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: An apparatus comprising a human vision solid state display filter material with a first and a second surface with a semitransparent material between. The first surface, the second surface, the semitransparent material or combinations thereof have a spectral pass-band and an off-band, the pass-band comprising at least three spectrally discrete bands that overlap with emission peaks from a solid state display and the off-band rejecting a portion of the human visible spectrum. Wherein a transmitted ratio of the pass-band to the off-band increases human visual perception of the solid state display when viewed under ambient light conditions.
