Definitions

  • SHEET 20F 2 Ill l lw C) k J z I NVIZN 'IOILJ The invention relates to an arrangement for the illumination of objects such as books, placed underneath or on shelves.
  • the illumination of objects placed on shelves is generally provided by light sources mounted apart from and normally above the shelves.
  • the light intensity tends to be strongest on the upper shelves and weakest on the lower shelves, thus impeding perception of the objects displayed, in particular the reading of titles of the backs of the books.
  • the permanent siting of the light sources apart from the shelves and normally in the ceiling impedes repositioning of the shelves, as the intensity and direction of the light would thereby be altered, resulting in shaded areas and reduced light on the displayed objects.
  • the demand for flexibility is an absolute necessity.
  • location of the light sources apart from and usually at a certain distance above the shelves necessitates a fairly high light intensity in order to render, for example, book titles legible on the lower shelves.
  • the light source is sited along the rear edge of the shelf and thus built into it so that the hollow shelf surrounds and shields the light source, as set forth below.
  • the shelf is constructed in the form of a hollow cassette or consists of two parallel sheets of which the upper one is both supporting and shading in function and the lower one mainly solely shading in function.
  • the reflector is positioned along the front edge of the hollow shelf with its longitudinal axis parallel to the front edge and so arranged that it reflects the light issuing from the light source and passing through the hollow shelf arrangement downwards and upwards respectively onto the objects placed beneath or on the shelf.
  • the light source By placing the light source in the middle of a two-sided bookcase or cabinet so that it functions as a common light source for two opposite shelves positioned at the same height,
  • the maximum amount of light will reach the reflector and be reflected.
  • FIGS. 1 and 2 An illustrative embodiment of the invention is shown in FIGS. 1 and 2, the FIG. 2 being an in-part enlarged and more detailed view taken from FIG. 1. Each of FIGS. I and 2 are more fully described below.
  • FIG. 1 is a vertical sectional view of a two-sided shelf arrangement according to the invention with a total number of six shelves of each side.
  • Light source 1 is positioned in the middle between hollow shelves 2, along the front edge of which reflector 3 is positioned.
  • the ballasts 4 which the use of fluorescent light sources necessitates are installed in one of the structural members which comprise the structural frame supporting the shelves.
  • FIG. 2 is a vertical sectional view according to the invention and shows in part a detail of the arrangement shown in FIG. 1.
  • light source 1 is positioned in the middle between hollow shelves 2 along the front edge of which reflector 3 is positioned.
  • Light source 1 is a fluorescent lamp mounted between two detachable cover plates which allow a flow of air to pass the fluorescent lamp on both sides thus cooling it, and permitting easy change of the lamp.
  • the lower part of shelf 2 has been bent so as to allow a book support to be mounted there.
  • the form of the invention shown comprises a two-sided case or cabinet. There is nothing in the invention that prevents the construction of one-sided cabinets or two-sided cabinets with the opposing shelves positioned at different heights. in these events, each shelf reqUires its own separate light source.
  • An arrangement for the illumination of objects placed on a shelf consisting of the combination of a shelf and a light source, located along the rear edge of the shelf, said shelf being a hollow structure and substantially surrounds and shades the light source, the shelf consisting essentially of two parallel sheets of which the upper one is mainly both supporting and shading in function and the lower one is mainly solely shading in function, and said shelf being provided with a reflector positioned along the front edge of the hollow twosheeted shelf with its longitudinal axis parallel to the front edge and so arranged that the reflector reflects the light issuing from the light source and passing through the hollow shelf arrangement downwards and upwards respectively onto said objects.
