Abstract

A light fixture is described herein. The light fixture can include at least one light source. The light fixture can also include a controller coupled to the at least one light source, where the controller controls an output of the at least one light source based on a location of the light fixture in a facility.

First claim

What is claimed is:

1. A lighting system, comprising:
at least one first light source having a first normal operation mode and a first environmental condition operation mode, wherein the first normal operation mode is associated with a standard emission of light by the at least one light source, and wherein the first environmental condition operation mode is associated with emitting a non-standard emission of light by the at least one light source;
a first controller operatively coupled to the at least one first light source; and
at least one sensor that measures a first parameter of a first environmental condition, wherein the first environmental condition is unassociated with the first normal operation mode of the at least one light source,
wherein the first controller receives first data from the at least one sensor and evaluates the first parameter measured by the at least one sensor,
wherein the first normal operation mode comprises at least one of a first group consisting of steady-state operation of the at least one light source in an on and off state, and steady-state variation of an intensity level of the at least one light source,
wherein the first environmental condition operation mode comprises at least one of a second group consisting of a transient on and off state of the at least one light source, transient changes of the intensity level of the at least one light source, and changes in spectrum of the light output by the at least one light source, and
wherein the first controller, upon determining that the first parameter measured by the at least one sensor falls outside a first range of acceptable values, causes the at least one first light source to emit the non-standard emission of light in the first environmental condition operation mode based on the first data.

2. The lighting system of claim 1 , wherein the at least one first light source further has a second environmental condition operation mode, wherein the at least one sensor further measures a second parameter of a second environmental condition, wherein the second environmental condition is unassociated with the first normal operation mode of the at least one first light source, wherein the first controller further receives second data from the at least one sensor and evaluates the second parameter measured by the at least one sensor, and wherein the first controller, upon determining that the second parameter falls outside a second range of acceptable values, changes the at least one first light source to the second environmental condition operation mode based on the second data.

3. The lighting system of claim 1 , wherein the at least one first light source emits a first light spectrum during the first normal operation mode, and wherein the at least first one light source emits a second light spectrum during the first environmental condition operation mode.

4. The lighting system of claim 1 , wherein the at least one first light source emits a constant emission of light during the first normal operation mode, and wherein the at least one first light source emits an interval emission of the light during the first environmental condition operation mode.

5. The lighting system of claim 1 , wherein the at least one sensor is located outside a housing of a light fixture and is intrinsically safe.

6. The lighting system of claim 1 , further comprising a housing, wherein the housing meets applicable standards for a hazardous environment.

7. The lighting system of claim 1 , wherein the first controller further controls the at least one first light source based on a location of the at least one first light source, wherein the location is assigned a designation by a user, wherein the first environmental condition operation mode of the at least one light source corresponds to the designation.

8. The lighting system of claim 7 , further comprising:
at least one second light source having a second normal operation mode and a second environmental condition operation mode; and
a second controller operatively coupled to the at least one second light source and the first controller,
wherein the second controller receives a communication from the first controller, wherein the communication instructs the second controller to operate the at least one second light source from the second normal operation mode to the second environmental condition operation mode,
wherein the communication is based on the first parameter measured by the at least one sensor.

9. The lighting system of claim 7 , wherein the at least one first light source comprises a first light source at a first location and a second light source at a second location, wherein the first location of the first light source is proximate to an event that causes the at least one parameter measured by the at least one sensor to fall outside the range of acceptable values, and wherein the second location of the second light source is remote from the event.

10. The lighting system of claim 1 , wherein the controller comprises:
a hardware processor;
memory comprising a plurality of instructions;
a control engine that executes the plurality of instructions on the hardware processor, wherein the control engine is configured to control and communicate with the at least one sensor, and
wherein the control engine controls the at least one first light source based on a plurality of detections made by the at least one sensor.

11. The lighting system of claim 1 , wherein the at least one sensor is a first sensor among a plurality of sensors, wherein the at least one light source is a first light source among a plurality of light sources, wherein the at least one environmental condition is among a plurality of environmental conditions, wherein a sensor of the plurality of sensors located proximate to an unacceptable environmental condition measures the at least one parameter of the unacceptable environmental condition, wherein the first controller, upon determining that the at least one parameter falls outside the range of acceptable values, controls a light source of the plurality of light sources located closest to the unacceptable environmental condition to operate in the first environmental condition operation mode, wherein the light source is controlled by the first controller based on the unacceptable environmental condition.

12. The lighting system of claim 1 , wherein the first environmental condition comprises at least one selected from a group consisting of a gas leak, a fire, an equipment failure, a power outage, an accident, a weather condition, a bird migration season, a turtle hatching season, a presence of wildlife, and a falcon nesting season.

13. The lighting system of claim 1 , wherein light emitted by the at least one light source between the first normal operation mode and the first environmental condition operation mode has at least one difference selected from a group consisting of a frequency, a spectrum, and an intensity.

14. A controller of a lighting system, the controller comprising:
memory comprising a plurality of instructions that correspond to detection of at least one environmental condition, wherein the at least one environmental condition is associated with an environmental condition operation mode of the lighting system and is unassociated with a normal operation mode of the lighting system; and
a control engine coupled to the memory, wherein the control engine is configured to:
evaluate at least one parameter associated with the at least one environmental condition measured by at least one sensor;
control, upon determining that the at least one parameter measured by the at least one sensor is
