## Abstract

A portable, battery-operated flashlight having improved pivoting, switching and focusing features is disclosed. In one aspect of the invention, the flashlight takes the form of an attachment to a head gear for hands free use. In another aspect of the invention, the flashlight takes the form of a head lamp held in place on a user's head by an elastic band. The pivot connection between the body and the base, as well as the serrations on an exterior surface of the body, allows a user to adjust any angular direction of the light as desired. In another aspect of the invention, the flashlight takes the form of a long-handled flashlight having improved switching and focusing capabilities, such that axial movement of the switching assembly turns the flashlight “on” or “off,” as well as causing a position of the lamp to vary in order to focus or defocus the light.

## Claims

### Claim 1

A headlamp, comprising:
a body for retaining at least one battery, said body having a plurality of serrations;
a base attached to said body by at least one pivot connection point, said base having a stop;
a headgear attached to the base; and
a light source, housed within said body, and selectively electrically connected to said at least one battery to cause said light source to emanate light;
wherein said stop is capable of engaging with one or more of said serrations to facilitate desired angular adjustment of light emanating from said light source; and
wherein said pivot connection point is located substantially between said at least one battery and said light source.

### Claim 2

A headlamp, comprising:
a power supply;
a body having a plurality of serrations;
a base attached to said body by at least one pivot connection point, said base having a stop;
a headgear attached to the base; and
a light source, attached to said body, and selectively electrically connected to said power supply to cause said light source to emanate light;
wherein said stop is capable of engaging with one or more of said serrations to facilitate desired angular adjustment of light emanating from said light source; and
wherein said pivot connection point is located substantially between said power supply and said light source.

### Claim 3

A headlamp, comprising:
a light source;
a reflector;
a body for retaining at least one battery, said body having a plurality of serrations;
a base attached to said body by at least one pivot connection point, said base having a stop;
a headgear attached to the base; and
an assembly for housing said light source and said reflector within said body;
wherein said stop is capable of engaging with one or more of said serrations to facilitate desired angular adjustment of light emanating from said light source; and
wherein said pivot connection point is located substantially between said at least one battery and said assembly.

### Claim 4 (depends on 2)

The headlamp of claim 2, further comprising a head that is attached to the body and that contains the light source.

### Claim 5 (depends on 4)

The headlamp of claim 4, wherein the head is rotatable to selectively electrically connect the power supply to the light source.

### Claim 6 (depends on 4)

The headlamp of claim 4, wherein the head is rotatable to adjust the focus of the light emanating from the light source.

### Claim 7 (depends on 2)

The headlamp of claim 2, wherein the base is configured to engage a user's forehead.

### Claim 8 (depends on 7)

The headlamp of claim 7, wherein the base is arched.

### Claim 9 (depends on 2)

The headlamp of claim 2, wherein the power supply comprises at least one battery.

### Claim 10 (depends on 9)

The headlamp of claim 9, wherein the power supply comprises two batteries.

### Claim 11 (depends on 2)
