The Fig. 1 to 16 show a first embodiment of a lighting device according to the invention. As essential components, the lighting device provides a fixing body 1, a lamp body 2 pivotally mounted on the fixing body 1, two illuminants 3 fixed in the lamp body 2, and a terminal unit 4 held on the lamp body 2. The lighting means 3 are in particular designed as LED lighting means 3. The connection unit 4 serves for contacting and driving the lighting means 3.

The lighting device is designed for example as a ceiling light and provided for overhead mounting. Here, the fastening body 1 is fixed to a ceiling. For connecting the lamp body 2 with the fastening body 1, a pivoting module is provided. Next, a locking module is provided for fixing the lamp body 2 in an operating position thereof.

Alternatively, the mounting body 1 can be mounted on another external attachment or provided hanging in space.

If the lighting device is used for ceiling mounting, are in the operating position of the mounting body 1 and the lamp body 2 in a horizontal extension. The lamps 3 are provided on the lamp body 2, that light of the lamps 3 is emitted laterally and downwards. In order to enable assembly and maintenance of the lighting device, the lighting device can be moved from the operating position to the open position. Here is the fixed to the ceiling fixing body 1 unchanged in a horizontal extent, while the lamp body is substantially vertically extending, cf. Fig. 10 ,

To realize the pivotal fixing of the lamp body 2 to the mounting body 1, the pivoting module comprises two mutually spaced fixed to the mounting body 1 retaining arms 5. The support arms 5 are U-shaped. You see one each connected to the mounting body 1 holding leg 6, a holding leg 6 opposite free leg 7 and a middle leg 8 for connecting the holding leg 6 with the free leg 7 before. In the ceiling-mounted state of the fastening body, the U-shaped retaining arms 5 protrude at the edge from the fastening body 1 in such a way that a channel closed downwards is formed by the U-shape.

The pivoting module further comprises two receiving openings 9, wherein the receiving opening 9 are provided in a distance corresponding to the distance of the retaining arms 5. The receiving openings 9 are provided on the lamp body 2. The retaining arms 5 are used for fixing the lamp body 2 to the mounting body 1 in the receiving opening 9. In particular, by the geometry of the support arms 5 and the receiving opening 9 ensures that the lighting device is protected against unintentional disassembly. In particular, a width c of the receiving openings 9 is greater than a length h of the free legs 7 and at the same time smaller than a length b of the center leg 8. This ensures that the holding arms 5 in the open position of the lighting device in the then substantially vertically extending receiving opening. 9 can be used. At the same time it is ensured that the retaining arms 5 can not be removed from the receiving openings 9 in the operating position.

In the operating position, the essentially cuboid lamp body 2 projects beyond the fastening body 1 formed by way of example by an L-shaped, closed frame at the edge. In order to ensure pivoting of the lighting device in the open position and the mounting of the lamp body 2 or a hooking the same in the hook (holding arms 5), is a formed between an outer edge 10 of the pivotally mounted lamp body 2 and the receiving opening 9 edge portion r smaller than a between the mounted in the assembled state of the ceiling facing free leg 7 and provided for the ceiling mounting surface 11 of the mounting body 1 specific Montagemaß s.

As part of the locking module, the lighting device provides a first locking element 12 and a second locking element 13. In each case, the locking elements 12, 13 spaced from each other are rotatably held on the lamp body 2. Rotary axes 14 of the locking elements 12, 13 are provided parallel to each other. As part of the locking module, two locking recesses 15 provided at a corresponding distance from the locking elements 12, 13 on the fastening body 1 are also provided.

For locking the lamp body 2 to the mounting body 1 in the operating position, the locking elements 12, 13 are spent in the locking position, for example 3 and 4 , In the locking position, a first leg 16 of the locking elements 12, 13, which serves as an actuating leg of the locking elements 12, 13, provided behind the lamp body 2 concealed. A second leg 17 of the locking elements 12, 13, which is designed in the manner of a locking leg 17, engages in the latching recess 15 on the fastening body 1 and thus prevents the lamp body 2 can be pivoted away from the mounting body 1.

In particular, the locking elements 12, 13 are mutually pivotable. The first locking element 12 is rotated by turning it clockwise from a release position, which is exemplified in Fig. 1 is reproduced, spent in the locked position. The second locking element 13 is pivoted by turning it in the counterclockwise direction from the release position into the locking position. By the locking leg 17 of the locking elements 12, 13 rests in the locking position on a boundary edge 18 of the locking recess 15, resulting in the locking position of the locking elements 12, 13 in particular by the opposite operation of the same centering of the lamp body 2 to the mounting body 1 and a tolerance compensation.

A by two further, opposite boundary edges 19, 20 formed boundary edge pair of the recess 15 is partially funnel-shaped tapered. This ensures that the locking elements 12, 13 are guided in the locking position along a boundary edge 19, 20 of the boundary edge pair when they are moved. The funnel-shaped tapered boundary edge pair provides so far for a small gap in the operating position in the lighting device and a high-quality appearance of the same.

The correct locking of the lamp body 2 to the mounting body 1 in the operating position can be visually checked in a particularly simple manner. As stated, the locking elements 12, 13 are completely covered in the operating position by the lamp body 2, provided that the locking elements 12, 13 are correctly in the locked position. On the other hand, if the locking elements 12, 13 are in the release position or are they located between the release position and the locking position, the locking elements 12, 13 protrude in sections over the lamp body 2 at the edge. This protrusion can be easily recognized visually. To realize the optical control option, a length I of the actuating lever 16 of the locking elements 12, 13 is matched to the position of a pivot point 32 of the locking elements 12, 13. The actuating leg 16, which extends in the locking position parallel to a peripheral edge of the lamp body 2, pivots in particular with the angled formed free end during pivoting of the same over the lamp body 2 also.

The locking elements 12, 13 are designed in particular as sheet metal bent parts. In addition to the first leg 16 and the second leg 17, two guide lugs 21, 22 are provided as part of the locking elements 12, 13, which in correspondingly shaped, ring-segment-shaped recesses 23, 24 of the lamp body 2 intervene and be guided in this. In particular, the locking elements 12, 13 are formed so that a defined release position of the same results as soon as an inner guide lug 21 bears against a stiffening rib 25 of the luminous means 3 and blocks the pivoting movement of the locking elements 12, 13.

A positive fixing of the locking elements 12, 13 in the locking position via a latching edge 26, which is provided on an elongated recess 27. The recess 27 is formed on the mounting body 1 and serves to receive the actuating arm 16. In the locking position, the locking edge 26 surrounds the actuating arm 16 and secures it against inadvertent release.

If a lighting device according to the invention is mounted suspended from a ceiling, for example, hanging, the fastening body 1 on the side facing the ceiling (mounting surface 11) may be formed closed. A corresponding alternative embodiment of the lighting device according to Fig. 17 shows a corresponding variant. Due to the closed design of the fastening body 1 in the region of the mounting surface 11, contamination of the lighting device, in particular in the region of the connection unit 4 and a functional impairment, is prevented on the one hand. On the other hand, the lighting device gets a higher-quality appearance.
