Abstract

A light fixture (10 is shown and described that has a light head (11) holding at least one light source (15) and an installation unit (12) with an installation memory (24) in which data about the light head is written/

The novelty is that the light head (11) has at least one light-head memory (18) separate from the installation memory (20), the data from the light-head memory being writable in the installation memory.

Claims

1. A light fixture (10) having a light head (11) holding at least one light source (15) and an installation unit (12) with an installation memory (24) in which data about the light head is written, characterized in that the light head (11) has at least one light-head memory (18) separate from the installation memory (20), the data from the light-head memory being writable in the installation memory.

2. The light fixture according to claim 1, characterized in that the installation unit (12) is connectable via a signal line (24) with a controller (23) of a control system for a plurality of light fixtures (10, 21, 22).

3. The light fixture according to claim 2, characterized in that the data written in the installation memory (20) is transmittable to the controller (23).

4. The light fixture according to claim 1, characterized in that the data written in the installation memory (29) is taken into account when operating the light fixture (10).

5. The light fixture according to claim 1, characterized in that data is read and written during or after making a connection (19) between the light head (11) and the installation unit (12).

6. The light fixture according to claim 1, characterized in that the installation unit (12) is an operating unit, in particular an electronic power-supply circuit, for the light head (11) (FIG. 1).

7. The light fixture according to claim 6, characterized in that the installation memory (20) is provided in the operating unit (FIG. 1)

8. The light fixture according to claim 1, characterized in that the installation unit (12) is separate from the operating unit (40) for the light head (11) (FIG. 5).

9. The light fixture according to claim 8, characterized in that the installation unit (12) has a signal-line connection (41) separate from a signal-line connection (42) of the operating unit (40) (FIG. 5).

10. The light fixture according to claim 1, characterized in that a connection (19) between the light head (11) and the installation unit (12) is releasably made via electrical lines (19, 31, 32).

11. The light fixture according to claim 10, characterized in that the electrical lines (31) are constituted as data lines (FIG. 3).

12. The light fixture according to claim 1, characterized in that the light head (11) is connected with the installation unit (12) via voltage-supply lines (32).

13. The light fixture according to claim 11, characterized in that the data lines (31) are separate from the power-supply lines (32).

14. The light fixture according to claim 11, characterized in that the existing voltage-supply lines are used as data lines.

15. The light fixture according to claim 1, characterized in that the a signal connection is provided between the light head (11) and the installation unit (12) for reading the light-head memory (18) via electromagnetic waves (FIG. 4).

16. The light fixture according to claim 1, characterized in that a plurality of light heads (11) are connected with one installation unit (12).

17. The light fixture according to claim 16, characterized in that the plurality of light heads each have their own light-head memories.

18. The light fixture according to claim 1, characterized in that the light head (11) is formed of several elements, such as a reflector 914), light source (15), cover glass (17a, 17b) and the like.

19. The light fixture according to claim 18, characterized in that several elements (14, 15, 17a, 17b) of a light head (11) each have their own light-head memory (25, 26, 17).

20. The light fixture according to claim 19, characterized in that the installation memory (29) can receive the data from several light-head memories (25, 26, 27).

21. The light fixture according to claim 20, characterized in that data is transmitted through the data line (24) according to the DALI protocol.

22. The light fixture according to claim 1, characterized in that the light-head-related data includes data about the type and kind of light head (11) or about the type and kind of a part (14, 15, 17a, 17b) of a light head (11).

23. The light fixture according to claim 22, characterized in that the light-head-related data includes an identification number for the light head (11), inn particular a product number of the light head.

24. The light fixture according to claim 1, characterized in that the light-head-related data includes an individualized identifier for the light head (11) to make it individually identifiable.
