Definitions

  • the invention relates to a luminaire.
  • Luminaires with pivotable lamp shades are of course well known in the art.
  • the lampshade is usually pivotable by a complex mechanism relative to the lamp frame.
  • the luminaire according to the invention has a curved support which points away from the ground in the installed state of the lamp and a lampshade pivotable relative to the support with a corresponding support which is movably mounted on the support.
  • This makes it possible to relatively move the lampshade relative to a lamp frame, which preferably has the curved support and thus to pivot the lampshade in total.
  • the pivot mechanism makes doing so only by the effect of gravitational force by the lampshade presses the corresponding support in the assembled state under the influence of gravity against the support and the resulting friction between support and corresponding support is dimensioned so that the lampshade in different pivot positions slip resting on the support.
  • the lampshade does not need to be additionally locked.
  • the support made of plastic in particular thermosetting plastic, especially bakelite and form the lampshade made of aluminum or steel sheet.
  • the lampshade and the matching support can be made of untreated aluminum or sheet steel.
  • the corresponding edition can also be treated, in particular, it can be enamelled, anodized or painted.
  • the support is at least partially formed as a spherical zone, and the corresponding support is preferably also at least partially formed as a spherical zone.
  • the corresponding support is preferably also at least partially formed as a spherical zone.
  • Under a spherical zone is understood on the one hand exactly a zone of a ball, but also a shape that comes close to the ball zone, as long as the contact surface between support and corresponding support in each pivot position is large enough to slipping the lampshade by the effect of gravity alone to prevent.
  • the support is formed as a completely encircling ball zone, and the corresponding support is then preferably also formed as its adapted, completely encircling ball zone.
  • the lampshade is advantageously vertically pivotable in each horizontal angle along the circumference of the support.
  • Support and corresponding support are adapted to each other along their respective overall extent, thereby forming a particularly large contact surface.
  • the support and the corresponding support have the same curvature throughout their respective extent.
  • a particularly large contact area between the support and corresponding support is produced, which forms a ground-facing edge portion of the spherical zone when just placed lampshade, which preferably makes up about half of the surface of the support.
  • the lampshade is frusto-conical, and the corresponding support is formed circumferentially along a small lampshade opening, preferably the small lampshade opening.
  • the lampshade is particularly inexpensive to produce and beyond particularly aesthetic.
  • the ball-shaped pad has a small opening and a large opening
  • the lampshade has the small lampshade opening
  • a distance between a point of the small opening of the support and a maximum point opposite the large opening the overlay is larger than a diameter of the small lampshade opening.
  • the lampshade placed on the support can not slip off the support in any pivoting position.
  • the small lampshade opening may have a curved edge in the interior of the lampshade, which rests circumferentially on the support. The edge digs as it were in the support and thereby generates a particularly high friction, which counteracts a slipping back of the lampshade from the pivoted position.
  • the edge of the small lampshade opening has a preferably circumferential sharp edge.
  • a friction-enhancing coating may be provided, in particular a felt or rubber coating. This coating can be applied to the support or on the corresponding support.
  • a dome starts from the small opening of the ball-zone-shaped support, and from the dome an electrical cable goes from one end to the support against which the lamp can be suspended from the ceiling with its entire weight.
  • the luminaire frame 2 comprises a socket 4, in which a light bulb 5 is shown in principle drawn in a view. Laterally on the light frame 2, a rotary switch 6 is arranged, with which the electrical power supply of the light bulb 5 can be switched on and off.
  • the lamp 1 has a weight which makes it possible to attach the lamp 1 with its total weight to an electric cable 7 hanging on a ceiling 8.
  • the luminaire frame 2 comprises a dome 40 in the area facing the ceiling 8 and a ball-zone-shaped support 41.
  • the lampshade 3 is placed pivotably on the ball-zone-shaped support 41.
  • the lampshade 3 is frusto-conical and has a small lampshade opening 31 and a large lampshade opening 32.
  • the little one Shade opening 31 is in Fig. 1 the lamp frame 2 facing arranged on the lamp 1, while the large lampshade opening 32 facing away from the lamp frame 2 is arranged on the lamp 1.
  • Fig. 1 shows that the lamp 1 by the gravitational force from the ceiling 8 hanging on her the ground-facing end of the lamp frame 2 has the pivotable lampshade 3.
  • the pivotable lampshade 3 has a corresponding support 33, which in the in Fig. 1 shown assembled state is pulled down under the action of gravity against the support 41 of the lamp frame 2.
  • the support 41 and the corresponding support 33 touch each other in the Fig.
  • the corresponding support 33 and the support 41 are adapted to each other over the entire surface in the form.
  • the resulting from the contact of the support 41 with the corresponding support 33 friction is such that the lampshade 3 according to Fig. 2 can be pivoted in all directions by the lampshade 3 is simply slipped with its corresponding support 33 on the support 41 and maintains its position non-slip by the friction in the pivoted position.
  • a tilted position is in FIG. 2 shown.
  • Fig. 3 shows in a projection on top of each other three different possible positions of the lampshade 3 with respect to the lamp frame 2.
  • the straight position is already in the Fig. 1
  • one of the pivoted positions is in the Fig. 2
  • Fig. 4 shows the light frame 2 according to Fig. 1 in a sectional view.
  • the luminaire frame 2 has the portion facing away from the ground in cross-section perpendicular to a longitudinal direction L circular shaped dome 40 and along its outer wall spherical zone formed pad 41.
  • the ball-zone-shaped pad 41 has at one end facing away from the ground perpendicular to the longitudinal direction circular small opening 43 and at a bottom facing the end of a circular large opening 44.
  • the bulb 5 can be screwed into the socket 4.
  • the socket 4 is arranged inside the dome 40. At the bottom facing away from the end of the dome 40, an opening 42 for the passage of the electric cable 7 and the electric cable 7 is provided in the dome 40.
  • Fig. 5 shows the light frame 2 in a side view. It is the rotary switch 6 is provided, with which the electrical supply of the bulb 5 can be interrupted and made.
