Definitions

  • the invention relates to a recessed spotlight with a holder for mounting in a mounting surface, in particular a ceiling, and a bulb holder, which is rotatably mounted and / or pivotally mounted in a housing which is at least substantially dust-tight in the illumination direction by means of a translucent cover. Due to the pivotable mounting of the lamp holder and possibly a reflector coupled thereto, the emission angle of the recessed spotlight can be adjusted in a desired manner.
  • Such a recessed spotlight with adjustable beam angle is for example from the Fig. 3 and 4 the German patent application DE 10360947.4 known to the applicant.
  • this radiator it is possible to swivel out a reflector coupled to the light-emitting means holder in regions from the housing, wherein the reflector opening located in the illumination direction can be sealed in a dust-tight manner by means of a transparent pane.
  • the example in Fig. 4 is formed between housing and reflector, a gap which allows penetration of dust into the housing interior to a certain extent.
  • a recessed spotlight of the type mentioned in which independent of the respective adjusted beam angle or regardless of the respective pivot angle of the bulb socket a uniform appearance of the recessed spotlight is ensured, in particular, a seal of the housing interior against the ingress of dust can be achieved should.
  • the use of high-pressure halogen lamps in a recessed spotlight should preferably also be possible by ensuring protection against UV light and against falling fragments of a bursting lamp.
  • the translucent cover is coupled to the housing in such a way that its position always remains unchanged, irrespective of the respective given pivoting angle of the illuminant mount, so that the appearance of the recessed spotlight, which is substantially shaped by the position of the translucent cover, is pivoted by the illuminant mount can not be changed significantly.
  • the translucent cover can be formed in particular when using a high-pressure halogen lamp as a UV filter, in which case it also provides protection against falling fragments of a bursting high-pressure halogen lamp.
  • the translucent cover By fixed and fixed during operation of the recessed spot position of the translucent cover, the translucent cover can be coupled in a particularly effective dustproof with the housing, since a mechanically complex enabling a relative movement between the translucent cover and housing for setting different angles of radiation is not required. In this respect, it is possible to improve the dustproofness of a recessed spotlight, since it is not necessary to provide an additional pivoting mechanism acting on the illuminant mount or a reflector between the translucent cover and the housing.
  • An object of the present invention is to improve recessed spotlights of the type described in that a more comfortable operation of the same is possible.
  • this is achieved in that in the housing an actuatable from the outside of the housing forth pivoting mechanism for pivoting the light emitting device is present.
  • two provided for actuating the pivot mechanism externally accessible screws can be arranged in particular in the region of the translucent cover, each screw is responsible for pivoting the bulb socket or the reflector to one axis.
  • the luminous means holder or the reflector can be mounted via a gimbal joint whose two axes of articulation are in each case in operative connection with the adjusting screws via a flexible shaft.
  • the gimbal joint can be pivotally mounted in particular in Ausblendring.
  • the maximum possible pivoting angle about both joint axes of the gimbal joint can each be a maximum of +/- 45 ° and preferably approximately between +/- 30 ° and +/- 35 °.
  • a corresponding limitation of the swivel angle can be achieved by known from the prior art attacks, which are provided in the region of the joint axes.
  • the bulb holder is pivotable about two mutually perpendicular axes, since in this case virtually any tilt angle can be adjusted so as to create the respectively desired lighting situation can.
  • the light-emitting means can either be mounted alone or, which is preferred, together with a reflector, pivotably mounted in the housing. It is advantageous if the reflector and a preferably coupled with this filter disc are interchangeably stored in the housing, so adjusted in this way, for example, different lighting characteristics and beam angle and / or produces different light colors can be.
  • the use of UV and IR filters is also possible with provision of said filter disk.
  • the light-permeable cover provided according to the invention can also be designed as a UV and IR filter.
  • a flexible cable which in certain embodiments, for example in such as hereinafter in connection with the FIGS. 1 to 6 is described, may have a plug connection.
  • a connector it is then possible to solve a complete, housed in the housing emitter unit with lamp holder, reflector, light sources and possibly other parts of the housing, which allows, for example, a convenient replacement of lamp or reflector.
  • the diameter of the Ausblendrings can be dimensioned so that in each pivot position of the reflector, a distance between the reflector and Ausblendring is ensured. It is thus reliably avoided that at certain pivot positions of the reflector, a collision between the reflector and Ausblendring occurs.
  • the diameter becomes of Ausblendrings usually sized slightly larger than the diameter of the reflector located in the illumination direction reflector opening.
  • the height of the Ausblendrings can be dimensioned smaller than the reflector height and in particular can be less than 50% of the height of the reflector.
  • a particularly efficient effect of the Ausblendrings can be achieved if its inner side has a lower reflectivity than its outer side, the inside can in particular absorbent and the outside in particular reflective properties. Due to the low reflectivity or the absorbing properties of the inside of the Ausblendrings is effectively avoided that when viewing the recessed light according to the invention under an oblique viewing angle for the viewer a glare occurs.
  • the reflective properties of the outside of the masking ring can be used to direct a portion of the light generated by a luminous means into a region of the housing surrounding the reflector. This is particularly useful when a reflector opening located in the illumination direction defines a direct light exit area which is surrounded at least in regions by a diffuse light exit area.
  • the direct light exit region and the diffuse light exit region can be acted upon by a common light source.
  • the reflector opening defining the direct light exit region can be assigned to a direct light reflector, on whose side facing away from the direct light exit region an additional or background reflector is provided.
  • the direct light reflector then also has a rear opening through which light can pass to the additional or background reflector, which is formed, for example, by the inside of the housing of the recessed spotlight according to the invention and / or by the outside of the direct light reflector.
  • a sensible distribution of light between direct light exit region and diffuse light exit region can be achieved if one region of the luminous means is located within the direct light reflector and another region of the luminous means is between direct light reflector on the one hand and additional or background reflector or illuminant holder on the other.
  • Conventional lighting means consist for example of a clear glass bulb, in which the actual, light-generating element is arranged. It is advantageous if the light-generating element is located in the focal point of the direct light reflector and the glass bulb protrudes from the back of the direct light reflector, so that this part of the glass bulb between the direct light reflector on the one hand and additional or background reflector or light-emitting is on the other. Sufficient light then reaches the diffuse light exit area via this part of the glass bulb.
  • the translucent cover according to the invention which runs parallel to the installation plane, can be made transparent in the direct light exit region and can be formed as a diffuser in the diffuse light exit region.
  • the light-permeable cover in two parts, a first part being formed by a transparent pane which covers both the direct light exit area and the diffuse light exit area and closes the housing in a dust-tight manner, and the second part consists of a transparent pane placed on the transparent pane. consists of the direct light exit region surrounding lens.
  • the shape of the diffuser then corresponds to the shape of the diffuse light exit region.
  • the Ausblendring prevents direct irradiation of the diffuse light exit region by the lighting means, so as to ensure that only indirect and thus less intense light reaches the diffuse light exit region.
  • the light-permeable cover provided according to the invention can be made detachable or swing-away from the housing.
  • closure mechanisms can be used here, as described for example in the German patent applications DE 10360948.2 and DE 10 2004 048 484.8 are described by the applicant.
  • the diameter of the blanking ring connected to the translucent cover is dimensioned such that when the translucent cover is released or pivoted away, a distance between reflector and blanking ring is ensured, whereby a collision between reflector and blanking ring is reliably avoided.
  • the luminous means holder can also be pivotably mounted in a hinge bracket arrangement about an axis extending parallel to the translucent cover, wherein the hinge bracket arrangement itself can be rotatably mounted about an axis perpendicular to the translucent cover.
  • the maximum possible pivoting angle about the parallel to the translucent cover extending axis for example, a maximum of +/- 45 °, and preferably about +/- 35 °.
  • the maximum possible angle of rotation about the axis perpendicular to the translucent cover extending axis is preferably at least 180 °, so that in turn virtually any radiation angle can be adjusted.
  • suitable stops can be provided in each case for limiting the pivoting and rotational movements.
  • a spring element in particular a conical spring
  • the spring element inhibits the rotational movement of the joint bracket assembly in a desired manner, so that no unintentional adjustment of a once set pivot angle can occur.
  • the spring element which is designed in particular as a conical spring, at the same time allows minimized height a smooth running of the hinge bracket assembly about the axis perpendicular to the translucent cover extending axis, so that the respective desired rotation angle can be adjusted without, for example, jerky movements of the hinge bracket assembly result.
  • a simplified joint construction is possible only by using two flexible discs and said spring element. This structure will be described below with reference to the Figures 12 and 13 explained in more detail.

  • the housing can be closed in a dust-tight manner by means of a closure surface 16 fitted in the housing frame 10.
  • the closure surface 16 consists of a frame-shaped, substantially square or, for example, also circular element, in which a light-permeable cover 18 is held.
  • the translucent cover 18 consists of a complete frame element of the closure surface 16 filling transparent disc on which another disc is placed, which has a central circular recess and is simultaneously formed as a diffuser. This composition of the translucent cover 18 of two panes with different translucence results in that it is completely transparent in the region of the circular recess of the lens and light scattering in those areas in which the lens has no recess.
  • the connection between the translucent cover 18 and the frame member the closure surface 16 is designed such that when the closure surface 16 is closed (FIG. Fig. 1 ) no dust can penetrate into the housing 12.

  • the recessed light according to the Fig. 1 to 6 is thus closed dust-tight with the closure surface 16 closed by the translucent cover 18 in each pivot position of the reflector 40, so that no dust can penetrate into the interior of the housing. Furthermore, the respective desired pivot position of the reflector 40 and the associated lamp holder 46 can be adjusted via two externally accessible set screws 36 without the closure surface 16 is opened. Regardless of the respectively adjusted emission angle of the direct light over the transparent region of the transparent cover 18, it is ensured that in each pivoting position of the reflector 40, a small portion of the light generated by the illuminant 44 exits the recessed light via the light-scattering region of the transparent cover 18.
  • An inventive recessed spot according to Fig. 1 can be combined with other emitters of the same size, so that overall elongated light fields can be created, which are formed by a plurality of rows arranged radiators, which are preferably housed in a common housing.
