摘要： The present disclosure relates to the field of luminaire control systems and discloses a system (100) for dynamic switching control of a luminaire (116). The system (100) comprises an ambient light sensor (102), an infrared sensor (104), and a control unit (106). The ambient light sensor (102) senses ambient illumination level and generates a light detection signal representative of the sensed ambient illumination level. The infrared sensor (104) senses infrared radiation of ambient light in the vicinity of the luminaire (116) and generates an infrared radiation detection signal. The control unit (106) cooperates with the ambient light sensor (102) and the infrared sensor (104) to generate a control signal for controlling the operation of the luminaire (116). The control unit (106) also updates the pre-determined turn on and turn off threshold lux values based on level of contamination on the surface of the ambient light sensor (102).
