Definitions

  • Such lighting devices with framing exist and are generally produced as illustrated diagrammatically and in longitudinal section in FIG. 1. They include inside a housing 1 a light source, formed by an incandescent lamp 2, generally a normal halogen lamp, and a smooth or faceted reflector 3, a condenser formed by two lenses 4,5, a diaphragm 6 and a sliding focusing lens 7.
  • a light source formed by an incandescent lamp 2, generally a normal halogen lamp, and a smooth or faceted reflector 3, a condenser formed by two lenses 4,5, a diaphragm 6 and a sliding focusing lens 7.
  • the present invention aims to provide a lighting device with framing which is compact, inexpensive, with better light output and free from the aforementioned drawbacks.
  • This object is achieved by the device according to the invention, which is characterized by the fact that it comprises a housing containing a light source, a diaphragm directly delimiting a portion of the light beam emitted by the source and a sliding lens for focusing. point.
  • the illustrated framing lighting device comprises a housing 8 containing a light source 9 formed by a reflector 10 and a halogen bulb 11 with axial longitudinal filament L.
  • the internal surface of the reflector 10 is granited, bumpy or hammered and creates a diffuse beam. Having a light source with an axial filament avoids the phenomenon of central shadow.
  • This case includes one or more slides or guides 12 allowing the insertion of a diaphragm formed by one or more tabs.
  • FIG. 5 illustrates three variants of the diaphragm, each consisting of a single tongue 13A, 13B and 13C, each having an opening of circular, for example 14A or triangular 14B shape, respectively several openings 14C corresponding to letters intended to be projected.
  • the diaphragm illustrated in FIG. 6 it is formed by several tongues 13 (here four) with rectilinear end, arranged in the same plane and which define between them, once inserted in the corresponding guides 12 of the housing 8, a polygonal opening 14 (here square).
  • the shape and dimensions of this opening 14 can be modified by moving by sliding radial (arrow I) one or more of the tongues 13; in addition, a clearance can be provided between the guides 12 and the tongues 13 so that the latter can also be slightly angularly displaced (arrow II), in order to correct any centering defects of the light source. , or to frame an object at non-right angles.
  • the diaphragm is placed in close proximity to the light source and that no optical element is inserted between these two elements.
  • the diaphragm therefore directly limits the light beam emitted by the source 9,10,11.
  • the front part of the housing 8 is provided with a sliding lens 15 provided with a lens 16, which is used for focusing.
