Abstract

A lighting device or an apparatus for use with a light source has one or more sensors, intelligence in the form of programmed processors and communication capabilities. Each sensor is configured to monitor one or more conditions external to a lighting device not directly related to operational performance of the respective lighting device. Programming provides a standardized interface to enable processing of sensed conditions from sensors of different types.

Claims

1. An apparatus for use with a light source, the apparatus comprising:

a sensor coupling configured to present a standardized sensor connection interface, the standardized sensor connection interface being compatible with a plurality of different types of sensors;

a first sensor connected to the standardized sensor connection interface of the sensor coupling, the first sensor being of one of the different types and located so as to sense one of a plurality of external conditions not directly related to operation or control of the light source, the first sensor being configured to output a signal responsive to the sensed external condition via the standardized sensor connection interface of the sensor coupling;

a second sensor of different type than the first sensor and located so as to sense a condition related to operation of the light source, the second sensor being configured to output a second signal responsive to the sensed condition related to operation of the light source;

a processor coupled to the sensor coupling;

a communication interface accessible by the processor;

a memory accessible to the processor; and

programming stored in the memory, wherein execution of the programming by the processor configures the processor to implement functions, including functions to;

receive, in a standardized signal format, the signal from the first sensor;

deliver, in a standardized data format and based at least in part on the signal, first data representing the external condition sensed by the first sensor to a first application program corresponding at least in part to the one type of the first sensor;

deliver, in the standardized data format and based at least in part on the signal, second data representing the external condition sensed by the first sensor to a second application program corresponding at least in part to the one type of the first sensor, wherein the second application program is different from the first application program;

enable processing of the first data representing the sensed external condition by the processor on behalf of the first application program;

enable processing of the second data representing the sensed external condition by the processor on behalf of the second application program;

communicate, in a standardized communications format enabled by the programming and to a first destination, first information resulting from processing of the first data representing the sensed external condition;

communicate, in the standardized communications format enabled by the programming and to a second destination, second information resulting from processing of the second data representing the sensed external condition;

receive the second signal from the second sensor;

deliver, based at least in part on the second signal, third data representing the condition related to operation of the light source to a third application program;

enable processing of the third data representing the condition related to operation of the light source by the processor on behalf of the third application program; and

control operation of the light source at least in part responsive to the processing of the third data representing the condition related to operation of the light source;

wherein;

the programming implements a standard application programming interface for the first and second application programs, and

the programming implements a different standard application programming interface for the third application program.

2. The apparatus of claim 1, wherein the function to communicate the first information and the function to communicate the second information both utilize the communication interface.

3. The apparatus of claim 1, further comprising a second communication interface, wherein:

the function to communicate the first information utilizes the communication interface; and

the function to communicate the second information utilizes the second communication interface.

4. The apparatus of claim 3, further comprising a local wireless transceiver coupled to the second communication interface.

5. The apparatus of claim 1, further comprising:

a module housing containing at least the processor, memory and communication interface,

wherein the housing is configured for mounting together with a fixture containing the light source.

6. The apparatus of claim 5, wherein the processor also is coupled to control the light source.

7. The apparatus of claim 1, wherein further execution of the programming by the processor configures the processor to implement further functions, including functions to:

communicate, in the standardized communications format enabled by the programming and to a third destination, third information resulting from processing of the third data representing the condition related to operation of the light source.

8. The apparatus of claim 1, wherein:

the implemented standard application programming interface defines;

the standardized signal format; and

the standardized data format;

the implemented different standard application programming interface defines;

a different standardized signal format; and

a different standardized data format;

the third data representing the condition related to operation of the light source is delivered in the different standardized data format.

9. The apparatus of claim 1, further comprising:

an output driver, coupled for control by the processor, configured to drive an information output device coupled to the apparatus,

wherein further execution of the programming by the processor further configures the processor to implement functions, including functions to;

receive, from the network via the communication interface and in the standardized communication format enabled by the programming, information for local output; and

operate the at least one output driver to cause the information output device to reproduce the received information.
