Abstract

Claims (40)

1. A disinfecting LED lighting system comprising:

at least one light fixture disposed in a ceiling in an environment and configured to output a first light and a second light, wherein the first light and the second light are emitted from independent sources and operate independently; and wherein:

the first light and the second light both emit a portion of a spectral range as a disinfecting energy within a disinfecting wavelength range of 380 to 420 nanometers,

the first light emits a first output wherein at least 20% of the spectral range is within the disinfecting wavelength range; and

the second light emits a second output wherein at least 70% of the spectral range is within the disinfecting wavelength range; and

at least one sensor in communication with the at least one light fixture and configured to detect a characteristic of the environment, wherein the characteristic of the environment is an amount of disinfecting energy, and wherein the at least one sensor is configured to detect an amount of natural light disinfecting energy and detect an amount of disinfecting energy of the first light and the second light within the disinfecting wavelength range of 380 to 420 nanometers; and

a controller in communication with the at least one sensor and the at least one light fixture and configured to cause an event.

2. The disinfecting LED lighting system of claim 1 , wherein the event comprises:

using the characteristic of the environment detected by the sensor to determine if the first light or the second light will be operated; and

operating only the first light or only the second light.

3. The disinfecting LED lighting system of claim 1 , wherein the event comprises:

detecting the first output of the first light or the second output of the second light, the output correlating to an amount of disinfecting energy;

comparing the disinfecting energy of the first output of the first light or the disinfecting energy of the second output of the second light to a required target dosage of disinfecting energy; and

adjusting the output of the first light or the output of the second light to meet the required target dosage of disinfecting energy.

4. The disinfecting LED lighting system of claim 3 , wherein the controller is further configured to adjust the output of the first light or the output of the second light without varying an output ratio of disinfecting energy.

5. The disinfecting LED lighting system of claim 1 , wherein the characteristic of the environment is an occupancy of the environment, and wherein the controller is configured to operate the first light when the occupancy is detected in the environment; and wherein the controller is configured to operate the second light when the occupancy is not detected in the environment.

6. The disinfecting LED lighting system of claim 5 , wherein at least one sensor is configured to detect a number of users that occupy the environment.

7. The disinfecting LED lighting system of claim 1 , further comprising a plurality of light fixtures disposed within the environment and in communication with each other.

8. The disinfecting LED lighting system of claim 7 , wherein the controller is in communication with a computing system configured to control operation of the plurality of light fixtures and other operations of the environment.

9. The disinfecting LED lighting system of claim 1 , wherein the first light comprises an illuminating white light.

10. The disinfecting LED lighting system of claim 1 , wherein the controller is configured to control the output of the first light and the output of the second light based on a predetermined schedule.

11. The disinfecting LED lighting system of claim 1 , wherein the controller is in wireless communication with the at least one light fixture and the at least one sensor.

12. The disinfecting LED lighting system of claim 1 , comprising a second sensor in communication with the at least one light fixture and configured to detect a second characteristic of the environment, wherein the second characteristic is an amount of disinfecting energy provided to the environment.

13. The disinfecting LED lighting system of claim 1 , further comprising an access control component in communication with the controller and the at least one light fixture, wherein the access control component is configured to control the first light and the second light of the at least one light fixture.

14. The disinfecting LED lighting system of claim 1 , wherein the controller is configured to maintain an average amount of disinfecting energy provided to the environment or a dosage of disinfecting energy over a period of time.

15. The disinfecting LED lighting system of claim 1 , wherein the output of the first light and the output of the second light may be adjusted by adjusting a brightness or by dynamically changing an amount of light within the disinfecting wavelength range of 380 to 420 nm.

16. The disinfecting LED lighting system of claim 1 , wherein the characteristic of the environment is associated with a preferred level of illuminating light provided by the first output of the first light and a predetermined threshold of disinfecting energy provided by the first output of the first light or the second output of the second light, wherein, the predetermined threshold of disinfecting energy and the preferred level of illuminating light is stored on the controller or is provided to the controller from an external source.

17. The disinfecting LED lighting system of claim 1 , wherein the controller is disposed within the at least one lighting fixture.

18. A method of LED lighting disinfection comprising:

outputting, via a first light disposed within a first light fixture in an environment, a first output comprising at least 20% of emitted wavelengths within a disinfecting wavelength range of 380 to 420 nanometers (nm);

outputting, via a second light disposed within a first light fixture in an environment, a second output comprising at least 70% of the emitted wavelengths within the disinfecting wavelength range of 380 to 420 nm, wherein the second light is an independent source from the first light;

detecting, via a sensor in communication with the first light fixture, a characteristic of the environment, wherein the characteristic of the environment is an amount of disinfecting energy, and wherein the sensor is configured to detect an amount of natural light disinfecting energy and detect an amount of disinfecting energy of the first light and the second light within the disinfecting wavelength range of 380 to 420 nanometers; and

causing an event, via a first controller in communication with the sensor and the first light fixture.

19. The method of claim 18 , further comprising:

using the characteristic of the environment detected by the sensor to determine if the first light or the second light will be operated; and

operating only the first light or only the second light.
