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.

First claim

That which is claimed:

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.
