task

The present invention is therefore based on the object to provide a lighting device that allows a more flexible use over the prior art. solution

The underlying object is achieved on the basis of a lighting device of the type described above according to the invention that the Nebenieuchtorgan in force transmitting manner and non-destructive solvable with. the housing is connectable. Conversely, the Nebenieuchtorgan is also destructively removable from the housing.

It is understood that the non-destructive connection allows repeated assembly and disassembly of the auxiliary light on the housing of the lighting device. In this way, the invention offers the particular advantage that a respective

Lighting device can be provided with a Nebenieuchtorgan if necessary and not necessarily be equipped with a just such. In this way, it is possible for a supplier to keep a certain number of always the same lighting equipment and only a smaller number of secondary lighting organs. In this way, the lighting devices are flexible and economical to use.

Furthermore, the invention offers the particular advantage that one and the same

Lighting device can be equipped as needed with different Nebenieuchtorganen. The latter may differ, for example, in the type of light effects that can be produced, with different variants being desired depending on the field of use.

It is also possible to supplement or replace the non-destructively removable or reversely non-destructively mountable additional luminous elements with already permanently installed lighting devices. In this way, an operator of

 Set lighting equipment particularly flexible to a pending event or the like.

In an advantageous embodiment of the lighting device according to the invention, the secondary lighting device is designed in the form of a light ring, which has a plurality of annularly arranged around a center Leuchtmiitei. Preferably, the Leuchtmitiel are arranged in a plane, Such a "light ring" is particularly well suited

Main luminous organ of the lighting device optically enclose and to produce in this way around the Hauptieuchtorgan circumferential optical effects.

[13] In a particularly advantageous embodiment, the lighting device comprises at least one positive locking means, by means of which the secondary lighting device can be fastened to the housing of the lighting device. Advantageously, at least two such Formschiussmittel are provided to accomplish a removal of torque loads by means of the formation of a pair of forces on the interlocking means particularly easy to körinen. It should be noted that especially in the fold of the use of a Nebenieuchtorgans on a highly dynamic moving head quite substantial

Accelerations and thus inertial forces can act on the secondary lighting device. Accordingly, it is of particular importance that the auxiliary luminous element is securely fastened to the housing. Since associated luminous devices are often suspended at considerable height above the floor, for example on a ceiling, it is of particular importance that the secondary luminous element is protected against falling down.

The formation of a positive connection equally allows a particularly safe and a particularly simple manner of attachment, which can also be carried out without destruction non-destructive. [15] If two positive locking means are used, it is also particularly advantageous if they are located opposite each other with the secondary luminescent device

interact. In this way, a force acting on the secondary luminous element is particularly easy to derive. In addition, it is mitteis the opposite arrangement of the positive locking means possible to clamp them to some extent against each other. This is before old then advantageous if the secondary light-emitting device is rotationally symmetrical, for example, according to the type of a light ring described above.

Basically, regardless of the number of interlocking means used are those of advantage, which are designed in the form of a tongue and groove system Mitteis such a system, it is possible, the Forroschius between the secondary luminescent body and the housing directly, that is without separate Connecting means, to be produced.

 Instead, the auxiliary luminous element and the housing have a form-fitting element acting as a spring and a form-locking belt acting as a groove, wherein the

Nebenleuchtorgan and the housing each have one of these elements. It is basically of secondary importance, at which the Teite the positive-locking element in the form of the groove and on which the Formschlusseiement is arranged in the form of the spring. In order to avoid the presence of the Nebenieuchtorgans in a disassembled state possible on the housing freely projecting elements, it is nevertheless advantageous if the positive-locking element in the form of the spring on the auxiliary light organ and the

Formschlusseiement in the form of the groove to be arranged on the housing, the Formschlusseiemeni in the form of the spring may in particular be formed by a: pin, for example a rod-shaped pin with a rotationally symmetrical cross section, in this way is no special orientation of the positive locking element relative to the other Form-fitting required. Analog can do that

Formschlusseiement be formed in the form of the groove of a recess whose Cross-section is formed complementary to the spring. Advantageously, the auxiliary luminous element comprises two mutually opposite form-fitting elements, which are designed in the form of pins, wherein each longitudinal axis of the pin forms an angle together with a plane which includes the luminous axis of the main luminous element. Furthermore, such a lighting device may be advantageous, having two mutually opposite mounting tabs, which are adapted to each encompass the housing laterally or .. border. Preferably, the Formschiussmittel cooperate with the mounting tabs. The mounting tabs can serve depending on the design of the respective lighting device mainly to guide the respective arranged on the Nebenleuchiorgan Formschlusseiemente in a suitable fvlontagebereich on the housing to which the arrangement of the complementary Formschiusselements of the housing is particularly easy. In particular, in an application in which the

Secondary light organ is designed in the form of a luminous ring, which is arranged at a front end of the housing to optically enclose there main luminous organ, the mounting tabs can serve to relocate a mounting point for the Formschiussmittel towards a central region of the housing, so that the introduction of force

Secondary light organ in the housing does not have to take place directly at the front end of the latter,

[19] Advantageously, a form-fitting element disposed on the housing is adapted to the housing such that it can be positioned in a unique position relative to the housing. Such a training is especially advantageous if the

Secondary luminescent organ to be retrofitted to the lighting device. In cases where the force transmitting connection between Nebenleuchiorgan and housing is subjected to high dynamic forces, a game between the positive locking elements of the (or) Formschiussmittel (s) is generally unacceptable to the security against accidental dropping of the secondary luminaire not compromise. The positioning of the Formschiusselements on the housing must therefore be made with particular precision. Preferably, the form-fitting element comprises a

Positioning portion, for example in the form of a groove which can engage with a complementary trained Postiionierungsabschnitt of the housing, for example in the form of a spring, and is uniquely positioned in this way.

[20] The lighting device according to the invention further ausgestaltend includes their

Nebenleuchtorgan its own electrical connection, by means of which the

Secondary luminescent organ at least with electric current, preferably also with

Control signals, can be supplied. The electrical connection of the secondary luminescent organ is It is independent of the electrical connection of the main luminescent organ. In this Wesse the Nebenieuchtorgan particularly easy to a Leuchieinrichtung

be retrofitted.

[21] For a safe guidance of an electrical line which connects the electrical Anschiuss the Nebenleuchtorgans with the or the Leuchimtitel (s) of the auxiliary light organ, it is also advantageous if the electrical line is guided at least along part of its length within the housing , The inner guide avoids, in particular, an unintentional entanglement of the electrical line and an undesired spin around it in the course of movement of the housing relative to the stator of the

Leuchieinrichtung, Preferably, the housing has an opening through which the electrical conduction of the secondary light-emitting device in the interior of the housing is feasible.

In a particularly advantageous embodiment of the lighting device, the Nebenieuchtorgan can be assembled and disassembled without tools. In this way, it is not necessary for assembly and / or disassembly, a tool vorzuhalten

For example, a screwdriver or the like. In particular, when dealing with light fittings installed at some height above the floor under a ceiling, this is particularly advantageous because a person undertaking assembly / disassembly who is likely to use a ladder does not have to handle tools.

The underlying object is further according to the invention by means of a

Secondary light organ solved that

[25] The lighting device according to the invention will be described below with reference to a

Aueführungsbeispiels, which is shown in the figures, explained in more detail. It shows:

 1 shows a side view of a lighting device according to the invention,

 2 shows a front view of the lighting device according to Figure 1,

 3 shows a detail of a front region of the lighting device according to FIG. 1 in a side view rotated by 90 ° with respect to FIG. 1, FIG. 4: half section of the front region according to FIG. 3 and FIG

 5 shows an exploded view of the front area of the lighting device according to FIG. 1.

[26] An embodiment shown in Figs. 1 to 5 comprises a

Lighting device 1 with a stand 2 and a housing 3. The housing 3 is movably mounted relative to the stator 2. For this purpose, the housing 3 and the stator 2 cooperate mitteis a storage fork 20, on which a total of two joints 21, 22 are formed. These joints 21, 22 allow rotation of the housing 3 relative to the

Stand 2 to two linearly independent axes of rotation, so that a light axis 8 of the lighting device 1 is free to move in space. Such a trained lighting device 1 is also referred to as a so-called "moving head".

[27] A plurality of electrical terminals 7 are formed on the stator 2.

These connections 7 are suitable for supplying both motor drives of the lighting device 1, which are not shown separately in the figures, as well as at least one main luminescent element 4 with electric current. Furthermore, it is possible to supply the lighting device 1 with a control signal which serves to control both the motor drives and the main luminous element 4. The motor drives can be provided in particular in order to move the housing 3 relative to the stand 2 about the two axis of rotation of the joints 21 22.

[28] In the housing 3, the main luminescent member 4 is arranged. This main illuminator 4 emits light in the direction of the illuminated axis 6. Further, at a front end of the

Housing 3 a Nebenieuchtorgan 5.angeordnet, which is connected in force transmitting manner with the housing 3. This Nebenieuchtorgan S is here formed by a light ring, in which a plurality of luminous means 8 are arranged on a luminous means support 18 in a circle around a center as well as in a common illuminating medium support plane 9. This results particularly well from BgurJJ.

[29] The auxiliary luminous element 5 and the housing 3 are connected to each other by means of two form-fitting means 10. In the example shown, these interlocking means 10 cooperate in each case with a mounting lug 17 of the secondary luminescent device 5 on one side and the housing 3 on the other side. The mounting tabs 17 extend at an angle 19 relative to the Leuchtrniftelebene 9, wherein this angle 19 is approximately 75 ° here. The form-fitting means 10 each comprise two form-fitting elements 11, 12, wherein in each case one positive-locking element 12 of a positive-locking means 10 on the housing 3 and the other positive-locking element 11 on the associated mounting strap 17 of the

Nebenleuchtorgans 5 are arranged. The interlocking elements 11, 12 are particularly well based on the exploded view of Figure § and are explained in detail below. [30] In addition to the electrical connections 7, the stator 2 also has an electrical connection 14. This serves to supply the auxiliary luminaire S with electric current and the activation of the auxiliary luminous element 5. The electrical connection 14 is connected to the auxiliary luminous element 5 by means of an electrical line 1S connected. This is guided in the example shown on a part of its length within the housing 3 and on a part of its length within the housing 3. At the electrical line 15 extends from a Anschlußiasche 32 thereof to an opening 16 of the housing 3. There, the electrical line 15 is guided inwards, so that it is invisible from outside the housing 3. Wetterhin the line 1 S is guided through the housing 3 in the storage fork 20 and from there into the stator 2, where it is connected to the electrical connection 14. Since the stand 2 itself is stationary, that is, in the operation of the lighting device 1 does not move, here can the electric

Terminal 14 particularly easy to be connected to corresponding external control devices or the like.

[31] The positive-locking element 11 is here formed by a spigot element which can cooperate in a form-fitting manner with the other form-fitting element 12, the latter being designed in the form of a plate element. This plate element comprises a total of three recesses, namely two lateral recesses 29 and a central recess 24. The soap recesses 29 are adapted to attach the positive-locking element 12 to the housing 3 of the lighting device 1, in particular to screw it to the housing 3. In this way, the positive-locking element 12 can be particularly simple be permanently disposed on the housing 3. Meanwhile, the form-fitting element 11 in the form of the pin element can be connected to the secondary luminous element 5 particularly easily. For this purpose, the secondary luminescent device 5 has at its mounting tabs 17 each have a Äusnehmung 23, which is adapted to cooperate with a thread 30 of the Formschiusseiements 11. In an assembled state, a pin 31 of the form-locking element 11 projects through the recess 24 of the forming member 12 into an end recess 28 which is formed on the housing. The form-fitting connection formed in this way enables the transmission of forces between the housing 3 and the auxiliary light-emitting device S. The mounting state of

Nebertleuchtorgans 5, in which the Formschlusseiemente 11, 12 cooperate, are particularly well recognizable in Figures 3 and 4.

[32] In the example shown, only the positive-locking element 11 can be rotated out of the recess 23 in order to disassemble the secondary humerus 5. For this purpose, the positive-locking element 11 has a rotary ring 25,. for a better manual exercise of torque upper one opposite the pin 31 significantly enlarged

Diameter.

[33] In the example shown, the form-locking element 12 comprises a

Positioning portion 13, which is formed here in the form of an elongated constriction. This positioning portion 13 is kompiementär formed to a strip 27 which is arranged on the housing 3. The constriction of the positioning portion 13 and an upper end of the strip 27 fit together form-fitting, so that the

Positive locking element 12 is clearly positionable on the housing 3 before it is connected in force transmitting manner with the latter. In this way it can be ensured that the secondary luminescent device 5 is arranged in a unique position relative to the housing 3 and the main luminescent member 4. It will be understood that for the clear positioning of the forming member 12 on the housing 3, other

Positioning aids are conceivable. LIST OF REFERENCE NUMBERS
