Abstract: A tape light carrier system includes an elongate structure having a tape light receiving recess along its length. An inner and outer set of slots are arranged on inner sides of the tape light receiving recess. An inner covering lens is engaged with the inner set of slots and an outer covering lens is engaged with the outer set of slots. A flexible linear light source is affixed to the bottom of the tape light receiving recess using an adhesive. The inner covering lens is arranged in an arc and holds the flexible linear light source in position along the bottom of the tape light receiving recess. A T-slot may be arranged along the underside of the elongate structure, and barn door type shutters may be arranged along the sides of the tape light carrier.

Abstract: A system for detecting patterns on objects having reflective or high visibility colored material thereon. The system includes a lighting unit that includes a main housing having a front opening and a cavity, a first visual lighting assembly positioned within the cavity of the main housing that emits light in the visible spectrum, and a second ultraviolet lighting assembly positioned a fixed distance from the first visual lighting assembly within the cavity of the main housing that emits light in the ultraviolet spectrum, a camera having a field of view within which the system is configured to detect patterns of reflective or high visibility colored material on one or more objects, a warning device to alert the operator when a marked object enters the camera's field of view. A controller/processor is programmed to detect when a pattern of reflective or high visibility colored material enters the camera's field of view.

Abstract: A lighting unit for use in low lighting environments such as underground mines is provided. The lighting unit includes a main housing having a front opening and a cavity, a first visual lighting assembly positioned within the cavity of the main housing that emits light in the visible spectrum, and a second ultraviolet lighting assembly positioned a fixed distance from the first visual lighting assembly within the cavity of the main housing that emits light in the ultraviolet spectrum. The lighting unit is part of a system for detecting patterns on objects having reflective or high visibility colored material thereon. In addition to the lighting unit, the system includes a camera having a field of view within which the system is configured to detect patterns of reflective or high visibility colored material on one or more objects, a warning device to alert the operator when a marked object enters the camera's field of view.

Abstract: A gobo with a substrate having at least one peripheral edge a body extending from the peripheral edge, the body having two faces and a structural network on at least one of the two faces, the structural network generally extending to the peripheral edge. An optical pattern is disposed on or through the body, with the structural network extending on the body only to an edge of the optical pattern. The structural network is integral with the substrate.

Abstract: A lighting device including an ultraviolet light source emanating ultraviolet light, a visual light source and a light directing device. The visual light source is coupled to the ultraviolet light source, and the visual light source emanates visual light. The light directing device is arranged to direct the visual light in a first direction primarily within an angle of illumination. The light directing device is further arranged to direct the ultraviolet light in an area wider than the angle of illumination.

Abstract: A strobe light system for use with a camera, the strobe light system including an LED light source, a triggering signal input for the reception of a triggering signal, an electrical power source and a control circuit. The control circuit is coupled to the LED light source. The control circuit has a first transistor and a second transistor. The first transistor, the second transistor and the LED are electrically in series with the electrical power source. The first transistor is controlled to establish an electrical power level that is to be conducted through the LED. The second transistor being subject to the triggering signal to thereby electrically conduct for a predetermined amount of time thereby establishing an electrical current pulse through the LED.
