headlamp from multiple directions.

16. The headlamp of claim 15 , wherein the second lighting assembly is coupled to the strap by a plurality of couplers such that the second lighting assembly follows a curvature of the strap.

17. The headlamp of claim 16 , wherein the second plurality of modes includes a flashing mode.

18. The headlamp of claim 17 , wherein the first lighting assembly includes a spotlight reflector positioned in front of the first LED, wherein each of the plurality of second LEDs includes a domed top, wherein the first lighting assembly includes a battery cover pivotally coupled to the battery housing, and wherein the battery includes a single-use alkaline battery.

19. A headlamp comprising:
a strap configured to be worn over a hard hat;
a bracket coupled to the strap;
a first lighting assembly pivotally coupled to the bracket, the first lighting assembly including
a first light housing enclosing a first LED,
a battery housing enclosing a battery, the battery configured to provide power to the first LED, and
a first actuator operable to toggle the first lighting assembly between a first plurality of operating modes including a high intensity mode, a low intensity mode, and a flashing mode;

a second lighting assembly coupled to the strap by a plurality of couplers such that the second lighting assembly follows a curvature of the strap, the second lighting assembly including
a plurality of second LEDs, and
a second actuator operable to toggle the second lighting assembly between a second plurality of operating modes such that the second lighting assembly is operable independently of the first lighting assembly; and

a wire extending between the first lighting assembly and the second lighting assembly, the wire configured to provide power from the battery to the plurality of second LEDs, the wire including coils to permit expansion and contraction of the wire,
wherein the first LED and the plurality of second LEDs are configured to emit white light, and
wherein the second lighting assembly is configured to distribute light at least partially around the circumference of the strap to increase visibility of a wearer of the headlamp from multiple directions.

20. The headlamp of claim 19 , wherein the first lighting assembly includes a printed circuit board positioned between the first LED and the battery housing.
