Abstract

A luminaire for disinfecting a target surface includes a disinfecting light source, a non-disinfecting light source, a beam angle adjustor, a motion sensor, and a distance sensor. The radiance of the disinfecting light is calculated based on detected distance to a target surface and beam angle, and may be selected to achieve a predetermined irradiance of the target surface. If no motion is detected by the motion sensor then the disinfecting light source is set to ON and the non-disinfecting light source is set to OFF. If motion is detected and a beam intercept is not detected by the distance sensor then the disinfecting light source is set to DIM and the non-disinfecting light source is set to ON. If motion is detected and a beam intercept is detected then the disinfecting light source is set to OFF and the non-disinfecting light source is set to ON.
