Abstract

The present invention relates to a data generating system comprising a memory device (302), which comprises memory cells (306, 308) and a cell content access unit (310) arranged to access content in the memory cells and provide corresponding output data, wherein the output data originating from at least one of the memory cells (306) is changeable by means of an external physical effect acting directly on the memory device.

Claims

1-6. -6. (canceled)

7. A lighting device comprising a light source, and a data generating system connected with the light source, wherein with the data generating system comprises memory cells and a cell content access unit arranged to access content in the memory cells and provide corresponding output data, wherein the output data originating from at least one of the memory cells is changeable by means of an external physical effect acting directly on the memory device, wherein the external physical effect is generated within the lighting device, and wherein the external physical effect constitute at least one physical effect of a group of physical effects comprising temperature, visible light, non-visible light, electric fields and magnetic fields.

8. The lighting device according to claim 7, wherein the data generating system is arranged to register a lighting device property that changes during operation of the lighting device.

9. The lighting device according to claim 7, wherein the lighting device is arranged to modulate its light output with the output data from the data generating system.

12. The lighting device according to claim 7, wherein the lighting device is arranged to employ the output data for internal settings.

13. The lighting device according to claim 7, said at least one of the memory cells comprising at least one memory cell being sensitive to an external physical effect generated within the lighting device and at least one memory cell being sensitive to an external physical effect received from the surroundings of the lighting device.

14. The lighting device according to claim 7, said data generating system comprising a data output trigger, which triggers data output from the memory device.

15. The lighting device according to claim 7, said output data being changeable by said at least one of the memory cells being receptive to the external physical effect for changing the contents of said at least one memory cell.

16. The lighting device according to claim 7, said output data being changeable by said content access unit being receptive to the external physical effect for changing its interpretation of the content of said at least one of the memory cells.

17. The lighting device according to claim 7, said at least one of the memory cells comprising at least one memory cell which is provided with a temperature sensitive leakage.

18. The lighting device according to claim 7, said at least one of the memory cells comprising at least one memory cell which is light sensitive.
