Abstract
559,603. Luminescent devices. LANDAU, B. Oct. 14, 1942, No. 14411. [Class 39 (i)] A device for aiding reading or writing in the dark comprises a flat support associated with a layer of luminous material which illuminates. from below, a sheet of paper placed upon said support. The support may have a smooth surface and a flat transparent or translucent sheet may cover the surface of the support on which the luminescent material is deposited. Alternatively the luminescent material may be deposited on the bottom of the transparent cover sheet. This sheet may be hingedly connected to a rigid support which also has a writing pad hinged thereto so that the luminous sheet can be interleaved with the pad. The rigid support may also have straps to attach it to the person of the user. A coat of pale varnish may be applied over the luminous material to protect it. The luminous material may be applied discontinuously for instance in strips 2 mm. in width spaced 2 mm. apart.
