Abstract

A luminaire includes at least one main illuminant and at least one auxiliary illuminant. The main illuminant is provided for a continuous operation. The auxiliary illuminant is controlled by a motion sensor, which activates it when movement is detected. Preferably, the motion sensor is embedded in the luminaire. Furthermore, it is preferred that the at least one auxiliary illuminant is designed as a LED-luminaire.

Claims

1. A luminaire comprising:

at least one main illuminant, in particular a halogen luminaire or LED-luminaire, and at least one auxiliary illuminant, characterized by wherein at least one motion sensor activates the at least one auxiliary illuminant when a movement is detected.

2. The luminaire according to claim 1, wherein the motion sensor is embedded in the luminaire.

3. The luminaire according to claim 1, wherein the at least one motion sensor is designed in the form of a video or thermal imaging camera.

4. The luminaire according to claim 1, wherein the at least one motion sensor is designed in the form of a light barrier, with a plurality of light barriers preferably being provided whose light beams form a light grid.

5. The luminaire according to claim 1, wherein the at least one auxiliary illuminant is designed as a LED-luminaire.

6. The luminaire according to claim 1, wherein the at least one auxiliary illuminant is deactivated by the motion sensor when it detects no movement, optionally after the expiry of a time period.

7. The luminaire according to claim 1, wherein the motion sensor is coupled to the at least one auxiliary illuminant via a control device.

8. The luminaire according to claim 7, wherein the control device deactivates the at least one auxiliary illuminant after the expiry of a time period—

calculated from the last motion detection by the motion sensor.

9. The luminaire according to claim 7, wherein a wireless connection exists between the motion sensor and the control device.

10. The luminaire according to claim 1, wherein the motion sensor and/or the control device is/are connected to a control computer via a data bus, in particular via a LAN.

11. The luminaire according to claim 10, wherein the protocol transmitting the data via the data bus is DMX, Bluetooth or a similar suitable protocol.

12. The luminaire according to claim 10, wherein data about the operating times and/or the switch-on and switch-off times of the at least one auxiliary illuminant and/or signals of the motion sensor are transmittable to the control computer and are storable therein in a suitable memory module, in particular in an EPROM or an EEPROM.

13. The luminaire according to claim 10, wherein the data about the operating times and/or the switch-on and switch-off times of the at least one auxiliary illuminant and/or the signals of the motion sensor and/or the images taken by the video or thermal imaging camera are evaluable using suitable programs and are displayable on an output device, in particular on a screen of the control computer.

14. The luminaire according to claim 1, wherein the at least one main illuminant and/or the at least one auxiliary illuminant is/are designed as an illuminant variable in colour, wherein a change in colour can be activated by the motion sensor.

15. The luminaire according to claim 1, wherein the at least one main illuminant and/or the at least one auxiliary illuminant is/are operable in at least one selectable sequence.

16. The luminaire according to claim 15, wherein the at least one sequence comprises one or several of the following operations:

dimming, a change in intensity, a change in colour, a delay in switching on and/or switching off.

17. The luminaire according to claim 1, wherein the at least one main illuminant is operable in a continuous operation with a selectable basic illuminance.

18. The luminaire according to claim 1, wherein the at least one auxiliary illuminant is designed as a master illuminant.

19. The luminaire according to claim 18, wherein at least one further illuminant is provided which can be activated as a slave illuminant by the at least one master illuminant.

20. The luminaire according to claim 19, wherein the activation of the at least one further illuminant is effected by means of at least one photocell connected to the further illuminant.

21. The luminaire assembly comprising at least two luminaires according to claim 1, wherein a control computer is designed for continuously detecting persons by means of the motion sensors of the luminaires and for activating or deactivating auxiliary illuminants and optionally also main illuminants of luminaires based on their movement behaviour.

22. The luminaire assembly according to claim 21, wherein the movement behaviour of persons comprises at least one from the moving direction, the speed, the staying time and/or the orientation of the visual field.

23. The luminaire assembly according to claim 21, wherein the control computer is designed for guiding persons along a path through an area covered by motion sensors by activating/deactivating luminaires.
