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.
Claims9
A lighting device comprising a light source, and a data generating system connected with the light source,
- wherein 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,
- wherein the external physical effect constitutes at least one physical effect of a group of physical effects comprising temperature, visible light, non-visible light, electric fields and magnetic fields, and
- wherein the data generating system is arranged to register a lighting device property that changes during operation of the lighting device.
