## Abstract

A battery operated illumination device having a pivoting head, with first and second independently controlled light sources. In a normal use orientation a spot light beam from a first light source is directed along a forward axis oriented at 90 degrees with a longitudinal axis of the device housing. A flood light beam from a second light source in the pivoting head is directed along an axis disposed between 30 and 60 degrees below the forward axis. In an alternate use orientation the pivoting head may be pivoted through up to 90° from the forward axis.

## Claims

### Claim 1

A portable, battery operated flashlight, comprising:
a body having a longitudinal axis and containing a battery power source and an ON-OFF control circuit wherein the body includes a hands-free support device for supporting the body on a user's clothing, body or belt; and
a single light source housing pivotably attached to an upper portion of the body and including first and second light sources oriented along respective first and second axes separated by a predetermined angle θ substantially within the range of 30° to 60°;
wherein the single light source housing is configured to pivot in a coplanar relationship with respect to the longitudinal axis of the body between a first position aligned with a reference axis oriented at a right angle to the longitudinal axis and a second position directed along the longitudinal axis;
wherein a plurality of detents secures the pivotable light source housing at the first and second positions and a third intermediate position therebetween.

### Claim 2 (depends on 1)

The flashlight of claim 1, wherein:
the body includes a lower portion configured for supporting the body on a horizontal surface.

### Claim 3 (depends on 1)

The flashlight of claim 1, wherein:
the hands-free support device is selected from the group consisting of a spring clamp, a spring clip, a lanyard, a clip for receiving a belt, a ring for receiving a hook device, and a keychain clip.

### Claim 4 (depends on 1)

The flashlight of claim 1, wherein the first and second light sources comprise:
independent light emitting diodes (LEDs); wherein one of the first and second light sources is configured to provide a spotlight beam; and
the other of the first and second light sources is configured to provide a flood light beam.

### Claim 5 (depends on 1)

The flashlight of claim 1, wherein:
the light source housing is configured to pivot between the first position along the reference axis and a 90° alignment thereto; and
the 90° alignment defines the second position directed upward from the 0° alignment.

### Claim 6 (depends on 5)

The flashlight of claim 5, wherein:
the body and the light source housing are configured with a plurality of detents disposed to secure the light source housing at the first and second positions and an intermediate third position therebetween.

### Claim 7 (depends on 5)

The flashlight of claim 5, wherein:
the body and the light source housing are configured with a friction mechanism to secure the light source housing at any angle between the first and second positions.

### Claim 8 (depends on 7)

The flashlight of claim 7, wherein the friction mechanism comprises:
a brake operable to exert a clamping tension upon a pivot axis between the light source housing and the body.

### Claim 9 (depends on 1)

The flashlight of claim 1, wherein the predetermined angle θ is approximately 45°.

### Claim 10 (depends on 1)

The flashlight of claim 1, wherein the battery power source comprises one or more batteries.

### Claim 11 (depends on 1)

The flashlight of claim 1, wherein the ON-OFF circuit comprises:
a first switch operative to control the first light source; and
a second switch operative to control the second light source.

### Claim 12 (depends on 11)

The flashlight of claim 11, wherein:
the first and second switches are combined into a single switch mechanism.
