Description

[0040] The present invention will be explained in more detail below on the basis of an exemplary embodiment with reference to the attached drawings. These show the following:

[0041] FIG. 1: A side cross-sectional view of an embodiment of the illumination device according to the invention, and

[0042] FIG. 2A perspective view of the illumination device according to the invention.

[0043] In FIG. 1, an illumination device according to the invention is generally designated by the reference number 10. The illumination device 10, which is shown in FIG. 1 in a side cross-sectional view, comprises a base body 12 and a plurality of light modules 14 arranged thereon, which are adapted to emit light. Furthermore, in the embodiment shown here, the illumination device 10 comprises two functional units 16.

[0044] The functional units 16, of which only one can be seen in FIG. 1, are intended to be optionally inserted into a receptacle 18 of the base body 12. A functional unit 16 can be attached to the base body 12 via a mechanical interface 20 which is configured substantially in the same way on the functional units 16, the mechanical interface 20 matching the receptacle 18 being formed as a simple, substantially cylindrical portion in the embodiment shown here.

[0045] Also, disconnection of the functional unit 16 from the base body 12, for example in order to replace it with another functional unit 16, can be ensured by the mechanical interface 20 and the matching receptacle 18. For example, it is conceivable that an elastic element, such as a spring, is provided on the receptacle 18, which preloads the respective functional unit 16 in the removal direction from the receptacle 18.

[0046] In the embodiment shown, the functional unit 16 is connected to and/or disconnected from the receptacle 18 of the base body 12 without tools by simply inserting it into and removing it from the receptacle 18.

[0047] In a possible embodiment, one of the two functional units 16 can be a spotlight with a more focused illumination field compared to the illumination field of the light modules 14 of the base body 12. The other of the two functional units 16 can be a laser light emission unit that projects a specific pattern, which in the simplest case is at least one dot, onto a surface. This means that the illumination device 10 can be equipped or converted for a wide range of applications with different requirements.

[0048] In addition to the mechanical interface 20, the illumination device 10 can also have an electrical interface 22, which is adapted, for example, to supply power to the respective functional unit 16 accommodated in the receptacle 18. It is also conceivable that signals generated by this functional unit 16 are transmitted via the electrical interface 22 to the base body 12 of the illumination device 10 and, if necessary, subsequently to an associated control unit (not shown). For this purpose, the receptacle 18 shown in FIGS. 1 and 2 comprises a corresponding electrical mating interface 24. Of course, the electrical interface 22 or the electrical mating interface 24 can also correspond with portions of the mechanical interface 20 or the receptacle 18 which are provided, for example, in the mechanical interface 20 and the receptacle 18 to prevent rotation of a respective functional unit 16 mounted in the receptacle 18.

[0049] The illumination device 10 comprises a light-emitting surface 26, at which the light emitted by the light modules 14 can emerge from the base body 12. On the side opposite the light-emitting surface 26, the base body 12 has a rear surface 28. In the embodiment shown here, the receptacle 18 is arranged on the rear surface 28 of the base body 12, thus allowing the insertion or removal of a functional unit 16 on the rear surface 28.

[0050] A cover 30 is also shown in FIG. 1. Here, the cover 30 is inserted into an opening 32 arranged in the rear surface 28. The cover 30 can thus close the receptacle 18 and seal the base body 12, in particular fluidically, on the receptacle 18. The cover 30 is configured here as a component separate from a respective functional unit 16. However, it is also possible that a cover 30 is permanently connected to a respective functional unit 16 or even formed integrally with it. In this way, a separate cover 26 could be provided for each functional unit 16 in order to close the receptacle 18.

[0051] The cover 30 can be connected to the receptacle 18 via connecting means (not shown). For example, the receptacle 18 can have projections which are adapted to interact with corresponding recesses on the cover to hold it in the receptacle 18. Of course, the recesses and projections can also be arranged on the other element of the receptacle or cover or on both. For example, the recesses can be configured and the cover 30 spring-loaded such that a combined pushing and turning movement is required in order to release the cover 30 from the receptacle 18. This prevents unintentional release of the cover 30 from the receptacle 18.

[0052] FIGS. 1 and 2 also show a handle 34, which is connected here to the base body 12 of the illumination device 10 on the side of the light-emitting surface 26. The base body 12 can be positioned in space using the handle 34. Furthermore, the handle 34 can be used to control the respective functional unit 16, for example to change a respective functionality. It is therefore conceivable that turning the handle 34 can adjust the focus of the spotlight in the case of a spot lighting functional unit 16 and cause the light spectrum to change in the case of a functional unit 16 that emits light in only one predetermined light spectrum.

[0053] FIG. 2 shows a perspective view of the illumination device 10 according to the invention.

[0054] The two functional units 16 are shown in FIG. 2. A respective functional unit 16 can optionally be inserted into the receptacle 18 of the base body 12 (see dashed line from the functional units 16 to the receptacle 18).

[0055] FIG. 2 also shows that at least some of the light modules 14 can be accessed via the opening 32 on the rear surface 28 of the base body 12, so that the opening 32 can also serve as an access opening for maintenance and repairs to the light modules 14.
