Abstract
Sectorized Visual Light Communication (VLC)/Dark Light Communication (DLC) systems and sensors are generally disclosed. The exemplary VLC/DLC systems may include a transmitter for transmitting a light signal including information about the transmitting light source, and a receiver with a number of surface facets facing in different directions at different angles, and configured to determine a distance and a direction of a transmitting light source from the VLC/DLC receiver. Associated exemplary methods for automatic identification and grouping of light sources are disclosed.
Claims20
A sectorized Visual Light Communication (VLC)/Dark Light Communication (DLC) sensor, comprising:
- a plurality of surface facets, wherein each of the plurality of surface facets is oriented in a specific direction and angle with respect to the sectorized VLC/DLC sensor and other surface facets of the plurality of surface facets,
- wherein each of the plurality of surface facets includes a distribution of pixels within a photosensitive area of the surface facet, and
- wherein the sectorized VLC/DLC sensor is configured to determine a direction and a distance of one or more transmitting light sources based on receiving light transmitted from the one or more transmitting light sources at the distribution of pixels.
A system for automatic luminaire location identification and group assignment, comprising:
- a gateway for transmitting information to a server;
- and
- a sectorized Visual Light Communication (VLC)/Dark Light Communication (DLC) sensor,
- wherein the sectorized VLC/DLC sensor includes a plurality of surface facets, wherein each facet of the plurality of surface facets is oriented in a specific direction and angle with respect to the sectorized VLC/DLC sensor and other surface facets of the plurality of surface facets,
- wherein each surface facet of the plurality of surface facets includes a distribution of pixels within a photosensitive area,
- wherein the sectorized VLC/DLC sensor is configured to transmit information associated with light that is received at the distribution of pixels from a transmitting light source to the gateway, the transmitted information associated with the distribution of pixels that receive the light and an intensity of the light that is received by the distribution of pixels,
- wherein the gateway is configured to transmit the information to the server to determine a location of the transmitting light source based on the transmitted information.
A method of automatic luminaire location identification, comprising:
- receiving light transmitted from one or more transmitting light sources at a sectorized Visual Light Communication (VLC)/Dark Light Communication (DLC) sensor, wherein
- the sectorized VLC/DLC sensor includes a plurality of surface facets,
- each of the plurality of surface facets is oriented in a specific direction and angle with respect to the sectorized VLC/DLC sensor and other facets of the plurality of surface facets, and
- each facet of the plurality of surface facets includes a distribution of pixels within a photosensitive area of the facet;
- transmitting information regarding light received at the distribution of pixels from the sectorized VLC/DLC sensor to a gateway;
- and
- transmitting, via the gateway, the information regarding light received at the distribution of pixels to a server wherein the server is configured to determine a location of the one or more transmitting light sources based on the transmitted information.
