Abstract
A luminaire includes a housing with a light exit aperture, wherein the housing houses a first light source which emits visible light and a second light source which emits ultraviolet (UV) light. The second light source is disposed within the housing between the first light source and the light exit aperture and allows at least some of the visible light emitted by the first light source to pass therethrough.
Claims24
A luminaire comprising:
- a housing including a light exit aperture defined therein;
- a first light source disposed in the housing, the first light source configured to emit visible light;
- and
- a second light source disposed in the housing between the first light source and the light exit aperture, the second light source configured to emit ultraviolet light, the second light source further configured to allow at least some of the light emitted by the first light source to pass therethrough.
A lighting system for illuminating an area, the lighting system comprising:
- a luminaire including a first light source and a second light source disposed in a housing comprising a light exit aperture, the first light source configured to emit visible light and the second light source configured to emit ultraviolet light, wherein the second light source is disposed in the housing between the first light source and the light exit aperture and configured to allow at least some of the visible light emitted by the first light source to pass through;
- a sensor configured to detect occupancy of the area;
- and
- a controller operatively coupled to the second light source and the sensor, the controller configured to receive one or more signals from the sensor, determine if the area is occupied, and if the area is occupied, illuminate the second light source.
The lighting system 17, wherein the sensor comprises includes one of:
- (i) a motion sensor, (ii) a temperature sensor, or (iii) an audio sensor.
A lighting system for illuminating an area, the lighting system comprising:
- a luminaire including a first light source and a second light source disposed in a housing comprising a light exit aperture, the first light source configured to emit visible light and the second light source configured to emit ultraviolet light, wherein the second light source is disposed in the housing between the first light source and the light exit aperture and configured to allow at least some of the visible light emitted by the first light source to pass through;
- a light switch configured to illuminate the first light source;
- and
- a controller operatively coupled to the second light source and the light switch, the controller configured to
- determine the light switch has been engaged, illuminate the second light source, and
- after a predetermined amount of time, turn off the second light source.
A lighting system for illuminating an area, the lighting system comprising:
- a luminaire including a first light source and a second light source disposed in a housing comprising a light exit aperture, the first light source configured to emit visible light and the second light source configured to emit ultraviolet light, wherein the second light source is disposed in the housing between the first light source and the light exit aperture and configured to allow at least some of the visible light emitted by the first light source to pass through;
- a controller operatively coupled to the second light source, the controller configured to periodically illuminate the second light source regardless of occupancy of the area.
