  • the local proximity of the luminaire and the user and the possibility of positioning the luminaire with regard to a desk always present certain difficulties.
  • the light image of such a floor lamp can not be optimized for a specific relative position to the desk, since the arrangement of luminaire and workplace is always different.
  • the luminaire should be configured such that glare of the user is avoided and at the same time the workplace is illuminated according to the respective standards.
  • a luminaire with a lamp head is known in which first and second light means for a light output to the bottom are out.
  • the emission direction of the second light means is adjustable.
  • an LED luminaire with a luminaire head in which first LEDs and a second LED for a downwardly directed light output are arranged.
  • the light of the first LEDs is emitted through a lens through down.
  • the second LED is pivotally mounted so that the light emission direction can be changed.
  • Object of the present invention is therefore to provide a lamp that allows effective illumination of a workplace.
  • a luminaire in particular a floor or table luminaire, with a luminaire column still extending upwards from a luminaire base, on which a luminaire head is arranged, wherein the lamp head has first light means, the light of which is given off flat over a light emitting surface of the lamp head towards the bottom, in which, furthermore, the luminaire head has second light means, the light of which is emitted bundled to the bottom, the light emission direction of the second light means being variable.
  • the first light means is preferably associated with a light influencing element for glare-free illumination of the surface light.
  • a light influencing element which has a prism structure, in particular a microprism structure, or acts in a light-scattering manner.
  • the second lighting means comprise at least one pivotable radiator.
  • This radiator is preferably an LED radiator.
  • the second light means are preferably arranged laterally next to the light emission surface for the first light means, the second light means being arranged on two opposite sides of the light emission surface for the first light means.
  • the underside of the lamp head is completely closed by a light exit disk.
  • This light exit plate also preferably has a printing which has light-transmitting regions corresponding to the light emission surfaces for the first and second light means.
  • the second lighting means are preferably adjustable from the upper side of the lamp head.
  • the luminaire has means for emitting light towards the top and further a part of the light of the first light means is emitted towards the top.
  • the luminaire has third light means, to which a reflector arrangement is assigned, via which light is radiated exclusively towards the upper side. The light emitted upwards serves as indirect lighting and illuminates the entire room.
  • the present invention is a luminaire 1, which in Fig. 1 is shown. This is preferably a floor or table lamp 1.
  • the luminaire according to the invention has a lamp base 2 as well as a light column 3 still extending upwards from the lamp base. At the upper end of the light column 3 is also a lamp head 4th
  • Fig. 1 to 6 shown embodiment shows a lamp head 4, which has three different light means, which are discussed below. In Fig. 1 However, these lights are not recognizable.
  • the Fig. 1 are not visible, emit light over a light emitting surface 5 of the lamp head 4 flat to the bottom from. Further, the light from second light means emerges from the circular zones 12 of the lower surface. Furthermore, light is emitted upward by third light means as indirect illumination.
  • Fig. 2 further shows a schematic representation of the lamp head 4 according to the invention from the top side.
  • the reference numeral 6 denotes the first light means.
  • the first light means 6 are a compact fluorescent lamp.
  • other types of lighting are conceivable, for example, light-emitting diodes could be used as the first lighting means. In this case, it would also be conceivable for the light-emitting diodes to introduce light laterally into a light guide, via the underside of which light can then be emitted over a large area.
  • the light generated by the first light means is emitted via the light emitting surface 5 to the underside of the lamp head 4.
  • a preferably planar light influencing element 7 On the underside of the lamp head 4 is a preferably planar light influencing element 7.
  • the light influencing element 7 is a light exit disk 18 which completely closes off the underside of the lamp head 4.
  • the light-influencing element 7 is printed with a coating which is divided into different zones.
  • the printing forms a large translucent areas, which is preferably arranged centrally on the underside of the lamp head 4 and represents the light emitting surface 5 for the light of the first light means 6.
  • the light-influencing element 7 also serves to glare the light of the first light means 6.
  • the light-influencing element 7 has a prism structure, in particular a micro-prism structure.
  • the light-influencing element 7 may also be a diffusely scattering disk.
  • the lamp head 4 according to the invention has second light means 11, whose light is emitted bundled to the bottom, wherein the light emission direction of the second light means 11 is variable.
  • the exemplary embodiments illustrated here are adjustable light-emitting diode radiators 11 Fig. 2 two radiators 11 are shown, each on one side of the in Fig. 2 not shown light emitting surface 5 are arranged.
  • the printing of the underside of the lamp head 4 has in front of the LED emitters 11 on a translucent, preferably circular zone 12. These zones are for example in Fig. 1 to see. Alternatively, it is of course also possible to equip the lamp head 4 only with an LED emitter 11 or with two juxtaposed LED emitters 11 on one side of the light emitting surface 5. It is also possible to use other light sources for directional light emission.
  • the underside of the lamp head 4 is flat and almost frameless. Accordingly, a device 13 for changing the emission direction of the second light means 11 is not attached to the bottom, but at the top 9 of the lamp 1.
  • a handle 14 protrudes, with which the device 13 can be operated.
  • the lamp head 4 further comprises third light means 15, which is associated with a reflector assembly 16, is emitted via the light exclusively to the top 9 back.
  • the light emitted to the upper side 9 of the luminaire will usually illuminate a ceiling as indirect lighting and in this way illuminate the entire room.
  • the third lighting means 15 are two compact fluorescent lamps 15, which are arranged parallel to the compact fluorescent lamp 6, which is used as the first lighting means.
  • these third lighting means 15 are only optional. Through them, the lighting of a room can be optimized because they represent an ideal complement to the light of the first two light means 6, 11. However, the inventive combination of large-area light emitted medium brightness with bundled light for particularly good illumination of a limited area already by the first and second light means 6, 11 can be achieved.
  • Fig. 3 further shows a cross section through the in Fig. 2 illustrated lamp head 4 along the line III-III '.
  • a reflector 8 is arranged next to the first light means 6. This reflector 8 reflects the light emitted by the first light means 6 at very shallow angles in the direction of the light emission surface 5.
  • the upper side 9 of the light head 4 has an opening 10 for emitting light. Through this opening 10, a portion of the light of the first light means 6 is emitted to the top 9 back to lighten the ceiling area located above the lamp.
  • the lamp head 4 is constructed such that the majority of the light generated by the first light means 6 is emitted downwards. In this case, the light generated by the third indirect light illuminating means 15 is amplified by the light emitted upward from the first light means 6.
  • Fig. 4 shows a cross section through the in Fig. 2 illustrated lamp head 4 along the line IV-IV '.
  • the device 13 is seen, with which the orientation of the LED emitter 11 can be changed manually by a user.
  • a user can move the attached to the top of the light head 4 handle 14 to the side. This movement of the handle 14 is converted by the device 13 into a corresponding movement of the LED radiator 11.
  • Fig. 5 shows the lamp head 4 according to the invention with attached light influencing element 7. This is provided with a print which has the light emitting surfaces for the first and second light means 6, 11 corresponding translucent areas. The light of the first light means 6 is radiated through the light emitting surface 5, and the light of the second light means 11 exits from the circular openings 12.
  • the luminaire 1 according to the invention is particularly suitable for illuminating office workstations.
  • the first light means 6 produce a fairly large and uniform illumination with a medium intensity. Since the light of these first light means 6 is blinding, the glare of a user and reflections on upright screens are avoided.
  • the changeable in their emission direction second light means 11 also emit focused light.
  • the second light means 11 can now be aligned such that a comparatively small working zone is illuminated and illuminated particularly efficiently.
  • the floor lamp 1 shown in the figures with two LED spotlights 11 is particularly suitable for use at a double workstation.
  • an LED spotlight 11 is provided in this case, which can be pivoted by the respective user so that it illuminates the user's workplace in an ideal manner. If, however, the luminaire 1 according to the invention is used to illuminate a single workstation, then it is sufficient for the luminaire head 4 to have an LED spotlight 11.
  • the combination of large-area emitted light of the first light means 6 with the bundled radiated light of the second light means 11 ensures that on the one hand, the entire office is lit and at the same time the important work area is particularly well lit. Since the light emission direction of the LED radiator 11 is also variable, results in a flexibility with respect to the installation of the lamp.
  • the third, light sources 15 jobs can be illuminated in a particularly effective manner, the light intensity to the center of the workplace increases and ultimately the crucial area using the spotlight 11 are selectively illuminated can.
  • Fig. 6 shows the light image generated by the luminaire 1 according to the invention in a schematic representation.
  • the lamp 1 is used to illuminate a desk 5, which provides two workstations, as well as its surroundings.
  • the lamp 1 has two LED spotlights 11. These LED emitters 11 have each been aligned such that their light illuminates one of the two workplaces.
  • the reference numeral 19 indicates the illuminated by the LED emitters 11 Area on. In this area 19, the maximum brightness is achieved, since here the light of all three light means is summed up.
  • the area 19 typically corresponds to the field of vision of a user sitting at an end face of the desk 5. Since LED emitters 11 are changeable in their emission direction, they can be aligned exactly to the work area.
  • the area 21 is illuminated by the large area radiating first light means 6.
  • the first light means 6 thus illuminate an approximately circular region 21, in the center of which the light 1 stands.
  • the area 21 includes the desk 19 and its immediate surroundings.
  • Reference numeral 22 also indicates the area illuminated by the third light means 15.
  • These third lighting means 15 initially emit a ceiling and the light is reflected back into the room as indirect lighting. In this way, a fairly large area 22 can be illuminated. Usually, the entire space is illuminated by the third light means 15. However, the brightness of this light means 15 is comparatively low.
  • table lamps could also be configured at workstations in a corresponding manner.
  • Decisive here is the combination of the two intended for direct light emission light sources. On the one hand, therefore, large-area, diffused or directed light should be emitted over the larger field. In addition to this, a special area can be specifically illuminated with the aid of the pivoting spot.
