Given the particular considerable mechanical effort in the previously known adjusting devices for selectively aligning electric lamp heads and the only limited degree of freedom offered by these devices, the invention has for its object to provide an improved device for adjustable positioning of a lamp head. In addition to the user-friendly adjustability of a desired positioning and their stable persistence even with everyday low movements should reduce the mechanical complexity and at the same time the adjustability of the lamp head can be extended.

CONFIRMATION COPY Another task is to increase the energy efficiency of an electric lamp and to minimize the glare.

The desired solution must be efficiently produced in series.

Overview of the invention

The device provided for positioning an electric lamp comprises a holder and a lamp head adjustably received thereon. The holder has an end piece, and the lamp head has at least one docking point, which is intended to cooperate with the tail. The interaction between the tail and the at least one dock is based on permanent magnetic attraction.

Hereinafter, specific embodiments of the invention are defined: The tail has the ferromag netic or ferrimagnetic part, and the at least one docking point has the permanent magnet. In an alternative reversal, the tail has a permanent magnet and the at least one docking point has a ferromag netic or ferrimagnetisches part. Finally, the end piece can have a permanent magnet and the at least one docking point can have a further permanent magnet with opposite poling to the first-mentioned permanent magnet.

The end piece is at least in principle spherical, and the at least one docking point is flat or formed as a recess. Alternatively, the end piece has a concave contour, and the at least one docking point is designed to be complementary spherical. In a next alternative, the tail has at least in principle the shape of a ball head, which is provided with a multi-faceted faceting, and the at least one docking point has a complementary surface grid, so that the lamp head can be positioned on the tail in defined graded angular positions. Finally, the end piece can be of a disc or block-shaped blank and the docking points are designed to be complementary, so that the lamp head can be attached horizontally to the end piece at one of the docking points. The holder can extend:

a) standing upwards from a foot part; or

b) pendulum-like downward from a support structure; or

c) arm-like from a support structure laterally into the room.

Particularly advantageously, the end piece has the ferromagnetic or ferrimagnetic part and is of spherical design, at least in principle. In addition, the at least one docking point has the permanent magnet and has a concave contour complementary to the end piece.

In one variant, the lamp head has at least a first outer side with a first docking location and a light outlet area with a second docking location, wherein at least one of the surfaces is provided with lighting means.

If the lamp head is of a plate-like design, the first outer side with the first docking location represents the rear side of the lamp head, while the light outlet surface with the second docking location produces the front side of the lamp head provided with the lamps.

The two docking points are present on a magnetic assembly in the lamp head. The magnetic assembly has at least one permanent magnet, which is preferably made of a mixture of neodymium, iron and boron.

The magnetic assembly is arranged centrally in the lamp head and designed as an insert, which at the same time can have the function of a means for cohesion of the lamp head.

The magnetic assembly consists of:

a) two nearly identical, in principle cylindrical connecting elements, which are intended for screwing together in the lamp head; b) a first connecting member having a female threaded portion and a second connecting member having a screw which is intended for engagement in the female threaded portion of the first connecting element; and c) each connecting element a sleeve part in which a permanent magnet is embedded.

The sleeve part terminates on the one hand with an enlarged diameter flange. The flange surrounds a trough-shaped cavity with an access hole. The permanent magnet has an access hole and at the top a trough-shaped cavity. Opposite the flange, the sleeve part ends with a grid, which surrounds the centrally projecting screw or the complementary connecting element, the internal thread. Externally on the sleeve part a rotation lock is provided. On the flange, an attenuator, preferably a profiled rubber disc may be placed, which has an access hole and above a trough-shaped cavity. The access holes in the attenuator and in the permanent magnet allow access to an engagement contour in the screw. The permanent magnet and the internally threaded part in the first connecting element or the permanent magnet and the screw in the second connecting element are non-rotatably embedded in the respective sleeve part.

The lamps are shielded with a cover and / or a header, wherein at least the cover is translucent and serves to glare and / or light pipe and / or protection. The header may be designed as a reflector so that the light beam is e.g. coronary emerge only at the periphery of the intent.

The lighting means are preferably a concatenated arrangement of LEDs.

In an alternative embodiment, the lamp head has a plurality of outer surfaces, on which in principle any free point can be used as a docking point. The outer surfaces are at least in principle permanently magnetic or ferromagnetic or ferrimagic, while the end piece is designed to be functionally complementary in order to produce the magnetic attraction. The lamp head can be equipped with more than just one of the outer surfaces with bulbs that can be arranged in different grids and / or have different power and / or different color temperature. Switching means are provided to selectively activate the bulbs.

An additional device for adjusting the exit angle of the light to the electric lamp is provided, wherein:

a) in the lamp head at least one light source is arranged;

b) is provided in the lamp head associated with the at least one lamp and intended for directing light lens;

c) the lamp head has an actuator connected to the lens for influencing the exit angle;

embodiment

The detailed description of an exemplary embodiment with constructional alternatives of the device according to the invention for positioning an electric lamp will be given below with reference to the attached drawings. The following definition applies to the entire further description. If reference numerals are included in a figure for the purpose of graphic clarity, but are not explained in the directly associated description text, reference is made to their mention in the preceding or following description of the figures. In the interest of clarity, the repeated designation of components in other figures is usually dispensed with, as far as the drawing clearly shows that they are "recurring" components.

FIGS. 1A to 1K

First, the electric lamp with the inventive device for positioning the lamp head 1 of the holder 17 with the end piece 18 located thereon is only approximated (s. Figures 1A.1 B). Here, the light exit surface 10 with the central second docking point 12 upwards and the outer side 208 with the centric first docking point 11 located there downwards. The light emitted from the light exit surface 10 into the room is thus directed upward, e.g. with narrow exit angle 51. Power is supplied via cable 19. In this configuration, a floor or table lamp results. In the docked state, the lamp head 1 is magnetically held on the end piece 18 of the holder 17 (see Figures 1C.1 D). Conversely, the lamp head 1 can alternatively be magnetically docked at the second docking point 12 on the end piece 18, so that the outside 208 now points upwards, while the light is directed downwards and, for is set at a wide exit angle 52 (see Figures 1 E, 1 F). The magnetic device also allows the almost vertical docking of the lamp head 1 alternatively at the first docking point 11 or at the second docking point 12, so that the light is directed upwards or downwards (see Figures 1G.1 H).

When designed as a pendant light, the bracket 17 is anchored to a support structure T, eg a ceiling. In this case, the first docking point 11 or the second docking point 12 can be attached magnetically to the end piece 18 of the holder 17, this with almost any orientation of the lamp head 1 (see FIGS. 1J.1 K). FIGS. 2A to 3C

The modification in this pair of figures is that the permanent magnet 95 is an integral part of the lamp head 1. Depending on the configuration of the magnetic connection to the lamp, the permanent magnet 95 sits in the lamp head 1 - then the tail 18 is the ferromagnetic or ferrimagnetic counterpart - or vice versa. In this embodiment of the device as well, the luminaire head 1 can be attached to its rear outer side 208 and to the first docking point 11 (see FIG. 2A) or to its front light exit surface 10 and the second docking point 12 (see FIG 18 magnetically attach in almost any orientation. The luminaire head 1 comprises a base 2 with the bottom 20 and the circumferential collar 21. Internally on the bottom 20 of the illuminant carrier 3 is arranged, and on the light exit side 10, a translucent cover 8 is inserted. In the figures 2C to 3C, the permanent magnet 95 is shown in the lamp head 1 as an insert. For the stepwise alignment of the lamp head 1, the docking points 11, 12 may have a grid - e.g. a polygonal socket - and the end piece 18 is designed to be complementary (see Figure 2E). In addition or as an alternative to the translucent cover 8, an attachment 88 can be positioned on the light exit surface 10 (see FIG. 3B). Instead of spherical, the docking points 11, 12 and the end piece 18 may alternatively be of planar shape (see Figure 3C).

FIGS. 4A and 4B

Similarly, only narrower than before, is located as an integral part of the lamp head 1 in the center of a permanent magnet 95, which has on the one hand the first docking point 11 and on the other hand, the second docking point 12 , On the light exit surface 10 with the second docking point 12, the bulbs 34 are arranged, whereby the outside 208 could be equipped with bulbs 34. This lamp head 1 can also be attached with the first docking point 11 on the end piece 18 (see Figure 4A) or can be attached to the end piece 18 with the second docking point 12 (see Figure 6B), wherein in each case the magnetic attraction acts and for the positioning of the lamp head 1 a large degree of freedom in the wished angular position exists. Again, the permanent magnet 95 may be an integral part of the lamp head 1 and the end piece 18 represent the ferromagnetic or ferrimagnetic part. Alternatively, the end piece 18 has the permanent magnet and in the lamp head 1 sits the complementary ferromagnetic or ferrimagnetic part. Finally, permanent magnets with opposite polarity can be provided on both sides, so that in each of the three alternatives, the magnetic attraction causes the attachment of the lamp head 1 on the end piece 20.

FIGS. 5A and 5B

As in the previous pair of figures, the lamp head 1 can optionally be attached to the first docking point 11 on the end piece 18 (see FIG. 5A) or can be attached to the end piece 18 with the second docking point 12 (see FIG. 5B). The principle of magnetic attraction between the permanent magnet 95 and tail 18 is unchanged. The docking points 11,12 are now not concave, but open to the outside conical. Further, the lamp head 1 is here equipped both on the usual light exit side 10 and on the outside 208 with bulbs 34, which may be arranged in a different grid and / or have different power and / or different color temperature. In the corresponding switching state can therefore depart from the lamp head 1 depending on a light beam in two different directions.

FIGS. 6A to 6C

The luminaire head 1, which is now more rectangular in a further variant, can furthermore be either attached to the end piece 18 with its first docking point 11 (see FIG. 6A) or can be connected to the second docking point 12, which is located on the usual light exit surface 10, on the end piece 18 be attached (see Figure 6B). Furthermore, the lamp head 1 can now also be magnetically adhered to the end piece 18 with one of the two narrow-side further outer surfaces 14 on which the further docking stations 13 are located (see FIG. 6C).

First of all, it has been modified that there is no longer a separate permanent magnet 95 with the docking points 11, 12, but in this variant of the Lamp head 1 almost every free point of its outer surfaces 10,208,14,14 as docking point 11, 12,13 is usable. Therefore, all outer surfaces 10,208,14,14 of the lamp head 1 in principle permanently permanent magnetic or procure as ferromagnetic or ferrimagnetisches part, while the end piece 18 is designed to produce the magnetic attraction functionally complementary. In addition, the lamp head 1 is now equipped on all outer surfaces 10,208,14,14 with bulbs 34, which in turn may be arranged in different patterns and / or may have different power and / or different color temperature. Depending on the selected switching state can go from the lamp head 1 of only one to all four outer surfaces 10,208,14,14 a light beam.

FIGS. 7A and 7B

The lamp head 1 consists of the base 2, the illuminant carrier 3, the lens carrier 4, the core piece 5, the carriage 6, the adjusting element 7, the cover 8 and the two connecting elements. 9

The base 2 has a bottom 20 with a central passage 200 and the outside 208. The bottom 20 is bordered by a collar 21 rising from it, so that an interior 28 is formed. A plurality of spaced, stepped webs 22 are provided in the interior 28 at the transition from the bottom 20 to the collar 21 and extend upwardly at the collar 21. A web 22 has adjacent the bottom 20 a projection 23. The webs 22, spaced from the ground 20, together the first guide 24, to the distance of a step, the second guide 25 connects. At the upper free end of the collar 21, a circumferential fourth shoulder 27 is present. The passage 200 in the bottom 20 opens into the interior 28 and the outside 208. The passage 200 has set back from the outside 208 a first radially encircling shoulder 201. At a distance from the first shoulder 201, a positioning member 202 is arranged in the passage 200, here as a cam educated. Approximately at the level of the inside of the bottom 20 is located in the passage 200, a second radially encircling shoulder 203. The passage 200 surrounds, rises from the inside of the bottom 20, a base 204 which extends up to the level of the first guide 24. The base 204 has on the outer circumference a wreath of teeth 205 and ends at the top with a third shoulder 206. At the transition between the bottom 20 and collar 21, a cable access 209 is present as an opening. In the interior 28 are located on the bottom 20, adjacent to the collar 21, a plurality of anchor points 230, preferably in the form of Schraubdomen. The base 2 is produced, for example, as an aluminum casting and forms the housing for the lamp head 1 with simultaneous function as a heat sink for dissipation for the heat generated in the lamp head 1. The ring of teeth 205 on the base 204 increases the heat dissipating surface of the base 2.
