Abstract
An illumination device for mounting on the head of a user including a frame having a cross member and a pair of rearwardly extending temple members attached to opposite ends of the cross member. At least one focusable light assembly is rotatably mounted to the frame and includes a light source for emitting light. The light assembly is adjustable by the user for varying the vergence and direction of the light emitted from the light source.

An illumination device for mounting on the head of a user, said device comprising:
- a frame having a cross member and a pair of rearwardly extending temple members attached to opposite ends of said cross member;
- and
- a focusable light assembly mounted on each end of said cross member by a pivotable connection, each focusable light assembly including a base member with a light source for emitting light and a first lens, and a focusing sleeve movably engaged with the base member and having a second lens mounted therein, said focusing sleeve being axially displaceable with respect to said base member by the user to vary the distance between said first lens and said second lens to at least one of converge and diverge the light emitted from said light source, each focusable light assembly being aimable by movement on the pivotable connection such that both light assemblies illuminate a selected area in a user's view field.
An illumination device for mounting on the head of a user, said device comprising:
- a frame having a cross member and a pair of rearwardly extending temple members attached to opposite ends of said cross member;
- two focusable light assemblies rotatably mounted to said frame on opposite ends of said cross member, each of said focusable light assemblies including a base member mounted to said frame by a ball and socket joint, each base member having a cavity and a first lens mounted in said cavity, a light source disposed within said cavity of said base member for emitting light, and a focusing sleeve movably engaged with said base member and having a second lens mounted therein, said focusing sleeve being axially displaceable with respect to said base member by the user to vary the distance between said first lens and said second lens to at least one of converge and diverge the light emitted from said light source;
- and
- an electrical connector attached to said frame, said electrical connector being in electrical communication with said light sources and being adapted to be in electrical communication with a power source.
