Abstract: An assembly for providing illumination to a selected incident area includes a support; a first illumination device coupled to the support, the first illumination device including a first light emitting device and a first lens positioned for focusing light emitted by said first light emitting device; a second illumination device coupled to the support, the second illumination device including a second light emitting device and a second lens positioned for focusing light emitted by said second light emitting device; the first and second lenses projecting defocused images of the respective first and second light emitting devices to the selected incident area.

Abstract: Disclosed is an illumination device for projecting a substantially uniform light at a remote distance.

Abstract: An illuminating headlamp consisting of a headband and at least one optical device providing illumination at a known distance from said optical device attached to said headband. Each optical device consists of a housing having an open first end and an open second end. There is a light emitting device attached to a mounting which is attached to the second end causing said light emitting device to be orientated at a known angle to an axis of said housing. At least one optically transparent lens is incorporated into said first end, and a means for adjusting said optically transparent lens in order to cause a focal point of the lens to be positioned behind said light emitting device, wherein a zone of substantially uniform illumination is projected at said known distance.

Abstract: A filter assembly includes a mounting element for receiving and mounting on a forward portion of a headlight, and a central opening, and a frame rotatably coupled to the mounting element, the frame having an optical filter for selectively blocking wavelengths below a first limit from the optical path between the source and the output. The frame is rotatable between a closed position in which the filter substantially covers the central opening of the mounting element, and an open position in which the central opening of the mounting element is substantially open. Both the mounting element and the frame have a central axis through their respective openings, which axis is substantially the central axis of light being emitted from a headlight when the filter assembly is mounted on a headlight.

Abstract: An optical connector for connecting an optical cable having a cylindrical endpiece to a light source has a structure having an interior bore with a longitudinal axis, a port for receiving an illuminating beam and another port for receiving the cylindrical endpiece. A channel is defined along the periphery of the bore in the structure. A generally circular shaped spring member is positioned in the channel. The inner diameter of the circular shape is slightly smaller than the outer diameter of the cylindrical endpiece, which allows the establishment of a secure, yet releasable, connection between the cylindrical endpiece and the spring member. If the person wearing the headset connected to the optical cable moves too far, the optical cable is released from the housing.
