Data on light bulb
View Patent ↗A light-emitting device includes a plurality of ultra-small resonant structures, each of said structures constructed and adapted to emit electromagnetic radiation (EMR) at a particular wavelength when a beam of charged particles is passed nearby. A combiner mechanism constructed and adapted to combine data from a data source with the EMR emitted by at least one of the ultra-small resonant structures.
1. A light-emitting device comprising:
a plurality of ultra-small resonant structures, each of said structures constructed and adapted to emit ambient electromagnetic radiation (EMR) at a particular wavelength when a beam of charged particles is passed nearby; and
a combiner mechanism constructed and adapted to combine data from a data source with the EMR emitted by at least one of the ultra-small resonant structures.
2. A device as in claim 1 wherein at least two of said ultra-small resonant structures emit light at different wavelengths.
3. A device as in claim 2 wherein at least one of the ultra-small resonant structures emits EMR within the visible range of light.
4. A device as in claim 1 wherein data from the data source are modulated onto the EMR emitted by at least one of the ultra-small resonant structures.
5. A device as in claim 1 wherein the combiner mechanism combines data from the data source with the EMR emitted by more than one of the ultra-small resonant structures.
6. A device as in claim 2 wherein the data are combined with light of at least two different wavelengths.
7. A device as in claim 3 wherein the data are combined with EMR outside of the visible range.
8. A method comprising:
providing a fixture which includes a plurality of ultra-small resonant structures which emit ambient electromagnetic radiation (EMR) when exposed to a beam of charged particles;
providing a data source;
combining data from the data source with EMR from the fixture to produce EMR that contains the data.
9. A method as in claim 8 wherein the EMR covers a plurality of wavelengths.
10. A method as in claim 9 wherein at least one of the wavelengths is within the visible range of light.
11. A method as in claim 9 wherein the data are combined with EMR of more than one wavelength.
12. A method as in claim 11 wherein the data are combined with EMR of at least one non-visible wavelength.
13. A method of controlling an electronic device, the method comprising:
providing control data for the electronic device to a light fixture including ultra-small light-emitting resonant structures which emit electromagnetic radiation when exposed to a beam of charged particles;
emitting light from said light fixture, said light encoded with said control data for said electronic device.
14. A method as in claim 13 further comprising:
detecting said light including said control data;
extracting said control data from said light; and
controlling said device based, at least in part, on said extracted control data.
15. A light bulb comprising:
an ultra-small resonant structure which emits electromagnetic radiation when exposed to a beam of charged particles broadcasting light to a local device, said light being encoded with data; and
an encoder to encode data with the emitted light for receipt by the local device.
