Abstract

Techniques presented herein are directed to the coordinated network-based control of the color capabilities of multi-color fixtures. A network device is connected to multi-color light fixtures each comprising a local processor and a plurality of color light emitters. The network device receives data inputs from one or more data sources and uses the data inputs to identify a color informational display for presentation across a plurality of the multi-color light fixtures. The network device generates messages encoding light control settings for each of the plurality of multi-color light fixtures enabling each multi-color light fixture to present a spatial or temporal segment of the color informational display and sends the messages to the plurality of light fixtures. Execution of instructions embedded in the messages by the local processors results in the creation of the color informational display across the plurality of multi-color light fixtures.

First claim

What is claimed is:

1. A method comprising:
receiving, at a network device connected to a plurality of multi-color light fixtures each comprising a local processor and a plurality of color light emitters, a query requesting a location of a specific target;
identifying the location of the specific target;
identifying a location associated with a source of the query;
identifying, based on the query, a color informational display for presentation across the plurality of the multi-color light fixtures;
generating messages encoding light control settings enabling one or more multi-color light fixtures in proximity to the specific target to present a color informational display that identifies the location of the specific target and that is visible from the location associated with the source of the query; and
sending the messages to the plurality of light fixtures for execution by the local processors to create the color informational display across the plurality of multi-color light fixtures.

2. The method of claim 1 , wherein the plurality of color light emitters in a multi-color light fixture comprise multi-color light emitting diodes (LEDs) that include red, green, and blue emitters, and wherein the multi-color LEDs are arranged into rows and columns forming a pixel color display.

3. The method of claim 1 , further comprising:
validating the query to determine whether the query complies with one or more predefined policies.

4. The method of claim 1 , further comprising:
generating messages encoding light control settings enabling the one or more multi-color light fixtures between the location associated with the source of the query and the specific target to generate a color informational display identifying a route from the location associated with the source of the query to the specific target.

5. The method of claim 4 , wherein the color informational display identifying the route from the location associated with the source of the query to the specific target is a chasing light display.

6. The method of claim 1 , wherein sending the messages to the plurality of light fixtures comprises:
sending the messages via Power over Ethernet (POE).

7. The method of claim 1 , wherein at least one of the multi-color light fixtures comprises a light emission area divided into a plurality of emitting zones angled in different directions.

8. The method of claim 7 , wherein the light emission area has a generally pyramidal frustum shape with four lateral faces and an outer medial face, wherein each of the four lateral faces and the outer medial face each corresponds to an emitting zone that each emits light at different angles.

9. The method of claim 8 , wherein the four lateral faces are angled at approximately forty-five (45) degrees relative to the outer medial face.

10. The method of claim 7 , wherein each emitting zone includes warm white light emitting diodes (LEDs), cool white light LEDs, and multi-color LEDs that include red, green, and blue emitters.

11. The method of claim 7 , wherein the light emission area has a plurality of co-planar emitting zones each including a plurality of emitters, and wherein emitters in each of the emitting zones are angled such that each emitting zone emits light at different angles.

12. The method of claim 1 , wherein the messages encoding light control settings for each of the plurality of multi-color light fixtures comprise messages that includes brightness values for multiple color channels in each of the plurality of multi-color light fixtures.

13. The method of claim 1 , wherein the messages encoding light control settings comprise messages that include multiple temporal frames that are sequentially displayed on each of the plurality of multi-color light fixtures.

14. An apparatus, comprising:
one or more network interface devices connected to a plurality of multi-color light fixtures each comprising a local processor and a plurality of color light emitters;
a memory; and
a processor that:
receives a query requesting a location of a specific target,
identifies the location of the specific target,
identifies a location associated with a source of the query,
identifies, based on the query, a color informational display for presentation across the plurality of the multi-color light fixtures,
generates messages encoding light control settings enabling one or more multi-color light fixtures in proximity to the specific target to present a color informational display that identifies the location of the specific target and that is visible from the location associated with the source of the query control settings for each of the plurality of multi color light fixtures enabling each multi, and
sends the messages to the plurality of light fixtures for execution by the local processors to create the color informational display across the plurality of multi-color light fixtures.

15. The apparatus of claim 14 , wherein the processor:
validates the query to determine whether the query complies with one or more predefined policies.

16. The apparatus of claim 14 , wherein the processor further:
generates messages encoding light control settings enabling the one or more multi-color light fixtures between the location associated with the source of the query and the specific target to generate a color informational display identifying a route from the location associated with the source of the query to the specific target.

17. The apparatus of claim 16 , wherein the color informational display identifying the route from the location associated with the source of the query to the specific target is a chasing light display.

18. The apparatus of claim 14 , wherein to send the messages to the plurality of light fixtures, the processor:
sends the messages via Power over Ethernet (POE).

19. One or more non-transitory computer readable storage media encoded with software comprising computer executable instructions and when the software is executed operable to:
receive, at a network device connected to a plurality of multi-color light fixtures each comprising a local processor and a plurality of color light emitters, a query requesting a location of a specific target;
identify the location of the specific target;
identify a location associated with a source of the query;
identify, based on the data inputs, a color informational display for presentation across the plurality of the multi-color light fixtures;
generate messages encoding light control settings enabling one or more multi-color light fixtures in proximity to the specific target to present a color informational display that identifies the location of the specific target and that is visible from the location associated with the source of the query; and
send the messages to the plurality of light fixtures for execution by the local processors to create the color informational display across the plurality of multi-color light fixtures.

20. The computer readable storage media of claim 19 , further comprising instructions operable to:
validate the query to determine whether the query complies with one or more predefined policies.

21. The computer readable storage media of claim 19 , further comprising instructions operable to:
generate messages encoding light control settings enabling the one or more multi-color light fixtures between the location associated with the source of the query and the specific target to generate a color informational display identifying a route from the location associated
