Abstract

A lighting device includes a housing, multiple light emitting diodes (LEDS), and multiple magnifier lenses. The multiple LEDS and the multiple magnifier lenses are located in the housing. Each of the magnifier lenses corresponds to a different one of the LEDS, and there are less magnifier lenses than LEDS. Each LED that has a corresponding magnifier lens is arranged with respect to its magnifier lens so that substantially all of the light emitted by the LED only traverses its corresponding magnifier lens. At least one of the LEDS emits light that does not traverse any of the multiple magnifier lenses.

Claims

1. A lighting device, comprising:

a rear housing defining a battery compartment;

a front housing comprising;

a plurality of light emitting diodes;

a plurality of lenses, wherein there are less lenses than light emitting diodes;

a support member that supports the plurality of lenses relative to the plurality of light emitting diodes, each of the lenses corresponds to a different one of the plurality of light emitting diodes;

each lens is arranged with respect to a light path of a corresponding light emitting diode; and

a light path of at least one of the light emitting diodes does not substantially traverse the plurality of lenses;

a hinge assembly that couples the rear housing to the front housing; and

a strap coupled to the rear housing.

2. The lighting device of claim 1, the hinge assembly is rotatable about a horizontal axis to allow the front housing to rotate relative to the rear housing in order to adjust the height positioning for the light paths of the light emitting diodes.

3. The lighting device of claim 1, the plurality of lenses are tilting magnifier lenses focused onto a single target area.

4. The lighting device of claim 1, further comprising a three position switch, a first position operative to control the at least one of the light emitting diodes having a light path that does not substantially traverse the plurality of lenses.
