    Abstract: A method of irradiating a work piece may include forming a cutout recessed from a surface of a light guide, positioning the work piece inside the cutout, irradiating a light input surface of the light guide with UV light, and guiding the UV light from within the light guide through recessed surfaces of the cutout to irradiate the work piece. In this way more uniform irradiation of all curable surfaces of a work piece may be achieved, the energy and time consumed during irradiation of the work piece may be reduced thereby lowering operating costs, and the radiation delivery system may be made more compactly, thereby making it more convenient and practical for daily applications.

    Abstract: Systems and methods for achieving increased irradiation and/or illumination in a photo reactive system is disclosed. In one example, a photo reactive system includes a light source, a refractive cylindrical optic, and a curved reflector. By utilizing the refractive cylindrical optic, angular spread of the light source is reduced, which in turn reduces a size of the curved reflector for directing the light rays onto a work piece. Consequently, a more compact photo reactive system with higher irradiation and/or illumination capabilities can be achieved.

    Abstract: A method may comprise: supplying light energy from a light emitting device principally along a first axis; sensing the light energy with a light sensing device oriented along a second axis, wherein the second axis is oriented substantially orthogonally to the first axis; and adjusting the light energy in response to the sensed light energy. In this way, an amount of retro-reflected light incident at the light sensing device may be reduced, measurement error of the light sensing device may be reduced, and control precision and reliability of the lighting system for curing a work piece can be increased.

    Abstract: A radiation monitor for a lighting device, and operating methods and systems therefor are provided. In one example, a radiation monitor may include a first sensor receiving radiation output directly from a light-emitting element of the lighting device and radiation output from external sources; and a second sensor receiving the radiation output from the external sources without receiving the radiation output directly from the light-emitting element of the lighting device. The radiation monitor may determine an intensity of the radiation output directly from the light-emitting element based on a difference in the output signals from the first sensor and the second sensor.
