18 Claims

1. An automated luminaire comprising:

a range sensing module configured to emit first light pulses in a first direction along a first axis to calculate a measured distance to a closest object in the first direction; and

a control system configured to:

receive from the range sensing module the measured distance; and

reduce an emitted beam power density of a second emitted light beam emitted from the automated luminaire along a second axis when a value of the measured distance is less than a predetermined threshold distance value, wherein the first axis and the second axis are not coaxial.
