Definitions

  • the invention relates to a reflector lamp with a round reflector and a socket provided in the center region of the round reflector for an elongated lamp which is accommodated in the socket with a vertically extending axis.
  • Reflector lights of this type are known, both in the form of pendant lights and in the form of recessed lights.
  • the object of the invention is to provide an economically producible reflector luminaire with a round reflector which fulfills both the requirement for targeted illumination of an area located below the luminaire and the requirements for mild and extensive room illumination.
  • This object is essentially achieved in that the luminous flux emanating from the illuminant is divided by a reflector element, which encloses a predeterminable region of the free end of the elongated illuminant, into a bundled downward directed central luminous flux and into a radial luminous flux directed against the circular reflector.
  • a reflector member enclosing the end region of the one-sided, elongated illuminant and the special reflector characteristics of this member, it is possible to specifically divide the available light output and, for example, to direct about 50% of the luminous flux directly downwards via the reflector member, and thereby a particular one well lit. To create the area, while the rest of the light, supported by the reflector organ, reaches the large circular reflector and is emitted from there in the form of a mild light to illuminate a larger area.
  • the reflector member is preferably rotationally symmetrical and in each case starting from an area of minimal diameter, i.e. starting from a constriction area with a downwardly widening main section and an upwardly widening secondary section, the axial extent of which is a fraction of the axial extent of the main section.
  • the axial extent of the upwardly widening sub-section can be, for example, about one fifth of the axial extent of the main section, the opening widths of the main section and sub-section of the reflector member preferably being essentially the same.
  • the reflector member is advantageously held in a glass body which receives the illuminant and which can be screwed to a mounting base enclosing the socket, i.e. by attaching the glass body, the reflector member is simultaneously positioned in the correct position with respect to the illuminant.
  • fade-out rings On the outside of the glass body, in the socket-side area, there are several fade-out rings, preferably inclined to the luminaire axis, which on the one hand ensure that the illuminant is shielded from direct view and on the other hand can help to direct light coming from the illuminant to the round reflector.
  • the lower edge of the round reflector is preferred in the Not arranged by the reflector member enclosed radiation area of the illuminant, so that it is also ensured that the total luminous flux emitted by the illuminant is used in a targeted manner and in part is emitted directly downwards via the reflector member or is guided to the round reflector and thus the targeted and defined radiation behavior is achieved.
  • the reflector lamp according to the invention can be designed both as a pendant lamp and as a recessed lamp.
  • a particularly simple and safe installation is made possible, only the easily accessible clamping screws are to be actuated and it can thus also be ensured that the installation can take place without contamination or damage to the sensitive reflector surface.
  • FIG. 1 shows a reflector lamp with a round reflector 1, in the center area of which a socket 2 for an elongated lamp 3, in particular for energy-saving lamps with a base on one side, is arranged.
  • the socket 2 is arranged within a chamber-like mounting base 9, from the lower end of which the circular reflector 2 extends outwards.
  • This chamber-like mounting base 9 is provided with an internal thread into which a glass body 8 closed at the end can be screwed in to enclose the illuminant 3.
  • a reflector member 4 is held in a bottom-side depression 10, which extends over a predeterminable part of the free length of the illuminant 3, for example about half the free length of this illuminant 3.
  • the reflector member 4 is rotationally symmetrical and comprises, starting from a region 7 of minimal diameter, a main section 5 widening downwards and an auxiliary section 6 widening upward. Both sections widen at least substantially to the same diameter, the main section 5 being convex and the secondary section 6 is concavely curved.
  • the glass body 8 also has a socket-side one cylindrical area and an area widening towards the free end, with several blanking rings 11 being provided in the cylindrical area on the outside of the glass body, which are arranged inclined and - viewed from the socket side - enclose an acute angle with the axis of the reflector lamp.
  • the lower edge of the round reflector 1 is significantly lower than the socket 2 and is preferably located in the region of the part of the illuminant 3 that is not enclosed by the reflector element 4.
  • the fade-out rings 11 have the additional advantage and can also be specially designed so that a predeterminable proportion of the luminous flux in the built-in version of the lamp is directed beyond the reflector area directly against the wall or ceiling into which the built-in lamp is integrated, so that a desired ceiling or wall illumination.
  • the circular reflector 1 is formed in two parts in the exemplary embodiment according to FIG. 1 and is composed of a central reflector 13 connected to the mounting base 9 and a reflector ring 14 which is connected to the central reflector 12 via spacers 15, so that also between the central reflector 13 and the reflector ring 14 Light can leak.
  • a box part 18 is formed in connection with the mounting base 9, in which there is a receiving space 16 for an electronics unit 19 and via which the pendulum 17 is also fastened.
  • the desired proportion of light which can be about 50%, for example, is directed centrally downwards, while the remaining proportion of light follows on from the light coming directly from the illuminant 3 to the round reflector 1 and from the secondary section 6 of the reflector element 4 above the round reflector 1 directed light portion over the round reflector a larger area illumination of the room is obtained with mild light.
  • the desired light distribution can be influenced by suitable design and positioning of the reflector member 4.
  • the glass body 8 is preferably designed as a glass or plastic body closed at the end, an arrangement which is open at the end can in principle also be used.
  • FIG. 2 shows a built-in version of the circular reflector lamp according to FIG. 1, parts which correspond to one another are provided with the same reference symbols.
  • the round reflector 1 is formed in one piece and is provided with an outer edge area which can be clamped in a ceiling or wall in order to fix the lamp to the edge area of a recess.
  • the built-in version of the round reflector lamp is equipped with a special clamping and clamping system.
  • clamping screws 20 Adjacent to the socket 2, two diametrically opposed clamping screws 20 are provided, which are rotatably supported and on each of which a clamping slide 21 can be moved vertically by rotating these clamping screws 20.
  • a flexible tension member 22 is connected to each of these tensioning slides 21, the two free ends of which are each articulated on a rocker arm 23, which can be seen in the partial sectional view according to FIG. 3.
  • Each of the four rocker arms evenly distributed over the circumference 23 is connected via a deflection roller 24 to the tension member 22, so that when the tensioning screws 22 are actuated and the associated tensioning slide 21 is moved downward, tensioning of the tension members 22 takes place and thereby the rocker arms against the edge of the wall adjacent to the respective wall cutout 26 are pressed so that the desired jamming of the reflector edge on the outside of the wall and thus the corresponding mounting of the recessed light.
  • the rocker arms 23 are pivoted upward by appropriate elastic bands 25 so that they are located within the outer peripheral contour of the lamp and do not impede the insertion of the lamp into the respective recess. It is of major advantage in connection with this type of mounting that it enables problem-free and quick mounting of the recessed luminaire from the socket side and that the sensitive reflector surface does not have to be touched during assembly and therefore there is also no risk of damage or contamination.
