  • Method of controlling a lighting device
    Patent number: 9775216
    Abstract: According to an aspect of the invention, a method of controlling a lighting device is provided. The method comprises receiving an input from a dimmer, the input being representative of a desired light output level for the lighting device. A control voltage for operating a driver unit comprised in the lighting device is computed based on the input and a calibrated relationship between power consumption and control voltage for the lighting device.
    Type: Grant

  • Lighting control system
    Patent number: 8040239
    Abstract: A lighting control system (1) comprises: a communication bus (2); at least one extension movement detector (30) issuing detection pulses (DOS) over said communication bus in response to detecting a movement, at first time intervals (T1) determined by a sensor timer (34); one master luminaire (10) comprising a lamp (11) and a master controller (13) issuing master command signals (MCS) over said bus in response to detection pulses (DOS) received over said bus; and at least one slave luminaire (20) comprising a lamp (21) and a slave controller (23) being responsive to the master control signals (MCS) received over said bus to switch the corresponding lamp ON and OFF. Whenever the master controller receives a detection pulse, it starts a master timer (15) and switches the lamps ON. If the master timer times out (T2) without the master controller receiving any detection pulses, the master controller switches the lamps OFF.
