Abstract: Methods and apparatus for lighting control. One or more properties of light output of one or more LEDs (124A, 124B, 124C, 124N) of an LED node (120A, 120B, 120C, 120N) of an LED-based lighting unit (110) are controlled to extend the lifetime of the LED-based lighting unit. For example, an LED node controller controlling an LED may determine whether the LED will be operated in the active light emitting state based on an LED activation probability. Thus, based on the LED activation probability the LED may at some times be in the active light emitting state and provide light output and may at other times be prevented from being in the active light emitting state and prevented from providing light output.

Abstract: Disclosed are methods and apparatus for lighting control. For example, a user may commission a touch-controlled luminaire (106) to emit light output having various lighting properties dependent on a manner in which the touch-controlled luminaire is touched subsequently. In particular, a user may use an electronic mobile device (102) such as a smart phone, tablet computer, or a wearable computing device (e.g., computing glasses, smart watches) to associate a touch event profile indicative of a manner in which a touch-controlled luminaire was touched (e.g., tapped, swiped, etc.) with a lighting control action. The user may then provide that association to the touch-controlled luminaire. When the touch-controlled luminaire is later touched in the same manner, it may adjust its light output in accordance with the lighting control action. Operation and commission of gesture-controlled luminaires (706) is also described herein.
