1. A headlamp comprising:
- a base having a first surface adapted to bear against a user'"'"'s forehead and defining a first plane and a first normal line to the first plane;
a front face inclined downward relative to said first surface by a first angle;
a light assembly including;
a bezel having a rear surface rotatably supported relative to the front face of the base and a front surface inclined relative to said rear surface by a second angle;
a battery case attached to said bezel and defining a closed volume between the battery case and the bezel;
a battery located within said volume;
a generally circular reflector disposed at least in part within said volume;
a plurality of light emitters received in said reflector, said emitters adapted when energized to project a beam of light through the front surface of the bezel with the reflector internally reflecting light from the light sources to create a more uniform illumination field; and
a switch connected between said battery and said light emitter;
whereby rotation of the bezel relative to said base rotates the beam of light from a direction parallel to the normal line to a downward direction inclined relative to the normal line by the first angle plus the second angle.

Abstract
A headlamp includes a base having a front face defining a first imaginary plane along the front face and a first imaginary line orthogonal to the first plane. A light assembly is rotatably secured about the front face to the base. The light assembly includes a bezel having a rear surface defining a second imaginary plane along the rear surface and a second imaginary line orthogonal to the second plane so that the intersection of the first line and the second line defines a rotation angle that varies with the rotation of the light assembly relative to the base, thereby changing the attitude of the headlamp light assembly.
