Definitions

  • the invention relates to a ceiling device intended for lighting wards in hospitals, clinics and similar places.
  • the device according to the invention does away with these drawbacks and makes it possible, starting from the provision of a lighting unit, to effect a homo geneous, multi-directional area of light illuminating the whole of the surface, in spite of screens that may be interposed, so as to do away with casting of shadows and thereby assisting clinical examinations, care,observation of sores and the invalids complexion, without change in colour, while enabling the patient to read in any position, even away from the background wall, and without the neighbours being able to perceive directly the sources of light.
  • FIGS. 1, 2 the lighting unit in cross-section and elevation
  • FIGS. 3 and 4 the whole of the ceiling unit in longitudinal sectionand elevation
  • FIGS. 5 and 6 one of the applications of the device.
  • the ceiling fitting (FIGS. 1, 2,3, 4) consists of a central casing l in which are mounted two jointed slewable incandescent or spot lights, 2, 3 and provided with directional reflectors 4, 5 and 6, 7.
  • the shade 6 is vertical and the shade 7 slightly oblique to the light path from shade 6 at an angle of about 60.
  • Ventilating hoods l6, l7, 18 are provided on the lateral surfaces and on the longitudinal surfaces 19. There are then obtained direct beams of light A B as shown by arrows in FIG. 3 and the indirect projections C D, as shown by the arrows in FIG. 1, which ensure a luminous environment by reflection on the ceiling.
  • the lighting unit For medical attention, dressings, and examinations, the lighting unit provides with the maximum of clarity the lighting of the portion to be treated. It is also possible to condition the lighting to create a determined environment, enabling the patient to be seen as he is.
  • An overhead lighting fixture comprising, in combination,
  • a housing provided with a first pair of laterally spaced elongated casings and a second central elongated casing
  • each tube to provide for directing the light therefrom at an angle to the ceiling, the directed light having vertical and oppositely directed lateral components away from the first pair of respective casings,
  • An overhead lighting fixture according to claim 1 wherein said spotlight lamps are provided with reflectors and shades for directing the light from the incandescent lamps in said respective directions, the light transmission paths of said incandescent lamps being at an angle of 60 to each other.
