Abstract

A light fixture (10, 10a, 10b, 10c, 10d, 10e, 10f) is shown and described that is connectable via a signal line (11) with a controller and that has an electronically readable memory (15) holding an identifier of the light fixture, the identifier being transmittable via the signal line (11) to the controller (12).

The novelty is at least in part that the identifier is also held in a secondary memory (16, 19, 19b) associated with the light fixture.

Claims

1. A light fixture (10, 10a, 10b, 10c, 10d, 10e, 10f) connectable via a signal line (11) with a controller and having an electronically readable memory (15) holding an identifier of the light fixture, the identifier being transmittable via the signal line (11) to the controller (12), characterized in that the identifier is also held in a secondary memory (16, 19, 19b) associated with the light fixture.

2. The light fixture according to claim 1, characterized in that the identifier is readable from the secondary memory (16, 19, 19b) when the light fixture is installed and/or put into service.

3. The light fixture according to claim 2, characterized in that the identifier is manually readable from the secondary memory (16, 19, 19b) when the light fixture is installed and/or put into service.

4. The light fixture according to claim 2, characterized in that the identifier is readable by a portable device from the secondary memory (16, 19, 19b) when the light fixture is installed and/or put into service.

5. The light fixture according to claim 1, characterized in that the identifier is readable from the secondary memory electronically and/or electromagnetically and/or optically.

6. The light fixture according to claim 1, characterized in that the identifier read from the secondary memory is transmittable via a transmission path (22) separate from the signal line to the controller.

7. The light fixture according to claim 1, characterized in that the identifier is transferred from the secondary memory to the controller indirectly, for example manually by use of a ceiling plan (20) or by means of a reader (17).

8. The light fixture according to claim 1, characterized in that the secondary memory is part of a label (19) or is formed as a label (19).

9. The light fixture according to claim 1, characterized in that the identifier is held in the secondary memory as a character code, in particular a bar code, and is printed on a label.

10. The light fixture according to claim 1, characterized in that the secondary memory is an RFID chip.

11. The light fixture according to claim 1 characterized in that the secondary memory is separable from the light fixture (10, 10a, 10b, 10c, 10d, 10e, 10f) or is carried on a part associated with the light fixture, in particular its packaging.

12. A light fixture (10, 10a, 10b, 10c, 10d, 10e, 10f) connectable via a signal line (11) with a controller and having an electronically readable memory (15) holding an identifier of the light fixture, the identifier being transmittable via the signal line (11) to the controller (12), characterized in that there is for the light fixture a further transmission path (22, 17) independent of the signal line and through which the identifier can be read during or after final installation of the light fixture.
