Abstract

A luminaire for identifying a lamp shade is disclosed. The luminaire comprises a light source (102), a lamp shade (104) and a second luminaire component (108). The lamp shade (104) comprises at least one surface feature (106) which comprises an identifier, the identifier being representative of at least one characteristic of the lamp shade (104). The second luminaire component (108) comprises a detector (110) arranged for detecting the at least (5) one surface feature (106) of the lamp shade (104). The second luminaire component (108) further comprises a first processor (112) arranged for retrieving the identifier from the detected at least one surface feature (106), and for identifying the at least one characteristic of the lamp shade (104) based on the retrieved identifier. This allows the second luminaire component (108) to control, for example, the light output of the light source (102) based on the identified at least (10) one characteristic, or to transmit the retrieved information to a further device for further control or for informative purposes.

Claims

1. A luminaire, comprising:

a light source;

a lamp shade comprising at least one surface feature, the at least one surface feature comprising an identifier, which identifier is representative of at least one characteristic of the lamp shade; and

a luminaire component, comprising;

a detector, arranged for detecting the at least one surface feature of the lamp shade; and

a first processor arranged for retrieving the identifier from the detected at least one surface feature, and for identifying the at least one characteristic of the lamp shade based on the retrieved identifier, the first processor arranged for retrieving the at least one characteristic from a database,

wherein the first processor is arranged for controlling the light output of the light source based on the at least one characteristic of the lamp shade.

2. The luminaire of claim 1, wherein the at least one surface feature is embedded in the surface of the lamp shade.

3. The luminaire of claim 1, wherein the at least one surface feature comprised in the lamp shade comprises a protrusion and/or a depression in the surface of the lamp shade, which protrusion and/or depression comprises the identifier, and wherein the detector is arranged for detecting the protrusion and/or depression so as to detect the identifier.

4. The luminaire of claim 1, wherein the light source is arranged for illuminating at least a part of the at least one surface feature, and wherein the detector comprises an optical sensing unit arranged for detecting the at least a part of the at least one surface feature.

5. The luminaire of claim 1, wherein the detector comprises a further light source arranged for illuminating at least a part of the at least one surface feature, and wherein the detector comprises an optical sensing unit arranged for detecting the at least a part of the at least one surface feature.

6. The luminaire of claim 1, wherein at least a part of the at least one surface feature comprised in the lamp shade contains a conductive material with conductive properties different from the conductive properties of the material of the lamp shade, and wherein the detector is arranged for detecting the conductive material so as to detect the identifier.

7. The luminaire of claim 1, wherein at least a part of the detector is physically connected to the at least one surface feature.

8. The luminaire of claim 1, wherein the at least one characteristic comprises information about at least one of the group comprising:

a type of lamp shade,

a code of the lamp shade,

a light distribution of the lamp shade, and

a light setting for the lamp shade.

9. A lighting system, comprising:

the luminaire of claim 1, wherein the first processor is further arranged for generating a signal based on the retrieved identifier; and

a first device arranged for receiving the signal, the first device comprising a second processor arranged for identifying the at least one characteristic of the lamp shade based on the received signal.

10. The lighting system of claim 9, wherein the second processor is further arranged for generating a control command based on the identified at least one characteristic, and wherein the first processor is further arranged for adjusting the light output of the light source based on the control command.

11. The lighting system of claim 9, wherein the first device further comprises a user interface, wherein the user interface is further arranged for providing information to a user about the lamp shade, the information based on the at least one characteristic.

12. A luminaire, comprising:

a light source;

a lamp shade comprising at least one surface feature, the at least one surface feature comprising an identifier, which identifier is representative of at least one characteristic of the lamp shade; and

a luminaire component, comprising;

detector, arranged for detecting the at least one surface feature of the lamp shade; and

a first processor arranged for retrieving the identifier from the detected at least one surface feature, and for identifying the at least one characteristic of the lamp shade based on the retrieved identifier,

wherein the first processor is arranged for controlling the light output of the light source based on the at least one characteristic of the lamp shade, and

wherein the at least one surface feature comprised in the lamp shade is of a color different from the color of the lamp shade, which difference in color is representative of the identifier, and wherein the detector is arranged for detecting the difference in color so as to detect the identifier.

13. A luminaire component, comprising:

a detector, arranged for detecting at least one surface feature of a lamp shade, the at least one surface feature comprising an identifier, which identifier is representative of at least one characteristic of the lamp shade; and

a first processor arranged for retrieving the identifier from the detected at least one surface feature, and for identifying the at least one characteristic of the lamp shade based on the retrieved identifier, the first processor arranged for retrieving the at least one characteristic from a database,

wherein the first processor is arranged for controlling the light output of a light source based on the at least one characteristic of the lamp shade.

14. A method of identifying a lamp shade, the method comprising the steps of:

providing the lamp shade comprising at least one surface feature, the at least one surface feature comprising an identifier, which identifier is representative of at least one characteristic of the lamp shade;

providing a luminaire component;

detecting, by the luminaire component, the at least one surface feature of the lamp shade;

retrieving the identifier from the detected at least one surface feature;

identifying the at least one characteristic of the lamp shade based on the retrieved identifier;

retrieving the at least one characteristic of the lamp shade from a database; and

controlling the light output of a light source based on the at least one characteristic of the lamp shade.
