Abstract

A lighting system comprising a light source operable to emit a source light, a sensor operable to sense environmental light from an environment, and a controller operatively connected to each of the sensor and the light source and configured to analyze the environmental light sensed by the sensor to at least one of detect and generate data relating to a condition of the environment, the data being transmittable in a transmitted data light. The sensor is operable to sense the presence or absence of a dominant wavelength comprised by the environmental light. Additionally, the controller is operable to correlate the dominant wavelength with a substance.

Claims (31)

1. A lighting system comprising:

a light source operable to emit a source light;

a sensor operable to sense environmental light from an environment; and

a controller operatively connected to each of the sensor and the light source and configured to analyze the environmental light sensed by the sensor to at least one of detect and generate data relating to a condition of the environment, the data being transmittable in a transmitted data light;

wherein the sensor is operable to sense the presence or absence of a dominant wavelength comprised by the environmental light;

wherein the controller is operable to correlate the dominant wavelength with a substance;

wherein the controller is operable to establish a normal level of the dominant wavelength indicative of the substance;

wherein the controller is operable to determine a detected level of the dominant wavelength indicative of the substance; and

wherein the controller is operable to determine if a difference between the normal level and the detected level of the dominant wavelength indicative of the substance is above a threshold level.

2. The lighting system according to claim 1 wherein the controller is operable to operate the lighting system to generate an alert responsive to determining the difference between the normal level and the detected level of the dominant wavelength indicative of the substance is above the threshold level.

3. The lighting system according to claim 1 further comprising a network comprising a plurality of lighting systems connected thereto; wherein the controller is operable to compare the difference between the normal level and the detected level of the dominant wavelength indicative of the substance with information included in the memory of another lighting system connected to the network.

4. The lighting system according to claim 1 wherein the controller is operable to determine whether light emitted by the source light and reflected by the substance is comprised by the environmental light.

5. The lighting system according to claim 1 further comprising a conversion material operable to receive light reflected by the substance and emit a converted environmental light.

6. The lighting system according to claim 5 wherein:

the sensor is operable to sense the converted environmental light;

the controller is operable to determine a detected level of the converted environmental light; and

the controller is operable to determine if a difference between the normal level of the dominant wavelength indicative of the substance and the detected level of the converted environmental light is above a threshold.

7. The lighting system according to claim 6 wherein the controller is operable to operate the lighting system to generate an alert responsive to determining the difference between the normal level of the dominant wavelength indicative of the substance and the detected level of the converted environmental light is above the threshold level.

8. The lighting system according to claim 6 further comprising a network comprising a plurality of lighting systems connected thereto;

wherein the controller is operable to compare the difference between the normal level of the dominant wavelength indicative of the substance and the detected level of the converted environmental light with information included in the memory of another lighting system connected to the network.

9. The system according to claim 1 further comprising a conversion material operable to absorb at least a portion of the source light emitted by the light source and emit a converted light.

10. A lighting system comprising:

a light source operable to emit a source light;

a sensor operable to sense environmental light from an environment;

a controller operatively connected to each of the sensor and the light source and configured to analyze the environmental light sensed by the sensor to at least one of detect and generate data relating to a condition of the environment, the data being transmittable in a transmitted data light; and

a conversion material operable to receive light reflected by the substance and emit a converted environmental light;

wherein the sensor is operable to sense the presence or absence of a dominant wavelength comprised by the environmental light;

wherein the controller is operable to correlate the dominant wavelength with a substance;

wherein the sensor is operable to sense the converted environmental light;

wherein the controller is operable to determine a detected level of the converted environmental light; and

wherein the controller is operable to determine if a difference between the normal level of the dominant wavelength indicative of the substance and the detected level of the converted environmental light is above a threshold.
