  • the filament can be on a base, a stand or adjustable or rigid arm so attached by the filament that is connected to at least one Slot is fitted, rigidly or preferably over the light source or is rotatably attached.
  • At least one outer tube can be on the inner tube preferably be attached so that the outer tube or tubes also with slots can be equipped so that they can preferably rotate on the inner tube and / or to be pushed.
  • the lamp according to the invention preferably made of metal, especially light metal, such as one Aluminum alloy - with the exception of the halogen lamp including base, threaded tube, electrical Leads and the like.
  • the light opening in the wall is designed in such a way that a movement of the outer body creates a light gap, the gap width of which can be varied depending on the position of the outer body and light opening of the wall.
  • extremely thin light gaps can be set.
  • the adjustable light gap is linear, so that, contrary to the prior art described at the outset, a defined gap shape results.
  • a reflector in relation to the light exit opening or the light exit gap is arranged behind the lamp, such that the lamp is always between Reflector and light outlet opening.
  • the diaphragm means can be moved inside or outside the body are arranged. In the final function, this is the same, but in one or other form have structural advantages
  • the lamp body is a hollow cylinder and the outer body or bodies each form a ring or a sleeve, which the Encloses the wall of the lamp body and the light opening depending on their position more or less obscured, so that the shape and size of the outward falling Light beam is determined by the respective position of the outer body or bodies.
  • the one forming the wall Luminaire body has a first longitudinal slot with at least one Longitudinal slot of the outer body by turning or pushing more or less to Cover can be brought. This shows that at least in Outer body several slots of different sizes can be provided.
  • an inner sleeve can be provided, which may still be in the Luminaire body is insertable, and has several different openings, for example round, or with other geometrical shapes in front of the gap are rotatable, with which different spot shapes can be shown.
  • the Luminaire body, the outer body and the aperture means in your exterior and / or Inner dimensions matched to each other so that these parts like a functional design kit are interchangeable, and the parts are at least slidable / rotatable with one another with a sliding fit.
  • the lamp according to the invention is an important aid for object photography.
  • the invention allows only minimal scattered light.
  • the lamp according to the invention is economical, ie it has a low energy consumption (5-10 watts).
  • the lamp according to the invention is space-saving, and it can be installed in practically any place.
  • the production of a luminaire according to the invention is possible with little expenditure of material and labor.
  • the new lamp allows very easy handling.
  • the lamp according to the invention is an independent device and does not require any modifications or internals or the like.
  • the lamp according to the invention can be easily carried or transported (Portability).
  • the lamp according to the invention can also be used as a table or with extended base as a standard lamp as well as emergency lighting or night lighting use.
  • FIG. 1 shows the basic concept of the lamp according to the invention. Is on a pedestal a threaded tube 3 or a telescopic holder for the lamp, i.e. preferably a halogen lamp 4 is arranged. This is optional but not mandatory the height position of the lamp within the lamp adjustable. Then that's it Illuminant surrounded by an outer body 12.
  • the outer body contains one Slit, which in this example with sliding aperture means 13, 14 in this Representation is closed. However, these aperture means are in any gap width can be pushed open and closed.
  • This outer body 12 receives the lamp body 8, which is fully inserted into the outer body 12.
  • the lamp body surrounds the illuminant arranged in the interior of the outer body then directly. Also the lamp body has a slot.
  • the outer wall of the lamp body 8 and the inner wall of the outer body 12 are in the sense of a sliding dimension in the Dimensions matched so that they fit snugly, but still light are movable.
  • the lamp body 8 is now rotatable in the outer body.
  • the Rotational position to each other then releases a resulting slot width to the outside, so that even the smallest vertical gap widths can be set. If so Aperture means 13, 14 are also pushed on, then there is also a additional adjustability of the slot length. This can be set to the extent that only one smallest spot can be set in one slot.
  • a multi-stage base 1 a lamp is provided with a threaded tube 3, which in a central Opening 2 with internal thread is screwed in.
