Abstract

Embodiments of the invention include a luminaire that includes a plurality of different light engines. Light engines having different light distributions can be included in a single luminaire and a subset of the light engines selectively driven to dynamically change the light distribution of the luminaire. In this way, a single luminaire is capable of illuminating an area with a variety of different light distributions.

Claims

1. A luminaire comprising:

a sensor

a first light engine configured to create a first light distribution;

a second light engine configured to create a second light distribution different from the first light distribution; and

a controller communicatively coupled with the sensor, the first light engine and the second light engine, wherein the controller is configured to;

determine when a trigger event occurs based on data from the sensor; and

dim down at least one of the light engines,

wherein the first light distribution and the second light distribution do not overlap.

2. The luminaire of claim 1, wherein the first light engine comprises:

inner zone optics that produce an inner zone light distribution; and

outer zone optics that produce an outer zone light distribution.

3. The luminaire of claim 2, wherein the inner zone light distribution and the outer zone light distribution do not overlap.

4. The luminaire of claim 1, wherein the sensor comprises a rain sensor.

5. The luminaire of claim 1, wherein the sensor comprises a temperature sensor.

6. The luminaire of claim 1, wherein the sensor comprises a daylight sensor.

7. The luminaire of claim 1, wherein the sensor comprises a humidity sensor.

8. The luminaire of claim 1, wherein the sensor comprises a particle sensor.

9. The luminaire of claim 1, wherein the sensor comprises a luminance sensor.

10. The luminaire of claim 1, wherein the sensor comprises a motion sensor.

11. The luminaire of claim 1, wherein the sensor comprises an input for manual control.
