This invention relates generally to a light panel light source shade in the form of a masking tape or sheet. Ideally the masks may be printed directly on a surface design layer for use with the light panel. The invention is for use in the field of decorative 5 lighting. The problem of the alternating bright and dark areas on an illuminated face of a pane of a light panel is that they produce an unpleasant mottled surface brightness around the perimeter or across a face of the pane of a light panel. A light pane light source shade is developed to produce a uniform intensity of light across the face of the light panel.
